About this trial

This study seeks to examine the efficacy and safety of the administration of autologous T cells that have been modified through the introduction of a chimeric antigen receptor (CAR) targeting the B cell surface antigen CD19 following administration of chemotherapy lymphodepletion regimen in children with relapsed or refractory acute lymphoblastic leukemia (ALL) or lymphoma. The overall goal of this study is to validate the safety profile of administration CD19-CAR T cells and describe the response rate in children with relapsed/refractory ALL or lymphoma.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Subjects must have relapsed or refractory ALL or lymphoma treated with at least two lines of therapy. Disease must have either progressed after the last regimen or presented failure to achieve partial or complete remission with the last regimen.

The patient's disease must be CD19 positive, either by immunohistochemistry or flow cytometry analysis on the last biopsy available.

Age 1-17 years.

Performance status: Subjects > 10 years of age: Karnofsky ≥ 50%; Subjects ≤ 10 years of age: Lansky scale ≥ 50%.

Disqualifiers

Autologous transplant within 6 weeks of planned CAR T cell infusion.

Recipient of CAR-T cell therapy outside of this protocol.

Active central nervous system (CNS) or meningeal involvement by tumor.

History of additional active malignancy other than non-melanoma skin cancer, carcinoma in situ (e.g. cervix, bladder, breast).

Trial outcomes

Primary outcomes

1

Complete response rate (CRR) for ALL and Overall response rate (ORR) for lymphoma

Complete response for ALL was defined as leukemic cells \<5% in bone marrow. Overall response for lymphoma was defined as complete response plus partial response defined by Lugano criteria.

Time frame
1 month for subjects with ALL, and 3 months for subjects with lymphoma
2

Incidence and severity of adverse events

Severity of adverse events are graded according to CTCAEv5.0.

Time frame
through study completion, an average of 6 months

Secondary outcomes

1

Frequency of minimal residual disease for ALL

Measurable residual disease in bone marrow by flow cytometry or PCR methods.

Time frame
1 month
2

Overall survival

survival as estimated by Kaplan-Meier method. Death from any cause is considered as event for analysis.

Time frame
1 year
3

Event-free survival

Event-free survival as estimated by Kaplan-Meier method. Events are death from any cause, or relapse or progression of underlying disease.

Time frame
1 year
4

Proportion of products successfully manufactured

Success defined as meeting product release criteria with at least 0.2 million cells/kg recipient body weight

Time frame
at the time of CAR-T cell infusion
