About this study

Official title: A Phase 1, Double Blind, Sponsor Open, Randomized, Placebo Controlled, Crossover, Single Oral Dose Escalation Study To Investigate The Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Of PF-06412562 In Healthy Subjects

This study will determine the safety and tolerability of PF-06412562 given orally to healthy volunteers. To determine the optimal dose for future studies, the concentration of the drug over time will be determined by periodic blood samples. The rate of eye blinks will be measured as an indicator of PF-06412562 action on the receptors of interest in the brain.

What participants receive

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

  • PF-06412562Drug

    Single doses, given by oral solution, starting at 0.5 mg up to a possible maximum of 150 mg. The subject will have been fasted for 10 hours prior to the single dose. Two doses, 120 mg and 150 mg, will be split into 3 doses such that the total dose is given over 8 hours (i.e. t = 0, 4, and 8 hours). For each dosing period, 2 subjects will be given a placebo as a comparator. One dose will be given in the fed state.

  • PF-06412562Drug

    It is believed that for increasing doses of this compound the eye blink rate (EBR) will also increase. This arm will use EBR measurement technology to verify this hypothesis. In each dosing period, 4 subjects will be given a placebo as a comparator.

What is being measured

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

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

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

    Measured: 0, 0.5, 1, 1.5, 2, 4, 5, 6, 8, 9, 10, 12, 16, 24, 32 hours post-dose

  2. 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: 0, 0.5, 1, 1.5, 2, 4, 5, 6, 8, 9, 10, 12, 16, 24, 32 hours post-dose

  3. Maximum Observed Plasma Concentration (Cmax)

    Measured: 0, 0.5, 1, 1.5, 2, 4, 5, 6, 8, 9, 10, 12, 16, 24, 32 hours post-dose

  4. Area Under the Curve From Time Zero to Extrapolated Infinite Time

    AUC = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time. It is obtained from AUC (0 - t) plus AUC (t - 8).

    Measured: 0, 0.5, 1, 1.5, 2, 4, 5, 6, 8, 9, 10, 12, 16, 24, 32 hours post-dose

  5. 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: 0, 0.5, 1, 1.5, 2, 4, 5, 6, 8, 9, 10, 12, 16, 24, 32 hours post-dose

  6. 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: 0, 0.5, 1, 1.5, 2, 4, 5, 6, 8, 9, 10, 12, 16, 24, 32 hours post-dose

  7. Measurement of Cognitive Decline by Means of a Computerized Battery of Neuropsychologic Tests

    Change from baseline cognitive performance

    Measured: 0, 1, 4, 8, 12 hours post-dose

  8. Eye Blink Rate

    Measurement of eye blink rate for a given dose at time of predicted maximum blood concentration of the compound.

    Measured: 0, 1, 2, 4 and 8 hours

  9. Area Under the Curve From Time Zero to 24 hours

    Area under the plasma concentration time-curve from zero to 24 hours

    Measured: 0, 0.5, 1, 1.5, 2, 4, 5, 6, 8, 9, 10, 12, 16, 24 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06412562 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 5 inclusion and 2 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 23 May 2014. 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. Some participants in this study may receive a placebo. 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 Decay Half-Life (t1/2) (time frame: 0, 0.5, 1, 1.5, 2, 4, 5, 6, 8, 9, 10, 12, 16, 24, 32 hours post-dose). The study lists 9 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 23 May 2014.
