Researchers are evaluating the efficacy and safety of GB491 combined with Letrozole compared to placebo combined with Letrozole in treating patients with hormone receptor-positive HR and human epidermal growth factor receptor 2-negative HER2- locally advanced or metastatic breast cancer. This study focuses on patients who have not previously received systemic antitumor therapy for this condition and aims to provide new treatment insights. Participants are randomly assigned to one of two groups one receives GB491 at 150 mg orally twice daily along with Letrozole 2.5 mg orally once daily, while the other receives a placebo twice daily with the same Letrozole dose. Treatment cycles last 28 days, and the study is designed as a randomized, double-blind, placebo-controlled phase III trial. During the study, participants will be closely monitored for progression-free survival assessed by investigators using RECIST v1.1 criteria over approximately 60 months. Additional measures include overall survival, response rates, duration of response, disease control rates, clinical benefit rates, and the frequency and severity of adverse events. Regular assessments ensure safety and treatment adherence throughout the study period.

Researchers are evaluating whether survodutide can help adults with liver diseases called non-alcoholic steatohepatitis NASH or metabolic-associated steatohepatitis MASH who have cirrhosis and a body mass index BMI of 27 kgm2 or higher 25 kgm2 for Asian participants. The study compares survodutide to a placebo to see if it improves liver function and related health outcomes over time. This is a Phase III trial with participants randomly assigned to groups, and it is double-blind, meaning neither participants nor doctors know who gets the medicine or placebo. Participants receive weekly injections of survodutide or placebo under the skin and get regular counseling on diet and exercise. The study lasts up to four and a half years, with visits either in person or via video call every 2, 4, or 6 weeks for about 17 months, then every 3 months thereafter until the study ends. The study collects health data including body weight, liver imaging results, and symptom questionnaires to assess the treatment effects. During the study, doctors monitor participants health and record any side effects. Liver health is checked using imaging methods at certain visits, and participants fill out questionnaires about their symptoms. The primary outcome measures include time to serious liver-related events and overall survival. Secondary outcomes look at changes in liver fibrosis, body weight, blood sugar control, liver stiffness, and other blood markers. The study aims to provide detailed long-term information on survodutides impact on liver disease and safety.

Researchers are evaluating survodutide, a medicine given by weekly injection, in adults aged 18 and older who have obesity and a liver disease called non-alcoholic steatohepatitis NASH or metabolic associated steatohepatitis MASH with moderate or advanced liver fibrosis. The study aims to see if survodutide can improve liver function and slow disease progression. This Phase III trial compares survodutide to a placebo, with participants randomly assigned to one of the two groups, and neither participants nor doctors know who receives which treatment. Participants inject survodutide or placebo under their skin once a week, with doses gradually increasing to a target level. All participants also receive counseling to encourage diet changes and regular exercise. The study has two parts the first focuses on the effect of survodutide on liver fibrosis and MASH over 52 weeks, and the second assesses long-term safety and effectiveness up to 7 years. Participants are involved for up to 7 years, with visits to the study site or remote video calls starting every 2 weeks, then every 4 and 6 weeks, and eventually alternating every 3 months. During visits, doctors monitor health, weight, and digestive effects, perform liver imaging, and collect liver tissue samples at select times. Participants complete questionnaires about symptoms and quality of life. Researchers measure changes in liver disease markers, body weight, blood tests, and monitor safety and serious outcomes like progression to cirrhosis or liver-related events.

Researchers are studying whether combining phacoemulsification cataract surgery with gonioscopy-assisted trabeculotomy as an initial treatment can reduce the need for long-term glaucoma eye drops in adults with primary open-angle glaucoma and cataract. This trial also aims to assess if this early surgical approach improves the health of the eye surface and quality of life related to vision and anxiety compared to cataract surgery followed by standard glaucoma medications. The study compares these two treatment strategies in patients who have not previously been treated for glaucoma. Participants will be randomly assigned to one of two groups. One group will have cataract surgery combined with about 120 degrees of ab interno gonioscopy-assisted trabeculotomy using a non-device-dependent cutting tool during the same surgery. The other group will have cataract surgery followed by guideline-based topical eye pressure-lowering medications such as prostaglandin analogues and others as needed. Follow-up visits are scheduled over 24 months to monitor outcomes. During the study, participants will attend visits at specific times including Day 1, Day 7, Month 1, Month 3, Month 6, Month 9, Month 12, Month 18, and Month 24. They will undergo eye pressure checks, vision tests, OCT scans, anterior segment OCT, visual field tests, ocular surface examinations, and safety evaluations. They will also complete questionnaires about quality of life and anxiety, and provide tear samples for biomarker testing. Researchers will measure changes in eye pressure, success rates, medication use, vision quality, retinal nerve and ganglion cell layer thickness, ocular surface health, adverse events, and economic indicators.
