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.

Researchers are conducting a phase IIb, double-blind, placebo-controlled study to evaluate the efficacy and safety of tozorakimab in adults with uncontrolled asthma who are already receiving medium-to-high doses of inhaled corticosteroids. This study aims to find the appropriate dose range of tozorakimab for this population, focusing on those with documented asthma for at least 12 months and evidence of uncontrolled symptoms. Participants will receive either tozorakimab or a placebo, both administered subcutaneously. The study compares different doses of tozorakimab against placebo, while all participants continue their current medium or high dose inhaled corticosteroids combined with long-acting beta-agonists (LABA). The treatment period and dosing schedule are designed to assess the drug's impact on asthma control and exacerbations. During the study, participants will be closely monitored through asthma daily diaries, lung function tests including pre-bronchodilator FEV1 measurements, and assessments of asthma control using the ACQ-6 score. Researchers will track the annualized rate of severe asthma exacerbations over 26 to 52 weeks. Safety and adherence will be evaluated, and women of childbearing potential will have pregnancy testing and must use contraception as per local regulations. Overall participation will involve regular visits to assess health status and response to treatment.
