Brief Title: A Phase Ib Study of ISF35 in Combination With Chemotherapy (FCR) in Subjects With Relapsed, Refractory, and/or 17p- CLL
Official Title: A Phase 1b Study of Repeated Doses of Autologous CLL B Cells Transduced to Express Chimeric CD154 (ISF35) in Combination With Fludarabine, Cyclophosphamide and Rituximab (FCR) in Subjects With Chronic Lymphocytic Leukemia (CLL)
Study ID: NCT00772486
Brief Summary: The study is a Phase 1b open label, non-randomized, single institution clinical trial that is designed to evaluate the safety and tolerability of three repeat infusions of ISF35 followed by a standard regimen of three cycles of fludarabine, cyclophosphamide and rituximab (FCR) in subjects with refractory, resistant, and/or 17p- CLL.
Detailed Description: ISF35 has already been used in two Phase I clinical trials. The trials demonstrated that ISF35 treatment is well tolerated and patients did not experience any significant or unexpected adverse events. Patients reported flu-like symptoms from ISF35, which disappeared within one to three days. The trials also showed that ISF35 stimulates the immune system to act against CLL cells and sensitize leukemic cells to subsequent treatment. Repeat infusions of ISF35 administered as a single agent to subjects with CLL resulted in durable reductions in circulating and lymph-node bound leukemic cells. Furthermore, CLL patients with 17p deletion responded to standard courses of FCR after receiving ISF35 and achieved durable remissions. ISF35 is an abbreviation for Immune Stimulatory Factor 35, an offspring of technology discovered by Dr. Thomas J. Kipps, MD, PhD, Professor, Department of Medicine and Deputy Director for Research,UCSD Moores Cancer Center.
