Title: NOVEL MULTIFUNCTIONAL TETRAVALENT CD38 NKP46 FLEX-NK ENGAGERS ACTIVELY TARGET AND KILL MULTIPLE MYELOMA CELLS
Session Title: Poster session
Session date and time: Friday, June 10 2022 – 16:30 – 17:45 CEST
Final Abstract Code: P842

Summary: CYT-338 is a tetravalent IgG1-like multifunctional NK cell engager antibody with a novel FLEX-linker that simultaneously binds CD38-expressing cells and NK cells via the activating receptor NKp46. CYT-338 pharmacokinetics and pharmacodynamics was studied using in vitro and in vivo multiple myeloma models. CYT-338 showed 3-fold higher dose-dependent binding to CD38 expressing MM cell lines compared to daratumumab. Epitope mapping studies indicated that CYT-338 binds to a different CD38 epitope compared to daratumumab. CYT-338 showed greater dose dependent NK cell redirected cytolysis, degranulation, and cytokine production against MM1S cells compared to daratumumab. CYT-338 showed minimal immune subset depletion, NK cell fratricide, and cytokine release compared to daratumumab in vitro. CYT-338 showed tumor growth inhibition and improved survival in in vivo models of multiple myeloma. These results support further development of CYT-338 as a therapeutic for targeting CD38 expressing multiple myeloma cells distinct from daratumumab.

About CD38
Cluster of differentiation 38 (CD38) is a type II receptor membrane glycoprotein that plays a role in cell adhesion, migration, and signal transduction. Additionally, CD38 is an ectoenzyme involved in generation of nucleotide metabolites, such as ADP-Ribose that regulate cell metabolism. CD38 is highly expressed in multiple myeloma (MM) on malignant plasma cells and is also moderately expressed on normal T, B, NK and myeloid cells. Antibodies targeting CD38, such as daratumumab and isatuximab, are FDA approved for the treatment of MM as monotherapy and in combination.
