Information provided by (Responsible Party):
Pfizer
  Purpose
The purpose of this study is to assess the bioavailability, safety, and tolerability of a modified-release formulation of PF-05180999 relative to an immediate-release formulation in healthy adult subjects. Two doses of the modified-release formulation and one dose of the immediate-release formulation will be evaluated under fasted conditions. One dose of the modified-release formulation will also be evaluated in the presence of food.
