Brief Summary
The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-07275315) for the potential treatment of moderate-to-severe asthma. Asthma is a condition that makes it challenging to breathe, which negatively impacts the quality of life and functioning of people who are affected. This study is seeking participants who:
- Are 18 to 70 years old
- Have had moderate-to-severe asthma for at least 12 months that is not well controlled
- Have been taking their regular maintenance treatment(s) for asthma over the last 12 months All participants will receive PF-07275315 or a placebo. A placebo does not have any medicine in it but looks just like the medicine being studied. PF-07275315 or placebo will be given as multiple shots in the clinic over the course of 12 weeks. We will compare the experiences of people receiving PF-07275315 to those of the people who do not. This will help us determine if PF-07275315 is safe and effective. Participants will be involved in this study for about 7.5 months. During this time, they will have 9 visits at the study clinic.

Outcome Measures
Primary Outcomes (5)
Change from baseline in pre-bronchodilator Forced Expiratory Volume in 1 Second (FEV1) at Week 12
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.

- Must have experienced at least 1 asthma exacerbation requiring treatment with systemic steroids (oral or parenteral) for 3 days or more within 12 months of the screening visit.
- At least 2 of the 3 pre-bronchodilator FEV1 values collected in the run-in period and the mean of the of pre-bronchodilator FEV1 values collected in the run-in period are ≥30% to \<80% of predicted normal values.
- Positive bronchodilator responsiveness as evidenced by increase in FEV1 of at least 12% and 200 mL for spirometry conducted during screening period.
- Maintenance (controller) treatment that minimally includes a medium to high dose ICS - LABA combination consistent with GINA Step 4/5 (either Track 1 or Track 2) for 12 months prior to the screening visit and at a stable dose for at least 3 months prior to the screening visit.

- Body mass index between 18 40 kg/m2 at screening.
You may not qualify if:
- Medical Conditions:
- Any medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
- Evidence of lung disease(s) other than asthma, either clinical evidence, spirometry, or imaging (Chest X-ray, CT, MRI) within 12 months of the screening visit, as per local standard of care, including but not limited to: Chronic obstructive pulmonary disease, Other emphysematous lung disease such as alpha-1 antitrypsin disease, Cystic fibrosis, Emphysema, Idiopathic pulmonary fibrosis, Churg-Strauss syndrome, Allergic bronchopulmonary aspergillosis, Sarcoidosis

- Any infection judged to be an opportunistic infection or clinically significant by the investigator, within 6 months prior to Day 1.
- Prior/Concomitant Therapy:
- Prior or current use of any prohibited concomitant medication(s) or unwillingness or inability to use a required concomitant medication(s).
- Prior or concurrent treatment with either approved or experimental biologic treatment (such as inhibitors of IL-4, IL-13, IL-33/ST2, IL-4Rα, TSLP, IL-5, OX40/OX40L or IgE) or targeted synthetic drugs (such as JAK inhibitors) for the treatment of asthma or other type 2 inflammatory diseases, including but not limited to: AD, EoE, CRS.
