Brief Title  ICMJE A Study To Evaluate The Efficacy And Safety Of Ertugliflozin In Participants With Type 2 Diabetes Mellitus And Inadequate Glycemic Control On Metformin Monotherapy (MK-8835-007).
Official Title  ICMJE A Phase 3, Randomized, Double-Blind, Placebo-Controlled, 26-Week Multicenter Study With a 78-Week Extension To Evaluate The Efficacy And Safety Of Ertugliflozin In Subjects With Type 2 Diabetes Mellitus And Inadequate Glycemic Control On Metformin Monotherapy.
Brief Summary This is an efficacy and safety study of ertugliflozin in participants with type 2 diabetes mellitus (T2DM) and inadequate glycemic control on metformin monotherapy. The primary study hypothesis is that at Week 26, the mean reduction from baseline in hemoglobin A1c (HbA1c) for ertugliflozin is greater than that for placebo.
Detailed Description The trial includes a 13-15 week run-in period prior to randomization, and a 26-week, double-blind, placebo-controlled treatment period followed by a 78-week double-blind, extension period.
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 3
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Condition  ICMJE Type 2 Diabetes Mellitus
Intervention  ICMJE
  • Drug: Ertugliflozin 5 mg

    Other Name: MK-8835
  • Drug: Ertugliflozin 15 mg
    Ertugliflozin 15 mg orally (1 ertugliflozin 5 mg tablet and 1 ertugliflozin 10 mg tablet), once daily from Day 1 to Week 104.
    Other Name: MK-8835
  • Drug: Placebo to Ertugliflozin
    Placebo to ertuglioflozin (1 placebo ertugliflozin 5 mg tablet and/or 1 placebo ertugliflozin 10 mg tablet), orally once daily from Day 1 to Week 104.
  • Other: Glimepiride
    Open-label Glimepiride will be used for glycemic rescue therapy (up to a maximum of 6 or 8 mg per day, based on the local label of glimepiride) in the 26-week initial period. Blinded Glimepiride (up to a maximum of 6 or 8 mg per day, based on the local label of glimepiride will be used in the 78-week extension period in participants who were not rescued with open-label glimepiride during the 26-week initial period.

    • GLIMY
  • Drug: Placebo to Glimepiride
    Placebo to glimepiride will be used in the 78-week extension period in participants who were not rescued with open-label glimepiride during the 26-week initial period. Dosing and titration of placebo to glimepiride is at the discretion of the investigator.
  • Biological: Basal Insulin
    Basal insulin will be administered in the initial 26-week period for participants with glucose values exceeding protocol-specified values and for participants requiring rescue therapy in the 78-week extension period. Dosing and titration of basal insulin is at the discretion of the Investigator.

  • Experimental: Ertuglifozin 5 mg
    Ertugliflozin 5 mg orally, once daily from Day 1 to Week 104. Up to 26 weeks, participants meeting glycemic rescue criteria were rescued with open-label glimepiride, and if they met rescue criteria again, and they were on maximal tolerated doses of glimepiride, they received basal insulin. After Week 26, non-rescued participants who had a fasting finger-stick glucose ?110 mg/dL received glimepiride/placebo. If a participant met glycemic rescue criteria after 26 weeks, and they were on maximal tolerated dose of glimepiride, then rescue with basal insulin was initiated.
    Interventions:
    • Drug: Ertugliflozin 5 mg
    • Drug: Placebo to Ertugliflozin
    • Other: Glimepiride
    • Drug: Placebo to Glimepiride
    • Biological: Basal Insulin
    • Drug: Metformin
  • Experimental: Ertugliflozin 15 mg
    Ertugliflozin 15 mg orally, once daily from Day 1 to Week 104. Up to 26 weeks, participants meeting glycemic rescue criteria were rescued with open-label glimepiride, and if they met rescue criteria again, and they were on maximal tolerated doses of glimepiride, they received basal insulin. After Week 26, non-rescued participants who had a fasting finger-stick glucose ?110 mg/dL received glimepiride/placebo. If a participant met glycemic rescue criteria after 26 weeks, and they were on maximal tolerated dose of glimepiride, then rescue with basal insulin was initiated.
    Interventions:
    • Drug: Ertugliflozin 15 mg
    • Other: Glimepiride
    • Drug: Placebo to Glimepiride
    • Biological: Basal Insulin
    • Drug: Metformin
  • Placebo Comparator: Placebo/Glimepiride
    Placebo to ertugliflozin, orally once daily from Day 1 to Week 104. Up to 26 weeks, participants meeting glycemic rescue criteria were rescued with open-label glimepiride, and if they met rescue criteria again, and they were on maximal tolerated doses of glimepiride, they received basal insulin. After Week 26, non-rescued participants who had a fasting finger-stick glucose ?110 mg/dL received blinded glimepiride. If a participant met glycemic rescue criteria after 26 weeks, and they were on maximal tolerated dose of glimepiride, then rescue with basal insulin was initiated.
    Interventions:
    • Drug: Placebo to Ertugliflozin
    • Other: Glimepiride
