NCT05480449 | RECRUITING | B Cell Acute Lymphoblastic Leukemia (B-ALL)

Autologous HuCART19 T Cells Manufactured Using the CliniMACS Prodigy Platform for Pediatric B-ALL (huCART19 Prodigy)
Sponsor:

Stephan Grupp MD PhD

Information provided by (Responsible Party):

Stephan Grupp MD PhD

Brief Summary:

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).

Condition or disease

B Cell Acute Lymphoblastic Leukemia (B-ALL)

B Lineage Lymphoblastic Lymphoma

Intervention/treatment

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

Phase

PHASE1

PHASE2

Detailed Description:

Chimeric Antigen Receptor T-Cells (CAR T) cell therapy has shifted the treatment landscape for pediatric and young adult patients with multiply relapsed and refractory B-ALL (B cell Acute Lymphoblastic Leukemia), however, the manufacturing process remains in its first generation: laborious, time-intensive, and not automated. The time and significant personnel resources in this process can result in patient safety issues - with patients growing sicker, with harder to control leukemias - in the waiting period between T cell collection and completed CAR T cell product manufacture. Use of the CliniMACS Prodigy platform, that allows for semi-automated clinical-scale processing of huCART19 cell products in a functionally closed, sterile system, rapidly, without many of the logistical burdens encountered in the first-generation manufacturing method, can help to surmount these issues. 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.

Accepts Healthy Volunteers:
Criteria
Inclusion Criteria
  • 1. Signed Informed Informed Consent
  • 2. Subjects with documented CD19+ ALL or Lly
    • 1. Cohort A: Subjects with relapsed or refractory ALL or Lly
    • 2. Cohort B: Subjects with poor response to prior B cell directed engineered cell therapy,
    • 3. Subjects with prior or current history of CNS3 disease will be eligible if Central Nervous System (CNS) disease is responsive to therapy (at infusion, must meet criteria in Section 7.6.2).
    • 4. Documentation of CD19 tumor expression in bone marrow, peripheral blood, cerebrospinal fluid (CSF), or tumor tissue by flow cytometry. If the subject has received CD19-directed therapy, flow cytometry should be obtained after this therapy to demonstrate CD19 expression.
    • 5. Age 0-29 years
    • 6. Adequate organ function
    • 7. Adequate performance status defined as Lanksy or Karnofsky performance score ≥50
    • 8. Subjects of reproductive potential must agree to use acceptable birth control methods.
    Exclusion Criteria
    • 1. Active hepatitis B or active hepatitis C
    • 2. HIV infection
    • 3. Active acute or chronic graft-versus-host disease (GVHD) requiring systemic therapy.
    • 4. 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.
    • 5. CNS disease that is progressive on therapy, or with CNS parenchymal lesions that might increase the risk of CNS toxicity.
    • 6. Pregnant or nursing (lactating) women.
    • 7. Uncontrolled active infection.
    • 8. History of seizure disorder that requires ongoing anti-epileptic therapy.
    • 9. If the subject has received previous CAR T cell therapies, history of grade 3 or higher ICANS following administration of a CAR T cell product.
