Randomized, Double-blind, Active-controlled, Study of Rivoglitazone in Type 2 Diabetes Mellitus
May 6, 2021 updated by: Daiichi Sankyo, Inc.
A Randomized, Double-blind, Placebo, and Active Comparator-controlled, Parallel-group Study of the Efficacy and Safety of Rivoglitazone as Monotherapy Treatment of Type 2 Diabetes Mellitus
This is a 26-week, multicenter, randomized, double-blind, placebo and active comparator-controlled, parallel-group study in participants with type 2 diabetes currently sub-optimally controlled by diet and exercise or with non-thiazolidinedione antihyperglycemic monotherapy.
Pioglitazone is used as active comparator.
The total duration of a participant's participation will be approximately 30 weeks, including a 2-week placebo lead-in period, a 26-week double-blind treatment period, and a 2-week post-treatment follow-up period.
Participants who complete the randomized portion of the study per protocol may have the opportunity to continue in a long-term extension study of active treatments.

Time Frame: Baseline up to week 2, week 4, week 6, week 8, week 12, week 16, and week 20 post-dose.
|
Normal fasting plasma glucose (FPG) -- or blood sugar -- is between 70 and 100 milligrams per deciliter (mg/dL) for people who do not have diabetes.
People with Type 2 diabetes typically have FPG that is too high, so a negative change from baseline and a lower FPG means improvement.

|
Total cholesterol is a measure of the total amount of cholesterol in the blood, including low-density lipoprotein cholesterol (LDL-C) - the "bad" cholesterol, high-density lipoprotein cholesterol (HDL-C) - the "good" cholesterol, and triglycerides.
