- Sarclisa SC formulation added to Pd for the treatment of R/R MM met the co-primary endpoints in the IRAKLIA phase 3 study, demonstrating non-inferiority compared to Sarclisa IV
- IRAKLIA is the first global phase 3 study to evaluate the SC administration of a cancer treatment via an OBDS
- OBDS is an alternative delivery method designed to improve the patient experience and currently available SC administration.
9 January 2025 — Paris, France — Results from the investigational, randomized, open-label IRAKLIA phase 3 study demonstrated that Sarclisa administered at a fixed dose subcutaneously (SC) via an on-body delivery system (OBDS) in combination with pomalidomide and dexamethasone (Pd) met its co-primary endpoints of non-inferior objective response rate (ORR) and observed concentration before dosing (C trough) at steady state compared to intravenous (IV) Sarclisa administered at a weight-based dose in combination with Pd in patients with relapsed or refractory multiple myeloma (R/R MM). Key secondary endpoints, including very good partial response (VGPR), incidence rate of infusion reactions and C trough at cycle 2 were also achieved. The study is ongoing, and the full results will be presented at a forthcoming medical meeting.
Sikander Ailawadhi, MD, Professor of Medicine, Division of Hematology/Oncology at Mayo Clinic Florida and principal investigator of the study: “The consistent overall response rate and comparable efficacy and safety profile observed in the IRAKLIA study for subcutaneous Sarclisa represent an exciting advancement, offering insight into a potential new administration option for patients. The results from IRAKLIA, in patients with relapsed or refractory multiple myeloma, support the potential of an on-body delivery system to help ease the delivery of a new formulation without impacting patient outcomes.”
The IRAKLIA study was conducted using Enable Injections’ enFuse® hands-free OBDS, which was designed to administer high-volume medicines subcutaneously through an automated drug delivery technology. The enFuse device leverages a hidden and retractable needle that is thinner compared to commonly used SC injection needles.
Houman Ashrafian, MD, PhD, Executive Vice President, Head of Research and Development at Sanofi:
“We are fueled by our focus on innovation and finding best-in-class solutions to help ease the burden of disease for patients. The IRAKLIA study results are a prime example of what’s driving our scientific engine. Being able to possibly bring a novel option that helps reduce time in a healthcare facility is driven by our patient and provider-centric mindset. We look forward to sharing full results and working to bring this new advancement to the multiple myeloma community.”
Additional studies evaluating Sarclisa SC formulations across different combinations and lines of therapy are ongoing. The safety and efficacy of Sarclisa SC and the enFuse device have not been evaluated by any regulatory authority outside of their approved indications. Regulatory submissions in the US and in the EU are planned during the first half of 2025.
