Subject: Office Director Memo: Indication Statement
Sipuleucel-T (Provenge) is being licensed for the following indication:
PROVENGE is indicated for the treatment of asymptomatic or minimally symptomatic metastatic castrate resistant (hormone refractory) prostate cancer.
This indication reflects the population studied. The product is novel and it is not known if the study results are generalizable to a broader population with more advanced disease. As noted in the clinical reviewers’ memo, pain is a prognostic factor for survival for castrate resistant (hormone refractory) patients and the amount of residual disease could affect the impact of this therapy since Sipuleucel-T is designed to work by an immunological effect.
