About this trial

This study will determine the safety and efficacy of moving to a second-generation manufacturing process using the CliniMACS Prodigy platform to manufacture huCART19 cells for patients with B cell Acute Lymphoblastic Leukemia (B-ALL).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Signed Informed Informed Consent

Disqualifiers

Active hepatitis B or active hepatitis C

HIV infection

Active acute or chronic graft-versus-host disease (GVHD) requiring systemic therapy.

Concurrent use of systemic steroids or immunosuppression at the time of cell infusion or cell collection, or a condition, in the treating physician's opinion, that is likely to require steroid therapy or immunosuppression during collection or after infusion. Steroids for disease treatment at times other than cell collection or at the time of infusion are permitted. Use of physiologic replacement hydrocortisone or inhaled steroids is permitted as well.

Trial design

Design model

Sequential

Treatments tested in this trial

  • Autologous Humanized CD19-Directed Chimeric Antigen Receptor T-Cells (huCART19)

    Biological/Vaccine

    The investigational agent in this protocol is humanized CART19 cells (huCART19). Autologous T cells will be engineered to express an extracellular single chain antibody (scFv) with specificity for CD19. This will be expected to redirect specificity of the transduced T cells for cells that express CD19, a molecule that is restricted in expression on the surface of the malignant cells and on normal B cells.

Trial outcomes

Primary outcomes

1

Safety of huCART19 Administration

The safety of the administering Humanized Cd19-Directed Chimeric Antigen Receptor T-Cells (huCART9) will be measured by the monitoring the frequency and severity of adverse events in patients with advanced or refractory CD19+ hematologic malignancies, including those previously treated with cell therapy.

Time frame
5 years
2

Efficacy of huCART19 Administration

The efficacy of huCART9 will be measured by the evaluating the overall response rate in patients with advanced or refractory CD19+ hematologic malignancies, including those previously treated with cell therapy.

Time frame
5 years

Secondary outcomes

1

Manufacturing Feasibility

Manufacturing feasibility will be measured by the percentage of manufactured products that do not meet release criteria for vector transduction efficiency, T cell product purity, viability, sterility, or due to tumor contamination.

Time frame
5 years
2

Safety of huCART19 as measured by ≥ Grade 3 toxicity rate

Safety of huCART19 as measured by ≥ Grade 3 toxicity rate (toxicity that is possibly attributed to huCART19) that is unmanageable, unexpected, and unrelated to chemotherapy.

Time frame
5 years
3

Anti-tumor response due to huCART19 cell infusions

For subjects with detectable disease, measure anti-tumor response due to huCART19 cell infusions, as defined by the presence of medullary (morphologic or Minimal Residual Disease (MRD-level disease) and/or extramedullary disease at 1-month post-infusion.

Time frame
5 years
4

Remission Rate

Overall remission rate will be measured by the proportion of treated subjects who achieve complete morphologic remission at Day 28 post huCART19 infusion.

Time frame
5 years
