12-Week Study of DS-8500a in Subjects With Type 2 Diabetes Mellitus on Metformin

8. februar 2019 opdateret af: Daiichi Sankyo, Inc.

A Randomized, Double-Blind, Placebo-Controlled With Active Comparator, 12-Week Study of DS-8500a in Subjects With Type 2 Diabetes Mellitus on Metformin

The hypothesis of this Phase 2, 12-week study, is that DS-8500a will improve glycemic control relative to placebo, based on changes in HbA1c, with acceptable safety and tolerability, in patients with Type 2 Diabetes Mellitus (T2DM) who are treated with metformin.

Foranstaltningsbeskrivelse
Tidsramme
Change From Baseline in Glycated Hemoglobin (HbA1c) at Week 12
Tidsramme: Baseline, Week 12
Glycated hemoglobin is a form of hemoglobin that is measured primarily to identify the three-month average glucose concentration in the blood. Target HbA1c for Type 2 diabetics was less than 7% at the time of this trial. Negative scores show improvement from baseline.

Tidsramme
Change From Baseline in Total Cholesterol (TC) at Week 12
Tidsramme: Baseline, Week 12
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. The equation to calculate total cholesterol is: LDL + HDL + (triglycerides/5) = total cholesterol.
Baseline, Week 12
Change From Baseline in LDL-C at Week 12
Tidsramme: Baseline, Week 12
LDL-C is known as the "bad" cholesterol, so a lower score (negative change) means improvement.
Baseline, Week 12
Change From Baseline in HDL-C at Week 12
Tidsramme: Baseline, Week 12
HDL-C is known as the "good" cholesterol, so a higher score (positive change) means improvement.
Baseline, Week 12
Change From Baseline in Non-HDL-C at Week 12
Tidsramme: Baseline, Week 12
Non-HDL-C is the measure of "bad" cholesterol in the blood, including triglycerides and LDL-C, so a negative change means improvement. The equation for Non-HDL-C = LDL-C + (triglycerides/5).
Baseline, Week 12
Change From Baseline in Triglycerides at Week 12
Tidsramme: Baseline, Week 12
Triglycerides are a type of fat found in the blood. The body uses them for energy. Some triglycerides are needed for good health. But high triglycerides might raise the risk of heart disease. Since Type 2 diabetics tend to have high triglycerides, a negative change means improvement.
Baseline, Week 12
Change From Baseline in Area-Under-the Curve 0-3 Hours (AUC0-3h) of Plasma Glucose (PG) in Response to the Mixed Meal Tolerance Test (MMTT) at Week 4
Tidsramme: Baseline, Week 4
The MMTT requires a participant to drink a "mixed meal," such as Boost or Ensure, that contains protein, carbohydrates, and fat. The goal of the test is to find out how much insulin the pancreas makes in response to food by measuring the level of glucose in the blood. The lower the level of glucose in the blood during the first three hours after the test (AUC0-3h), the more insulin the body has made in response to the test. This would mean a negative change shows improvement.
Baseline, Week 4
Change From Baseline in AUC0-3h of PG in Response to the MMTT at Week 12
Tidsramme: Baseline, Week 12
The MMTT requires a participant to drink a "mixed meal," such as Boost or Ensure, that contains protein, carbohydrates, and fat. The goal of the test is to find out how much insulin the pancreas makes in response to food by measuring the level of glucose in the blood. The lower the level of glucose in the blood during the first three hours after the test (AUC0-3h), the more insulin the body has made in response to the test. This would mean a negative change shows improvement.
Baseline, Week 12
Change From Baseline in Maximum Concentration (Cmax) of PG in Response to MMTT at Week 4
Tidsramme: Baseline, Week 4
Cmax measures the highest amount of glucose in the blood, so a negative change means improvement.
Baseline, Week 4
Change From Baseline in Cmax of PG in Response to MMTT at Week 12
Tidsramme: Baseline, Week 12
Cmax measures the highest amount of glucose in the blood, so a negative change means improvement.
Baseline, Week 12
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 2
Tidsramme: Baseline, Week 2
Normal fasting plasma glucose -- 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 means improvement.
Baseline, Week 2
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 4
Tidsramme: Baseline, Week 4
Normal fasting plasma glucose -- 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 means improvement.
Baseline, Week 4
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 8
Tidsramme: Baseline, Week 8
Normal fasting plasma glucose -- 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 means improvement.
Baseline, Week 8
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 12
Tidsramme: Baseline, Week 12
Normal fasting plasma glucose -- 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 means improvement.
Baseline, Week 12
Count of Participants With HbA1c Less Than 7.0% at Week 12
Tidsramme: Week 12
HbA1C less than 7% is the success goal for many Type 2 diabetics.
