NCT01099618

Brief Summary

The study intends on enrolling 48 subjects with diabetes. Diabetic subjects that no longer need insulin will be randomly placed (like the flip of a coin) on a diabetes pill called metformin, a diabetes pill called sitagliptin or a placebo pill (a pill without active medication). Subjects on pills will be followed for 3½ years and undergo blood tests at specified intervals to assess their ability to make insulin. These studies will allow a better understanding of the factors that lead to high blood sugar in patients with ketosis-prone diabetes mellitus (KPDM) and direct the best diabetes treatment for this patient population. Hypothesis: Metformin therapy or sitagliptin therapy compared to placebo, will improve β-cell function, insulin sensitivity, and allow for a longer period of time prior to encountering an insulin-deficient relapse after discontinuation of insulin therapy.

Outcome Measures

Primary Outcomes (1)

  • Length of Remission

    For those patients that are able to discontinue insulin therapy at or \<12 weeks, how long were they able to well controlled with an A1c \<7% on the agent that they were randomized to.

    3 years

Study Arms (3)

Metformin

ACTIVE COMPARATOR

All newly diagnosed subjects with KPDM that are able to discontinue insulin after 12 weeks or less will be randomized in double-blind fashion to receive either metformin 1000mg, sitagliptin 100mg or placebo once daily. Subjects that do not achieve remission will continue to receive insulin therapy and will discontinue the protocol. A total of 48 obese subjects with DKA (N=24) and obese subjects with hyperglycemia without ketoacidosis (n=24) will be equally randomized to receive metformin (MET) 1000 mg (n=16), sitagliptin (SIT) 100mg (n=16) or placebo (n=16).

Drug: metformin

Sitagliptin

ACTIVE COMPARATOR

All newly diagnosed subjects with KPDM that are able to discontinue insulin after 12 weeks or less will be randomized in double-blind fashion to receive either metformin 1000 mg, sitagliptin 100mg or placebo once daily. Subjects that do not achieve remission will continue to receive insulin therapy and will discontinue the protocol. A total of 48 obese subjects with DKA (N=24) and obese subjects with hyperglycemia without ketoacidosis (n=24) will be equally randomized to receive metformin (MET) 1000 mg (n=16), sitagliptin (SIT) 100mg (n=16) or placebo (n=16).

Drug: Sitagliptin

Placebo

PLACEBO COMPARATOR

All newly diagnosed subjects with KPDM that are able to discontinue insulin after 12 weeks or less will be randomized in double-blind fashion to receive either metformin 1000 mg, sitagliptin 100mg or placebo once daily. Subjects that do not achieve remission will continue to receive insulin therapy and will discontinue the protocol. A total of 48 obese subjects with DKA (N=24) and obese subjects with hyperglycemia without ketoacidosis (n=24) will be equally randomized to receive metformin (MET) 1000 mg(n=16), sitagliptin (SIT) 100mg (n=16) or placebo (n=16).

Drug: placebo

Interventions

The study subject will receive metformin (MET) 1000 mg tablet once a day as long as the patient maintains near-normoglycemic remission (BG \< 130mg/dL and A1c \<7%) during the 3-year follow-up period.

Also known as: Glucophage
Metformin

The study subject will receive a placebo tablet once a day as long as the patient maintains near-normoglycemic remission (BG \< 130mg/dL and A1c \<7%) during the 3-year follow-up period.

Placebo

The study subject will receive a sitagliptin 100mg once a day as long as the patient maintains near-normoglycemic remission (BG \< 130mg/dL and A1c \<7%) during the 3-year follow-up period.

Also known as: Januvia
Sitagliptin
