Lunsumio provides high rates of deep and long-lasting responses in third-line and later follicular lymphoma, a disease that typically becomes harder to treat each time a patient relapses1,2 Lunsumio subcutaneous offers a new treatment option that can significantly reduce administration time to approximately one minute Availability of Lunsumio SC allows patients to receive treatment aligned to clinical requirements and lifestyle preferences 19 November 2025 - Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that the European Commission has granted conditional marketing authorisation of Lunsumio® (mosunetuzumab) subcutaneous (SC) for the treatment of adult patients with relapsed or refractory (R/R) follicular lymphoma (FL) after two or more lines of systemic therapy. Approval is based on results from the phase I/II GO29781 study, which showed that Lunsumio SC had pharmacokinetic non-inferiority compared with intravenous (IV) administration, with no unexpected safety signals.3 “Building on the benefits of its fixed-duration dosing schedule, Lunsumio can now be administered with a one-minute subcutaneous injection, providing people with relapsed or refractory follicular lymphoma an additional treatment option to help meet their individual clinical requirements and lifestyle preferences,” said Levi Garraway, MD, PhD, Roche’s Chief Medical Officer and Head of Global Product Development. “Developing new formulations of our medicines is part of our commitment to offering greater flexibility and a better treatment experience for patients.” Lunsumio SC is a fixed-duration treatment that can be initiated in the outpatient setting and has the potential to substantially reduce treatment administration time with an approximately one-minute injection, compared with a 2-4 hour IV infusion. Lunsumio has shown a favourable benefit-risk profile and high rates of deep and durable remissions with both IV and SC administration routes in third-line or later (3L+) FL.1,4 Lunsumio IV was the first bispecific antibody approved for 3L+ FL and has shown sustained responses, with 57% of patients who achieved a CR still in remission at five years.1 Long-term data from the SC and IV arms of the GO29781 study will be presented at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition. These data have been submitted to other healthcare authorities around the world, including the US Food and Drug Administration. Phase III studies involving Lunsumio SC are ongoing, including the MorningLyte trial investigating Lunsumio SC in combination with lenalidomide in previously untreated FL. Lunsumio, along with Columvi® (glofitamab), is part of Roche’s industry-leading CD20xCD3 bispecific antibody portfolio. Continuing to explore new formulations and combinations of these medicines across different disease areas and lines of treatment is part of Roche’s commitment to improve the patient experience and provide more choice to suit diverse patient and healthcare system needs. The GO29781 study is a phase II, multicentre, open-label, dose-escalation and expansion study evaluating the safety, efficacy and pharmacokinetics of Lunsumio® (mosunetuzumab), administered both as an intravenous (IV) and subcutaneous (SC) treatment, in people with relapsed or refractory B-cell non-Hodgkin lymphoma. The primary objective for the SC cohort was to show pharmacokinetic (PK) non-inferiority of the SC formulation of Lunsumio compared with the IV formulation, based on the study’s co-primary endpoints. Key secondary endpoints include complete response (CR) rate, objective response rate (ORR), duration of response, progression-free survival, safety and tolerability. This approval is based on a primary analysis that explored Lunsumio administered subcutaneously in patients with 3L+ follicular lymphoma. Results from the primary analysis showed PK non-inferiority compared with IV administration, and the ORR and CR rates in patients treated with the fixed-duration, subcutaneous formulation of Lunsumio were 74.5% (95% confidence interval [CI]: 64.4-82.9%) and 58.5% (95% CI: 46.9-68.6%), respectively, as evaluated by the independent review faculty. The median duration of CR was 20.8 months (95% CI: 18.8-not evaluable [NE]) for patients receiving Lunsumio SC. The most common all-grade adverse events were injection-site reactions (60.6%; all Grade 1-2), fatigue (35.1%), and cytokine release syndrome (CRS; 29.8%). Overall, the rate and severity of CRS were low; events were low grade (Grade 1-2, 27.7%; Grade 3, 2.1%), occurred during cycle 1 and all fully resolved in a median of two days (range 1-15 days).3 Follicular lymphoma (FL) is the most common slow-growing (indolent) form of non-Hodgkin lymphoma, accounting for about one in five cases.2,5 It typically responds well to treatment but is often characterised by periods of remission and relapse.2 The disease typically becomes harder to treat each time a patient relapses, and early progression can be associated with poor long-term prognosis.5 It is estimated that more than 110,000 people are diagnosed with FL each year worldwide.5,6 Lunsumio is a first-in-class CD20xCD3 T-cell engaging bispecific antibody designed to target CD20 on the surface of B cells and CD3 on the surface of T cells. This dual targeting activates and redirects a patient’s existing T cells to engage and eliminate target B cells by releasing cytotoxic proteins into the B cells. A robust clinical development programme for Lunsumio is ongoing, investigating the molecule as a monotherapy and in combination with other medicines, for the treatment of people with B-cell non-Hodgkin lymphomas, including follicular lymphoma and diffuse large B-cell lymphoma, other blood cancers and autoimmune disorders.

COPENHAGEN, Denmark--(BUSINESS WIRE)--Genmab A/S (Nasdaq: GMAB) announced today that EPKINLY® (epcoritamab-bysp) in combination with rituximab and lenalidomide (EPKINLY + R2) was approved by the U.S. Food and Drug Administration (FDA) for adult patients with relapsed or refractory (R/R) follicular lymphoma (FL). The approval is based on results from the pivotal Phase 3 EPCORE® FL-1 study that evaluated fixed duration EPKINLY + R2 compared to standard of care R2.i In the study, treatment with fixed duration EPKINLY + R2 reduced the risk of disease progression or death by 79% (HR 0.21, 95% CI: 0.13-0.33, p<0.0001) compared to R2. Median progression-free survival (PFS) was not reached (NR) among patients treated with EPKINLY + R2 (95% CI: 21.9-NR) compared to 11.2 months for patients treated with R2 (95% CI: 10.5-NR). Among patients who were treated with EPKINLY + R2, 89% responded to treatment (n=216/243, 95% CI: 84-93, p<0.0001) and 74% achieved a complete response (CR) (n=181/243, 95% CI: 69-80). This is compared to a 74% overall response rate (n=181/245, 95% CI: 68-79) and 43% CR rate among patients treated with R2 (n=106/245, 95% CI: 37-50).i The Phase 3 EPCORE FL-1 study included patients with relapsed or recurrent FL following at least one prior line of treatment across a broad range of patient characteristics and disease risk factors. The safety profile of EPKINLY + R2 in the EPCORE FL-1 study was generally consistent with the known safety profiles of the individual regimens (epcoritamab and R2). The most common (≥ 20%) adverse reactions in patients who received EPKINLY + R2 were rash, upper respiratory tract infections, fatigue, injection site reactions, constipation, diarrhea, cytokine release syndrome (CRS), pneumonia, COVID-19, and fever. The most common Grade 3 to 4 laboratory abnormalities (≥ 10%) were decreased neutrophil count, lymphocyte count, and platelets. CRS occurred in 24% of patients at the recommended 3 step-up dosing schedule, and was primarily low grade (19% Grade 1, 5% Grade 2). A single event of immune effector cell-associated neurotoxicity syndrome (ICANS) occurred in one patient, grade 1 (0.8%). The prescribing information has a Boxed Warning for serious or fatal CRS and ICANS. Warnings and precautions include infections, cytopenias, and embryo-fetal toxicity. Please see additional Important Safety Information below.i “Recurrent follicular lymphoma can be an incurable, complex, and persistent disease, creating a clear need for additional treatments that can change its course earlier in the treatment journey,” said Lorenzo Falchi, M.D., Lymphoma Specialist, Department of Medicine, Memorial Sloan Kettering Cancer Center. “The results shown with EPKINLY + R2 in the EPCORE FL-1 study are incredibly meaningful, demonstrating durable responses compared to patients treated with R2 alone. These data, delivered by a regimen that’s chemotherapy-free and can be administered in the outpatient setting, suggest that EPKINLY + R2 could potentially become a new standard of care.” FL is typically a slow-growing form of non-Hodgkin lymphoma (NHL) that impacts approximately 15,000 new patients per year in the U.S..ii,iii The disease is considered incurable with current standard of care therapies.iv Patients with FL often relapse, and in some cases, the disease can transform into a more aggressive form of NHL called diffuse large B-cell lymphoma (DLBCL).v “Today’s milestone marks meaningful progress for people living with follicular lymphoma. With a bispecific-based therapy that can be administered in a variety of medical settings, patients have the possibility of accessing this treatment at sites of care closer to where they live,” said Meghan Gutierrez, Chief Executive Officer, Lymphoma Research Foundation. EPKINLY + R2 was previously granted Breakthrough Therapy Designation (BTD) by the FDA for the treatment of R/R FL. This designation is granted to investigational medicines for serious or life-threatening diseases in cases where preliminary clinical evidence shows that the therapy may provide substantial improvements over available therapies. “The FDA approval of EPKINLY + R2 is an important advancement for patients with follicular lymphoma, enabling treatment at initial recurrence when more effective intervention is needed,” said Judith Klimovsky, M.D., Executive Vice President & Chief Development Officer, Genmab. “This milestone also underscores EPKINLY’s potential as the core therapy for B-cell malignancies, demonstrating benefit in combination and earlier disease, and building on its established role as a single agent option in later lines of treatment.” In June 2024, EPKINLY monotherapy was granted accelerated approval by the FDA for the treatment of R/R FL following two or more lines of systemic therapy. With the results from the confirmatory Phase 3 EPCORE FL-1 study, the FDA has also converted the accelerated approval into a full approval. Data from the Phase 3 EPCORE FL-1 study will be presented at the Annual Meeting and Exposition of the American Society of Hematology in December. 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). EPKINLY® (epcoritamab-bysp) U.S. INDICATIONS AND IMPORTANT SAFETY INFORMATION What is EPKINLY? EPKINLY is a prescription medicine used to treat adults with: certain types of diffuse large B-cell lymphoma (DLBCL) or high-grade B-cell lymphoma that has come back (relapsed) or that did not respond (refractory), after 2 or more treatments. EPKINLY for the treatment of DLBCL is approved based on patient response data. Studies are ongoing to confirm the clinical benefit of EPKINLY. EPKINLY for the treatment of DLBCL is approved based on patient response data. Studies are ongoing to confirm the clinical benefit of EPKINLY. follicular lymphoma (FL) that has come back or that did not respond to previous treatment, together with lenalidomide and rituximab follicular lymphoma (FL) that has come back or that did not respond after receiving 2 or more treatments. It is not known if EPKINLY is safe and effective in children. Important Warnings—EPKINLY can cause serious side effects, including: Cytokine release syndrome (CRS) , which is common during treatment with EPKINLY and can be serious or lead to death. To help reduce your risk of CRS, you will receive EPKINLY on a step-up dosing schedule (when you receive 2 or 3 smaller step-up doses of EPKINLY before your first full dose during your first cycle of treatment), and you may also receive other medicines before and for 3 days after receiving EPKINLY. If your dose of EPKINLY is delayed for any reason, you may need to repeat the step-up dosing schedule. Neurologic problems that can be serious, and can be life-threatening, and lead to death. Neurologic problems may happen days or weeks after you receive EPKINLY. People with DLBCL or high-grade B-cell lymphoma should be hospitalized for 24 hours after receiving their first full dose of EPKINLY on Day 15 of Cycle 1 due to the risk of CRS and neurologic problems. People with follicular lymphoma (FL) may need to be hospitalized after receiving their first full dose of EPKINLY on Day 22 of Cycle 1 due to the risk of CRS. Tell your healthcare provider or get medical help right away if you develop a fever of 100.4°F (38°C) or higher; dizziness or lightheadedness; trouble breathing; chills; fast heartbeat; feeling anxious; headache; confusion; shaking (tremors); problems with balance and movement, such as trouble walking; trouble speaking or writing; confusion and disorientation; drowsiness, tiredness or lack of energy; muscle weakness; seizures; or memory loss. These may be symptoms of CRS or neurologic problems. If you have any symptoms that impair consciousness, do not drive or use heavy machinery or do other dangerous activities until your symptoms go away. EPKINLY can cause other serious side effects, including: Infections that may lead to death. Your healthcare provider will check you for signs and symptoms of infection before and during treatment and treat you as needed if you develop an infection. You should receive medicines from your healthcare provider before you start treatment to help prevent infection. Tell your healthcare provider right away if you develop any symptoms of infection during treatment, including fever of 100.4°F (38°C) or higher, cough, chest pain, tiredness, shortness of breath, painful rash, sore throat, pain during urination, feeling weak or generally unwell, or confusion. Low blood cell counts, which can be serious or severe. Your healthcare provider will check your blood cell counts during treatment. EPKINLY may cause low blood cell counts, including low white blood cells (neutropenia and lymphopenia), which can increase your risk for infection; low red blood cells (anemia), which can cause tiredness and shortness of breath; and low platelets (thrombocytopenia), which can cause bruising or bleeding problems. Your healthcare provider will monitor you for symptoms of CRS, neurologic problems, infections, and low blood cell counts during treatment with EPKINLY. Your healthcare provider may temporarily stop or completely stop treatment with EPKINLY if you develop certain side effects. Before you receive EPKINLY, tell your healthcare provider about all your medical conditions, including if you have an infection, are pregnant or plan to become pregnant, or are breastfeeding or plan to breastfeed. If you receive EPKINLY while pregnant, it may harm your unborn baby. If you are a female who can become pregnant, your healthcare provider should do a pregnancy test before you start treatment with EPKINLY and you should use effective birth control (contraception) during treatment and for 4 months after your last dose of EPKINLY. Tell your healthcare provider if you become pregnant or think that you may be pregnant during treatment with EPKINLY. Do not breastfeed during treatment with EPKINLY and for 4 months after your last dose of EPKINLY. The most common side effects of EPKINLY when used alone in DLBCL or high-grade B-cell lymphoma or FL include CRS, injection site reactions, tiredness, muscle and bone pain, fever, diarrhea, COVID-19, rash, and stomach-area (abdominal) pain. The most common severe abnormal laboratory test results with EPKINLY when used alone include decreased white blood cells, decreased red blood cells, and decreased platelets. The most common side effects of EPKINLY when used together with lenalidomide and rituximab in FL include rash, upper respiratory tract infections, tiredness, injection site reactions, constipation, diarrhea, CRS, pneumonia, COVID-19, and fever. The most common severe abnormal laboratory test results with EPKINLY when used together with lenalidomide and rituximab include decreased white blood cells and decreased platelets.

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.ii,iii FL is considered incurable with current standard of care therapies.iv Patients often relapse, and with each relapse the remission and time to next treatment shorten.vi 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 EPKINLY® (epcoritamab-bysp) EPKINLY® (epcoritamab-bysp) 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.vii Epcoritamab (approved under the brand name EPKINLY in countries including the U.S. and Japan, and as TEPKINLY® in the European Union) has received regulatory approval in certain lymphoma indications in more than 65 countries. Epcoritamab is being co-developed by Genmab and AbbVie as part of the companies' oncology collaboration. The companies will share commercialization responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization. Both companies will pursue additional international regulatory approvals for the 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 additional ongoing Phase 3, open-label, randomized trials including a trial evaluating epcoritamab as a monotherapy in patients with R/R DLBCL compared to investigators choice immunochemotherapy (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 rituximab and lenalidomide (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.
