What is being measured

The primary outcome is the main question the study is designed to answer.

Co-Primary Outcome: Percent Change in Body Weight
Percent change in body weight from Baseline to Day 171 is presented.
Measured: Baseline to Day 171
Co-Primary Outcome: Percentage of Subjects Who Achieve Body Weight Loss ≥ 5%
Percentage of participants who achieve a body weight loss ≥ 5% from Baseline to Day 171 is presented.
Measured: Baseline to Day 171

Secondary outcomes (5)

Percent Body Weight Change in Subjects With Impaired Plasma Glucose Status at Baseline
Impaired plasma glucose status is defined as Fasting Plasma Glucose (FPG) ≥100mg/dL and <126mg/dL at baseline measurement.
Measured: Baseline to Day 171
Change in Plasma Glucose Status (Normal, Impaired, Diabetic) in Subjects With Impaired Plasma Glucose Status at Baseline.
Normal plasma glucose status is defined FPG ≤ 100mg/dL. Impaired plasma glucose status is defined as FPG ≥100mg/dL and <126mg/dL. Diabetic plasma glucose status was defined as FPG >126mg/dL.
Measured: Baseline to Day 171
Percent Change in Plasma Glucose
Percent change in Plasma Glucose in subjects with impaired glucose and T2D at baseline. Impaired plasma glucose is defined as FPG≥100mg/dL and FPG<126mg/dL.
Measured: Baseline to Day 171
Change in Body Mass Index (BMI)
The BMI was calculated using height (in cm) and weight (in kg) according to the following formula: BMI (kg/m2((superscript 1)) = Weight (kg)/[Height (cm)/100]2(superscript2).
Measured: Baseline to Day 171
Change in Hemoglobin HbA1c in Subjects With Type 2 Diabetes at Baseline
To assess the decrease in HbA1c after repeated administration of Gelesis 100 over a period of 168 days in overweight and obese people with type 2 diabetes, The glycosylated hemoglobin was measured in mmol/mol.
Measured: Baseline to Day 171
