Study Details

Study Description

Brief Summary

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.

Outcome Measures

Primary Outcome Measures

  1. Number of participants with adverse events as a measure of safety and tolerability. [3 days]

  2. Pharmacokinetics of single doses of PF-05105679 as measured by plasma concentrations- Cmax, Tmax, half life, AUC last, AUC(0-24) and MRT [3 days]

Secondary Outcome Measures

  1. Average AUC2min VAS (cold pressor test) of PF-05105679. [24 hours]

  2. Cold detection threshold (°C) of PF-05105679. [24 hours]

  3. Cold pain threshold (°C) of PF-05105679. [24 hours]

  4. Stimulus-response function to cold stimuli following menthol application. [24 hours]
