  10. Percent Dipeptidyl-peptidase IV (DPP-IV) Inhibition by Dose (Day 7)

    For analysis of DPP-IV activity, approximately 2 mL of whole blood was collected into a vacuum tube containing ethylenediamine tetraacetic acid (EDTA2K) and centrifuged at approximately 4 degree Celsius, at approximately 2500 revolution per minute (rpm) for 15 minutes. Samples were stored in a freezer at -70 degree Celsius or lower. DPP-IV inhibition was estimated by using the percent change from pre-dose of DPP-IV activity. DPP-IV inhibition was done at pre-dose, 0.5 hr, 2 hr, 3 hr, 4 hr, 6 hr, 8 hr, 12 hr and 24 hr.

    Measured: Day 7

  11. DPP-IV Activity Weighted Mean AUCs at Baseline (Day -1) and Day 7

    For analysis of DPP-IV activity, approximately 2 mL of whole blood was collected into a vacuum tube containing EDTA2K and centrifuged at approximately 4 degree Celsius, at approximately 2500 rpm for 15 minutes. Samples were stored in a freezer at -70 degree Celsius or lower. Double-delta represented active treatment within participant change from Baseline summarized across participants, subtracted from placebo within participant change from Baseline summarized across participants. AUC with respect to these time interval was calculated using linear trapezoidal rule by sum of the areas between each chronological pair of assessments (using observed times). Weighted mean was then determined by dividing AUC by observed length of collection interval (time of last assessment - time of first assessment in hr). Double-delta analysis has been presented in analysis. Unit of measure: Nano mole per minute per milliliter (nmol/min/mL).

    Measured: Baseline (Day -1) and Day 7

    For the analysis of active GLP-1 concentrations, approximately 3 mL of whole blood was collected into a vacuum tube containing DPP-IV inhibitor, and then centrifuged in a refrigerated centrifuge at approximately 4 degree Celsius, at approximately 2500 rpm for 15 minutes. Samples were stored in a freezer at -70 degree Celsius or lower. Double-delta represented the active treatment within participant change from Baseline summarized across participants, subtracted from placebo within participant change from Baseline summarized across participants. AUC with respect to these time interval was calculated using linear trapezoidal rule by sum of the areas between each chronological pair of assessments (using observed times). Weighted mean was then determined by dividing AUC by observed length of collection interval (time of last assessment - time of first assessment in hr).

Secondary outcomes (1)
  1. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is serious corresponding to those listed in above definition.

    Measured: Up to post-study screen (Follow-up [7 days after the last dose of study medication])

What is this clinical trial studying?

A Phase 2 study testing GW823093 15mg and GW823093 30mg in people with Diabetes Mellitus, Type 2, run by GlaxoSmithKline at 1 site.

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 1 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 4 Sep 2018. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 19 Mar 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?

Standard Pharmacokinetic (PK) Parameter: Maximum Observed Plasma Drug Concentration (Cmax) (time frame: Day 1 (at 0, 1, 1.5, 2, 3, 4, 6, 8, 12 hours [hr]), Day 2 (0 hr) and Day 7 (0, 0.5, 1, 1.5, 2, 4, 6, 8, 12 and 24 hr)). The study lists 16 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 4 Sep 2018.
