About this study

Official title: A Phase 1, Open-Label Fixed-Sequence 2-Period Crossover Study Of Palbociclib (pd-0332991) In Healthy Volunteers To Estimate The Effect Of Antacid Treatment On The Bioavailability Of A 125 Mg Single Dose Of Six Experimental Formulations Of Palbociclib Relative To Palbociclib Administration Alone Under Fasted Conditions

This study will investigate whether concurrent administration of rabeprazole, an antacid known as a proton pump inhibitor, alters the absorption of the drug palbociclib when given as one of six experimental formulations.

Read the detailed description

This will be a 6 cohort study investigating one experimental formulation of palbociclib in each of the six cohorts of 10 healthy subjects. Each cohort will receive two treatments in a fixed-sequence. In Period 1, all subjects will receive a single 125mg dose of palbociclib alone and undergo serial pharmacokinetic blood sampling for up to 120 hours post-dose. In Period 2, all subjects will receive daily 40mg doses of Rabeprazole for 7 consecutive days, and approximately 4 hours after the Day 7 rabeprazole dose each subject will receive a single 125mg dose of palbociclib. Subjects will undergo serial pharmacokinetic blood sampling up to 120 hours post-dose.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Palbociclib AloneDrug

    Also called Palbociclib, PD-0332991

    In Period 1 of each Cohort, a single 125 mg dose of palbociclib will be administered alone in a fasted state, and subjects will undergo serial pharmacokinetic blood sampling for up to 120 hours post-dose.

  • Palbociclib + RabeprazoleDrug

    Also called Palbociclib, PD-0332991, Rabeprazole, Aciphex, Proton Pump Inhibitor, PPI

    In Period 2 of each Cohort, subjects will receive daily 40 mg oral doses of the proton pump inhibitor rabeprazole on 7 consecutive days. Approximately 4 hours after the last rabeprazole dose a single 125 mg dose of palbociclib will be administered alone in a fasted state, and subjects will undergo serial pharmacokinetic blood sampling for up to 120 hours post-dose.

What is being measured

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

  1. AUCinf

    Area under the concentration-time curve from time zero to infinity.

    Measured: Pre-dose to 120 hours post-dose

  2. Cmax

    Maximum observed plasma concentration

    Measured: Pre-dose to 120 hours post-dose

Secondary outcomes (5)
  1. AUClast

    Area under the concentration-time curve from time zero to the time of the last quantifiable concentration.

    Measured: Pre-dose to 120 hours post-dose

  2. CL/F

    Apparent oral clearance from plasma

    Measured: Pre-dose to 120 hours post-dose

  3. Tmax

    Time of the maximum observed concentration post-dose.

    Measured: Pre-dose to 120 hours post-dose

  4. Vz/F

    Apparent volume of distribution

    Measured: Pre-dose to 120 hours post-dose

  5. t1/2

    Terminal phase half-life

    Measured: Pre-dose to 120 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Palbociclib Alone and Palbociclib + Rabeprazole in people with Healthy, run by Pfizer at 3 sites 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 3 inclusion and 4 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 28 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

AUCinf (time frame: Pre-dose to 120 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 28 May 2015.
