Phase I Trial of a B7-1 (CD80) Gene Modified Autologous Tumor Cell Vaccine in Combination With Systemic Interleukin-2 in Patients With Metastatic Renal Cell Carcinoma

Abstract

The B7-1 gene modified autologous tumor cell vaccine is safe and can be combined with systemic IL-2 with acceptable toxicity. Immunological and clinical responses were observed in some of the patients. A phase II trial is reasonable to determine the efficacy of this approach.
