SINGLE DOSE: Single Dose, Dose Escalation Healthy Volunteers Study Of PF-05105679
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.
