Core Insights - New data from clinical studies support the subcutaneous administration of Sarclisa via an on-body injector, demonstrating non-inferior efficacy and safety compared to intravenous infusion [1][5][6] Group 1: Clinical Study Findings - The IRAKLIA phase 3 study showed very good partial response (VGPR) rates of 46.4% for Sarclisa SC-Pd and 45.9% for Sarclisa IV-Pd, indicating non-inferiority [5] - The objective response rate (ORR) for Sarclisa SC-Pd was 71.1% compared to 70.5% for Sarclisa IV-Pd, establishing non-inferiority [7] - The overall safety profile of Sarclisa SC-Pd was consistent with Sarclisa IV-Pd, with a lower rate of systemic infusion reactions (1.5% vs. 25%) [12][8] Group 2: Patient Experience and Administration - The on-body injector (OBI) is expected to enhance patient experience by providing greater convenience and flexibility, leading to higher patient satisfaction scores [2][9] - 70% of patients treated with Sarclisa SC-Pd reported satisfaction with their injection, compared to 53.4% in the IV-Pd group [12] - The OBI allows for a hands-free administration process, potentially reducing the physical burden on healthcare providers [2][11] Group 3: Future Directions and Regulatory Submissions - Data from the IRAKLIA and IZALCO studies will form the basis for global regulatory submissions for Sarclisa SC administration [6][14] - Sanofi is also exploring Sarclisa SC administration in front-line treatment settings through additional studies [14] - The IRAKLIA study's abstract was selected for the 2025 Best of ASCO program, highlighting its significance in the field [14]

Core Insights - New clinical studies demonstrate the efficacy and safety of Sarclisa administered subcutaneously via an on-body injector (OBI) for relapsed or refractory multiple myeloma (R/R MM) [1][7][10] - The studies presented at the ASCO Annual Meeting show that the OBI method offers non-inferior efficacy compared to traditional intravenous (IV) administration [1][5][10] Study Details - The IRAKLIA phase 3 study is a pivotal non-inferiority trial comparing Sarclisa SC via OBI with Sarclisa IV, both combined with pomalidomide and dexamethasone in adult patients with R/R MM [5][17] - The study reported an overall response rate (ORR) of 71.1% for Sarclisa SC-Pd versus 70.5% for Sarclisa IV-Pd, establishing non-inferiority [8] - The safety profile of Sarclisa SC-Pd was consistent with Sarclisa IV-Pd, with a lower incidence of systemic infusion reactions (1.5% vs. 25%) [9][13] Patient Experience - The OBI is designed to enhance patient comfort and satisfaction, with 70% of patients preferring the OBI over manual injection [13][14] - Patient satisfaction scores were significantly higher for the OBI method, with 74.5% of patients expressing a preference for it [14][15] Future Directions - Sanofi is exploring further applications of Sarclisa SC via OBI in various treatment settings, including front-line therapy for newly diagnosed multiple myeloma patients [15][20] - Data from the IRAKLIA and IZALCO studies will support global regulatory submissions for the OBI delivery method [7][15]
