Study Summary

This trial looks for biomarkers that could help predict how someone will respond to weight loss, in terms of their metabolism.

Who is the study for?
This trial is for individuals with a BMI of 30 or higher, from any ethnic background. It's not suitable for those with heart disease, active cancer, post-transplant patients, weight over 400 lbs., HIV/AIDS, pregnant or breastfeeding women, smokers, and people with liver or kidney disease, diabetes (type 1 or type 2), or hypertension.Check my eligibility
What is being tested?
The study tests if phentermine-topiramate combined with lifestyle changes affects metabolic adaptation after weight loss differently than just lifestyle changes and meal replacements. Researchers are looking at how the body adjusts its energy use during and after dieting.See study design
What are the potential side effects?
Phentermine-topiramate can cause dry mouth, constipation, numbness in limbs; it may also affect mood and sleep. Lifestyle interventions might lead to temporary fatigue or hunger.

Why did patients apply to this trial?

Obesity: BMI about 32. Little fluctuation of weight gain or less: seem to be at a set point.
PatientReceived no prior treatments
I'm tired of struggling with weight, dieting, and medication causing weight gain. I want to be able to run or go up stairs without strain.
PatientReceived 1 prior treatment
I have had a rough couple years of being unable to work out, and spend a long amount of time in my car driving for work. Since moving to Wisconsin from Oklahoma, I have gained 45 pounds and have battled to to lose it.
PatientReceived no prior treatments
I have chronic pain, migraines, fibromyalgia, osteoporosis, and a number of other health conditions. Being obese doesn’t help these conditions get better or my disability. A long time ago I lost a lot of weight with the help of a medication that is no longer on the market and I can’t afford the medication but would love to be in a study to help myself and other people to lose weight. Thank you for your consideration!! Donna.
