Researchers are evaluating the effects and safety of AZD6793 tablets in adults aged 40 years and older who have moderate to very severe chronic obstructive pulmonary disease (COPD). This is a Phase IIb, multicenter, randomized, double-blind, placebo-controlled study involving approximately 1160 participants at around 400 sites worldwide. The study aims to compare three different doses of AZD6793 against placebo tablets over 24 weeks to assess how well the treatment works and its safety profile in this population. Participants will be randomly assigned to one of four groups receiving either one of three doses of AZD6793 or a placebo in equal proportions. The treatment involves oral administration of AZD6793 tablets or placebo tablets daily for 24 weeks. The study is designed with parallel groups and includes careful dose-ranging to evaluate different levels of the investigational drug. During the study, participants will be monitored for the annualized rate of moderate or severe COPD exacerbations from baseline up to 24 weeks. Assessments include lung function tests such as pre- and post-bronchodilator FEV1/FVC ratios, symptom questionnaires like the COPD Assessment Test (CAT), and documentation of COPD exacerbation history. Safety will be continually evaluated through clinical assessments and laboratory tests throughout the treatment period.

Researchers are conducting a Phase 3, multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety and effectiveness of tezepelumab in adults aged 40 to 80 years with moderate to very severe chronic obstructive pulmonary disease (COPD). Participants must have experienced at least two moderate or one severe COPD exacerbations in the year before joining and be receiving inhaled maintenance therapy. The study focuses on adults who continue to experience symptoms despite current treatments and aims to assess the impact of tezepelumab on COPD exacerbations. Participants will be randomly assigned to receive monthly subcutaneous injections of either one of two doses of tezepelumab or a placebo. Treatment will last for a minimum of 52 weeks and may extend up to 76 weeks. After the treatment period, there will be a 12-week safety follow-up phase to monitor participants after stopping the study drug. The study compares tezepelumab to placebo to determine its efficacy and safety over this extended period. During the study, participants will undergo regular assessments to monitor their COPD status and any exacerbations. The main outcome measured is the annual rate of moderate or severe COPD exacerbations from the start of treatment through up to 76 weeks. Safety and tolerability will also be closely monitored throughout the treatment and follow-up periods. This long-term involvement ensures comprehensive data on how tezepelumab affects COPD progression and exacerbation frequency.
