Brief summary

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.

Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline in Glycated Hemoglobin (HbA1c) at Week 12Baseline, Week 12Glycated 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.

Secondary

MeasureTime frameDescription
Change From Baseline in LDL-C at Week 12Baseline, Week 12LDL-C is known as the bad cholesterol, so a lower score (negative change) means improvement.
Change From Baseline in HDL-C at Week 12Baseline, Week 12HDL-C is known as the good cholesterol, so a higher score (positive change) means improvement.
Change From Baseline in Non-HDL-C at Week 12Baseline, Week 12Non-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).
Change From Baseline in Triglycerides at Week 12Baseline, Week 12Triglycerides 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.
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 4Baseline, Week 4The 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.
Change From Baseline in AUC0-3h of PG in Response to the MMTT at Week 12Baseline, Week 12The 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.
Change From Baseline in Total Cholesterol (TC) at Week 12Baseline, Week 12Total 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.
Change From Baseline in Cmax of PG in Response to MMTT at Week 12Baseline, Week 12Cmax measures the highest amount of glucose in the blood, so a negative change means improvement.
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 2Baseline, Week 2Normal 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.
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 4Baseline, Week 4Normal 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.
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 8Baseline, Week 8Normal 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.
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 12Baseline, Week 12Normal 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.
Count of Participants With HbA1c Less Than 7.0% at Week 12Week 12HbA1C less than 7% is the success goal for many Type 2 diabetics.
Change From Baseline in Maximum Concentration (Cmax) of PG in Response to MMTT at Week 4Baseline, Week 4Cmax measures the highest amount of glucose in the blood, so a negative change means improvement.

Change From Baseline in Glycated Hemoglobin (HbA1c) at 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.

Time frame: Baseline, Week 12

Population: Modified Intent to Treat (mITT) Set, defined as all participants in the Safety Set who have a baseline measurement and at least 1 post-baseline measurement. mITT was used for analysis because one of the sites had a fire so 16 participants who were included in the baseline population were not included in analyses.

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.

Change From Baseline in Fasting Plasma Glucose (FPG) at 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.

Change From Baseline in Total Cholesterol (TC) at 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.

Change From Baseline in Triglycerides at 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.
