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].

Lunsumio provides high and long-lasting response rates, with approximately two-thirds of patients with a complete response in remission after four years1Subcutaneous Lunsumio has potential to substantially reduce treatment administration time with an approximately one minute injection, compared with 2-4 hours IV infusionIf approved, Lunsumio would be the first treatment available for people with follicular lymphoma after two or more lines of systemic therapy, which is both fixed-duration and subcutaneously ...
