Sanofi to showcase new data from oncology portfolio spanning marketed products and investigational compounds at ASH 2022 Four Sarclisa ® (isatuximab) oral presentations and 11 posters featuring cutting-edge investigational and marketed therapies to be presented December 2 , 2022 . Data featured at the 64 th American Society of Hematology (ASH) Annual Meeting & Exposition from December 10-13, 2022, reinforce Sanofi’s commitment to transforming care for people living with multiple myeloma (MM) and other difficult-to-treat blood cancers. Peter C. Adamson , MD Global Head of Oncology Development “ Data to be presented at this year’s ASH Meeting demonstrate our commitment to improving the outcome for patients with cancer . This includes presentations for Sarclisa , an anti- CD38 antibody of choice for patients with multiple myeloma and a cornerstone of our strategy to broaden our portfolio in hematologic malignancies . W e are proud to be advancing knowledge and the treatment of patients with multiple myeloma , by sharing emerging data from our research efforts . ” The first Sarclisa oral presentation will detail results from a subgroup analysis of the Phase 3 IKEMA trial, which in May 2022 reported updated median progression-free survival results in combination with carfilzomib and dexamethasone. This new analysis compared patients with early versus late relapse. The second Sarclisa oral presentation highlights updated longer-term efficacy data following subsequent therapy in the pivotal Phase 3 ICARIA-MM trial. It is critical to advance scientific understanding of how individuals who relapse early will respond to subsequent lines of therapy because the earlier a person relapses, the more difficult they can be to treat. Sanofi is also presenting multiple abstracts from its investigational early pipeline of cutting-edge compounds, such as an open-label, first-in-human, dose-escalation study of Natural Killer Cell Engager (NKCE) SAR443579 as a monotherapy for the treatment of relapsed or refractory acute myeloid leukemia, B-cell acute lymphoblastic leukemia or high-risk myelodysplasia. Another abstract will highlight the potential of SAR’514, an anti-B cell Maturation Antigen (BCMA) NKCE, for controlling MM tumors in vivo. Since 2019, Sanofi’s oncology pipeline has doubled, with a dozen next-generation, potential first- or best-in-class compounds entering clinical trials. Much of this growth is a result of an acceleration of in-house research and development capabilities, as well as building external partnerships, particularly in early portfolio, including for MM and other hematologic malignancies.
