Primary Outcome Measures:
  • Safety and Tolerability of Sitagliptin After 4 Weeks of Treatment [ Time Frame: 4 weeks ]
    Safety & tolerability were measured in terms of the # of participants with >=1 adverse event (AE), >=1 drug-related AE, >=1 serious AE (SAE), or discontinued treatment due to an AE. SAEs included events occurring after initiation of glycemic rescue therapy. AE is defined as any unfavorable/unintended change in structure, function, or chemistry of the body temporally associated with the use of SPONSOR's product. SAE is defined as any AE that results in death, is life-threatening, an overdose, causes or prolongs in-patient hospitalization, or considered medically significant by the investigator.

Secondary Outcome Measures:
  • Change From Baseline in Fasting Plasma Glucose at Week 4 [ Time Frame: Baseline and Week 4 ]
    Calculated as the mean change from baseline in fasting plasma glucose at Week 4.

Enrollment: 30
