Interventions

PF-04937319DRUG

Subjects will be dosed with PF-04937319 for 14 days. The doses planned are 10, 30, 100 and 300 mg QD. All doses will be administered as tablets (10 and 100 mg strengths). In each Cohort, 9 patients will receive PF 04937319 and 3 will receive placebo. An additional cohort of 12 patients (9 active, 3 placebo) may be performed to explore a QD or BID dose. The dose for this additional cohort could be a dose already studied or a new dose that is within the exposure stopping criteria.

PlaceboDRUG

Placebo to match PF-04937319 will be provided. Subjects will be dosed for 14 days. In each cohort 9 subjects will receive PF-04937319 and 3 will receive placebo.
