The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Pfizer
  Purpose
This is a two part study. The purpose of the first part (Part A) is the evaluation of the pharmacokinetics, safety and tolerability after single ascending dose of PF-05105679. The second part (Part B) of this study will focus on the exploratory pharmacodynamics of PF-05105679 using pharmacodynamics markers (cold detection) in healthy volunteers. The doses selected in Part B will have been administered previously in the Part A of the study.

Official Title: A Phase I, Randomized, Placebo-Controlled, Dose Escalating Cross Over Study To Evaluate The Safety, Toleration, Pharmacokinetics And Pharmacodynamics Of PF-05105679 Under Fasted Conditions In Healthy Volunteers

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Number of participants with adverse events as a measure of safety and tolerability. [ Time Frame: 3 days ]
  • Pharmacokinetics of single doses of PF-05105679 as measured by plasma concentrations- Cmax, Tmax, half life, AUC last, AUC(0-24) and MRT [ Time Frame: 3 days ]

Secondary Outcome Measures:
  • Average AUC2min VAS (cold pressor test) of PF-05105679. [ Time Frame: 24 hours ]
  • Cold detection threshold (°C) of PF-05105679. [ Time Frame: 24 hours ]
  • Cold pain threshold (°C) of PF-05105679. [ Time Frame: 24 hours ]
  • Stimulus-response function to cold stimuli following menthol application. [ Time Frame: 24 hours ]
