This research aims to evaluate the long-term safety and explore the efficacy of astegolimab in adults aged 40 to 90 years with chronic obstructive pulmonary disease COPD. It focuses on participants who have completed a 52-week placebo-controlled treatment period in previous studies GB43311 or GB44332. The study is a phase 3, open-label extension to gather extended safety information on this drug in COPD patients. Participants from the parent studies who qualify will receive subcutaneous injections of astegolimab every two weeks throughout the study until it ends. This open-label extension allows all participants to receive the active drug without placebo comparison. The study continues treatment beyond the initial 52-week period to monitor long-term effects. During the study, participants will be monitored for adverse events up to 12 weeks after their last dose of astegolimab. Researchers will collect safety data to understand the incidence of any side effects. The study involves regular assessments and follow-ups to ensure participant well-being, with the total duration lasting until July 2034.

Researchers are evaluating the efficacy, safety, and tolerability of a subcutaneous drug called lunsekimig compared to placebo in adults aged 40 to 80 years who have inadequately controlled Chronic Obstructive Pulmonary Disease COPD with an eosinophilic phenotype. This Phase 2b3 study aims to better understand how lunsekimig might affect COPD symptoms and exacerbations in this specific group. Participants will be randomly assigned to one of three groups lunsekimig dose regimen A, lunsekimig dose regimen B, or a matching placebo. All treatments are given by subcutaneous injection during a 48-week intervention period. The study includes a screening period up to 4 weeks before treatment and an approximately 8-week follow-up after the intervention, for a total duration of up to 60 weeks. During the study, participants will have regular assessments including lung function tests and symptom questionnaires. Researchers will monitor the annual rate of moderate-to-severe COPD exacerbations as the primary outcome. Secondary measures include changes in lung function and quality of life scores, along with safety evaluations such as monitoring adverse events and laboratory tests. Blood samples will be collected to measure drug levels and antibody responses. Participants are observed throughout the treatment and follow-up periods to assess the effects and tolerability of lunsekimig.
