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.
CD19 is an ideal target for an ADC approach
CD19 is highly expressed in a range of B-cell hematological tumors, including certain types of lymphoma and leukemia, while its expression in healthy tissue is restricted.
Lonca is the focus of the LOTIS Clinical Development Program
In clinical trials, lead candidate Lonca has demonstrated significant single-agent clinical activity across a broad population of patients with relapsed or refractory diffuse large B-cell, mantle cell, and follicular lymphomas.
