About this study

Official title: 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)
  • 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
Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Plasma PF-04965842 PK parameters

    AUCinf

    Measured: hour 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48 hours post-dose

  2. Plasma PF-04965842 PK parameters

    Cmax

    Measured: hour 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48 hours post-dose

Secondary outcomes (3)
  1. number of subjects with treatment-emergent adverse event

    Measured: baseline until Period 4 study day 35

  2. number of subjects with significant change from baseline in Supine Blood pressure, pulse rate and oral temperature

    The actual and the change from baseline values will be summarized by treatment. These data will be listed and out of range values will be summarized

    Measured: baseline until Period 4 study day 3

  3. number of subjects with significant Changes from baseline for the ECG parameters QT interval, heart rate, QTc interval, PR

    Changes from baseline for the ECG parameters QT interval, heart rate, QTc interval, PR interval, and QRS complex will be summarized by treatment and time. The number (%) of participants with maximum postdose QTc values and maximum increases from baseline in the following categories will be tabulated by treatment

    Measured: baseline until Period 4 study day 3

Model description
This is a Phase 1 randomized, open label, single-dose, crossover study in healthy participants to estimate the rBA of the commercial formulation of PF-04965842 (Test formulation 1) and the variant formulation with slower dissolution (Test formulation 2) compared to the Phase 3 formulation (Reference formulation), to demonstrate the BE of the commercial formulation relative to the Phase 3 formulation, and to estimate the effect of food on the rBA of the commercial formulation after a single 200 mg oral dose.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing P3-Fast, Comm-Fast and Vari-Fast in people with Dermatitis, Atopic, run by Pfizer at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma PF-04965842 PK parameters (time frame: hour 0, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48 hours post-dose). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2020.
