Description

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.

Official Title

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
