Researchers are evaluating BLU-5937, an oral drug, in adults with refractory chronic cough, including unexplained chronic cough, in a randomized, double-blind, placebo-controlled Phase 3 study. The main goal is to assess how BLU-5937 affects 24-hour cough frequency over 24 weeks. This study also monitors safety by tracking adverse events and changes in various health parameters during the treatment period. Participants are randomly assigned to one of three groups BLU-5937 25 mg twice daily, BLU-5937 50 mg twice daily, or a matching placebo taken twice daily. The treatment lasts for 24 weeks, and participants receive their assigned oral medication regularly throughout this time. The study uses a parallel-arm design and includes an extension in China. During the study, participants undergo assessments including cough frequency measurement, vital signs, blood tests for hormones and chemistry, hematology, and ECGs at baseline and Week 24. Researchers also evaluate cough severity and quality of life using questionnaires. Safety is closely monitored by recording adverse events, treatment discontinuations, and laboratory changes. The total participation duration is 24 weeks, with follow-up assessments at specified intervals.

Researchers are evaluating the effectiveness and safety of a new drug called GSK3862995B in adults with bronchiectasis, a chronic lung disease. This Phase 2 study also examines how the body processes the drug and checks for any immune reactions. Participants will be randomly assigned to receive one of two doses of GSK3862995B or a placebo to compare their effects on bronchiectasis. Participants will receive either Dose Level 1 or Dose Level 2 of GSK3862995B, or a matching placebo. The study uses a double-blind, randomized design, meaning neither participants nor researchers know who gets which treatment. The treatment period lasts up to 48 weeks, during which participants receive repeated doses. The study also includes assessments up to 72 weeks to monitor safety and immune responses. During the trial, participants will undergo evaluations including lung function tests, quality-of-life questionnaires, and monitoring of respiratory symptoms. Researchers will track the number of lung exacerbations, serious adverse events, laboratory tests, vital signs, and electrocardiograms to assess safety and effectiveness. Participants will be involved in regular visits and assessments throughout the treatment and follow-up periods, lasting up to about 72 weeks in total.
