Researchers are evaluating the efficacy and safety of Antiwei granules for treating the common cold, specifically the wind-cold syndrome. This is a multicenter, randomized, double-blind, placebo-controlled Phase 3 clinical trial sponsored by Tasly Pharmaceutical Group Co., Ltd. It aims to assess how well Antiwei granules work and how safe they are in adults aged 18 to 65 with recent onset of common cold symptoms. Participants will be randomly assigned to receive either Antiwei granules or a matching placebo. The treatment involves taking one sachet of granules 6 grams orally three times a day, for three days. Both groups follow the same dosing schedule, taking nine sachets total. The study compares outcomes between the Antiwei granule group and the placebo group over this short treatment period. Throughout the trial, participants will be closely monitored with assessments focusing on the cure rate after three days of treatment. Researchers will also track symptom recovery time, remission rate, disappearance of individual symptoms, traditional Chinese medicine syndrome efficacy, changes in symptom severity, occurrence of complications, emergency medication use, and overall cure of cough and cold symptoms. The total participation time includes the three-day treatment and monitoring period to evaluate treatment effects and safety.

Researchers are evaluating the safety and effectiveness of TQC2731 injection in adults with severe asthma that is not well controlled. This is a Phase III clinical trial where 660 participants with asthma are randomly assigned to receive either TQC2731 or a placebo. The study aims to see if TQC2731 can reduce asthma worsening episodes over one year compared to placebo. Participants receive either the TQC2731 injection or placebo every four weeks for up to 48 weeks through subcutaneous injection. The treatment cycles repeat monthly from the start until Week 48. The study compares these two groups to assess the impact on asthma symptoms and lung function. Throughout the trial, participants will have regular assessments including lung function tests, asthma symptom diaries, quality of life questionnaires, and blood tests for inflammation markers and immune response. Researchers track the number of asthma exacerbations during the 52 weeks of treatment and up to 64 weeks for some outcomes. Safety and immune reactions are monitored carefully. The total study duration for each participant is about one year of treatment plus follow-up.
