NCT03714594

Brief Summary

A phase IV, randomized, double-blind, single center pilot study in subjects with type 2 diabetes poorly controlled with metformin therapy will be randomized to receive, on top of metformin: saxagliptin (5 mg/day) and dapagliflozin (10 mg/day) (Group 1);saxagliptin (5 mg/day) and placebo (Group 2); dapagliflozin (10 mg/day) and placebo (Group 3) for 4 weeks.

Outcome Measures

Primary Outcomes (1)

  • Glucose Metabolism

    To determine the effect of the combination of dapagliflozin (a SGLT2-inhibitor) and saxagliptin (a DPP-4 inhibitor) on pancreatic hormones secretion and endogenous glucose production in Type 2 diabetic subjects through comparison of the effects of co-administration of Saxagliptin and Dapagliflozin vs. Saxagliptin or Dapagliflozin alone.

    from first day

Study Arms (3)

Dapagliflozin 10mg

ACTIVE COMPARATOR

Dapagliflozin inhibits SGLT2 promoting the excretion of glucose in the urine,and lowers the plasma glucose concentration. This class of drugs has been shown to effectively reduce the HbA1c at all stages of T2DM and can be used in combination of all other anti-diabetic agents including insulin.

Drug: Dapagliflozin 10mg

Saxagliptin 5mg

ACTIVE COMPARATOR

Saxagliptin is a DPP4 inhibitor.In patients with type 2 diabetes,administration of saxagliptin led to inhibition of DPP4 enzyme activity.After an oral glucose load,this DPP4 inhibition resulted in a increase in circulating levels of active incretin hormones include GLP-1 and GIP, decreased glucagon concentrations and increased glucose-dependent beta-cell responsiveness,which resulted in higher insulin and C-peptide concentrations.The rise in insulin from pancreatic beta-cells and the decrease in glucagon from pancreatic alpha-cells were associated with lower fasting glucose concentrations and reduced glucose excursion following an oral glucose load or a meal.Saxagliptin improves glycaemic control by reducing fasting and postprandial glucose concentrations in patients with type 2 diabetes.

Drug: Dapagliflozin 10mgDrug: Saxagliptin 5mg

Saxagliptin 5 mg + dapagliflozin 10 mg

ACTIVE COMPARATOR

Please see Arm 1 and 2

Drug: Saxagliptin 5mg + Dapagliflozin 10 mg

Interventions

Dapagliflozin inhibits subtype 2 of the sodium-glucose transport proteins (SGLT2) which are responsible for at least 90% of the glucose reabsorption in the kidney. Blocking this transporter mechanism causes blood glucose to be eliminated through the urine.\[

Also known as: forxiga
Dapagliflozin 10mgSaxagliptin 5mg

Inhibits DPP-4 and slows inactivation of incretin hormones, thereby increasing blood concentrations and reducing fasting and postprandial glucose concentrations in a glucose-dependent manner in patients with type 2 diabetes mellitus
