Objective 1: to characterize the safety and tolerability at pediatric RD for IMJ995 in adult ALL (≥30 y.o.) Objective 2: to characterize the in vivo cellular kinetics of IMJ995 in peripheral blood, bone marrow and other relevant tissues by flow cytometry and qPCR Objective 3: to characterize the incidence and prevalence of immunogenicity (cellular and humoral) to IMJ995 Objective 4: to assess preliminary antitumor activity of IMJ995 in pediatric and AYA ALL and adult ALL as assessed by Complete Remission (CR)/ Complete Remission with Incomplete Hematological Recovery (CRi) rate and duration of response as per local investigator |

Other protocol defined inclusion criteria apply. |
|
E.4 | Principal exclusion criteria |
Key exclusion criteria: Allogeneic HCT within 12 weeks prior to screening Active acute or chronic graft-versus-host disease (GVHD) requiring systemic therapy Presence of isolated extra-medullary disease, testicular involvement or bulky disease (bulky disease defined as lymph node or extra nodal tumor that measures greater than ten centimeters in any dimension) Patients with concomitant genetic syndromes associated with bone marrow failure states, such as patients with Fanconi anemia, Kostmann syndrome, Shwachman syndrome or any other known bone marrow failure syndrome. Patients with Down syndrome will not be excluded Patients with Burkitt’s lymphoma/leukemia (i.e. patients with mature B-ALL, leukemia with B-cell sIg positive and kappa or lambda restricted positivity ALL, with FAB L3 morphology and /or a MYC translocation)
Other protocol defined exclusion criteria apply. |
