E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate in Muslim patients with T2DM who plan to fast during the
Ramadan fasting period:
The proportion of patients with at least one HE (Hypoglycaemic event) is
lower in the vildagliptin plus metformin arm compared to the gliclazide
plus metformin arm during the Ramadan fasting period. |
|
E.2.2 | Secondary objectives of the trial |
1. Evaluate the proportion of patients with an increase in HbA1c
(<=0.3%), taken at visit 3 to the last visit with no HEs during Ramadan
in the vildagliptin plus metformin (A) arm versus the gliclazide plus
metformin arm (B).
2. Evaluate the change in HbA1C from randomisation to the last visit, in
the A arm versus B arm
3. Evaluate HbA1c change, taken at Visit 3 to study end.
4. Evaluate the incidence of severe HEs during Ramadan
5. Evaluate, in a selected sub-group (approx 25 patients/arm), 72h
continuous subcutaneous glucose monitoring (CGM, masked to patients)
comparing glucose fluctuation during the first 10 days of Ramadan.
6. Evaluate the treatment adherence during Ramadan
7. Evaluate the body weight change taken at Visit 3 to the last visit
8. Evaluate the unscheduled visits to the HCP, at Visit 3 to the last visit
9. Evaluate the number of days fasted during Ramadan
10. Safety and tolerability |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Substudy on evaluation of Glucose fluctuations through Continuous Glucose Monitoring (CGM):
In a subset of about 50 patients (approximately 25 subjects in each arm), 72h continuous glucose monitoring (CGM) will be performed during the first 10 days of Ramadan fasting period at experienced centres.
The CGM data will be downloaded to a computer for evaluation of glucose profiles and
fluctuation. The mean amplitude of glycemic excursions (MAGE) will be used for assessing glucose fluctuations during the day. The MAGE during the day for each patient will be summarised descriptively (with mean, standard deviation, median, minimum and maximum) by treatment and day. A figure indicating the mean MAGE over time (in days) will be shown.
