Summary

Primary Objective: To estimate the incidence of treatment-emergent and treatment-related adverse events during treatment with blinatumomab in pediatric and adolescent subjects with B-precursor ALL in second or later bone marrow relapse, in any marrow relapse after alloHSCT, or refractory to other treatments Secondary Objective(s): To describe key efficacy outcomes, including incidence of complete response (CR) within 2 cycles of blinatumomab, minimal residual disease (MRD) remission within 2 cycles of blinatumomab, relapse free survival (RFS), overall survival (OS), incidence of alloHSCT, and 100-day mortality after alloHSCT. Hypotheses: A formal statistical hypothesis will not be tested. The incidence of treatment-emergent and treatment-related adverse events will be estimated. Study Endpoints: * Incidence of treatment-emergent and treatment-related adverse events * Incidence of CR within 2 cycles of blinatumomab * MRD remission within 2 cycles of blinatumomab * RFS * OS * Incidence of alloHSCT * 100-day mortality after alloHSCT Study Design: Multi-center, open-label, single-arm expanded access protocol

Conditions

• Relapsed/Refractory B-Precursor Acute Lymphoblastic Leukemia

Interventions

Type	Name	Description
DRUG	Blinatumomab	A single cycle of blinatumomab (CIVI) treatment is 6wks, 4wks of treatment followed by a 2wk treatment-free interval. Up to 5 cycles will be administered per subject. In the first cycle, for patients with an M3 bone marrow, the initial dose will be 5μg/m2/day for the first 7days, escalated to 15μg/m2/day on D8-D29. For all subsequent cycles 15μg/m2/day will be the dose for all 4wks of continuous treatment. In case of M2 bone marrow or M1 bone marrow with an MRD relapse at screening, the initial dose will start at 15μg/m2/day for the first 7days of treatment \& no dose step at D8. For all subsequent cycles the dose will remain 15μg/m2/day. A dose of 9μg/day for the initial dose (if applicable) \& 28μg/day for the escalated dose after dose step should not be exceeded.
OTHER	Extension of LTFU as per ProtocolAmendment7 7Jun18	LTFU (Long Term Follow-Up) will extend past 18 months for patients already ended the study/still on study or to be enrolled at European sites if they did not receive a transplantation after blinatumomab treatment. For subjects to be included in the additional LTFU, data will be captured until subjects are 18yrs old (every 6 months by phone contact). The following will be captured: relapse (medullary or extra-medullary relapse and its specific location), second tumor (which type), alive/died and cause of death, hospitalization and reason for hospitalization.
