About this study
Official title: 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.
Read the 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.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 57 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 13 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 32 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ron Gomez (617-218-0044, clinicaltrials@miltenyi.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Objective Response Rate (time frame: through study completion, up to 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2026.
