Clinical Trial Summary

This study was designed to compare the bioavailability of the Test Product Metformin 500mg Prolonged Release Tablets (JSC Farmak, Ukraine) and Reference Product Glucophage® XR 500 mg Prolonged Release Tablets (Merck Serono Ltd, UK) in healthy male and female volunteers under fasting conditions.

Description:

An Open, Comparative, Randomized, Crossover Clinical Trial to Evaluate the Bioequivalence of Single Doses of Test Product Metformin 500mg Prolonged Release Tablets (JSC Farmak, Ukraine) and Reference Product Glucophage® XR 500 mg Prolonged Release Tablets (Merck Serono Ltd, UK) in Healthy, Adult Male and Female Subjects under Fasting Conditions.

During each period 21 blood samples were taken: prior to dosing (-1.0) and 1.0, 2.0, 3.0, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 10.0, 12.0, 16.0, 24.0, 32.0 and 36.0 hours after Investigational Medicinal Product (IMP) administration.

• Glucose level out of the limit 3.3 mmol/L - 5.5 mmol/Lat screening, as determined by screening clinical laboratory evaluations.

• Previous liver disease or clinically significant elevations in serum transaminases at the screening.

• Acute or chronic diseases and/or clinical finding which may interfere with the aims of the study or with the drug's safety, tolerability, bioavailability and/or pharmacokinetics of the IMP.

• History of kidney disease and with impaired renal function.

• History of severe allergy or allergic reactions to the study IMP, its excipients or related drugs.

• Clinically significant illness within 28 days before the first dosing, including major surgery.

• Any significant clinical abnormality including Hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV), and / or (human immunodeficiency virus) HIV. (On screening).

• Positive result of blood pregnancy test at screening or positive urine pregnancy test at check-in or breast-feeding or lack of results of pregnancy test.

• Positive results of drugs of abuse in urine at screening and at check-in.

• Positive result of alcohol breath test at screening and at check-in.

• Positive result of urine cotinine test at screening and at check-in.

• Serious mental disease and/or inability to cooperate with clinical team.

• Sitting blood pressure after a minimum of 5 minutes of rest is out of the range of 90-140 mmHg for systolic blood pressure (BP) and/or 60-90 mmHg for diastolic BP and/or heart rate out of the range of 50-100 bpm during the screening procedure.

• Body ear temperature is out of the range of 35.7 - 37.3°C at screening and at check-in.

• Orthostatic hypotension during the screening procedure.

• Drug, alcohol (of = 40 g per day pure ethanol), solvents or caffeine abuse.

• Use of organ-toxic drugs or systemic drugs known to substantially alter liver metabolism within 90 days before the first dosing.

• Use of any prescription medication for a period of 28 days before the first dosing.

• Use of any OTC (over-the-counter) medication including vitamins, herbal medications and food supplements less than 14 days before the first dosing.

• Getting a tattoo, body piercing or any cosmetic treatment involving skin piercing within 90 days before the screening unless evaluated by Investigator as non-significant for inclusion in the study.

• Donation or loss of at least 500 mL of blood within 90 days or donation of plasma or platelets within 14 days before the first dosing.
