A Study to Learn About the Study Medicine Called PF-07868489 in Healthy Adult People and in People With Pulmonary Arterial Hypertension

Phase 1
Recruiting
Conditions
Pulmonary Arterial Hypertension
Interventions
Drug: Placebo for PF-07868489
Registration Number
NCT06137742
Lead Sponsor
Pfizer
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.
