Sipuleucel-t and Temozolomide can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Temozolomide's myelosuppressive and lymphodepleting effects may impair immune activation by sipuleucel-T.
What to do
Avoid concurrent immunosuppressive chemotherapy around leukapheresis and infusion where possible. Review sequencing with the oncology team.
