ARD-101 for Treatment of PWS: The Hunger Elimination or Reduction Objective Trial
Recruiting
The goal of this clinical trial is to learn if ARD-101 works to treat hyperphagia-related behavior in patients with Prader-Willi syndrome (PWS). It will also teach us about the safety of ARD-101. The main questions it aims to answer are: * Does ARD-101 improve the total score of the HQCT-9 (hyperphagia questionnaire for clinical trials, 9 questions)? * What medical problems do participants have when taking ARD-101? Researchers will compare ARD-101 to a placebo (a look-alike substance that con... Read More
