Vaccination by Leukemic Apoptotic Corpse Autologous Pulsed Dendritic Cells for Acute Myelogenous Leukemia (AML) Patients in First or Second Complete Remission (CR)(CD laM)

Vaccination by Leukemic Apoptotic Corpse Autologous Pulsed Dendritic Cells for AML Patients in First or Second CR

Dendritic cells vaccinations are increasingly used in order to develop antitumoral immune response. This will be a Phase 2 trial using autologous dendritic cells pulsed with leukemic apoptotic corpse in acute myelogenous leukemia (AML) patients in first or second Complete remission (CR).
