This is a Phase 1, fixed sequence, multiple dose, open label study of the effect of PF-06826647 on oral contraceptive (OC) pharmacokinetics (PK) and vice versa in healthy female participants. A total of approximately 15 healthy female participants will be enrolled and dosed to achieve at least 12 participants completing the study.

Area Under the Plasma Concentration-Time Profile From Time Zero To End of Dosing Interval (AUGtau) of Ethinyl Estradiol (EE)
Area under the plasma concentration time profile from time 0 to end of dosing interval (AUCtau), where dosing interval is 24 hours.
Time frame: Day 14 in Period 2 (Period 2 is 14 days) and Day 16 in Period 3 (Period 3 is 17 days)
Area Under the Plasma Concentration-Time Profile From Time Zero To End of Dosing Interval (AUGtau) of Levonorgestrel (LN)
Area under the plasma concentration time profile from time 0 to end of dosing interval (AUCtau), where dosing interval is 24 hours.
Time frame: Day 14 in Period 2 (Period 2 is 14 days) and Day 16 in Period 3 (Period 3 is 17 days)
Area Under the Plasma Concentration-Time Profile From Time Zero Extrapolated to Infinite Time (AUCinf) of PF-06826647
AUCinf is calculated by AUClast + (Clast\*/kel), where AUClast is the area under the plasma concentration-time profile from time 0 to the time of the last quantifiable concentration, Clast\* is the predicted plasma concentration at the last quantifiable time point estimated from the log-linear regression analysis, and kel is the terminal phase rate constant calculated by a linear regression of the log-linear concentration-time curve.
Time frame: Day 1 in Period 1 (Period 1 is 2 days) and Period 3 (Period 3 is 17 days)
Maximum Plasma Concentration (Cmax) of PF-06826647
Cmax will be observed directly from data.
Time frame: Day 1 in Period 1 (Period 1 is 2 days) and Period 3 (Period 3 is 17 days)
Number of Participants With Treatment-emergent Adverse Events (TEAEs)
An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A serious adverse event (SAE) is defined as any untoward medical occurrence at any dose that results in death; is life threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; results in congenital anomaly/birth defect. AEs include both SAEs and AEs. TEAEs are AEs that occur following the start of treatment or AEs increasing in severity during treatment.
