The purpose of this study is to assess, after single oral administration under fed conditions, the bioequivalence between the two batches of the same glimepiride/metformin hydrochloride (HCl) 2 mg/1000 mg fixed dose combination (FDC) tablets (immediate release combination tablet Amaryl® M IR 2/1000) manufactured in India and in Turkey.

An open-label, randomized, two-treatment crossover bioequivalence study comparing two batches of the same fixed dose combinations Amaryl® M IR 2/1000 (glimepiride/metformin hydrochloride immediate release combination tablet) in fed conditions in healthy male and/or female subjects.

Primary Objective To assess, after single oral administration under fed conditions, the bioequivalence between the two batches of the same glimepiride/metformin hydrochloride (HCl) 2 mg/1000 mg fixed dose combination (FDC) tablets (immediate release combination tablet Amaryl® M IR 2/1000) manufactured in India and in Turkey.

Secondary Objective(s) To assess the safety (including hypoglycemic events) of the two FDC (Amaryl® M IR 2/1000) tablets.

Up to 50 healthy subjects are to be enrolled to have 46 subjects available for the final pharmacokinetic evaluation.

Study treatment:

In each period A single dose of glimepiride/metformin HCl 2mg/1000 mg FDC (manufactured in India) Or single dose of glimepiride/metformin HCl 2mg/1000 mg FDC (manufactured in Turkey) will be administered after breakfast.

PRIMARY AND SECONDARY ENDPOINT(S)

Primary Endpoint:

Glimepiride and metformin: Cmax and AUClast

Secondary Endpoint(s):

Glimepiride and metformin: AUC0-inf, tlag, tmax and t1/2z Safety

DURATION OF STUDY (per patient) Screening : up to 15 days Treatments periods: 4 days each including treatment day Wash-out period: 4 to 7 days Follow-up: 4 to 7 days Total study duration: 37 days

Inclusion Criteria:

- Demography

1. Male subjects and female subjects of non-childbearing potential (post- menopausal or sterilized) aged 18 to 50 years inclusive.

2. Body weight between 50.0 and 95.0 kg, inclusive, if male, and between 40.0 and 85.0 kg, inclusive, if female, body mass index between 18.0 and 30.0 kg/m2, inclusive.

   • Health status

3. Certified as healthy by a comprehensive clinical assessment (detailed medical history (hypo-, hypertension, allergy, other diseases, major surgery, micturition, defecation, sleep, illness within the last 3 weeks prior start of the trial, registration of life style and habits (consumption of alcohol, nicotine, coffee, tea, coke, special diet, drug abuse) and complete physical examination (general state and abnormal findings per system: endocrine/metabolic, allergies, drug sensitivities, head, neck, eyes, ears, nose, throat, cardiovascular, respiratory, gastrointestinal, hepatic/biliary, urogenital, musculoskeletal, Iymph nodes, skin, and neurological/psychiatric).

4. Normal vital signs after 10 minutes resting in supine position:

   • 90 mmHg < systolic blood pressure (SBP) <140 mmHg
   • 45 mmHg < diastolic blood pressure (DBP) <90 mmHg
   • 40 bpm < heart rate (HR) <100 bpm

5. Normal standard 12-lead electrocardiogram (ECG) after 10 minutes resting in supine position in the following ranges; 120 ms<PR<220 ms, QRS<120 ms, QTc≤430 ms if male, ≤450 ms if female and normal ECG tracing unless the Investigator considers an ECG tracing abnormality to be not clinically relevant.

6. Laboratory parameters within the normal range (or defined screening threshold for the Investigator site), unless the Investigator considers an abnormality to be clinically irrelevant for healthy subjects; however blood/serum examination creatinine, alkaline phosphatase, hepatic enzymes (aspartate aminotransferase, alanine aminotransferase), and total bilirubin (unless the subject has documented Gilbert syndrome) should not exceed the upper laboratory norm. For female of non-childbearing potential, sterilized at least 3 months earlier or postmenopausal i.e. artificial or natural menopause for more than 2 years with plasma FSH level > 30 UI/L.
