入选标准
- •For Cohort I Lymphoma, adults: Subject is ≥ 18 years of age at the time of signing the informed consent form (ICF).
- •For Cohort II ALL, pediatrics: Subject is ≥ 12 years of age at the time of signing ICF.
- •Patient or legal gurdian understand and voluntarily sign an informed consent document prior to any study related assessments/procedures.
- •Able to adhere to the study visit schedule and other protocol requirements as well as agrees to continued follow up for up to 15 years as mandated by the regulatory guidelines for gene therapy trials
- •CD19 or CD22 expression must be detected on the malignant cells by flow cytometry or immunohistochemistry. Results of previous assessments after the last treatment with CD19 targeted therapies but preceding inclusion of the patient in this trial are acceptable, if available.
- •Female Subject of childbearing potential and male subjects with female partner of childbearing potential is willing to use highly effective contraceptive methods during treatment until 12 months after IMP exposure. For the purpose of this document, a woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm apostmenopausal state in women not using hormonal contraception or hormonal replacement therapy. However in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. For the purpose of this document, a man is considered fertile after puberty unless permanently sterile by bilateral orchidectomy. Woman of childbearing potential (WOCBP) must also: - Have a negative pregnancy test as verified by the Investigator, one negative serum beta human chorionic gonadotropin (β-hCG) pregnancy test result at screening, prior to LD chemotherapy. This applies even if the subject practices true abstinence from heterosexual contact. - Perform pregnancy testing on a monthly basis for 12 months after IMP administration. A home test is sufficient. - Agree to abstain from breastfeeding during study participation and for at least 12 months after IMP administration. Male fertile subjects must also: Not donate sperm for at least 12 months following last MB-CART2219.1 infusion.
- •All subjects must agree to refrain from donating blood while on study drug and for 1 year after discontinuation from this study treatment.
- •Male or female patients must have relapsed refractory (r/r) CD19 or CD22 -expressing ALL or Lymphoma/CLL and meet the following disease-specific criteria:
- •Cohort I: Lymphoma (Richter’s Transformation /Burkitt-lymphoma/NHL/CLL), Adults ≥18 years of age: a. patients with r/r lymphoma with following entities according to 5th edtion of the WHO Classification of Haematolymphoid Tumours: -B-lymphoblastic lymphomas -B-Chronic lymphocytic leukemia -Splenic B-cell lymphoma -Marginal zone lymphoma -Follicular lymphoma -Mantle cell lymphoma -Large B-cell lymphoma -Burkitt lymphoma -Transformation from indolent lymphoma after two or more systemic therapies, including one approved in label CAR-T-cell or bispecific antibody treatment option or with contraindications for such treatments. b. patients with r/r CLL after established and approved treatment options including therapy with BTK-inhibitorshave failed. c. patients with lymphoma recommended for autologous or allogeneic stem cell transplant (SCT) therapy by interdisciplinary boards, but not consenting or ineligible for this treatment (including patients with refractory disease precluding alloSCT at this time, which can be included in the study as bridge to alloSCT). d. Patients with with lymphoma relapse after SCT, or after CD19 or CD22 targeting therapies and with confirmed either CD19 or CD22 expression after relapse. e. Patients with CNS involvement by lymphoma are eligible if disease is successfully controlled at the time of inclusion.
- •Cohort II: Acute B-lymphoplastic Leukemia (B-ALL), pediatric patients aged ≥ 12 – 17 years (only opened after substantial amendment and approval of DSMB and authorities upon analysis of dose escalation cohort I: e. Patients with second or later relapse of ALL with >5% blasts in BM or rising molecular failure on two separate measurements and without an approved option for in label CAR-T cells or bispecific or cytotoxic antibody treatment. f. Patients with relapse after SCT or other CD19 or CD22 targeted treatment with confirmed either CD19 or CD22 expression after relapse. g. Patients not consenting or ineligible for allogeneic SCT or have refractory disease activity precluding allogeneic SCT at this time, or h. Patients with Ph+ ALL if they are intolerant to tyrosine kinase inhibitor (TKI) therapy, or if they have r/r disease after treatment with at least 2 different TKIs, i. ALL patients with combined bone marrow and CNS and/or testicular relapse are eligible only if the extramedullary disease has been successfully controlled by conventional therapy at the time of inclusion (e.g. intrathecal chemotherapy, orchiectomy). j. Patients with ALL in hematologic remission after induction treatment, but ineligible for full execution of further standardly recommended treatments because of medical or other reasons.
