Safety and Efficacy of Radio-immunotherapy (RIT) for Patients With Relapse or Refractory Acute Lymphoblastic Leukaemia (ALL) B CD22+ (RIT 90YEpra)

June 24, 2014 updated by: Nantes University Hospital

Evaluation of the Efficacy and Tolerance of Fractionated Radio-immunotherapy With 90Y-Epratuzumab (90Y-hLL2) for Relapsed or Refractory CD22+ B-Acute Lymphoblastic Leukaemia Patients

The purpose of this study is to determine whether fractionated RIT with Epratuzumab and radiolabeled Epratuzumab are effective in the treatment of relapsing or refractory ALL.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Epratuzumab and 90Y-Epratuzumab
Escalating dose schedule with 5 cohort. For each cohort 3 patients will receive Radio-immunotherapy (RIT ) at Day 1 and Day 8 ± 2 First cohort : 92,5 MBq/m² of 90Y-DOTA-hLL2 associated with hLL2 Second cohort : 185 MBq/m² d'90Y-DOTA-hLL2 associated with hLL2 Third cohort : 277,5 MBq/m² d'90Y-DOTA-hLL2 associated with hLL2 Fourth cohort : 370 MBq/m² d'90Y-DOTA-hLL2 associated with hLL2 Fifth cohort : 462.5 MBq/m² d'90Y-DOTA-hLL2 associated with hLL2
Sequential injections of each product with an escalating dose for radiolabeled Epratuzumab between patients

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Determination of MTD by evaluation of hematological and non hematoligical toxicity
The primary endpoint is to evaluate the incidence of dose limiting toxicities (DLT) in order to determine the maximal tolerated dose (MTD) in a dose escalating study design

Secondary Outcome Measures

Outcome Measure
Measure Description
rate of haematological response
To determine the hematologic response
