A Study to Learn About the Study Medicine Called PF-07868489 in Healthy Adult People and in People With Pulmonary Arterial Hypertension
A PHASE 1 / 2, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED STUDY TO EVALUATE THE SAFETY, TOLERABILITY, PHARMACOKINETICS, AND PHARMACODYNAMICS OF SINGLE ESCALATING DOSES OF PF-07868489 IN HEALTHY ADULT PARTICIPANTS AND, ADDITIONALLY, CLINICAL ACTIVITY OF REPEAT DOSES IN PARTICIPANTS WITH PULMONARY ARTERIAL HYPERTENSION

Brief Summary
The purpose of the study is to learn how the study medicine called PF-07868489 is tolerated and acts in healthy adult people and people with pulmonary arterial hypertension (PAH). Part A: An investigator- and participant-blind, sponsor-open, placebo-controlled, single ascending dose study to assess the safety, tolerability, and pharmacokinetics (PK) of PF-07868489 in healthy adult participants. Part B: A 24-week, randomized, double blind, placebo-controlled study to assess the safety, tolerability, PK, and pharmacodynamics (PD) of PF-07868489 in adult participants with PAH.
