Effects of Canagliflozin on C-peptide Clearance in Healthy Volunteers

June 6, 2013 updated by: Janssen-Cilag International NV

A Double-Blind, Randomized, Placebo-Controlled, 2-Way Cross-Over Study to Evaluate the Effect of Single Dose Canagliflozin on Kinetics of C-Peptide in Healthy Subjects

The purpose of this study is to assess whether treatment with a single oral 300 mg dose of canagliflozin alters the kinetics (ie, clearance/removal from body) of serum C-peptide (a protein released from the pancreas during insulin secretion) in healthy adult volunteers.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

This is a double-blind (neither the volunteer nor the study doctor/staff will know the identity of the assigned treatments) study to assess the effect of single oral (taken by mouth) dose of canagliflozin on clearance (removal from the body) of C-peptide in healthy adult volunteers. Healthy volunteers will be randomly (by chance) assigned to receive a single oral dose of canagliflozin followed by a single oral dose of placebo (inactive substance) or a single dose of placebo followed by a single dose of canagliflozin with a period of 7-10 days between treatments. Healthy volunteers will also receive intravenous (i.v.) infusion (injection in the vein) of somatostatin for 4 hours and a single dose i.v. injection of synthetic human C-peptide following administration of canagliflozin or placebo during each treatment period. Somatostatin will suppress the normal secretion of C-peptide, a protein that is released from the pancreas during insulin secretion, so that the human C-peptide administered to volunteers can be accurately measured. The total study duration for each volunteer will be approximately 44 days. During the study, blood and urine samples will be drawn (collected) for clinical laboratory evaluations.

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

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
Measure Description
Time Frame
Change from baseline in C-peptide kinetic parameters
Time Frame: Before and after study drug administration on Day 1 of Treatment Periods 1 and 2

Before and after study drug administration on Day 1 of Treatment Periods 1 and 2

Secondary Outcome Measures

Secondary Outcome Measures
