The purpose of this study is to evaluate the effect of food intake on PF-04136309 pharmacokinetics (PK) following a single dose at 1000 mg.

The present study will be conducted in healthy adult subjects. The single dose of 1000 mg has been shown to be safe in a previous study in healthy subjects. To evaluate the effect of food on PF-04136309 PK at the dose of 1000 mg, which is the maximum dose that may be evaluated in the multiple dose setting in patients, will provide information to guide the dose administration in regards to food intake at relevant therapeutic dose levels for further studies in patients.
