huJCAR014 CAR-T Cells in Treating Adult Patients With Relapsed or Refractory B-Cell Non-Hodgkin Lymphoma or Acute Lymphoblastic Leukemia

• Status: Recruiting
• Trial end date: 2022-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase I trial studies the side effects of huJCAR014 in treating patients with relapsed or refractory B-cell non-Hodgkin lymphoma or acute lymphoblastic leukemia. huJCAR014 CAR-T cells are made in the laboratory by genetically modifying a patient's T cells and may specifically kill cancer cells that have a molecule CD19 on their surfaces.

In Stage 1, dose-finding studies will be conducted in 3 cohorts:

1. Aggressive B cell NHL

2. Low burden ALL

3. High burden ALL

In Stage 2, studies may be conducted in one or more cohorts to collect further safety, PK, and efficacy information at the huJCAR014 dose level(s) selected in Stage 1 for the applicable cohort(s). There are two separate cohorts for stage 2:

1. Cohort 2A, CAR-naïve (n=10): patients who have never received CD19 CAR-T cell therapy.

2. Cohort 2B, CAR-exposed (n=27): patients who have previously failed CD19 CAR-T cell therapy.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

• All B-ALL patients must have detectable disease by morphology, flow cytometry, cytogenetic analysis (e.g. polymerase chain reaction [PCR], fluorescence in situ hybridization [FISH], karyotyping) or imaging (e.g. positron emission tomography [PET]/computed tomography [CT]) or a high likelihood of active disease

• Refractory: failure to achieve complete response (CR) (minimal residual disease [MRD]-negative) at the end of induction

• Relapsed: recurrence of disease after achieving CR

• Evidence of CD19 expression by immunohistochemistry or flow cytometry on any prior or current tumor specimen or high likelihood of CD19 expression based on disease histology

CRITERIA FOR LEUKAPHERESIS AND PRE-THERAPY EVALUATION

• Screening evaluation appropriate for leukapheresis and T-cell collection

• Adequate vascular access available or planned for leukapheresis procedure (either peripheral line or surgically placed line)

• Documentation of CD19 expression on any prior or current tumor biopsy; patients who have received previous CD19-targeted therapy must have CD19-positive disease confirmed on a biopsy since completing the prior CD19-targeted therapy

• Internal review of histology

• Stage 2; cohort 2B (CAR-exposed) only:

• Relapsed disease after achieving CR in response to prior CD19-targeted nonhuJCAR014 CAR T-cell therapy OR

• Persistent disease after achieving PR to prior CD19-targeted non-huJCAR014 CAR T-cell therapy. Patients who are less than 3 months from prior CD19-targeted non-huJCAR014 CAR T-cell therapy must have persistent disease on biopsy or imaging (e.g. PET-CT or CT) evidence of disease progression

CRITERIA FOR LYMPHODEPLETING CHEMOTHERAPY AND huJCAR014 TREATMENT

• Successful collection of T cells for huJCAR014 manufacturing

• Detectable disease by imaging (for example PET +/- CT, magnetic resonance imaging [MRI]) and/or pathology evaluation

• Karnofsky performance status >= 60%

• Assessed by the investigator to have adequate bone marrow function to receive lymphodepleting conditioning chemotherapy

• Serum creatinine =< 1.5 x age-adjusted upper limit of normal (ULN) or calculated creatinine clearance (Cockcroft and Gault) > 30 mL/min/1.73 m^2

• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 5 x ULN and total bilirubin < 2.0 mg/dL unless due to malignancy or Gilbert's syndrome in the opinion of the principal investigator (PI) or designee

• Common Terminology Criteria for Adverse Events (CTCAE) grade =< 1 dyspnea and oxygen saturation (SaO2) >= 92% on room air

• Left ventricular ejection fraction (LVEF) >= 40% as assessed by echocardiogram (ECHO) or multiple uptake gated acquisition (MUGA) scan performed within 1 month before starting lymphodepleting chemotherapy

• Women of childbearing potential (defined as all women physiologically capable of becoming pregnant) must agree to both of the following:

• Use highly effective methods of contraception for at least 6 months after the last dose of huJCAR014, and

• Have a negative serum pregnancy test performed within 28 days before starting lymphodepleting chemotherapy

• Males who have partners of childbearing potential must agree to use an effective barrier contraceptive method for at least 6 months after the last dose of huJCAR014
