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

  1. Number of Participants With Dose Limiting or Intolerable Treatment Related Adverse Events (AEs)

    Number of participants with dose limiting or intolerable treatment related adverse events (AEs) was reported. An AE was any untoward medical occurrence in a clinical investigation subject administered a product or medical device; the event need not necessarily have a causal relationship with the treatment or usage.

    Measured: Day 1 through Day 127

  2. Number of Participants With All-Causality Treatment Emergent Adverse Events(TEAEs)

    Number of participants with all-causality treatment emergent adverse events were reported. An AE was any untoward medical occurrence in a clinical investigation subject administered a product or medical device; the event needed not necessarily have a causal relationship with the treatment or usage. TEAEs were those AEs with initial onset or increasing in severity after the first dose of study drug. TEAEs included both serious and non-serious AE

    Measured: Day 1 through Day 127

  3. Number of Participants With Treatment-Related TEAEs

    Number of participants with treatment-related TEAEs were reported. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug.

Secondary outcomes (7)
  1. Area Under Concentration-Time Curve From Time Zero to Time Tau(AUCtau) on Day 1 and Day 71

    Area under the concentration-time profile from time 0 to time tau (τ), the dosing interval, where tau = 168 hours for once a week dosing; tau = 336 hours for once every 2 weeks dosing. On Day 1, 3 participants in cohort 1 had reportable AUCtau values. On Day 71, 6 participants in cohort 1 and 2 participants in cohort 4 had reportable AUCtau values

    Measured: 0,1,4 hours post-dose on Day 1 and Day 71

  2. Apparent Oral Clearance (CL/F) on Day 71

    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. On Day 71, 6 participants in cohort 1 had reportable CL/F values

    Measured: 0,1,4 hours post-dose on Day 71

  3. Maximum Observed Plasma Concentration (Cmax) on Day 1 and Day 71

    Maximum serum concentration was observed directly from data on Day 1 and Day 71. On Day 71, 2 participants in cohort 4 had reportable Cmax values

    Measured: 0, 1, 4 hours post-dose on Day 1 and Day 71

  4. Time to Reach Maximum Observed Plasma Concentration (Tmax) on Day 1 and Day 71

    Time to reach maximum observed plasma concentration was observed directly from data as time of first occurrence on Day 1 and Day 71. On Day 71, 2 participants in cohort 4 had reportable Tmax values

    Measured: 0, 1, 4 hours post-dose on Day 1 and Day 71

  5. Plasma Decay Half-Life (t1/2) on Day 71

    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half. On Day 71, 2 participants in cohort 1, 5 participants in cohort 2, and 7 participants in cohort 3 had reportable values for t1/2

    Measured: 0, 1, 4 hours post-dose on Day 71

  6. Apparent Volume of Distribution (Vz/F) on Day 71

    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. On Day 71, 1 participant in cohort 1, 5 participants in cohort 2, and 7 participants in cohort 3 had reportable Vz/F values

    Measured: 0, 1, 4 hours post-dose on Day 71

  7. Accumulation Ratio (Rac) on Day 71

    Accumulation ratio was calculated from AUCinf at last dose/AUCinf at first dose, where AUCinf is defined as area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). It is obtained from AUC (0-t) plus AUC (t-inf). On Day 71, 3 participants in cohort 1 had reportable Rac values.

    Measured: 0, 1, 4, hours post-dose on Day 71

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06342674 Dose A, PF-06342674 Dose B and PF-06342674 Dose C in people with Diabetes Mellitus, Type 1, run by Pfizer at 21 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 3 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 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. 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?

Yes. Results are posted in the registry (first posted 3 Aug 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Dose Limiting or Intolerable Treatment Related Adverse Events (AEs) (time frame: Day 1 through Day 127). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02038764, which also lists 1 linked publication.

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 3 Aug 2018.
