Inclusion Criteria

  • Male and/or female participants who are healthy as determined by medical evaluation including medical history, full physical examination which includes BP and pulse rate measurements, clinical laboratory tests, and 12-lead ECG.
  • BMI of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lb).

Exclusion Criteria

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, dermatological or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
  • Any condition possibly affecting drug absorption (eg, gastrectomy, cholecystectomy).
  • Systemic therapy with any of the medications that are moderate or strong CYP3A4 and/or CYP2C19 inhibitors within 28 days or 5 half-lives (whichever is longer) or moderate or strong CYP3A and/or CYP2C19 inducers within 28 days or 5 half-lives (whichever is longer) prior to the first dose of investigational product.
  • Known participation in a clinical trial of PF-06651600 within 60 days prior to the first dose of investigational product; participation in any clinical trail of PF-06651600 and the participant experienced AE that led to discontinuation, or had SAE, that in the judgment of the investigator were PF-06651600-related.

Arms & Interventions

Rifampin and PF-06651600 DDI

Experimental

In Period 1, participants will receive a single oral 50 mg dose of PF-06651600. In Period 2, participants will receive rifampin 600 mg QD in the mornings of Day 1 to Day 7, in the morning of Day 8 participants will be administered with rifampin 600 mg 2 hour prior to administration of a single 50 mg oral dose of PF-06651600.
