Miltenyi Biomedicine presents primary analysis of the pivotal DALY 2-EU trial for second-line relapsed/refractory large B-cell lymphoma at the 67th American Society of Hematology (ASH) Annual Meeting

• DALY 2-EU results show zamtocabtagene autoleucel (zamto-cel) demonstrated clinically meaningful superiority over chemoimmunotherapy in patients with relapsed/refractory large B-cell lymphoma (r/r LBCL)1
• Zamto-cel was well-tolerated in the majority of patients. DALY 2-EU included a high-risk study population, characterized by older age and clinically high-risk disease features
• A 12-day manufacturing time resulted in a vein-to-vein time of 14-16 days, reducing the likelihood for bridging therapy.

BERGISCH GLADBACH, Germany, Dec. 07, 2025 (GLOBE NEWSWIRE) -- Miltenyi Biomedicine today announced results from the pivotal DALY 2-EU trial evaluating the efficacy and safety of zamtocabtagene autoleucel (zamto-cel) compared with standard chemoimmunotherapy (R-GemOx or Pola-BR) in patients with second-line, relapsed or refractory large B-cell lymphoma (r/r LBCL) who were transplant-ineligible due to age, comorbidities, or other medical reasons.

The primary analysis showed that zamto-cel demonstrated significant and clinically meaningful superiority over chemoimmunotherapy (R-GemOx) in transplant-ineligible patients who were at a high risk of rapid disease progression.1 This study population was characterized by older age and clinically high-risk disease features: the median age was 74 years, 57% of patients had a high International Prognostic Index (IPI≥ 3) and 67% presented with stage III/IV disease. Zamto-cel was well tolerated in this predominantly older and high-risk population.1

Dr. Peter Borchmann, Lead investigator of DALY 2-EU trial and Assistant Medical Director in the Department of Hematology and Oncology at the University Hospital of Cologne, Germany, said: “Zamto-cel demonstrated clinically meaningful and statistically significant superiority over R-GemOx in transplant-ineligible patients with high-risk disease, improving event-free survival while maintaining a favorable tolerability profile. These findings highlight the potential of zamto-cel as an important new treatment option for a clinically vulnerable patient population with limited therapeutic choices.”

Dr. Toon Overstijns, Chief Executive Officer of Miltenyi Biomedicine, said: “The DALY 2-EU results mark an important milestone in our commitment to advancing cell and gene therapies. Zamto-cel - the first tandem CD20-CD19 (directed), non-cryopreserved CAR-T cell therapy - demonstrated meaningful clinical benefit with promising efficacy and safety, bringing us closer to providing much needed treatment options for patients with high-risk lymphomas.”

• Zamto-cel is the first tandem CD20-CD19 (directed) non-cryopreserved chimeric antigen receptor T (CAR-T) cell therapy. The main mechanisms for relapse after treatments with CD19-directed CAR-T cell therapies are the limited persistence of CAR-T cells, inhibition of CAR-T cell function, and CD19 immunological antigen escape. To minimize the risk of relapse due to CD19 antigen escape, zamto-cel utilizes dual antigen targeting of CD20 and CD19. Zamto-cel has a 12-day manufacturing time, resulting in a vein-to-vein time of 14-16 days and reducing the likelihood for bridging therapy

DALY 2-EU Primary results1

At the data cutoff, patients were randomly assigned to receive zamto-cel (n=82) or R-GemOx/ PolaBR (n=86). The trial allowed for crossover, 29 patients received zamto-cel following failure to achieve a response with either R-GemOx (n=28) or Pola-BR (n=1)

Efficacy Results (assessed by the blinded independent review committee (BIRC))

• The median event-free survival (EFS) for zamto-cel was 6.2 months (95% CI 3.8-13.8) compared to 2.5 months (95% CI 2.0-3.3) for R-GemOx (HR 0.39; 95% CI 0.27-0.58; p<0.0001).
• The median progression-free survival (PFS) was significantly longer with zamto-cel at 8.5 months (95% CI 3.8-16.8) versus 3.3 months (95% CI 2.0-3.8) for R-GemOx (HR 0.43 [95% CI 0.28-0.65]; p<0.0001).
• In the intent-to-treat (ITT) population, the overall response rate (ORR) was 72% with a 54% complete response rate (CRR) for zamto-cel compared to 45% ORR and 14% CRR for R-GemOx.

Safety Results1
Zamto-cel was well-tolerated in this elderly patient population with high risk

• Grade ≥ 3 cytokine release syndrome (CRS) was reported in 4 patients (5.3).
• Grade 3 Immune effector cell-associated neurotoxicity syndrome (ICANS) occurred in 1 patient (1.3%).

About DALY 2-EU2
DALY 2-EU (NCT04844866) is a pivotal, randomized, multi-center, open-label Phase II trial conducted in 12 countries within the EU, evaluating the safety and efficacy of genetically engineered autologous T-cells expressing anti-CD20 and anti-CD19 specific chimeric antigen receptor, zamtocabtagene autoleucel (zamto-cel), compared to chemoimmunotherapy (CIT), (rituximab, gemcitabine, and oxaliplatin (R.GemOx)) or polatuzumab vedotin plus bendamustine/rituximab (Pola-BR)), as a second-line therapy for primary relapsed/refractory large B-cell lymphoma (r/r LBCL). To our knowledge, is the only CAR-T randomized study in this patient population to date.

Eligible patients were adults with r/r LBCL who were refractory or relapsed within 24 months from the start of their first-line treatment, had received at least an anthracycline and a rituximab-containing regimen and were ineligible for a stem-cell transplant.

Participants were randomized 1:1 to receive either zamto-cel or CIT (R-GemOx/Pola-BR). Zamto-cel was administered as a single non-cryopreserved infusion at a dose of 2.5 x 10^6 CAR-transduced T cells per kg body weight after lymphodepletion with fludarabine and cyclophosphamide. Patients randomized to the comparator arm received either R-GemOx or Pola-BR.

The primary endpoint of the trial is event-free survival (EFS) assessed by a blinded independent review committee (BIRC), defined as the time from randomization to objective disease progression, failure to achieve a partial response (PR) or complete response (CR) at or beyond Week 8, leading to a new anti-lymphoma therapy or death from any cause. Secondary endpoints include progression-free survival (PFS), best complete response rate (CRR), duration of complete response (DOR), and overall survival (OS).

These data will be reported as part of a pre-planned EFS interim analysis after a median follow-up of 17 months. Additional analyses are planned with longer follow-up periods and will be presented at future meetings.

DALY 2-EU results join previous zamto-cel publications in other indications and populations, including:

• DALY II USA (NCT04792489), a multicenter, open label, single-arm Phase II trial of zamto-cel in patients with r/r DLBCL after at least two prior lines of treatment, including anti-CD20 monoclonal antibody and anthracycline-containing regimen and measurable disease per Lugano 2014 classification. The ORR in the evaluable patient population (n=59) as assessed by an Independent Radiology Committee was 72.9% (95% CI, 59.7-83.6) with a CRR of 49.2% (95% CI, 35.9-62.5).
• In the DALY II USA clinical trial, a dedicated cohort for r/r central nervous system lymphoma was opened. In this cohort of 16 patients, the data showed an overall response rate of 80% and 100% and a complete response rate of 50% and 100% in the PCNSL (primary CNS lymphoma) and SCNSL (secondary CNS lymphoma) respectively.
• Zamto-cel is being explored in r/r Mantle cell lymphoma (MCL) and r/r Richter's transformation (RT)

About zamtocabtagene autoleucel (zamto-cel)
Zamto-cel is an investigational autologous chimeric antigen receptor (CAR) T-cell therapy designed to target both CD20 and CD19. It is being studied in clinical trials for the treatment of relapsed or refractory B-cell malignancies, including large B-cell lymphoma (LBCL), diffuse large B-cell lymphoma (DLBCL), primary and secondary central nervous system (CNS) lymphoma, mantle cell lymphoma (MCL), Richter's transformation (RT), and other B-cell neoplasms.

Zamto-cel is manufactured using Miltenyi's proprietary platform, a closed, automated system. The manufacturing time of 12 days results in a vein-to-vein time of 14-16 days, reducing the need for bridging therapy and increasing the ability to receive cellular therapy for high risk patients with urgent therapeutic needs. Its non-cryopreserved formulation eliminates cryopreservation-related logistical steps and costs.
