DALY II USA/ MB-CART2019.1 for DLBCL

July 9, 2026 updated by: Miltenyi Biomedicine GmbH

A Multi-center Single Arm Phase II Study to Evaluate the Safety and Efficacy of Genetically Engineered Autologous Cells Expressing Anti-CD20 and Anti-CD19 Specific Chimeric Antigen Receptor in Subjects With Relapsed and/or Refractory Diffuse Large B Cell Lymphoma

DALY II USA is a phase II, multi-center, single arm study to evaluate the efficacy, safety, and pharmacokinetics of zamtocabtagene autoleucel (MB-CART2019.1) in patients with relapsed and/or refractory B cell lymphoma (BCL). Cohorts include subjects with diffuse large B-cell lymphoma (DLBCL) after receiving at least 2 lines of therapy, primary or secondary central nervous system (CNS) lymphoma (PCNSL) and (SCNSL) after receiving at least one line of therapy, mantle cell lymphoma (MCL) and Richter's transformation (RT) after receiving at least one line of therapy, and DLBCL transplant-ineligible after receiving at least one line of therapy.

Detailed Description

A prospective, single arm, open label, multi-center, phase II study of autologous T cells engineered against both CD19 and CD20 antigens for subjects with relapsed or refractory DLBCL after receiving at least two lines of therapy. The investigational agent is the MB-CART2019.1 cells. Additional cohorts include transplant-ineligible subjects with relapsed and/or refractory DLBCL after first-line therapy (i.e. DLBCL transplant-ineligible 2nd-line), r/r B-cell primary or secondary central nervous system (CNS) lymphoma (PCNSL) and (SCNSL), mantle cell lymphoma (MCL) and Richter's transformation (RT) after receiving at least one line of therapy. After successful screening, subjects will undergo leukapheresis to collect product for manufacturing. In preparation for the fresh product infusion, subjects will undergo a lymphodepleting regimen with cyclophosphamide and fludarabine, or bendamustine. Cell infusion will be administered intravenously at a dose of 2.5 x 106 CAR+ cells/kg body weight. The study will start with enrollment of 3 subjects in the lead-in safety phase, and after safety is evaluated, the study will continue with enrollment of the remaining subjects. Subjects will be followed for up to 2 years, for efficacy and safety outcomes as well as health-related quality of life (HRQol). Additional long-term follow-up will be conducted for participants under a separate long-term follow-up protocol.

In addition, all subjects must have:

  • Age ≥18 years

  • Eastern Cooperative Oncology Group (ECOG) performance status that is either 0 or 1 at screening. ECOG performance status of 2 at screen is allowed if the decrease in performance status is due to lymphoma

If medically not feasible to obtain a biopsy from the most recent relapse and for cases when the amount of tissue is limited, the sponsor should be consulted, to confirm adequacy of the sample for study required analyses

  • No clinical suspicion of central nervous system (CNS) lymphoma (not applicable to CNS cohort)

    • Subjects in DLBCL transplant-ineligible 2nd-line cohort with SCNSL will be allowed for inclusion
