A Phase 1 Multiple-Dose Escalation and Single Dose (Tablet) Study of PF-04171327 in Healthy Volunteers

This study has been completed.
Information provided by:
Pfizer Identifier:
First received: December 19, 2008
Last updated: August 11, 2009
Last verified: August 2009
The purpose of this study is to determine the safety, tolerability, pharmacokinetics and pharmacodynamics (how the drug effects certain target sites of activity in the body) of escalating doses of oral PF-04171327 in healthy volunteers for 14 days (Part 1). Part 2 will evaluate the pharmacokinetics of a single 10 mg dose of the PF-04171327 tablet in healthy volunteers.

Arms Assigned Interventions
Experimental: PF-04173127 Drug: PF-04171327
PF-0417327 will be provided as an oral solution administered at doses of 1, 3, 10 and 30 mg. If an additional cohort is required, the dose selected will not exceed 100 mg. Solution will be administered once daily for 14 days.
Active Comparator: Prednisolone Drug: Prednisolone
Oral doses of prednisolone (5, 10, and 20 mg) will be administered to the first three cohorts. The fourth cohort will receive between 1 and 20 mg to be determined after the third cohort completes dosing. If an additional cohort is required, the dose selected will not exceed 40 mg. Prednisolone tablets will be administered once daily for 14 days
Placebo Comparator: Placebo Drug: Placebo
Tablets similar in appearance to prednisolone will be administered once daily for 14 days.
Sham Comparator: Solution Placebo Drug: Placebo Solution
Placebo solution will be administered to those volunteers who are randomized to the placebo or prednisolone arms. This will be administered orally each day for 14 days.
Experimental: PF-04171327 Tablet Drug: PF-04171327 Tablet
A single 10 mg dose of PF-04171327 tablet formulation will be administered orally to volunteers in Part 2 of this study.
