Experimental: GRASPA 50 IU/kg
Each patient will receive GRASPA 50 IU/kg at day 3 of the induction 1 phase.
If no toxicity related to investigational product is observed and if the patient's state of health allows it, a second injection, at the identical dose, will be administered at Day 6 of Induction 2 phase.

Efficacy Primary Endpoint - Percentage of Patients Responding to Treatment
Zeitfenster: 7 days after the first administration of GRASPA® during Induction 1
|
The main evaluation criterion is a composite efficacy/toxicity criterion.
Efficacy, assessed during induction 1: percentage of patients responding to treatment, i.e. with plasma Asn concentration ≤2µM (depleted), for a duration of at least 7 days after the administration of GRASPA®
|
7 days after the first administration of GRASPA® during Induction 1

Safety Endpoint - DLTs Assessed During Induction 1 and Induction 2
Zeitfenster: Induction 1 and Induction 2
