Full Title of Study: “Anti-Obesity Phentermine-Topiramate Extended Release Pharmacotherapy vs Placebo Among Patients Using a Wearable Activity Tracker.”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Double (Participant, Investigator)
  • Study Primary Completion Date: June 13, 2022

Interventions

  • Drug: Phentermine-Topiramate Extended Release
    • Dosing of 3.75/23 mg daily for 15 days, increased to 7.5/46 mg daily
  • Drug: Placebo
    • Placebo looks exactly like the study drug, but it contains no active ingredient
  • Other: Online support system
    • VitalCare (VitalTech Affiliates LLC) is a digital health platform that allows remote collection of date from the wearable tracker and digital wellness devices used as part of this study. It also will allow subjects to document study medication compliance and will allow the remote visits to be conducted through a video conference between subjects and appropriate study team members.

Arms, Groups and Cohorts

  • Active Comparator: Phentermine – Topiramate Extended Release group
  • Placebo Comparator: Placebo Group

Clinical Trial Outcome Measures

Primary Measures

  • Body Weight Change
    • Time Frame: baseline, 3 months
    • Change in weight calculated in kilograms.

Secondary Measures

  • Body Weight Change
    • Time Frame: baseline, 12 months
    • Change in weight calculated in kilograms.
  • Change in Step Count
    • Time Frame: baseline,12 months
    • The change in the number of steps per day
  • Change in Calories
    • Time Frame: baseline, 12 months
    • The change in calories burned per day
  • Exercise Sessions
    • Time Frame: 12 months
    • The number of exercise sessions per week
  • Tracker Usage
    • Time Frame: 12 months
    • The amount of time in minutes the tracker was used per week
  • Change in SF-12 Physical Score (Health-related Quality Quality of Life)
    • Time Frame: baseline, 12 months
    • Quality of life SF12 physical score. The SF-12 is a well-validate measure of health-related quality of life; providing a physical and mental health component summary score. Min:0, Max: 100. Higher Score = Worse Outcome
  • Change in SF-12 Mental Score (Health-related Quality Quality of Life)
    • Time Frame: baseline, 12 months
    • Quality of life SF12 mental score. The SF-12 is a well-validate measure of health-related quality of life; providing a physical and mental health component summary score. Min:0, Max: 100. Higher Score = Worse Outcome.
