Brief Summary

The study is to compare the rate and extent of absorption of a generic formulation with that of a reference for mulation when given as equal labeled dose. The study will be randomized, open-label, single dose, two way crossover design with two-period, two-treatment and two-sequence under fasting condition and at least 14 days washout period between the doses.

Detailed Description

This protocol describes an open labelled, single-dose, randomized, two-period, two-treatment, two-sequence crossover study to investigate the bioequivalence of two formulations of Vildagliptin and Metformin tablets 50/1000 mg manufactured by Mylan Laboratories Limited, India to GALVUS MET (50mg/1000 mg) tablets manufactured by NOVARTIS PHARMA PRODUKTIONS GmbH, Germany.

Single-dose fed pharmacokinetics will be characterized in 48 healthy, adult volunteers, for a total of 48 healthy adult subjects.

Approximately eight milliliter (1 × 8 mL) blood samples will be collected in K3 EDTA tubes at pre-dose and the following times after dosing: at 0.25, 0.50, 0.75, 1.00, 1.50, 2.00, 2.50, 3.00, 3.50, 4.00, 4.50, 5.00, 5.50, 6.00, 6.50, 7.00, 8.00, 9.00, 10.00, 12.00, 16.00, 24.00 and 36.00 hours.

The collected blood samples will be transferred into centrifugation room at controlled temperature (2-8°C) and start centrifuged at 4±2°C within 2 hours after blood sample collection. Up to four (4) aliquots of plasma will be added in four pre-labeled cryovials for approximately 1 mL per each cryovial. Two aliquots for analyze vildagliptin and two aliquotes for analyze metformin. Cryovials containing plasma sample will be transferred to deep freezer in controlled temperature (2-8 °C) and will be stored at -70±10 °C.

For the determination of the pharmacokinetic disposition of the formulations, there will be a total of 48 blood samples involving a total of 385 mL (including 10 mL for screening and 7 mL for post-study safety monitoring) of blood collected for pharmacokinetic analysis from each subject who provid their complete all blood collections in the study. There will be at least 7 days between dosing times for the treatment periods.

The bioequivalence of Vildagliptin and Metformin tablets 50/1000 mg manufactured by Mylan Laboratories Limited, India to GALVUS MET (50mg/1000 mg) tablets manufactured by NOVARTIS PHARMA PRODUKTIONS GmbH, Germany will be assessed by a statistical comparison of various pharmacokinetic parameters derived from the plasma concentration-time curves of Vildagliptin and Metformin.
