[VIRTUAL] The Anti-B-Cell Maturation Antigen (BCMA) Antibody-α-Amanitin Conjugate Hdp-101 Induces Immunogenic Cell Death and Immunologic Memory in Models of Multiple Myeloma (ASH 2020)
Using our current knowledge of ER stress activation and induction of ICD, we evaluated the combination of bortezomib and HDP-101 in H929, MM1.S, and MOLP-8 cells and primary samples. Our results support the statement that HDP-101 is a novel anti-BCMA antibody drug conjugate that shows potent activity against drug-naïve and –resistant models of myeloma, and has the potential to show enhanced anti-tumor activity against del 17 p myeloma. Moreover, its mechanism of action involves both a direct cytotoxic effect, as well as the induction of immunogenic cell death, with the latter potentially leading to immunologic memory. These studies were supported by a Leukemia & Lymphoma Society Specialized Center of Research (SCOR-12206-17).
