Enrolling By Invitation
All
Phase 3

This study is for people who were part of a previous Exelixis-sponsored study and are still benefiting from the treatment. It's called a Long-Term Extension Study because it allows participants to keep receiving the treatment if they can't get it elsewhere. Participants must have been doing well with the treatment and must meet certain rules to join. They can't sign up if they have stopped treatment or if the treatment is available in their country.

  • Length: The study is ongoing, allowing continued access to treatment.
  • Visits: Regular check-ins may be required to monitor health and treatment effects.
  • Eligibility: Must have been in a previous Exelixis study and need to continue the treatment.

If you qualify, this study can help you keep getting the treatment you need. It's important to talk to your doctor about whether this study is a good fit for you.
