Detailed Description
Patients with type II diabetes mellitus are included in the trial. It is concerned those patients, who by the time of the trial receive basal insulin with metformin or metformin and sulfonylurea derivatives and with lack of optimal glycemic control (HbA1c>7.0%). 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.
If a patient meets inclusion criteria and does not show exclusion criteria he/she is randomized in one of 2 groups: Group 1 - the group receiving standard type II diabetes mellitus therapy + Subetta at a dose of 1 tablet 4 times a day; Group 2 - the group receiving standard type II diabetes mellitus therapy + Placebo under the regimen used for Subetta. The invented names of the drugs containing basal insulin, metformin and sulfonylurea derivatives used as standard type II diabetes mellitus therapy, 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±1and 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.

Changes in basal insulin dose is based on the mean value of 3 consecutive measuring of level of fasting blood glucose. If value of fasting blood glucose at 7:00 AM on January 21, 2012 - 4.2 mmol/L, at 7:30 AM on January 22, 2012- 5.0 mmol/L, at 7:00 AM on January 23, 2012 4.8 mmol/L, then the mean level of blood glucose =4.7 mmol/L (4.2 +5.0 +4.8 divided by 3). It is not recommended to change the dose. If the mean value of fasting blood glucose is lower than 4.0 mmol/L and a patient shows unreasonable signs or symptoms of hypoglycemia, then dose of basal insulin should be reduced by 2 units. If value of fasting blood glucose for 3 consecutive days was ≥7 mmol/L, then dose of basal insulin should be increased by 2 units and more (depending on individual values). Based on the same values investigator can change dose of per oral blood sugar-lowering drugs. |

Satisfaction of Diabetes Treatment Based on Diabetes Treatment Satisfaction Questionnaire Data
Time Frame: In 36 weeks of the treatment
|
The Diabetes Treatment Satisfaction Questionnaire allows to assess the degree of satisfaction with treatment for diabetes and its complications - retinopathy and nephropathy, how patients' satisfaction and perceived hyper- and hypoglycemia have changed compared to the initial period (before the treatment). The Diabetes Treatment Satisfaction Questionnaire contains six items scored on 7-point scales from +3 (equals "very satisfied") to -3 (equals "very dissatisfied"), with 0 (equals "no change"). These are summed to produce a total Treatment Satisfaction score. Two questions concerning "Perceived Hyperglycaemia" and "Perceived Hypoglycaemia" respectively, are calculated separately. According to these two items, low scores represent good perceived blood glucose control (+3 means "most of the time" of Hyperglycaemia or Hypoglycaemia whereas -3 means "none of the time" of Hyperglycaemia or Hypoglycaemia). |
