Loncastuximab tesirine

What are the uses of this medicine?

• Loncastuximab tesirine-lpyl (Zynlonta) is used to treat adults with certain types of large B-cell lymphoma that has come back (relapsed) or that did not respond to previous treatment (refractory), who have already received two or more treatments for their cancer.

How does this medicine work?

• Loncastuximab tesirine-lpyl is an antibody-drug conjugate (ADC) targeting CD19.
• The monoclonal IgG1 kappa antibody component binds to human CD19, a transmembrane protein expressed on the surface of cells of B-lineage origin.
• The small molecule component is SG3199, a PBD dimer and alkylating agent.
• Upon binding to CD19, loncastuximab tesirine-lpyl is internalized 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. Loncastuximab tesirine-lpyl had anticancer activity in animal models of lymphoma.
