The Bioequivalence Study of Fixed-dose Combination of Vildagliptin and Metformin HCI 50/1000 mg FCT Under Fed Conditions

A Single Dose, Randomized, Open-label, Two-way Crossover Bioequivalence Study of Fixed-dose Combination of Vildagliptin and Metformin HCI 50/1000 mg FCT and Reference Product (Galvus Met®) in Healthy Thai Volunteers Under Fed Conditions

To determine and compare the rate and extent of absorption of a test formulation with that of a reference innovator formulation when given as equal labeled dose in healthy subjects under fed conditions

Study Overview

• Status: Not yet recruiting
• Conditions: Healthy Volunteer
• Intervention / Treatment: Drug: Vildagliptin and Metformin Hydrochloride 50mg 1000 mg Film-coated Tablets

Detailed Description

This study is conducted to investigate bioequivalence information which is required to ensure therapeutic equivalence of a test product and a reference product as well as to be considered as one aspect of product quality. Bioequivalence is defined as the absence of a significant difference in the rate and extent to which the active ingredient or active moiety in pharmaceutical equivalents or pharmaceutical alternatives becomes available at the site of drug action when administered at the same molar dose under similar conditions in an appropriately designed study.

The manufacturer needs to formulate a generic Fixed-dose Combination of Vildagliptin and Metformin HCI 50/1000 mg FCT. This study has been planned to evaluate the pharmacokinetics of this formulation and determine its bioequivalence with the reference product, Galvus Met®, at the same dose.

Female subjects abstain from either hormonal methods of contraception (including oral or transdermal contraceptives, injectable progesterone, progestin subdermal implants, progesterone-releasing IUDs, postcoital contraceptive methods) or hormone replacement therapy for at least 28 days prior to check-in in Period 1. Injectable contraceptives e.g. Depo-Provera® will be discontinued at least 6 months prior to check-in in Period 1.

Female subjects of non-childbearing potential must meet at least one of the following criteria prior to check-in in Period 1:

   • Postmenopausal for at least 1 year

History or evidence of clinically significant renal, hepatic, gastrointestinal, hematological (e.g. anemia), endocrine (e.g. hypo-/hyperthyroid, diabetes), pulmonary or respiratory (e.g. asthma), cardiovascular (e.g. hypo-/hypertension), psychiatric, neurologic (e.g. seizures), allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing) or any significant ongoing chronic medical illness

History or evidence of drug addict or investigation with urine sample shows a positive test for drug of abuse (morphine, marijuana or methamphetamine) 16.12-lead ECG demonstrating QTc >450 msec, a QRS interval >120 msec or with an abnormality considered clinically significant at screening. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG will be repeated two more times and the average of the three QTc or QRS values will be used to determine the subject's eligibility.
