What is being measured

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

  1. Area Under the Plasma Concentration-Time Profile From Time Zero to Time of the Last Quantifiable Concentration (AUC Last) (Dose Normalized to 1 mg) and Absolute Oral Bioavailability (F) (Period 1)

    AUC0-inf is a measure of the mean concentration levels of drug in the plasma after the drug dose. An absolute bioavailability provides information on the amount of a drug reaching the systemic circulation and can be determined by comparing the plasma concentration-time-curves (area under the curve) of a compound after oral application of that compound to that after intravenous application of the same compound.

    Measured: Oral: 0, 15 and 30 min., and at 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, and 72 hrs. after oral dose; IV: -5 min. (predose), 0 (end of infusion), and at 10, 20, 30, and 45 min. and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 11, 23, 47, 71, and 95 hrs. after end of infusion

    Systemic clearance is a calculation of the rate at which a drug is removed from plasma via renal, hepatic and other clearance pathways, expressed as volume (milliliters) per unit of time (minutes). Geometric coefficient of variation is given as the percent coefficient of variation. This outcome measure is for the Ertugliflozin intravenous drug profile only so no participants were analyzed in the Ertugliflozin oral arm.

    Measured: Oral: 0, 15 and 30 min., and at 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, and 72 hrs. after oral dose; IV: -5 min. (predose), 0 (end of infusion), and at 10, 20, 30, and 45 min. and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 11, 23, 47, 71, and 95 hrs. after end of infusion

    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 is influenced by the fraction absorbed. Geometric coefficient of variation is given as the percent coefficient of variation. This outcome measure is for the Ertugliflozin oral drug profile only so no participants were analyzed in the 14^C-Ertugliflozin 100 ug intravneous arm.

    Measured: Oral: 0, 15 and 30 min., and at 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, and 72 hrs. after oral dose; IV: -5 min. (predose), 0 (end of infusion), and at 10, 20, 30, and 45 min. and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 11, 23, 47, 71, and 95 hrs. after end of infusion

    Steady-State Volume of Distribution is the theoretical volume that the total amount of administered drug would have to occupy (if it were uniformly distributed), to provide the same concentration as it is in blood plasma at steady state. Geometric coefficient of variation is given as the percent coefficient of variation. This outcome measure is for the Ertugliflozin intravenous drug profile only so no participants were analyzed in the Ertugliflozin oral arm.

    Measured: Oral: 0, 15 and 30 min., and at 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, and 72 hrs. after oral dose; IV: -5 min. (predose), 0 (end of infusion), and at 10, 20, 30, and 45 min. and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 11, 23, 47, 71, and 95 hrs. after end of infusion

  10. Pharmacokinetic Parameter: Fraction Absorbed (Fa, Radioactivity in Urine) (Periods 1 and 2) (Dose Normalized)

    Fraction absorbed is the fraction of the total ertugliflozin dose absorbed, regardless of the fate of that dose after absorption (i.e., metabolism, degradation, etc). Fraction Absorbed was estimated as the ratio of total radioactivity (dose normalized) excreted into the urine (from time zero to the time of last measurable concentration) following oral and IV administration of 14^C-ertugliflozin. Fraction of 14^C dose recovered in urine = 14^C total in urine in dpm/14^C total in dose in dpm

    Measured: Part 1: pre- IV dose, 0-11 and 11-23 hrs. post IV dose, and 23 - 47, 47 - 71 and 71 - 95 hrs. until Day 5; Part 2: predose, 0-12 and 12-24 hrs. post dose, and then 24-hour intervals until Day 5

  11. Number of Participants Who Experienced an Adverse Event (Periods 1 and 2)

    An adverse event (AE) is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study.

    Measured: Up to approximately 33 days

  12. Number of Participants Discontinuing Study Drug Due to Adverse Events (Periods 1 and 2)

    An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study.

    Measured: Up to approximately 16 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Unlabeled ertugliflozin for oral use, 14^C-labeled ertugliflozin for IV use and 14^C-labeled ertugliflozin for oral use in people with Type 2 Diabetes Mellitus, run by Merck Sharp & Dohme LLC.

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 14 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 18 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 17 Feb 2016). 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?

Area Under the Plasma Concentration-Time Profile From Time Zero to Time of the Last Quantifiable Concentration (AUC Last) (Dose Normalized to 1 mg) and Absolute Oral Bioavailability (F) (Period 1) (time frame: Oral: 0, 15 and 30 min., and at 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, and 72 hrs. after oral dose; IV: -5 min. (predose), 0 (end of infusion), and at 10, 20, 30, and 45 min. and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 11, 23, 47, 71, and 95 hrs. after end of infusion). 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 NCT02411929, which also lists 2 linked publications.

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 18 Sep 2018.
