Active Ingredient

Loncastuximab tesirine is an antibody-drug conjugate (ADC) targeting CD19. Upon binding to CD19, loncastuximab tesirine is internalised followed by release of SG3199 via proteolytic cleavage. The released SG3199 binds to the DNA minor groove and forms highly cytotoxic DNA interstrand crosslinks, subsequently inducing cell death.
