N2 - Mantle-cell lymphoma (MCL) remains incurable despite numerous therapeutic advances. OSU-2S, a novel nonimmunosuppressive FTY720 (Fingolimod) derivative, exhibits potent cytotoxicity in MCL cell lines and primary cells. OSU-2S increased the surface expression of CD74, a therapeutic antibody target in MCL cells. OSU-2S, in combination with anti-CD74 antibody milatuzumab, enhanced cytotoxicity in MCL. Moreover, MCL tumor antigen receptor tyrosine kinase-like orphan receptor 1 (ROR1) targeted immunonanoparticle-carrying OSU-2S (2A2-OSU-2S-ILP)-mediated selective cytotoxicity of MCL in vitro, as well as activity in a xenografted mouse model of MCL in vivo. The newly developed OSU-2S delivery using ROR1-directed immunonanoparticles provide selective targeting of OSU-2S to MCL and other ROR1+ malignancies, sparing normal B cells.
