Study of CART Cell (MB-CART19.1) in Patients With Relapsed or Refractory CD19 Positive NHL

A Phase II Study of CART Cell (MB-CART19.1) in Patients With Relapsed or Refractory CD19 Positive NHL

Sponsor

King Hussein Cancer Center

Enrollment

26 participants

Start Date

Feb 12, 2025

Study Type

INTERVENTIONAL

Conditions

Non-Hodgkin Lymphoma Refractory/ Relapsed

Summary

This is a Prospective Single Center, open label, Non-randomized, Single Arm, Single Dose, Phase II Clinical Trial. Adult patients \>18-year-old with CD19+ Non-Hodgkin lymphoma are eligible for the study if they meet eligibility criteria. Patients will receive a fresh single dose of MB-CART-19.1 and will be followed for 12 months and evaluated for efficacy and safety.

Eligibility

Min Age: 18 YearsMax Age: 75 Years

Inclusion Criteria12

Eligible patients with a diagnosis of aggressive NHL:
Patients after progression on at least one standard chemotherapy and one salvage regimen or
Patients considered for alloSCT but are found ineligible or
Patients who have relapsed post alloSCT at least 100 days post-transplant, with no evidence of active GVHD, and no longer taking immunosuppressive agents for at least 30 days prior to enrollment.
Patients with CNS disease (excluding isolated CNS lymphoma) are eligible only if disease has been successfully cleared at the time of inclusion.
CD19 expression must be detected on the malignant cells by flow cytometry or immunohistochemistry
Age \> 18 year up to 75 years old (if deemed fit by treating investigator);
Baseline absolute CD3+ T cell count by FACS ≥100/µl;
ECOG performance score of 0-2 at screening;
No active Hepatitis B, Hepatitis C, HIV I/II
No childbearing potential or negative pregnancy test at screening within 7 days from starting lymphodepletion chemotherapy and before bridging chemotherapy in women with childbearing potential;
Signed and dated informed consent, before conduct of any trial-specific procedure.

Exclusion Criteria16

Residual CNS disease
Current autoimmune disease, or history of autoimmune disease with potential CNS involvement;
Active clinically significant CNS dysfunction (including but not limited to uncontrolled seizure disorders, cerebrovascular ischemia or hemorrhage, dementia, paralysis)
History of an additional malignancy other than non-melanoma skin cancer or carcinoma in situ unless disease free for ≥3 years;
Pulmonary function: Patients with pre-existing severe lung disease or DLCO of less than 50% or active pulmonary infiltrates on imaging studies.
Cardiac function: left ventricular ejection faction \<50% by echocardiogram,
Renal function: Creatinine clearance \<50 mL/min/1.73 m2, by Cockcroft-Gault formula (Cockcroft and Gault 1976) for patients ≥18 years.
Liver function: patients with serum bilirubin ≥3 times upper limit of or AST or ALT \> 5 times upper limit of normal, unless due to lymphoma liver infiltration in the estimation of the investigator.
Rapidly progressive disease that in the estimation of the investigator would compromise ability to complete study therapy;
Pregnant or breast-feeding females
Medications: systemic chemotherapies, corticosteroids with the exception of physiologic replacement dosing, Fludarabine/clofarabine or immunosuppressive (Calcineurin inhibitors) drugs and antibodies or investigational drugs or donor lymphocyte transfusions or radiation therapy within 30 days prior to apheresis, and rituximab within 2 weeks with the exception of Intrathecal chemotherapy is allowed prior to treatment, but should be discontinued 10 days prior to-CART19 infusion to limit the risk of neurotoxicities;
Patients of child-bearing or fathering potential not willing to practice an effective form of birth control from the time of enrollment and for three months after dosing of the CARTs;
Concurrent participation in another interventional trial that could interact with this trial, e.g. CAR T trials.
Other investigational treatment within 4 weeks before CARTs infusion;
Cerebral dysfunction, legal incapacity of adult patients;
Committal to an institution on judicial or official order.

Interventions

OTHERMB-CART-19.1

The leukapheresed product will be used for the individual manufacturing of MB-CART19.1 by using the automated closed CliniMACS Prodigy System. CD4+ and CD8+ T-cells will be selected, enriched and activated, followed by lentivirus-based transduction with the CD19 CAR construct. Then the MB-CART19.1 transduced T cells will be expanded and finally formulated.
