Epcoritamab

Epcoritamab-bysp, sold under the brand name EPKINLY in the US and Japan and TEPKINLY in the EU, is a subcutaneously administered, humanized IgG1-bispecific monoclonal antibody that simultaneously binds to CD20 on the surface of B cells, including malignant cells, and CD3 on T cells, thereby facilitating T-cell activation and directed cytotoxicity against CD20-positive lymphoma cells.^[1] Developed by Genmab using their proprietary DuoBody® technology in collaboration with AbbVie, it represents a novel class of bispecific T-cell engagers (BiTEs) designed for targeted immunotherapy in B-cell malignancies.^[1]^[2] The U.S. Food and Drug Administration (FDA) first granted accelerated approval to epcoritamab-bysp on May 19, 2023, for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, or high-grade B-cell lymphoma after at least two prior lines of systemic therapy.^[3] This approval was based on clinical trial data demonstrating an overall response rate of 61% in the pivotal EPCORE NHL-1 study, with 38% achieving complete responses.^[3] On June 26, 2024, the FDA expanded accelerated approval to include adult patients with relapsed or refractory follicular lymphoma (FL) after two or more prior lines of systemic therapy, supported by an 82% overall response rate and 60% complete response rate from the same trial cohort.^[4]^[4] It has also received approvals from the European Medicines Agency (EMA) and Japan's Ministry of Health, Labour and Welfare (MHLW) for similar indications in relapsed or refractory B-cell lymphomas.^[5]^[6] Epcoritamab's dosing regimen involves weekly subcutaneous injections in 28-day cycles, with step-up dosing in cycle 1 to mitigate cytokine release syndrome (CRS), a key boxed warning alongside immune effector cell-associated neurotoxicity syndrome (ICANS).^[7] Clinical studies have shown durable responses in heavily pretreated patients, positioning it as a chemotherapy-free option in third-line and later settings for aggressive non-Hodgkin lymphomas such as DLBCL and high-grade B-cell lymphoma, as well as indolent follicular lymphoma.^[8] Ongoing research explores its potential in earlier lines of therapy and combination regimens to further improve outcomes in B-cell malignancies, including positive results from the Phase 3 EPCORE FL-1 trial of epcoritamab plus rituximab and lenalidomide in relapsed/refractory FL as of August 2025, with an FDA target action date of November 30, 2025.^[9]^[10]

Medical uses

Indications

Epcoritamab is indicated for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS), including DLBCL arising from indolent lymphoma and high-grade B-cell lymphoma, after two or more lines of systemic therapy.^[11] This approval, granted under accelerated approval by the FDA in May 2023, is based on response rates and durability of response from the EPCORE NHL-1 trial, where the overall response rate (ORR) was 61% and the complete response (CR) rate was 38% among 148 evaluable patients.^[11] The indication was expanded in June 2024 to include adult patients with relapsed or refractory follicular lymphoma (FL) after two or more lines of systemic therapy.^[7] In the FL cohort of the EPCORE NHL-1 trial, epcoritamab monotherapy yielded an ORR of 82% and a CR rate of 60% in 127 patients, supporting this accelerated approval.^[7] Epcoritamab is under investigation for earlier-line treatment in DLBCL, including frontline combinations with regimens like R-CHOP,^[12] as well as in combination with rituximab and lenalidomide for relapsed or refractory FL.^[13] Ongoing trials are also evaluating its use in other B-cell malignancies, such as chronic lymphocytic leukemia (CLL), particularly in relapsed or refractory settings with high-risk features.^[14] In August 2025, the phase 3 EPCORE FL-1 trial met its dual primary endpoints of progression-free survival for epcoritamab plus rituximab and lenalidomide versus rituximab and lenalidomide alone in relapsed or refractory FL; a supplemental new drug application has been submitted to the FDA, with a target action date of November 30, 2025.^[10] These investigational applications leverage epcoritamab's mechanism of targeting CD20-positive B cells to potentially broaden its role in B-cell non-Hodgkin lymphoma management.

Dosage and administration

Epcoritamab is administered exclusively via subcutaneous injection by a qualified healthcare professional in a setting equipped to manage severe reactions such as cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS).^[7] Patients should be well-hydrated prior to each dose, and certain lower doses (0.16 mg and 0.8 mg) require dilution using either the vial or syringe method with 0.9% sodium chloride injection to achieve the appropriate concentration, while 3 mg and 48 mg doses are administered undiluted.^[7] Injection sites should be rotated weekly during cycles 1 through 3, typically in the lower abdomen or thigh, avoiding areas with tattoos, scars, or inflammation.^[7] The recommended dosing regimen follows a step-up schedule in 28-day cycles to minimize CRS risk, continuing until disease progression or unacceptable toxicity. For relapsed or refractory diffuse large B-cell lymphoma (DLBCL) or high-grade B-cell lymphoma after at least two prior systemic therapies, a two-step up approach is used in cycle 1: 0.16 mg on day 1, 0.8 mg on day 8, and 48 mg on days 15 and 22.^[7] This is followed by 48 mg weekly (days 1, 8, 15, and 22) in cycles 2 and 3, biweekly (days 1 and 15) in cycles 4 through 9, and monthly (day 1) starting from cycle 10.^[7] For relapsed or refractory follicular lymphoma (FL) after at least two prior systemic therapies, a three-step up schedule applies in cycle 1: 0.16 mg on day 1, 0.8 mg on day 8, 3 mg on day 15, and 48 mg on day 22, with subsequent cycles mirroring the DLBCL maintenance schedule.^[7]

Cycle	Day 1	Day 8	Day 15	Day 22
DLBCL/High-grade B-cell Lymphoma (2-Step Up)
Cycle 1	0.16 mg	0.8 mg	48 mg	48 mg
Cycles 2–3	48 mg	48 mg	48 mg	48 mg
Cycles 4–9	48 mg	-	48 mg	-
Cycle 10+	48 mg	-	-	-
FL (3-Step Up)
Cycle 1	0.16 mg	0.8 mg	3 mg	48 mg
Cycles 2–3	48 mg	48 mg	48 mg	48 mg
Cycles 4–9	48 mg	-	48 mg	-
Cycle 10+	48 mg	-	-	-

Premedication is required before each cycle 1 dose to mitigate CRS, consisting of a corticosteroid (e.g., dexamethasone 15 mg oral or IV, or prednisolone 100 mg equivalent), an antihistamine (e.g., diphenhydramine 50 mg oral or IV), and an antipyretic (e.g., acetaminophen 650–1,000 mg oral), administered 30–120 minutes prior and continued for three days post-dose.^[7] In cycles 2 and beyond, premedication with corticosteroid alone is recommended for patients with prior grade 2 or 3 CRS, until no such events recur.^[7] Prophylaxis against Pneumocystis jirovecii pneumonia is mandatory starting before treatment, with herpes virus prophylaxis considered to prevent reactivation.^[7] Monitoring includes observation for CRS and ICANS signs and symptoms after each dose, with hospitalization required for 24 hours following the cycle 1 day 15 dose of 48 mg in DLBCL or high-grade B-cell lymphoma patients.^[7] If dosing is delayed beyond specified intervals (e.g., >8 days after 0.16 mg, >14 days after 0.8 mg, or >6 weeks after 48 mg), the step-up schedule must be repeated from the beginning of cycle 1, accompanied by premedication and monitoring.^[7] Dose modifications are guided by adverse reaction severity. For CRS, withhold epcoritamab for grade 1 (fever ≥100.4°F/38°C) until resolution, then resume with premedication; for grade 2 (hypotension or hypoxia), withhold and hospitalize if needed, resuming after resolution with enhanced premedication; permanently discontinue for grade 4 (life-threatening) or recurrent grade 3 (vasopressors or high-flow oxygen required).^[7] For ICANS, withhold for grade 1 (mild symptoms), administer dexamethasone 10 mg IV every 6 hours for grade 2, and permanently discontinue for grade 4 (coma or life-threatening) or recurrent grade 3; all cases require neurology consultation.^[7] Other toxicities, such as infections, neutropenia (ANC <0.5 × 10⁹/L), or thrombocytopenia (platelets <50 × 10⁹/L), necessitate withholding until resolution to grade 1 or baseline, with permanent discontinuation considered for grade 4 infections or recurrent severe events.^[7] Supportive care, including intensive interventions, is essential for severe reactions.^[7]

Mechanism of action

Binding and activation

Epcoritamab is a humanized IgG1 bispecific antibody engineered using Genmab's DuoBody® technology, which employs controlled Fab-arm exchange to generate a molecule with one Fab arm binding CD20 on B cells and the other binding CD3 on T cells.^[15] The antibody has a molecular weight of approximately 149 kDa and features a silenced Fc region through point mutations (L234F, L235E, D265A), which abrogate binding to Fcγ receptors and complement protein C1q while preserving interaction with the neonatal Fc receptor (FcRn) for pharmacokinetic stability.^[15]^[16] This 1:1 binding format enables targeted immune redirection without relying on Fc-mediated effector functions.^[17] The CD20-binding arm exhibits high affinity for the CD20 antigen, a transmembrane protein expressed on malignant and normal B cells, with an EC₅₀ of 10.40 nM observed on Daudi Burkitt's lymphoma cells.^[15] This binding targets a specific extracellular epitope on CD20 and occurs independently of Fc receptor engagement due to the engineered Fc silencing, ensuring that the primary mechanism relies on bispecific T-cell redirection rather than antibody-dependent cellular cytotoxicity or complement-dependent cytotoxicity.^[15]^[16] Epcoritamab shows cross-reactivity with cynomolgus monkey CD20 (EC₅₀ ≈ 2.80 nM) but not with CD20 from rodents or other non-primate species, supporting its preclinical evaluation in non-human primates.^[16] The CD3-binding arm targets the CD3ε subunit of the T-cell receptor complex, with an EC₅₀ of 4.73 nM on human T cells and a dissociation constant (K_D) of 12.5 nM for soluble human CD3ε.^[15] This affinity is tuned to be moderate relative to the CD20 arm, promoting avidity-driven enhancement upon dual engagement and thereby minimizing basal T-cell activation in the absence of target cells.^[17] Epcoritamab demonstrates comparable binding to cynomolgus CD3 (K_D ≈ 1.8 nM), facilitating cross-species pharmacology studies.^[16] Activation of the bispecific antibody is conditional, requiring simultaneous binding to CD20 on B cells and CD3 on T cells to form an immunological synapse that stabilizes the interaction and triggers downstream T-cell responses.^[15] This design feature—leveraging the asymmetric affinities and the need for target-mediated crosslinking—reduces off-target T-cell stimulation and cytokine release in the absence of CD20-positive cells, enhancing the therapeutic window.^[16]^[17] No cytotoxicity or significant T-cell activation occurs without CD20 engagement, underscoring the specificity of this binding-dependent mechanism.^[15]

T-cell engagement

Epcoritamab engages T cells by simultaneously binding to CD20 on malignant B cells and CD3 on T cells, thereby bridging these cells and forming an immunological synapse that redirects T-cell cytotoxicity toward CD20-positive targets.^[11]^[17] This synapse formation activates T cells independently of major histocompatibility complex presentation, enabling potent and selective killing of target cells in preclinical models.^[18] The cytotoxic activity induced by epcoritamab involves multiple T-cell-mediated pathways, including the release of perforin and granzymes, which perforate the target cell membrane and induce apoptosis, as well as Fas/FasL signaling that triggers programmed cell death in CD20-positive B cells.^[8] Additionally, activated T cells produce proinflammatory cytokines such as IFN-γ and TNF-α, which amplify the immune response and contribute to tumor cell elimination.^[19]^[17] This engagement leads to rapid and profound depletion of CD20-positive B cells across multiple compartments, including blood, bone marrow, and lymph nodes, as demonstrated in patient-derived samples and non-human primate models where sustained B-cell elimination was observed.^[17]^[19] Epcoritamab's specificity ensures that only CD20-expressing cells are targeted, sparing other immune cell populations, and it retains efficacy even against cells with low CD20 expression levels, with cytotoxicity showing no strong correlation to antigen density in preclinical assays.^[11]^[17]

Adverse effects

Cytokine release syndrome

Cytokine release syndrome (CRS) is a systemic inflammatory response resulting from T-cell activation induced by epcoritamab's bispecific engagement mechanism.^[7] It manifests as a potentially serious or life-threatening adverse effect, primarily due to rapid immune activation following administration.^[7] CRS occurs in up to 65% of patients treated with epcoritamab, with the majority of events classified as low-grade (grade 1 or 2) and typically onsetting within 24 hours of dosing.^[20] Symptoms include fever, chills, hypotension, hypoxia, dyspnea, tachycardia, and, in severe cases, organ dysfunction; the risk is highest with initial doses due to heightened T-cell response.^[7] The pathophysiology involves a massive release of pro-inflammatory cytokines, such as interleukin-6 (IL-6), interleukin-10 (IL-10), and interferon-gamma (IFN-γ), from activated T cells and subsequently recruited macrophages, amplifying the inflammatory cascade.^[21] CRS is graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) 2019 criteria, ranging from grade 1 (mild symptoms) to grade 4 (life-threatening).^[7] Management entails prompt recognition and supportive care; for grade 2 or higher, tocilizumab (an IL-6 receptor antagonist) is administered, with additional corticosteroids if needed, while grade 3 or higher events require hospitalization and potential treatment withholding.^[7] Premedication with dexamethasone and step-up dosing (starting with lower doses of 0.16 mg and 0.8 mg before the full 48 mg) help mitigate severity, particularly in cycle 1.^[7] In later treatment cycles, new CRS events are uncommon, with most (over 90%) occurring in cycle 1; recurrence has been reported in approximately 16% of patients.^[22] Recent 2025 studies have emphasized step-up dosing combined with outpatient monitoring protocols, achieving CRS rates as low as 40% overall while enabling most patients (over 90%) to receive treatment outside hospital settings without treatment discontinuation.^[23] Epcoritamab treatment, through its induction of profound B-cell depletion, increases the risk of infections by impairing humoral immunity, leading to susceptibility to bacterial, viral (such as herpesviruses), and fungal pathogens.^[7] In the pivotal EPCORE NHL-1 trial, serious infections occurred in 15% of patients with relapsed or refractory large B-cell lymphoma (LBCL) and 40% in those with follicular lymphoma (FL), with grade 3 or higher infections reported in approximately 20-25% across bispecific antibody studies including epcoritamab.^[7]^[24] Common examples include pneumonia, sepsis, and COVID-19, with fatal infections occurring in about 3% of treated patients.^[7]^[24] Prophylaxis against Pneumocystis jirovecii pneumonia (PJP) is recommended, and herpesvirus prophylaxis may be considered based on risk factors.^[7] Immune effector cell-associated neurotoxicity syndrome (ICANS), a potentially serious immune-related effect linked to cytokine-mediated central nervous system inflammation, has been observed in 6% of epcoritamab-treated patients in the EPCORE NHL-1 trial, with grade 3 or higher cases in about 1%.^[7]^[24] Symptoms may include confusion, seizures, and aphasia, typically emerging after a median of 7 days (range, 1-379 days) in patients with LBCL or 16 days (range, 1-288 days) in patients with FL, and resolving in most cases with supportive care and corticosteroids.^[7] Monitoring for neurological changes is essential, particularly in the first weeks of treatment.^[7] Prolonged hypogammaglobulinemia, resulting from sustained B-cell aplasia, develops in a subset of patients, with immunoglobulin G levels decreasing by a median of approximately 20% during therapy and requiring intravenous immunoglobulin (IVIG) replacement in up to 34% of cases in some studies to prevent recurrent infections.^[25]^[26] This immune disruption underscores the need for ongoing assessment of immunoglobulin levels and infection surveillance.^[27] Due to B-cell depletion, live vaccines are contraindicated during and for at least 4 weeks prior to epcoritamab initiation, while inactivated vaccines are recommended before starting treatment, though their efficacy may be reduced post-depletion.^[28] Household contacts should maintain up-to-date vaccinations, including live ones, to minimize exposure risks.^[29]

Other common adverse effects

Common adverse effects of epcoritamab, observed in clinical trials such as EPCORE NHL-1, primarily include hematologic toxicities, gastrointestinal disturbances, musculoskeletal symptoms, and laboratory abnormalities, most of which are mild to moderate (grade 1-2) and transient.^[7] Hematologic toxicities are frequent, with decreased neutrophil counts (neutropenia) occurring in 50% of patients with relapsed or refractory large B-cell lymphoma (LBCL), including grade 3 or 4 events in 32%; anemia (decreased hemoglobin) in 62% overall (12% grade 3 or 4); and thrombocytopenia (decreased platelets) in 48% overall (12% grade 3 or 4).^[7] Fatigue, a common general symptom potentially linked to these cytopenias, was reported in 29% of LBCL patients, with grade 3 or 4 severity in 2.5%.^[7] Gastrointestinal effects include abdominal pain in 23% of patients (1.9% grade 3 or 4), diarrhea in 20%, and nausea in 20% (1.3% grade 3 or 4), along with vomiting in 12%.^[7] Injection-site reactions, often considered in this category due to local administration, affect 27% of patients and are typically grade 1 or 2.^[7] Musculoskeletal and general disorders encompass pain in 28% of patients (1.3% grade 3 or 4) and edema in 14% (1.9% grade 3 or 4); these are often self-limiting and resolve without intervention.^[7] Laboratory abnormalities beyond hematologic changes include decreased lymphocyte counts in 87% of LBCL patients (77% grade 3 or 4) and decreased white blood cell counts in 53% (22% grade 3 or 4).^[7] Elevated liver enzymes, such as increased alanine aminotransferase and aspartate aminotransferase, occur commonly (around 15% overall), with grade 3 or 4 events in a subset of cases.^[28] Tumor lysis syndrome is a noted risk, particularly in patients with high tumor burden, though it occurred in only 0.6% in trials.^[7] Premedication with corticosteroids and antihistamines, as part of the dosing regimen, helps mitigate some of these effects.^[7] Overall, epcoritamab demonstrates good tolerability, with serious adverse reactions in 54% of LBCL patients and treatment discontinuation due to adverse events in approximately 3.8%.^[7]

Pharmacology

Pharmacodynamics

Epcoritamab, a bispecific CD3xCD20 antibody, achieves near-complete saturation of CD20 receptors on B cells at therapeutic doses, such as the recommended 48 mg full dose, due to its high binding affinity (K_D ≈ 2.5–10 nM for CD20 on human B cells).^[16] CD3 engagement on T cells occurs selectively in the presence of CD20-positive cells, forming immune synapses that minimize off-target T-cell activation.^[11] In vitro potency assessments demonstrate effective T-cell redirection, with EC50 values for T-cell-mediated lysis of CD20+ cell lines ranging from 0.3 to 4 pM across various effector-to-target ratios.^[17] Treatment with epcoritamab leads to rapid depletion of circulating B cells, reducing CD19+ counts to undetectable levels (<10 cells/μL) within days after the first full dose, with depletion sustained for months during continued therapy in patients with baseline detectable B cells.^[11] This kinetic profile reflects efficient T-cell-directed cytotoxicity against CD20-expressing targets, maintaining low B-cell levels even after dose interruptions.^[28] Cytokine release following epcoritamab administration is dose-dependent and primarily involves T-cell activation markers, with peak levels of IL-6 and IFN-γ observed 1–4 days post-initial full dose, correlating closely with the onset of cytokine release syndrome.^[11] Other cytokines, including IL-2, IL-10, and TNF-α, show transient elevations that resolve to baseline prior to subsequent doses, supporting the step-up dosing strategy to mitigate excessive immune activation.^[28] Potential resistance to epcoritamab may arise in tumors with low CD20 expression, where reduced antigen density limits T-cell engagement and cytotoxicity.^[28] Fc-insensitive tumor microenvironments could further impair efficacy by altering effector functions, though clinical data remain limited.^[17]

Pharmacokinetics

Epcoritamab, administered subcutaneously, exhibits slow absorption with median time to maximum plasma concentration (T_max) of approximately 4 days (range: 0.3–7 days) following the first full 48 mg dose in patients with relapsed or refractory large B-cell lymphoma. By the end of weekly dosing in Cycle 3, T_max shortens to about 2.3 days (range: 0.3–3.2 days).^[7] The geometric mean central volume of distribution for epcoritamab is 8.27 L (27.5% coefficient of variation), while the apparent steady-state volume of distribution is 25.6 L (81.8% CV), suggesting distribution into extravascular spaces beyond plasma. Physiologically based pharmacokinetic modeling indicates effective penetration into lymphoid tissues, including lymph nodes and tumor sites, consistent with its mechanism targeting CD20-expressing B cells.^[28]^[30] As a monoclonal antibody, epcoritamab is expected to undergo catabolism via proteolytic degradation into small peptides and amino acids through general pathways for immunoglobulin G1 molecules, without involvement of cytochrome P450 enzymes.^[7] Elimination of epcoritamab follows nonlinear pharmacokinetics due to saturable target-mediated drug disposition, particularly at lower doses. The terminal half-life is concentration-dependent, approximately 22–25 days (58% CV) for the 48 mg dose at the end of Cycle 3. Apparent total clearance is about 0.53 L/day (40% CV) after Cycle 3, decreasing with repeated dosing as steady state is approached. Step-up dosing in the initial cycles leads to progressively higher exposure, with average concentrations (C_avg) increasing from 1.3 mcg/mL after the first 48 mg dose to 9.1 mcg/mL by Cycle 3.^[7]^[28]^[31] No clinically significant differences in pharmacokinetics are observed based on age (20–89 years), sex, race (White or Asian), mild to moderate renal impairment (creatinine clearance 30–<90 mL/min), or mild hepatic impairment. Dose adjustments are not required for these factors; however, pharmacokinetics in severe renal impairment, end-stage renal disease, or moderate to severe hepatic impairment have not been studied. Body weight influences exposure, with approximately 31% lower levels in patients weighing 85–172 kg compared to 65–<85 kg, though this is not considered clinically relevant for dosing.^[7]^[28]

Clinical development

Pivotal trials

The pivotal trials for epcoritamab, a bispecific T-cell engaging antibody targeting CD3 and CD20, primarily include phase 1/2 studies that supported its accelerated approvals for relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL). These trials focused on heavily pretreated patients and demonstrated meaningful response rates, leading to regulatory authorizations based on overall response rate (ORR) as the primary endpoint, with ongoing phase 3 studies to confirm clinical benefit through progression-free survival (PFS) and overall survival (OS) endpoints. The EPCORE NHL-1 trial (NCT03625037) is a phase 1/2, single-arm, multicenter study evaluating epcoritamab monotherapy in R/R B-cell non-Hodgkin lymphoma, including dedicated cohorts for DLBCL and FL. In the DLBCL cohort, 157 patients with R/R large B-cell lymphoma (including 139 with DLBCL) who had received at least two prior lines of therapy were enrolled; the primary endpoint was ORR assessed by positron emission tomography-computed tomography (PET-CT) per independent review committee. As of the April 2023 data cutoff with a median follow-up of 25.1 months, the trial met its endpoint with an ORR of 63.1% (99/157 patients; 95% CI, 55.0-70.6) and a complete response (CR) rate of 40.1% (63/157 patients; 95% CI, 32.4-48.2). The median duration of response (DOR) was 17.3 months (95% CI, 9.7-26.5), establishing durable responses in this high-risk population, with 3-year follow-up data in 2025 confirming a 36-month median duration of CR.^[32]^[33]^[34] Subgroup analyses showed consistent efficacy across patients with prior CAR T-cell therapy (CR rate 36%) and those naïve to CAR T (CR rate 43%), though responses were numerically higher in the non-germinal center B-cell (non-GCB) subtype compared to germinal center B-cell (GCB) subtype in earlier data cutoffs. In the FL cohort of EPCORE NHL-1, 128 patients with R/R FL after at least two prior systemic therapies (including an anti-CD20 antibody) were treated, with the primary endpoint again being ORR by independent review. At a median follow-up of 17.4 months, epcoritamab achieved an ORR of 82.0% (105/128 patients; 95% CI, 74.1-88.2) and a CR rate of 62.5% (80/128 patients), with responses observed across third-line and later settings. The median DOR was not reached in responders, supporting the drug's activity in multiply relapsed FL. These results from the pivotal cohort underpinned the accelerated approval for R/R FL after two or more prior lines of therapy.^[35]^[4] The EPCORE NHL-6 trial (NCT05451810), a phase 2, open-label study, assessed the feasibility of outpatient administration of subcutaneous epcoritamab monotherapy in 92 patients with R/R DLBCL after one or more prior lines of therapy, with primary endpoints focused on safety and the proportion of cycles administered outpatient. Of the 88 patients receiving the full 48 mg dose, 92% (81/88) were successfully monitored outpatient for the first full dose, and 97% of all cycles across the study were completed in the outpatient setting, demonstrating high feasibility with a safety profile comparable to inpatient administration from prior trials. Efficacy was similar to historical data, with an ORR of 64.3% and CR rate of 47.6% in patients with one prior therapy (median follow-up 5.8 months), and no new safety signals emerged. Updated results as of September 2025 confirmed these findings.^[23]^[36] Approvals for epcoritamab in R/R DLBCL and FL were granted on an accelerated basis relying on ORR and CR rates from these single-arm pivotal trials, with requirements for confirmatory evidence from phase 3 studies such as EPCORE DLBCL-1 (NCT04628494), an ongoing randomized trial comparing epcoritamab monotherapy to investigator's choice chemotherapy in R/R DLBCL after at least one prior line of systemic therapy, with co-primary endpoints of ORR and PFS. Limitations of the pivotal data include the lack of randomized controls and reliance on surrogate endpoints, highlighting the need for mature OS and PFS results to verify long-term benefit.^[37]

Ongoing studies

Epcoritamab is being evaluated in multiple phase 3 trials to expand its role in treating B-cell malignancies. The EPCORE DLBCL-1 trial (NCT04628494) is a randomized, open-label phase 3 study comparing epcoritamab monotherapy to standard investigator's choice therapy in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after at least one prior line of systemic therapy, enrolling over 900 participants to assess progression-free survival as the primary endpoint.^[37] The EPCORE FL-1 trial (NCT05409066) investigates epcoritamab in combination with rituximab and lenalidomide in relapsed or refractory follicular lymphoma (FL) after at least one prior line of therapy, with enrollment completed and dual primary endpoints of progression-free survival and overall response rate met in August 2025.^[13]^[10] Combination therapy approaches are a key focus of ongoing research, building on pivotal trial foundations to improve outcomes in earlier treatment lines. The EPCORE NHL-5 trial (NCT05283720), a phase 1b/2 study, evaluates epcoritamab with rituximab and lenalidomide in relapsed or refractory FL and DLBCL, reporting an overall response rate of 75% in an FL cohort of 24 patients. Additional trials explore epcoritamab with polatuzumab vedotin in combination regimens such as pola-R-CHP for first-line DLBCL, demonstrating durable efficacy with expanded CD8-positive T-cell activation in interim data presented in 2025.^[38] Partnerships are also assessing epcoritamab plus azacitidine in non-Hodgkin lymphoma settings, particularly for patients ineligible for intensive therapies, in an open-label phase 1b/2 study evaluating safety and tolerability.^[39] Efforts to broaden indications include phase 2 investigations in less common subtypes. Epcoritamab monotherapy is under evaluation in relapsed or refractory mantle cell lymphoma as part of the basket EPCORE NHL-1 trial (NCT03625037), which encompasses various B-cell non-Hodgkin lymphomas and reports preliminary antitumor activity.^[40] For marginal zone lymphoma, a dedicated phase 2 trial (NCT06796998) assesses epcoritamab's efficacy in newly diagnosed or relapsed patients, focusing on response durability.^[41] In Richter's transformation, phase 2 data from compassionate use and trial cohorts indicate overall response rates of up to 50% with 35% complete responses, with 2-year follow-up in 2025 showing promising efficacy and sustained responses.^[42]^[43] Pediatric studies, such as the phase 1b EPCORE Peds-1 trial (NCT05206357) initiated in 2022, continue to enroll children and young adults with relapsed or refractory aggressive mature B-cell neoplasms to determine safety and dosing as of 2025.^[44] Biomarker research accompanies these efforts to identify predictors of response. Ongoing studies examine CD20 expression levels on tumor cells as a potential correlate to epcoritamab efficacy, with higher expression linked to improved T-cell redirection in preclinical and early clinical analyses.^[45] Parallel investigations into T-cell fitness, including CD8+ cytotoxic T-cell expansion and regulatory CD4+ T-cell dynamics, show associations with complete remission rates, guiding patient selection in trials like EPCORE NHL-1.^[46]^[45]

History and regulation

Development timeline

Epcoritamab, known during development as GEN3013 or DuoBody-CD3xCD20, was discovered and developed by Genmab using its proprietary DuoBody technology, which facilitates the creation of bispecific antibodies with favorable pharmacokinetic properties suitable for subcutaneous administration.^[18] Preclinical studies demonstrated that epcoritamab exhibited superior potency in T-cell-mediated killing of malignant B cells compared to other CD3xCD20 bispecific antibodies in clinical development, as well as bispecifics targeting alternative B-cell antigens, in in vitro models of B-cell non-Hodgkin lymphoma.^[18] These studies, published in 2020, highlighted epcoritamab's strong activation of T cells and selective cytotoxicity against CD20-positive tumor cells, supporting its advancement to clinical testing.^[47] The first-in-human phase 1/2 trial (NCT03625037) initiated in June 2018 to evaluate the safety, tolerability, and preliminary efficacy of subcutaneous epcoritamab in patients with relapsed or refractory B-cell non-Hodgkin lymphoma.^[40] Early dose-escalation data from this trial informed the recommended phase 2 dose of 48 mg, incorporating step-up dosing strategies to mitigate cytokine release syndrome (CRS). Key milestones included the presentation of positive phase 1/2 data at the 2020 American Society of Hematology (ASH) Annual Meeting, which showed encouraging complete response rates and a manageable safety profile in heavily pretreated patients, including those with diffuse large B-cell lymphoma.^[48] In June 2020, Genmab announced a broad oncology collaboration with AbbVie to co-develop and commercialize epcoritamab, along with other bispecific programs, providing shared resources for further clinical advancement.^[49] Pre-approval development addressed challenges such as optimizing dosing to reduce CRS incidence and severity, with step-up regimens (e.g., priming and intermediate doses) established during phase 1/2 dose escalation to enable safer outpatient administration. Subcutaneous formulation optimization, leveraging DuoBody technology for prolonged half-life and reduced injection volume, was completed by 2021, confirming feasibility for clinical use without intravenous requirements.^[47] Genmab and AbbVie submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration in mid-2022 for epcoritamab in relapsed or refractory large B-cell lymphoma, supported by data from the phase 1/2 EPCORE NHL-1 trial.^[50] The FDA accepted the BLA for priority review in November 2022.^[51]

Regulatory approvals

Epcoritamab received accelerated approval from the U.S. Food and Drug Administration (FDA) on May 19, 2023, for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL), including DLBCL arising from low-grade lymphoma, primary mediastinal large B-cell lymphoma, high-grade B-cell lymphoma, or follicular lymphoma grade 3B, who have received at least two prior lines of systemic therapy. This approval was based on overall response rate (ORR) and complete response (CR) data from the single-arm phase 1/2 EPCORE NHL-1 trial, which demonstrated an ORR of 61% (95% CI: 52.5-68.7) and CR rate of 38% (95% CI: 30.0-46.2) in 148 efficacy-evaluable patients. As an accelerated approval, it requires confirmatory evidence from the ongoing phase 3 EPCORE DLBCL-1 trial to verify clinical benefit, particularly overall survival (OS), with no conversion to full approval as of November 2025. On June 26, 2024, the FDA expanded accelerated approval to include adult patients with R/R follicular lymphoma (FL) who have received at least two prior lines of systemic therapy.^[4] This was supported by EPCORE NHL-1 data in 127 efficacy-evaluable patients, showing an ORR of 82% (95% CI: 74.1-88.2) and CR rate of 60% (95% CI: 50.8-68.4).^[4] Confirmatory data for OS are anticipated from the phase 3 EPCORE FL-1 trial, with a PDUFA target action date of November 30, 2025. In August 2025, Genmab and AbbVie announced positive topline results from the phase 3 EPCORE FL-1 trial, demonstrating statistically significant improvement in progression-free survival and overall response rate for epcoritamab plus rituximab and lenalidomide versus rituximab and lenalidomide alone in patients with relapsed or refractory follicular lymphoma after one prior line of therapy. A supplemental Biologics License Application was submitted to the FDA, with a target action date of November 30, 2025.^[10] In the European Union, the European Commission granted conditional marketing authorization for epcoritamab on September 22, 2023, for the treatment of adults with R/R DLBCL after at least two prior systemic therapies.^[5] The approval relied on the same single-arm EPCORE NHL-1 trial results for ORR and CR.^[15] This was extended on August 19, 2024, to include adults with R/R FL after at least two prior systemic therapies.^[52] As a conditional approval, ongoing obligations include submission of phase 3 OS data from confirmatory trials to support full authorization.^[28] Epcoritamab has also been approved in other regions, including Canada with conditional notice of compliance on October 13, 2023, for R/R DLBCL;^[53] Japan on September 25, 2023, for R/R large B-cell lymphomas including DLBCL, and extended on February 20, 2025, to include R/R follicular lymphoma after at least two prior lines of systemic therapy;^[54]^[55] and Australia with provisional approval on July 9, 2025, for R/R DLBCL.^[56] As of November 2025, applications for approval in China remain under review by the National Medical Products Administration for both DLBCL and FL indications. The phase 2 EPCORE NHL-6 trial evaluated subcutaneous epcoritamab monotherapy in R/R DLBCL patients under outpatient conditions and reported an ORR of 64.3% with a CR rate of 47.6% (n=42; median follow-up 5.8 months).^[23]

Society and culture

Legal status

Epcoritamab has received orphan drug designation from the U.S. Food and Drug Administration (FDA) for the treatment of relapsed or refractory follicular lymphoma (FL).^[57] Similarly, the European Medicines Agency (EMA) granted orphan designation for epcoritamab in DLBCL in February 2022 and in FL in June 2022.^[58]^[59] These designations provide incentives such as market exclusivity and tax credits to support development for rare diseases affecting fewer than 200,000 patients annually in the U.S. or with similar prevalence criteria in the EU. Additionally, the FDA granted breakthrough therapy designation to epcoritamab for relapsed or refractory FL after two or more prior lines of systemic therapy, based on preliminary evidence of substantial improvement over available therapies.^[60]^[61] In the United States, epcoritamab is covered as an outpatient drug under Medicare Part B, which includes injectable biologics administered by healthcare providers.^[62]^[63] This coverage applies to eligible patients with approved indications, subject to standard deductibles and coinsurance. In the United Kingdom, the National Institute for Health and Care Excellence (NICE) recommended epcoritamab for routine NHS use in March 2024 for adults with relapsed or refractory DLBCL after two or more prior systemic treatments, supported by a commercial patient access scheme to address cost-effectiveness concerns.^[64]^[65] The FDA prescribing information includes a boxed warning for cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), highlighting the risks of serious or life-threatening reactions, including neurologic toxicity.^[11]^[66] By November 2025, epcoritamab has received regulatory approval in more than 30 countries, including the United States, European Union member states, the United Kingdom, Japan, Canada, and select Latin American nations such as Argentina, Brazil, and Mexico.^[67]^[68]^[69] However, access remains limited in low- and middle-income regions due to its high cost, estimated at approximately $300,000 for a full treatment course based on monthly pricing of $37,500 and typical durations of 8 to 12 months.^[70]^[71] This pricing contributes to global disparities, with availability concentrated in high-income settings where reimbursement supports uptake. Epcoritamab benefits from U.S. orphan drug exclusivity for the FL indication until June 26, 2031, providing seven years of market protection from the date of FDA approval for FL on June 26, 2024.^[57]^[4] Pediatric investigations are ongoing, including a phase 1/2 trial in relapsed or refractory aggressive mature B-cell lymphomas (NCT05206357), which could qualify for a six-month exclusivity extension upon completion and FDA review.^[44] Patent protection, including for the bispecific antibody construct, extends through at least 2039 in some jurisdictions, though U.S.-specific expiration details incorporate regulatory review periods for potential further extension.^[72]^[73]

Brand names and availability

Epcoritamab is marketed under the brand name Epkinly in the United States, Canada, Australia, and Japan.^[74]^[75]^[76]^[77] In the European Union and the United Kingdom, it is sold as Tepkinly.^[5]^[78] The drug was developed by the Danish biotechnology company Genmab and is co-developed and co-promoted by AbbVie under a collaboration agreement established in 2020.^[49] Epcoritamab is produced using recombinant DNA technology in Chinese hamster ovary (CHO) cells.^[11]^[28] Epcoritamab became commercially available in the United States in 2023 following accelerated FDA approval in May of that year, and in the European Union later in 2023 after conditional marketing authorization from the EMA in September.^[79]^[5] It is supplied as a solution for subcutaneous injection in single-dose vials (4 mg/0.8 mL and 48 mg/0.8 mL), with lower doses requiring dilution prior to administration.^[11]^[28] The product must be stored refrigerated at 2°C to 8°C (36°F to 46°F) in its original carton to protect from light and should not be frozen or shaken.^[11]^[28] In the United States, the wholesale acquisition cost for the standard 48 mg vial is $16,480.30 as of July 2025, while the 4 mg vial costs $1,373.36.^[80] AbbVie offers patient access support through the MyNavCare program, which provides co-pay assistance for eligible commercially insured patients (potentially reducing out-of-pocket costs to $0 per dose, up to $25,000 annually) and free medication for qualifying uninsured or underinsured individuals.^[81]^[82] Manufacturing occurs at global facilities, including sites in the United States (Rentschler Biopharma) and Europe, with Genmab overseeing development from its headquarters in Denmark.^[28]^[49] No supply shortages have been reported as of November 2025.
