Brief summary

The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-07275315) in healthy participants. This study is seeking participants who: * Are healthy as determined by medical evaluation. * Are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures. * Have a body mass index (BMI) of 17.5 to 32 kilogram per meter square - a total body weight of more than 50 kilograms (110 pounds) Participants will be divided randomly into 8 different groups. All participants will receive either one PF-07275315 or a harmless treatment that has no medical effect (placebo) intravenous (IV) infusion (given directly into a vein). Participants will take part in this study for up to 541 days. During this time, eligible participants will receive single increasing amounts of PF-07275315 or placebo. Increase will only occur if the sponsor agrees that the next dose is likely to have acceptable safety and tolerability. The follow-up visit will take place 271 days after first treatment.

Detailed description

This is an first-in-human within-cohort randomized, participant- and investigator-blind, sponsor-open, placebo-controlled study of the safety, tolerability, PK, and PD following single and multiple escalating doses of PF-07275315 that will be conducted in healthy adults.
