A Single Dose Study Of PF-06291874 In Healthy Adult Subjects

A Phase 1, Randomized, Double Blind, Sponsor Open, Placebo-Controlled, Single Dose Escalating Study To Assess The Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics Of PF-06291874 After Administration Under Fasted And Fed Conditions In Healthy Adult Subjects

The primary purpose of this study is to evaluate the safety and tolerability, pharmacokinetics, and pharmacodynamics of single oral doses of PF-06291874 in healthy volunteers.

Study Overview

• Status: Terminated
• Conditions: Healthy
• Intervention / Treatment: Drug: PF-06291874 or placebo; Drug: PF-06291874 or Placebo

Detailed Description

The primary purpose of this trial is to evaluate the safety and tolerability, pharmacokinetics, and pharmacodynamics of single oral doses of PF-06291874 in healthy volunteers. The trial was terminated on Jan 9, 2012, due to undesired pharmacokinetic properties. The decision to terminate the trial was not based on any safety or efficacy concerns.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Cohort A; Each subjects in Cohort A will receive 3 single doses of PF-06291874 and 1 placebo dose in random order in Periods 1-4.	Drug: PF-06291874 or placebo; PF-06291874 will be administered as an extemporaneously prepared suspension for all doses within the initially planned range of 3 mg to 100 mg. Correspondingly, placebo doses will be administered as suspension.
Experimental: Cohort B; Each subjects in Cohort B will receive 2 single doses of PF-06291874 and 1 placebo dose in random order in Periods 1-3; in addition, 1 dose of PF-06291874 will be administered in Period 4 in the fed state.	Drug: PF-06291874 or Placebo; PF-06291874 will be administered as an extemporaneously prepared suspension for all doses within the initially planned range of 300 mg to 650 mg. Correspondingly, placebo doses will be administered as suspension.
