Clinical Study to Evaluate Pharmacokinetics and Safety of PF-06700841 After Single and Multiple Oral Doses as Modified Release Formulations

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to evaluate the pharmacokinetics (PK), safety, and tolerability of PF-06700841 following single and multiple oral doses as modified release (MR) formulations in healthy, adult participants under fasted and fed conditions. The objective of Part A is to evaluate the relative bioavailability and food effect of 2 new MR formulations, MR1 and MR2. The objective of Part B is to evaluate the PK and safety/tolerability of MR3 formulation following multiple dose administration over a 7-day period. Overall, results from both parts will facilitate further development of an MR formulation for future clinical studies.
