Researchers are evaluating how well brenipatide LY3537031 is tolerated, its side effects, and its safety and effectiveness in adults with Irritable Bowel Syndrome-Constipation IBS-C. This Phase 2 study compares brenipatide given under the skin with a placebo to better understand its impact on IBS-C symptoms. The trial is sponsored by Eli Lilly and Company and lasts about 35 weeks. Participants will receive either brenipatide or a placebo, both administered subcutaneously. The study uses a randomized, double-blind, placebo-controlled design with parallel groups. Treatment effects will be measured primarily between weeks 9 and 16, focusing on the weekly composite clinical response. Secondary outcomes include abdominal pain and bowel movement responses during the same period. During the study, participants will be monitored for safety and symptom changes. They will record abdominal pain scores daily and bowel habits using a stool form scale. Researchers will review these data along with other health assessments to evaluate the study drugs effects. The total participation duration is approximately 35 weeks, including screening, treatment, and follow-up periods.

Researchers are evaluating the safety, side effects, and effectiveness of brenipatide LY3537031 in adults with Irritable Bowel Syndrome-Diarrhea IBS-D. The study compares brenipatide administered under the skin with a placebo to understand its impact on this condition. This Phase 2 clinical trial involves participants aged 18 to 75 years. Participants will receive either the study drug brenipatide or a placebo through subcutaneous injections. The study follows a randomized, double-blind design where neither participants nor researchers know which treatment is given. Treatment and placebo administrations occur during the trial, which lasts approximately 35 weeks. During the study, participants will be monitored for how well they tolerate the drug and any side effects. Researchers will collect daily data on abdominal pain and stool consistency using an eDiary, focusing on responses between weeks 9 and 24. The primary measure is the percentage of participants achieving a daily composite response for at least half the days between weeks 9 and 16. Safety and efficacy outcomes are tracked throughout the trial period.

This research aims to develop and evaluate a stepwise screening approach for early detection of Alzheimers disease AD in community populations aged 50 and above. The study addresses the growing global burden of AD, which accounts for 60-80% of dementia cases worldwide, with a focus on scalable, accessible methods suitable for low- and middle-income settings. The study integrates digital cognitive assessments and blood-based biomarkers to improve early diagnosis during the prolonged preclinical phase of the disease. The screening process involves two main steps. The first step uses digital tools including the SCD-9 questionnaire to capture subjective cognitive complaints, a digital cognitive test PCAT assessing memory and symbol matching, and a predictive model for future dementia risk. The second step confirms AD pathology through blood-based biomarkers, comparing multiple candidates such as p-tau217, p-tau181, and A240 measured via assay platforms like Simoa and CLEIA. Amyloid PET scans serve as the gold standard for AD pathology confirmation. Participants will be community residents aged 50 years or older, without prior cognitive impairment or anti-dementia drug use, and able to communicate in Chinese. Researchers will collect and analyze data on screening sensitivity and specificity, program completion, time to completion, community feasibility, compliance, and cost-effectiveness. The study spans multiple centers nationwide and involves clinical dementia rating assessments and biomarker testing, with the goal of creating a model applicable to primary healthcare systems in developing countries.

Researchers are studying the safety and effectiveness of early use of tirofiban in patients who have acute ischemic stroke and are treated with tenecteplase. This study is exploring whether adding tirofiban soon after tenecteplase can reduce the risk of blood clot re-blockage in the brain, which happens in some patients after initial treatment. The study is a phase 3 trial aiming to improve stroke outcomes by preventing this reocclusion. Participants first receive tenecteplase intravenously for stroke treatment. Those who meet the study criteria are then randomly assigned to receive either tirofiban or a placebo. Tirofiban or placebo is given intravenously starting as soon as possible after randomization, initially as a higher dose for 30 minutes, followed by a continuous lower dose infusion for nearly 48 hours. After 24 hours, patients receive aspirin andor clopidogrel or their placebos, then after 44 hours, antiplatelet therapy with aspirin andor clopidogrel continues until the 90-day follow-up. During the study, participants undergo assessments including neurological exams and monitoring for bleeding or other adverse events. The main outcome measured is excellent functional recovery 90 days after randomization. Other outcomes include disability levels, neurological improvement, quality of life, bleeding events, and mortality. Safety and serious adverse events are tracked through the 90-day period to evaluate treatment effects and risks.

Researchers are evaluating normobaric hyperoxia NBO as a treatment for patients who have experienced an acute ischemic stroke and are transferred for endovascular thrombectomy EVT. The study aims to assess the effectiveness and safety of NBO in improving functional outcomes at 3 months after stroke. Stroke is a leading cause of death and disability, and although reperfusion treatments like thrombectomy improve blood flow, less than half of patients achieve favorable recovery. NBO is thought to protect the brain by rescuing hypoxic tissue and reducing damage processes, with advantages such as low cost and easy use. Participants will be randomly assigned to receive either NBO, which involves inhaling 100% oxygen alongside the best medical care, or best medical care alone. The study compares these two groups to see if NBO provides additional benefits. The treatment is given during the acute phase before or during transfer for EVT. The study includes a single-blind design and follows patients for outcomes over time. During the study, participants will have their disability level measured using the modified Rankin Scale at 90 days and one year after randomization. Other assessments include neurological function scores, imaging scans, infarct volume changes, and quality of life questionnaires at various time points. Safety and recovery progress are closely monitored throughout, with follow-up visits to track long-term effects. The total participation duration includes initial treatment and follow-up through one year.
