A Phase I Trial of Autologous CLL B Cells Transduced to Express Chimeric CD154 (ISF35)
Completed · Phase 1
Conditions studied: Chronic Lymphocytic Leukemia
In brief
The study is a Phase I, dose-escalating, non-randomized, single institution clinical trial assessing the safety and efficacy of autologous Ad-ISF35-transduced CLL B cells administered as a single intravenous infusion in patients with chronic lymphocytic leukemia (CLL).
