Type 2 diabetes mellitus (T2DM) has increased dramatically throughout the world over the past decades despite the availability of several different treatment options. Current pharmacologic treatments include insulin, thiazolidinediones, sulfonylureas, metformin, dipeptidyl-peptidase-4 (DPP-4) inhibitors, and glucagon-like peptide-1 (GLP-1) mimetics. A number of these treatments are associated with clinically important side effects such as low blood sugar (hypoglycemia), weight gainflud retention, exaggeration of pre-existent heart failure, and gastrointestinal side effects. These side effects and the disadvantages associated with many of the currently available antidiabetic agents can reduce compliance and limit their long-term use.~Insulin is a hormone that is produced by the body to regulate blood sugar (glucose). In individuals with T2DM, the insulin produced by the body does not effectively control the amount of sugar in the bloodstream. If not properly managed, T2DM may cause elevated blood sugar levels (hyperglycemia) and ultimately result in serious health problems.~In response to this problem, Takeda is developing TAK-875 (an investigational drug) as an addition to diet and exercise to improve blood sugar control in patients with T2DM. TAK-875 may affect the production of insulin and may improve how the body uses the sugar in the blood.~The aim of this study is to find out if TAK-875, when taken for approximately 2 years in combination with current diabetes medicine (called metformin), is safe and effective at helping people with T2DM control their high blood sugar when compared to glimepiride (a type of medication called a sulfonylurea). The study is being done to find out if the combination of TAK-875 plus metformin works as well as the combination of glimepiride plus metformin.~Approximately 2430 patients worldwide aged 18 or over with T2DM, will take part in this study and will be involved in the study for up to 110 or 120 weeks.~TAK-875 is being developed at Takeda Global Research and Development, Inc. as an adjunct to diet and exercise to improve glycemic control in participants with T2DM.~This study will investigate TAK-875 in participants with type 2 diabetes mellitus whose blood sugar level is inadequately controlled with metformin monotherapy.~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.
The purpose of this study is to determine the efficacy and safety of TAK-875, once daily (QD), plus metformin compared to glimepiride plus metformin in participants with type 2 diabetes mellitus (T2DM).~The purpose of this study is to determine the efficacy and safety of TAK-875, once daily (QD), plus metformin compared to glimepiride plus metformin in participants with type 2 diabetes mellitus (T2DM).
