Study Endpoints

Primary Endpoints

Phase 2 part: Change from baseline in pre-bronchodilator Forced Expiratory Volume in 1 Second (FEV1) at Week 24
Baseline to Week 24

FEV1 is the maximal volume of air exhaled in the first second of a forced expiration from a position of full inspiration. FEV1 is obtained from spirometry.

Phase 3 part: Annualized rate of moderate or severe ECOPD
Baseline to Week 52

Exacerbation of Chronic Obstructive Pulmonary Disease (ECOPD) are sudden worsening of respiratory symptoms that significantly worsen lung function and quality of life.

Frequently asked questions about PF-07275315

What is PF-07275315?

PF-07275315 is an investigational small molecule developed by Pfizer, Inc. (ticker PFE) for respiratory and inflammatory conditions. It is being studied in Phase 2 clinical trials for moderate to severe chronic obstructive pulmonary disease, moderate to severe asthma, and atopic dermatitis. It is not described as approved and remains in clinical development.

What does PF-07275315 target?

PF-07275315 targets the cytokines IL-4, IL-13, and TSLP. These cytokine targets place it in the cytokine target class, and the drug is formulated as a small molecule. Its clinical program spans respiratory and inflammatory indications, including asthma, atopic dermatitis, and moderate to severe COPD.

What is PF-07275315 used for?

PF-07275315 is being studied for moderate to severe chronic obstructive pulmonary disease, moderate to severe asthma, and atopic dermatitis. These are investigational uses in Phase 2 trials, not approved indications. The COPD and asthma studies are recruiting, while the atopic dermatitis study is active but no longer recruiting.

Who makes PF-07275315?

Pfizer, Inc. (ticker PFE) develops PF-07275315. Pfizer is running the Phase 2 program across three indications: moderate to severe COPD, moderate to severe asthma, and atopic dermatitis. The trials enroll adults, with the COPD study starting at age 35 and the asthma and atopic dermatitis studies starting at age 18.

What phase is PF-07275315 in?

PF-07275315 is in Phase 2 clinical development. All three of its listed studies are Phase 2 trials. The COPD and asthma studies are currently recruiting, and the atopic dermatitis study is active but not recruiting. The program has not been described as FDA approved and remains investigational.

What clinical trials is PF-07275315 in?

PF-07275315 is in three Phase 2 trials: NCT07363694 in moderate to severe COPD, NCT06977581 in moderate to severe asthma, and NCT05995964 in moderate to severe atopic dermatitis. All are randomized, double-blind, and placebo-controlled. The COPD trial is the largest, with planned enrollment of 1,156 participants across 18 countries.

Is PF-07275315 the same as PF-07275315 dose 1?

PF-07275315 dose 1 refers to a dose level of PF-07275315, the investigational small molecule from Pfizer (ticker PFE). Searches for PF-07275315 dose 1 point to the same drug candidate being studied in Phase 2 trials for moderate to severe COPD, moderate to severe asthma, and atopic dermatitis.
