Primary | Apparent Clearance (CL/F) of Phentermine and Topiramate | A Bayesian analysis was performed to derive posterior Bayes individual pharmacokinetic (PK) parameters. | On Days 14, 28, 42, and 56 | |
Primary | Apparent Volume of Distribution (Vc/F) of Phentermine and Topiramate | A Bayesian analysis was performed to derive posterior Bayes individual PK parameters. | On Days 14, 28, 42, and 56 | |
Primary | Area Under the Curve (AUC) of Phentermine | A Bayesian analysis was performed to derive posterior Bayes individual PK parameters. AUC from time 0 to 24 hours under steady-state. | On Days 14, 28, 42, and 56 | |
Primary | Maximum Concentration (Cmax) of Phentermine | A Bayesian analysis was performed to derive posterior Bayes individual PK parameters. | On Days 14, 28, 42, and 56 | |
Primary | Area Under the Curve (AUC) of Topiramate | A Bayesian analysis was performed to derive posterior Bayes individual PK parameters. AUC from time 0 to 24 hours under steady-state. | On Days 14, 28, 42, and 56 | |
Primary | Maximum Concentration (Cmax) of Topiramate | A Bayesian analysis was performed to derive posterior Bayes individual PK parameters. | On Days 14, 28, 42, and 56 | |
Secondary | Weight Loss | Mean percent weight change from baseline to Day 56 | 56 days | |
Secondary | Change in Waist Circumference | Mean change in waist circumference from baseline to Day 56 | 56 days | |
Secondary | Change in Blood Pressure | Mean change in blood pressure from baseline to Day 56 | 56 days | |
Secondary | Change in OGTT of Fasting and 2-hour Glucose | Mean changes in glycemic parameters (OGTT of fasting and 2-hour glucose) from baseline to Day 56 | 56 days | |
Secondary | Change in Lipid Parameters | Mean percent changes in lipid parameters, including total cholesterol, LDL-C, HDL-C and triglycerides (TG) from baseline to Day 56 | 56 days | |
Secondary | Change in Visual Analog Scale (VAS) Hunger Scores | Mean change in visual analog scale (VAS) hunger scores from baseline to Day 56. VAS hunger score is measured using a 10.0 cm horizontal line. The left end of this line is defined by word descriptors "not at all hungry" and corresponds to a VAS hunger score of 0.0. The right end of this line is defined by word descriptors "extremely hungry all the time" and corresponds to a VAS hunger score of 10.0. Subjects were asked "Please mark with a perpendicular line on the scale how hungry you were overall during the past week:" to best describes their overall level of hunger during the past week. Research staff measure the distance between the "0.0 = not at all hungry" anchor and the mark made by the subject (length to the nearest tenth of a centimeter) to score the measure. | 56 days | |
Secondary | Change in Visual Analog Scale (VAS) Satiety Scores | Mean change in visual analog scale (VAS) satiety scores from baseline to Day 56. VAS satiety score is measured using a 10.0 cm horizontal line. The left end of this line is defined by word descriptors "very satisfied" and corresponds to a VAS satiety score of 0.0. The right end of this line is defined by word descriptors "not all at satisfied" and corresponds to a VAS satiety score of 10.0. Subjects were asked "Please mark with a perpendicular line on the scale how satisfied you were after eating during the past week:" to evaluate how satisfied subjects are after eating during the past week. Research staff measure the distance between the "0.0 = very satisfied" anchor and the mark made by the subject (length to the nearest tenth of a centimeter) to score the measure. | 56 days | |
Secondary | Change in HOMA-IR | Mean changes in glycemic parameters (HOMA-IR) from baseline to Day 56 | 56 days | |
Secondary | Change in Whole Body Insulin Sensitivity Index (WBISI) (Matsuda) | Mean changes in glycemic parameters [Whole Body Insulin Sensitivity Index (WBISI) (Matsuda)] from baseline to Day 56. The Oral Glucose Tolerance Test (OGTT) were performed at Baseline and Day 56 using 75 g oral glucose load; blood samples were obtained at baseline and at 2 hours post glucose load for evaluation of both glucose and insulin levels. Insulin Sensitivity was measured by obtaining glucose and insulin levels in a fasting state and at 2 hours after administration of oral glucose load. Matsuda index = 10,000/SQRT [glucose concentration (mg/dL) (fasting)*insulin concentration (uIU/mL) (fasting)*glucose concentration (mg/dL) (2 hours after glucose load)*insulin concentration (uIU/ mL) (2 hours after glucose load)], with higher numbers indicating better insulin sensitivity. | 56 days |
