Loncastuximab tesirine, sold under the brand name Zynlonta, is a monoclonal antibody conjugate medication used to treat large B-cell lymphoma and high-grade B-cell lymphoma.[1][2] It is an antibody-drug conjugate (ADC) composed of a humanized antibody targeting the protein CD19.[1]

The most common side effects include increased levels of gamma-glutamyltransferase (GGT, a liver enzyme), neutropenia (low levels of neutrophils, a type of white blood cell), tiredness, anemia (low levels of red blood cells), thrombocytopenia (low levels of blood platelets), nausea (feeling sick), peripheral edema (swelling due to fluid retention, especially of the ankles and feet) and rash.[2]

Loncastuximab tesirine was approved for medical use in the United States in April 2021,[1][3][4] and in the European Union in December 2022.[2] The US Food and Drug Administration (FDA) considers it to be a first-in-class medication.[5]
