BACKGROUND: Endothelin receptor antagonists (ERAs) are associated with liver injury. We used data from previous oncology clinical trials to determine the liver safety profile of zibotentan, which is currently in clinical development (in combination with dapagliflozin) for chronic kidney disease and cirrhosis. RESEARCH DESIGN AND METHODS: Six global, double-blinded, phase 2b and 3 clinical trials from the zibotentan oncology development program were pooled to analyze liver safety...

INTRODUCTION: Antipsychotics are the foundation of pharmacologic treatment for schizophrenia. There are many oral antipsychotics available and given that these medications are generally considered comparably efficacious when titrated to an adequate dose, their varied tolerability and safety profiles become critically important for medication selection. AREAS COVERED: This paper reviews tolerability and safety considerations for first-line second-generation oral antipsychotics currently approved for the treatment of schizophrenia in the United States...

BACKGROUND: Shorter regimens for drug-resistant tuberculosis (DR-TB) have non-inferior efficacy compared with longer regimens, but QT prolongation is a concern. T-wave morphology abnormalities may be a predictor of QT prolongation. RESEARCH DESIGN AND METHODS: STREAM Stage 1 was a randomized controlled trial in rifampicin-resistant TB, comparing short and long regimens. All participants had regular ECGs. QT/QTcF prolongation (≥500 ms or increase in ≥60 ms from baseline) was more common on the short regimen which contained high-dose moxifloxacin and clofazimine...

INTRODUCTION: The evaluation of the potential carcinogenicity is a key consideration in the risk assessment of chemicals. Predictive toxicology is currently switching toward non-animal approaches that rely on the mechanistic understanding of toxicity. AREAS COVERED: Adverse outcome pathways (AOPs) present toxicological processes, including chemical-induced carcinogenicity, in a visual and comprehensive manner, which serve as the conceptual backbone for the development of non-animal approaches eligible for hazard identification...

BACKGROUND: The safety information of brolucizumab primarily comes from clinical trials experience. This study aimed to explore the ocular and systemic adverse events (AEs) associated with brolucizumab among real-world patients through data mining the FDA Adverse Event Reporting System (FAERS) database. METHODS: AE reports submitted to the FAERS database between October 2019 and March 2023 were extracted. The reporting odd ratio was used to evaluate AE signals associated with brolucizumab...

BACKGROUND: The study aimed to evaluate the agreement of prescribed drug dosages with renal dosing recommendations and describe adverse drug events (ADEs) contributing to hospital admissions of patients with chronic kidney disease (CKD). METHODS: This cross-sectional study focused on CKD patients admitted to University Hospital Hradec Králové, with an estimated glomerular filtration rate below 60 ml/min. The necessity for renal dosage adjustments was determined using the Summary of Product Characteristics (SmPC)...

Anticancer drug-induced interstitial lung disease (DIILD) has received increasing clinical attention, and the quality of relevant guidance documents has become critical. Our purpose was to assess the quality of documents for anticancer DIILD and summarize the recommendations. Clinical practice guidelines (CPGs) and consensus statements with recommendations for the evaluation, treatment, and monitoring of anticancer DIILD were searched in electronic databases, websites of guideline organizations, and professional societies...

BACKGROUND: Hepatic cancer is a common cancer in clinical practice. Current drug therapies for this condition include targeted therapy, chemotherapy, and immunotherapy. Tumor lysis syndrome (TLS) is the most serious complication of oncology treatment. According to the literature, several cases reported TLS occurred with targeted therapies for hepatic cancer. METHODS: Reporting odds ratio and information component were used to measure the disproportionate signals for TLS associated with targeted therapies, using data from the FDA's Adverse Event Reporting System (FAERS)...

This study investigated the patterns of hematological adverse events related to daptomycin (DAP), tigecycline (TIG), vancomycin (VAN) and linezolid (LIN) in the FDA Adverse Event Reporting System (FAERS). Adverse event associations were analyzed through calculating reporting odds ratio (ROR), proportional reporting ratio (PRR), multiple gamma Poisson shrinkage (MGPS), and Bayesian confidence propagation neural network (BCPNN). A comprehensive descriptive analysis was also conducted considering factors such as age, gender, daily dose, cumulative dose, and time to onset...

OBJECTIVES: Through the use of FDA adverse event reporting system (FAERS) dataset, this study analyzes the pattern of time-to-event (TTE) for drugs and adverse events, and suggest ways to identify candidate late-onset events for monitoring. METHODS: The duration between administration date of the drug and the onset of adverse events was explored with using FAERS data from 2012-2021. The fold change of proportional reporting ratios or reporting odds ratios were calculated to identify enriched events in the later period and to suggest the late-onset events for further monitoring...

INTRODUCTION: Bevacizumab is widely used in ovarian cancer due to its ability to extend survival. The addition of bevacizumab to chemotherapy may increase the toxicities that affect quality of life (QOL). To investigate the impact of bevacizumab on QOL during the increased survival, we conducted a meta-analysis of randomized controlled trial (RCT). METHODS: We systematically searched PubMed, Embase, Cochrane Library, Web of Science and ClinicalTrials.gov. for RCTs comparing the QOL of bevacizumab plus chemotherapy (BEV-CT) versus chemotherapy (CT) in ovarian cancer...

INTRODUCTION: Vaccine pharmacovigilance is an essential component of vaccine safety programs. Vaccine pharmacovigilance refers to detecting uncommon adverse events following immunization (AEFI), determining whether they are due to the vaccine or are only a coincidence, and, for those AEFI considered related to vaccination, characterizing them further. When AEFI are due to vaccination, it is important to characterize the attributable risk and ascertain the biological mechanism causing the adverse reaction to inform efforts to prevent or mitigate the risk...
