Evaluation of the Impact of Intensive Short-Term Drug Therapy in Patients With Type 2 Diabetes Mellitus

Evaluation of the Impact of Intensive Short-Term Drug Therapy in Patients With Type 2 Diabetes Mellitus

Pilot Study for Evaluation of the Impact of Intensive Short-Term Drug Therapy on Beta-Cell Function and Insulin Resistance in Patients With Type 2 Diabetes Mellitus

This phase IV study is a prospective open-label multi-center study to investigate the effect of a temporary individualized poly-pharmaceutical De-escalation treatment with the target to regenerate ß-cell function over 12 weeks on the disease stage and glycemic control in patients with type 2 diabetes. This is an uncontrolled pilot study to collect data for later confirmatory trials.

During the screening visit the patient will arrive at the study site and written informed consent will be obtained by the investigator. Inclusion and exclusion criteria will be controlled and blood will be drawn for HbA1c, the efficacy and the safety parameters. A POCT pregnancy test will be conducted in women of childbearing age. Patient demographics and history will be collect and a physical examination will be performed. The patient will complete a QoL questionnaire and will receive training about the de-escalation therapy approach. After all necessary biomarker results of the screening visit are accessible for the selection of the De-escalation treatment the treatment initiation visit will be performed. During this visit the investigator will use these results to determine a most optimal personalized treatment combination for regeneration of the pancreatic ß-cells within the next three months. An ECG will be recorded and the patient will be informed about his/her personalized treatment and its execution. The patient will receive the drugs in the volume required until the next visit. During the next two visits the patient will arrive at the investigational site at the agreed time-point and information regarding potential adverse events will be collected. Vital signs will be measured, and blood will be drawn for assessment of the efficacy parameters. Information about hypoglycaemia will be collected, and the patient will receive drug supply that lasts until the next visit. The patient will be instructed to stop the anti-diabetic medication 3 days before the next visit. For the final visit (visit 5) the patient will arrive at the investigational site after an overnight fast and information regarding potential adverse events and hypoglycaemic events will be collected. Vital signs will be measured, and blood will be drawn for assessment of the efficacy parameters. An oral glucose challenge with 75 g of glucose will be conducted with blood draws for assessment of glucose and other biomarkers at time-points 0, 1h and 2h. The investigator will give a recommendation for the consecutive follow-up treatment requirements based on the results of the glucose challenge test. The patient will complete a QoL questionnaire (DTSQ) and this concludes study participation for the patient.

All employed drugs are approved in the US for treatment of type 2 diabetes and are used within their label. There will be defined individual treatment drug combinations at an earlier stage of diabetes as in standard treatment. The DET combination will be composed out of one each or more of the drugs and interventions listed below. A. Relieve for the insulin-producing ß-cells insulin glargine (6 to 20 U at bedtime) insulin degludec (5 to 15 U at bedtime) B. Reduction of hormonal visceral lipid tissue activity/chronic inflammation Weight loss liraglutide (0.6 mg/day) exenatide (15 µg/day) C. Treatment of metabolic and vascular insulin resistance Pioglitazone (30 mg) D. Treatment of glucose toxicity Empagliflozin (SGLT-II inhibitor; 10 mg) Dapagliflozin (SGLTII-Inhibitor, 10 mg) Canagliflozin (SGLT-II inhibitor, 100 mg) Metformin (inhibition of hepatic glucose production, 500 mg) To avoid hypos, all drugs are initially given in the lowest possible dose.
