Study of Commercial and Phase 3 of PF-04965842 Formulations, Estimation of Effect of Food on Commercial Formulation

January 6, 2020 updated by: Pfizer

A PHASE 1, OPEN LABEL, SINGLE-DOSE, CROSSOVER STUDY TO EVALUATE THE BIOEQUIVALENCE OF A COMMERCIAL TABLET FORMULATION OF PF-04965842 RELATIVE TO THE PHASE III TABLET FORMULATION UNDER FASTING CONDITIONS AND THE EFFECT OF FOOD ON THE RELATIVE BIOAVAILABILITY OF THE COMMERCIAL TABLET FORMULATION IN HEALTHY PARTICIPANTS

Part A

  • To measure and compare the amount of study drug in the blood after a single 200 mg dose of study drug given as the commercial tablet formulation and the Phase 3 tablet formulation under fasting conditions
  • To measure and compare the amount of study drug in the blood after a single 200 mg dose given as the variant Phase 3 tablet formulation and the Phase 3 tablet formulation under fasting conditions
  • To estimate the effect of food on the amount of study drug in the blood after a single 200 mg dose of the commercial formulation

Part B

• To measure and compare the amount of study drug in the blood after a single 200 mg dose given as the commercial tablet formulation and the Phase 3 tablet formulation under fasting conditions

Parts A & B

  • To collect samples for genotyping (CYP2C19 and CYP2C9 - enzymes that metabolize [break down] certain medications)

    o Genotyping is the collection of a small sample of blood that contains your genes

  • To evaluate the safety and tolerability of the study drug after single 200 mg doses of the three different formulations given to healthy participants
  • To measure the amount of study drug in the blood after single doses of the different formulations
  • To collect exploratory samples for biobanking o Biobanking is the collection and storage of blood samples for possible future testing

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study in healthy participants is to estimate the bioavailability (BA) of the commercial formulation of PF-04965842 and a variant formulation with slower dissolution relative to the Phase 3 formulation, to demonstrate the bioequivalence (BE) of the commercial formulation relative to the Phase 3 formulation, and to estimate the effect of food on the BA of the commercial formulation. This study consists of 2 parts: Part A is to estimate the relative BA (rBA) of single 200 mg doses of the commercial tablet formulation of PF-04965842 and a variant formulation of slower dissolution rate compared to the Phase 3 tablet formulation. The effect of food on the BA of the commercial tablet formulation will also be evaluated. Part B is to establish BE between the Phase 3 and commercial formulations. The study will follow a staged approach as the sample size for BE cannot be determined with currently available information.

Therefore, it is proposed to assess the maximum observed concentration (Cmax) and area under the curve (AUC) ratios between the Phase 3 and commercial formulations as well as the within-participant variability of Cmax and AUC values determined in Part A. Based on the results from Part A, the sample size of Part B will be determined and the decision to proceed to Part B will be made.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
