INTRODUCTION: Niraparib first-line maintenance (1LM) therapy has demonstrated clinical benefit for patients with ovarian cancer (OC) in clinical trial and real-world settings, but data on factors associated with real-world patient outcomes remain limited. This analysis identified patient characteristics associated with time to next treatment (TTNT), a proxy for real-world progression-free survival, in patients with OC treated with 1LM niraparib monotherapy. METHODS: This retrospective observational study used a USA nationwide electronic health record-derived deidentified database and included adult patients diagnosed with OC who initiated 1LM niraparib monotherapy after first-line platinum-based chemotherapy. Patients were followed until the earliest occurrence of last clinical activity, death, or end of study period. TTNT was measured from 1LM niraparib initiation to the start of second-line treatment or death. Cox proportional hazards models assessed univariable and multivariable associations between baseline characteristics and TTNT. RESULTS: Of 7872 patients diagnosed with OC, 526 met the eligibility criteria and were included in this analysis. Median (IQR) duration of follow-up was 14.1 (7.4-23.6) months. In univariable analyses, age, BRCA/homologous recombination deficiency (HRD) status, socioeconomic status, stage at initial diagnosis, cytoreductive surgery type, and residual disease status were significantly associated with observed TTNT and were introduced into the multivariable model with other clinically relevant variables. In the multivariable analysis, BRCA/HRD status, cytoreductive surgery type, and residual disease status were significantly associated with observed TTNT after covariate adjustment. Conversely, age, Eastern Cooperative Oncology Group performance status, disease stage, niraparib starting dose status, and first-line bevacizumab use were not associated with observed TTNT. CONCLUSION: This real-world, retrospective, observational analysis offers valuable insights on prognostic factors associated with TTNT in patients with OC treated with 1LM niraparib monotherapy after first-line platinum-based chemotherapy. Future studies are needed to examine how additional patient characteristics associated with clinical outcomes may guide treatment decisions and improve outcomes.

OBJECTIVE: Previous studies have shown that first-line (1L) maintenance therapy (MT) with poly(ADP-ribose) polymerase inhibitors and/or bevacizumab improves outcomes among patients with advanced ovarian cancer (OC); however, these treatments are underutilized. This study aimed to provide a real-world understanding of MTs among patients with advanced OC who received 1L platinum-based chemotherapy (PBC). METHODS: A retrospective chart review using iKnowMed electronic health records to identify patients aged ≥18 years with advanced OC who initiated 1L PBC between January 1, 2018-December 31, 2020. Following 1L PBC, patients could have received MT or active surveillance (AS). Kaplan-Meier methods were used to estimate time to treatment discontinuation (TTD), real-world progression-free survival (rwPFS), and overall survival (OS). RESULTS: Of the 600 chart-reviewed patients included, 239 (39.8 %) received MT and 315 (52.5 %) received AS. Patients who were

PURPOSE OF REVIEW: The aim of this review is to highlight key published oral immunotherapy (OIT) protocols and post-desensitization strategies for the major food allergens and to cover important concepts to consider when evaluating OIT for food-allergic patients. Shared decision-making should help identify patient and family values which will help influence the type of evidence-based protocol and maintenance strategy to use. RECENT FINDINGS: With food OIT emerging as a treatment option, there is a pressing need for patients, physicians, and other providers to have a nuanced understanding of the management choices available to them. There are now randomized controlled trials (RCT) of OIT for peanut, egg, milk, and wheat, and reports of cohorts of patients who have undergone OIT for tree nuts and sesame clinically. The current published protocols contain significant diversity in terms of starting dose, build-up schedule, maintenance dose, and even the product used for desensitization. Emerging data can help direct the long-term maintenance strategy for patients on OIT. Based on patient and family values elicited through the shared decision-making process, an OIT protocol may be selected that balances the level of desensitization, potential side effects, frequency of clinic visits, and potential to induce sustained unresponsiveness, among other factors. Once maintenance dosing is reached, most patients will need to maintain regular exposure to the food allergen to remain desensitized. The option to transition to commercial food products with equivalent amounts of food protein as the OIT maintenance dose would simplify the dosing process and perhaps improve palatability as well. Less frequent or decreased OIT dosing can provide practical benefits but may affect the level of desensitization and safety for some patients.

At first recurrence, platinum-sensitive ovarian cancer (PSOC) is frequently treated with platinum-based chemotherapy doublets plus bevacizumab, then single-agent bevacizumab. Most patients' disease progresses within a year after chemotherapy, emphasizing the need for novel strategies. Mirvetuximab soravtansine-gynx (MIRV), an antibody–drug conjugate, comprises a folate receptor alpha (FRα)-binding antibody and tubulin-targeting payload (maytansinoid DM4). In FRα-high PSOC, MIRV plus bevacizumab previously showed promising efficacy (objective response rate, 69% [95% CI: 41–89]; median progression-free survival, 13.3 months [95% CI: 8.3–18.3]; median duration of response, 12.9 months [95% CI: 6.5–15.7]) and safety. The Phase III randomized GLORIOSA trial will evaluate MIRV plus bevacizumab vs. bevacizumab alone as maintenance therapy in patients with FRα-high PSOC who did not have disease progression following second-line platinum-based doublet chemotherapy plus bevacizumab. Clinical Trial Registration: ClinicalTrials.gov ID: NCT05445778; GOG.org ID: GOG-3078; ENGOT.ESGO.org ID: ENGOT-ov76 Plain Language Summary Most patients with ovarian cancer are initially treated with platinum-based chemotherapy. If the cancer reappears/recurs after more than 6 months following this therapy, it is called platinum-sensitive ovarian cancer (PSOC). Patients with PSOC usually receive additional platinum-based chemotherapy along with bevacizumab, a drug that reduces tumor growth by decreasing its blood supply. If patients improve or are stable on this therapy, they are usually kept on bevacizumab alone for 'maintenance therapy'. Unfortunately, this maintenance therapy does not work long-term in all patients, so better long-term treatments are needed. The GLORIOSA (NCT05445778) clinical trial will compare maintenance therapy with bevacizumab alone to maintenance therapy with bevacizumab plus a drug called mirvetuximab soravtansine-gynx (MIRV) to determine which therapy leads to better results in patients with PSOC. MIRV is made up of an antibody that binds to a specific protein (folate receptor alpha [FRα]) on cancer cells to directly deliver a cancer-killing drug. MIRV received US FDA approval to be used as a therapy for patients with ovarian cancer who are resistant to platinum-based chemotherapy and express high levels of FRα. The GLORIOSA trial will study maintenance therapy with MIRV plus bevacizumab in patients with PSOC who have not had cancer progression after second-line platinum-based chemotherapy plus bevacizumab, and whose cancer expresses high amounts of FRα. The main purpose of this trial is to determine if MIRV plus bevacizumab leads to better patient survival and decreases cancer growth and spread when compared with bevacizumab alone. Tweetable Abstract GLORIOSA is an ongoing randomized, open-label, Phase III #clinicaltrial of mirvetuximab soravtansine + bevacizumab vs. bevacizumab alone as maintenance therapy in FRα-high platinum-sensitive ovarian, fallopian tube or primary peritoneal cancer. Article highlights Background Epithelial ovarian cancer is typically diagnosed at a late stage, and up to 80% of patients experience recurrence after initially responding to platinum-based chemotherapy. Disease that progresses >6 months after platinum-based treatment is traditionally referred to as platinum-sensitive ovarian cancer (PSOC). Patients with PSOC are frequently treated with platinum-based chemotherapy doublets plus bevacizumab followed by single-agent bevacizumab at first recurrence, and many experience disease progression within a year of chemotherapy. Folate receptor alpha (FRα) is overexpressed in 72–97% of ovarian tumors. Mirvetuximab soravtansine-gynx (MIRV) is an antibody–drug conjugate comprising an FRα-binding antibody attached via a cleavable linker to the maytansinoid DM4 payload, a potent microtubule inhibitor. Findings from the confirmatory, randomized, global, Phase III MIRASOL trial (NCT04209855) supported full approval of MIRV by the US Food and Drug Administration (March 2024) for patients with FRα-high platinum-resistant ovarian cancer (PROC) who have received one to three prior lines of therapy. The combination of MIRV and bevacizumab previously showed high clinical activity, durable responses, and a manageable safety profile in participants with PSOC and PROC across all FRα expression levels, regardless of prior bevacizumab exposure (Phase Ib/2 FORWARD II trial, NCT02606305). GLORIOSA Trial GLORIOSA, a randomized, open-label, Phase III trial (NCT05445778), will evaluate MIRV plus bevacizumab vs. bevacizumab alone as maintenance therapy in participants with FRα-high PSOC whose disease has not progressed after second-line (2L) platinum-based chemotherapy doublet plus bevacizumab. Prior to randomization, patients must have received four to eight cycles of standard 2L platinum-based chemotherapy doublet with ≥3 cycles of bevacizumab ("triplet therapy"). Patients can be screened and enrolled via two methods: before initiation (participants complete a run-in before enrollment into the randomized portion of the trial) or after completion (participants are enrolled directly into the randomized portion of the trial) of standard 2L triplet therapy. Entry into the randomized portion of the trial will be limited to patients without disease progression following their 2L triplet therapy. The primary end point is investigator-assessed progression-free survival (also assessed by blinded independent central review). The key secondary end point is overall survival. Other secondary end points include evaluation of adverse events, second progression-free survival, objective response rate, duration of response, disease-free survival, cancer antigen 125 response rate and patient-reported outcomes. Conclusion The GLORIOSA trial will define the role of MIRV plus bevacizumab as a novel maintenance regimen in patients with FRα-high PSOC whose disease has not progressed after 2L platinum-based chemotherapy doublet plus bevacizumab.

We assessed real-world trends in the use of maintenance therapy [MT] (i.e., polyADP-ribose polymerase inhibitors (PARPi) and/or bevacizumab following platinum-based chemotherapy), among U.S. patients with ovarian cancer. Using Medicare and commercial administrative health claims data from Optum's de-identified Clinformatics® Data Mart Database, we identified patients who had been diagnosed with ovarian cancer between January 1, 2010, and March 31, 2021, and received platinum-based chemotherapy and MT. Multivariable logistic regression and Cox proportional hazards regression were used to evaluate associations between demographic and clinical characteristics and MT use. Our study included 6339 patients, with a median age of 70 years. The majority were White (70.1 %), Medicare-insured (71.9 %), and were treated in the South (42.5 %). Of the 31.5 % who received MT, 18.1 % received bevacizumab alone, 10.2 % PARPi alone, and 3.3 % both. After adjusting for insurance type, PARPi and bevacizumab use increased significantly from 2017 to 2020. Patients with a high Elixhauser comorbidity index were more likely to receive MT than were patients with a low index [OR (95 % CI): 1.46 (1.28–1.67), p < 0.0001]. PARPi use was significantly associated with treatment in the South [1.42 (1.10–1.83), p = 0.01]. Compared to patients who received neither agents, those who received bevacizumab, alone or in combination with PARPi, had a higher risk of death [HR = 2.02 (95 % CI: 1.70–2.28, p < 0.0001) and 1.66 (1.24–2.23), p = 0.001, respectively]. The majority of patients with ovarian cancer are not utilizing maintenance therapy after platinum-based chemotherapy. Age, comorbidity status, and geographic region of treatment were associated with MT use. Understanding the factors and real-world outcomes associated with MT use is important to support patients in making value concordant and informed decisions. • Age, comorbidity status, and geographic region of treatment were associated with ovarian cancer maintenance therapy use. • After adjusting for insurance type, both PARPi and bevacizumab use increased significantly from 2017 to 2020. • We found relatively low use of PARPi plus bevacizumab, despite being associated with a longer progression-free survival.

Pediatric ALK-positive anaplastic large cell lymphoma is a rare subtype of non-Hodgkin lymphoma, and approximately 30% of patients relapse following treatment with conventional chemotherapy. Alectinib monotherapy has demonstrated excellent activity in relapsed and refractory ALCL, but its role as a maintenance therapy after hematopoietic cell transplantation is unclear. We experienced a relapse case of pediatric ALK-positive ALCL with central nervous system involvement treated with alectinib maintenance therapy following cord blood transplantation. The patient has maintained complete remission for more than 3 years after transplantation. There were no remarkable adverse effects that led to discontinuation of alectinib. [ABSTRACT FROM AUTHOR]

Introduction: The substantial economic burden of acute myeloid leukemia (AML) could be reduced with post-remission maintenance therapies that delay relapse. Real-world healthcare resource utilization (HCRU) data and costs among patients with AML receiving oral azacitidine (Oral-AZA) maintenance therapy or no maintenance are not well understood. We characterize HCRU and costs among these patients in clinical practice in the USA. Methods: Data from IQVIA PharMetrics® Plus (January 1, 2016–June 30, 2022) were used. Patients ≥ 18 years who were newly diagnosed with AML, received first-line systemic induction therapy, and attained disease remission were eligible. Patients receiving Oral-AZA maintenance and those receiving no maintenance ("watch and wait" [W&W]) were matched 1:3 on baseline characteristics using propensity score matching (PSM) and followed until hematopoietic stem cell transplantation or end of continuous insurance enrollment, whichever occurred first. Outcomes included treatment patterns, inpatient and outpatient visits, and costs. Results: After PSM, the Oral-AZA cohort included 43 patients and the W&W cohort 129. Of the 43 patients receiving Oral-AZA, 88.4% started at the recommended dose of 300 mg and 11.6% at 200 mg. The Oral-AZA cohort had significantly (p = 0.0025) longer median (95% CI) time to relapse from the index maintenance date (median not reached [NR; 9.0 months–NR] vs 3.3 months [0.8 months–NR]), and fewer per person per month (PPPM) hospitalizations (0.23 vs 0.61; p = 0.0005) and overall outpatient visits (5.77 vs 7.58; p = 0.0391) than the W&W cohort. Despite higher AML drug costs PPPM in the Oral-AZA cohort ($16,401 vs $10,651 for W&W), total healthcare costs PPPM were lower ($25,786 vs $38,530 for W&W; p < 0.0001). Conclusions: Patients with newly diagnosed AML treated with Oral-AZA maintenance in clinical practice had prolonged remission and lower HCRU and costs than patients receiving no maintenance therapy. These findings underscore the clinical and economic value of Oral-AZA in clinical practice. [ABSTRACT FROM AUTHOR]

Objective: Poly (ADP-ribose) polymerase (PARP) inhibitors such as olaparib and niraparib have shown promise in extending progression-free survival (PFS) in patients with platinum-sensitive recurrent (PSR) epithelial ovarian cancer. In this retrospective study, we aimed to present our own data on the effect of PARP inhibitors on PFS in recurrent epithelial ovarian cancer. Methods: 82 patients diagnosed with PSR epithelial ovarian, tubal, or primary peritoneal cancer between May 2017 and September 2023 were initially enrolled from our hospital. However, 16 patients had prior exposure to PARP inhibitors during primary treatment, and 11 were lost to follow-up. Consequently, the study focused on 55 eligible patients. PFS was compared between patients receiving PARP inhibitor maintenance therapy and those who did not. Results: Among the 55 patients with PSR epithelial ovarian cancer, 18 received olaparib as maintenance therapy, 19 received niraparib, and 18 opted for observation. PARP inhibitor therapy significantly extended PFS (mean 24.0 months) compared to observation (mean 9.0 months, p = 0.0005), regardless of BRCA mutation status (HR = 0.20, 95% CI: 0.08–0.50). Subgroup analysis showed no statistical difference between olaparib and niraparib. Additionally, there was no PFS difference based on BRCA mutation status within both PARP inhibitor groups. Conclusion: Our retrospective study demonstrates that PARP inhibitor maintenance therapy, including olaparib and niraparib, significantly prolongs PFS in patients with PSR epithelial ovarian, tubal, or primary peritoneal cancer, These findings support the broad utilization of PARP inhibitors as a standard maintenance therapy for PSR epithelial ovarian cancer irrespective of BRCA mutation status. Summary: PARP inhibitor maintenance therapy, including olaparib and niraparib, significantly prolongs PFS in patients with PSR epithelial ovarian, tubal, or primary peritoneal cancer, irrespective of BRCA mutation status. PARP inhibitors can be recommended as a standard maintenance therapy for PSR epithelial ovarian cancer. [ABSTRACT FROM AUTHOR]

Aim: To summarize and analyze the research trends and frontiers in maintenance therapy for ovarian cancer over the past 20 years. Methods: Relevant articles were identified in Web of Science, and analyzed using CiteSpace and Excel. Results: 1204 articles from 61 countries led by the USA and England were included. 6821 authors, 2345 institutions and 292 journals have participated in the publication of papers, but the collaboration between them was not very close. The annual publication volume has increased significantly since 2015. Drug combination therapy, genetic testing, management of adverse reaction and prognostic factors are research trends and frontiers of this field. Conclusion: This is the first bibliometric research in this field, which can provide some references for researchers. Article highlights This is the first bibliometric research about maintenance therapy for ovarian cancer. A total of 1204 articles were collected in this study from January 2000 to September 2022, with 728 articles and 476 reviews. Since 2015, the number of articles has rapidly increased, and will continue to grow, indicating that maintenance therapy for ovarian cancer is receiving increasing attention from scholars. The top two most cited publications focused on Niraparib and Olaparib Maintenance Therapy in Platinum-Sensitive, Recurrent Ovarian Cancer. The USA and England were the top two ranked countries with the most publications. However, less cooperation was observed among institutions from these countries. The USA and Univ Texas MD Anderson Canc Ctr were the most impact country and institution, respectively. Chemotherapy drugs alone, PARP inhibitors alone, or antiangiogenesis drugs alone were used for 1st-line, 2rd-line, or late-line maintenance therapy are the research foundation. Drug combination maintenance therapy based on effective monotherapy, as well as genetic testing, management of adverse reaction and prognostic factors are research trends and frontiers of maintenance therapy for ovarian cancer.

Introduction: Proliferative lupus nephritis is a common and severe complication of systemic lupus erythematosus. Affected patients are at an increased risk of developing chronic kidney disease, end-stage kidney disease, and extra-renal comorbidities. In recent years, the prognosis for patients with proliferative lupus nephritis has improved thanks to advancements in management regimens. Despite these advances, lupus nephritis continues to present therapeutic complexities and unmet needs. Areas covered: Research was conducted across major databases to identify the most relevant articles pertaining to immune-mediating and immunosuppressive therapies in lupus nephritis. Expert opinion: The prognosis for patients with proliferative lupus nephritis remains severe. Some drugs used in this disease may be unable to control activity, and most of them have a low therapeutic index and may cause severe and life-threatening side effects. Nonetheless, better management of traditional drugs and the introduction of novel therapies have improved renal prognosis and reduced local and systemic adverse events in patients with proliferative lupus nephritis.

• For IgG4-related disease, rituximab induction therapy has shown satisfactory efficacy and favorable safety profile. • Rituximab maintenance therapy further reduces the relapse rate and prolongs the free-relapse time of IgG4-related disease patients. • Further research, especially randomized control trials, encompassing larger sample sizes and long-term follow-up, is warranted to evaluate the efficacy and safety of rituximab induction and maintenance therapy in the treatment of IgG4-related disease. Previous studies have reported that rituximab (RTX) therapy might be beneficial in reducing relapse rates in patients with IgG4-related disease (IgG4-RD). Therefore, we aimed to systematically assess the efficacy and safety of RTX induction treatment and the effect of RTX maintenance in patients with IgG4-RD. The protocol was registered in the PROSPERO (CRD42023427352). PubMed, Embase, the Cochrane database, Scopus, and the Web of Science were interrogated to identify studies that evaluated the impact of RTX on prognosis in IgG4-RD. We explored the impact of various subgroups of factors on relapse outcomes and focused on the possible role of maintenance therapy in reducing relapse rates. The pooled incidence of adverse events of RTX therapy and the influencing factors have also been evaluated. Eighteen studies comprising 374 patients (mean age 56.0 ± 8.7 years; male 73.7 %) with a mean follow-up duration of 23.4 ± 16.3 months were included. The pooled estimate of the response rate, complete remission rate, overall relapse rate, adverse event rate, and serious adverse event rate of RTX induction therapy were 97.3 % (95 % CI, 94.7 %–99.1 %), 55.8 % (95 % CI, 39.6 %–71.3 %), 16.9 % (95 % CI, 8.7 %–27.1 %), 31.6 % (95 % CI, 16.7 %–48.9 %) and 3.9 % (95 % CI, 0.8 %–8.9 %), respectively. In subgroup analysis, the pooled relapse rate was significantly lower in studies with maintenance than without maintenance (2.8% vs 21.5 %, p < 0.01). Pooled Kaplan-Meier relapse curves also demonstrated that RTX maintenance therapy provided a better prognosis. RTX induction therapy appears to have satisfactory efficacy in the induction of remission in IgG4-RD. In addition, prophylactic RTX maintenance therapy after induction may be beneficial in preventing relapse of IgG4-RD. [ABSTRACT FROM AUTHOR]

Purpose: To examine patterns of short-acting ß2-agonist (SABA) and maintenance therapy claims surrounding the subset of severe asthma exacerbations associated with outpatient, urgent care, or emergency department visits or hospitalization (termed serious exacerbations) in patients treated as intermittent or mild persistent asthma. Methods: This was a retrospective study of 2010– 2017 administrative claims from MerativeTM MarketScan® US databases for patients ≥ 12 years filling a SABA prescription for asthma (index). Patients had ≥ 12 months continuous insurance eligibility pre- and post-index and ≥ 1 additional SABA and/or maintenance medication fill appropriate for mild persistent asthma post-index. Prescription fills were assessed over 30 days before and after a serious exacerbation event. Results: Of 323,443 patients (mean [standard deviation] age: 34.9 [18.2] years; 62.0% female) treated as intermittent or mild persistent asthma, 51,690 (16.0%) experienced ≥ 1 serious exacerbation post-index. During the 30 days pre-event, a greater proportion of patients filled a SABA versus maintenance therapy (24.6% vs 19.0%; odds ratio [OR]: 1.39, 95% confidence interval [CI]: 1.35– 1.43; p < 0.001); during the 30 days post-event, patients were more likely to fill maintenance medication versus SABA (88.6% vs 67.0%; OR [95% CI]: 3.88 [3.75– 4.01]; p < 0.001). The closer in time prior to the event, the greater the likelihood of filling a SABA versus maintenance prescription (OR [95% CI]; 1– 7 days pre-event: 1.42 [1.36– 1.48]; 8– 14 days pre-event: 1.34 [1.27– 1.41]; 15– 30 days pre-event: 1.18 [1.12– 1.24]; all p < 0.001). Over 4.5 times more patients filled a maintenance therapy within 7 days post-event (45,014) versus all 30 days pre-event (9835) (OR [95% CI]: 28.7 [27.7– 29.7]; p < 0.001). Conclusion: These patterns of SABA rescue and maintenance fills suggest that a "window of opportunity" may exist to interrupt a serious exacerbation occurrence for patients treated as intermittent or mild persistent asthma if symptoms and inflammation are addressed concomitantly.

Abstract Objective Poly (ADP-ribose) polymerase (PARP) inhibitors such as olaparib and niraparib have shown promise in extending progression-free survival (PFS) in patients with platinum-sensitive recurrent (PSR) epithelial ovarian cancer. In this retrospective study, we aimed to present our own data on the effect of PARP inhibitors on PFS in recurrent epithelial ovarian cancer. Methods 82 patients diagnosed with PSR epithelial ovarian, tubal, or primary peritoneal cancer between May 2017 and September 2023 were initially enrolled from our hospital. However, 16 patients had prior exposure to PARP inhibitors during primary treatment, and 11 were lost to follow-up. Consequently, the study focused on 55 eligible patients. PFS was compared between patients receiving PARP inhibitor maintenance therapy and those who did not. Results Among the 55 patients with PSR epithelial ovarian cancer, 18 received olaparib as maintenance therapy, 19 received niraparib, and 18 opted for observation. PARP inhibitor therapy significantly extended PFS (mean 24.0 months) compared to observation (mean 9.0 months, p = 0.0005), regardless of BRCA mutation status (HR = 0.20, 95% CI: 0.08–0.50). Subgroup analysis showed no statistical difference between olaparib and niraparib. Additionally, there was no PFS difference based on BRCA mutation status within both PARP inhibitor groups. Conclusion Our retrospective study demonstrates that PARP inhibitor maintenance therapy, including olaparib and niraparib, significantly prolongs PFS in patients with PSR epithelial ovarian, tubal, or primary peritoneal cancer, These findings support the broad utilization of PARP inhibitors as a standard maintenance therapy for PSR epithelial ovarian cancer irrespective of BRCA mutation status.

Abstract Introduction Niraparib first-line maintenance (1LM) therapy has demonstrated clinical benefit for patients with ovarian cancer (OC) in clinical trial and real-world settings, but data on factors associated with real-world patient outcomes remain limited. This analysis identified patient characteristics associated with time to next treatment (TTNT), a proxy for real-world progression-free survival, in patients with OC treated with 1LM niraparib monotherapy. Methods This retrospective observational study used a USA nationwide electronic health record-derived deidentified database and included adult patients diagnosed with OC who initiated 1LM niraparib monotherapy after first-line platinum-based chemotherapy. Patients were followed until the earliest occurrence of last clinical activity, death, or end of study period. TTNT was measured from 1LM niraparib initiation to the start of second-line treatment or death. Cox proportional hazards models assessed univariable and multivariable associations between baseline characteristics and TTNT. Results Of 7872 patients diagnosed with OC, 526 met the eligibility criteria and were included in this analysis. Median (IQR) duration of follow-up was 14.1 (7.4–23.6) months. In univariable analyses, age, BRCA/homologous recombination deficiency (HRD) status, socioeconomic status, stage at initial diagnosis, cytoreductive surgery type, and residual disease status were significantly associated with observed TTNT and were introduced into the multivariable model with other clinically relevant variables. In the multivariable analysis, BRCA/HRD status, cytoreductive surgery type, and residual disease status were significantly associated with observed TTNT after covariate adjustment. Conversely, age, Eastern Cooperative Oncology Group performance status, disease stage, niraparib starting dose status, and first-line bevacizumab use were not associated with observed TTNT. Conclusion This real-world, retrospective, observational analysis offers valuable insights on prognostic factors associated with TTNT in patients with OC treated with 1LM niraparib monotherapy after first-line platinum-based chemotherapy. Future studies are needed to examine how additional patient characteristics associated with clinical outcomes may guide treatment decisions and improve outcomes.

Abstract Background Prompt and effective management with maintenance therapy (single or dual bronchodilator therapy) is recommended after the initial diagnosis of chronic obstructive pulmonary disease (COPD) to maintain lung function and prevent exacerbations. Contrary to guideline-based recommendations, most patients are not prescribed maintenance treatment at initial diagnosis. The current study assessed the pharmacologic treatment patterns and outcomes of newly diagnosed patients with COPD in the USA. Methods This retrospective, noninterventional study used de-identified data from the Inovalon Insights’ database (Commercial, Medicaid Managed Care, and Medicare Advantage–insured individuals) between January 1, 2015, and December 31, 2021. The “patient journey” from initial diagnosis was followed over a 4-year period. The primary outcome measure was the number of moderate or severe exacerbations. Secondary outcome measures included the cumulative incidence of exacerbations, mean cumulative count of moderate and severe exacerbations, rates of moderate and severe exacerbations in patients who remained untreated after diagnosis in 12-month time periods for 4 years, sociodemographic and clinical characteristics, and pharmacologic treatment patterns. Results The cohort consisted of 238,158 newly diagnosed patients with COPD (female [52.9%]; mean age 63.8 years). The majority of patients with COPD had Medicaid as their primary insurance (46.2%). Overall, during the 4-year follow-up period, 32.9% of the patients had at least one moderate or severe exacerbation, and 25.8% and 13.8% experienced moderate and severe exacerbations, respectively. At diagnosis, 86.2% of the patients were untreated and most remained untreated by the end of the follow-up (63.8%). Most patients (62.0%) received long-acting beta-agonist (LABA)/inhaled corticosteroids (ICS) as their initial treatment at diagnosis, and LABA/ICS continued to be the most common initial treatment during the 4-year period (64.0% at year 1; 58.0% at year 4). Conclusions Most patients with COPD were not treated at initial diagnosis and remained untreated during follow-up. Our data highlight a lack of adherence to recommendations for clinical practice.

This study aimed to understand how physicians make COPD treatment decisions, and how combination maintenance therapies are utilized in a real-world setting.Patients and Methods: This exploratory, hypothesis-generating, non-interventional study used a cross-sectional online survey that was administered to a sample of practicing physicians in the United States. The survey included five fictitious vignettes detailing common symptoms experienced by patients with COPD. Survey questions included factors physicians consider in their decisions, and perceived barriers to prescribing treatments. Repeated measures multivariable analyses were conducted to evaluate how likely physicians were to switch to triple therapy versus no change to patient’s current maintenance therapy or change to another maintenance therapy.Results: In total, 200 physicians completed the survey. Cost of treatment and patient access to treatment were reported as the most common barriers physicians consider in their prescribing decisions. Physicians were more likely to switch a patient’s maintenance inhaler to triple therapy versus no change to maintenance inhaler if they considered the patient’s history of new symptoms, insurance status, and clinical guidelines in their decision. Physicians with more experience treating patients with COPD, and those who treat more patients with COPD per week, were more likely to switch to triple therapy versus no change to maintenance inhaler.Conclusion: This study demonstrates the complexity of factors that can influence physicians’ decisions when prescribing treatments for patients with COPD, including considerations of treatment cost, patient access and adherence, patient comorbidities, efficacy of current treatment, clinical guidelines, and provider’s level of experience treating COPD. Further research may help elucidate the relative importance of the factors influencing physicians’ decisions and inform what types of decision-support tools would be most beneficial.Plain Language Summary: Chronic obstructive pulmonary disease (COPD) symptoms can be effectively managed with maintenance therapies, which are treatments that are taken routinely to help improve symptoms. A combination of three different therapies (triple therapy maintenance) has been shown to be more effective than a combination of two different therapies (dual therapy maintenance) in patients with moderate-to-severe COPD. However, maintenance therapies, including triple therapy, are underutilized. This study aimed to explore how physicians make their treatment decisions for patients with COPD, and how combination maintenance therapies are utilized. To do so, we administered a survey to a sample of practicing physicians in the United States. The survey included five clinically based, fictitious profiles, or vignettes, of patients with COPD, with common symptoms and patient characteristics being described. Physicians were then asked to answer questions about what treatment they would prescribe for each patient, and any factors they considered when deciding on a treatment for a patient. We found that cost of treatment and patient access to treatment were the most common barriers that physicians considered when choosing a treatment. Physicians were also more likely to switch a patient’s maintenance inhaler to a triple therapy maintenance inhaler if they considered the patient’s history of new symptoms, patient’s insurance status, and clinical guidelines when making their decisions. Our study shows that there are many complex factors that influence physicians’ decisions when deciding on a treatment for patients with COPD.Keywords: maintenance therapy, patient vignette, pharmacotherapy, physician survey, real world, triple therapy

AbstractAdvanced non-small cell lung cancer (NSCLC) remains a significant clinical challenge, particularly in patients who exhibit stable disease (SD) following first-line chemotherapy combined with immunotherapy. This study aims to evaluate the efficacy and safety of Anlotinib, a novel multitarget tyrosine kinase inhibitor, as maintenance therapy in this patient cohort. This retrospective, single-center study enrolled patients with advanced NSCLC who showed SD after receiving a combination of first-line chemo-immunotherapy for 4 cycles, then add anlotinib to subsequent standard maintenance therapy, continuing treatment until disease progression or the occurrence of intolerable toxic side effects. The primary endpoint was progression-free survival (P FS), overall survival (OS), objective response rate (ORR), disease control rate (DCR) and safety profile. A total of 52 patients were enrolled, the median P FS and OS was 5.0m and 10.0m, respectively. The ORR and DCR was 28.85% and 67.31%. subgroup analysis indicated that its efficacy correlate with certain Adverse Effects (AEs, such as hypertension, proteinuria, and hand-foot syndrome). Further mechanistic analysis suggests that this regimen may likely reduce immune suppression by depleting Tregs, thereby further activating the immune system to exert synergistic anti-tumor effects. Besides promising efficacy, the toxicity can be tolerated. Anlotinib demonstrates promising efficacy as a maintenance therapy in patients with advanced NSCLC who have achieved SD following first-line chemotherapy combined with immunotherapy. The manageable safety profile and the observed extension in P FS and OS suggest that Anlotinib could be a valuable therapeutic option for this challenging patient population. Further large-scale randomized controlled trials are warranted to confirm these findings and to optimize patient selection and management strategies. [ABSTRACT FROM AUTHOR]

Background: Prompt and effective management with maintenance therapy (single or dual bronchodilator therapy) is recommended after the initial diagnosis of chronic obstructive pulmonary disease (COPD) to maintain lung function and prevent exacerbations. Contrary to guideline-based recommendations, most patients are not prescribed maintenance treatment at initial diagnosis. The current study assessed the pharmacologic treatment patterns and outcomes of newly diagnosed patients with COPD in the USA. Methods: This retrospective, noninterventional study used de-identified data from the Inovalon Insights' database (Commercial, Medicaid Managed Care, and Medicare Advantage–insured individuals) between January 1, 2015, and December 31, 2021. The "patient journey" from initial diagnosis was followed over a 4-year period. The primary outcome measure was the number of moderate or severe exacerbations. Secondary outcome measures included the cumulative incidence of exacerbations, mean cumulative count of moderate and severe exacerbations, rates of moderate and severe exacerbations in patients who remained untreated after diagnosis in 12-month time periods for 4 years, sociodemographic and clinical characteristics, and pharmacologic treatment patterns. Results: The cohort consisted of 238,158 newly diagnosed patients with COPD (female [52.9%]; mean age 63.8 years). The majority of patients with COPD had Medicaid as their primary insurance (46.2%). Overall, during the 4-year follow-up period, 32.9% of the patients had at least one moderate or severe exacerbation, and 25.8% and 13.8% experienced moderate and severe exacerbations, respectively. At diagnosis, 86.2% of the patients were untreated and most remained untreated by the end of the follow-up (63.8%). Most patients (62.0%) received long-acting beta-agonist (LABA)/inhaled corticosteroids (ICS) as their initial treatment at diagnosis, and LABA/ICS continued to be the most common initial treatment during the 4-year period (64.0% at year 1; 58.0% at year 4). Conclusions: Most patients with COPD were not treated at initial diagnosis and remained untreated during follow-up. Our data highlight a lack of adherence to recommendations for clinical practice.

Introduction: Chimeric antigen receptor (CAR)-T cells obtained long-term durability in about 30% to 40% of relapsed/refractory (r/r) B-cell non-Hodgkin lymphoma (B-NHL). Maintenance therapy after CAR-T is necessary, and PD1 inhibitor is one of the important maintenance therapy options. Methods: A total of 173 r/r B-NHL patients treated with PD1 inhibitor maintenance following CD19/22 CAR-T therapy alone or combined with autologous hematopoietic stem cell transplantation (ASCT) from March 2019 to July 2022 were assessed for eligibility for two trials. There were 81 patients on PD1 inhibitor maintenance therapy. Results: In the CD19/22 CAR-T therapy trial, the PD1 inhibitor maintenance group indicated superior objective response rate (ORR) (82.9% vs 60%; P = 0.04) and 2-year progression-free survival (PFS) (59.8% vs 21.3%; P = 0.001) than the non-maintenance group. The estimated 2-year overall survival (OS) was comparable in the two groups (60.1% vs 45.1%; P = 0.112). No difference was observed in the peak expansion levels of CD19 CAR-T and CD22 CAR-T between the two groups. The persistence time of CD19 and CD22 CAR-T in the PD1 inhibitor maintenance group was longer than that in the non-maintenance group. In the CD19/22 CAR-T therapy combined with ASCT trial, no significant differences in ORR (81.4% vs 84.8%; P = 0.67), 2-year PFS (72.3% vs 74.9%; P = 0.73), and 2-year OS (84.1% vs 80.7%; P = 0.79) were observed between non-maintenance and PD1 inhibitor maintenance therapy groups. The peak expansion levels and duration of CD19 and CD22 CAR-T were not statistically different between the two groups. During maintenance treatment with PD1 inhibitor, all adverse events were manageable. In the multivariable analyses, type and R3m were independent predictive factors influencing the OS of r/r B-NHL with PD1 inhibitor maintenance after CAR-T therapy. Conclusion: PD1 inhibitor maintenance following CD19/22 CAR-T therapy obtained superior response and survival in r/r B-NHL, but not in the trial of CD19/22 CAR-T cell therapy combined with ASCT.

Multiple myeloma (MM) stands as the second most prevalent hematological malignancy, constituting approximately 10% of all hematological malignancies. Current guidelines recommend upfront autologous stem cell transplantation (ASCT) for transplant-eligible MM patients. This study seeks to delineate factors influencing post–ASCT outcomes in MM patients. Our cohort comprised 150 MM patients from Taipei Veterans General Hospital, with progression-free survival (PFS) as the primary endpoint and overall survival (OS) as the secondary endpoint. A Cox proportional hazards model was employed to discern potential predictive factors for survival. ASCT age ≥ 65 (hazard ratio [HR] 1.94, 95% confidence interval [CI] 1.08–3.47) and the presence of extramedullary disease (HR 2.53, 95% CI 1.53–4.19) negatively impacted PFS. Conversely, treatment response ≥ VGPR before ASCT (HR 0.52, 95% CI 0.31–0.87) and total CD34+ cells collected ≥ 4 × 106 cells/kg on the first stem cell harvesting (HR 0.52, 95% CI 0.32–0.87) were positively associated with PFS. For OS, patients with ISS stage III (HR 2.06, 95% CI 1.05–4.04), the presence of extramedullary disease (HR 3.92, 95% CI 2.03–7.58), light chain ratio ≥ 100 before ASCT (HR 7.08, 95% CI 1.45–34.59), post–ASCT cytomegalovirus infection (HR 9.43, 95% CI 3.09–28.84), and a lower conditioning melphalan dose (< 140 mg/m2; HR 2.75, 95% CI 1.23–6.17) experienced shorter OS. In contrast, post–ASCT day + 15 absolute monocyte counts (D15 AMC) > 500/µl (HR 0.36, 95% CI 0.17–0.79) and post–ASCT day + 15 platelet counts (D15 PLT) > 80,000/µl (HR 0.48, 95% CI 0.24–0.94) were correlated with improved OS. Significantly, early PLT and AMC recovery on day + 15 predicting longer OS represents a novel finding not previously reported. Other factors also align with previous studies. Our study provides real-world insights for post–ASCT outcome prediction beyond clinical trials. [ABSTRACT FROM AUTHOR]

Pancreatic acinar cell carcinoma (PACC) is a rare cancer with no specific treatment. The treatment and chemotherapy for PACC are selected according to pancreatic ductal adenocarcinoma (PDAC). Herein, we describe a recurrent PACC case of an older adult patient. The patient was treated with systemic chemotherapy, chemoradiotherapy, and maintenance therapy based on the pathologic germline BRCA2 variant, resulting in long-term survival. The pathogenic BRCA variant is detected more frequently in patients with PACC than in those with PDAC. The BRCA variant significantly impacts treatment selection and prognosis; therefore, early genomic analysis is recommended when treating PACC. [ABSTRACT FROM AUTHOR]

AbstractThere are no established maintenance protocols for cutaneous lymphomas. We aim to determine patient treatments and outcomes during the COVID-19 pandemic in order to uncover the most effective maintenance protocols for cutaneous lymphomas and impact of treatment interruption. Data was collected retrospectively from nine international institutions, including 149 patients. Younger patients had earlier stages of disease and were most frequently treated with skin-directed therapies including topical steroids, mechlorethamine gel, and phototherapy. Treatment interruption varied by treatment type and stage, with patients on topical therapies and earlier stages of disease being least likely to experience interruption. Treatment interruption was significantly associated with progression of disease and worse outcomes, with twice as many patients progressing who had interruption compared to those without interruption. This study may demonstrate the significance of continuous maintenance therapies, even in younger patients with early stages of disease. [ABSTRACT FROM AUTHOR]

Objective To compare the frequency of nail changes in Chronic Kidney Disease patients undergoing haemodialysis with patients on maintenance therapy. Methods This analytical cross-sectional study was carried out at Dermatology and Nephrology Department, Sahiwal Teaching Hospitals, Sahiwal, after approval from Institutional Ethical Review Committee. A total of 158 patients with chronic kidney disease of either sex and age were divided into two groups: Group A (patients under regular haemodialysis) Group B (patients on oral therapy). Patient's demographic, clinical and laboratory data were recorded in predesigned proforma. Data were analyzed by using SPSS version 28. Results Out of total 158 patients, male female ratio was 1.1:1 and majority of patients (63.3%) were above age of 40 years. Most commonly reported nail changes in both groups were absence of lunula (65%, 57%), longitudinal ridging (54%, 58%) and onycholysis (45%, 35%) but variations were observed in their frequencies. There was no statistically significant difference in nail changes of both groups. Conclusion Patients with CKD undergoing HD therapy have slight higher frequency of nail changes compared to patients on maintenance therapy. Further studies with large sample size may elaborate Results. [ABSTRACT FROM AUTHOR]

Aim: In this study, we aimed to investigate patient characteristics, efficacy, prognostic factors, and safety of olaparib maintenance therapy for platinum‐sensitive recurrent ovarian cancer at our institution. Methods: Patients responding to platinum‐based therapy and starting olaparib maintenance therapy for recurrent epithelial ovarian, fallopian tube, or peritoneal cancer at Kurume University Hospital between January 2018 and November 2021 were enrolled in the study. Their data were extracted retrospectively from medical records. Results: In all, 50 patients were included. The median (range) age of the patients, follow‐up time, and duration of olaparib maintenance therapy were 62 (39–87) years, 21.6 (2.2–45.9) months, and 7.2 (2–45.9) months, respectively. Among the 29 patients tested for homologous recombination (HR) status, 22 (75.9%) were positive for HR deficiency (HRD), 12 (54.5%) of whom had BRCA‐positive tumors. The median progression‐free survival was 8.9 months (95% confidence interval: 6.2–12.6), and the median overall survival was 27.1 months (95% confidence interval: 22.5–40.3). Multivariate analysis of prognostic factors revealed that HRD was an independent prognostic factor for both progression‐free survival and overall survival. The most common adverse event was nausea (any grade, n = 30, 60%), resulting in drug interruption (n = 23, 46%), dose reduction (n = 17, 34%), and discontinuation of treatment (n = 1, 2%). Conclusion: Olaparib maintenance therapy for recurrent platinum‐sensitive ovarian cancer at our institution was effective, with acceptable adverse events. HRD was the most significant prognostic factor for patients with recurrent platinum‐sensitive ovarian cancer. [ABSTRACT FROM AUTHOR]

Background: Ovarian cancer (OC) is a significant cause of cancer-related mortality in women globally, with a five-year survival rate of approximately 49%. Standard therapy involves cytoreductive surgery followed by chemotherapy. Its poor prognosis has driven interest in alternative therapies such as targeted molecular agents like bevacizumab and poly (ADP-ribose) polymerase inhibitors (PARPi). Materials and Methods: This review systematically searched PubMed from January 2018 to December 2023 for studies on PARPi in OC. Emphasis was on identifying relevant Phase III trials, extracting data on study design, patient demographics, and outcomes. Special focus was on assessing PARPi efficacy, safety, impact on quality of life, and ongoing trials, including those on Clinicaltrials.gov. Results: The efficacy of PARPi in first-line therapy for OC has been extensively studied. Trials like SOLO-1, PRIMA, and ATHENA-MONO have demonstrated significant improvements in progression-free survival (PFS) and overall survival (OS), particularly in patients with BRCA mutations. Additionally, the combination of PARPi with other agents like bevacizumab has shown promising results in extending PFS. However, PARPi treatment is associated with various adverse effects, including hematologic toxicities like anemia, thrombocytopenia, and neutropenia. While most adverse events are manageable, some patients may require dose adjustments or discontinuation of treatment. Importantly, PARPi maintenance therapy has not adversely affected health-related quality of life (HRQoL), with studies reporting similar HRQoL scores between PARPi-treated and placebo-treated patients. Conclusions: PARPi offer effective treatment with manageable side effects, suitable even for medically fragile patients. Individualized dosing can optimize benefits while minimizing adverse events. Exploring diverse treatment approaches, particularly in patients with limited life expectancy or high disease burden, could improve outcomes. Ongoing research is investigating alternative therapies and combinations to broaden treatment options. Combining bevacizumab with PARPi may be justified for first-line and recurrent maintenance therapy. Regardless of mutational status, PARPi should be considered for maintenance therapy in newly diagnosed advanced OC. Platinum sensitivity remains crucial for treatment decisions and predicting survival outcomes. [ABSTRACT FROM AUTHOR]

Simple Summary: The leading cause of failure of allogeneic hematopoietic cell transplantation (allo-HCT) in patients with acute myeloid leukemia (AML) is post-transplant relapse. We urgently need strategies to decrease this risk. In the past few years, the basic framework of post-transplant maintenance has been shaped by several clinical trials investigating targeted, immunomodulatory, and cellular therapies. Although the practice of post-transplant maintenance in AML has become more common, there remain challenges regarding the feasibility and efficacy of this strategy. In this review, we discuss recent advances in post-transplant maintenance in AML, along with ongoing and future planned studies in this area, outlining the limitations of available data and our future goals. Allogeneic hematopoietic cell transplantation (allo-HCT) is potentially curative for patients with acute myeloid leukemia (AML). However, the post-transplant relapse rate ranges from 40 to 70%, particularly with reduced intensity conditioning, and remains a major cause of treatment failure for these patients due to the limited efficacy of salvage therapy options. Strategies to mitigate this risk are urgently needed. In the past few years, the basic framework of post-transplant maintenance has been shaped by several clinical trials investigating targeted therapy, chemotherapy, and immunomodulatory therapies. Although the practice of post-transplant maintenance in AML has become more common, there remain challenges regarding the feasibility and efficacy of this strategy. Here, we review major developments in post-transplant maintenance in AML, along with ongoing and future planned studies in this area, outlining the limitations of available data and our future goals.

IntroductionWe evaluated real-world outcomes in patients with advanced ovarian cancer (AOC) based on their cumulative risk profile and maintenance therapy (MT) status following first-line (1L) treatment.MethodsThis retrospective observational study of a nationwide electronic health record-derived de-identified database included adult patients diagnosed with stage III/IV OC from January 1, 2011 to February 28, 2021, who received 1L therapy and had ≥ 12 weeks of follow-up after the index date (end of 1L therapy). Patients were grouped according to whether they received MT or active surveillance (AS) following 1L treatment and by the cumulative number of risk factors (RF) present (stage IV disease; no surgery/treated with neoadjuvant therapy and interval debulking surgery; had postoperative visible residual disease; and had BRCA wild-type disease/unknown BRCA status). Time to next treatment (TTNT) and overall survival (OS) were assessed with a cloning and inverse probability of censoring (IPC)-weighted Kaplan-Meier method.ResultsAmong 1920 patients, 22.2% received MT and 77.8% received AS. Median IPC-weighted TTNT and OS were 13.3 months (95% CI 11.7-15.8) and 39.1 months (95% CI 32.5-48.6) in the MT cohort, respectively, and 8.6 months (95% CI 8.0-9.5) and 38.4 months (95% CI 36.4-41.0) in the AS cohort, respectively. Almost all patients had ≥ 1 RF (MT 95.3%; AS 96.7%). Median IPC-weighted TTNT was shorter among patients with more RF in both cohorts (MT: 1 RF, 19.3 months, 95% CI 13.5-37.8; 2 RF, 17.2 months, 95% CI 12.8-20.2; 3 RF, 11.0 months, 95% CI 8.2-13.8; 4 RF, 7.0 months, 95% CI 6.2-8.8; AS: 1 RF, 17.7 months, 95% CI 13.5-22.3; 2 RF, 10.2 months, 95% CI 9.1-11.5; 3 RF, 6.5 months, 95% CI 5.8-7.4; 4 RF, 4.1 months, 95% CI 3.5-4.5).ConclusionRegardless of RF number, MT was associated with longer TTNT in real-world patients with AOC.

The study aimed to explore the role of maintenance therapy following Cetuximab + chemotherapy and the optimal Cetuximab-based maintenance therapy regimen.Patients and Methods: We retrospectively reviewed data on the efficacy and safety of CET-based MT in patients with mCRC who achieved disease control after induction therapy.Results: Eighty-one patients with mCRC who achieved disease control after CET + chemotherapy induction were enrolled. Overall median progression-free survival (PFS) was 10.5 (95% CI = 8.8– 12.2) months and median maintenance/observation PFS (mnPFS) was 6.0 (95% CI = 5.0– 7.0) months. Among these 81 patients, 61 patients were prescribed MT (CET alone for 21 patients and CET + chemotherapy for 40 patients). Median PFS and mnPFS in the MT group were significantly longer than those for the non-MT group. Different MT regimens did not affect PFS and mnPFS significantly. Univariate and multivariate analysis demonstrated MT, complete response/partial response during induction therapy, and absence of peritoneal metastasis to be positively associated with longer PFS and mnPFS. Treatment-related adverse events (AEs) were tolerable during MT, and AE-related deaths were not observed.Conclusion: MT with CET or CET + chemotherapy was an appropriate option following initial induction chemotherapy for patients with RAS and RAF wild-type mCRC. This strategy endowed survival benefits and a tolerable safety profile.Keywords: colorectal cancer, maintenance therapy, cetuximab, RAS and RAF wild-type, targeted therapy

Abstract Background The efficacy of subsequent therapy after poly-ADP-ribose polymerase (PARP) inhibitor maintenance treatment has raised concerns. Retrospective studies show worse outcomes for platinum-based chemotherapy after progression of PARP inhibitor-maintenance therapy, especially in BRCA-mutant patients. We aimed to describe subsequent therapy in ovarian cancer patients after PARP inhibitor-maintenance therapy and evaluate their response to treatment. We focused on chemotherapy for patients with a progression-free interval (PFI) of ≥ 6 months after prior platinum treatment, based on BRCA status. Methods We analyzed real-world data from Peking University Cancer Hospital, subsequent therapy after progression to PARP inhibitor-maintenance therapy for epithelial ovarian cancer between January 2016 and December 2022. Clinicopathological characteristics and treatment outcomes were extracted from medical records. The last follow-up was in May 2023. Results A total of 102 patients were included, of which 29 (28.4%) had a germline BRCA1/2 mutation and 73 (71.6%) exhibited BRCA1/2 wild-type mutations. The PARP inhibitors used were Olaparib (n = 62, 60.8%), Niraparib (n = 35, 34.3%), and others (n = 5, 4.9%). The overall response rate (ORR) was 41.2%, and the median time to second progression (mTTSP) was 8.1 months (95%CI 5.8–10.2). Of 91 platinum-sensitive patients (PFI ≥ 6 months) after progression to PARP inhibitor-maintenance therapy, 65 patients subsequently received platinum regimens. Among them, 30 had received one line of chemotherapy before PARP inhibitor-maintenance therapy. Analysis of these 30 patients by BRCA status showed an ORR of 16.7% versus 33.3% and mTTSP of 7.1 (95% CI 4.9–9.1) versus 6.2 months (95% CI 3.7–8.3, P = 0.550), for BRCA-mutant and wild-type patients, respectively. For the remaining 35 patients who had received two or more lines of chemotherapy before PARP inhibitor-maintenance therapy, ORR was 57.1% versus 42.9%, and mTTSP was 18.0 (95% CI 5.0–31.0) versus 8.0 months (95% CI 4.9–11.1, P = 0.199), for BRCA-mutant and wild-type patients, respectively. Conclusion No differences in survival outcomes were observed among patients with different BRCA statuses. Furthermore, for patients who had undergone two or more lines of chemotherapy before PARP inhibitor maintenance therapy, no negative effects of PARP inhibitors on subsequent treatment were found, regardless of BRCA status.

Background: Antimicrobial Photodynamic therapy for the treatment of periodontitis is being increasingly gaining attention but at present, very limited data are available on the clinical and microbiological outcomes obtained following Indocyanine Green as the photosensitizer in Maintenance patients. The objective was to evaluate the efficiency of Indocyanine(ICG)-green based photodynamic therapy as an adjunct to scaling and root planing in patients enrolled in maintenance therapy. Methodology: Using a split mouth study design, 24 participants enrolled in the maintenance therapy, having diagnosed as Periodontitis, were randomly subjected to scaling and root planing(SRP). The test group additionally received ICG-based (Aurogreen ®, Aurolabs, Madurai, India,1mg/ml) aPDT with an 810nm diode laser. Clinical assessment of Plaque index, modified Sulcus bleeding index, Probing pocket depth, Clinical loss of attachment and microbiological analysis of A. actinomycetemcomitans, P. gingivalis, T. forsythia and F.nucleatum were performed at baseline and 3 months after treatment. Results: It was observed that although there was no significant difference between the test and control group at baseline and 3 months, there was a statistically significant reduction in the mean values in both the groups at 3 months. Microbiological analysis showed substantial reduction in detection frequency of the bacteria assessed at 3 months in both the groups. Conclusion: Within the limits of the study, ICG-based aPDT did not show additional advantage over SRP alone at 3 months, though it could be a promising treatment modality in maintenance patients in terms of patient comfort and the treatment time taken. More randomised clinical trials should be employed to understand the exact mode of action of ICG based aPDT and its role in treatment of periodontal disease.

Background Evidence on maintenance therapy following frontline induction is sparse in primary light-chain amyloidosis (AL), especially for those who do not undergo autologous haematopoietic stem cell transplantation (ASCT).Methods We enrolled primary AL patients who achieved at least haematologic very good partial response (VGPR) by the 4th month at the frontline from December 2008 to June 2023 at Zhongshan Hospital, Fudan University. Those who followed maintenance therapy were identified as the maintenance group (n = 44), whereas those entering the observational phase were classified as the observational group (n = 24).Results After 7.2(interquartile range, 4.7–18.6) months of maintenance therapy, 9(20.5%), 14(31.8%) and 5 (11.4%) patients achieved improvement in haematologic, cardiac and renal response respectively. Five (11.4%) patients had minimal residual disease (MRD) response conversion from positive to negative based on maintenance therapy. In the observation group, none of the patients had haematologic response improvement, with 3(12.5%) and 1(4.2%) patient showing cardiac and renal response improvement during follow-up.Conclusion This study identified the clinical benefits of maintenance therapy in patients with AL who did not undergo ASCT in real-world practice.

ABSTRACTObjectives T-cell acute lymphoblastic leukemia/lymphoblastic lymphoma (T-ALL/LBL) are highly malignant and aggressive hematologic tumors for which there is no standard first-line treatment. Chidamide, a novel histone deacetylase inhibitor, shows great promise. We assessed the efficacy and safety of an irradiation-containing conditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) and post-transplantation chidamide maintenance in patients with T-ALL/LBL.Methods We retrospectively analyzed the clinical data of six patients with T-ALL/LBL who underwent allo-HSCT with a radiotherapy-containing pretreatment regimen and post-transplant chidamide maintenance therapy. The endpoints were relapse, graft-versus-host disease (GVHD), transplant-related mortality (TRM), progression-free survival (PFS), overall survival (OS), and adverse events (AEs).Results All of the patients had uneventful post-transplant hematopoietic reconstitution, and all achieved complete molecular remission within 30 days. All six patients survived, and two relapsed with a median relapse time of 828.5 (170–1335) days. The 1-year OS rate was 100%, the 2-year PFS rate was 66.7%, and the TRM rate was 0%. After transplantation, two patients developed grade I-II acute GVHD (2/6); grade III-IV acute and chronic GVHD were not observed. The most common AEs following chidamide administration were hematological AEs, which occurred to varying degrees in all patients; liver function abnormalities occurred in two patients (grade 2), and symptoms of malaise occurred in one patient (grade 1).Conclusion Chidamide maintenance therapy after T-ALL/LBL transplantation is safe, but the efficacy needs to be further investigated.

ABSTRACTObjectives The seroprevalence of antibodies against Cytomegalovirus (CMV) is an established poor prognostic factor for patients receiving an allogeneic stem cell transplantation. However, the impact of CMV serology on outcome after autologous stem cell transplantation remains unknown.Methods Here, we analyzed the CMV immunoglobulin (Ig) serology of 446 newly-diagnosed multiple myeloma (MM) patients of the GMMG-MM5 phase III trial with a median follow-up of 58 months.Results CMV IgG and IgM positivity was seen in 51% and 6% of the patients, respectively. In multivariate analysis CMV IgG and CMV IgM serology show an age-depending effect for PFS. We identified positive CMV IgG/positive CMV IgM serology as an age-depending beneficial factor on PFS.Discussion Younger patients with a positive CMV IgG/positive CMV IgM serology experienced a favorable effect on PFS, whereas a positive CMV IgG/positive CMV IgM serology at older age has a disadvantageous effect on PFS.

Introduction In advanced basal cell carcinoma (BCC), the issue of whether Hedgehog inhibitors (HHIs) should be stopped or not after clinical complete response (cCR) achievement remains an unmet clinical need. Materials and Methods We conducted a retrospective, multicenter study across 7 Italian dermato-oncology units including patients with BCC who continued vismodegib after cCR between 2012 and 2019. We assessed the relationship between the duration of vismodegib intake (days to cCR [DTCR], days to stop after cCR [DTS], total treatment days [TTD]), and disease-free survival (DFS). Reasons to stop vismodegib were (R1) toxicity and (R2) disease recurrence. The relationship between DTCR, DTS, TTD, and DFS in the whole population and in R1 subgroup was assessed by Pearson's correlation coefficient (P  < .05) and Bayesian statistics (BF10). Results Sixty-eight BCC patients with a median (m) age of 75.5 years (39-100) were included. Most patients were male (N  = 43, 63%), without Gorlin syndrome (N  = 56, 82%) and with head and neck area as primary site (N  = 51, 75%). After cCR, out of 68 patients, 90% (N = 61/68) discontinued vismodegib: 82% (N  = 50/61) due to toxicity (R1), and 18% (N  = 11/61) due to recurrence (R2). Conversely, 10% (N  = 7/68) continued vismodegib until last follow-up. In the whole population (N  = 68), cCR was achieved with a mDTCR of 180.50 days. DFS showed a significant correlation with DTS (P  < .01, BF10 = 39.2) and TTD (P  < .01, BF10 = 35566), while it was not correlated to DTCR (BF10 < 0.1). The analysis of R1 subgroup (N  = 50) confirmed these results. DFS correlated with DTS in all recurrent patients (N  = 38, r  = 0.44, P  < .01) and in the recurrent patients who stopped vismodegib for toxicity (N  = 26, r  = 0.665, P  < .01). DFS was longer when vismodegib was maintained for >2 months after cCR (mDFS > 2 months, N  = 54 vs. ≤ 2 months, N  = 14: 470 vs. 175 d, P  < .01). Conclusions Our retrospective results suggest that HHIs should be continued after cCR to improve DFS in BCC. [ABSTRACT FROM AUTHOR]

Summary: Recent treatment advancements in multiple myeloma have led to significant improvements in patient outcomes. Maintenance therapy following autologous haematopoietic stem cell transplantation (AHCT) is now standard of care and has been demonstrated to prolong and deepen treatment responses. Currently, lenalidomide remains the single agent that has been approved for maintenance post‐AHCT in Europe and the USA which, if tolerated, is continued until disease progression. The treatment landscape is rapidly expanding however, and the optimal personalised maintenance approach for a patient is becoming more complex. Treatment outcomes for patients with high‐risk disease remain poor and choice of maintenance in this population also remains unclear. This review article evaluates up‐to‐date literature regarding established maintenance approaches. It further analyses ongoing studies exploring maintenance regimens using combination and novel agents, approaches to maintenance in patients with cytogenetic high‐risk disease and minimal residual disease response‐adapted strategies that reflect the current evolving treatment paradigm.

Purpose of Review: The aim of this review is to highlight key published oral immunotherapy (OIT) protocols and post-desensitization strategies for the major food allergens and to cover important concepts to consider when evaluating OIT for food-allergic patients. Shared decision-making should help identify patient and family values which will help influence the type of evidence-based protocol and maintenance strategy to use. Recent Findings: With food OIT emerging as a treatment option, there is a pressing need for patients, physicians, and other providers to have a nuanced understanding of the management choices available to them. There are now randomized controlled trials (RCT) of OIT for peanut, egg, milk, and wheat, and reports of cohorts of patients who have undergone OIT for tree nuts and sesame clinically. The current published protocols contain significant diversity in terms of starting dose, build-up schedule, maintenance dose, and even the product used for desensitization. Emerging data can help direct the long-term maintenance strategy for patients on OIT. Summary: Based on patient and family values elicited through the shared decision-making process, an OIT protocol may be selected that balances the level of desensitization, potential side effects, frequency of clinic visits, and potential to induce sustained unresponsiveness, among other factors. Once maintenance dosing is reached, most patients will need to maintain regular exposure to the food allergen to remain desensitized. The option to transition to commercial food products with equivalent amounts of food protein as the OIT maintenance dose would simplify the dosing process and perhaps improve palatability as well. Less frequent or decreased OIT dosing can provide practical benefits but may affect the level of desensitization and safety for some patients. [ABSTRACT FROM AUTHOR]

Background: The efficacy of subsequent therapy after poly-ADP-ribose polymerase (PARP) inhibitor maintenance treatment has raised concerns. Retrospective studies show worse outcomes for platinum-based chemotherapy after progression of PARP inhibitor-maintenance therapy, especially in BRCA-mutant patients. We aimed to describe subsequent therapy in ovarian cancer patients after PARP inhibitor-maintenance therapy and evaluate their response to treatment. We focused on chemotherapy for patients with a progression-free interval (PFI) of ≥ 6 months after prior platinum treatment, based on BRCA status. Methods: We analyzed real-world data from Peking University Cancer Hospital, subsequent therapy after progression to PARP inhibitor-maintenance therapy for epithelial ovarian cancer between January 2016 and December 2022. Clinicopathological characteristics and treatment outcomes were extracted from medical records. The last follow-up was in May 2023. Results: A total of 102 patients were included, of which 29 (28.4%) had a germline BRCA1/2 mutation and 73 (71.6%) exhibited BRCA1/2 wild-type mutations. The PARP inhibitors used were Olaparib (n = 62, 60.8%), Niraparib (n = 35, 34.3%), and others (n = 5, 4.9%). The overall response rate (ORR) was 41.2%, and the median time to second progression (mTTSP) was 8.1 months (95%CI 5.8–10.2). Of 91 platinum-sensitive patients (PFI ≥ 6 months) after progression to PARP inhibitor-maintenance therapy, 65 patients subsequently received platinum regimens. Among them, 30 had received one line of chemotherapy before PARP inhibitor-maintenance therapy. Analysis of these 30 patients by BRCA status showed an ORR of 16.7% versus 33.3% and mTTSP of 7.1 (95% CI 4.9–9.1) versus 6.2 months (95% CI 3.7–8.3, P = 0.550), for BRCA-mutant and wild-type patients, respectively. For the remaining 35 patients who had received two or more lines of chemotherapy before PARP inhibitor-maintenance therapy, ORR was 57.1% versus 42.9%, and mTTSP was 18.0 (95% CI 5.0–31.0) versus 8.0 months (95% CI 4.9–11.1, P = 0.199), for BRCA-mutant and wild-type patients, respectively. Conclusion: No differences in survival outcomes were observed among patients with different BRCA statuses. Furthermore, for patients who had undergone two or more lines of chemotherapy before PARP inhibitor maintenance therapy, no negative effects of PARP inhibitors on subsequent treatment were found, regardless of BRCA status.

Despite molecular selection, patients (pts) with RAS wildtype mCRC represent a heterogeneous population including diversity in metastatic spread. We investigated metastatic patterns for their prognostic and predictive impact on maintenance therapy with 5‐fluorouracil/folinic acid ± panitumumab. The study population was stratified according to (1) number of involved metastatic sites (single vs multiple organ metastasis), liver‐limited disease vs (2) liver metastasis plus one additional site, and (3) vs liver metastasis plus ≥two additional sites. Kaplan‐Meier method and Cox regressions were used to correlate efficacy endpoints. Single organ metastasis was observed in 133 pts (53.6%) with 102 pts (41.1%) presenting with liver‐limited disease, while multiple organ metastases were reported in 114 pts (46.0). Multiple compared to single organ metastases were associated with less favorable PFS (HR 1.48, 95% CI 1.13‐1.93; P =.004) and OS (HR 1.37, 95% CI 0.98‐1.93; P =.068) of maintenance therapy. While metastatic spread involving one additional extrahepatic site was not associated with clearly impaired survival compared to liver‐limited disease, pts with liver metastasis plus ≥two additional sites demonstrated less favorable PFS (HR 1.92, 95% CI 1.30‐2.83; P <.001), and OS (HR 2.38, 95% CI 1.51‐3.76; P <.001) of maintenance therapy. Pmab‐containing maintenance therapy appeared active in both pts with multiple (HR 0.58; 95% CI, 0.39‐0.86; P =.006) as well as to a lesser numerical extent in pts with single organ metastasis (HR 0.83; 95% CI, 0.57‐1.21; P =.332; Interaction P =.183). These data may support clinical decisions when EGFR‐based maintenance therapy is considered. [ABSTRACT FROM AUTHOR]

The impact of extended steroid administration on patients with autoimmune pancreatitis after a 3-year maintenance period remains poorly understood. This study analyzed the advantage and disadvantage of continuing steroid therapy beyond 3 years. In this retrospective multicenter study across 17 institutions, patients who successfully completed 3 years of maintenance therapy without experiencing relapse were categorized into two groups: the maintenance therapy discontinuation group, who discontinued steroid therapy after the initial 3-year period, and maintenance therapy continuation group, who continued steroid therapy beyond 3 years. The cumulative relapse rate after 3 years of maintenance therapy was the primary outcome. Relapse predictors were compared using the Gray test for cumulative relapse incidence by specific factor. Of 211 patients, 105 experienced no relapse during the 3-year maintenance therapy and were divided into two groups: 69 in the maintenance therapy discontinuation group and 36 in the maintenance therapy continuation group. The relapse rate was lower in the maintenance therapy continuation group than in the maintenance therapy discontinuation group (P = 0.035). Predictors of relapse after 3 years included cessation of maintenance therapy (hazard ratio [HR] = 3.76; 95 % confidence interval [CI] = 1.07–13.3, P = 0.040) and renal involvement (HR = 2.88; 95 % CI = 1.04–7.99, P = 0.042). The maintenance therapy continuation group showed a significantly higher prevalence of macrovascular complications, compared with the maintenance therapy discontinuation group (P = 0.005). Cessation of steroid maintenance therapy and renal involvement were predictors of relapse after 3 years of maintenance therapy. However, the long-term use of steroids may increase the risk of macrovascular complications. [ABSTRACT FROM AUTHOR]

Objective: Previous studies have shown that first-line (1L) maintenance therapy (MT) with poly(ADP-ribose) polymerase inhibitors and/or bevacizumab improves outcomes among patients with advanced ovarian cancer (OC); however, these treatments are underutilized. This study aimed to provide a real-world understanding of MTs among patients with advanced OC who received 1L platinum-based chemotherapy (PBC). Methods: A retrospective chart review using iKnowMed electronic health records to identify patients aged ≥18 years with advanced OC who initiated 1L PBC between January 1, 2018–December 31, 2020. Following 1L PBC, patients could have received MT or active surveillance (AS). Kaplan–Meier methods were used to estimate time to treatment discontinuation (TTD), real-world progression-free survival (rwPFS), and overall survival (OS). Results: Of the 600 chart-reviewed patients included, 239 (39.8 %) received MT and 315 (52.5 %) received AS. Patients who were

Locally advanced or metastatic urothelial carcinoma (aUC) presents a significant challenge with high mortality rates. Platinum-based chemotherapy remains the established frontline standard of care, and a switch-maintenance strategy with immunotherapy has now emerged as a new standard for aUC patients without disease progression, following initial platinum therapy. Examining the treatment patterns is imperative, given the evolving therapeutic landscape. In this study, we conducted a retrospective medical chart review of 17 Canadian oncologists treating patients with aUC to assess unmet needs in Canadian aUC patient care. Data from 146 patient charts were analyzed, revealing important clinical insights about the management of aUC. A substantial proportion of patients (53%) presented with de novo metastatic disease, which was possibly influenced by pandemic-related care disruptions. Variability was evident in the cisplatin eligibility criteria, with a majority (70%) of oncologists utilizing a 50 mL/min threshold. Most favored four cycles of platinum-based chemotherapy to spare the bone marrow for future therapies and prevent patient fatigue. Notably, some eligible patients were kept under surveillance rather than receiving maintenance therapy, suggesting a potential gap in awareness regarding evidence-based recommendations. Furthermore, managing treatment-related adverse events was found to be one of the biggest challenges in relation to maintenance immunotherapy. In conclusion, our findings provide the first comprehensive overview of aUC treatment patterns in Canada following the approval of maintenance immunotherapy, offering insights into the decision-making process and underscoring the importance of evidence-based guidelines in aUC patient management.

Abstract Background The factors that predict the clinical response to ramucirumab plus docetaxel (RD) after first‐line chemoimmunotherapy are unresolved. We explored whether the therapeutic efficacy of prior chemoimmunotherapy could predict the outcome of RD as sequential therapy in patients with advanced non‐small cell lung cancer (NSCLC). Methods Our study comprised 288 patients with advanced NSCLC who received RD as the second‐line treatment after first‐line chemoimmunotherapy at 62 Japanese institutions. Chemoimmunotherapy consisted of a platinum‐based regimen and immune checkpoint inhibitors (ICIs). The association between several variables and the therapeutic outcome of RD was determined via logistic regression analysis. Results Of the 288 patients, 225 (78.1%) received maintenance therapy and 108 (37.5%) received both ICI treatment for >180 days and maintenance therapy. All of 108 patients having ICIs for >180 days received maintenance therapy. Univariate analysis identified performance status, histology (adenocarcinoma), maintenance therapy, and ICI treatment >180 days as significant predictors of better progression‐free survival (PFS) and overall survival (OS) after RD administration. Multivariate analysis confirmed that these factors independently predicted favorable PFS and OS. The therapeutic response and PD‐L1 expression were not closely associated with outcome after RD treatment. In particular, maintenance therapy >4 cycles was more predictive of the better prognosis for RD treatment. Conclusion Extended ICI treatment after chemoimmunotherapy and maintenance therapy enhanced the efficacy of second‐line RD treatment in patients with advanced NSCLC.

The analysis focused on incident patients who received kidney and liver transplants between 2013 and 2019 and evaluated the use of generic of CsA, TAC, and MYC during the 30-day period following discharge. For each type of transplant and immunosuppressive agent, the benefit-risk profile of generic vs branded drugs in a two-year window was estimated by multivariate Cox models (HR; 95% CI). Furthermore, the potential cost savings per person associated with one year of treatment using generics were calculated.Results: The utilization of generic drugs showed a significant increase; over the study years, the proportion of users among kidney recipients ranged from 14.2% to 40.5% for TAC, from 36.9% to 56.7% for MYC, and from 18.2% to 94.7% for CsA. A great variability in generic uptake for region was found. A comparable risk-benefit profile between generic and branded formulations was shown for all immunosuppressors considered. Choosing generic immunosuppressants during maintenance could result in yearly savings of around 2000 euros per person for each therapy ingredient.Conclusion: The study shows an increasing proportion of patients using generic immunosuppressive drugs over time suggesting a growing acceptance of generics within the transplant community and reveals comparable risk-benefit profiles between the generic and branded formulations of TAC, CsA, and MYC. A significant variability in the use of generics immunosuppressive agents was found both at the regional level and among transplant centers and future research should delve into regional prescribing variations.Keywords: transplant, maintenance therapy, tacrolimus, cyclosporine, mycophenolate, uptake generics, risk-benefit profile, sustainability

Introduction: Whether white blood cell (WBC) counts are predictors for the effectiveness of thiopurine treatment in ulcerative colitis (UC) has been inconclusive in previous studies with small sample sizes. We investigated the association between WBC counts and future relapses in UC patients in a large-scale multi-center study. Methods: This retrospective cohort study enrolled a total of 723 UC patients in remission from 33 hospitals and followed up for 3 years. Relapse was defined as a need for treatment intensification. The risk of relapse was compared among patients with the baseline WBC counts

Primary central nervous system lymphoma (PCNSL) is a rare and aggressive disease that originates from lymphocytes and develops in the central nervous system. There is no standard consolidation/maintenance therapy for PCNSL. While there exists a variety of options, the high chance of inferior outcomes for elderly patients and the risk of neurotoxicity requires exploration of alternative options for consolidation/maintenance therapy for PCNSL in the elderly population with CNS lymphoma. We treated one 77-year-old patient with single agent ibrutinib, a Bruton's tyrosine kinase inhibitor that crosses the blood-brain-barrier, as consolidation/maintenance therapy after induction therapy with high-dose methotrexate (HD-MTX) and rituximab plus temozolomide. This treatment resulted in good tolerance, further resolution of a small residue lymphoma, and sustained remission. The patient has completed one year of consolidation/maintenance therapy and is currently under clinical and imaging surveillance. She has survived 27 months without recurrence since diagnosis. This case shows the potential effectiveness of single agent ibrutinib as consolidation/maintenance therapy for PCNSL after induction therapy. More cases are needed to confirm the findings.

Objective: To investigate the efficacy of carelizumab combined with capecitabine for maintenance therapy in first-line treatment of patients with recurrent metastatic nasopharyngeal carcinoma (NPC), and its impact on immune function of patients. Methods 80 patients with recurrent metastasis of NPC who were admitted to Qinzhou First People’s Hospital from January 2020 to January 2022 were selected, the recurrent and metastatic NPC patients were divided into the control group and the observation group according to the random number table method, each group has 40 cases. Both groups received gemcitabine combined with cisplatin chemotherapy, the control group received carelizumab monotherapy maintenance treatment for 1 year after chemotherapy, and the observation group received carelizumab combined with capecitabine maintenance treatment for 1 year after chemotherapy. Differences in efficacy, adverse reactions, and percentage of B lymphocyte subsets and natural killer cells (NK) before and after treatment were compared between the two groups. Results; The objective remission rate (ORR) and disease control rate (DCR) in observation group were higher than those in control group (P＜0. 05). The percentages of CD5+B cells, CD5+CD19+B cells and CD3-CD56+NK cells in peripheral blood after treatment was decreased between the two groups (P＜0. 05), but the percentages of CD5+B cells, CD5+CD19+B cells and CD3-CD56+NK cells in peripheral blood of the observation group were higher than those of the control group after treatment (P＜0. 05). There was no significant difference in the incidence of adverse reactions above grade Ⅲ between the two groups (P＞0. 05). Conclusion: Carelizumab combined with capecitabine in first-line maintenance treatment of recurrent and metastatic NPC could improve clinical efficacy, reduce the impact on cellular immune function, and it was safe and reliable.

Olaparib, a poly(ADP-ribose) polymerase inhibitor, in combination with the antiangiogenic agent bevacizumab, is approved as maintenance therapy for patients with newly diagnosed stage III or IV epithelial ovarian cancer who have homologous recombination deficient tumors with a deleterious or suspected deleterious BRCA mutation and/or genomic instability based on the long-lasting survival benefit observed in the PAOLA-1 trial. Despite treatment with olaparib and bevacizumab showing an acceptable safety profile, the rate of discontinuations due to adverse events was relatively high, and toxicity related to this regimen may restrict its clinical use. Proper management of olaparib/bevacizumab-related adverse events is important for the improvement of quality of life and maximization of the efficacy of maintenance therapy. Here, we summarize the safety results of the PAOLA-1 study, focusing on treatment discontinuation reasons and adverse event profiles. We sought to shed light on toxicity monitoring and prevention, providing concise recommendations for the clinical management of the most relevant side effects. [ABSTRACT FROM AUTHOR]
