CART19 Cells Effects in Patients with Relapsed or Refractory Acute Lymphoblastic Leukemia and Non-Hodgkin's Lymphoma (UHKT-CAR19-01)

Safety and Efficacy of Anti-CD19 Chimeric Antigen Receptor-modified Autologous T Cells (CART19) in Patients with Relapsed/refractory CD19+ Acute Lymphoblastic Leukemia and Non-Hodgkin's Lymphoma. a Dose Escalation, Open-label, Phase I Study.

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

Study Overview

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.

Time Frame
Incidence of adverse events
Time Frame: 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.
Up to 2 years post treatment
Assessment of Dose-Limiting Toxicities (DLTs)
Time Frame: Up to 28 days after IMP administration
Incidence of Dose-limiting toxicities (DLTs) during the first 28 days after IMP administration
Up to 28 days after IMP administration

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Complete remission ( CR) rate
Time Frame: 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
CR rate at 100 days and 6 months after IMP administration
Overall Survival
Time Frame: 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
OS at 1 year after IMP administration
Quality of life using the European Organization for the Research and Treatment of Cancer 30 item questionnaire (EORTC QLQ-C30).
Time Frame: 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.
At 6 months and 1 year following IMP administration

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
CART19 cells in peripheral blood, bone marrow and cerebrospinal fluid
Time Frame: Up to 24 months
Assessment of quantity and phenotype of CART19 cells in peripheral blood, bone marrow and cerebrospinal fluid using using flow-cytometry
Up to 24 months
