Core Viewpoint - Roche announced that the European Medicines Agency's Committee for Medicinal Products for Human Use has recommended the approval of a subcutaneous formulation of Lunsumio (mosunetuzumab) for adult patients with relapsed or refractory follicular lymphoma after two or more lines of systemic therapy, with a final decision expected from the European Commission soon [1][2]. Group 1: Product Details - Lunsumio is the first approved CD20xCD3 T-cell engaging bispecific antibody, showing high and durable response rates with a favorable safety profile in third-line or later follicular lymphoma [2][7]. - The subcutaneous formulation of Lunsumio has demonstrated pharmacokinetic non-inferiority compared to intravenous administration, with a low rate of cytokine release syndrome at 29.8% [2][6]. - The overall response rate (ORR) for patients treated with the subcutaneous formulation was 74.5%, and the complete response (CR) rate was 58.5%, with a median duration of CR at 20.8 months [6][7]. Group 2: Treatment Administration - The subcutaneous administration of Lunsumio can significantly reduce treatment administration time to approximately one minute, compared to 2-4 hours for intravenous infusion, while maintaining the same dosing schedule [2][7]. - Lunsumio is designed for a fixed duration of approximately 6-12 months, depending on patient response, allowing for a target end date and potential treatment-free periods [2][7]. Group 3: Clinical Study Information - The recommendation is based on the primary analysis of the phase II GO29781 study, which evaluated the safety, efficacy, and pharmacokinetics of Lunsumio administered both intravenously and subcutaneously [5][6]. - The GO29781 study is a multicenter, open-label, dose-escalation and expansion study focusing on relapsed or refractory B-cell non-Hodgkin lymphoma [5]. Group 4: Market Position and Future Plans - Lunsumio, along with Columvi (glofitamab), is part of Roche's leading CD20xCD3 bispecific antibody portfolio, with ongoing exploration of new formulations and combinations across various disease areas [4][10]. - Roche is committed to improving patient experience and providing diverse treatment options to meet healthcare system needs [4][10].

Core Insights - Roche's phase III SUNMO study demonstrated that the combination of Lunsumio® (mosunetuzumab) and Polivy® (polatuzumab vedotin) significantly improves progression-free survival (PFS) and objective response rate (ORR) in patients with relapsed or refractory large B-cell lymphoma (LBCL) compared to the standard treatment R-GemOx [1][2][3] Study Results - The combination therapy showed a 59% reduction in the risk of disease progression or death (hazard ratio [HR] 0.41, p<0.0001) with a median PFS of 11.5 months, three times longer than R-GemOx's 3.8 months [2][3] - The 12-month PFS rate was 48.5% for the combination therapy compared to 17.8% for R-GemOx [2] - Objective response rates were 70.3% for the combination versus 40.0% for R-GemOx, with complete response rates at 51.4% compared to 24.3% [2] Safety Profile - The safety profile of the combination was consistent with known profiles of the individual drugs, with low incidence of cytokine release syndrome (CRS) and fewer adverse events leading to treatment discontinuation [2][3] - Grade 3-4 adverse events were similar between the two treatment arms (58.5% vs. 57.8%) [2] Clinical Implications - The combination therapy may provide an effective alternative to traditional chemotherapy, suitable for outpatient settings, addressing the urgent need for new treatment options in difficult-to-treat LBCL [2][4] - The National Comprehensive Cancer Network (NCCN) has included Lunsumio and Polivy in its guidelines as a category 2A recommendation for second-line treatment of DLBCL [2] Roche's Commitment - Roche aims to enhance treatment options for patients with lymphomas through its extensive portfolio, including ongoing studies with other bispecific antibodies and combination therapies [5][11] - Lunsumio is already approved in over 60 countries for relapsed or refractory follicular lymphoma, while Polivy has approvals in over 100 countries for various indications [6][9]
