Please assess the completion status of the following clinical trial:

Trial Title: Ketosis-Prone Diabetes Mellitus (KPDM): Metformin Versus Sitagliptin Treatment

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: TRIPLE
- Phase: PHASE4
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~1. All newly diagnosed overweight/obese (BMI \>/=28 kg/m2) African-American patients with new-onset DKA and/or severe hyperglycemia and without apparent precipitating cause will be considered for inclusion into the study. The diagnosis of DKA will be established by standard criteria (blood glucose \> 250 mg/dL, pH \< 7.3, HCO3 \< 18 mmol/L, increased anion gap).~2. The hyperglycemic group will include patients with an admission plasma glucose \> 400 mg/dL but without the presence of metabolic acidosis or ketosis.~Exclusion Criteria:~1. significant medical or surgical illness, including but not limited to myocardial ischemia, congestive heart failure, chronic renal insufficiency, liver failure, and infectious processes;~2. recognized or suspected endocrine disorders associated with increased insulin resistance, such as hypercortisolism, acromegaly, or hyperthyroidism;~3. bleeding disorders, thrombocytopenia, or abnormalities in coagulation studies;~4. pregnancy,~5. have an allergy to any component of metformin or sitagliptin.

Study Arms:
- Metformin (Type: 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).
- Sitagliptin (Type: 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).
- Placebo (Type: 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).
