Study Details

Study Description

Brief Summary

Phase I Dose Escalation Study of CART19 Cells for Adult Patients With Relapsed / Refractory Acute Lymphoblastic Leukemia and Non-Hodgkin's Lymphoma.

Condition or Disease Intervention/Treatment Phase
  • Drug: Autologous CAR19 T lymphocytes
Phase 1

Detailed Description

This is an open-label, single arm study on up to 24 adult subjects with refractory or relapsed CD19+ Non-Hodgkin's Lymphoma or B-ALL. Following lymphodepleting conditioning regimen, the patients will receive a single dose of autologous CAR19 T lymphocytes provided by the sponsor´s manufacturing facility. CART19 dose will be escalated in consecutive patients using accelerated titration design in order to establish recommended CART19 dose for further study, which will be either Maximum Tolerated Dose (MTD) or Maximum Feasible Dose (MFD), whichever is reached first.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Autologous CAR19 T lymphocytes

Drug: Autologous CAR19 T lymphocytes
First-in-human trial examining the safety and efficacy of CART19 in r/r B-ALL and B-NHL

Outcome Measures

Primary Outcome Measures

  1. Incidence of adverse events [Up to 2 years post treatment]

    Cumulative incidence of IMP-related adverse events (AEs) graded by ASTCT consensus grading criteria for Cytokine Release Syndrome (CRS) and Immune effector cell-associated neurotoxicity syndrome (ICANS) and by Common Terminology Criteria for Adverse Events (CTCAE) v 5.0 for other AEs. Toxicities will be followed from the start of Blood Collection or Apheresis until the end of the study.

  2. Assessment of Dose-Limiting Toxicities (DLTs) [Up to 28 days after IMP administration]

    Incidence of Dose-limiting toxicities (DLTs) during the first 28 days after IMP administration

Secondary Outcome Measures

  1. Complete remission ( CR) rate [CR rate at 100 days and 6 months after IMP administration]

    Assessment of the efficacy of IMP cells administration in patients with refractory or relapsed CD19+ NHL and B-ALL evaluated by Complete Remission rate

  2. Overall Survival [OS at 1 year after IMP administration]

    Assessment of the efficacy of IMP cells administration in patients with refractory or relapsed CD19+ NHL and B-ALL evaluated by Overall Survival

  3. Quality of life using the European Organization for the Research and Treatment of Cancer 30 item questionnaire (EORTC QLQ-C30). [At 6 months and 1 year following IMP administration]

    EORTC-QLQ-C30 is a 30-item subject self-report questionnaire composed of both multi-item and single scales, including a global health status/quality of life (GHS/QoL) scale. Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." A change of 5 - 10 points is considered a small. A change of 10 - 20 points is considered a moderate change.

Other Outcome Measures

  1. CART19 cells in peripheral blood, bone marrow and cerebrospinal fluid [Up to 24 months]

    Assessment of quantity and phenotype of CART19 cells in peripheral blood, bone marrow and cerebrospinal fluid using using flow-cytometry
