Sanofi to present clinical data reinforcing commitment to scientific innovation across blood cancers and rare blood disorders at ASH 2023

Cambridge, M.A., November 7, 2023. New data from across Sanofi’s oncology and rare blood disorders portfolios will be featured in 25 clinical research presentations, including seven oral presentations, at the 65th American Society of Hematology (ASH) Annual Meeting & Exposition taking place December 9-12, 2023 in San Diego. These data demonstrate our commitment to scientific innovation and the potential of our investigational and approved therapies to address unmet needs across a spectrum of hematologic conditions with limited treatment options.     

Brian Foard
Head, Specialty Care North America
“The spectrum of data Sanofi will present at ASH has the potential to reframe the possibilities for millions of patients living with hematologic conditions. New data for ALTUVIIIO, a first-in-class, high-sustained factor VIII replacement therapy, demonstrate our ambition to change treatment expectations for adults and children living with hemophilia A. Additionally, we continue to explore Sarclisa in combination with standard-of-care therapies in earlier lines of treatment for patients with newly diagnosed multiple myeloma.”

New data from the Phase 3 IsKia clinical trial, in partnership with the European Myeloma Network (EMN), evaluating the investigational combination of Sarclisa® (isatuximab-irfc) added to the standard-of-care regimen carfilzomib, lenalidomide and dexamethasone (KRd) in newly-diagnosed multiple myeloma (NDMM) are being presented. IsKia has the potential to provide insights in an area of unmet need in NDMM patients. 

Presentations of the Sanofi oncology pipeline at ASH include updated efficacy and safety results from an open-label, first-in-human, dose-escalation study of an investigational CD123 targeting Natural Killer Cell Engager (NKCE). Results investigating SAR443579 as a monotherapy for the treatment of blood cancers with high unmet needs, including relapsed or refractory acute myeloid leukemia, B-cell acute lymphoblastic leukemia and high-risk myelodysplasia show data across all dose levels tested. Observed clinical remissions will also be presented.

Paul Rowe
Head of Medical Affairs, Specialty Care North America
“Our research highlights advances for our innovative treatments in hematology and our ambition in immunology. We are excited to share findings from our robust pipeline and investigational assets, including new data for our CD123 targeting natural killer cell engager in several hematological malignancies, and our BTK inhibitor in immune thrombocytopenia with a new mechanism of action for this condition. We are committed to pursuing scientific innovation and for difficult-to-treat hematologic diseases to transform care and improve outcomes.”

In hemophilia, our focus is to evolve treatment expectations for patients. Data from the Phase 3 XTEND-Kids trial evaluating factor activity levels in children younger than 12 years of age receiving once-weekly ALTUVIIIO® [Antihemophilic Factor (Recombinant), Fc-VWF-XTEN Fusion Protein-ehtl] will be presented. Additional qualitative insights from this trial based on the caregiver perspective will detail the potential impact of treatment with ALTUVIIIO for both children less than 12 years of age and their caregivers.

New results from Part B of the Phase 1/2 LUNA study for rilzabrutinib, a new and investigational Bruton’s tyrosine kinase (BTK) inhibition therapy for immune thrombocytopenia (ITP), will show encouraging data regarding the effect on platelet levels, safety profile, and quality of life measures in patients with relapsed ITP. ITP is a serious, acquired autoimmune blood disorder characterized by autoantibody-mediated platelet destruction and impaired platelet production, leading to thrombocytopenia and an increased risk of life-threatening bleeding episodes (like intracranial hemorrhage). Patients with ITP can experience quality-of-life impairments such as fatigue and cognitive impairment, and despite current treatment options, unmet needs remain for these patients. Rilzabrutinib is currently under clinical investigation and has not been evaluated by any regulatory authority.

An abstract evaluating the potential cost effectiveness of the U.S. Sanofi Promise Warranty Program for Cablivi® (caplacizumab-yhdp) will be shared. Cablivi is the first and only treatment for adults with acquired thrombotic thrombocytopenia purpura (aTTP) in combination with plasma exchange and immunosuppression.

A combined safety analysis from the two Phase 3 studies, CARDINAL and CADENZA, of Enjaymo® (sutimilab-jome) in adults with CAD will be presented. CAD is a rare autoimmune hemolytic anemia, with over 90% of patients suffering from uncontrolled complement-mediated hemolysis where part of the body’s immune system mistakenly destroys healthy red blood cells. Enjaymo is the first approved treatment for people with CAD in the U.S., EU, Switzerland, South Korea and Japan.

About Sarclisa
Sarclisa is a monoclonal antibody that binds to a specific epitope on the CD38 receptor on multiple myeloma (MM) cells, inducing distinct antitumor activity. It is designed to work through multiple mechanisms of action including programmed tumor cell death (apoptosis) and immunomodulatory activity. CD38 is highly and uniformly expressed on the surface of MM cells, making it a potential target for antibody-based therapeutics such as Sarclisa.

Based on the Phase 3 ICARIA-MM study, Sarclisa is approved in 52 countries, including the U.S. and EU, in combination with pomalidomide and dexamethasone for the treatment of certain patients with relapsed refractory MM (RRMM) who have received ≥2 prior therapies, including lenalidomide and a proteasome inhibitor. Based on the Phase 3 IKEMA study, Sarclisa is also approved in multiple countries in combination with carfilzomib and dexamethasone, including in the U.S. for the treatment of patients with RRMM who have received 1–3 prior lines of therapy and in the European Union for patients with MM who have received at least 1 prior therapy. In the U.S., the generic name for Sarclisa is isatuximab-irfc, with irfc as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. Food and Drug Administration (FDA).

Sarclisa continues to be evaluated in multiple ongoing Phase 3 clinical trials in combination with current standard treatments across the MM treatment continuum. It is also under investigation for the treatment of other hematologic malignancies, and its safety and efficacy have not been evaluated by any regulatory authority outside of its approved indication.

For more information on Sarclisa clinical trials, please visit www.clinicaltrials.gov.

Contact your doctor immediately if symptoms of excessive bruising, excessive bleeding, or major bleeding occur. Signs and symptoms of bleeding include: pain, swelling or discomfort, prolonged bleeding from cuts, increased menstrual flow or vaginal bleeding, nosebleeds, bleeding of gums from brushing, unusual bleeding or bruising, red or dark brown urine, red or tar black stools, headache, dizziness, or weakness.

You may have a higher risk of bleeding if you have a bleeding disorder (i.e. hemophilia) or if you take other medicines that increase your risk of bleeding such as anti-coagulants and anti-platelet agents. CABLIVI should be stopped for 7 days before surgery or any medical or dental procedure. Talk to your doctor before you stop taking CABLIVI.

The most common side effects include nosebleed, headache and bleeding gums.

Tell your doctor if you have any side effect that bothers you or that does not go away. These are not all the possible side effects of CABLIVI. Call your doctor for medical advice about side effects.

Please see accompanying full Prescribing Information.
