Researchers are evaluating the safety, tolerability, and therapeutic effects of BNT113 combined with pembrolizumab compared to pembrolizumab alone as a first-line treatment for patients with unresectable recurrent or metastatic head and neck squamous cell carcinoma HNSCC positive for human papilloma virus 16 HPV16 and expressing the protein PD-L1 with a combined positive score of 1 or higher. This is an open-label, multi-site, Phase IIIII clinical trial consisting of two parts an initial safety run-in phase and a randomized phase. In the safety run-in phase Part A, patients receive BNT113 in combination with pembrolizumab to confirm safety and tolerability at selected dose levels. The randomized phase Part B compares BNT113 combined with pembrolizumab against pembrolizumab monotherapy. Treatments are given by intravenous injection or infusion and continue for up to 24 months. An optional pre-screening phase allows tumor samples to be tested for HPV16 DNA and PD-L1 expression before the main trial screening. Participants will be closely monitored throughout the study. Assessments include safety evaluations, tumor response, and survival outcomes such as overall survival and progression-free survival. Tumor tissue samples must be provided for testing. Researchers will measure treatment-emergent adverse events, response rates, duration of response, and disease control. The study may last up to 48 months, with ongoing safety and efficacy monitoring during and after treatment.

This research aims to evaluate elafibranor, a study drug, compared to a placebo in adults with Primary Biliary Cholangitis PBC and cirrhosis, a liver disease causing bile duct damage and scarring. The trial focuses on whether elafibranor can better prevent worsening of the disease, including progression leading to liver transplant or death, and also assesses long-term safety and symptom impact such as itching and tiredness. Participants will be randomly assigned to take either an 80 mg tablet of elafibranor or a matching placebo tablet once daily, orally, with or without food. This double-blind treatment period can last up to 3.5 years for each participant, with tablets taken at approximately the same time each morning. The study is designed to compare these two groups over the long term. During the study, participants will undergo regular assessments including physical exams, vital signs, electrocardiograms, laboratory tests, and symptom questionnaires at intervals up to 3.5 years. Researchers will measure liver function tests, symptom scales, liver stiffness, and clinical outcomes related to disease progression. Safety is monitored through adverse event tracking and laboratory parameters, with follow-up extending to four weeks after the last dose. Overall participation may last up to 3.5 years.

Researchers are evaluating the efficacy and safety of two different dose regimens of pegozafermin compared to a placebo in adults with metabolic dysfunction-associated steatohepatitis MASH who have liver fibrosis stage F2 or F3. This Phase 3 study aims to better understand how pegozafermin may impact liver fibrosis and steatohepatitis in this population. Participants will receive subcutaneous injections of either one of two pegozafermin regimens or a matched placebo. These treatments are given in parallel groups, and participants are randomly assigned to one of the study groups. The study compares the effects of pegozafermin on liver fibrosis and steatohepatitis over a treatment period that includes evaluations up to 52 weeks and monitoring for disease progression up to 5 years. During the study, participants will be monitored through biopsies and blood tests to assess liver fibrosis improvement, resolution of steatohepatitis, changes in liver enzyme levels, and enhanced liver fibrosis scores. Safety and disease progression are also tracked throughout the study period. The total participation duration includes treatment and long-term observation to evaluate outcomes and any potential changes in liver health.

This research focuses on inherited retinal dystrophies caused by rare genetic variants. It is an international, multicenter observational study that includes a registry and a natural history study. The registry collects genetic and clinical data across many genes linked to retinal dystrophies, while the natural history study follows participants over time to better understand disease progression, structural and functional changes, and risk factors. This study aims to aid future clinical trials by identifying sensitive outcome measures and well-defined patient subgroups. Participants will first undergo a screening phase where their prior genetic test reports are reviewed to confirm eligibility based on specific genetic criteria. Those meeting criteria enter the registry phase, which involves annual phone follow-ups up to four years or until further enrollment into the natural history study, if their gene is selected for this phase. The natural history study includes in-person baseline and follow-up clinic visits with detailed assessments to track disease changes over time. During the study, participants undergo various visual function tests such as visual acuity, visual field sensitivity, contrast sensitivity, color vision, and retinal function measurements annually for up to four years. Structural changes in the retina are also assessed yearly using imaging techniques. Participants may be assigned to different cohorts based on age and vision status, with tailored testing schedules. The study monitors changes through standardized evaluations and collects data to characterize the natural progression of retinal dystrophies linked to rare genetic variants.
