Vls-101 Is a Novel Therapeutic Antibody-Drug Conjugate (ADC) Targeting Receptor Tyrosine Kinase-like Orphan Receptor 1 (ROR1) in Richter's Syndrome (RS)

ROR1 is a transmembrane receptor with tightly controlled expression during development. It is present on multiple tumor types but not on normal adult tissues. Hematological malignancies are often ROR1-positive, including chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), and diffuse large B cell lymphoma (DLBCL). Given its unique pattern of expression, ROR1 represents a tumor-specific therapeutic target. The anti-ROR1 antibody,...
