Outcome Measures

Primary Outcome Measures

  1. midazolam Area Under the Curve from time 0 to last quantifiable concentration (AUClast) in Period 1 [0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24 hrs post-dose]

    the plasma midazolam AUC from 0 to tlast (time of last quantifiable concentration) when a single oral midazolam dose given alone

  2. midazolam Cmax on Day 1 in Period 1 [0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24 hrs post-dose]

    the midazolam Cmax when single oral midazolam dose given alone

  3. midazolam Area Under the Curve from time 0 to infinite (AUCinf) in Period 1 [0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24 hrs post-dose]

    the plasma midazolam AUC from 0 to infinity when a single oral midazolam dose given alone

  4. midazolam AUClast in Period 2 [0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 48 hrs post-dose]

    the plasma midazolam AUC from 0 to tlast (time of the last quantifiable concentration) when a single oral midazolam given in presence of steady state PF-06751979

  5. midazolam Cmax in Period 2 [0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 48 hrs post-dose]

    the midazolam Cmax when a single oral midazolam given in presence of steady state PF-06751979

  6. midazolam AUCinf in Period 2 [0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 48 hrs post-dose]

    the plasma midazolam AUC from 0 to infinity when a single oral midazolam given in presence of steady state PF-06751979

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years to 55 Years
Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
Yes
Inclusion Criteria:
  • Healthy female subjects of nonchildbearing potential and male subjects who, at the time of screening, are between the ages of 18 and 55 years, inclusive. Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure (BP) and pulse rate (PR) measurement, 12-lead electrocardiogram (ECG), or clinical laboratory tests.

  • Body mass index (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, (including alcoholic liver disease, nonalcoholic steatohepatitis (NASH), autoimmune hepatitis, and hereditary liver diseases), psychiatric, neurological, 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).

  • Treatment with an investigational drug within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of investigational product (whichever is longer).

  • Subjects who have previously received PF-06751979.

  • Fertile male subjects who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for at least 28 days after the last dose of investigational product.

  • Use of prescription or nonprescription drugs and dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of investigational product. As an exception, acetaminophen/paracetamol may be used at doses of <=1 g/day. Limited use of nonprescription medications that are not believed to affect subject safety or the overall results of the study may be permitted on a case-by-case basis following approval by the sponsor.

  • Herbal supplements and hormone replacement therapy must have been discontinued at least 28 days prior to the first dose of investigational product.

  • Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing.

  • History of hypersensitivity to midazolam or any other benzodiazapine.

  • Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product 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.
