administration or may interfere with the interpretation of study results and, in the
judgment of the investigator, would make the subject inappropriate for entry into this
study.

A Study to Determine the Effects of PF-04965842 on the Pharmacokinetics of Oral Contraceptive Steroids in Healthy Female Subjects
A Phase 1, Randomized, Open-label, 2-way Crossover Study to Estimate the Effect of Multiple Dose PF-04965842 on the Pharmacokinetics of Single-dose Oral Contraceptive Steroids in Healthy Female Subjects
This is a Phase 1, randomized, 2 way crossover, open-label study of the effect of multiple-dose PF 04965842 on single-dose OC PK in healthy female subjects. Subjects will be randomized to 1 of 2 treatment sequences. A total of 16 healthy female subjects (8 in each treatment sequence) will be enrolled in the study. Each treatment sequence will consist of 2 periods.

In Treatment Sequence 1, Period 1 Day 1, subjects will be dosed with a single administration of OC in the form of 1 PORTIA (ethyinyl estradiol [EE] and levonorgestrel [LN]) or equivalent tablet, orally. OC (EE and LN) PK will then be assessed at pre dose and over 48 hours after OC dosing. Period 1 will be immediately followed by Period 2 with no washout. The 48 hours post-OC dose PK sample for Period 1 must be collected prior to receiving the first dose of PF 04965842 in Period 2. In Period 2, subjects will be dosed with 200 mg PF 04965842 PO QD for 9 days followed by administration of a single dose of OC oral tablet immediately after administration of a 200 mg dose of PF-04965842 on the morning of Day 10. OC PK in Period 2 will be assessed at pre dose and over 48 hours after OC dosing. Dosing with 200 mg PF 04965842 PO QD will continue until Day 11.

In Treatment Sequence 2, Period 1, subjects will be dosed with 200 mg PF 04965842 PO QD for 9 days followed by administration of a single dose of OC oral tablet immediately after administration of a 200 mg dose of PF-04965842 on the morning of Day 10. OC PK will be assessed at pre dose and over 48 hours following OC dosing. Dosing with 200 mg PF 04965842 PO QD will continue until Day 11. Subjects will then undergo a washout period of at least 10 days (Day -1 of Period 2 starts 10 days after Day 12 of Period 1). In Period 2 subjects will be dosed with a single OC administration on Day 1. OC PK will then be assessed at pre dose and over 48 hours after OC dose.

Interventional
Phase 1
Allocation: Randomized
Intervention Model: Crossover Assignment
Intervention Model Description:

Natural log transformed AUCinf, AUClast, and Cmax of EE and LN will be analyzed separately using a mixed effect model with sequence, period and treatment as fixed effects and subject within sequence as a random effect. Estimates of the adjusted mean differences (Test Reference) and corresponding 90% CIs will be obtained from the model. The adjusted mean differences and 90% CIs for the differences will be exponentiated to provide estimates of the ratio of adjusted geometric means (Test/Reference) and 90% CIs for the ratios. OC (EE and LN) alone will be the Reference treatment, while the OC (EE and LN) coadministered with PF 04965842 will be the Test treatment.

The absent of an effect of PF 04965842 on OC (EE and LN) will be concluded if the lower bound of 90% confidence interval for the ratio of adjusted geometric mean for AUCinf is ?80%.
