Fasiglifam 25 mg BID vs 50 mg QD

Phase 2

Terminated

• Conditions: Type 2 Diabetes Mellitus
• Interventions: Drug: Fasiglifam; Drug: Placebo to fasiglifam

• Registration Number: NCT01982253
• Lead Sponsor: Takeda

Brief Summary

To evaluate the efficacy of fasiglifam 25 mg twice daily (BID) and fasiglifam 50 mg once daily (QD) on glycemic control in adults with type 2 diabetes who are inadequately controlled on diet and exercise alone.

Detailed Description

The drug being tested in this study is called fasiglifam. Fasiglifam is being tested to treat people who have diabetes. This study will look at glycemic control in people who take fasiglifam.

The study will enroll approximately 400 patients. Participants will be randomly assigned (by chance) 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):

* Fasiglifam 25 mg twice a day

* Fasiglifam 50 mg once daily

* 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 twice each day throughout the study. All participants will be asked to record any time they have symptoms of hypoglycemia in a diary.

This multi-center trial will be conducted worldwide. The overall time to participate in this study is 18 weeks. Participants will make 9 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.

3. Is male or female and 18 years of age or older with a historical diagnosis of Type 2 Diabetes Mellitus (T2DM).

5. Has been treated with diet and exercise but has not received treatment with antidiabetic agents within 12 weeks prior to Screening Visit (Exception: if a patient has received other antidiabetic therapy for ≤7 days in total within the 2 months prior to Screening Visit).
6. Has a body mass index (BMI) ≤45 kg/m^2 at Screening.
7. If regularly using other, non-excluded medications, must be on a stable dose for at least 4 weeks prior to Screening Visit. However, as needed (PRN) use of prescription or over-the-counter medications is allowed at the discretion of the investigator.
8. 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.
