Loncastuximab Tesirine (ADCT-402, Lonca) Targeting CD19

Lonca is an ADC composed of a humanized monoclonal antibody that binds to human CD19 and conjugated through a linker to a PBD-dimer toxin. Once bound to a CD19-expressing cell, Lonca is internalized into the cell where enzymes release the PBD-based warhead.
