简要总结
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
详细描述
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.

入选标准
- •Diagnosis of MCL requires histologic confirmation by either overexpression of cyclin D1 OR presence of t(11;14) (q13; q32) translocation
- •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
- •High Risk Disease at diagnosis, defined as having at least ONE of the criteria below:
- •High risk MIPI-c (as calculated by https://www.european-mcl.net/home/scores-mipi-mipi-c-19.html)
- •Simplified MIPI high-risk ≥6.2
- •TP53 mutation OR ≥50% TP53 expression by IHC
- •Complex Karyotype [e.g. 3 or more cytogenetic abnormalities, excluding the presence or absence of t(11:14)]
- •Blastoid or pleomorphic histology with Ki-67 ≥30%
- •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
排除标准
- •Unable to give informed consent
- •Any disease progression that occurs during the first 2 induction cycles
- •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
- •Cardiac ejection fraction (EF) < 45% as determined by an echocardiogram (ECHO) or Multigated Radionuclide Acquisition scan (MUGA) (if range is provided, the upper value of the range may be used for assessing eligibility)
- •Resting O2 saturation < 92% on room air
- •Serum alanine aminotransferase (ALT) / aspartate aminotransferase (AST) ≥ 5 times the Upper Limit of Normal (ULN) for age
- •Total bilirubin >1.5 mg/dL, except in individuals with Gilbert's syndrome
- •Absolute neutrophil count (ANC) < 1000/μL unless related to bone marrow infiltration by mantle cell lymphoma. No short-acting granulocyte colony-stimulating factor (G-CSF) use within 7 days of ANC evaluation
- •Platelet count < 50,000/µL unless related to bone marrow infiltration or hypersplenism by mantle cell lymphoma. No transfusions within 7 days of assessment.
- •Absolute CD3 count < 50/μL at screening
- •Absolute lymphocyte count (ALC) < 100/μL within 7 days of apheresis
- •Known history of infection with human immunodeficiency virus (HIV)
- •Known active infection with hepatitis B (hepatitis B surface antigen [HBsAg] positive). If there is a history of treated hepatitis B, the viral load must be polymerase chain reaction (PCR) negative; antiviral prophylaxis is required if HBsAg negative and anti-hepatitis B core (HBc) positive
- •Known active infection with hepatitis C virus (anti-HCV antibody positive). If patient has a positive hepatitis C antibody, the viral load must be undetectable per quantitative PCR and/or nucleic acid testing
- •No seizure history within 6 months prior to enrollment
- •Known history of cerebral vascular accident (CVA) within prior 12 months
- •Known history or presence of autoimmune CNS disease, such as multiple sclerosis, optic neuritis or other immunologic /or inflammatory diseases
- •Presence of active CNS disorder that, in the judgment of the investigator, may impair the ability to evaluate neurotoxicity

- •a. Uncontrolled is defined as currently taking medication and with progression or no clinical improvement on adequate medical treatment
- •Pregnant or breast-feeding woman
- •Previous or concurrent malignancy with the following exceptions:
- •Adequately treated basal cell or squamous cell carcinoma (adequate wound healing is required prior to study entry)
