Обзор

FRONTIER is a prospective, single arm, open label, multi-center, Phase II study of MB-CART2019.1 (Zamtocabtagene Autoleucel) therapy as frontline consolidation for high-risk Mantle Cell Lymphoma (MCL) participants

Подробное описание

This is a prospective, single arm, open label, multi-center, Phase II study of MB-CART2019.1 (Zamtocabtagene Autoleucel) therapy as frontline consolidation for high-risk Mantle Cell Lymphoma participants. Participants will be enrolled on the study after diagnosis and before the end of their second cycle of induction therapy.

Eligible patients will receive a single intravenous infusion of MB-CART2019.1 cells at a dose of 2.5x10\^6 cells/kg following lymphodepleting chemotherapy. The goal is 52 participants in total who receive MB-CART2019.1 therapy. Additional participants may be screened, consented, registered, and treated in order to reach accrual goals. Participants will be followed on the trial for 1-year post-infusion. Assessment of survival annually through 15 years after infusion will be completed using the CIBMTR infrastructure.

• Subject should have a tumor biopsy sample (at least 5 unstained slides of tissue or tissue block) available prior to MB-CART2019.1 infusion, preferably collected pre-induction.
• If archival tissue is not available, the patient may be enrolled after discussion with the protocol chair and/or protocol officer

• Leptomeningeal Disease at diagnosis
• NOTCH1 mutation
• Received 2 cycles of appropriate systemic induction therapy, which includes a CD20 antibody +/- cytotoxic therapy +/- oral targeted therapy (e.g., BTKi, immunomodulatory imid drugs), with the following considerations:

• CD20 antibody alone does not count towards a cycle of treatment
• Induction cycles do not have to be identical
• For BTKis and/or lenalidomide a cycle is defined as 14-28 days and will be based on institutional treatment regimens.
• Intrathecal chemotherapy will not count towards a cycle of treatment
• Radiation therapy will not count towards a cycle of treatment
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 at screening. ECOG performance status of 2 at screening is allowed if the decrease in performance status is attributed to lymphoma
• Disease response assessment of either complete response, partial response, or stable disease by Lugano 2014 criteria assessed by 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) (preferred) or contrast enhanced CT scans including neck/chest/abdomen/pelvis \[37\] after 2 cycles of induction therapy. If the participant has history of CNS disease, then he/she must have no history of or active parenchymal disease on magnetic resonance imaging (MRI)

a. Leptomeningeal alone disease is allowable if it is not clinically progressive or worsening from baseline assessment

• A creatinine clearance (as estimated by direct urine collection, Chronic Kidney Disease Epidemiology Collaboration \[CKD-EPI\], or Cockcroft-Gault Equation or institutional standard) ≥ 45 mL/min
• Subjects of childbearing or child fathering potential must be willing to practice birth control from the time of enrollment on this study until the follow-up period of the study

Критерии исключения
