Roche presents new data demonstrating the potential benefit of glofitamab and Lunsumio as fixed-duration, off-the-shelf treatment options for lymphoma
Roche (RHHBY) presented updated clinical data on its bispecific antibodies, glofitamab and Lunsumio, at the ASH 2022 meeting. Glofitamab showed promising results in heavily pre-treated large B-cell lymphoma, with 61% of patients maintaining complete responses (CR) after 12 months. Lunsumio also exhibited high efficacy in relapsed follicular lymphoma, achieving a 60% CR rate. Both treatments are designed to offer fixed-duration therapies, enhancing patient outcomes and treatment convenience. Regulatory submissions for glofitamab are ongoing in Europe and the U.S.

Basel, 12 December 2022 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that updated clinical data for its CD20xCD3 T-cell engaging bispecific antibodies, including five oral presentations, were presented at the 64th American Society of Hematology (ASH) Annual Meeting & Exposition, 10-13 December 2022. Updated results for investigational bispecific glofitamab in people with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) suggest glofitamab has the potential to be the first, off-the-shelf CD20xCD3 T-cell engaging bispecific antibody that can be given for a fixed period of time to people with heavily pre-treated aggressive lymphoma.1 These data will be presented at the meeting, and simultaneously published online in the New England Journal of Medicine (NEJM).2 Additionally, updated data for Lunsumio® (mosunetuzumab) continued to demonstrate clinically meaningful outcomes in people with heavily pre-treated follicular lymphoma (FL).3 Lunsumio is a fixed-duration treatment that can be administered in the outpatient setting, which could allow people the possibility of experiencing a lasting remission with a treatment-free period.3
“We pioneered the development of T-cell engaging bispecific antibodies for lymphoma with the aim of expanding treatment options for people with difficult-to-treat blood cancers,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “New glofitamab and Lunsumio data continue to demonstrate durable and impressive patient responses, including complete remissions, when given for a fixed period of time. We believe these medicines could potentially transform treatment and offer new hope for people with lymphomas.”
Pivotal phase II glofitamab data presented at ASH 2022 and published in NEJM
Updated data from the pivotal phase II NP30179 study in people with R/R LBCL showed glofitamab given as a fixed course induced early and durable responses that were maintained beyond the end of treatment. Most patients who had achieved a complete response (CR; a disappearance of all signs of cancer) at the end of treatment experienced durable responses, with a median CR follow-up from end of treatment of 11.5 months (
Simultaneously, an earlier data cut from the phase II NP30179 study in R/R diffuse large B-cell lymphoma (DLBCL) was published online in NEJM.2
Data from this pivotal phase II study have been submitted for review to the European Medicines Agency, and submissions to additional health authorities worldwide, including the U.S. Food and Drug Administration (FDA), are ongoing.
Updated pivotal phase II Lunsumio data presented at ASH 2022
An updated analysis from the pivotal phase II GO29781 study of Lunsumio in people with R/R FL who had received two or more prior therapies showed
The European Commission granted conditional marketing authorisation for Lunsumio for the treatment of people with R/R FL who have received at least two prior systemic therapies in June 2022, making it the first and only fixed-duration bispecific antibody to be approved in Europe for lymphoma. Lunsumio is under Priority Review with the FDA, with a decision expected by 29 December 2022.
Additional Lunsumio and glofitamab data presented at ASH 2022
Roche continues to evaluate Lunsumio and glofitamab as part of its commitment to providing off-the-shelf therapies for people with lymphomas that can meet their diverse needs, including fixed-duration treatment options. Additional data presented at ASH 2022 include the following:
- A subcutaneous (SC) formulation of Lunsumio (administered as an injection given under the skin) demonstrated comparable efficacy with the intravenous formulation and a manageable safety profile in people with R/R non-Hodgkin lymphoma (NHL). The most common AEs were injection site reactions (
60.9% ; n=53/87) and CRS events (27.6% ; n=24/87), which were all Grade 1 or 2. These findings suggest that a SC formulation of Lunsumio may offer patients a treatment option that could reduce their time spent in treatment centres.4 - Updated results from the phase I/II G050554 study of Lunsumio monotherapy in elderly/unfit patients with previously untreated DLBCL and additional analyses from the phase I/II G040516 study of Lunsumio in combination with Polivy® (polatuzumab vedotin) in heavily pre-treated people with DLBCL continued to show promising efficacy and manageable safety, highlighting the potential of Lunsumio in these patient populations.5,6
- Results from the phase I/II NP30179 study evaluating glofitamab as a monotherapy following pre-treatment with Gazyva®/Gazyvaro® (obinutuzumab) in patients with heavily pre-treated R/R mantle cell lymphoma continued to show early, high and durable response rates in this difficult-to-treat disease. After a median follow-up of eight months, the overall response rate (ORR) was
83.8% , with the majority of patients showing durable complete responses at the data cut off (74.1% ; n=20/27). The most common AE was CRS (75.5% ; n=28/37), with the majority low grade.7 - Data from the safety and expansion cohorts of the phase Ib NP40126 study evaluating glofitamab in combination with MabThera®/Rituxan® (rituximab) plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) in patients with previously untreated DLBCL showed, after a median follow-up of 8.5 months, a best ORR of
92.7% (n=51/55) and a complete metabolic response rate of72.7% (n=40/55). In the safety cohort, CRS events were all low grade (Grade 1 or 2 [10.7% ; n=6/56]), and serious AEs were reported in 18 patients (32.1% ).8
Both Lunsumio and glofitamab are being investigated as SC formulations and in phase III studies that will expand the understanding of their impact in earlier lines of treatment, with the aim of continuing to address the diverse needs and preferences of people with blood cancers. This includes the confirmatory phase III CELESTIMO study investigating Lunsumio plus lenalidomide as a chemotherapy-free option for patients with R/R FL; the phase III SUNMO study investigating Lunsumio plus Polivy versus MabThera/Rituxan in combination with gemcitabine plus oxaliplatin (R-GemOx) in patients with R/R aggressive B-cell NHL who are ineligible for autologous stem cell transplant (ASCT); and the phase III STARGLO study evaluating glofitamab in combination with gemcitabine and oxaliplatin (GemOx) versus MabThera/Rituxan in combination with GemOx in patients with R/R DLBCL who are ineligible for ASCT.
About glofitamab
Glofitamab is an investigational CD20xCD3 T-cell-engaging bispecific antibody designed to target CD3 on the surface of T-cells and CD20 on the surface of B-cells. Glofitamab was designed with a novel 2:1 structural format. This T-cell-engaging bispecific antibody is engineered to have one region that binds to CD3, a protein on T-cells, a type of immune cell, and two regions that bind to CD20, a protein on B-cells, which can be healthy or malignant. This dual-targeting brings the T-cell in close proximity to the B-cell, activating the release of cancer cell-killing proteins from the T-cell. A robust clinical development program for glofitamab is ongoing, investigating the molecule as a monotherapy and in combination with other medicines for the treatment of people with B-cell non-Hodgkin’s lymphomas, including diffuse large B-cell lymphoma and other blood cancers.
About Lunsumio® (mosunetuzumab)
Lunsumio is a 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, and other blood cancers.
