About
The purpose of this study is:
- to assess clinical efficacy of Subetta in the combined treatment of type I diabetes mellitus;
- to assess safety of Subetta in the combined treatment of type I diabetes mellitus.
Full description
Patients with type I diabetes mellitus are included in the trial. It is concerned those patients, who by the time of the trial receive basal bolus insulin therapy of type I diabetes mellitus, including basal insulin (using long acting medications) and prandial insulin (short and ultra short acting medications), and with poor glycemic control (HbA1c=7.0-10.0%). For patients, which will be included in the trial (mainly middle aged patients without severe complications of diabetes), HbA1c>7.0% is the marker showing that optimal individual goal of glycemic control is not achieved.
HbA1c, fasting plasma glucose, microalbuminuria, estimated glomerular filtration rate, ophthalmoscopy, blood pressure measurement, patient self-monitoring of blood glucose, frequency of hypoglycemia, endocrinologist examination were performed within screening period. Patients without severe diabetes complications are randomized in 2 groups.
If a patient meets inclusion criteria and does not show exclusion criteria he/she is randomized in one of 2 groups: Group 1 - patients receiving standard type I diabetes mellitus therapy + Subetta at a dose of 1 tablet 4 times a day; Group 2 - the group receiving standard type I diabetes mellitus therapy + Placebo under the regimen used for Subetta. The invented names of the drugs containing basal and prandial (meal) insulin should be unchanged for each patient during the whole trial.
All patients will receive glucometers and the appropriate glucose test strips, so they could self monitor blood glucose and register this data in their diaries.
The trial duration is 38 weeks; the main stages of the trial are conducted during screening, then in 4 weeks (Visit 2), in 12 weeks (Visit 3), in 24 weeks (Visit 4) and in 36 weeks (Visit 5). In 1 week after randomization and the onset of the trial therapy and between the visits to the study site (on weeks 8±1, 18±1 and 30±1) an investigator collects data on patient's health and complaints (phone visits) to decide whether it is necessary to arrange unplanned visit to the site.
