Condition(s) targeted: Diabetes Mellitus Type 2; Severe Hyperglycemia - Blood Glucose Level >300mg/dl.

Intervention: Glipizide XL (Drug); Saxagliptin + Metformin XR (Drug); Metformin XR (Drug)

Phase: Phase 4

Summary

Saxagliptin + Metformin XR (S+M) will be effective in stabilizing blood glucose (BG) levels in patients with newly diagnosed type 2 diabetes (T2DM) with severe hyperglycemia (BG levels 300 to 450 mg/dl) and glucose toxicity and with no criteria for inpatient admission or occurrence of severe hypoglycemia compared to glipizide XL. The study may provide preliminary evidence to support the role of S+M as a bridging, stabilizing and safe therapy in patients with severe hyperglycemia

Clinical Details

Official title: A Pilot Study of Outpatient Discharge Therapy With Saxagliptin + Metformin XR or Sulphonylurea for Recently Diagnosed Type 2 Diabetes Presenting With Severe Hyperglycemia

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: The proportion of responders in each arm. Responder: FBG 70-300 and/or PPBG <400 mg/dl (week1-6), FBG 70-250 and/or PPBG <300 mg/dl (week 7-12) and without metabolic exclusion criteria, repeat ED visits, hospitalization or significant hypoglycemia.

Secondary outcome:

Proportion of patients achieving FBG goal of 70-130 mg/dl at 12 weeks in the 2 treatment arms

Percentage of patients with symptomatic hypoglycemia

To measure percentage compliance with medication in the two treatment arms.

The number of fold increase in beta cell function in the 2 arms.

Detailed description: There is very little information regarding diabetes discharge regimens for patients with recently diagnosed diabetes (<1 year duration) who present with severe hyperglycemia (blood glucose 300-450 mg/dl) to the ED or other clinical settings and who do not need to be admitted. A combination of Saxagliptin+Metformin XR, could be a potential drug combination to be tested as an initial treatment in these circumstances compared to Glipizide XL which was shown to be effective in our previous study. We expect Saxagliptin to improve beta cell function and decrease glucagon levels as was shown for the DPP-IV class medications and in turn improve blood glucose levels, while Metformin XR may reduce insulin resistance and hepatic glucose output. Such discharge therapy may help to prevent deterioration into acute metabolic complications (DKA or hyperosmolar states) and avoid hospitalization. A high proportion of patients may achieve glycemic targets without significant hypoglycemia as measured by self glucose monitoring and objectively by continuous glucose monitoring system (CGMS). Such an easy regimen may safely bridge the time gap until patients will be seen by their providers.
