About this trial

The goal of this prospective, multicentric, single-arm, phase I/II clinical trial is to evaluate the safety and efficacy of a novel CD19-directed CAR-T cell locally produced in an academic institution in Brazil in patients with refractory or relapsed acute lymphoblastic leukemia or non-Hodgkin lymphoma.

Participants will receive a single intravenous infusion of an autologous academic anti-CD19 CAR-T cell and will be followed for 5 years.

Trial design

Design model

Single group

Treatments tested in this trial

  • CART-19

    Biological/Vaccine

    The academic CART-19 consists of autologous T lymphocytes transduced with a lentiviral vector to express a second-generation chimeric antigen receptor with a single chain variable fragment (scFv) targeting the CD19 antigen conjugated with 4-1BB co-stimulatory and CD3z signaling domains.

Trial outcomes

Primary outcomes

1

Safety: Number of participants who experience early adverse events.

To evaluate the occurrence of early adverse events related to the study treatment, from inclusion until 30 days after CAR-T cell infusion.

Time frame
From patient's inclusion until 30 days after CAR-T cell infusion
2

Safety: Number of participants who experience late adverse events.

To evaluate the occurrence of early adverse events related to the study treatment, from week 5 to week 52.

Time frame
From week 5 to week 52

Secondary outcomes

1

Efficacy: Overall Response Rate (ORR)

The combined number of participants achieving Complete Response (CR) or Partial Response (PR) as the best response at day 30 and day 90 after CAR-T cell infusion, determined by the investigators, following Lugano criteria in non-Hodgkin lymphomas; or the combined number of participants achieving Complete Remission (CR) or Complete Remission with Incomplete Hematologic Recovery (CRi) as the best response at day 30 and day 90 after CAR-T cell infusion, determined by the investigators, in Acute Lymphoblastic Leukemia.

Time frame
Day 30 and day 90 after CAR-T cell infusion
2

Efficacy: Event Free Survival (EFS)

The time between patient's inclusion and relapse, disease progression, or death of any cause.

Time frame
From patient's inclusion until 5 years
3

Efficacy: Relapse Free Survival (RFS)

The duration of response, defined as the time from the first complete or partial response to the date of first documentation of relapse, disease progression, or death of any cause.

Time frame
From patient's inclusion until 5 years
4

Efficacy: Overall Survival (EFS)

The number of participants surviving since patient's inclusion until 5 years

Time frame
From patient's inclusion until 5 years

Other outcomes

1

Exploratory: Number of patientes with CAR-T cell persistence over the time

To evaluate the persistence of infused CAR-T cells in patient's peripheral blood over the time

Time frame
From CAR-T cell infusion until 5 years
2

Exploratory: Replication-competent lentivirus (RCL)

To evaluate the presence of replication-competent lentivirus in patient's peripheral blood, after CAR-T cell infusion, in a cohort of 10 patients.

Time frame
From CAR-T cell infusion until 5 years
