Genmab Presents Pivotal Phase 3 Data from EPCORE® FL-1 Trial Demonstrating Clinical Benefit of EPKINLY® (epcoritamab-bysp) in Combination with Rituximab and Lenalidomide (R2) in Patients with Relapsed or Refractory Follicular Lymphoma

On December 7, 2025 Genmab A/S (Nasdaq: GMAB) reported primary data from the pivotal Phase 3 EPCORE FL-1 study evaluating fixed duration EPKINLY (epcoritamab-bysp) in combination with rituximab and lenalidomide (EPKINLY + R2) in adult patients with relapsed or refractory (R/R) follicular lymphoma (FL). The study showed that treatment with EPKINLY + R2 reduced the risk of disease progression or death by 79% (HR 0.21, 95% CI: 0.14-0.31, p<0.0001) compared to standard of care R2. Additionally, the overall response rate (ORR) in patients treated with EPKINLY + R2 was 95% (95% CI: 91.5, 97.4) compared to 79% in patients treated with R2 (95% CI: 73.6, 84.1; P<.0001). The EPCORE FL-1 study results were presented during an oral presentation (abstract 466) at the 67th Annual Meeting and Exposition of the American Society of Hematology (ASH) (Free ASH Whitepaper) in Orlando, Florida, featured in the "Emerging Therapies and Immunotherapies in Blood Cancers" ASH (Free ASH Whitepaper) press briefing, and have been simultaneously published in The Lancet.

"Patients with relapsed or refractory follicular lymphoma have historically had limited treatment options," said Lorenzo Falchi, M.D., Lymphoma Specialist, Department of Medicine, Memorial Sloan Kettering Cancer Center. "The EPCORE FL-1 results demonstrate that epcoritamab plus R2 is the first bispecific antibody-based, chemotherapy-free combination to show superior clinical benefit over standard of care in a Phase 3 trial, underscoring its potential to redefine the second-line treatment landscape for follicular lymphoma."

The EPCORE FL-1 study included patients with R/R FL following at least one prior line of treatment across a broad range of patient characteristics and disease risk factors. Among patients who were treated with EPKINLY + R2 at the second planned interim analysis (median follow-up, 14.8 months), 83% achieved a complete response (CR) (n=201/243, 95% CI: 77.4, 87.3) compared to a 50% CR rate among patients treated with R2 (n=122/245, 95% CI: 43.4, 56.2). The 12-month duration of response (DOR) was 89% (95% CI: 83.6, 93.0) versus 49% (95% CI: 38.8, 57.5) for patients treated with EPKINLY + R2 and R2, respectively.

The safety profile of EPKINLY + R2 in the EPCORE FL-1 study was consistent with the known safety profiles of the individual regimens (epcoritamab and R2). Grade 3 or 4 treatment-emergent adverse events (TEAE) were reported in 90.1% of patients treated with EPKINLY + R2 compared to 67.6% of patients treated with R2, the difference being primarily driven by higher rates of Grade 3 or 4 neutropenia (68.7% vs. 42.0%) and infections (33.3% vs. 15.1%). Fatal TEAEs occurred in 1.6% of patients treated with EPKINLY + R2 compared to 3.8% patients treated with R2. TEAEs leading to discontinuation occurred in 18.9% and 12.2% of patients treated with EPKINLY + R2 and R2, respectively. With the three step-up dosing regimen, CRS events were low grade and occurred in 26.3% of patients (21.2% Grade 1, 5.3% Grade 2).

"The pivotal results from the EPCORE FL-1 trial demonstrate the potential of epcoritamab, in combination with established therapies, to enable earlier intervention across sites of care and deliver improved outcomes for patients with relapsed or refractory follicular lymphoma," said Dr. Judith Klimovsky, Executive Vice President and Chief Development Officer of Genmab. "We remain committed to developing epcoritamab, as a monotherapy and in combination, as a potential core therapy for B-cell malignancies and as a therapeutic innovation that can shift the treatment paradigm."

In November 2025, the U.S. Food and Drug Administration (FDA) approved the combination of EPKINLY + R2 for the treatment of patients with relapsed or refractory FL after one or more lines of systemic therapy. EPKINLY is also approved in the U.S. to treat adults with relapsed/refractory FL after two or more prior treatments.

About the EPCORE FL-1 Trial
EPCORE FL-1 (NCT05409066) is a Phase 3 open-label interventional trial to evaluate the safety and efficacy of epcoritamab plus rituximab and lenalidomide (R2) versus R2 alone in patients with relapsed/refractory (R/R) follicular lymphoma (FL). Patients were randomized to receive EPKINLY in combination with rituximab and lenalidomide (n=243) or rituximab and lenalidomide alone (n=245). Patients received EPKINLY in 28-day cycles for a total of 12 cycles or until disease progression or unacceptable toxicity, whichever occurred first. Efficacy was established based on the dual primary endpoints of progression free survival (PFS) and overall response rate (ORR) determined by Lugano 2014 criteria as assessed by Independent Review Committee (IRC). Additional efficacy outcome measures include complete response (CR) and duration of response (DOR).

About Follicular Lymphoma (FL)
Follicular lymphoma (FL) is typically an indolent, or slow-growing, form of non-Hodgkin lymphoma (NHL), that arises from B-lymphocytes. The second most common form of NHL, FL accounts for 20-30% of all NHL cases and is diagnosed in approximately 15,000 people in the U.S. every year.i,ii FL is considered incurable with current standard of care therapies.iii Patients often relapse, and with each relapse the remission and time to next treatment shorten.iv Over time, transformation to diffuse large B-cell lymphoma (DLBCL), an aggressive form of NHL associated with poor survival outcomes, can occur in more than 25% of FL patients.v

About Epcoritamab
Epcoritamab is an IgG1-bispecific antibody created using Genmab’s proprietary DuoBody technology and administered subcutaneously. Genmab’s DuoBody-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response toward target cell types. Epcoritamab is designed to simultaneously bind to CD3 on T cells and CD20 on B cells and induces T-cell-mediated killing of CD20+ cells.vi

Epcoritamab (approved under the brand name EPKINLY in the U.S. and Japan, and TEPKINLY in the EU) has received regulatory approval in certain lymphoma indications in several territories. Where approved, epcoritamab is a readily accessible therapy. Epcoritamab is being co-developed by Genmab and AbbVie as part of the companies’ oncology collaboration. The companies will share commercial responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization. Both companies will pursue additional international regulatory approvals for the investigational R/R FL indication and additional approvals for the R/R DLBCL indication.

Genmab and AbbVie continue to evaluate the use of epcoritamab as a monotherapy, and in combination, across lines of therapy in a range of hematologic malignancies. This includes four ongoing Phase 3, open-label, randomized trials, among them a trial evaluating epcoritamab as a monotherapy in patients with R/R DLBCL compared to investigators choice chemotherapy (NCT04628494), a trial evaluating epcoritamab in combination with R-CHOP in adult patients with newly diagnosed DLBCL (NCT05578976), a trial evaluating epcoritamab in combination with R2 compared to chemoimmunotherapy in patients with previously untreated FL (NCT06191744), and a trial evaluating epcoritamab in combination with lenalidomide compared to chemotherapy infusion in patients with R/R DLBCL (NCT06508658). The safety and efficacy of epcoritamab has not been established for these investigational uses. Please visit www.clinicaltrials.gov for more information.

The ASH (Free ASH Whitepaper) 2025 dataset builds on the promising efficacy signals previously shared at ASCO (Free ASCO Whitepaper) [2] 2025, highlighting rapid, deep, and durable responses with a favorable safety profile and encouraging early overall survival. Notably, responses were strongest at the 10mg ICT01 dose, which has now been endorsed by the FDA for further development. In 2025, ICT01 also received Orphan Drug Designation from both the FDA[3] and EMA.

"ICT01 continues to demonstrate rapid and durable responses across AML subtypes. The updated ASH (Free ASH Whitepaper) data further strengthens our confidence in ICT01’s ability, when added to Aza-Ven, to deliver deep, lasting remissions that have the potential to translate into meaningful overall survival improvement for patients" said Stephan Braun, MD, PhD, Chief Medical Officer of ImCheck Therapeutics. "We see an early onset of complete remissions, consistently strong efficacy at the selected dose across molecular subtypes, and signs of durable responses even in adverse-risk patients. These findings together with the encouraging early survival signal create a compelling case as we advance toward late-stage development."

Key Highlights:
Patient population: At the data cut-off on October 6, 2025, 57 patients aged 51 to 87 had been enrolled. Of these, 41 received 10 mg ICT01 and 16 received 75 mg ICT01, each in combination with Aza-Ven.
Rapid responses: More than 90% of patients treated with ICT01 (10 mg) achieved CRc4 as their best response already by end of Cycle 2.
Broad molecular activity: The 10 mg dose selected for future studies produced higher CR/CRc rates across molecular subtypes, including favorable-, intermediate-, and adverse-risk AML (e.g., TP53-mutated) versus the 75 mg dose.
Durability emerging: At a median follow-up of 10.8 months median DoR[5] was not yet reached for the 10 mg ICT01 dose.
Early survival signal: A 12-month OS[6] rate of 62% was observed, which is numerically higher than the ~54% reported for the Aza-Ven regimen in recent Phase 3 trials.
Favorable benefit–risk profile: Safety of the novel triplet regimen ICT01-Aza-Ven remains well manageable, with a 30-day mortality rate of 4%, and no deaths attributed to ICT01.
Regulatory momentum: ICT01 received Orphan Drug Designation from both FDA and EMA. The 10 mg ICT01 dose has been endorsed by FDA for further clinical development of the triplet regimen.
"ImCheck has in hand the alignment of strong clinical activity, a favorable safety profile, Orphan Drug Designations on both sides of the Atlantic, and now a clear regulatory-endorsed dose for ICT01 for accelerated late-stage development," added Pierre d’Epenoux, Chief Executive Officer of ImCheck Therapeutics. "These results arrive at a transformative moment for ImCheck, following the announced acquisition agreement with Ipsen. We remain deeply grateful to the patients, investigators, and our team for bringing ICT01 to this important inflection point."

"In the larger patient set Phase 2 results presented today at ASH (Free ASH Whitepaper), we are thrilled to see complete response rates continue to improve in NEXICART-2. These excellent results demonstrate the potential of NXC-201 to address the significant unmet medical need in relapsed/refractory AL Amyloidosis," said Ilya Rachman, MD, PhD, Chief Executive Officer of Immix Biopharma. Gabriel Morris, Chief Financial Officer of Immix Biopharma, added, "This exciting Phase 2 milestone brings us one step closer to delivering this promising therapy to patients upon planned BLA submission in 2026."

ASH Presentation Results – Phase 2

Prior to NXC-201 treatment, all patients were exposed to an anti-CD38 antibody and a proteasome inhibitor. Median prior lines of therapy was 4 (range: 1-10). All patients had baseline relapsed/refractory AL Amyloidosis organ involvement. After NXC-201 treatment, complete responses (CRs) were observed in 75% (15 out of 20 patients) (at s/u IFE(-) level) by independent review committee. In four out of five pending patients, minimum residual disease (MRD) negativity in bone marrow predicts future complete response, potentially increasing the future CR rate to 95%. Downstream clinical improvement, including organ responses, were observed in 70% of evaluable patients (7/10). No neurotoxicity was observed. Only low-grade cytokine release syndrome has been observed with a median duration of 1 day. The ASH (Free ASH Whitepaper) presentation contains clinical data as of November 13, 2025.

Current treatments typically result in a 10% or lower complete response (CR) rate in relapsed/refractory AL Amyloidosis according to Zanwar, et al 2024, indicating a high unmet medical need.

KOL Event Discussing NXC-201 ASH (Free ASH Whitepaper) 2025 Oral Presentation of Phase 2 Clinical Results

A Key Opinion Leader (KOL) event with lead investigator Heather Landau, MD, of Memorial Sloan Kettering Cancer Center, Shahzad Raza, MD, of Cleveland Clinic, and Vaishali Sanchorawala, MD, of Boston Medical Center will be held Sunday, December 7, 2025 8:00pm ET to discuss the significance of the NEXICART-2 Phase 2 Clinical Results.

About NEXICART-2
NEXICART-2 (NCT06097832) is an ongoing multi-site U.S. Phase 2 clinical trial of sterically-optimized CAR-T NXC-201 in relapsed/refractory AL Amyloidosis, with a registrational design. NEXICART-2 is expected to enroll 40 patients.

About NXC-201
NXC-201 is a sterically-optimized BCMA-targeted chimeric antigen receptor T (CAR-T) cell therapy with a "digital filter" that is designed to filter out non-specific activation. NXC-201 teaches the immune system to recognize and eliminate the source of the toxic light chains. NXC-201 has been awarded Regenerative Medicine Advanced Therapy (RMAT) by the FDA, and Orphan Drug Designation (ODD) by the US FDA and in the EU by the EMA.

About AL Amyloidosis
AL amyloidosis is a devastating disease where the immune system, that’s supposed to protect, instead continuously produces toxic light chains, clogging up the heart, kidney and liver, causing organ failure and death.

The number of patients in the U.S. with relapsed/refractory AL Amyloidosis is estimated to be growing at 12% per year according to Staron, et al Blood Cancer Journal, to approximately 38,500 patients in 2026.

The Amyloidosis market was $3.6 billion in 2017, and is expected to reach $6 billion in 2025, according to Grand View Research.

Lyell Immunopharma Presents New Clinical Data from Ongoing Trial of Ronde-Cel Showing High Rates of Durable Complete Responses in Patients with Large B-cell Lymphoma at the 67th ASH Annual Meeting and Exposition

On December 7, 2025 Lyell Immunopharma, Inc. (Nasdaq: LYEL), a clinical-stage company advancing a pipeline of next-generation chimeric antigen receptor (CAR) T-cell therapies for patients with cancer, reported new clinical and translational data from the ongoing clinical trial of rondecabtagene autoleucel (ronde-cel, also known as LYL314) in patients with large B-cell lymphoma (LBCL), which were presented today in two oral presentations at the 67th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition. As of the data cutoff date of September 5, 2025, ronde-cel continued to demonstrate robust clinical responses with a manageable safety profile appropriate for outpatient administration. A 93% overall response rate, a 76% complete response rate, and median progression-free survival of 18 months were reported for patients with relapsed and/or refractory (R/R) LBCL in the third- or later-line (3L+) setting. Patients evaluated in the second-line (2L) setting (94% with difficult-to-treat primary refractory disease) achieved an 83% overall response rate and a 61% complete response rate, and 70% of patients with a complete response remained in complete response at 6 months or longer.

Ronde-cel is an autologous dual-targeting CD19/CD20 CAR T-cell product candidate in pivotal development for patients with R/R LBCL. Ronde-cel CAR T cells are designed to have enhanced antitumor activity through a proprietary manufacturing process that enriches for CD62L-positive cells to produce a CAR T-cell product with a higher proportion of naïve and central memory T cells. The United States Food and Drug Administration (FDA) has granted ronde-cel Regenerative Medicine Advanced Therapy (RMAT) designation for the treatment of patients with R/R LBCL in the 3L+ and 2L settings.

"These data from the ongoing clinical trial showing high rates of durable complete responses along with a manageable safety profile in patients with high-risk large B-cell lymphoma represent the potential of ronde-cel to improve patient outcomes," commented Sarah M. Larson, MD, Associate Professor, Department of Medicine, Medical Director, Immune Effector Cell Therapy Program, Division of Hematology/Oncology, David Geffen School of Medicine at UCLA. "The two pivotal trials underway, including the first-of-its kind head-to-head CAR T-cell trial, are expected to provide a comprehensive and robust evaluation of the potential for ronde-cel to demonstrate differentiated benefit over approved CD19 CAR T-cell therapies."

Sixty-nine CAR T-cell naïve patients with R/R LBCL received ronde-cel as of the data cutoff date for the presentation. The efficacy evaluable population, defined as those patients with Day 84 assessments or prior disease progression or death, consisted of 47 patients (29 in the 3L+ and 18 in the 2L settings). Imaging assessments were performed locally by the sites. Patient demographics and baseline disease characteristics were consistent with a high-risk, heavily pre-treated patient population, particularly as compared to historical trials of CD19 CAR T-cell products: median ages of 64 and 65 years with 20% (9/45) and 21% (5/24) of patients being 75 years or older in the 3L+ and 2L settings, respectively; and primary refractory disease in 49% (22/45) and 92% (22/24) of patients in the 3L+ and 2L settings, respectively.

Patients Evaluated in the 3L+ Setting

There were 29 efficacy-evaluable 3L+ patients with R/R LBCL (diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, Grade 3B follicular lymphoma, or transformed follicular lymphoma) with a median follow up time of 12 months as of the data cutoff date. In these patients:

The overall response rate was 93% (27/29 patients), with 76% (22/29) of patients achieving a complete response
72% (13/18) of patients with complete response remained in complete response at 6 months or longer
Median progression-free survival was 18 months
Patients Evaluated in the 2L Setting

There were 18 efficacy-evaluable patients enrolled in the 2L setting with a median follow-up time of 9 months as of the data cutoff date. Of these efficacy-evaluable patients, 94% had primary refractory disease. In these patients:

The overall response rate was 83% (15/18 patients), with 61% (11/18) achieving a complete response
70% (7/10) of patients with complete response remained in complete response at 6 months or longer
The median duration of complete response was not reached
Safety Data

In 69 patients, including patients from both the 3L+ and the 2L cohorts, a manageable safety profile appropriate for outpatient administration was observed. No Grade 3 or greater cytokine release syndrome (CRS) was observed in any patient. Twenty-five of the 69 patients received protocol-directed dexamethasone prophylaxis (10 mg/day for 3 days). One case (4%) of Grade 3 or greater ICANS was reported in a patient with high disease burden; no case of Grade 2 ICANS was reported.

In all 69 patients, as of the data cutoff date, low rates of Grade 1 (32%) or Grade 2 (29%) CRS were reported; ICANS rates were reported as follows: Grade 1 (9%), Grade 2 (3%), and Grade 3 or greater (12%) of patients. The median time to complete resolution of all reports of ICANS was 4 days. Cell pharmacodynamic data demonstrated robust CAR T-cell expansion and persistence that were similar in patients with or without dexamethasone prophylaxis. No deaths were determined to be related to ronde-cel administration.

Pivotal Clinical Trials

Lyell has initiated two pivotal clinical trials of ronde-cel: PiNACLE – H2H and PiNACLE.

PiNACLE – H2H is a Phase 3 head-to-head CAR T-cell therapy randomized controlled clinical trial of ronde-cel versus investigator’s choice of either lisocabtagene maraleucel (liso-cel) or axicabtagene ciloleucel (axi-cel) in patients with R/R LBCL receiving treatment in the 2L setting. Patients randomized to ronde-cel will be treated with a dose of 100 x 106 CAR T cells; patients in the control arm will be treated as per the product label. The primary endpoint of the trial is event-free survival and the trial is expected to enroll approximately 200 patients per arm (N = 400) with R/R LBCL, including diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, high grade B-cell lymphoma, Grade 3B follicular lymphoma, or transformed follicular or transformed mantle cell lymphoma who have not previously received CAR T-cell therapy. Patients may be treated with ronde-cel in either the inpatient or outpatient setting. More information about the PiNACLE – H2H trial can be found on clinicaltrials.gov (NCT07188558) here.

PiNACLE is a single-arm trial of ronde-cel that is enrolling up to 120 patients receiving treatment in the 3L+ setting. This registration trial is a seamless expansion of the 3L+ cohort from the Phase 1/2 trial. The dose is 100 x 106 CAR+ cells and the primary endpoint is overall response rate. Patients may be treated with ronde-cel in either the inpatient or outpatient setting. More information about the PiNACLE trial can be found on clinicaltrials.gov (NCT05826535) here.

Ronde-cel Translational Data

Translational data from the ongoing Phase 1/2 clinical trial showed that ronde-cel manufactured with CD62L enrichment achieved robust expansion and high expression of memory-related genes after infusion in patients with LBCL. An evaluation of ronde-cel and published data for CD19 CAR T-cell products demonstrated that ronde-cel had a higher proportion of CD62L-positive T cells with a higher proportion of memory-cell phenotype prior to infusion (ronde-cel, N = 34; axi-cel, N = 110 and tisagenlecleucel (tisa-cel), N = 31). In addition, ronde-cel had up to a three-fold higher expansion in patients after infusion compared to the expansion of approved CD19 CAR T-cell products. The product memory-cell phenotype was positively correlated with expansion. Peripheral blood samples collected from patients one month after infusion (N = 9) also had a higher proportion of CAR T cells with a memory phenotype compared to cells from axi-cel-treated patients (N = 4). Ronde-cel CAR-positive T cells collected from patients one (N = 7) and two months (N = 3) after infusion demonstrated sustained capacity to proliferate, kill tumor cells over 72 hours, and secrete cytokines (N = 3).

About Rondecabtagene Autoleucel (Ronde-cel)

Rondecabtagene autoleucel (ronde-cel, also known as LYL314) is a next-generation dual-targeting CD19/CD20 CAR T-cell product candidate designed to increase complete response rates and prolong the duration of the responses as compared to the approved CD19 targeted CAR T-cell therapies for the treatment of R/R LBCL.

Ronde-cel is designed with an ‘OR’ logic gate to target B cells that express either CD19, CD20 or both, each with full potency. Ronde-cel is manufactured to produce a CAR T-cell product with higher proportions of naïve and central memory T cells through a proprietary process that enriches for CD62L-expressing cells. This manufacturing process is designed to generate CAR T cells with enhanced antitumor activity.

Ronde-cel has received RMAT designation from the FDA for the treatment of patients with R/R LBCL in the 3L+ and 2L settings, as well as Fast Track Designation for the treatment of patients with R/R LBCL in the 3L+ setting.
