Brief Summary:
The purpose of this study is to evaluate the effect of TAK-875 (fasiglifam) in combination with sitagliptin on glycemic control in adults with type 2 diabetes.

Condition or disease Intervention/treatment Phase
Diabetes Drug: Placebo Drug: TAK-875 Phase 3

Detailed Description:

The drug being tested in this study is called TAK-875 (fasiglifam). Fasiglifam is being tested to treat people who have type 2 diabetes mellitus and are currently taking sitagliptin (with or without metformin). This study will evaluate glycemic control in people who take fasiglifam plus sitagliptin compared with placebo plus sitagliptin.

The study will enroll approximately 390 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the three treatment groups-which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need; all participants will be on 100 mg sitagliptin and may or may not be on metformin background treatment):

  • fasiglifam 25 mg
  • fasiglifam 50 mg
  • Placebo (dummy inactive pill) - this is a tablet that looks like the study drug but has no active ingredient All participants will be asked to take one tablet at the same time each day throughout the study.

This multi-centre trial will be conducted in North America and Latin America. The overall time to participate in this study is approximately 38 weeks. Participants will make 15 visits to the clinic.

Due to potential concerns about 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 HbA1c at Week 24 [ Time Frame: Baseline and Week 24 ]
    The change in the value of HbA1c (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.

Secondary Outcome Measures :
  1. Percentage of Participants With HbA1c <7% [ Time Frame: Week 24 ]
  2. Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 [ Time Frame: Baseline and Week 24 ]
    The change between the fasting plasma glucose values collected at Week 24 relative to baseline.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. In the opinion of the investigator, the participant is capable of understanding and complying with protocol requirements.
  2. The participant or, when applicable, the participant's legally acceptable representative signs and dates a written, informed consent form and any required privacy authorization prior to the initiation of any study procedures.
  3. The participant is male or female and aged 18 years or older with a historical diagnosis of T2DM.
  4. The participant meets one of the following criteria:

    • The participant has an HbA1c between 7.5% and 10.5%, inclusive and has been taking a stable dose of sitagliptin 100 mg for at least 8 weeks, with or without metformin, prior to the Screening Visit. A participant who is taking metformin must have received a stable daily dose (≥1500 mg or documented maximum tolerated dose [MTD]) for at least 8 weeks before Screening. This participant will enter the 2-week single-blind Placebo Run-In Period according to Study Schedule A, or;
    • The participant has an HbA1c between 7.5% and 10.5%, inclusive and has been taking any other DPP-IV inhibitor (with or without metformin) for at least 8 weeks prior to the Screening Visit. A participant who is taking metformin must have received a stable daily dose (≥1500 mg or documented MTD) for at least 8 weeks before Screening. This participant will enter the 8-week Switching Period according to Study Schedule B. Following this 8-week period, the participant must qualify for all Inclusion/Exclusion Criteria prior to entering the 2-Week Placebo Run-in Period by completing the Week ( 3) procedures including having an HbA1c level between 7.5% and 10.5%.

    Note: An enrollment cap may be applied to ensure no more than approximately 20% of randomized participants are receiving a DPP-IV inhibitor without metformin at baseline.

  5. The participant has had no treatment with antidiabetic agents other than DPP-IV inhibitors and metformin within 2 months prior to Screening (Exception: if a participant has received other antidiabetic therapy for ≤7 consecutive days within the 2 months prior to Screening).
