About this study

Official title: A Phase 1, Open-Label, Single Dose Study To Evaluate The Pharmacokinetics, Safety, And Tolerability Of PD 0332334 In Subjects With Various Degrees Of Renal Function

  1. To investigate the effect of kidney function on the elimination of a single dose of PD 0332334 from the body.
  2. To investigate the safety and tolerability of a single dose of PD 0332334 in patients with impaired kidney function.
Read the detailed description

Additional Study Purpose Details: Investigation of the pharmacokinetics, safety, and tolerability of a single dose of PD 0332334 in patients with impaired renal function.

On February 23rd 2009, a decision to terminate further development for PD 0332334 was communicated to investigators in this study. The decision to terminate this study was not based on any safety concerns.

What is being measured

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

  1. maximum plasma concentration (Cmax), time of maximum plasma concentration (Tmax), and apparent clearance from plasma (CL/F)

    Measured: 1 day

  2. amount of PD 0332334 eliminated unchanged in urine during the 96-hour collection period (Ae96)

    Measured: 5 days

  3. PD 0332334 area under the curve from 0 to infinity (AUCinf), PD 0332334 area under the curve from 0 to last quantifiable concentration (AUClast),

    Measured: 5 to 17 days depending on cohort

  4. PD 0332334 renal clearance (CLr), apparent volume of distribution (Vz/F), terminal half life (t1/2),

    Measured: 5 to 17 days depending on cohort

Secondary outcomes (1)
  1. Adverse events, ECG, physical exams, clinical safety laboratory, and vital signs

    Measured: 5 to 17 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PD 0332334 in people with Renal Insufficiency and Pharmacokinetics, run by Pfizer at 2 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 1 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: stopped early, as of the sponsor's last update on 17 Feb 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 was stopped early (reason given: Please see Detailed Description for termination reason.). Results are not available in the source record.

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?

maximum plasma concentration (Cmax), time of maximum plasma concentration (Tmax), and apparent clearance from plasma (CL/F) (time frame: 1 day). The study lists 4 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 17 Feb 2010.
