Clinical Trial to Evaluate the Safety and Efficacy of the Addition of Sitagliptin in Participants With Type 2 Diabetes Mellitus Receiving Acarbose Monotherapy (MK-0431-130)

19. juli 2018 opdateret af: Merck Sharp & Dohme LLC

A Phase III, Multicenter, Randomized, Placebo-Controlled, Double-Blind Clinical Trial to Evaluate the Safety and Efficacy of the Addition of Sitagliptin in Patients With Type 2 Diabetes Mellitus Who Have Inadequate Glycemic Control on Diet/Exercise Therapy and Acarbose Monotherapy

This study will evaluate whether the addition of sitagliptin reduces hemoglobin A1C (A1C) more than the addition of placebo for participants with type 2 diabetes mellitus (T2DM) on a steady dose of acarbose. The primary hypothesis is that the addition of sitagliptin 100 mg once daily (q.d.) reduces A1C more than the addition of placebo in participants with T2DM with inadequate glycemic control on acarbose monotherapy.

Detaljeret beskrivelse

The study includes an 8-week antihyperglycemic agent (AHA) wash-off period* (which includes a 2-week single-blind placebo run-in period) followed by a 24-week double-blind treatment period. All participants will receive open-label acarbose at a minimum dose of 50 mg three times daily (t.i.d.) during the run-in and treatment periods.

*: Wash-off only applicable to patients who were on acarbose and another AHA.

Intervention / Behandling
Eksperimentel: Sitagliptin
Sitagliptin 100 mg daily (q.d.) + acarbose (continuing the current stable dose of at least 50 mg three times daily [t.i.d.])
Medicin: Sitagliptin phosphate
Sitagliptin, 100 mg tablet once daily, orally for 24 weeks
Andre navne:
  • Januvia
Medicin: Acarbose
Acarbose 50 mg or 100 mg tablet, 3 times daily, orally (continuing on the stable dose established prior to screening) for 24 weeks
Andre navne:
