Study to Evaluate Pharmacokinetics of A Modified Release Formulation of PF-06650833 in Healthy Subjects
- Registration Number
- NCT02609139
- Lead Sponsor
- Pfizer
- Brief Summary
This is a Phase 1, open-label, single-dose, within-cohort randomized, 2-way crossover study to evaluate the PK of orally administered PF-06650833 modified release tablets under fasted and high fat meal fed conditions in healthy subjects.
- Detailed Description
This is the third study of PF-06650833. The goals of the study are to assess the PK in healthy subjects of single doses of modified release (MR) tablets of PF-06650833 when orally administered under fasting and high fat meal fed conditions.
