About this hub
Expanded access programs (sometimes called compassionate use, named-patient programs, or pre-approval access) allow patients with serious or life-threatening conditions such as Breast Cancer to receive an investigational therapy outside of a controlled clinical trial when no comparable approved option is available. Eligibility, location, and the application process differ for each program — review the individual program pages below for sponsor contact information, inclusion criteria, and the request workflow. Right2Hope is a 501(c)(3) nonprofit and provides this directory free of charge for patients, caregivers, and treating physicians.
