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 evaluating whether the drug zilebesiran can reduce the risk of major cardiovascular events such as cardiovascular death, nonfatal heart attacks, strokes, or heart failure in adults who have hypertension that is not well controlled and who either have established cardiovascular disease or are at high risk for it. This Phase 3 global study is designed to continue until enough cardiovascular events have occurred to assess the treatment's effect. Participants will be randomly assigned to receive either zilebesiran or a placebo, both given as injections under the skin (subcutaneous administration). All participants will continue with their standard care, which includes treatment with at least two antihypertensive medications, one of which must be a diuretic such as a thiazide or loop diuretic. The study is double-blind, so neither participants nor researchers know who is receiving the active drug or placebo. During the study, participants will be closely monitored for cardiovascular events including heart attacks, strokes, heart failure hospitalizations, and cardiovascular deaths over approximately five years. Researchers will collect data on these events to determine the time until the first occurrence of any of these outcomes. Safety assessments and standard clinical evaluations will also be performed throughout the study period to ensure participant well-being.
