This study is designed to test a new medicine, PF-07275315, to help people with moderate-to-severe asthma, a lung condition that makes breathing difficult. The study will last about 7.5 months, and participants will visit the clinic 9 times. During the study, participants will receive either the study medicine or a placebo, which is a fake treatment that looks like the real one but has no active ingredients.

Key Points:

• Study lasts about 7.5 months with 9 clinic visits.
• Participants receive shots either of the study medicine or a placebo.
• The study aims to see if the new medicine is safe and works well.

People aged 18-70 with asthma that's not well-controlled can join. However, they shouldn't have other lung diseases or recent severe infections. Participants should have been on regular asthma treatment for the past year. This study helps researchers understand if PF-07275315 is a safe and effective treatment choice for people with asthma.
