A Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of PF-06842874 in Healthy Participants

Completed · Phase 1 · Has a placebo group

Conditions studied: Healthy Participants

In brief

This study will be the first time PF-06842874 is administered to humans. The purpose of Part A of the study is to investigate the safety, tolerability, and pharmacokinetics of PF-06842874 following administration of single oral doses as an immediate-release or modified-release formulation to healthy adult participants. Part B of this study will evaluate the relative bioavailability of a modified-release formulation of PF-06842874 for its potential use in future clinical studies. The effect of food on PF-06842874 pharmacokinetics may also be evaluated in this study.
