Background Widespread antibiotic resistance has sparked interest in the identification of nonantibiotic strategies, particularly probiotics for the prevention of recurrent urinary tract infections (UTIs). We evaluated the effectiveness of prophylactic probiotic supplementation through oral and intravaginal routes in the prevention of recurrent UTIs. Methods This double-blind, placebo-controlled study enrolled 174 premenopausal women with a history of recurrent UTIs and randomized them to 1 of the 4 treatment groups: placebo (G1, oral placebo + vaginal placebo), oral probiotic (G2, oral lactic acid bacteria and bifidobacteria + vaginal placebo), vaginal probiotic (G3, oral placebo + vaginal lactobacilli), and probiotic combination (oral lactic acid bacteria and bifidobacteria + vaginal lactobacilli), for 4 months. Participants were followed up for symptomatic UTIs for 1 year. The primary end points were the number of symptomatic UTIs at 4 months, the proportion of participants with at least 1 symptomatic UTI, and the time to the first symptomatic UTI. Results The incidence of UTI at 4 months in G1, G2, G3, and G4 was 70.4%, 61.3%, 40.9%, and 31.8%, respectively. The mean number of symptomatic UTI recurrences at 4 months was significantly lower (P <.05) in G3 (1.06) and G4 (1.07) compared with G1 (2.1) and G2 (1.63). Further, the time to first symptomatic UTI (days) was significantly longer (P <.05) in G3 (123.8) and G4 (141.8) compared with G1 (69.3) and G2 (71.9). Probiotic supplementations were well tolerated with no serious adverse events. Conclusions Prophylactic supplementation with either vaginal probiotics or in combination with oral probiotics demonstrated effectiveness in preventing recurrent symptomatic UTI episodes.

Investigational drug services need to be organised in a structured approach, especially for sites with a large number of ongoing clinical trials. The aim of this study was to develop a tool to assess the complexity of pharmacy involvement in a sponsored oncology clinical trial. Categorisation into ordinal complexity categories was used to assess the complexity of the clinical trials for consistent pharmacy grant applications. The 15 items of the tool were divided into three sections, and individual item scores were agreed upon among four pharmacists with experience in the conduct of clinical trials at two different centres. A final version of the tool, named Pharm-CAT, was approved. The pharmacists were instructed to use Pharm-CAT to assign a score to each new sponsored trial. To determine the cut-offs for the complexity categories, the scores were sorted in ascending order and the cut-offs corresponding to the first and third tertiles of the score distribution were selected. To verify the reproducibility of the results, Pharm-CAT was applied by two pharmacists independently for each trial. Pharm-CAT proved to be user-friendly. Sixty clinical trials were evaluated and a total of 120 scores were recorded. Low-complexity scores ranged from 0 to 19, medium-complexity scores ranged from 20 to 25, and high-complexity scores were 26 or higher. The average score recorded was 22.88 points. Prospective multicentre validation of Pharm-CAT is needed to confirm its applicability. [ABSTRACT FROM AUTHOR]

In contemporary exploratory phase of oncology drug development, there has been an increasing interest in evaluating investigational drug or drug combination in multiple tumor indications in a single basket trial to expedite drug development. There has been extensive research on more efficiently borrowing information across tumor indications in early phase drug development including Bayesian hierarchical modeling and the pruning-and-pooling methods. Despite the fact that the Go/No-Go decision for subsequent Phase 2 or Phase 3 trial initiation is almost always a multi-facet consideration, the statistical literature of basket trial design and analysis has largely been limited to a single binary endpoint. In this paper we explore the application of considering clinical priorities of multiple endpoints based on matched win ratio to the basket trial design and analysis. The control arm data will be simulated for each tumor indication based on the corresponding null assumptions that could be heterogeneous across tumor indications. The matched win ratio matching on the tumor indication can be performed for individual tumor indication, pooled data, or the pooled data after pruning depending on whether an individual evaluation or a simple pooling or a pruning-and-pooling method is used. We conduct the simulation studies to evaluate the performance of proposed win ratio-based framework and the results suggest the proposed framework could provide desirable operating characteristics.

Based on fieldwork carried out at the Early Drug Development Service of a world‐leading cancer institution, our study sheds lights on decision‐making processes at the stage where decisions are made about which clinical trial to pursue and thus which experimental drugs will feed the growing pipeline of molecularly guided therapies and therapeutic strategies available to treating physicians. The paper shows how such collective decision‐making practices by a translational research unit employ formal tools and ad hoc valuation strategies that interweave technical‐scientific matters of concern with patient‐oriented clinical ones, as part of the institutional assetization of biomedical knowledge production. In the process, decision‐making practices in part define the conditions of possibility for the provision of care in what is increasingly becoming a 'clinic of variants.' They do so by reconfiguring on an evolving basis the socio‐material ecosystem through which precision oncology is enacted as a rapidly evolving assemblage of patients, physicians, research and support staff, protocols, molecular markers, drugs and administrative components.

Simple Summary: Metastatic urothelial carcinoma is sensitive to immunomodulation. Immune checkpoint inhibitors (ICIs) have been FDA approved for use as single agents to treat locally advanced or metastatic urothelial carcinoma (mUC) since 2016. Immunotherapy has a lower incidence of side effects and longer durability of response compared to chemotherapy. Most recently, both the first-line combinations of pembrolizumab plus enfortumab vedotin and of nivolumab plus gemcitabine plus cisplatin showed significant overall survival benefit over prior standard-of-care chemotherapy and will be the fifth and sixth new drug regimens approved for mUC in the past four years. Treatment options for mUC are expected to continue to rapidly evolve. Here, we summarize clinical trials of immunotherapy that have led to the current standard of care for mUC, then review clinical trials testing novel immunotherapeutic approaches. A comprehensive understanding of current clinical trials will enable anticipation of upcoming developments and future research directions for mUC. Urothelial cancer is an immune-responsive cancer, but only a subset of patients benefits from immune checkpoint inhibition. Currently, single-agent immune checkpoint inhibitors (ICIs) and the combination of pembrolizumab with the antibody–drug conjugate enfortumab vedotin are approved to treat patients with metastatic UC (mUC). Approval of first-line nivolumab in combination with gemcitabine and cisplatin is expected imminently. Many treatment approaches are being investigated to better harness the immune system to fight mUC. In this review, we summarize the landmark clinical trials of ICIs that led to their incorporation into the current standard of care for mUC. We further discuss recent and ongoing clinical trials in mUC, which are investigating ICIs in combination with other agents, including chemotherapy, antibody–drug conjugates, tyrosine kinase inhibitors, and novel antibodies. Lastly, we review novel approaches utilizing bispecific antibodies, cellular therapies, and vaccines. The landscape of immunotherapy for mUC is rapidly evolving and will hopefully lead to better outcomes for patients. [ABSTRACT FROM AUTHOR]

Background: The use of suboptimal controls in randomized trials of new cancer drugs can produce potentially unreliable clinical efficacy results over the current standard of care and expose patients to substandard therapy. We aim to investigate the proportion of randomized trials of investigational cancer drugs that used a suboptimal control arm and the number of trial participants at risk of exposure to suboptimal treatments in China. The association between the use of a suboptimal control and concluding statistical significance on the primary endpoint was also examined. Methods and findings: This observational study included randomized controlled trials (RCTs) of cancer drugs that were authorized by specific Chinese institutional review boards between 2016 and 2021, supporting investigational new drug applications of these drugs in China. The proportion of trials that used a suboptimal control arm and the total number of trial participants at risk of exposure to suboptimal treatments were calculated. In a randomized trial for a specific condition, a comparator was deemed suboptimal if it was not recommended by clinical guidelines published in priori or if there existed a regimen with a higher level of recommendation for the indication. The final sample included 453 Phase II/III and Phase III randomized oncology trials. Overall, 60 trials (13.2%) adopted a suboptimal control arm. Among them, 58.3% (35/60) used comparators that were not recommended by a prior guideline for the indication. The cumulative number of trial participants at risk of exposure to suboptimal treatments totaled 18,610 by the end of 2021, contributing 15.1% to the total number of enrollees of all sampled RCTs in this study. After adjusting for the year of ethical approval, region of participant recruitment, line of therapy, and cancer site, second-line therapies (adjusted odds ratio [aOR] = 2.7, 95%CI [1.2, 5.9]), adjuvant therapies (aOR = 8.9, 95% CI [3.4, 23.1]), maintenance therapies (aOR = 5.2, 95% CI [1.6, 17.0]), and trials recruiting participants in China only (aOR = 4.1, 95% CI [2.1, 8.0]) were more likely to adopt a suboptimal control. For the 105 trials with publicly available results, no statistically significant difference was observed between the use of a suboptimal control and concluding positive on the primary endpoint (100.0% [12/12] versus 83.9% [78/93], p = 0.208). The main limitation of this study is its reliance on clinical guidelines that could vary across cancer types and time in assessing the quality of the control groups. Conclusions: In this study, over one-eighth of randomized trials of cancer drugs registered to apply for regulatory approval in China used a suboptimal comparator. Our results highlight the necessity to refine the design of randomized trials to generate optimal clinical evidence for new cancer therapies. In this observational study, Yichen Zhang and colleagues explore how comparator arms are used in randomized oncology trials registered in China. Author summary: Why was this study done?: ■ Using inappropriate controls in randomized trials of new cancer drugs can expose patients to harm and produce potentially unreliable results of clinical efficacy. ■ In November 2021, China's Center for Drug Evaluation issued the Guidance on Clinical Value-Oriented Oncology Drug Research and Development. It stated that an active control arm should be selected with consideration of whether it reflects the optimal treatment in current clinical practices. ■ Previous descriptive analysis showed that oncology trials are expanding in China; however, no literature evaluated the quality of their control arms. What did the researchers do and find?: ■ This observational study reports the annual trend and proportion of 453 Phase II/III and Phase III randomized oncology trials registered in China between 2016 and 2021 that adopted a suboptimal control arm. We also calculated the cumulative number of trial participants at risk of exposure to suboptimal treatments. ■ We observed a fluctuating yet overall upward trend in the number of trials and participants that used a suboptimal comparator during our observation period. Overall, 60 trials adopted a suboptimal control arm and the cumulative number of trial participants at risk of exposure to suboptimal treatments totaled 18,610 by the end of 2021. ■ Trials with a suboptimal control reported higher but statistically non-significant proportions of positive results than those using an optimal control. What do these findings mean?: ■ Trial sponsors, ethical review boards, and oncologists should make collaborative efforts to protect patients from unnecessary harm and drugs with uncertain clinical benefits over the existing standard of care. ■ Regulatory agencies should be cautious when reviewing investigational new drug applications whose supporting trial used a suboptimal control and when making subsequent market authorization decisions. ■ A limitation of this study is the reliance on clinical guidelines that could vary across cancer types and time in assessing the quality of the control groups. Hence, though oncologists and clinical pharmacists were consulted when assessing the sample trials, our results may have inherent subjectivity. [ABSTRACT FROM AUTHOR]

Immune checkpoint inhibitors (PD‐1/PD‐L1 and CTLA‐4 blockade) have revolutionized the treatment landscape in non‐small cell lung cancer (NSCLC). Secondary resistance to immunotherapy (IO), which poses a substantial challenge in clinical settings, occurs in several initial responders. Currently, new treatment approaches have been extensively evaluated in investigational studies for these patients to tackle this difficult problem; however, the lack of consistency in clinical definition, uniform criteria for enrollment in clinical trials, and interpretation of results remain significant hurdles to progress. Thus, our expert panel comprehensively synthesized data from current studies to propose a practical clinical definition of secondary resistance to immunotherapy in NSCLC in metastatic and neoadjuvant settings. In addition to patients who received IO alone (including IO‐IO combinations), we also generated a definition for patients treated with chemotherapy plus IO. This consensus aimed to provide guidance for clinical trial design and facilitate future discussions with investigators. It should be noted that additional updates in this consensus are required when new data is available. [ABSTRACT FROM AUTHOR]

Objective: Available guidelines are ambiguous about safe handling monoclonal antibodies (MABs) and whether or not to use a Closed System Drug-Transfer Device (CSTD). In this article we want to describe a standardized working method on handling MABs in a clinical trial setting. Data Sources: The current workflow at the clinical trial unit of the Ghent University Hospital was critically analyzed, after which an extensive literature review was performed using the National Institute for Occupational Safety and Health Working Group guidelines and the database PubMed (Keywords: monoclonal antibodies, closed system transfer devices, safety guidelines, safe handling, management, administration, (bio)compatibility, volume loss, contamination, clinical trial unit. Period: 2020–2022). Data Summary: Literature data are ambiguous. CSTDs can reduce cross-contamination and minimize exposure to potential hazardous drugs for healthcare professionals. However, in recent years more questions have been raised about their in-use compatibility and their impact on final product quality. This makes the debate on implementing CSTDs a hot topic in daily pharmacy practice and demands a holistic and standardized approach when deciding whether or not to use a CSTD when handling MABs. In a clinical trial setting, where safety data are frequently not available and the compatibility of CSTDs and investigational product is often unknown, this poses additional challenges that need to be taken into account. Conclusion: We developed a flowchart which standardizes the use of a CSTD when handling MABs. It allows other healthcare professionals and clinical trial sponsors to define and evaluate the necessary criteria when standardizing the position of a CSTD in their safe handling procedures.

Purpose Research pharmacy effort required to safely and compliantly manage investigational products (IP) varies between studies. No validated tool exists in the United States to evaluate these differences in effort. The Vizient Pharmacy Research Committee Investigational Drug Services (IDS) Subcommittee previously developed a systematic complexity scoring tool (CST) through expert consensus to assign a complexity score for pharmacy effort. This project seeks to develop and validate complexity categories based on CST scores. Methods Vizient member institutions in IDS assigned a CST complexity score and a perceived complexity category (low, medium, or high) for study initiation and maintenance. Receiver operating characteristic (ROC) curve analysis defined the best CST score cutoff points for each complexity category. Comparing the CST-assigned to the user-perceived complexity category determined whether the CST-assigned complexity category aligned with practitioner assignment. Results A total of 322 responses were used to determine complexity score categories. The AUC values for study initiation and maintenance were 0.79 (P < 0.001) for the low/medium boundary and 0.80 (P < 0.001) for the medium/high boundary, suggesting the performance of the CST is good. The agreement between CST-assigned and user-perceived complexity categories was 60% for study initiation and 58% for maintenance. The Kendall rank correlation coefficient between the raters and ROC categories was strong, with a value of 0.48 for study initiation and 0.47 for maintenance. Conclusion Development of the CST allows IDS pharmacies to objectively measure the complexity of clinical trials, which is a significant step towards assessing workload and guiding resource allocation.

Pediatric drug development has many unique challenges, one of which is the evaluation of growth and development changes in children that are expected and are not due to the study intervention. Children grow and mature at different pace. The potential impact of the drug could vary with the developmental age of the participants receiving the treatment. For example, sexual maturation is a critical consideration in children of age 10 and above, but not in younger age groups. How the investigational drug impacts children is ultimately a risk-benefit consideration. In this paper, practical considerations and recommendations are provided on how to assess growth and development based on data collected from clinical trials in pediatric patients. The endpoints and measures related to growth, sexual maturation and neurocognitive development are discussed. Basic analysis approaches are recommended. [ABSTRACT FROM AUTHOR]

Over the past 30 years, progress has been made in increasing women's representation in clinical research. However, women continue to be underrepresented in phase I clinical trials—those trials that test the safety and tolerability of investigational drugs, often on healthy individuals. As sex‐based differences in adverse drug reactions are often linked to drug dose, pivotal safety information in phase I trials is often insufficiently—and inequitably—captured for females. Yet there has been little attention to how clinical investigators and those charged with overseeing the ethical conduct of these trials perceive the barriers to women's inclusion in phase I trials. To address this gap, we report on 22 interviews with U.S. phase I investigators and institutional review board (IRB) members. Our findings indicate that although these investigators and IRB members acknowledged the importance of including women in clinical trials, they justified women's exclusion from phase I trials by citing the need to manage their reproductive potential. In particular, we identified four key themes that informants used to warrant women's exclusion from phase I trials: the structure of the drug‐development system itself, fears about risks to potential fetuses, distrust of women to prevent pregnancy, and concerns about risks and burdens to institutions from resulting pregnancies. We argue that these rationales reflect structural and cultural barriers to women's inclusion in clinical research that ultimately fail to respect female research participants as persons, highlighting the need for broad‐based solutions.

Fezolinetant (VEOZAH™) is an oral, small molecule, neurokinin 3 receptor (NK3R) antagonist, which is being developed by Astellas Pharma Inc. for the treatment of moderate to severe vasomotor symptoms (VMS) or hot flashes due to menopause. Inhibiting NK3R-mediated signalling in the central nervous system is a non-hormonal strategy to modulate the activity of neurones that are associated with thermoregulation, thereby reducing the frequency and severity of VMS. Fezolinetant received its first approval in the USA in May 2023 for the treatment of moderate to severe VMS due to menopause. This article summarizes the milestones in the development of fezolinetant leading to this first approval in this indication. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Patients with chronic scrotal content pain (CSCP) lack effective, noninvasive treatment options. We aimed to determine the local and systemic safety, tolerability, pharmacokinetics (PK), and efficacy of a long-lasting local anesthetic in patients with CSCP. METHODS: This was a prospective, single-center, open-label, single-arm, phase 1, doseescalating trial completed between October 2019 and March 2021. Twelve patients ≥19 years old with unilateral scrotal pain lasting ≥3 months reporting an average maximum pain score over seven days of ≥4 on a 0-10 numerical rating scale (NRS) were included. Patients underwent a test spermatic cord block and those reporting a decrease of ≥2 points were included. The investigational drug, ST-01 (sustained-release lidocaine polymer solution), is a long-acting injection of lidocaine around the spermatic cord. Subjects were provided a NRS dairy and recorded their NRS score until day 28. The Chronic Epididymitis Symptom Index (CESI) was completed on days 0, 7, 14, and 28. All patients underwent an examination and assessment for adverse events (AE) on days 0, 1, 7, 14, and 28. Exploratory statistical hypothesis testing was planned for this study due to its investigative nature. RESULTS: There were no serious adverse events (SAEs) reported. All subjects reported at least one treatment-emergent adverse event (TEAE); 83% of related AEs were injection-site reactions consisting of swelling and bruising. NRS was reduced across all cohorts between baseline and end of study. CONCLUSIONS: This study provides evidence that the novel ST-01 treatment is safe and well-tolerated. [ABSTRACT FROM AUTHOR]

As clinical use of currently available opioid analgesics is often impeded by dose-limiting adverse effects, such as abuse liability and respiratory depression, new approaches have been pursued to develop safe, effective, and non-addictive pain medications. After the identification of the nociceptin/orphanin FQ (N/OFQ) peptide (NOP) receptor more than 25 years ago, NOP receptor-related agonists have emerged as a promising target for developing novel and effective opioids that modulate the analgesic and addictive properties of mu-opioid peptide (MOP) receptor agonists. In this review, we highlight the effects of the NOP receptor-related agonists compared with those of MOP receptor agonists in experimental rodent and more translational non-human primate (NHP) models and the development status of key NOP receptor-related agonists as potential safe and non-addictive analgesics. Several lines of evidence demonstrated that peptidic and non-peptidic NOP receptor agonists produce potent analgesic effects by intrathecal delivery in NHPs. Moreover, mixed NOP/MOP receptor partial agonists (e.g., BU08028, BU10038, and AT-121) display potent analgesic effects when administered intrathecally or systemically, without eliciting adverse effects, such as respiratory depression, itch behavior, and signs of abuse liability. More importantly, cebranopadol, a mixed NOP/opioid receptor agonist with full efficacy at NOP and MOP receptors, produces robust analgesic efficacy with reduced adverse effects, conferring promising outcomes in clinical studies. A balanced coactivation of NOP and MOP receptors is a strategy that warrants further exploration and refinement for the development of novel analgesics with a safer and effective profile.

Pregnant people have traditionally been excluded from therapeutic research by restrictions intended for fetal protection. Despite a movement toward inclusion, concerns for the feasibility and safety of including pregnant people in studies continue to limit this research. This article reviews the history of research guidelines in pregnancy and illustrates ongoing challenges, as seen in the development of vaccines and therapies during the coronavirus disease 2019 pandemic and investigation of statins for preeclampsia prevention. It explores new approaches that may be used to improve therapeutic research in pregnancy. A major cultural shift is needed to balance potential maternal and/or fetal risks with potential benefits from participation in research, as well as harm from withholding treatment or providing one that is not evidence‐based. Finally, it is important to honor maternal autonomy in decision‐making regarding participation in clinical trials. [ABSTRACT FROM AUTHOR]

Purpose This study is an analysis of the changes to workload and operations of UNC Health's investigational drug service (IDS) brought about by the coronavirus disease 2019 (COVID-19) pandemic. Methods Workload statistics were collected and analyzed for trend changes to illustrate operational changes necessitated by the COVID-19 pandemic within the IDS pharmacy at UNC Health. Results Multiple workload metrics declined at the beginning of the COVID-19 pandemic, followed by an increase in the metrics for many categories as the pandemic continued. Notably, monthly inventory added initially decreased by 37.5%, later leveling off but showing increased variability. Fills dispensed and monitoring visits both decreased by 34.5% from the first quarter (Q1) to Q2 of 2020. Both metrics returned to or slightly exceeded prepandemic levels by the end of the study period in March 2021. Patient enrollment decreased 76% from February to May 2020 before dramatically increasing in Q3 of 2020 and Q1 of 2021 with the initiation of COVID-19 vaccine studies. The average time to study startup increased for trials not related to COVID-19 and decreased for COVID-19–related trials. There has been no major impact on the number of open protocols throughout the course of the pandemic. Conclusion Despite initial decreases in workload following the start of the COVID-19 pandemic, IDS operations returned to and, in some cases, exceeded prepandemic levels. [ABSTRACT FROM AUTHOR]

Background: Cardiovascular disease remains the leading cause of death worldwide and brings a heavy burden. However, the development of cardiovascular drug clinical trials in China remains unclear. The purpose of this study was to identify the status of clinical trials of cardiovascular drugs in China and provide a reference for stakeholders' decisions. Methods: Data were collected from the National Medical Products Administration (NMPA) Registration and Information Disclosure Platform for Drug Clinical Trials before July 1, 2021. We collected all information about clinical trials, including study design, and leading unit. The landscape of cardiovascular drug clinical trials was analyzed by the characteristics, time trends, indications, and geographical distribution. Results: A total of 1666 cardiovascular drug clinical trials were launched from 2009 to 2021 in China. Bioequivalence/bioavailability studies accounted for the most significant proportion (1099 [65.97%]), followed by phase I (296 [17.77%]), phase III (135 [8.10%]), phase II (118 [7.08%]), and phase IV trials (18 [1.08%]). Initiated trials increased by 23.45% annually from 2009 to 2020. Trials of hypertension accounted for the most significant number, followed by coronary heart disease, dyslipidemia, and heart failure. Most trials (66.68%) were conducted in eastern China, followed by the central and western regions, showing a regional disparity as leading units. Conclusion: Despite the significant progress of cardiovascular drug clinical trials in China, there is still a long way to innovative drug research and development, requiring persistent policy support and more investment. Innovation, quality, efficiency, and equity need to be carefully considered by all stakeholders in clinical trials. [ABSTRACT FROM AUTHOR]

Purpose Training represents a considerable portion of research activities and is vastly different for each clinical trial. This variation is partially explained by the lack of detailed regulations surrounding training procedures, which hinders the ability of investigational drug service (IDS) staff to plan their workload. The aim of this study was to quantify the workload associated with trial-specific training of IDS staff. The secondary aim was to identify the factors associated with training complexity. Methods A retrospective study was carried out in the IDS of a mother and child university hospital. Trial-specific documents on which the pharmacy staff was trained were analyzed. Workload was calculated by measuring reading time. The readability of each document was determined by the Flesch Reading Ease score. The complexity of the trials was established using the scoring method of Calvin-Lamas et al. The influence of the following factors on training was assessed by analysis of variance: sponsor type, research phase, and research focus by medical specialty. Results A total of 93 clinical trials and 433 documents were included. Investigator's brochures were the longest (a mean [SD] of 107 [46] pages; P < 0.0001) and most difficult documents to read (mean [SD] readability score, 25.5 [4.4]; P < 0.0001). Trials with industry sponsors required a significantly longer overall reading time (mean [SD], 12.26 [6.72] hours; P < 0.0001). On average, a mean (SD) of 9.42 (7.16) hours of reading were necessary to train one employee for a clinical trial. Conclusion This study is the first to document reading time necessary for training of IDS staff. The training workload varied by sponsor type, while the research phase and medical specialty had little impact. IDS units would benefit from a tool that could identify complex trials.

People with sickle cell disease (SCD) are living longer than ever before, with the median survival increasing from age 14 years in 1973, beyond age 40 years in the 1990s, and as high as 61 years in recent cohorts from academic centers. Improvements in survival have been attributed to initiatives, such as newborn screening, penicillin prophylaxis, vaccination against encapsulated organisms, better detection and treatment of splenic sequestration, and improved transfusion support. There are an estimated 100,000 people living with SCD in the United States and millions of people with SCD globally. Given that the number of older adults with SCD will likely continue to increase as survival improves, better evidence on how to manage this population is needed. When managing older adults with SCD (defined herein as age ≥ 40 years), healthcare providers should consider the potential pitfalls of extrapolating evidence from existing studies on current and emerging therapies that have typically been conducted with participants at mean ages far below 40 years. Older adults with SCD have historically had little to no representation in clinical trials; therefore, more guidance is needed on how to use current and emerging therapies in this population. This article summarizes the available evidence for managing older adults with SCD and discusses potential challenges to using approved and emerging drugs in this population. [ABSTRACT FROM AUTHOR]

Childhood-onset systemic lupus erythematosus (SLE) is characterized by increased rates of kidney involvement, termed lupus nephritis. Despite the significant morbidity and mortality associated with this disease, lupus nephritis trials have been plagued by repeated failures to meet clinical endpoints. However, improvements in trial design and the development of targeted approaches have begun to yield promising results, including two new FDA-approved lupus nephritis treatments since 2020. These include belimumab, a monoclonal antibody targeting the B cell survival cytokine BAFF (B cell activating factor), and voclosporin, a cyclosporin analog with improved pharmacokinetic characteristics. In this review, we will summarize the data supporting regulatory approval for these agents in lupus nephritis and highlight ongoing clinical trials targeting the diverse immunologic drivers of renal inflammation in SLE. While pediatric patients remain underrepresented in lupus clinical trials, given the increased severity of childhood-onset SLE and need for long-term protection from kidney damage, we anticipate the need for off-label use of these targeted therapies in the pediatric population. Future studies are needed to define optimal patient selection, drug combinations, and treatment duration in pediatric lupus nephritis. [ABSTRACT FROM AUTHOR]

Given the past two decades of over 40 failed trials of amyloid-lowering therapies in Alzheimer's Disease (AD), many of which succeeded in lowering amyloid as designed, we present an ethical argument for emptying the drug pipeline of tests of amyloid-lowering agents so as to end the historical dominance of the amyloid-reducing therapeutic approach in AD.

Drawing on ethical and legal frameworks in the Netherlands, the United States and France, we examine whether physicians are expected to inform patients about potentially relevant opportunities for expanded access to investigational drugs. While we found no definitive legal obligation, we argue that physicians have a moral obligation to discuss opportunities for expanded access with patients who have run out of treatment options to prevent inequality, to promote autonomy, and to achieve beneficence.

Background Traditional end points used in registrational randomized, controlled trials (RCTs) often do not allow for complete interpretation of the full range of potential clinical outcomes. Desirability of outcome ranking (DOOR) is an approach to the design and analysis of clinical trials that incorporates benefits and risks of novel treatment strategies and provides a global assessment of patient experience. Methods Through a multidisciplinary committee of experts in infectious diseases, clinical trial design, drug regulation, and patient experience, we developed a DOOR end point for infectious disease syndromes and demonstrated how this could be applied to 3 registrational drug trials (ZEUS, APEKS-cUTI, and DORI-05) for complicated urinary tract infections (cUTIs). ZEUS compared fosfomycin to piperacillin/tazobactam, APEKS-cUTI compared cefiderocol to imipenem, and DORI-05 compared doripenem to levofloxacin. Using DOOR, we estimated the probability of a more desirable outcome with each investigational antibacterial drug. Results In each RCT, the DOOR distribution was similar and the probability that a patient in the investigational arm would have a more desirable outcome than a patient in the control arm had a 95% confidence interval containing 50%, indicating no significant difference between treatment arms. DOOR facilitated improved understanding of potential trade-offs between clinical efficacy and safety. Partial credit and subgroup analyses also highlight unique attributes of DOOR. Conclusions DOOR can effectively be used in registrational cUTI trials. The DOOR end point presented here can be adapted for other infectious disease syndromes and prospectively incorporated into future clinical trials. [ABSTRACT FROM AUTHOR]

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) accounts for the vast majority of cases of pancreatic cancer and is a lethal cancer that is often diagnosed as late-stage disease with a historically poor prognosis, as reflected in its status as the third leading cause of cancer-related deaths in the United States. OBJECTIVE: To review the landmark clinical trials of approved chemotherapy regimens, immunotherapies, and targeted therapies for PDAC and discuss the notable investigational agents currently in clinical trials that have shown survival benefits in patients with PDAC. DISCUSSION: Chemotherapy regimens, such as FOLFIRINOX (fluorouracil, leucovorin, irinotecan, and oxaliplatin) or nab-paclitaxel plus gemcitabine, have improved survival in phase 3 trials and are recommended as a first-line treatment for locally advanced or metastatic PDAC. In patients with recurrent disease, salvage chemotherapy has either limited or conflicting data. Approved immunotherapies and targeted therapies include pembrolizumab, olaparib, and 3 tyrosine kinase inhibitors (larotrectinib, entrectinib, and erlotinib), but all targeted therapies are limited in clinical use and are reserved for patient populations with specific genetic mutations. The therapeutic approaches currently in early-phase development for PDAC include dual immune checkpoint inhibition, monoclonal antibodies, cellular therapy, oncolytic adenoviruses, oligonucleotides, and multiple small-molecule inhibitors. Combinations of immunotherapies that target the programmed cell death (PD)-1 or PD ligand 1 are being explored in the induction and maintenance settings. Single agents under investigation are often combined with standard chemotherapy in the treatment of locally advanced or metastatic PDAC. The Precision Promise adaptive clinical trial platform is an innovative and efficient approach to testing multiple novel therapies simultaneously. CONCLUSION: Of the notable investigational agents for PDAC, early clinical data demonstrate improvements in tumor response and survival benefit in locally advanced or metastatic disease. Emerging immunotherapies and targeted therapies are at the forefront of drug development and may transform the approach to the treatment of patients with PDAC. [ABSTRACT FROM AUTHOR]

Background: The current mainstay treatment of perimenstrual acne consists of systemic hormonal therapies, which can be problematic due to their side effects, stigma, or pill burden. Topical treatments are often used as well; however, data on their efficacy in treating this type of hormonal acne are limited.Objective: We sought to evaluate the efficacy and tolerability of clindamycin phosphate and benzoyl peroxide 1.2%/3.75% combination gel in treating perimenstrual acne in adult women.Methods: The single-group interventional pilot study was performed on 22 adult female subjects with perimenstrual acne. The subjects applied the investigational drug daily and were assessed every 14 days for a total of 99 days. Treatment success was evaluated by the investigators using the acne physician global assessment (PGA) scoring system. Drug tolerability assessment was based on the subject-reported adverse events, as well as physician-evaluated erythema, scaling, and dryness.Results: The study demonstrated a significant improvement in PGA score and lesion count, as well as patient-reported outcomes. The medication was well-tolerated in all subjects.Limitations: Limited sample size; lack of concurrent comparison group.Conclusion: Clindamycin phosphate and benzoyl peroxide 1.2%/3.75% combination gel presents an important topical option for perimenstrual acne.

Chronic infection with hepatitis B virus (HBV) represents one of the main causes of the development of cirrhosis and its complications. Treatment with potent third-generation nucleos(t)ide analogues (NUCs) results in >99% HBV DNA undetectability, and prevents fibrosis progression and liver-related complications. However, NUCs are not able to induce the so-called functional cure, which is hepatitis B surface antigen (HBsAg) loss and anti-HBs seroconversion. Consequently, NUC treatment is currently intended as being long-term or lifelong, resulting in the need for clinical monitoring and potentially suffering from compliance issues. Consequently, drug development in HBV has the goal of developing new agents in order to achieve a functional cure for HBV. Currently, the three main strategies include the following: inhibition of viral replication, inhibition of viral antigens, and immune modulation. This review summarizes the most recent updates concerning HBV compounds among these three main classes. [ABSTRACT FROM AUTHOR]

The article reports that Pfizer Inc. announced positive top-line data from the Phase 3 clinical trial MATISSE (Maternal Immunization Study for Safety and Efficacy) investigating its bivalent RSV prefusion vaccine candidate, RSVpreF or PF-06928316 when administered to pregnant participants to help protect their infants from RSV disease after birth.

Simple Summary: Bromodomain and extraterminal domain (BET) proteins can regulate cancer-related genes to make tumors grow. BMS-986158, an experimental anticancer therapy, blocks BET protein function. We researched BMS-986158′s potential anticancer effects, side effects, what happens to BMS-986158 in the body, and whether treatment causes any changes in gene activity. To determine the proper dose, 5 different doses were tested using 3 schedules (days taking and not taking therapy). Among 83 patients across all dose schedules, BMS-986158 was generally well tolerated. The most common side effects were diarrhea (43% of patients) and lower platelet cell numbers (blood clotting cells; 39%). Schedule A (cycles of 5 days on and 2 days off therapy) provided stable levels of BMS-986158 in the blood and showed some preliminary anticancer effects, with 30% of patients showing a clinical benefit (a period without meaningful tumor growth in 12 patients and tumor shrinkage by at least 30% in 2 patients). This phase 1/2a, open-label study (NCT02419417) evaluated the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics of BMS-986158, a selective bromodomain and extraterminal domain (BET) inhibitor. Dose escalation was performed with 3 BMS-986158 dosing schedules: A (5 days on, 2 days off; range, 0.75–4.5 mg), B (14 days on, 7 days off; 2.0–3.0 mg), and C (7 days on, 14 days off; 2.0–4.5 mg). Eighty-three patients were enrolled and received ≥1 BMS-986158 dose. Diarrhea (43%) and thrombocytopenia (39%) were the most common treatment-related adverse events (TRAEs). A lower incidence of TRAEs was found with schedules A (72%) and C (72%) vs. B (100%). Stable disease was achieved in 12 (26.1%), 3 (37.5%), and 9 (31.0%) patients on schedules A, B, and C, respectively. Two patients on schedule A with a 4.5-mg starting dose (ovarian cancer, n = 1; nuclear protein in testis [NUT] carcinoma, n = 1) experienced a partial response. BMS-986158 demonstrated rapid-to-moderate absorption (median time to maximum observed plasma concentration, 1–4 h). As expected with an epigenetic modifier, expression changes in select BET-regulated genes occurred with BMS-986158 treatment. Schedule A dosing (5 days on, 2 days off) yielded tolerable safety, preliminary antitumor activity, and a dose-proportional PK profile. [ABSTRACT FROM AUTHOR]

The Food and Drug Administration uses expedited approval of drugs to speed the development and assessment of drugs that address unmet needs related to serious or life-threatening conditions. Drugs approved via this route rely on surrogate endpoints or other clinical indicators that are not direct measures of benefits to patients, such as survival or quality of life. Companies are required to conduct a clinical trial confirming that a drug provides long-term benefits that are clinically meaningful, but prompt completion of these trials frequently does not occur. Theory suggests that because confirmatory trials reduce uncertainty, they should provide an economic reward in the form of higher prices for a positive finding. We used a sample of physician-administered cancer drugs and data on average sales price to test this hypothesis. We found no significant relationship between confirmatory trial completion with a positive outcome and elevated prices. This represents a failure of the market to reward reduced uncertainty about a cancer drug's true benefits. This inefficiency would be mitigated if major payers such as Medicare built price schedules that directly rewarded completion of confirmatory trials. More completed trials would ensure that patients are receiving truly effective chemotherapies and not suffering the adverse effects of drugs that are ultimately not effective. [ABSTRACT FROM AUTHOR]

Background: The low expectation of clinical benefit from phase 1 cancer therapeutics trials might negatively affect patient and physician participation, study reimbursement, and slow the progress of oncology research. Advances in cancer drug development, meanwhile, might have favourably improved treatment responses; however, little comprehensive data exist describing the response and toxicity associated with phase 1 trials across solid tumours. The aim of the study is to evaluate the trend of toxicity and response in phase 1 trials for solid tumours over time.Methods: We analysed patient-level data from the Cancer Therapy Evaluation Program of the National Cancer Institute-sponsored investigator-initiated phase 1 trials for solid tumours, from Jan 1, 2000, to May 31, 2019. We assessed risks of treatment-related death (grade 5 toxicity ratings possibly, probably, or definitely attributable to treatment), all on-treatment deaths (deaths during protocol treatment regardless of attribution), grade 3-4 toxicity, and proportion of overall response (complete response and partial response) and complete response rate in the study periods of 2000-05, 2006-12, and 2013-2019, and evaluated their trends over time. We also analysed cancer type-specific and investigational agent-specific response, and analysed the trend of response in each cancer type over time. Univariate associations of overall response rates with patients' baseline characteristics (age, sex, performance status, BMI, albumin concentration, and haemoglobin concentration), enrolment period, investigational agents, and trial design were assessed using risk ratio based on the modified Poisson regression model.Findings: We analysed 465 protocols that enrolled 13 847 patients using 261 agents. 144 (31%) trials used a monotherapy and 321 (69%) used combination therapies. The overall treatment-related death rate was 0·7% (95% CI 0·5-0·8) across all periods. Risks of treatment-related deaths did not change over time (p=0·52). All on-treatment death risk during the study period was 8·0% (95% CI 7·6-8·5). The most common grade 3-4 adverse events were haematological; grade 3-4 neutropenia occurred in 2336 (16·9%) of 13 847 patients, lymphopenia in 1230 (8·9%), anaemia in 894 (6·5%), and thrombocytopenia in 979 (7·1%). The overall response rate for all trials during the study period was 12·2% (95% CI 11·5-12·8; 1133 of 9325 patients) and complete response rate was 2·7% (2·4-3·0; 249 of 9325). Overall response increased from 9·6% (95% CI 8·7-10·6) in 2000-05 to 18·0% (15·7-20·5) in 2013-19, and complete response rates from 2·5% (2·0-3·0) to 4·3% (3·2-5·7). Overall response rates for combination therapy were substantially higher than for monotherapy (15·8% [15·0-16·8] vs 3·5% [2·8-4·2]). The overall response by class of agents differed across diseases. Anti-angiogenesis agents were associated with higher overall response rate for bladder, colon, kidney and ovarian cancer. DNA repair inhibitors were associated with higher overall response rate in ovarian and pancreatic cancer. The rates of overall response over time differed markedly by disease; there were notable improvements in bladder, breast, and kidney cancer and melanoma, but no change in the low response of pancreatic and colon cancer.Interpretation: During the past 20 years, the response rate in phase 1 trials nearly doubled without an increase in the treatment-related death rate. However, there is significant heterogeneity in overall response by various factors such as cancer type, investigational agent, and trial design. Therefore, informed decision making is crucial for patients before participating in phase 1 trials. This study provides updated encouraging outcomes of modern phase 1 trials in solid tumours.Funding: National Cancer Institute. [ABSTRACT FROM AUTHOR]

Felcisetrag (formerly known as TAK‐954) is a selective serotonin receptor agonist under investigation for use in patients with postoperative gastrointestinal dysfunction. The safety, tolerability, and pharmacokinetics (PK) of intravenous (i.v.) felcisetrag have been studied, but little is known about the effect of hepatic impairment on the PK of the drug. This phase 1, non‐randomized, open‐label study compared the PK of a single 60‐minute i.v. infusion of felcisetrag between healthy individuals (n = 8) and patients with moderate (n = 10) or severe (n = 7) hepatic impairment. The primary study end points were the total and free maximum observed plasma concentration of felcisetrag at the end of infusion (Cmax), area under the concentration–time curve (AUC) from time 0 to the time of the last quantifiable concentration (AUClast), and AUC from time 0 to infinity (AUCinf). Concentration–time profiles of felcisetrag were similarly shaped between groups but revealed lower concentrations of total plasma felcisetrag with increasing severity of hepatic impairment, whereas concentrations of free felcisetrag increased. The ratios of AUClast and AUCinf for patients with severe hepatic impairment were up to 29.3% lower for total felcisetrag and up to 29.2% higher for free felcisetrag than found in healthy individuals (P <.05). Infusions were well tolerated with no discontinuations, severe adverse events, or deaths during the study. Overall, the effect of hepatic impairment on exposure to felcisetrag was minimal, suggesting that dose adjustment may be unnecessary in patients with hepatic impairment. [ABSTRACT FROM AUTHOR]

The use of placebo concurrent control (placebo‐controlled) is the most rigorous method of evaluating the safety and efficacy of investigational treatments. However, the use of a placebo group in pediatric product development can be challenging due to ethical considerations and potential differences in placebo response rates between adults and children. This study reports the US Food and Drug Administration's experience with placebo response rates in the pediatric population. Products studied under the Best Pharmaceuticals for Children Act and the Pediatric Research Equity Act between 2012 and 2020 were screened. Study characteristics including study type, primary efficacy endpoint(s), placebo response rates for the primary efficacy endpoint(s) and studied age range were collected. A total of 71 drug products used a placebo‐controlled trial. Of these, thirteen products had an identical study design and trial characteristics including the primary efficacy endpoints between pediatric and adult studies. Fifteen products were studied in trials with identical study design but only different primary efficacy endpoints in pediatric and adult populations. Ten products had combined adolescent and adult trials with separate pediatric trials in younger age groups. In each of these cases, the pediatric placebo response was greater, for some trials, and less, for other trials, than the adult placebo response. The pediatric placebo response can vary within an age group for a drug product. Future studies should examine the factors leading to a similarity or dissimilarity in placebo response between pediatric patients and adults. [ABSTRACT FROM AUTHOR]

The relevance of the study is conditioned upon the fact that outbreaks of anthrax are periodically recorded on the territory of Ukraine, not only in ruminants, but also in pigs, fur animals, dogs, and people. The purpose of the study is to investigate the protective properties of the experimental vaccines and the abacillary vaccine "Antracol" and to prove the immunogenic effect of the extracellular toxin from the B. anthracis K-79 Z strain. Cultures of vaccine strains of anthrax were used for the experiments: B. anthracis 55, B. anthracis SB, B. anthracis K-79 Z and the "Antracol" vaccine (experimental development). Microbiological, clinical-biological, and biotechnological research methods were used in the study. The protective effect was investigated on guinea pigs (Cavia porcellus). An acute experiment was performed with a virulent strain B. anthracis 92 Z. Exotoxin was obtained from the specified cultures. The titre of the exotoxin was found in the disk precipitation reaction. The highest result regarding exotoxin production was recorded in B. anthracis K-79 Z 1 : 128 with a total protein concentration of 0.19 mg/ml, while the exotoxin of B. anthracis strain 55 with a titre of 1 : 32 showed a high total protein concentration of 0.4 mg/ml. The effect of B. anthracis exotoxins on the body was investigated by administering them to laboratory animals in different titres of exotoxins, followed by infection with the pathogenic strain B. anthracis 92 Z. The exotoxin of the vaccine strain B. anthracis K-79 Z in a titre of 1 : 64-1 : 128 shows the best protective properties against the pathogenic strain. It was found that the vaccine strains of B. anthracis SB and B. anthracis K-79 Z have the same level of protection of laboratory animals during experimental infection, which is 60%, while the vaccine from the strain B. anthracis 34F2 showed a level of protection of 20%. Based on the results of the study, it was found appropriate to use exotoxin B. anthracis in the development of prophylactic preparations against anthrax. The research results can be used by scientists and specialists in the field of veterinary medicine to develop new and improve the available vaccines for effective anthrax prevention [ABSTRACT FROM AUTHOR]

Simple Summary: Pancreatic ductal adenocarcinoma (PDAC) is a common type of cancer originating from the pancreatic glands and is characterized by a rapidly progressive course and a dismal prognosis. Currently, chemotherapy is the cornerstone of treatment that has modest efficacy. Targeted treatment options are rapidly evolving with the growing understanding of pathobiological underpinnings of tumorigenesis, progression, and treatment resistance mechanisms. Combination strategies targeting multiple signaling pathways supporting tumor growth and propagation are active areas of contemporary research that will likely transform the treatment paradigm of pancreatic cancer. Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy characterized by nonspecific presenting symptoms, lack of a screening test, rapidly progressive clinical course, and presentation with an advanced-stage disease in the majority of patients. PDAC is essentially a systemic disease irrespective of the initial stage, as most patients with non-metastatic PDAC undergoing curative-intent treatment eventually experience metastatic relapse. Currently, cytotoxic chemotherapy remains the cornerstone of treatment in patients with advanced disease. However, the current standard treatment with multiagent chemotherapy has modest efficacy and results in median overall survival (OS) of less than a year and a 5-year OS of about 10%. The pathobiology of PDAC poses many challenges, including a unique tumor microenvironment interfering with drug delivery, intratumoral heterogeneity, and a strongly immunosuppressive microenvironment that supports cancer growth. Recent research is exploring a wide range of novel therapeutic targets, including genomic alterations, tumor microenvironment, and tumor metabolism. The rapid evolution of tumor genome sequencing technologies paves the way for personalized, targeted therapies. The present review summarizes the current chemotherapeutic treatment paradigm of advanced PDAC and discusses the evolving novel targets that are being investigated in a myriad of clinical trials.

Bayesian methods quantify and interpret the therapeutic effects of investigational drugs based on probability statements of the posterior distribution. However, the basic principle underlying the use of Bayesian methods in registration trials for new drug applications in Japan has not been adequately discussed. Motivated by the two drug approval systems for early approval recently enacted in Japan, we present our perspectives on the application of the Bayesian approach in registration trials in Japan. These are based on discussions among academic, industry, and regulatory experts at invited workshops. Based on the aforementioned early approval systems, we discuss putative common regulatory issues related to the use of the Bayesian approach and introduce instances of clinical trials in which the Bayesian approach is expected to be used. This article provides a well‐defined premise for the discussion between industry and regulatory agencies on the use of Bayesian approaches for early drug approval in Japan. [ABSTRACT FROM AUTHOR]

Despite the importance of including diverse populations in biomedical research, women remain underrepresented as healthy volunteers in the testing of investigational drugs in Phase I trials. Contributing significantly to this are restrictions that pharmaceutical companies place on the participation of women of so-called childbearing potential. These restrictions have far-reaching effects on biomedical science and public health. Using 191 interviews collected over three years, this article explores the experiences of 47 women who navigate restrictions on their participation in U.S. Phase I trials. Women in this context face a number of contradictory criteria when trying to enroll, which can curtail their participation, justify additional surveillance, and deny pregnant women reproductive agency. The pharmaceutical industry's putative protections for hypothetical fetuses exacerbate inequalities and attenuate a thorough investigation of the safety of their drugs for public consumption. We use the framework of "anticipatory motherhood" within a gendered organizations approach to make sense of women's experiences in this context. [ABSTRACT FROM AUTHOR]

Blockchain is a novel data architecture characterized by a chronological sequence of blocks in a decentralized manner. We aimed to evaluate the real‐world feasibility of a blockchain‐based dynamic consent platform (METORY) in a decentralized and multicenter trial. The study consisted of three visits (i.e., screening and 2 follow‐up visits) with a 2‐week interval. Each subject was required to report the self‐measured body temperatures and take a virtual investigational drug by entering the unique drug code on the application. To simulate real‐world study settings, two major (i.e., changes in the schedule of body temperature measurement) and three minor protocol amendments (i.e., nonsignificant changes without any changes in the procedures) were set. Overall study completion rates, proportion of consent, and response time to each protocol amendment and adherence were evaluated. A total of 60 subjects (30 in each center) were enrolled in two study centers. All subjects completed the study, and the overall proportion of consent to each protocol amendment was 95.7 ± 13.7% (mean ± SD), with a median response time of 0.2 h. Overall, subjects took 90.8% ± 19.2% of the total drug, whereas compliance with the schedule was 69.1% ± 27.0%. Subjects reported 96.7% ± 4.2% of the total body temperature measurements whereas the adherence to the schedule was 59.0% ± 25.0%, which remarkably decreased after major protocol amendments. In conclusion, we evaluated a blockchain‐based dynamic consent platform in real clinical trial settings. The results suggested that major changes should be avoided unless subjects' proper understanding is warranted. [ABSTRACT FROM AUTHOR]

Purpose: Lutetium-177 prostate-specific membrane antigen-617 (177Lu-PSMA-617) in end-stage metastatic castration-resistant prostate cancer (mCRPC) has reported favourable outcomes. In this study, we aimed to prospectively compare the efficacy and safety of 177Lu-PSMA-617 and docetaxel in chemotherapy-naïve mCRPC patients. Methods: This was a randomized, parallel-group, open-label, phase 2, and non-inferiority trial. Chemotherapy-naïve patients with mCRPC and high PSMA-expressing lesions on 68 Ga-PSMA-11 PET/CT were randomly assigned in 1:1 ratio to 177Lu-PSMA-617 (6.0–7.4 GBq/cycle, every 8 weeks, up to 4 cycles) or docetaxel (75 mg/m2/cycle, every 3 weeks, up to 10 cycles). The primary end-point was best prostate-specific antigen response rate (PSA-RR), defined according to Prostate Cancer Clinical Trials Working Group-3 as proportion of patients achieving ≥ 50% decline in PSA from baseline. Non-inferiority margin of − 15% was pre-specified for PSA-RR. Results: Between December 2019 and March 2021, 40 of the 45 patients assessed for eligibility underwent randomization. Fifteen of 20 patients in 177Lu-PSMA-617 arm and 20/20 patients in docetaxel arm received treatment per protocol. Of these, best PSA-RR in the 177Lu-PSMA-617 arm was 60% (9/15) versus 40% (8/20) in the docetaxel arm. The difference in the PSA-RRs between the two arms was 20% (95% confidence interval, CI: − 12–47, P = 0.25), meeting the pre-specified criterion for non-inferiority in per-protocol analysis. Further, progression-free survival rates at 6 months were 30% and 20% in the 177Lu-PSMA-617 and docetaxel arms respectively (difference 10%, 95% CI: − 18–38, P = 0.50). Overall, treatment-emergent grade ≥ 3 adverse events occurred less frequently with 177Lu-PSMA-617 than with docetaxel (6/20, 30% versus 10/20, 50%, respectively, P = 0.20). Quality-of-life outcomes improved significantly in 177Lu-PSMA-617 arm compared to docetaxel arm (P < 0.01). Conclusion: 177Lu-PSMA-617 was demonstrated to be safe and non-inferior to docetaxel in the treatment of mCRPC and could, thus, be potentially employed earlier in the disease course rather than being solely reserved for advanced end-stage disease.

Tropifexor, a non–bile acid farnesoid X receptor (FXR) agonist, has dose‐proportional pharmacokinetics and no obvious major enterohepatic circulation. This open‐label study investigated the effect of hepatic impairment (HI), as determined by Child‐Pugh grade, on tropifexor's pharmacokinetics, safety, and tolerability following a 200‐μg dose in the fasted state. Blood samples were collected through 168 hours after dosing for quantification and plasma protein‐binding determination. Total tropifexor exposure was comparable across participants with HI vs those with normal hepatic function. Tropifexor was highly protein bound (>99%) in human plasma across participants of all groups. The average unbound fractions (percentage free) were 0.14% in participants with normal hepatic function and mild HI, which increased to 0.17% and 0.24% in participants with moderate and severe HI, respectively. Similar unbound drug exposure was noted in participants with mild HI and normal hepatic function. Participants with moderate HI (N = 8) had a 1.6‐fold increase in unbound exposure (area under the plasma concentration–time curve from time 0 to infinity [AUCinf,u]) and a 1.3‐fold increase in maximal exposure (Cmax,u) vs those with normal hepatic function (geometric mean ratio: AUCinf,u, 1.64 [90%CI, 1.25‐2.16]; Cmax,u, 1.30 [90%CI, 0.96‐1.76]). Participants with severe HI (N = 8) had a 1.6‐fold increase in AUCinf,u (1.61 [90%CI, 1.04‐2.49]) and comparable Cmax,u (1.02 [90%CI, 0.60‐1.72]) compared to participants with normal hepatic function. Tropifexor was well tolerated. The relative insensitivity of tropifexor to HI offers the potential to treat patients with severe liver disease without dose adjustment. [ABSTRACT FROM AUTHOR]

Over the past 30 years there has been a surge of research on the placebo effect using a neuroscientific approach. The interesting aspects of this effort are related to the identification of several biological mechanisms of both the placebo and nocebo effects, the latter of which is defined as a negative placebo effect. Some important translational implications have emerged both in the setting of clinical trials and in routine medical practice. One of the principal contributions of neuroscience has been to draw the attention of the scientific and medical communities to the important role of psychobiological factors in therapeutic outcomes, be they drug related or not. Indeed, many biological mechanisms triggered by placebos and nocebos resemble those modulated by drugs, suggesting a possible interaction between psychological factors and drug action. Unfortunately, this new knowledge regarding placebos has the potential of being dangerously exploited by pseudoscience. [ABSTRACT FROM AUTHOR]

Capsule of alkaloids from the leaf of Alstonia scholaris (L.) R.Br. (Apocynaceae) (CALAS) is a new investigational botanical drug (No. 2011L01436) for bronchitis, post-infectious cough and asthma. To observe the clinical safety and tolerability of CALAS. Subjects were assigned to eight cohorts, and each received randomly CALAS or placebo in one of single ascending dose (SAD) of 8, 40, 120, 240, 360, 480, or in one of multiple ascending dose (MAD) of 40 or 120 mg, three times daily for 7 days. Each cohort contained two placebo subjects. Sixty-two enrolled volunteers completed the study and no serious adverse events and clinically significant changes in vital signs, electrocardiography, and upper abdominal Doppler ultrasonography were observed. The ratios of treatment-emergent adverse events (TEAEs) were reported in 11/46 (23.91%) of CALAS groups and 3/16 (18.75%) of the placebo group (p > 0.05), respectively, based on the results of SAD and MAD. All TEAEs were mild, transient, and disappeared without any intervention. The TEAEs possibly related to CALAS treatment were as followings: hiccups (4/46: 8%), dry mouth and nausea (3/46: 6%), increased sleep (2/46: 4%), abdominal distension (1/46: 2%), bilirubin elevated (1/46: 2%). CALAS is safe and well-tolerated with no unexpected or clinically relevant safety concerns up to a single dose of 360 mg and three times daily for 7 days up to 120 mg in healthy Chinese volunteers, supporting further Phase II studies.
