About this trial

First in humans, exploratory, open-label, single-arm, multicentre, non-competitive, dose escalation study to assess the safety and efficacy of CD1a-CAR T therapy in patients with relapsed/refractory (R/R) T-cell acute lymphoblastic leukemia/lymphoma (T-ALL/LL)

Eligibility criteria

Qualifiers

Children older than 2 years or adults, male and female in both groups.

Patients CD1a antigen blast expression ≥20% at inclusion, either immunophenotypically (flow cytometry) or histologically confirmed.

Failure to achieve morphological complete remission (> 5% bone marrow blasts) or persistence of extramedullary disease after at least two cycles of chemotherapy.

First or subsequent relapse, including morphologic or MRD-detectable (≥1x10-4 ) bone marrow and/or extramedullary relapses after at least one standard frontline therapy.

Disqualifiers

Limiting organ dysfunction, such as uncontrolled cardiac (e.g., depressed left ventricular ejection fraction (LVEF), <45%), pulmonary, liver, renal or CNS dysfunction.

Allo-HSCT within a time frame <3 months, or requiring continued immunosuppressive treatment for graft versus host disease (GvHD).

Uncontrolled epilepsy or underlying central nervous system (CNS) severe disease.
