Brief Summary:
PATH for PWS is a study to help researchers better understand serious medical events in PWS over a 4-year period, as well as evaluate how PWS-related behaviors change over time. The data from this study is intended to inform the development and clinical trial design of potential new treatments.

Condition or disease
Prader-Willi Syndrome

Detailed Description:
Every 6 months, participants or their caregivers will be asked to update online surveys about medical problems and serious medical events, as well as provide information about conditions and behaviors often associated with PWS such as hyperphagia. Because this is an observational study, no study drug will be provided and no visits to a doctor or clinic are required.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Evaluate the incidence of serious medical events [ Time Frame: Up to 4 years ]
    Serious medical events are those that result in death, are life-threatening, require hospitalization or an emergency room visit, or are medically significant


Secondary Outcome Measures :
  1. Evaluate the incidence of non-serious thrombotic events [ Time Frame: Up to 4 years ]
    Thrombotic events include blood clots in a blood vessel, such as an artery or vein

  2. Analyze D-dimer concentrations in a subset of participants who agree to provide a blood sample [ Time Frame: Up to 4 years ]
    D-dimer is a protein in the blood that is present when a blood clot is forming or has formed

  3. Evaluate prescription medication use associated with serious medical events and thrombotic events [ Time Frame: Up to 4 years ]
  4. Evaluate the change in weight [ Time Frame: Up to 4 years ]
  5. Evaluate the change in height [ Time Frame: Up to 4 years ]
  6. Evaluate the change in height-adjusted weight [ Time Frame: Up to 4 years ]
  7. Evaluate PWS complexity using an online survey [ Time Frame: Up to 4 years ]
  8. Evaluate the pattern of hyperphagia behaviors using an online survey [ Time Frame: Up to 4 years ]
    Hyperphagia means the intense, constant hunger that often occurs in individuals with PWS

  9. Evaluate hyperphagia management using an online survey [ Time Frame: Up to 4 years ]
  10. Evaluate food-related behaviors using an online survey [ Time Frame: Up to 4 years ]
  11. Analyze medical information to evaluate the natural history of PWS [ Time Frame: Up to 4 years ]
    Medical information will be from birth to before enrolling in the study
