Researchers are evaluating 9MW1911 in adults aged 40 to 75 who have been diagnosed with Chronic Obstructive Pulmonary Disease COPD for at least one year. This Phase II clinical trial is designed to assess how well 9MW1911 works and how safe it is for treating COPD. The study compares two different doses of 9MW1911 given intravenously with a placebo, and aims to better understand treatment effects on COPD flare-ups and lung function. Participants receive intravenous infusions of either 9MW1911 in one of two dose levels or a placebo every 28 days. Each treatment group includes 120 patients, all receiving stable standard care for COPD. The study lasts for 52 weeks of treatment, followed by safety and immune response monitoring up to 60 weeks. Researchers measure lung function, COPD exacerbations, quality of life, and other health markers during this period. During the study, participants will have regular visits for lung function tests, questionnaires about COPD symptoms and quality of life, blood tests, and safety assessments. These assessments occur at multiple time points, such as weeks 0, 4, 8, 12, 24, 36, and 52. The main outcome is the rate of moderate to severe COPD exacerbations over one year. Additional measures include lung function changes, time to first exacerbation, and biological markers. Safety and tolerability are followed for up to 60 weeks to ensure participant well-being throughout the trial.

Researchers are studying the use of Tenecteplase TNK combined with Butylphthalide NBP in patients who have experienced mild disabling acute ischemic stroke AIS. This large, randomized, double-blind trial compares the effects of TNK plus NBP versus TNK alone to see if the combination improves neurological function and recovery. Patients eligible for the study are adults aged 18 to 80 years who have had a stroke within 4.5 hours and meet specific neurological severity criteria. Participants are randomly assigned to one of two groups. The combination group receives a single intravenous dose of TNK followed by intravenous NBP twice daily for 7 days, then oral NBP capsules three times daily until Day 14. The control group receives the same TNK dose followed by a matching placebo infusion and capsules on the same schedule. Treatments are administered during hospitalization and continue after discharge if needed. Throughout the 90-day study period, participants undergo assessments including stroke severity scores, functional recovery measured by the Modified Rankin Scale, quality of life surveys, and imaging to evaluate brain tissue salvage. Safety monitoring tracks adverse events like bleeding or vascular complications. The main outcome is the proportion of patients achieving minimal disability by 90 days, with additional evaluations of neurological improvement and stroke recurrence.
