Primary Outcome Measures:
- Percentage of patients experiencing at least one Hypoglycaemic Event (HE) during the Ramadan fasting period to test superiority [ Time Frame: 1 month ]
Secondary Outcome Measures:
- Percentage of patients without an increase in HbA1c (≤ 0.3%) and with no Hypoglycaemic Events (HEs) [ Time Frame: visit 3 (anytime from week -4 to day -1 before start of Ramadan) to visit 4 (within 4 weeks post-Ramadan fasting period) (minimum 4.5 weeks to maximum 12 weeks) for HbA1c; and during 1 month (Ramadan) for HEs ]
- Change from baseline to endpoint in glycosylated hemoglobin (HbA1c) [ Time Frame: baseline to visit 4 (within 4 weeks post-Ramadan fasting period) (minimum 12.5 weeks to maximum 30 weeks) ]Endpoint is defined as the visit 4 (post-Ramadan) measurement or the last observation obtained during or after Ramadan, prior to or at initiation of rescue medication
- Change from visit 3 (pre-Ramadan visit) to endpoint in glycosylated hemoglobin (HbA1c) [ Time Frame: visit 3 (anytime from week-4 to day-1 before start of Ramadan) to visit 4 (within 4 weeks post-Ramadan fasting period) (minimum 4.5 weeks to maximum 12 weeks) ]Endpoint is defined as the visit 4 (post-Ramadan) measurement or the last observation obtained during or after Ramadan, prior to or at initiation of rescue medication
- Proportion of patients experiencing severe hypoglycemic events during the Ramadan fasting period [ Time Frame: 1 month ]
- mean amplitude of glycemic excursions (MAGE) to measure glucose fluctuations during the day [ Time Frame: 72 hours ]assessed in a selected subgroup of patients
- Treatment adherence during the Ramadan fasting period [ Time Frame: 1 month ]
- Change from visit 3 (pre-Ramadan visit) to endpoint in body weight [ Time Frame: From visit 3 (anytime from week-4 to day-1 before start of Ramadan) to visit 4 (within 4 weeks post-Ramadan fasting period) (minimum 4.5 weeks to maximum 12 weeks) ]Endpoint is defined as the visit 4 (post-Ramadan) measurement or the last observation obtained during or after Ramadan, prior to or at initiation of rescue medication
- Number of unscheduled visit to health care professional [ Time Frame: From visit 3 (anytime from week-4 to day-1 before start of Ramadan) to visit 4 (within 4 weeks post-Ramadan fasting period) (minimum 4.5 weeks to maximum 12 weeks) ]
- Number of days fasted during the Ramadan fasting period [ Time Frame: 1 month ]
- Number of patients with treatment emergent adverse events (AEs), serious AEs, discontinuation due to AEs, deaths or laboratory abnormalities as assessment of safety and tolerability [ Time Frame: Baseline to visit 4 (within 4 weeks post-Ramadan fasting period) (minimum 12.5 weeks to maximum 30 weeks) ]

| Arms | Assigned Interventions |
|---|---|
|
Experimental: Vildagliptin + placebo to Gliclazide
Vildagliptin tablets will be given at 50mg twice daily (bid). Placebo to Gliclazide capsules will be given at an equivalent dose to previous sulfonylurea in multiples of 80mg only (80-320 mg/day). Patients will continue their open-label metformin therapy at dosage between 1500-2500 mg daily.
|
Drug: Vildagliptin
Patients will be instructed to take Vildagliptin tablets at a fixed dose of 50 mg twice daily (double blind therapy)
Other Name: Galvus
Drug: Metformin
Patients in both arms will take Metformin at a dose between 1500mg-2500mg per day, in an open label fashion
Drug: Placebo to Gliclazide
Patients will be instructed to take the Gliclazide matching placebo capsules at an equivalent dose to previous sulfonylurea in multiples of 80mg only (double blind therapy)
|
|
Active Comparator: Gliclazide + placebo to Vildagliptin
Gliclazide capsules will be given in multiples of 80 mg (80-320 mg/day) at a dose equivalent to previous sulfonylurea dose, unless at the investigator's discretion it could be up-titrated to the next available dose (if HbA1c is higher than 7.5%). Placebo to Vildagliptin tablets will be given at 50mg twice daily (bid). Patients will continue their open-label metformin therapy at dosage between 1500-2500 mg daily.

Drug: Gliclazide

Drug: Placebo to Vildagliptin
Patients will be instructed to take Vildagliptin matching placebo tablets at a fixed dose of 50 mg twice daily (double blind therapy).
