Brief Title  ICMJE Drug Drug Interaction Study Evaluating the Effect of Fluvoxamine or Fluconazole on PK and Safety of PF-04965842.
Official Title  ICMJE A PHASE 1, OPEN-LABEL, RANDOMIZED, FIXED-SEQUENCE, PARALLEL-COHORT STUDY TO ESTIMATE THE EFFECT OF FLUVOXAMINE OR FLUCONAZOLE, ON THE PHARMACOKINETICS, SAFETY AND TOLERABILITY OF A SINGLE DOSE OF PF-04965842 IN HEALTHY SUBJECTS
Brief Summary A Phase 1, Open Label, Parallel-Cohort, Randomized, Fixed Sequence Study To Evaluate The Pharmacokinetic Drug Drug Interaction Between PF-04965842 and Fkuvoxamine (cohort 1) or Fluconazole (Cohort 2) in healthy subjects.
Detailed Description

A phase 1 study to evaluate the effect of fluvoxamine (a strong CYP2C19 and moderate CYP3A inhibitor) or fluconazole (a strong CYP2C19, moderate CYP2C9 and CYP3A inhibitor) on the pharmacokinetics, safety and tolerability of PF-04965842 in healthy subjects.

This study will be a Phase 1, open label, randomized, fixed-sequence, parallel-cohort study drug-drug interaction study. The study includes 2 periods:

In Period 1: all subjects will receive one single oral dose of 100 mg PF 04965842 tablet. (Treatment A). PK will be evaluated in the first 72 hours post adminstration of PF 04965842.

In Period 2:

  • Cohort 1: subjects will receive fluvoxamine (immediate release tablet 50 mg) once daily for 9 consecutive days; on Day 8, subjects will receive a single oral dose of 100 mg PF 04965842 approximately 3 hours after fluvoxamine administration. (Treatment B). PK will be evaluated in the first 72 hours post administration of PF 04965842.
  • Cohort 2: subjects will receive fluconazole capsule(s) once daily for 7 consecutive days (400 mg on Day 1 and 200 mg on Day 2-7 in Period 2); on Day 5, subjects will receive a single oral dose of 100 mg PF 04965842 approximately 1 hour after fluconazole administration. (Treatment C). PK will be evaluated in the first 72 hours post administration of PF 04965842.
