Researchers are evaluating the efficacy and safety of verekitug (UPB-101) in adults with moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD), a long-term inflammatory lung condition. This global, multicenter Phase 2b study aims to understand how well verekitug works compared to a placebo, alongside participants' usual COPD medications. Participants must have a confirmed COPD diagnosis and meet specific lung function and symptom criteria to join the study. Participants will be randomly assigned to receive one of two doses of verekitug or a matching placebo, in addition to their regular COPD background treatments. The study includes a screening period of about 4 weeks, followed by treatment lasting between 60 and 108 weeks. After treatment, there is a 16-week follow-up period to monitor participants after their last dose. Throughout the study, participants will undergo various assessments including lung function tests and symptom evaluations. Researchers will track the annual rate of moderate or severe COPD flare-ups from the start of treatment through week 108. Safety and tolerability will be closely monitored during the treatment and follow-up periods to ensure participants' well-being over the course of the trial.

Researchers are evaluating the safety and effectiveness of astegolimab compared to a placebo in adults aged 40 to 80 years who have chronic obstructive pulmonary disease (COPD). The study focuses on participants who are former or current smokers with a history of frequent COPD flare-ups. This phase III trial aims to determine how well astegolimab reduces moderate and severe COPD exacerbations over one year. Participants will be randomly assigned to receive either subcutaneous astegolimab every two or four weeks or a placebo every two weeks. All participants will continue their optimized COPD maintenance treatments, which may include combinations of inhaled corticosteroids, long-acting beta-agonists, and long-acting muscarinic antagonists. Study treatments will be administered over a 52-week period. Throughout the study, researchers will monitor the annual rate of moderate and severe COPD exacerbations. Participants will undergo lung function tests, chest imaging, and assessments of breathlessness and lung health. The study will also carefully track the safety of the treatments, including any infections or heart-related problems. The total participation time is 52 weeks, during which the effectiveness and safety of astegolimab will be evaluated.

This research aims to evaluate the long-term safety and explore the effectiveness of astegolimab in people with chronic obstructive pulmonary disease (COPD) who have already completed a 52-week treatment in previous studies GB43311 or GB44332. The study focuses on participants aged 40 to 90 years and is a Phase III open-label extension trial designed to continue monitoring patients after their initial treatment period. Participants will receive astegolimab as a subcutaneous injection every two weeks during this extension study. This treatment continues from the prior placebo-controlled phase, allowing researchers to observe any ongoing effects and safety concerns over a longer period. The study does not include a placebo group during this extension phase, and all participants receive the active treatment. Throughout the study, researchers will closely monitor participants for any adverse events up to 12 weeks after the last dose of astegolimab. Participants will be assessed regularly to ensure their safety and to gather data on the treatment's long-term impact. The total duration of participant involvement depends on when they completed the parent studies but involves continued monitoring during and after the treatment period.

Researchers are evaluating the safety and effectiveness of tezepelumab in children aged 5 to under 12 years who have severe uncontrolled asthma. These children must be on medium to high doses of inhaled corticosteroids along with at least one other asthma controller medication, with or without oral corticosteroids. This phase 3, multicenter, double-blind, placebo-controlled study aims to better understand how tezepelumab affects asthma control in this pediatric population. Participants will be randomly assigned in a 2:1 ratio to receive either subcutaneous injections of tezepelumab or a matching placebo for 52 weeks during the double-blind treatment period. Before this, there is a 4 to 6 week screening and run-in phase. After the treatment period, a 12-week follow-up phase occurs without treatment. Eligible participants can then join an optional open-label extension, receiving tezepelumab for an additional 104 weeks followed by another 12-week post-treatment follow-up. Throughout the study, participants will have regular assessments including lung function tests, asthma control questionnaires, and monitoring for asthma exacerbations. Researchers will measure the annualized rate of severe asthma flare-ups from the start of treatment to week 52. Safety and treatment adherence will also be closely monitored during all study phases, with total participation potentially extending over two years for those in the extension period.

Researchers are evaluating the effects of two inhalers, budesonide/albuterol metered-dose inhaler (BDA MDI) and albuterol sulfate metered-dose inhaler (AS MDI), both taken as needed, on reducing severe asthma attacks in adolescents aged 12 to under 18 years who have a clinical diagnosis of asthma and have experienced at least one severe asthma exacerbation in the past year. This is a Phase IIIb randomized, double-blind, multicenter study lasting 52 weeks with a safety follow-up period after treatment. Participants will be randomly assigned to receive either BDA MDI 160/180 micrograms (two puffs of 80/90 micrograms) or AS MDI 180 micrograms (two puffs of 90 micrograms) as needed, alongside their usual asthma maintenance therapy, for 52 weeks. The study includes a 7 to 28-day screening period before treatment and a safety follow-up visit 7 to 14 days after the end of treatment. Additionally, a pharmacokinetic sub-study involves a single dose of open-label BDA MDI administered after the safety follow-up. During the study, participants will be monitored for the annual rate of severe asthma exacerbations from randomization to week 52. Assessments include evaluating inhaler technique, peak expiratory flow measurements, and adherence to contraception methods for participants of childbearing potential. Safety will be monitored throughout the treatment and follow-up periods. The total study duration includes screening, 52 weeks of treatment, and safety follow-up.
