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 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.
