The HERO Study Details
Why are we testing ARD-101?
For most people, when they eat, food triggers a signal to be sent to the brain that they should no longer be hungry.
Individuals with PWS are suspected to be missing the signal that suppresses hunger
ARD-101 is being studied to see if it can help the body release certain gut hormones that may help reduce excessive hunger and food-seeking behaviors in people with PWS.
Eligibility
To be eligible for the HERO study, male or female participants must be diagnosed with Prader-Willi Syndrome and be at least 13 years old. They will also need a single, designated caregiver who can communicate well with the investigator, attend clinic visits, complete questionnaires, and monitor food and behavior changes for the entire duration of the study.
Study Details
Eligible participants will receive either active study drug or placebo (no active study drug ingredients). Participants will take the study drug orally twice daily for 12 weeks. The study requires approximately four in-person clinic visits and three telehealth visits, with travel expenses and lodging covered if needed. No fasting is necessary. All participants who complete the HERO study will have the option to receive the active study drug in a follow up study.
