Brief Summary:
The purpose of this study is to evaluate the efficacy of 2 doses of TAK-875 (25 mg and 50 mg), once daily (QD), plus metformin compared to placebo plus metformin and sitagliptin plus metformin on lowering blood sugar.

Condition or disease Intervention/treatment Phase
Glycemic Control Drug: Fasiglifam (TAK-875) Drug: Sitagliptin Drug: Placebo Phase 3

Detailed Description:

TAK-875 is being developed at Takeda Development Center, Inc. as an adjunct to diet and exercise to improve glycemic control in participants with Type 2 Diabetes Mellitus (T2DM) whose blood glucose level is inadequately controlled with metformin.

This study will evaluate the efficacy of TAK-875 (25 mg and 50 mg) plus metformin compared to placebo plus metformin and sitagliptin plus metformin on glycemic control as measured by change from baseline in glycosylated hemoglobin (HbA1c) over a 24-week Treatment Period. Participants completing the 24-week Treatment Period may enter an optional 80-week extension period for a total of 104 weeks of treatment.

Due to concerns about potential liver safety, on balance, the benefits of treating patients with fasiglifam (TAK-875) do not outweigh the potential risks.

For this reason, Takeda has decided voluntarily to terminate the development activities for fasiglifam.

Primary Outcome Measures :
  1. Change From Baseline in Glycosylated Hemoglobin (HbA1c) [ Time Frame: Baseline and Week 24 ]
    The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at Week 24 relative to Baseline. A Mixed Model Repeated Measures (MMRM) model was used for analysis with treatment, country, schedule, visit and visit by treatment interaction as fixed factors and with Baseline value and Baseline value by visit interaction as covariates with an unstructured covariance structure.


Secondary Outcome Measures :
  1. Incidence of HbA1c <7% [ Time Frame: 24 Weeks ]
    Incidence (percentage) of participants with glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) less than 7% at Week 24.

  2. Change From Baseline in Fasting Plasma Glucose (FPG) [ Time Frame: Baseline and Week 24 ]
    The change between FPG collected at week 24 relative to Baseline. A MMRM model was used for analysis with treatment, country, schedule, visit and visit by treatment interaction as fixed factors and with Baseline value and Baseline value by visit interaction as covariates with an unstructured covariance structure.

Criteria

Inclusion Criteria:

  1. The participant is male or female and 18 years of age or older with a historical diagnosis of type II diabetes mellitus.
  2. The participant meets one of the following criteria:

    1. The participant has an HbA1c level ≥7.5 and <10.5%, and has been on a stable daily dose of ≥1500 mg (or documented maximum tolerated dose [MTD]) of metformin for at least 2 months prior to Screening. This participant will immediately enter the Placebo Run-in Period according to Study Schedule A, or;
    2. The participant has an HbA1c level ≥7.5 and <10.5%, and has been on a stable daily dose of <1500 mg of metformin without documented MTD for at least 2 months prior to Screening. After completing the Screening Visit, this participant will have their metformin dose immediately increased to ≥1500 mg (or MTD) for an 8-week Titration Period according to Study Schedule B. Following this 8-week period, the participant must qualify for entry into the Placebo Run-in Period by completing the Week -3 procedures including having an HbA1c level ≥7.5 and <10.5%.

  4. The participant has a body mass index (BMI) ≤45 kg/m² at Screening.
  5. Participants regularly using other, non-excluded medications, must be on a stable dose for at least 4 weeks prior to Screening. However, PRN (as needed) use of prescription or over-the-counter medications is allowed at the discretion of the investigator.
  6. The participant is able and willing to monitor glucose with a home glucose monitor and consistently record his or her own blood glucose concentrations and complete subject diaries.

Exclusion Criteria:

  1. The participant donated or received any blood products within 12 weeks prior to Screening or is planning to donate blood during the study.
