Immune checkpoint inhibitors have revolutionized cancer treatment, but they are associated with a range of immune-related adverse events (irAEs), and emerging evidence suggests significant sex differences in the incidence, type, and severity of these toxicities, suggesting an influential factor and understanding sex-related differences in irAEs as crucial for optimizing patient care and improving clinical outcomes. In MOUSEION-07 study, we aimed to assess the association between sex and treatment-related adverse events in cancer patients treated with immunotherapy through a large up-to-date meta-analysis of available clinical trials. The present systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis. The protocol was registered with PROSPERO no. CRD42024549518. Sixteen studies encompassing a total of 4658 patients were included, and 2133 adverse effects were highlighted. The analysis observed a not statistically significant difference in terms of immune-related adverse events (irAEs) between males and females (Odds Ratio 1.19; CI 0.88-1.63) and revealed the presence of publication bias (β = -2.53; 95% CI = [-4.03; -1.04]; P = 0.006). Sex differences in immunotherapy-related adverse events are a significant factor in cancer treatment, necessitating a personalized approach to patient care. Further research is needed to fully understand the mechanisms driving these differences and to develop optimized strategies for monitoring and managing irAEs in both females and males., Competing Interests: Competing interests The authors declare no competing interests., (© 2024.

Background: Immune checkpoint inhibitors (ICIs) have been employed in the adjuvant and metastatic setting of renal cell carcinoma (RCC) treatment. Among ICIs, combined immunotherapy has the highest risk for immune-related adverse events (irAEs). We aimed to document the incidence of irAEs in RCC patients treated with nivolumab and ipilimumab as data from the European population remain limited., Materials and Methods: We analysed data from 88 RCC patients treated with nivolumab + ipilimumab between May 2022 and June 2024 across six high-volume oncology units in Poland. We reviewed irAEs and estimated their impact on survival parameters via univariate and multivariate Cox proportional hazards regression models, along with log-rank tests., Results: With a median follow-up of 11.3 months, the median overall survival (OS) was not reached, whereas the median progression-free survival (PFS) was 12.8 months (6.3-19.3). A total of 74 irAEs were recorded in 50 patients. The most frequent events were endocrine (n = 20, 27%), hepatic (n = 15, 17%), general (n = 12, 13.6%), and cutaneous (n = 11, 12.5%). The occurrence of irAEs was associated with a 60% lower risk of disease progression (hazard ratio 0.44, 95% confidence interval 0.2-0.87, p = 0.018) without impacting OS and higher disease control rate (n = 45, 90% vs. n = 24, 63.2%, p = 0.004). In contrast, patients with hepatotoxicity had poorer outcomes, with a 2.6-fold greater risk of death (p = 0.05)., Conclusions: IrAEs may serve as a predictive factor for the efficacy of the nivolumab + ipilimumab regimen in RCC patients. Special attention is needed for hepatotoxicity, as it can significantly impact survival outcomes., Competing Interests: Declarations Competing interests RPM travel grants from Accord, BMS, MSD, lecture fees from BMS, GSK, Novartis, Roche; AD travel grants and lecture fees from Roche, BMS, Janssen, Molteni, MSD, Accord; ŁS travel grants from BMS, Accord; AD travel grants and lecture fees from BMS, MSD, Astellas, Merck, Servier, Astra Zeneca, Pfizer; JD travel grants and lecture fees from Amgen, AstraZeneca, BMS, MSD, Novartis, Nutricia; AGW travel grants and lecture fees from Roche, Novaris, Lili, Astellas, Pfizer, Amgen, Swixx, Pierre Fabre, Egis, BMS, MSD; AR travel grants and lecture fees from Roche, BMS, Ipsen, Pfizer, Novartis, Gilead, MSD; DTM travel grants and lecture fees from MSD, Pierre Fabre, BMS, Novartis, Pfizer; JW no declared; PB travel grants, lecture fees, and advisory boards from AstraZeneca, MSD, GSK, Pharma; MP travel grants and lecture fees from AstraZeneca, Roche, Novartis, Elli Lilly, Janssen, Gilead and Amgen; Ethical approval The study protocol was approved by the Bioethics Committee of Jagiellonian University Medical College (decision number 118.0043.1.115.2024 dated April 19, 2024).

Purpose: The prevalence of type 2 diabetes mellitus (T2DM) in cancer patients is high. During the medication review process, clinical pharmacists could detect and manage drug-related problems (DRP) to optimize pharmacotherapy but there is a need to standardize pharmacists' interventions (PI) especially for T2DM-related DRP. The present study aims to describe DRP in cancer patients with T2DM undergoing anticancer treatment (AT) and to propose related preliminary guidelines to manage T2DM-related DRP., Methods: The study was conducted in one oncology outpatient hospital where a clinical pharmacy team performs medication reviews to detect and manage DRP by performing PI in cancer patients undergoing AT. All the data from November 23rd, 2015 to November 23rd, 2019 were extracted and demographic, clinical, oncological, and biological data were collected and analyzed. Based on these results and a literature review, a working group (2 pharmacists and one diabetologist) was constituted to propose a first set of preliminary guidelines clinical pharmacists that were then reviewed using the Delphi method by an expert panel of oncologists and pharmacists., Results: A total of 161 T2DM cancer patients were included in the study (19.7% of all cancer patients screened). Overall, 152 DRP (mean 1.67/patient) were detected (49.3% drug interaction) and 152 PI were performed by clinical pharmacists, mainly drug monitoring (48.0) and drug discontinuation (25.7%). Specifically, there was 24 T2DM-related DRP (including 29.2% drug interactions). Twenty-four DRPs were directly related to T2DM status. The five proposed guidelines reached a consensus after revisions and a sixth has been added., Conclusion: DRPs were frequent among cancer patients with T2DM and we hypothesize that the preliminary guidelines should improve the detection of DRPs directly related to T2DM. The implementation of the preliminary guidelines should now be assessed in clinical practice., Competing Interests: Declarations Ethics approval The study was conducted in accordance with the Helsinki declaration. Patients’ records were anonymized prior to analysis. A database from ONCOPTIMAL (F20220817142044) was created in accordance with the reference methodology MR004 of the National Commission of Liberties and Informatics (no. MR00414012022). As per French regulations about retrospective study, no informed consent and additional ethical committee review were required.

Immunotherapy with PD-1 or PD-L1 inhibitors has become an essential treatment strategy for a growing number of malignancies. These treatments have a risk for immune-related adverse events (IRAEs). Pooled analyses based on clinical trials show a favorable toxicity profile for treatment with PD-L1 compared to PD-1 inhibitors. This study aimed to investigate differences in IRAEs between patients with advanced solid malignances treated with PD-L1 and PD-1 inhibitors in a real-world setting. We conducted a retrospective cohort study at four Swedish Regions. Patients (n = 605) treated for advanced cancer with a PD-L1 or PD-1 inhibitor in monotherapy between June 2016 and August 2022 were included. Non-small cell lung cancer (NSCLC) was the most common malignant disease (n = 251; 41.5%), followed by malignant melanoma (n = 173; 28.6%), renal cell carcinoma (n = 71; 11.7%) and urothelial carcinoma (n = 35; 5.8%). Among patients receiving PD-L1 inhibitors, NSCLC (94.4%) was the predominant malignancy, whereas for those treated with PD-1 inhibitor, malignant melanoma constituted the most prevalent malignancy (34.5%). Discontinuation of treatment due to IRAEs overall and IRAEs grade ≥ 2 were significantly less common in patients treated with PD-L1 compared to PD-1 inhibitors [Odds Ratio (OR): 0.38 (95% Confidence Interval (CI) 0.16-0.88) and OR: 0.63 (95% CI 0.35-0.98) respectively]. Any grade IRAE, IRAE grade ≥ 3 and multiple IRAEs were numerically more frequent in patients treated with PD-1 inhibitors.In conclusion, our study of patients with advanced solid malignancies in a real-world setting supports the results from clinical trials demonstrating a favorable toxicity profile for PD-L1 inhibitors versus PD-1 inhibitors., (© 2024.

Background: Immune-related adverse events (irAEs) pose substantial challenges in the realm of cancer immunotherapy, frequently affecting treatment efficacy and patient safety. To address the urgent need for identifying risk factors associated with irAEs, we conducted a comprehensive phenotype-wide Mendelian randomization analysis (MR-PheWAS)., Methods: Utilizing publicly accessible genome-wide association study (GWAS) data, this investigation evaluated the impact of over 5000 exposure variables on susceptibility to irAEs using univariate Mendelian randomization (MR). We categorized these correlations and further explored potential mechanisms by which associated traits might influence irAEs through multivariate MR., Results: MR-PheWAS identified numerous risk factors for irAEs, encompassing both previously documented and novel associations. Specifically, we identified 105 traits with probable causal relationships to all-grade irAEs and 119 traits with suggestive associations. For high-grade irAEs, we categorized 122 traits as probably associated and 141 as suggestively associated. Notably, multivariate MR analyses uncovered intricate interactions, particularly highlighting how diabetes impacts all-grade irAEs through mediators such as body mass index and sex hormone-binding globulin., Conclusions: This study has not only identified new risk factors for irAEs but also confirmed several well-established ones. Further investigation is crucial to validate and assess these identified risk factors within clinical trials. A mechanistic understanding of these causal factors is essential for improving the management and prevention of irAEs., (© 2024. The Author(s).)

The NCCN Guidelines for the Management of Immunotherapy-Related Toxicities are intended to provide oncology practitioners with guidance on how to manage the wide-ranging and potentially fatal toxicities that may occur with cancer immunotherapy. The guidelines address immune-related adverse events related to immune checkpoint inhibitors, CAR T-cell therapies, and lymphocyte engagers (which include T-cell-engaging bispecific antibodies). These NCCN Guidelines Insights highlight recent guideline updates pertaining to the management of emerging toxicities related to cancer immunotherapy.

Background/aim: Immune-related adverse events (irAEs) occur in various organs, and sometimes multiply following treatment with immune checkpoint inhibitors (ICIs). This study aimed to determine the association between the number of irAEs and clinical outcomes., Patients and Methods: This was a retrospective study that included patients with lung cancer, melanoma, and head and neck cancer who were treated with anti-programmed cell death (ligand) 1 (PD-1/PD-L1) monotherapy. We evaluated the association between the number of irAEs and progression-free survival (PFS) in the simple Cox regression analysis. To eliminate the immortal-time bias, an additional landmark analysis was performed., Results: In total, 92, 69, and 37 patients were allocated to the no, single, and multisystem irAEs groups, respectively. The multisystem irAEs were associated with better PFS compared to the no irAE group. In contrast, at the 12-week landmark, multisystem irAEs were associated with poor PFS compared to the no irAEs group. Furthermore, the rate of treatment suspension owing to irAEs in the multisystem irAEs group (62.5%) was higher than that in the single irAE group (17.3%) at the 12-week landmark., Conclusion: The incidence of multisystem irAEs was associated with improved clinical outcomes in patients with lung cancer, melanoma, and head and neck cancer treated with PD-1/PD-L1 inhibitor monotherapy. However, these results may be influenced by a potential immortal-time bias. When accounting for this bias, the early development of multisystem irAEs within 12 weeks was linked to treatment suspension and poorer clinical outcomes., (Copyright © 2024, International Institute of Anticancer Research (Dr. George J.

Purpose: Randomized controlled trials with tirzepatide (TZP) displayed unprecedented glucose and body weight lowering efficacy in individuals with type 2 diabetes and/or obesity and a safety profile similar to that of glucagon-like peptide-1 receptor agonists (GLP-1RA), mainly characterized by gastrointestinal (GI) adverse events (AE). Concerns on diabetic retinopathy, pancreato-biliary disorders, and medullary thyroid cancer were also addressed. We aimed to investigate whether the same safety issues emerged from the FDA Adverse Event Reporting System (FAERS) post-marketing surveillance database., Methods: OpenVigil 2.1-MedDRA-v24 and AERSMine (data 2004Q1-2023Q3) were used to query the FAERS database. Reports of GI AE, diabetic retinopathy, pancreato-biliary disorders, and medullary thyroid cancer were investigated. The analysis was then filtered for age, gender, and designation as primary suspect. AE occurrence with TZP was compared to insulin, sodium-glucose cotransporter-2 inhibitors, metformin, and GLP-1RA., Results: Disproportionate reporting of GI [i.e., nausea (ROR 4.01, 95% CI 3.85-4.19)] and pancreato-biliary disorders [i.e., pancreatitis (ROR 3.63, 95% CI 3.15-4.19)], diabetic retinopathy (ROR 4.14, 95% CI 2.34-7.30), and medullary thyroid cancer (ROR 13.67, 95% CI 4.35-42.96) was detected. TZP exhibited a similar risk of GI AE and medullary thyroid cancer and a lower risk of most pancreato-biliary AE and diabetic retinopathy vs. GLP-1RA., Conclusions: TZP was associated with an increased risk of specific AE. However, its safety profile was similar to that of GLP-1RA, without increased risk of pancreato-biliary AE, diabetic retinopathy, and medullary thyroid cancer., (© 2024. The Author(s).)

Background: The current guidelines for treating metastatic castration-sensitive prostate cancer (mCSPC) recommend treatment intensification of androgen deprivation therapy (ADT) with the addition of an androgen receptor pathway inhibitor (ARPI), with or without docetaxel. However, the adoption of these treatment options has been slow, leading to therapeutic inertia. This real-world study was conducted to investigate the occurrence of adverse events (AEs) among treated patients diagnosed with mCSPC in the United States., Methods: This retrospective claim review estimated the occurrence of AEs among patients with mCSPC from January 2014 to June 2021 in the PharMetrics® Plus data set. The study focused on 10 common AEs (fatigue/asthenia, gastrointestinal [GI] AEs, skin/nail/hair AEs, immunodeficiency/thrombocytopenia, hot flash, sexual function AEs, anemia, hypertension, pain, and edema) known to occur in ≥10% of patients and ≥2% more prevalent than those treated with ADT alone as selected from the US Food and Drug Administration prescribing information and published results from clinical trials. Proportions of patients experiencing these AEs at Day 90, 180, and then every 180 days until month 30 during the follow-up period were estimated using cumulative hazard plots. Results were adjusted using inverse probability of treatment weighting (IPTW) across four treatment groups: ADT alone, ADT + nonsteroidal anti-androgen (NSAA) (bicalutamide, nilutamide, or flutamide), ADT + docetaxel, and ADT + ARPIs (abiraterone, apalutamide, or enzalutamide). ADT-alone cohort was the reference group for all comparisons., Results: A total of 4145 patients were included (ADT alone: 2318, ADT + NSAA: 632, ADT + docetaxel: 471, ADT + ARPIs: 724). At baseline, median (interquartile range [IQR]) age was 64.3 (60.1-73.1) years; most common sites of metastasis were bone only (n = 1886, 45.5%) and node only (n = 1237, 29.8%); most used medications were pain medications (n = 2182, 52.6%) and corticosteroids (n = 1213, 29.3%). Median (IQR) duration of follow-up 10.2 (6.1-16.6) months in ADT alone, 6.7 (4.1-11.5) months in ADT + NSAA, 5.1 (4.3-5.9) months in ADT + docetaxel, and 11.0 (6.6-17.0) months in ADT + ARPI cohort. The reported AEs increased over time for all assessed AEs, across all treatment groups. Compared with ADT alone, no statistically significant difference in the proportion of patients with AEs was seen in the ADT + ARPI or ADT + NSAA cohorts at months 3 and 12; a significantly higher proportion of patients in the ADT + docetaxel cohort experienced 6 of the 10 assessed AEs at month 3 (fatigue/asthenia, GI AEs, skin/nail/hair AEs, immunodeficiency/thrombocytopenia, hot flash, anemia). During the follow-up period, on IPTW analysis, compared with ADT alone, a significantly higher proportion of patients experienced AEs with seven AEs in the ADT + docetaxel group (fatigue/asthenia, GI AEs, skin/nail/hair AEs, immunodeficiency/thrombocytopenia, hot flash, anemia, edema; p < 0.001 for all seven), three AEs in the ADT + ARPI group (hot flash, p = 0.05; anemia, p = 0.01; edema, p = 0.019), and one AE in the ADT + NSAA group (anemia, p = 0.029). The proportion of patients with sexual function AE did not significantly differ between the treatment groups and ADT alone., Conclusion: Results of this large, real-world study demonstrated that all treatment groups experienced an increase in the rates of AEs over time, including ADT alone. Most AE rates with ADT + ARPIs were comparable with ADT + NSAA and not significantly different from ADT alone. ADT + docetaxel cohort was associated with significantly higher rates for all AEs over time except hypertension, sexual dysfunction, and pain. This study provides real-world evidence on AEs, beyond controlled clinical trials, and may assist healthcare providers to make better-informed decisions about disease management among patients with mCSPC., (© 2024 The Author(s).

While some literature has provided limited information about the potential cardiovascular risk and immune-related adverse events (irAEs) risk associated with PD-1/PD-L1 inhibitors in the treatment of Head and Neck Squamous Cell Carcinoma (HNSCC), the exact relevance is still uncertain. To assess the pharmacovigilance (PV), constituent ratio, severity, and reaction outcomes of major adverse cardiovascular events (MACE) and immune-related adverse events (irAEs) related to PD-1/PD-L1 inhibitors for HNSCC reported to the United States Food and Drug Administration Adverse Event Reporting System (FAERS). We analyzed reports of cardiovascular adverse events and irAEs associated with drug therapy for HNSCC submitted to FAERS from the 1st quarter 2015 to the 3rd quarter of 2023. Three PD-1/PD-L1 inhibitors were identified: nivolumab, pembrolizumab and durvalumab. Our primary composite endpoint was the PV of MACE and irAEs related to PD-1/PD-L1 inhibitors in the treatment of HNSCC, and the secondary endpoint was PV of other cardiovascular events. The software implemented was STATA 17.0 MP. 19,372 suspected drug-adverse event reports related to drug treatment in patients with HNSCC were identified, of which 916 reports were cardiovascular events, including 555 reports of MACE and 361 reports of other cardiovascular events. The PV signal regarding MACE was detected in durvalumab (PRR  = 2.12, 95% CI: 1.24-3.61; χ2  = 7.71; ROR  = 2.19, 95% CI: 1.24-3.86; IC  = 1.01; IC025  = 0.07) but not in nivolumab and pembrolizumab. The constituent ratio of MACE in all adverse events caused by nivolumab (OR  = 0.38, 95% CI: 0.19-0.73) and pembrolizumab (OR  = 0.48, 95% CI: 0.23-0.99) was significantly decreased, compared with durvalumab. A PV signal about other cardiovascular events was detected in durvalumab (PRR  = 3.04, 95% CI: 1.73-5.31; χ2  = 16.13; ROR  = 3.15, 95% CI: 1.74-5.70; IC  = 1.46; IC025  = 0.48), but it was not detected in nivolumab or pembrolizumab. The constituent ratio of other cardiovascular events in all adverse events caused by nivolumab (OR  = 0.25, 95% CI: 0.13-0.48) and pembrolizumab (OR  = 0.40, 95% CI: 0.20-0.80) was significantly decreased, compared with durvalumab. The constituent ratio of other cardiovascular events in all adverse events caused by nivolumab (OR  = 0.61, 95% CI: 0.38-0.99) was significantly decreased, compared with pembrolizumab. There were 40 cases of hypertension. A PV signal about hypertension was detected in pembrolizumab (PRR  = 3.72, 95% CI: 1.87-7.43; χ2  = 15.99; ROR  = 3.75, 95% CI: 1.87-7.51; IC  = 1.53, IC025  = 0.45), but it was not detected in nivolumab. The constituent ratio of hypertension in all adverse events caused by nivolumab (OR  = 0.09, 95% CI: 0.09-0.39) was significantly decreased, compared with pembrolizumab. There were 737 cases of irAEs. A PV signal about irAEs was detected in nivolumab (PPR  = 1.27, 95% CI: 1.05-1.53; χ2  = 6.38; ROR  = 1.28, 95% CI: 1.06-1.56; IC  = 0.29, IC025  = -0.00) and pembrolizumab (PPR  = 2.20, 95% CI: 1.79-2.71; χ2  = 56.55; ROR  = 2.31, 95% CI: 1.84-2.88; IC  = 1.03; IC025  = 0.68), but it was not detected in durvalumab. The constituent ratio of irAEs in all adverse events caused by nivolumab (OR  = 0.58, 95% CI: 0.44-0.76) significantly decreased, compared with pembrolizumab. By comparing the PV signals, constituent ratio, severity, and reaction outcome of the three drugs, we suppose that nivolumab can be used as the safest PD-1/PD-L1 inhibitor for HNSCC., (© 2024.

Background: Understanding the risk relationship between statin use and immune-related adverse events (irAEs) in patients undergoing immune checkpoint inhibitors (ICIs) therapy is crucial for optimizing oncological management., Objective: This study aimed to investigate whether the use of statins increases the risk of irAEs in patients receiving ICI therapy., Methods: This study primarily utilized data from FAERS database. Multivariable logistic regression was the principal method of analysis, and the Benjamini-Hochberg procedure was employed to adjust for multiple hypothesis testing., Results: In a group of 145,214 patients undergoing ICI therapy, 9,339 reported using statin medications. Multivariable analysis indicated an increased risk of irAEs among statin users (OR 1.199, 95% CI: 1.141-1.261; FDR p < 0.001) in comparison to those not using statins. Notably, increased risks were observed particularly in patients diagnosed with lung, pancreatic, and renal cancers. The link between statin usage and increased irAEs risk remained consistent across various ICIs treatments., Conclusions: Statin medication usage is linked to an elevated probability of experiencing irAEs in patients enrolled in ICI therapy. In cancer patients receiving immune checkpoint inhibitors, careful consideration of statin use is essential to avoid potentially increased irAEs risk. These findings provide critical guidance for clinicians in developing treatment strategies that balance therapeutic efficacy and safety in oncological management., Competing Interests: Author RH was employed by Hangzhou Linan Guorui Health Industry Investment Co., Ltd.

The concept of time toxicity in oncology refers to the presence of frequent healthcare-related interactions that can interfere with patient well-being. In this review, we examine several manifestations of time toxicity in non-Hodgkin lymphoma and multiple myeloma and discuss their impact on decision-making with patients. For example, time toxicity may influence the choice of chemoimmunotherapy versus lenalidomide-rituximab in follicular lymphoma. In myeloma, it may inform the optimal dosing schedule for proteasome inhibitors and bisphosphonates. In both malignancies, varying time toxicity profiles are a key distinction between chimeric antigen receptor T-cell therapies and bispecific antibodies. We outline the challenges with measuring time toxicity as a trial endpoint but discuss its importance as a consideration for patient care, both in standard-of-care settings and in clinical trials. Throughout the review, we highlight strategies to lower the time toxicity of therapies in lymphoma and myeloma without compromising their efficacy or patient safety.

Introduction: The development of immune checkpoint inhibitors (ICIs) represents one of the most significant advancements in cancer treatment over the past decade. Nivolumab, a widely used ICI, has been incorporated into the therapeutic regimens for various cancers. As with any drug, this drug also has side effects, including class-specific immune-related adverse effects (irAEs). Although irAEs are not rare, their diagnosis can be challenging. This study examines the emergency department (ED) visits of patients undergoing nivolumab therapy, focusing on diagnostic challenges, evaluating the management, and outcomes of irAEs in the ED setting., Material and Methods: A retrospective cohort study was conducted on adult patients who received nivolumab therapy for any cancer between April 1, 2018, and March 31, 2023, at a large, urban tertiary care center. In this study, we evaluated the ED visits of patients receiving nivolumab. In addition to previous studies, we evaluated irAEs in detail (percentage, recognizability, risk factors, reasons for late recognition, and outcome). Patient data were collected from electronic medical records and patient's medical files. The anamnesis, laboratory, and imaging results, ED management, and consultation notes were examined separately for each ED visit. Logistic regression models were employed to identify significant univariable predictors of ED visits and irAEs., Results: A total of 199 patients were included in the study, all of whom had metastatic cancer. Of these, 154 patients (77.4%) received nivolumab therapy for non-small cell lung cancer. Most patients (71.9%, n = 143) had at least one additional comorbidity. One hundred and eleven patients (55.8%) presented to the ED. Hypertension (OR: 2.425, 95% CI: 1.226-4.795, p = 0.011) and chronic obstructive pulmonary disease (OR: 2.489, 95% CI: 1.133-5.468, p = 0.023) were identified as risk factors for ED visits. A total of 21 irAEs were diagnosed (14 in ED, 6 in the oncology clinic, and 1 in the inpatient ward). Univariate analysis found no significant association between irAE diagnosis and any specific factors., Conclusion: A significant proportion of the patients treated with nivolumab for advanced cancer present to ED for ICI-related adverse events, although most cases were not attributable to irAEs. Due to the vague symptomatology of irAEs, their recognition and diagnosis in the ED can be challenging. Close collaboration between ED physicians and oncologists is paramount to the management of patients with cancer in the ED., (© 2024.

Immune checkpoint inhibitors have revolutionized cancer treatment by targeting the cytotoxic T lymphocyte antigen-4 and programmed death-1/ligand-1. Although immune checkpoint inhibitors show promising therapeutic efficacy, they often cause immune-related adverse events. Immune-related adverse events differ from the side effects of conventional chemotherapy and require vigilant monitoring. These events predominantly affect organs, such as the colon, liver, lungs, pituitary gland, thyroid and skin, with rare cases affecting the heart, nervous system and other tissues. As immune-related adverse events result from immune activation, indicating the reinvigoration of exhausted immune cells that attack both tumors and normal tissues, it is theoretically possible that immune-related adverse events may signal a better response to immune checkpoint inhibitor therapy. Recent retrospective studies have explored the link between immune-related adverse event development and clinical efficacy; however, the predictive value of immune-related adverse events in the immune checkpoint inhibitor response remains unclear. Additionally, studies have focused on immune-related adverse events, timing of onset and immunosuppressive treatments. This review focuses on pivotal studies of the association between immune-related adverse events and outcomes in patients treated with immune checkpoint inhibitors., (© The Author(s) 2024.

Background: This study aimed to summarize the occurrence of immune-related adverse events (irAEs) and further evaluate their association with clinical outcomes in patients with advanced renal cell carcinoma (RCC) and urothelial carcinoma (UC) treated with immune checkpoint inhibitors (ICIs)., Methods: A comprehensive search of PubMed, Embase, and the Cochrane Library up to December 2023 was conducted to identify eligible studies. The details of irAEs and data regarding their correlation with clinical outcomes were extracted. R software was used for meta-analysis., Results: A total of 27 studies involving 6148 patients with RCC or UC were included. The pooled overall incidence for any-grade and grade ≥ 3 irAEs was 44.2 % (95 % CI: 38.1 %-50.5 %) and 15.7 % (95 % CI: 11.4 %-21.1 %), respectively. Compared to those without any irAEs, patients with irAEs showed improved PFS (HR = 0.44, 95 % CI: 0.35-0.56, p < 0.01) and OS (HR = 0.47, 95 % CI: 0.42-0.51, p < 0.01), as well as higher ORR (OR = 3.59, 95 % CI: 3.01-4.29, p < 0.01) and DCR (OR = 4.23, 95 % CI: 3.06-5.84, p < 0.01). Subgroup analysis indicated that clinical outcome improvements were associated with the occurrence of irAEs, regardless of tumor type or ICI agent. Notably, patients with cutaneous irAEs, thyroid dysfunction, and grade ≤ 2 irAEs had a higher probability to achieve better survival benefits from ICI-based therapy, while pulmonary irAEs and grade ≥ 3 irAEs seemed to have a negative impact on OS. Additionally, systemic glucocorticoids administration did not affect survival outcomes., Conclusion: Our findings suggest that the occurrence of irAEs could be considered as a potential prognostic factor for predicting the efficacy of ICIs in patients with advanced RCC and UC., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Aims: This systematic review aimed to investigate the occurrence of moderate and severe adverse drug reactions (ADRs) to antimicrobials among hospitalized children., Methods: The PubMed/Medline, Cochrane Library, Embase, Web of Science, Scopus, Lilacs and CINAHL databases were searched in April 2023 to systematically review the published data describing the characteristics of moderate and severe ADRs to antimicrobials among hospitalized children. The search was carried out without date restrictions, up to the search date (April, 2023)., Results: At the end of the selection process, 30 articles met the inclusion criteria. Cutaneous reactions were the primary serious clinical manifestations in most articles (19/30), followed by erythema multiforme (71 cases), Stevens-Johnson syndrome (72 cases), and toxic epidermal necrolysis (22 cases). The main antimicrobials involved in moderate and severe ADRs were penicillins, cephalosporins and sulfonamides. Regarding the primary outcomes, 30% (9/30) of the articles reported deaths, and 46.7% (14/30) of studies reported increased lengths of hospital stay, need for intensive care, and transfer to another hospital. Regarding the main interventions, 10% (3/30) of the articles mentioned greater monitoring, suspension, medication substitution or prescription of specific medications for the symptomatology., Conclusions: The findings of this review could be used to identify areas for improvement and help health professionals and policymakers develop strategies. In addition, we emphasize the importance of knowing about ADRs so that there is adequate management to avoid undesirable consequences., (© 2024 British Pharmacological Society.)

Purpose: This study aims to investigate the underexplored prevalence of placebo-reported immune-related adverse events (irAEs) in immune checkpoint inhibitor (ICI) trials., Methods: We searched public databases for randomized clinical trials (RCTs) involving ICI versus placebo treatments in patients with malignancies. Study characteristics and irAEs occurrences were extracted for meta-analyses using a random-effects model., Main Outcomes: Proportions of patients reported to experience any grade and grade 3 to 5 placebo irAEs; the risk ratio (RR) of reporting 'false' irAEs in the experiment arm (defined as 'false-irAE ratio', calculated by dividing the proportion of patients documented with irAEs in the placebo arm by that in the experimental arm)., Results: 47 RCTs with 30,119 patients were analyzed. The pooled proportion of patients reported to experience any grade and grade 3 to 5 irAEs among placebo participants was 22.85 % (17.33 %-29.50 %) and 3.40 % (2.35 %-4.63 %), respectively. The pooled proportion of placebo-treated patients who experienced serious irAEs was 0.67 % (0.03 %-1.91 %). Treatment discontinuation and death due to placebo irAEs occurred in 0.69 % (<0.01 %-1.30 %) and 0.12 % (<0.01 %-0.40 %) of patients, respectively. The false-irAE ratio for any grade and grade 3 to 5 irAEs were 0.49 and 0.28. The false-irAE ratio was significantly higher in RCTs with control arms of placebo plus non-immunotherapy than in those with placebo alone (any grade: 0.57 vs. 0.32, P < 0.001; grade 3 to 5: 0.36 vs. 0.12, P = 0.009)., Conclusion: Our analyses of placebo-treated participants in ICI RCTs document the common occurrence of placebo irAEs. These findings are important for interpreting irAE profiles, avoiding inappropriate therapeutic interventions., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objectives: The use of immune checkpoint inhibitors (ICIs) as anticancer therapy across a variety of malignancies has led to durable efficacy in a subset of patients. However, associated side effects denoted immune-related adverse events (irAEs) have emerged and can result in substantial morbidity and mortality. Particularly early in the experience of using these agents, a lack of standardized education regarding irAEs among patients and clinical providers may have contributed to poor outcomes. Optimal management of these emerging toxicities depends on a coordinated institutional approach. We hypothesized that centralized educational programs and electronic health record (EHR)-based interventions, targeted both toward ICI-treated patients as well as patient-interfacing providers, would improve patient outcomes., Methods: We created a multidisciplinary team of clinicians and associated staff to direct a coordinated approach to the education and management of patients receiving ICIs across our institution. A 3-tiered approach was designed: patient-centered, internally centered, and externally centered. Multimedia educational products were produced for patients to improve knowledge and awareness of ICIs and associated irAEs. An EHR-based banner was deployed to improve identification of patients receiving ICIs across disciplines. Tailored educational seminars were provided to clinicians who interact with ICI-treated patients at all levels. Educational seminars were also offered to local physicians and institutions. We assessed patient uptake of educational products and surrogate patient outcomes to measure the potential impact of our interventions., Results: Fox Chase Cancer Center (FCCC)-specific ICI identification cards were created and distributed to patients. By the end of the investigational period, 98.6% of ICI-treated patients reported receiving a card. An ICI-focused on-line portal was created accessible only to ICI-treated patients, with 9.4% of these patients accessing the portal in the first 6 months without marketing promotion. Deidentified surrogate clinical endpoints of corticosteroid use, direct referral unit (DRU) visits, and hospital admissions all improved during the study period., Conclusions: Institutionally directed educational initiatives are feasible at a free-standing academic cancer center and may lead to improved outcomes in patients developing irAEs from ICIs. More granular patient-specific data and studies at other types of institutions are necessary to determine the applicability of similar approaches on a broader scale., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Patients with breast cancer experience various types of adverse events (AEs) during their treatment journey. We aimed to evaluate the incidence, characteristics, and impact of serious AEs in breast cancer patients receiving antineoplastic treatment in the ambulatory setting. A 4-month prospective observational study that included patients with breast cancer treated in the chemotherapy infusion clinics. Patients were assessed for serious AEs, defined as any AE that resulted in a visit to the emergency department (ED) with or without hospital admission, or required any clinical intervention, which were considered as the addition of supportive medications or modifications to the treatment protocol. Characteristics of the patients and antineoplastic regimens as well as the type of AEs were recorded. During the study period, 1168 patients received 2547 cycles. The mean age was 50 ± 11.6 (SD) years and patients had received a median (IQR) of 3 (1-5) treatment cycles prior to enrollment. Among the study cohort, 465 patients(40%) developed at least one serious AE. A total of 660 (26%) cycles were associated with 757 AEs, which required ED visits, addition of supportive medications, and modifications to the treatment protocol in 58%, 29%, and 17% of the cycles, respectively. Most common AEs were musculoskeletal (n = 132, 17%) and gastrointestinal (n = 125, 16.5%). Taxane-based regimens were associated with the most AEs (n = 286, 38%). In a cohort of patients with breast cancer treated in the ambulatory setting, 4 out of 10 patients developed at least one serious AE during the study period. Future research should identify measures to reduce the incidence and severity of such complications., (© 2024 The Author(s).

Introduction: Patients with chronic kidney disease (CKD) are at increased risk of developing tuberculosis (TB). These patients may also be at higher risk of developing antitubercular treatment (ATT)-associated adverse drug reactions (ADRs). Although dose modification has been recommended, data regarding the impact of impaired kidney function on ATT-associated ADRs is sparse. We studied the incidence and profile of ATT-associated ADRs in patients with CKD and compared them with those with normal kidney function., Methodology: This retrospective study analyzed all patients initiated on ATT from January 2016 to August 2019. Patients were grouped into CKD and normal kidney function based on their eGFR. Data on ATT-associated ADRs were collected from medical records. Predictors of ADRs were assessed using univariable and multivariable logistic regression. Additionally, Propensity score matching and analysis were done for CKD and normal kidney function in 1:3 ratio., Results: Of 1815 patients on ATT, 75 (4.1%) had CKD. ADRs were more frequent [36/75 (48.0%) vs. 239/1740 (13.7%), p  ≤ 0.0001] and more severe [15/46 (32.6%) vs. 43/283 (15.1%), p  = 0.010] in CKD than those with normal kidney function. The most common ADRs were hepatobiliary [23/75 (30.6%) vs. 156/1740 (8.9%), p  ≤ 0.0001], neuropsychiatric [8/75(10.6%) vs. 21/1740(1.2%), p  ≤ 0.0001], renal [4/75(5.3%) vs. 8/1740(0.4%), p  = 0.001], and gastrointestinal [5/75(6.6%) vs. 34/1740 (1.9%), p  = 0.020]. CKD was an independent predictor for ADRs (OR -4.96, 95% CI: 2.79-8.82; p  ≤ 0.0001). The matched cohort showed similar results., Conclusion: ATT-associated ADRs were more common and severe in patients with CKD, despite drug dose modifications. Optimal dosing of ATT in CKD needs to be further evaluated.

Background: Chagas disease (CD) is a serious public health problem in Latin America. Benznidazole (BNZ) is used for the treatment of CD and, despite its wide use, little information is available about its toxicity and mechanisms of adverse drug reactions (ADR)., Objectives: To identify and classify clinical and laboratory adverse reactions caused by BNZ in terms of causality and severity., Methods: Prospective cohort study from January 2018 to December 2021. Treatment follow-up included visits and biochemical tests (complete blood count, liver and kidney function tests) before, during and after treatment. ADR were classified according to causality and severity. In the statistical analysis, the significance level was set at p<0.05., Results: Forty patients with chronic CD were included. A high prevalence of ADR was observed 161 ADR in 30 patients [90%]; of these, 104 (64.6%) were classified as possible and 57 (35.4%) as probable. The ADR were classified as moderate and mild. Of the 40 patients, nine (22.5%) discontinued treatment. ADR associated with treatment discontinuation and interventions were those that affected the dermatological system, central and peripheral nervous system and sense organs such as ageusia. Mild hematological and biochemical changes such as lymphopenia were observed after 30 days of treatment., Conclusion: Many patients were able to complete the treatment even with ADR, which can be attributed to the successful follow-up strategy with symptomatic treatment and counseling, leading to patient's awareness of symptoms and treatment adherence.

Objectives: Polypharmacy, drug-drug interactions (DDI) and related adverse drug reaction (ADR) are understudied in SSc. The aim of this work was to determine the prevalence and determinants of DDI and ADR in a real-life prospective cohort of SSc patients., Methods: We performed a retrospective analysis of the drug prescriptions of SSc patients admitted to the daily scleroderma clinic between January 2020 and April 2022. DDI were identified using 2 prescription analysis applications, and adjudicated related ADRs occurring during a one-year follow-up were reported. Risk factors for DDI and ADR were identified using multivariate analysis., Results: One hundred and eight SSc patients were included. The median number of medications per patient was 6 [4-9]. Seventy-one (65.7 %) patients had 5 or more medications, and 23 (21.3 %) had 10 or more. Seventy-two (66.7 %) patients had DDIs on their prescriptions at inclusion. Patients with DDIs had more medications than patients without DDIs (7 [5-10] versus 3 [2-5], p < 0.0001). Six (8.3) patients experienced ADRs during the one-year follow-up. Patients with ADRs had more medications (14 [10-18] versus 7 [5-10] p < 0.001) and more DDIs (12 [7-32] versus 3 [1-6]; p < 0.001) than patients without ADRs. Multivariate analysis confirmed that the number of prescribed medications was independently positively associated with DDIs (OR: 2.25 [1.52-3.32], p < 0.0001) as well as with ADRs (OR: 1.68 [1.17-2.40], p < 0.01)., Conclusions: SSc patients are significantly exposed to polypharmacy, DDIs and related ADRs, particularly in cases of severe illness, and especially if 5 or more medications are prescribed., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Background: Immune-checkpoint inhibitors (ICIs) often cause immune-related adverse events (irAEs). The spectrum of irAEs and their managements has been partially clarified, however the knowledge on time-course of irAEs is not well understood., Methods: A retrospective study based on the medical record was performed. The study subjects were consisting of patients with various types of solid tumors for whom ICIs (nivolumab, pembrolizumab, durvalumab, atezolizumab, nivolumab plus ipilimumab) were used between April 2016 and October 2021. We focused on irAEs developed more than 1-year after commencement ICIs (delayed irAE group) and compared with irAEs developed within 1-year (non-delayed irAE group) in terms of types and severity of irAEs., Results: A total of 336 patients were enrolled in the study. Eighty-eight patients (26.2%) developed irAEs and 248 did not. Most of the patients developing irAEs were treated using PD-L1/PD-1 inhibitors. Eighty-one patients (24.1%) in non-delayed irAE group and 7 patients (2.1%) in delayed irAE group developed irAEs. The median onset of irAEs in the delayed irAE group was 18.6 months (range: 13.5-24.3). The types of irAEs observed in delayed irAE group were dermatitis (2 cases), pneumonitis (2 cases), nephritis (1 case), arthritis (1 case), and gastritis (1 case). The severity of irAEs was almost mild (≤G2), but one patient (.3%) developed G3 nephritis., Conclusion: PD-L1/PD-1 inhibitors frequently caused various irAEs but their severities were mostly tolerable. Few patients developed delayed irAE with mild toxities., (© 2024 John Wiley & Sons Australia, Ltd.)

Purpose: Toxicity is a significant problem among women receiving systemic chemotherapy for breast cancer, with up to 60% experiencing hematologic and 14% experiencing non-hematologic toxicity. Chemotherapy is dosed using body surface area, which does not account for heterogeneity in lean body mass (LBM) and adipose tissue (AT). This systematic review, registered with the PROSPERO International Prospective Register of Systematic Reviews (#CRD42021279874), evaluates associations between body composition and chemotherapy-related toxicity during breast cancer treatment., Methods: Scientific literature databases (PubMed, Scopus, CINAHL, and CENTRAL) were systematically searched in November 2021 for studies evaluating associations between body composition (assessed using computed tomography or dual x-ray absorptiometry) and chemotherapy-related toxicity among women receiving breast cancer treatment. Eligibility was not limited by year or country of publication. Article screening and data abstraction was conducted using the Covidence Systematic Review Management System. Predetermined criteria were used to evaluate rigor of participant recruitment, representativeness of the population, and use of validated measures of body composition and toxicity., Results: An inverse association between LBM and toxicity was reported in seven of the eight included studies, although definitions of low LBM differed across studies. Three studies evaluated the association between AT and chemotherapy toxicity with inconsistent findings. Heterogeneity in body composition measures/definitions and treatment regimens precluded the ability to perform meta-analyses., Conclusion: Low LBM appears to be a risk factor for chemotherapy toxicity, but the role of AT is unclear., Implications for Cancer Survivors: Further research that accounts for guideline concordance in chemotherapy prescriptions and the use of supportive care medications is needed., (© 2023.

Objective: To explore the characteristics of adverse drug reactions during the 24-week therapy with delamanid-containing regimen for patients with multidrug-resistant and rifampicin-resistant pulmonary tuberculosis (MDR/RR-PTB). Methods: The prospective multicenter study was conducted from June 2020 to June 2023. A total of 608 eligible patients with MDR/RR-PTB were enrolled in 26 tuberculosis medical institutions in China including 364 males and 79 females, aged 39.6(19.0-68.0) years. Patients were treated with chemotherapy regimens containing delamanid. Patients were closely supervised during treatment of medication, and all adverse reactions occurring during treatment were monitored and recorded. The clinical characteristics of adverse reactions were evaluated by descriptive analysis. Chi-square test and multivariate logistic regression were used to analyze the related factors of QTcF interval prolongation (QT corrected with Fridericia's formula). Results: Of the 608 patients enrolled in this study, 325 patients (53.5%) reported 710 adverse events within 24 weeks of treatment. The top 6 most common complications were hematological abnormalities (143 patients, 23.5%), QT prolongation (114 patients, 18.8%), liver toxicity (85 patients, 14.0%), gastrointestinal reaction (41 patients, 6.7%), peripheral neuropathy (25 patients, 4.1%) and mental disorders (21 patients, 3.5%). The prolongation of QT interval mostly occurred in the 12th week after the first dose of medication. Serious adverse reactions occurred in 21 patients (3.5%). There were 7 patients (1.2%) with mental disorders, including 2 patients (0.3%) with severe mental disorders. Conclusions: The safety of dalamanid-based regimen in the staged treatment of MDR/RR-PTB patients was generally good, and the incidence of adverse reactions was similar to that reported in foreign studies. This study found that the incidence of QT interval prolongation in Chinese patients was higher than that reported overseas, suggesting that the monitoring of electrocardiogram should be strengthened when using drugs containing delamanid that may cause QT interval prolongation.

Immune checkpoint inhibitors (ICIs) have transformed cancer treatment, improving outcomes for many patients. However, toxicities termed immune-related adverse events (irAEs) are limitations of these revolutionary treatments. These irAEs may resolve with treatment or ICI cessation (acute) or persist many months beyond therapy cessation (chronic). Acute irAEs were the first to be recognized and are thus more well studied. However, chronic irAEs have been highlighted in recent years and are becoming a topic of more intensive investigation. These chronic irAEs have been noted to affect many different organ systems, including endocrine, rheumatologic, gastrointestinal, dermatologic, neurologic, and cardiovascular systems. In this review, we discuss current knowledge surrounding the frequency, time course, and risk factors associated with chronic irAEs affecting various organ systems, treatment approaches, and future directions., Competing Interests: Competing interests: DBJ has served on advisory boards or as a consultant for BMS, Mallinckrodt, Merck, Mosaic ImmunoEngineering, Novartis, Oncosec, Pfizer, Targovax, and Teiko, and has received research funding from BMS and Incyte., (© Author(s) (or their employer(s)) 2024.

Background: Fatigue is an immune-related adverse event (irAE) associated with immune checkpoint inhibitors (ICIs) used for cancer treatment. Chinese herbal medicines (Ho-zai) are used to treat cancer-related fatigue. However, no interactions between ICIs and Ho-zai have been reported. Herein, we investigated the risk of irAEs associated with the concomitant use of ICIs and Ho-zai., Methods: We extracted data of patients who used ICI and Ho-zai from the Japanese Adverse Event Reporting Database. The proportional reporting ratio (PRR) was calculated for patients using ICI, Ho-zai, or both. We focused on cases of interstitial lung disease (ILD) and colitis, which were among the most severe cases of irAEs among these patients. The shrinkage method used by the World Health Organization-Uppsala Monitoring Center was used to detect the interactions., Results: Of the 799,670 patients in the database, 77,219, 2060, and 92 were using ICIs, Ho-zai, and combination treatment, respectively. The ILD and colitis groups included 39,388 and 17,522 patients, respectively. ILD signals were detected for both ICIs and Ho-zai. There were 24 cases of patients treated with concomitant ICIs and Ho-zai who developed ILD. For all combinations of all ICIs and all Ho-zai, Ω025 was negative, which suggested no ILD-related interactions. Colitis signals were detected for ICIs except for atezolizumab, avelumab, and durvalumab. There were eight patients treated with concomitant ICI and Ho-zai who developed colitis. For all combinations of all ICIs and all Ho-zai, Ω025 was negative, which suggested no colitis-related interactions., Conclusion: To our knowledge, this is the first study to investigate interactions between ICIs and Ho-zai. Signals were detected for ILD in both ICI and Ho-zai groups, and colitis in the ICI group. However, the combined use of these treatments did not increase the risk of irAEs.

Purpose: The association between immune-related adverse events (irAEs) and survival outcomes in non-small cell lung cancer (NSCLC) patients treated with programmed death-(ligand) 1 [PD-(L)1] inhibitors remains controversial, partly due to variations in dealing with immortal-time bias (ITB)., Materials and Methods: We retrospectively enrolled 425 advanced NSCLC patients who received anti-PD-(L)1 monotherapy between January 2016 and June 2021, stratifying them into irAE (n=127) and non-irAE (n=298) groups. The primary endpoint was to assess the impact of irAEs on progression-free survival (PFS) and overall survival (OS). Landmark (2-, 3-, 6-, and 9-month) and time-dependent Cox analyses were performed to eliminate ITB., Results: With a median follow-up of 38.8 months, the occurrence of overall irAEs was significantly associated with superior PFS (11.2 vs. 3.4 months, p < 0.001) and OS (31.4 vs. 14.0 months, p < 0.001), which persisted in landmark and time-dependent Cox analyses. For the main organ-specific irAEs, skin, thyroid, and hepatic irAEs, respectively, showed significantly improved survival compared to the non-irAE group, whereas pneumonitis did not. Single-organ irAEs had the best outcomes compared with multi-organ or no irAE, which also held across subgroups of skin, thyroid, and hepatic irAEs. Moreover, severe grade irAEs and immunotherapy discontinuation had a detrimental effect on survival, systemic steroid therapy showed little effect, while immunotherapy resumption had tolerable safety and a trend of improved survival., Conclusion: After adequately adjusting ITB, the occurrence of overall irAEs predicts for favorable efficacy of anti-PD-(L)1 monotherapy in NSCLC, with better outcomes observed in patients with skin, thyroid, or hepatic irAEs, particularly those with single-organ involvement.

Background: Immune checkpoint blockers (ICBs) can induce immune-related adverse events (irAEs) whose management is based on expert opinion and may require the prescription of steroids and/or immunosuppressants (ISs). Recent data suggest that these treatments can reduce the effectiveness of ICBs., Objective: To investigate the relationship between the use of steroids and/or ISs and overall survival (OS) and progression-free survival (PFS) among ICB-treated patients with an irAE., Methods: We prospectively collected data from the medical records of patients with solid tumors or lymphoma in the French REISAMIC cohort and who had been treated with ICBs between June 2014 and June 2020., Results: 184 ICB-treated patients experienced at least one Common Terminology Criteria for Adverse Events grade ≥ 2 irAE. 107 (58.2%) were treated with steroids alone, 20 (10.9%) with steroids plus IS, 57 (31.0%) not received steroids or IS. The median OS was significantly shorter for patients treated with steroids alone (25.2 months [95% confidence interval (CI): 22.3-32.4] than for patients treated without steroids or IS (63 months [95%CI: 40.4-NA]) and those receiving an IS with steroids (53.4 months [95%CI: 47.3-NA]) (p < 0.001). The median PFS was significantly shorter for patients treated with steroids alone (17.0 months [95%CI: 11.7-22.9]) than for patients treated without steroids or IS (33.9 months [95%CI: 18.0-NA]) and those receiving an IS with steroids (41.1 months [95%CI: 26.2-NA]) (p = 0.006). There were no significant intergroup differences in the hospital admission and infection rates., Conclusion: In a prospective cohort of ICB-treated patients, the use of IS was not associated with worse OS or PFS, contrasting with the use of steroids for the management of irAEs., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objective: Antibody-drug conjugates (ADC), enfortumab-vedotin (EV) and sacituzumab-govitecan are new drugs in the treatment of urologic tumors, whose safety profile has not been fully investigated. Therefore, the aim of our study was to evaluate adverse events related to both agents reported to VigiBase, the World Health Organization's global pharmacovigilance database., Methods: We employed Bayesian disproportionality analysis based on the information component (IC) to explore the safety profile associated with both therapies. Additionally, we used the proportional reporting ratio approach to examine the safety profile further., Results: We identified 41,752 reports connected to ADC therapy (EV: n=5359; SG: n=36,393). In the EV subgroup, most reports were associated with dermatologic (38.6%), neurologic adverse events (16.5%), or adverse laboratory assessments (19.4%). In contrast, reports in the SG subgroup were mainly associated with gastrointestinal adverse events (24.2%) and adverse laboratory assessments (39.0%). Adverse laboratory assessments in both cohorts were often based on haematotoxic adverse events., Conclusion: We could provide a comprehensive real-world safety profile of EV and SG using a global pharmacovigilance database. Based on the safety signals explored in this study, further research regarding the impact of these side effects on patient outcomes is justified., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: FR receives research funding from Janssen.

Nonclinical studies involve in vitro, in silico, and in vivo experiments to assess the toxicokinetics, toxicology, and safety pharmacology of drugs according to regulatory requirements by a national or international authority. In this review, we summarize the potential effects of various underlying diseases governing the absorption, distribution, metabolism, and excretion (ADME) of drugs to consider the use of animal models of diseases in nonclinical trials. Obesity models showed alterations in hepatic metabolizing enzymes, transporters, and renal pathophysiology, which increase the risk of drug-induced toxicity. Diabetes models displayed changes in hepatic metabolizing enzymes, transporters, and glomerular filtration rates (GFR), leading to variability in drug responses and susceptibility to toxicity. Animal models of advanced age exhibited impairment of drug metabolism and kidney function, thereby reducing the drug-metabolizing capacity and clearance. Along with changes in hepatic metabolic enzymes, animal models of metabolic syndrome-related hypertension showed renal dysfunction, resulting in a reduced GFR and urinary excretion of drugs. Taken together, underlying diseases can induce dysfunction of organs involved in the ADME of drugs, ultimately affecting toxicity. Therefore, the use of animal models of representative underlying diseases in nonclinical toxicity studies can be considered to improve the predictability of drug side effects before clinical trials., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

The study aims to estimate the incidence and risk factors of adverse drug reactions (ADRs) induced by anti-tuberculosis (TB) drugs. A single center retrospective analysis of patients taking anti-TB therapy from January 2016 to December 2018 in the hospital was conducted. Univariate and multivariate logistic regression analysis were used to identify these risk factors of ADRs induced by anti-TB drugs. Among 1430 patients receiving anti-TB therapy, 440 (30.77%) patients showed at least 1 ADR induced by anti-TB drugs. Hyperuricemia was the most common ADR, followed by hepatic function test abnormality, liver damage and gastrointestinal reactions. Significant differences (P < .05) were also seen in diabetes, age, treatment duration, type of TB (extrapulmonary) and some therapeutic regimens between ADR group and non-ADR group, respectively. Multivariate logistic regression analysis showed that treatment duration (OR = 1.029, 95%CI[1.018-1.040], P = .000), type of TB (extrapulmonary, OR = 1.487, 95%CI[1.134-1.952], P = .004) and some therapeutic regimens (HREZ, OR = 1.425, 95%CI[0.922-2.903], P = .001; HRZS, OR = 2.063, 95% CI[1.234-3.449], P = .006; HRZ, OR = 3.623, 95%CI[2.289-5.736], P = .000) were risk factors for ADRs induced by anti-TB drugs. Anti-TB drugs usually induced the occurrence of severe and frequent adverse effects, such as hyperuricemia. Treatment duration, HREZ, HRZS and HRZ regimens, and type of TB (extrapulmonary) should be considered as high-risk factors. Thus, it should be recommended to consider optimum management during anti-TB therapy, particularly hyperuricemia monitoring and hepatic function test., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: Immuno-oncology (IO) drugs are essential for treating various cancer types; however, safety concerns persist in older patients. Although the incidence of immune-related adverse events (irAEs) is similar among age groups, higher rates of hospitalization or discontinuation of IO therapy have been reported in older patients. Limited research exists on IO drug safety and risk factors in older adults. Our investigation aimed to assess the incidence of irAEs and identify the potential risk factors associated with their development., Methods: This retrospective analysis reviewed the clinical data extracted from the medical records of patients aged > 80 years who underwent IO treatment at our institution. Univariate and multivariate analyses were performed to assess the incidence of irAEs., Results: Our study included 181 patients (median age: 82 years, range: 80-94), mostly men (73%), with a performance status of 0-1 in 87% of the cases; 64% received IO monotherapy. irAEs occurred in 35% of patients, contributing to IO therapy discontinuation in 19%. Our analysis highlighted increased body mass index, eosinophil counts, and albumin levels in patients with irAEs. Eosinophil count emerged as a significant risk factor for any grade irAEs, particularly Grade 3 or higher, with a cutoff of 118 (/μL). The group with eosinophil counts > 118 had a higher frequency of irAEs, and Grade 3 or higher events than the group with counts ≤ 118., Conclusion: IO therapy is a safe treatment option for patients > 80 years old. Furthermore, patients with elevated eosinophil counts at treatment initiation should be cautiously managed., (© 2024. The Author(s).)

Background: Immune checkpoint inhibitors (ICI) induce adverse events (irAEs) that do not respond to steroids, i.e. steroid-refractory (sr) irAEs, and irAEs in which steroids cannot be tapered, i.e. steroid-dependent (sd) irAEs, in about 10% of cases. An evidence-based analysis of the effectiveness of second-line immunosuppressive agents with regard to irAE and tumor control is lacking., Methods: The international web-based Side Effect Registry Immuno-Oncology (SERIO; http://serio-registry.org) is a collaborative initiative with the Paul-Ehrlich-Institute to document rare, severe, complex or therapy-refractory immunotherapy-induced side effects. The registry was queried on August 1, 2023 for cases of irAEs which were treated with second-line therapies., Results: From a total of 1330 cases, 217 patients (16.3%) received 249 second-line therapies. A total of 19 different second-line therapies were employed, including TNF-alpha antagonists (46.5%), intravenous immunoglobulins (IVIG; 19.1%), mycophenolate mofetil (15.9%), and methotrexate (3.6%). Therapy choices were determined by the type of irAE. The time to onset of sr-/sd-irAEs after ICI initiation did not consistently differ from steroid-responsive irAEs. While 74.3% of sr-/sd-irAEs resolved and 13.1% had improved, 4.3% persisted, 3.9% resulted in permanent sequelae, and 4.3% in death with ongoing symptoms. Infliximab exhibited potential for earlier symptom improvement compared to mycophenolate mofetil or IVIG. Tumor response in patients with second-line treated sd-/sr-irAE was similar to patients with irAEs treated with steroids only., Conclusion: Several second-line therapies are effective against sr-/sd-irAEs, the second-line therapies show no clear negative impact on tumor response, and infliximab shows potential for faster improvement of symptoms. However, prospective comparative data are needed., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests., (Copyright © 2024 The Authors.

Introduction: Sotorasib is a first-in-class KRASG12C inhibitor that showed significant clinical activity in KRAS G12C -mutated non-small cell lung cancer (NSCLC). The most frequent grade 3 or 4 sotorasib-related adverse events (AEs) were diarrhea (4-12 %) and hepatotoxicity (10.1-15.1 %). Data is lacking about the management of these AEs, especially in patients receiving sequential anti-PD-(L)1 and sotorasib therapy. Our aim was to report the management of grade ≥ 2 sotorasib-related AEs in real-world setting and to propose practical guidance for the management of grade ≥ 2 sotorasib-related AEs and more generally KRASG12C inhibitors-related AEs., Materials and Methods: Records from all consecutive patients who initiated sotorasib through expanded access program in two French anti-cancer centers from January 1st 2021 to April 1st 2023 were reviewed to identify and grade sotorasib-related AEs, according to NCI-CTCAE v5.0., and to collect AEs management data. Patients were included in the analysis if they presented a grade ≥ 2 sotorasib-related AE., Results: From 57 patients identified, 21 met inclusion criteria including eighteen (86 %) who received sequential anti-PD-(L)1 and sotorasib therapy. Hepatotoxicity (76 %) and diarrhea (24 %) were the most common grade ≥ 2 sotorasib-related AEs. Among the 16 patients with a grade ≥ 2 hepatotoxicity, 12 (75 %) definitely discontinued sotorasib, among which 9 (56 %) after dose reductions and rechallenge, and five (32 %) received corticosteroids, allowing only one patient to resume sotorasib. Diarrhea and nausea were usually manageable and not associated with sotorasib discontinuation. We propose a step-by-step management practical guidance for sotorasib-related hepatotoxicity based on dose-reduction and careful monitoring. Liver biopsy is strongly encouraged for grade 3 and 4 hepatotoxicity to assess candidates for corticosteroids., Discussion: The experience with sotorasib might help better prevent, screen and manage sotorasib-related and other KRASG12C inhibitors-related AEs, particularly hepatotoxicity., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Ali Chour (ali.chour@chu-lyon.fr) reported no disclosures.

Purpose: We present and validate a rule-based algorithm for the detection of moderate to severe liver-related immune-related adverse events (irAEs) in a real-world patient cohort. The algorithm can be applied to studies of irAEs in large data sets., Methods: We developed a set of criteria to define hepatic irAEs. The criteria include: the temporality of elevated laboratory measurements in the first 2-14 weeks of immune checkpoint inhibitor (ICI) treatment, steroid intervention within 2 weeks of the onset of elevated laboratory measurements, and intervention with a duration of at least 2 weeks. These criteria are based on the kinetics of patients who experienced moderate to severe hepatotoxicity (Common Terminology Criteria for Adverse Events grades 2-4). We applied these criteria to a retrospective cohort of 682 patients diagnosed with hepatocellular carcinoma and treated with ICI. All patients were required to have baseline laboratory measurements before and after the initiation of ICI., Results: A set of 63 equally sampled patients were reviewed by two blinded, clinical adjudicators. Disagreements were reviewed and consensus was taken to be the ground truth. Of these, 25 patients with irAEs were identified, 16 were determined to be hepatic irAEs, 36 patients were nonadverse events, and two patients were of indeterminant status. Reviewers agreed in 44 of 63 patients, including 19 patients with irAEs (0.70 concordance, Fleiss' kappa: 0.43). By comparison, the algorithm achieved a sensitivity and specificity of identifying hepatic irAEs of 0.63 and 0.81, respectively, with a test efficiency (percent correctly classified) of 0.78 and outcome-weighted F1 score of 0.74., Conclusion: The algorithm achieves greater concordance with the ground truth than either individual clinical adjudicator for the detection of irAEs.

Objectives: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of non-small cell lung cancer (NSCLC). However, the application of ICIs can also cause treatment-related adverse events (trAEs) and immune-related adverse events (irAEs). This study was to evaluate both the irAEs and trAEs of different ICI strategies for NSCLC based on randomized clinical trials (RCTs). The study also examined real-world pharmacovigilance data from the Food and Drug Administration Adverse Event Reporting System (FAERS) regarding claimed ICI-associated AEs in clinical practice., Methods: Based on Pubmed, Embase, Medline, and the Cochrane CENTRAL, we retrieved RCTs comparing ICIs with chemotherapy drugs or with different ICI regimens for the treatment of NSCLC up to October 20, 2023. Bayesian network meta-analysis (NMA) was performed using odds ratios (ORs) with 95% credible intervals (95%CrI). Separately, a retrospective pharmacovigilance study was performed based on FAERS database, extracting ICI-associated AEs in NSCLC patients between the first quarter (Q1) of 2004 and Q4 of 2023. The proportional reports reporting odds ratio was calculated to analyze the disproportionality., Results: The NMA included 51 RCTs that involved a total of 26,958 patients with NSCLC. Based on the lowest risk of any trAEs, cemiplimab, tislelizumab, and durvalumab were ranked as the best. Among the agents associated with the lowest risk of grades 3-5 trAEs, tislelizumab, avelumab, and nivolumab were most likely to rank highest. As far as any or grades 3-5 irAEs are concerned, atezolizumab plus bevacizumab plus chemotherapy is considered the most safety option. However, it is associated with a high risk of grades 3-5 trAEs. As a result of FAERS pharmacovigilance data analysis, 9,420 AEs cases have been identified in 7,339 NSCLC patients treated with ICIs, and ICIs were related to statistically significant positive signal with 311 preferred terms (PTs), and comprehensively investigated and identified those AEs highly associated with ICIs. In total, 152 significant signals were associated with Nivolumab, with malignant neoplasm progression, death, and hypothyroidism being the most frequent PTs., Conclusion: These findings revealed that ICIs differed in their safety profile. ICI treatment strategies can be improved and preventive methods can be developed for NSCLC patients based on our results., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Liang, Xiao, Li, Chen and Li.)

Background: Immune checkpoint inhibitors (ICIs) have significantly improved outcomes in various cancers. ICI treatment is associated with the incidence of immune-related adverse events (irAEs) which can affect any organ. Data on irAEs occurrence in relation to sex- differentiation and their association with gender-specific factors are limited., Aims: The primary objective of the G-DEFINER study is to compare the irAEs incidence in female and male patients who undergo ICI treatment. Secondary objectives are: to compare the irAEs incidence in pre- and postmenopausal female patients; to compare the irAEs incidence in female and male patients according to different clinical and gender-related factors (lifestyle, psychosocial, and behavioral factors). Exploratory objectives of the study are to compare and contrast hormonal, gene-expression, SNPs, cytokines, and gut microbiota profiles in relation to irAEs incidence in female and male patients., Methods and Results: The patients are recruited from Fondazione IRCCS Istituto Nazionale dei Tumori, Italy, St Vincent's University Hospital, Ireland, Oslo University Hospital, Norway, and Karolinska Insitutet/Karolinska University Hospital, Sweden. The inclusion of patients was delayed due to the Covid pandemic, leading to a total of 250 patients recruited versus a planned number of 400 patients. Clinical and translational data will be analyzed., Interpretation: The expected outcomes are to improve the management of cancer patients treated with ICIs, leading to more personalized clinical approaches that consider potential toxicity profiles. The real world nature of the trial makes it highly applicable for timely irAEs diagnosis.

Serious hematological adverse drug reactions (HADRs) may lead to or prolong hospitalization and even cause death. The aim of this study was to determine the regulatory factors associated with HADRs caused by drugs that were authorized up to July 2023 by the European Medicines Agency (EMA) and to evaluate the frequency of HADRs. Using a cross-sectional approach, the type and frequency of HADRs were collected from the Summaries of Product Characteristics of Drugs Authorized by the EMA and analyzed within proprietary, nonproprietary, and biosimilar/biological frameworks. Multivariate statistical analysis was used to investigate the associations of generic status, biosimilar status, conditional approval, exceptional circumstances, accelerated assessment, orphan drug status, years on the market, administration route, and inclusion on the Essential Medicines List (EML) with HADRs. In total, 54.78% of proprietary drugs were associated with HADRs at any frequency, while anemia, leucopenia, and thrombocytopenia were observed in approximately 36% of the patients. The predictors of any HADR, anemia, and thrombocytopenia of any frequency are generic status, biosimilar status, and inclusion on the EML, while the only protective factor is the administration route. Biosimilars and their originator biologicals have similar frequencies of HADRs; the only exception is somatropin. Knowledge of the regulatory factors associated with HADRs could help clinicians address monitoring issues when new drugs are introduced for the treatment of patients., (© 2024. The Author(s).)

Purpose: Combination therapies are a promising approach for improving cancer treatment, but it is challenging to predict their resulting adverse events in a real-world setting., Experimental Design: We provide here a proof-of-concept study using 15 million patient records from the FDA Adverse Event Reporting System (FAERS). Complex adverse event frequencies of drugs or their combinations were visualized as heat maps onto a two-dimensional grid. Adverse event frequencies were shown as colors to assess the ratio between individual and combined drug effects. To capture these patterns, we trained a convolutional neural network (CNN) autoencoder using 7,300 single-drug heat maps. In addition, statistical synergy analyses were performed on the basis of BLISS independence or χ2 testing., Results: The trained CNN model was able to decode patterns, showing that adverse events occur in global rather than isolated and unique patterns. Patterns were not likely to be attributed to disease symptoms given their relatively limited contribution to drug-associated adverse events. Pattern recognition was validated using trial data from ClinicalTrials.gov and drug combination data. We examined the adverse event interactions of 140 drug combinations known to be avoided in the clinic and found that near all of them showed additive rather than synergistic interactions, also when assessed statistically., Conclusions: Our study provides a framework for analyzing adverse events and suggests that adverse drug interactions commonly result in additive effects with a high level of overlap of adverse event patterns. These real-world insights may advance the implementation of new combination therapies in clinical practice., (©2024 The Authors; Published by the American Association for Cancer Research.)

Nearly half of the deaths among hospitalized human immuno deficiency virus-infected patients in the highly active antiretroviral therapy era have been attributed to liver disease. This may range from an asymptomatic mild increase of liver enzymes to cirrhosis and liver failure. Different works of literature elucidated both retroviral infection and the adverse effects of highly active antiretroviral therapy as a cause of hepatotoxicity. Individual adaptations to medications and environmental exposures, shaped by cultural norms and genetic predispositions, could potentially modulate the risk and progression of liver disease in this population. Therefore, this study aims to assess the predictors of severe hepatotoxicity in retroviral-infected adults receiving highly active antiretroviral therapy regimens within the Ilubabor Zone, Southwest Ethiopia. A facility-based cross-sectional study was conducted among adult retroviral-infected patients in five selected anti-retro virus therapy clinics from May1 to July 30/2022. A systematic sampling technique was used to select 457 study participants and Binary logistic regression statistical data analysis was used, P value < 0.05 was considered statistically significant. The prevalence of severe hepatotoxicity was 21.44% in the study population. CD +4 count < 200 cells/mm 3 (AOR = 2.19, 95% CI 1.04-5.22, P = 0.01), human immunodeficiency virus co-infection with tuberculosis (AOR = 2.82, 95% CI 1.01-8.29, P = 0.03) and human immuno deficiency virus co-infection with hepatitis-B/hepatitis C virus (AOR = 5.02, 95% CI 1.82-16.41) were predictors of severe hepatotoxicity. The magnitude of severe hepatotoxicity was high among adult retroviral-infected patients on highly active anti-retroviral drug regimens. Co-infection of human immuno deficiency virus with hepatitis B virus or hepatitis C virus, tuberculosis and CD4 + T-cell count below 200 cells/mm 3 were predictors of severe hepatotoxicity. Therefore, HIV patients on highly active antiretroviral therapy require close attention and regular monitoring of their liver function., (© 2024. The Author(s).)

Background: The study aimed to evaluate the agreement of prescribed drug dosages with renal dosing recommendations and describe adverse drug events (ADEs) contributing to hospital admissions of patients with chronic kidney disease (CKD)., Methods: This cross-sectional study focused on CKD patients admitted to University Hospital Hradec Králové, with an estimated glomerular filtration rate below 60 ml/min. The necessity for renal dosage adjustments was determined using the Summary of Product Characteristics (SmPC). For medications requiring renal dosage adjustment according to SmPC, agreement between the prescribed and recommended renal dosage was assessed. ADEs were adjudicated using the OPERAM drug-related hospital admissions adjudication guide., Results: Of 375 CKD patients, 112 (30%, 95% CI 25-34) were prescribed drug dosages in disagreement with SmPC renal dosage recommendations. Perindopril, metformin, and ramipril were most frequently dosed in disagreement with SmPC. ADE-related hospital admissions occurred in 20% (95% CI 16-24) of CKD patients., Conclusion: CKD patients are often prescribed medication dosages in disagreement with SmPC renal dosing recommendations. Besides explicit factors, treatment goals, feasibility of monitoring and alternative treatment must be weighed when assessing drug and dosage appropriateness. Gastrointestinal bleeding was the most frequent ADE that contributed to hospital admissions of CKD patients.

Purpose: Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, yet their use is associated with immune-related adverse events (irAEs). Estimating the prevalence and patient impact of these irAEs in the real-world data setting is critical for characterizing the benefit/risk profile of ICI therapies beyond the clinical trial population. Diagnosis codes, such as International Classification of Diseases codes, do not comprehensively illustrate a patient's care journey and offer no insight into drug-irAE causality. This study aims to capture the relationship between ICIs and irAEs more accurately by using augmented curation (AC), a natural language processing-based innovation, on unstructured data in electronic health records., Methods: In a cohort of 9,290 patients treated with ICIs at Mayo Clinic from 2005 to 2021, we compared the prevalence of irAEs using diagnosis codes and AC models, which classify drug-irAE pairs in clinical notes with implied textual causality. Four illustrative irAEs with high patient impact-myocarditis, encephalitis, pneumonitis, and severe cutaneous adverse reactions, abbreviated as MEPS-were analyzed using corticosteroid administration and ICI discontinuation as proxies of severity., Results: For MEPS, only 70% (n = 118) of patients found by AC were also identified by diagnosis codes. Using AC models, patients with MEPS received corticosteroids for their respective irAE 82% of the time and permanently discontinued the ICI because of the irAE 35.9% (n = 115) of the time., Conclusion: Overall, AC models enabled more accurate identification and assessment of patient impact of ICI-induced irAEs not found using diagnosis codes, demonstrating a novel and more efficient strategy to assess real-world clinical outcomes in patients treated with ICIs.

With immune checkpoint inhibitors (ICIs) becoming the mainstay of treatment for many cancers, managing their immune-related adverse events (irAEs) has become an important part of oncological care. This Review covers the clinical presentation of irAEs and crucial aspects of reversibility, fatality and long-term sequelae, with special attention to irAEs in specific patient populations, such as those with autoimmune diseases. In addition, the genetic basis of irAEs, along with cellular and humoral responses to ICI therapy, are discussed. Detrimental effects of empirically used high-dose steroids and second-line immunosuppression, including impaired ICI effectiveness, call for more tailored irAE-treatment strategies. We discuss open therapeutic challenges and propose potential avenues to accelerate personalized management strategies and optimize outcomes., (© 2024. Springer Nature America, Inc.)

Background: Anti-disialoganglioside (anti-GD2) monoclonal antibodies are effective immunotherapeutic drugs for treating neuroblastoma, yet their toxicity spectrum is unclear., Objective: This study aimed to assess the toxicity profiles of three anti-GD2 monoclonal antibodies (dinutuximab, dinutuximab β, and naxitamab) in clinical applications by mining and evaluating the adverse drug reaction (ADR) signals from the US Food and Drug Administration Adverse Event Reporting System., Methods: Data in the US Food and Drug Administration Adverse Event Reporting System from the time anti-GD2 monoclonal antibodies became available in the market to the first quarter of 2023 were searched. The signals of anti-GD2 monoclonal antibody-associated ADRs were quantified using four types of algorithms, including the reporting odds ratio, the proportional reporting ratio, the combination of the proportional reporting ratio and χ 2 statistic method used by the UK Medicines and Healthcare Products Regulatory Agency, and the Bayesian confidence propagation neural network. The ADRs were categorized by System Organ Class based on the Medical Dictionary for Regulatory Activities, and were sorted according to the frequency and signal strength of ADRs., Results: A total of 370 adverse drug event reports with anti-GD2 monoclonal antibodies listed as the 'primary suspected drugs' were identified, with 116 ADR signals detected, of which 22 were not in the drug labels. Among the adverse drug event reports, 276 reports concerned dinutuximab/dinutuximab β as primary suspected drugs with 90 ADR signals, involving 19 System Organ Classes, of which 21 signals were not in the label; 94 adverse drug event reports concerned naxitamab as the primary suspected drug with 26 ADR signals, involving 11 System Organ Classes, of which one was not in the label. For dinutuximab/dinutuximab β-related ADRs, the top five most frequent were "fever", "abdominal pain", "elevated aspartate aminotransferase (AST)", "elevated alanine aminotransferase (ALT)" and "hypotension"; the top five most intensive signals were "hypoalbuminemia", "elevated AST", "capillary leakage syndrome", "hypoxia" and "elevated ALT". For naxitamab-related ADRs, the top five most frequent were "hypotension", "pain", "urticarial", "hypertension" and "rash"; the top five most intensive signals were "hypotension", "urticaria", "hypoxemia", "bronchospasm" and "hypertension". Involved System Organ Classes included "investigations" and "respiratory, thoracic and mediastinal disorders" containing the most types of ADR signals in dinutuximab/dintuximab β-related ADRs and naxitamab-related ADRs, respectively., Conclusions: Our study comprehensively analyzed the toxicity profiles of anti-GD2 monoclonal antibodies and provides an important reference for clinical monitoring and ADR identification of these drugs., (© 2023.

Background: We aimed to characterize newer antiseizure medications (ASMs)-induced hepatotoxicity in children and identify signals of disproportionate reporting of hepatotoxicity-related adverse drug events (ADEs)., Research Design and Methods: Case reports reported to VigiBase were accessed using Empirica™ Signal software. To summarize characteristics of the retrieved cases, descriptive statistics were used. A disproportionality analysis was conducted using the Multi-item Gamma Poisson Shrinker algorithm, which calculates Empirical Bayesian Geometric Mean value and its lower and upper 95% confidence limits (EB05 and EB95, respectively). EB05 > 2, N  > 0 was considered a signal., Results: Based on 870 analyzed cases, a higher proportion of cases was reported in girls than in boys and in patients aged 2-11 years than in other age groups. Most cases were serious. In 25 cases, hepatotoxicity resulted in death. A high proportion of patients ( n  = 275, 31.61%) experienced hypersensitivity reactions, mostly due to lamotrigine. The disproportionality analysis yielded 17 signals concerning felbamate, lamotrigine, levetiracetam, oxcarbazepine, stiripentol, and topiramate. Four signals were for severe liver injury and concerned felbamate, lamotrigine, levetiracetam, and topiramate. Gender-biased reporting frequency was detected for four ASM-ADE combinations., Conclusion: Our results should serve to raise clinicians' awareness about the potential association between several newer ASMs and drug-induced liver injury in children.

Background: Pharmacogenomics (PGx) holds promise to revolutionize modern healthcare. Although there are several prospective clinical studies in oncology and cardiology, demonstrating a beneficial effect of PGx-guided treatment in reducing adverse drug reactions, there are very few such studies in psychiatry, none of which spans across all main psychiatric indications, namely schizophrenia, major depressive disorder and bipolar disorder. In this study we aim to investigate the clinical effectiveness of PGx-guided treatment (occurrence of adverse drug reactions, hospitalisations and re-admissions, polypharmacy) and perform a cost analysis of the intervention., Methods: We report our findings from a multicenter, large-scale, prospective study of pre-emptive genome-guided treatment named as PREemptive Pharmacogenomic testing for preventing Adverse drug REactions (PREPARE) in a large cohort of psychiatric patients (n = 1076) suffering from schizophrenia, major depressive disorder and bipolar disorder., Findings: We show that patients with an actionable phenotype belonging to the PGx-guided arm (n = 25) present with 34.1% less adverse drug reactions compared to patients belonging to the control arm (n = 36), 41.2% less hospitalisations (n = 110 in the PGx-guided arm versus n = 187 in the control arm) and 40.5% less re-admissions (n = 19 in the PGx-guided arm versus n = 32 in the control arm), less duration of initial hospitalisations (n = 3305 total days of hospitalisation in the PGx-guided arm from 110 patients, versus n = 6517 in the control arm from 187 patients) and duration of hospitalisation upon readmission (n = 579 total days of hospitalisation upon readmission in the PGx-guided arm, derived from 19 patients, versus n = 928 in the control arm, from 32 patients respectively). It was also shown that in the vast majority of the cases, there was less drug dose administrated per drug in the PGx-guided arm compared to the control arm and less polypharmacy (n = 124 patients prescribed with at least 4 psychiatric drugs in the PGx-guided arm versus n = 143 in the control arm) and smaller average number of co-administered psychiatric drugs (2.19 in the PGx-guided arm versus 2.48 in the control arm. Furthermore, less deaths were reported in the PGx-guided arm (n = 1) compared with the control arm (n = 9). Most importantly, we observed a 48.5% reduction of treatment costs in the PGx-guided arm with a reciprocal slight increase of the quality of life of patients suffering from major depressive disorder (0.935 versus 0.925 QALYs in the PGx-guided and control arm, respectively)., Interpretation: While only a small proportion (∼25%) of the entire study sample had an actionable genotype, PGx-guided treatment can have a beneficial effect in psychiatric patients with a reciprocal reduction of treatment costs. Although some of these findings did not remain significant when all patients were considered, our data indicate that genome-guided psychiatric treatment may be successfully integrated in mainstream healthcare., Funding: European Union Horizon 2020., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 The Author(s).

Aim: There are discrepancies between the information patients desire about adverse drug reactions (ADRs) and the information they receive from healthcare providers; this is an impediment to shared decision-making. This study aimed to establish whether patients received information about ADRs resulting from prescribed pharmacotherapy, before hospital discharge, after percutaneous coronary intervention (PCI) and to determine whether receiving information about ADRs was associated with incidence of self-reported ADRs or concerns related to prescribed pharmacotherapy., Methods: CONCARD PCI , a prospective multicentre cohort study including 3,417 consecutive patients after PCI, was conducted at seven high-volume referral PCI centres in two Nordic countries. Clinical data were collected from patients' medical records and national quality registries. Patient-reported outcome measures were registered 2 months (T1), 6 months (T2), and 12 months (T3) after discharge. Covariate-adjusted logistic regression yielded adjusted odds ratios (aORs) with 95% confidence intervals (CIs)., Results: At discharge, 38% of participants had been informed about potential ADRs. For these patients, the incidence of self-reported ADRs was significantly lower at T1 (aOR 0.61, 95% CI 0.50-0.74; p<0.001), T2 (aOR 0.60, 95% CI 0.49-0.74; p<0.001), and T3 (aOR 0.57, 95% CI 0.46-0.71; p<0.001). Those who were not informed reported higher levels of concern about prescribed pharmacotherapy at all measuring points (p<0.001 for all comparisons). Those living alone (aOR 0.73, 95% CI 0.57-0.92; p=0.008), who were female (aOR 0.57, 95% CI 0.44-0.72; p<0.001), and with three or more versus no comorbidities (aOR 0.61, 95% CI 0.44-0.84; p=0.002) were less likely to receive information., Conclusion: A substantial proportion of patients were not informed about potential ADRs from prescribed pharmacotherapy after PCI. Patients informed about ADRs had lower incidences of self-reported ADRs and fewer concerns about prescribed pharmacotherapy., Competing Interests: Conflict of Interest None., (Copyright © 2023 The Author(s).

Background: Migraine has a high prevalence in the population and accounts for 12% of primary headaches. Ubrogepant is used for the treatment of acute migraine, and although some clinical trials have demonstrated the safety of Ubrogepant, its long-term safety in a large sample of the population remains to be investigated., Methods: We collected data from the US Food and Drug Administration Adverse Event Reporting System (FAERS) database. We used reporting odds ratio (ROR), the proportional reporting ratio (PRR), the information component (IC) and the empirical Bayes geometric mean (EBGM) to evaluate Ubrogepant-induced adverse events (AEs)., Results: We screened out 2,067 reports of Ubrogepant as primary suspected (PS) and 6,190 reports of Ubrogepant-induced AEs as PS. Our results showed that Ubrogepant-induced AEs targeted 4 system organ classes (SOCs), detected 32 Preferred terms (PTs) signals in 9 SOCs, including common Ubrogepant label consistent with Migraine, Nausea, Somnolence, Paraesthesia oral and Dizziness, It also includes the AEs of Hemiparesis, Mental impairment, Dysstasia, Tinnitus, Chest pain, Cold sweat, Neck pain, etc. that have not been demonstrated in previous studies., Conclusions: Our study identified new AEs that have not been reported, which provides a new guidance to deepen the comprehension of the safety of Ubrogepant.
