Press Release: ASCO: new Sarclisa data support subcutaneous administration with on-body injector

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]
