About this study

Official title: A Phase 1, Open-Label 4 Sequence 4 Period Crossover Study In Healthy Volunteers To Estimate The Effect Of Active Pharmaceutical Ingredient Particle Size And Lubrication On The Bioavailability Of A Single 125 Mg Dose Of Palbociclib (PD-0332991) Administered Under Fasted Conditions

The particle size of the active ingredient may impact dissolution rate in the gastro intestinal tract and hence the amount of drug available for absorption. Similarly, differences in the percentage of the excipients used in the formulated capsules may affect dissolution rate. The purpose of this study is to estimate the effect that particle size and percentage of excipients could have in drug absorption, which will improve the manufacturing process of the formulated capsules.

What is being measured

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

  1. Area under the Concentration-Time Curve (AUC) from time zero extrapolate to infinite time

    AUC is a measure of the serum concentration of the drug over time. It is used to characterize drug absorption.

    Measured: 7 days

  2. Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-t)]

    AUC (0-t)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-t)

    Measured: 7 days

  3. Maximum Observed Plasma Concentration (Cmax)

    Measured: 2 days

Secondary outcomes (6)
  1. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

    Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

    Measured: 7 days

  2. Area under the Concentration-Time Curve (AUC) from 0 to 72

    AUC is a measure of the serum concentration of the drug over time. It is used to characterize drug absorption.

    Measured: 3 days

  3. Apparent Oral Clearance (CL/F)

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

    Measured: 7 days

  4. Time to Reach Maximum Observed Plasma Concentration (Tmax)

    Measured: 2 days

  5. Apparent Volume of Distribution (Vz/F)

    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

    Measured: 7 days

  6. Plasma Decay Half-Life (t1/2)

    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

    Measured: 7 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Palbociclib Formulation Reference and Palbociclib Formulation Test in people with Healthy, 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 3 inclusion and 6 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 Aug 2013. 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?

Area under the Concentration-Time Curve (AUC) from time zero extrapolate to infinite time (time frame: 7 days). The study lists 3 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 Aug 2013.
