Researchers are evaluating whether the medicine tenecteplase helps adults recover from an acute ischemic stroke when given more than 4.5 hours after they were last seen well. This study focuses on people who had a stroke caused by a clot blocking blood flow in the brain and who have imaging showing brain tissue that can still be saved. Participants should not be planning to receive a procedure to remove the clot and must have a pre-stroke disability level of 0 or 1 on the modified Rankin Scale. Participants are randomly placed into two groups. One group receives a single injection of tenecteplase into a vein, while the other group receives standard medical care. The study includes adults aged 18 and over who had an acute stroke or woke up with stroke symptoms more than 4.5 hours ago. Imaging with MRI or CT is used to confirm eligibility. The study lasts about three months, starting with a hospital stay of about one week. During the study, participants have seven clinical examinations or visits to monitor their recovery and health. The last two visits may be done from home to allow remote assessments. Researchers use the modified Rankin Scale to measure disability or dependence in daily activities at 90 days after treatment. They also monitor for any side effects or health changes to compare the effects of tenecteplase against standard care.

Researchers are evaluating whether the medicine vicadrostat, combined with empagliflozin, helps adults with chronic heart failure (HF) who have a weakened heart pumping function, specifically a left ventricular ejection fraction (LVEF) below 40%. Eligible participants must have been diagnosed with chronic HF at least 3 months before joining. The study is a Phase III trial designed to compare the effects of vicadrostat plus empagliflozin against placebo plus empagliflozin in people with symptomatic chronic HF classified as New York Heart Association classes II to IV. Participants are randomly assigned to one of two groups. One group takes tablets containing vicadrostat and empagliflozin, while the other group takes placebo tablets that look like vicadrostat along with empagliflozin. Tablets are taken once daily for a period ranging from about 6 months up to about 3.5 years. Participants continue their usual heart failure treatments during the study. The study is double-blind, meaning neither the participants nor the study staff know who is receiving which treatment. During the study, participants regularly visit the study site or may have phone contacts for follow-up. They answer questions about their health and well-being. Doctors monitor and record any worsening of heart failure symptoms, hospital visits due to heart failure, or deaths. They also check participants' overall health and note any side effects. The main outcome measured is the time until a participant experiences cardiovascular death, hospitalization for heart failure, or an urgent heart failure visit, over up to 43 months of follow-up.

This study is open to adults aged 18 or above legal age with heart failure. People can join the study if they have heart failure symptoms and a left ventricular ejection fraction (LVEF) of 40% or more. The purpose of this study is to find out whether vicadrostat (BI 690517) in combination with empagliflozin helps people with heart failure. Participants are put into 2 groups by chance. Every participant has an equal chance of being in each group. The groups are: * Vicadrostat/empagliflozin group: participants take vicadrostat/empagliflozin as tablets once a day. * Placebo/empagliflozin group: participants take placebo/empagliflozin as tablets once a day. Participants can stay in the study as long as they benefit from treatment and can tolerate it. During this time, they visit their doctors regularly. The doctors regularly check participants' health and take note of any unwanted effects. The study staff may also contact the participants by phone. Participants also regularly answer questions about their well-being. The study does not have a fixed duration. It continues until there is enough data to see if the treatment is working.

Researchers are establishing a standardized clinical information database for liver cancer patients through a collaborative effort led by the Department of Hepatobiliary Surgery at the First Affiliated Hospital of the University of Science and Technology of China (USTC). This database aims to support high-quality real-world clinical studies and research on hepatocellular carcinoma and related liver cancers. Participants may receive routine treatments such as surgical operations including resection, ablation, transarterial chemoembolization (TACE), and hepatic arterial infusion chemotherapy (HAIC). They might also be treated with various anti-tumor drugs including immunologic, targeted, and chemotherapy medications. Treatments and clinical data are collected to enrich the database for future research. During the study, participants will provide blood samples and postoperative pathology residual samples and will be followed over time to monitor their health and treatment outcomes. The primary outcome measured is overall survival over 10 years. Participants must be willing to comply with follow-up visits and provide informed consent, ensuring comprehensive data collection for long-term analysis.

Researchers are evaluating the effects and safety of the drug TNTL in adults with non-proliferative diabetic retinopathy, a condition affecting the eyes related to diabetes. This Phase III clinical trial compares TNTL to a placebo to determine if TNTL can improve visual clarity and reduce the severity of retinopathy. The study also aims to identify any medical issues participants may experience while taking TNTL. Participants will take either TNTL or a placebo orally, four tablets three times a day after meals, for 24 weeks (6 months). They will visit the clinic every 4 weeks for checkups and testing during the treatment period. The study includes two groups: one receiving TNTL and the other receiving a placebo designed to look like TNTL. During the study, participants will keep a diary of symptoms and changes. Researchers will measure the change in best corrected visual acuity (BCVA) from the start of the study to the end of treatment at 24 weeks. Regular assessments and safety monitoring will be conducted throughout the 6-month treatment period to evaluate both effectiveness and safety.

Researchers are investigating whether the medicine vicadrostat, when taken together with empagliflozin, can lower the risk of heart-related problems in adults who have type 2 diabetes, high blood pressure, and cardiovascular disease but no history of heart failure. This study is a Phase III trial that compares the effects of vicadrostat plus empagliflozin to a placebo plus empagliflozin in people with these conditions. Participants are randomly assigned to one of two groups: one group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets that look like vicadrostat along with empagliflozin. All participants take one tablet daily for a period ranging from two and a half years up to four years and three months. Throughout the study, participants continue their usual medications for diabetes, high blood pressure, and cardiovascular disease. During up to 51 months of participation, participants visit the study site regularly where doctors collect health information and blood samples. Researchers track when participants experience cardiovascular events such as heart-related deaths or heart failure events. The study also monitors participants’ overall health and any side effects they may experience to assess the safety and effects of the treatments.

Researchers are evaluating the safety and effectiveness of two low-dose atropine sulfate eye drops (0.01% and 0.02%) in delaying the progression of myopia in children and adolescents aged 6 to 12 years. This Phase III, randomized, double-blind, placebo-controlled study aims to compare these treatments to placebo over a 96-week period, with additional exploratory objectives to assess longer-term efficacy and possible rebound effects after stopping treatment. Participants will be randomly assigned to receive either 0.01% atropine sulfate eye drops, 0.02% atropine sulfate eye drops, or placebo eye drops. Each treatment involves applying one drop in each eye every night before sleep, followed by gently pressing the tear duct area on both sides for about one minute. The study will monitor participants throughout the treatment period and may include extended observation for up to 144 weeks to explore longer-term outcomes. During the study, children will attend regular visits for assessments including measurement of eye refraction under cycloplegia to evaluate changes in myopia. Researchers will also monitor safety and any side effects throughout the treatment. The primary outcome is the change from baseline in equivalent spherical refraction at the Week 96 visit. Participants will be required to comply with study visits and procedures, including telephone follow-ups, to support data collection and safety monitoring over the course of the trial.
