A Bioequivalence Study of the Fixed Dose Combination Tablets of Canagliflozin and Metformin Extended Release (XR) With Respect to the Individual Components

Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: Canagliflozin, 100 mg; Drug: CANA/MET XR FDC, Formulation 1, 50 mg/500 mg; Drug: CANA/MET XR FDC, Formulation 2, 50 mg/500 mg; Drug: Metformin XR, 500 mg

• Registration Number: NCT02065752
• Lead Sponsor: Janssen Research & Development, LLC

Brief Summary

The purpose of this study is to assess the bioequivalence of the fixed dose combination (two components combined in one tablet) of canagliflozin and metformin extended release (XR) tablet (dose of 2 X 50 mg/500 mg) with respect to the individual components of canagliflozin (1 x 100 mg) and metformin XR tablet (2 x 500 mg) in healthy fed participants.

Detailed Description

This is a randomized (the study medication is assigned by chance), open-label (physicians and participants know the identity of the assigned treatment), single-center, single-dose, 3-treatment, 3-way crossover (the same medications provided to all participants but in different sequence) study of canagliflozin (CANA) and metformin extended release (MET XR) combined in one tablet, in comparison with tablets of individual components. Two Fixed Dose Combinations (FDCs) will be evaluated during the study (two types of tablets). The tablets will be of the same strength (50 mg CANA/500 mg MET XR) and will be compared with the equal doses of the individual drugs: canagliflozin (1 x 100 mg tablet) and metformin XR (2 x 500 mg tablets). Thus, there will be 3 treatment periods in the study: Treatment A: "Reference" treatment of individual components. Treatment B: CANA/MET XR FDC, formulation 1; and Treatment C: CANA/MET XR FDC, formulation 2. Approximately 42 healthy adult participants will be randomly assigned to 1 of 3 treatments groups, and then each group will receive all three treatments in different sequences (3-way crossover). The study will consist of 3 phases: a Screening Phase of approximately 3 weeks (Days -22 to -2), an Open-Label Treatment Phase consisting of 3 single-dose Treatment Periods of 5 days each (Days -1 through 4) separated by a washout of 10 to 14 days between Day 1 of each Treatment Period, and a Follow-up Phase occurring 7 to 10 days after the last study-related procedure on Day 4 of Treatment Period 3. The total duration of the study will be about 70 days for each participant.

Primary Outcome Measures

Name	Time	Method
Plasma concentration of canagliflozin following the single dose of drug administration	Predose, (before tablet intake) up to 72 hours afterdose	Plasma concentrations of canagliflozin are used to evaluate how long canagliflozin stays in the body.
Plasma concentration of metformin following the single dose of drug administration	Predose, up to 36 hours afterdose	Plasma concentrations of metformin are used to evaluate how long it stays in the body.

Secondary Outcome Measures

Name	Time	Method
Percentage of participants with adverse events as a measure of safety and tolerability	Screening, up to Day 10 of the follow-up period
