Frequently Asked Questions

Common questions about Prader-Willi Syndrome clinical trials

A clinical trial is a carefully designed research study that tests new medical treatments, drugs, devices, or approaches in human volunteers. Every approved medication and treatment available today was proven safe and effective through clinical trials.

All clinical trials are reviewed and approved by Institutional Review Boards (IRBs) — independent committees that evaluate patient safety. Trials follow strict protocols, and your health is monitored closely throughout. You can withdraw at any time.

Not necessarily. Many trials compare the new treatment against the current standard of care, meaning all participants receive active treatment. When placebos are used, they are typically combined with standard treatment, not given alone. The trial description will always specify the design.

Under the Affordable Care Act, most private insurers are required to cover routine patient care costs during a clinical trial. The sponsor typically covers the investigational treatment itself. Medicare also covers routine costs for qualifying trials.

Yes. Participation is completely voluntary. You can withdraw at any time, for any reason, without it affecting your access to standard medical care.

Each trial has specific eligibility criteria — including age, diagnosis, disease stage, prior treatments, and general health. Browse the trials listed above and check their eligibility sections. You can also contact the trial site directly to discuss your situation.

A study on the satiety effect of Caralluma fimbriata extract for people with Prader - Willi syndrome (PWS).”

Prader-Willi syndrome (PWS) PWS is caused by three types of abnormality in chromosome 15 at a prevalence rate of 1:11,000 to 1:22,000. The defining feature of PWS is food-seeking behaviour due to constant hunger. Hyperphagia and obesity are one of the main burdens in PWS and obesity is linked to increased morbidity and mortality.
