Multiple Dose Escalation Trial Of PF-04308515 In Healthy Volunteers

This study has been completed.
Information provided by:
Pfizer Identifier:
First received: March 11, 2010
Last updated: July 21, 2011
Last verified: July 2011
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-04308515 in healthy volunteers for 14 days as well as one oral dose of a tablet formulation administered for 1 day.

Condition Intervention Phase
Drug: PF-04308515
Drug: Placebo
Drug: PF-04308515 Tablet
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Basic Science
Official Title: A Phase 1, Placebo-Controlled, Multiple-Dose Escalation Trial Evaluating The Safety, Tolerability, Pharmacokinetics, And Pharmacodynamics Of PF-04308515 (Part 1), And A Single Dose Pharmacokinetic Assessment Of A PF-04308515 Tablet Formulation (Part 2), In Healthy Volunteers

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Safety and tolerability of multiple doses of PF-04308515 as assessed by adverse event reporting, clinical laboratory results, vital signs, physical examinations and electrocardiograms (ECGs). [ Time Frame: 14 days ]
  • Characterization of pharmacokinetic parameters of PF-04308515 after multiples doses which will include: Cmax, Tmax, AUC, CL/F, Vz/F, t1/2. Urinary excretion including AE% and CLr will be assessed at steady state. [ Time Frame: 14 days ]
  • Change from baseline will be utilized to assess PF-04308515's pharmacodynamic effect on biochemical and metabolic biomarkers after 14 days of dosing. [ Time Frame: 14 days ]
  • For the tablet pharmacokinetics:Cmax, Tmax, AUClast, AUCinf, CL/F, Vz/F, t1/2 will be calculated from the PF-04308515 plasma concentration versus time data. [ Time Frame: 1 day ]
  • Safety and tolerability of 1 oral dose of a tablet formulation of PF-04308515 as assessed by adverse event reporting, clinical laboratory results, vital signs, physical examinations and electrocardiograms (ECGs). [ Time Frame: 1 day ]

Enrollment: 58

Arms Assigned Interventions
Experimental: (Part 1) PF-04308515 Drug: PF-04308515
PF-04308515 will be provided as an oral solution administered at doses of 3, 10, 30 and 100 mg. If an optional cohort is needed the dose would not exceed the established toxicokinetic exposure limits. Solution will be administered orally once daily for 14 days.
Placebo Comparator: (Part 1) Solution Placebo Drug: Placebo
Placebo solution will be administered to those volunteers who are randomized to the placebo arm. Placebo solution will be administered orally once daily for 14 days.
Experimental: (Part 2) PF-04308515 Tablet Drug: PF-04308515 Tablet
Tablet formulation to administer a 20 mg dose will be administered to volunteers in Part 2. The study medication will be administered orally once daily for 1 day.
