Due to potential concerns about liver safety (See Detailed Description)

The purpose of this study is to demonstrate no excess risk of cardiovascular (CV) composite events exists following long term treatment with TAK-875 compared with placebo.

The drug being tested in this study is called TAK-875. TAK-875 is being tested to treat people who have diabetes. This study will look at the number of cardiovascular events (for example, heart attacks) of people who take TAK-875 in comparison to placebo in addition to standard care.

The study will enroll approximately 5000 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need):

• TAK-875 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. All participants will be asked to record any time they have low blood sugar symptoms in a diary.

This multi-centre trial will be conducted worldwide, in approximately 700 sites. The overall time to participate in this study is 6 years. Participants will make up to approximately 24 visits to the clinic, with telephone visits conducted on an alternate 6 month schedule starting from Month 27.

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.
