Study Summary

This phase II trial tests whether loncastuximab tesirine works to shrink tumors in patients with B-cell malignancies that have come back (relapsed) or does not respond to treatment (refractory). Loncastuximab tesirine is a monoclonal antibody, called loncastuximab, linked to a chemotherapy drug, called tesirine. Loncastuximab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD19 receptors, and delivers tesirine to kill them.

Eligibility Criteria

Age 18+ · All Participants · 10 Total Inclusion Criteria

Mark “yes” if the following statements are true for you:
You have CD19+ relapsed/refractory PTLD.
You have been treated with a chimeric antigen receptor T-cell therapy or allogeneic transplant.
You have a male or female patient aged 18 years or older.
You have received at least 1 prior therapy for B-NHL, and no alternative therapy with a more favorable benefit/risk ratio.
You have a white blood cell count (WBC) of at least 1.0 x 10^3/uL and are not due to a lymphoma.
