What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PF-04991532Drug
The tentative dosing schedule is 30, 100, 300, 600, 1200, and 2000 mg. Doses shown may be adjusted upwards or downwards and may be adjusted to include intermediate doses. All doses will be administered as extemporaneously-prepared powder in capsule (PIC) formulation.
PlaceboDrug
Placebo to match PF-04991532 will be provided
| Study group | Role | What they receive |
|---|---|---|
| PF-04991532 | Experimental | This will be a crossover study with 2 cohorts and an interleaving design with placebo substitution. The study will be conducted over 4 treatment periods in Cohort 1 (n=9) and over 3 treatment periods in Cohort 2 (n=9). Six subjects will be allocated to receive PF-04991532 and three subjects will be allocated to receive placebo treatment during each dosing period, except for the 4th period of Cohort 1. The 4th period of Cohort 1 will be dedicated to assess the effect of food on PF-04991532 PK parameters at one of the doses previously tested in Cohort 1; hence all 9 subjects will be dosed with PF-04991532 in an open-label fashion. A washout period of at least 7 days will occur between each dose. Receives: Drug: PF-04991532 |
| Placebo | Placebo comparator | This will be a crossover study with 2 cohorts and an interleaving design with placebo substitution.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PF-04991532 in people with Diabetes Mellitus and Diabetes Mellitus, Type 2, 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 2 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 5 Aug 2010. 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?
Safety and Tolerability Endpoints: physical exams, AE monitoring, 12-lead ECGs, continuous cardiac monitoring, vital sign and clinical safety laboratory (including frequent glucose assessments via glucometer) measurements. (time frame: 1 month). 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 5 Aug 2010.
