Brief Title  ICMJE A Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of PF-06842874 in Healthy Participants
Official Title  ICMJE A PHASE 1, RANDOMIZED, DOUBLE-BLIND, SPONSOR-OPEN, PLACEBO-CONTROLLED, FIRST-IN-HUMAN STUDY TO EVALUATE THE SAFETY, TOLERABILITY, AND PHARMACOKINETICS OF SINGLE ASCENDING ORAL DOSES OF PF-06842874 ADMINISTERED AS AN IMMEDIATE-RELEASE OR MODIFIED-RELEASE FORMULATION TO HEALTHY ADULT PARTICIPANTS AND AN OPEN-LABEL ASSESSMENT OF THE RELATIVE BIOAVAILABILITY OF A MODIFIED-RELEASE FORMULATION OF PF-06842874
Brief Summary 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.
