Influence of Semaglutide on Pharmacokinetics and Pharmacodynamics of Warfarin and Pharmacokinetics of Metformin in Healthy Subjects

March 31, 2017 updated by: Novo Nordisk A/S

An Open-label, One-sequence Cross Over, Single Centre Trial, Investigating the Influence of Semaglutide on Pharmacokinetics and Pharmacodynamics of Warfarin and Pharmacokinetics of Metformin in Healthy Subjects

This trial is conducted in Europe and Asia. The aim of the trial is to investigate the influence of semaglutide on pharmacokinetics (the exposure of the trial drug in the body) and pharmacodynamics (the effect of the investigated drug on the body) of warfarin and pharmacokinetics of metformin in healthy subjects.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Exclusion Criteria:

  • Female who is pregnant, breast-feeding or intends to become pregnant or is of child-bearingpotential and not using adequate contraceptive methods for the duration of the trial and for 5 weeks following the last dose of semaglutide.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Semaglutide administrations
Drug: semaglutide
Subjects will initiate treatment with 0.25 mg for the first four weeks followed by dose doubling every four weeks up to a dose of 1.0 mg.
Drug: placebo
Semaglutide placebo will be administered s.c.
Drug: metformin
For oral administration twice daily, in two periods, each of 3.5 days duration. The first period is initiated before semaglutide treatment and the second period is initiated at the end of semaglutide treatment.
Drug: warfarin
For oral administration, given as a single dose. The first dose is given before semaglutide treatment and the second dose is given at the end of semaglutide treatment.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Area under the metformin plasma concentration-time curve
Time Frame: During a dosing interval (0-12 hours) after the last of 7 repeated doses of metformin without semaglutide exposure (Day 4) and at semaglutide steady state (Day 104)
During a dosing interval (0-12 hours) after the last of 7 repeated doses of metformin without semaglutide exposure (Day 4) and at semaglutide steady state (Day 104)
Area under the S-warfarin plasma concentration-time curve
Time Frame: From time 0 to 168 hours after a single dose of warfarin without semaglutide exposure (Day 11) and at semaglutide steady state (Day 111)
From time 0 to 168 hours after a single dose of warfarin without semaglutide exposure (Day 11) and at semaglutide steady state (Day 111)
Area under the R-warfarin plasma concentration-time curve
Time Frame: From time 0 to 168 hours after a single dose of warfarin without semaglutide exposure (Day 11) and at semaglutide steady state (Day 111)
From time 0 to 168 hours after a single dose of warfarin without semaglutide exposure (Day 11) and at semaglutide steady state (Day 111)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Maximum observed metformin plasma concentration at steady state
Time Frame: From dosing until 30 hours after the last of 7 repeated doses without semaglutide exposure and at semaglutide steady state (metformin administration on Days 4 and 104)
From dosing until 30 hours after the last of 7 repeated doses without semaglutide exposure and at semaglutide steady state (metformin administration on Days 4 and 104)
Maximum observed S-warfarin plasma concentration after single dose
Time Frame: (0-168 hours) after a single dose of warfarin without semaglutide exposure and at semaglutide steady state (warfarin administrations on Days 11 and 111)
(0-168 hours) after a single dose of warfarin without semaglutide exposure and at semaglutide steady state (warfarin administrations on Days 11 and 111)
Maximum observed R-warfarin plasma concentration after single dose
Time Frame: (0-168 hours) after a single dose of warfarin without semaglutide exposure and at semaglutide steady state (warfarin administrations on Days 11 and 110)

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
