Researchers are evaluating the safety and effectiveness of tezepelumab in adults aged 40 to 80 years with moderate to very severe chronic obstructive pulmonary disease (COPD). These participants must have a history of COPD for at least one year and have experienced multiple COPD exacerbations despite using inhaled maintenance therapy. This Phase 3, multicenter, randomized, double-blind, placebo-controlled study focuses on those who have had at least two moderate or one severe exacerbation in the prior year while on inhaled triple or dual therapy. Participants will 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 up to 76 weeks. After the treatment period, there will be a 12-week off-treatment safety follow-up to monitor any lasting effects or safety concerns. During the study, researchers will assess the participants' lung function and monitor the annual rate of moderate or severe COPD exacerbations. Participants will undergo screening to confirm eligibility based on lung function tests, eosinophil counts, and symptom scores. Safety will be closely monitored throughout the treatment and follow-up periods to evaluate adverse effects and overall participant health.

Researchers are evaluating the safety and effects of a study medicine called PF-07275315 for treating adults with moderate-to-severe asthma that is not well controlled. This condition makes breathing difficult and affects quality of life. The study is a Phase 2, randomized, double-blind, placebo-controlled trial aiming to determine if PF-07275315 is safe and effective for this group. Participants will receive either PF-07275315 or a placebo through multiple subcutaneous injections administered in the clinic over 12 weeks. The study compares these two groups to assess treatment responses. The trial includes a total of 9 clinic visits and lasts about 7.5 months for each participant. During the study, participants will undergo various assessments including lung function tests to measure forced expiratory volume in 1 second (FEV1), safety monitoring through adverse event tracking, laboratory tests, vital sign checks, and electrocardiograms. These evaluations occur from baseline through 24 weeks to observe changes and treatment tolerability.

This research aims to evaluate the effectiveness and safety of a fixed-dose combination of fluticasone propionate (Fp) and albuterol sulfate (ABS) delivered via an integrated electronic module multidose dry powder inhaler (eMDPI) compared to ABS alone in reducing severe clinical asthma exacerbations in patients with asthma. The study also assesses the efficacy of a low dose of Fp/ABS versus ABS and examines the impact on systemic corticosteroid exposure. This is a phase 3 randomized, double-blind, active-controlled trial involving patients diagnosed with asthma for at least one year. Participants will receive either a high dose or low dose of Fp/ABS or ABS alone through oral inhalation powder during a double-blind treatment period lasting a minimum of 24 weeks. The study includes a 2-week screening phase, a 2 to 4-week run-in period, and the treatment phase. Because this is an event-driven study, the total duration for individual participants may extend up to approximately 42 months depending on enrollment timing and study completion. During the study, participants will be closely monitored for time to first severe clinical asthma exacerbation while using the inhaler device. Safety and tolerability will be evaluated throughout the study. Researchers will also track systemic corticosteroid use and overall asthma control. The minimum participation time is 28 weeks, including screening and run-in, with extended monitoring possible based on study events and criteria.
