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.

|---|---|---|---|
| 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). |
