Summary

The purpose of the study is to assess the effect of the addition of sitagliptin to metformin with or without a sulfonylurea compared with the addition of dapagliflozin to metformin with or without a sulfonylurea on hemoglobin A1c (A1C) over 24 weeks of treatment as well as the overall safety and tolerability of sitagliptin in comparison to that of dapagliflozin after 24 weeks of treatment. The primary hypothesis is that the change from baseline in A1C in participants treated with the addition of sitagliptin is non-inferior compared to that in participants treated with the addition of dapagliflozin after 24 weeks of treatment.

Conditions

Interventions

DRUG

Sitagliptin

Sitagliptin 100 mg oral tablet

DRUG

Dapagliflozin

Dapagliflozin 5 mg or 10 mg oral capsule. Up-titration to dapagliflozin 10 mg daily may be delayed if participant is unable to tolerate up-titration in the opinion of the investigator. Dapagliflozin 10 mg daily may be down-titrated to dapagliflozin 5 mg daily if participant is unable to tolerate the higher dose in the opinion of the investigator.

DRUG

Metformin

This medication is a standard-of-care medication and is administered in an open-label fashion. Supply of background metformin oral tablet(s) (at least 1500 mg daily) will be the responsibility of the participant throughout the duration of the study.

DRUG

Matching placebo to sitagliptin

Matching placebo to sitagliptin 100 mg oral tablet

DRUG

Matching placebo to dapagliflozin

Matching placebo to dapagliflozin 5 mg or 10 mg oral capsule. Up-titration to matching placebo to dapagliflozin 10 mg daily may be delayed if participant is unable to tolerate up-titration in the opinion of the investigator. Matching placebo to dapagliflozin 10 mg daily may be down-titrated to matching placebo to dapagliflozin 5 mg daily if participant is unable to tolerate the higher dose in the opinion of the investigator.

DRUG

Sulfonylurea

This medication is a standard-of-care medication and is administered in an open-label fashion. The dose of the sulfonylurea agent will be required to be at least 50% of maximum labeled dose, consistent with near maximum efficacy of the sulfonylurea agent.
