Study Summary

This phase II trial studies the safety and how well of loncastuximab tesirine when given together with mosunetuzumab works in treating patients with diffuse large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Loncastuximab tesirine is a monoclonal antibody, loncastuximab, linked to a toxic agent called tesirine. Loncastuximab attaches to anti-CD19 cancer cells in a targeted way and delivers tesirine to kill them. Mosunetuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving loncastuximab tesirine with mosunetuzumab may help treat patients with relapsed or refractory diffuse large B-cell lymphoma.

Primary Outcome

Defined as any toxicity occurring during the first cycle of treatment for patients enrolled on DL 1, or during the first two cycles of treatment for patients enrolled on DL -1, within at most one out of six patients treated. Will be conducted per the rolling six design.
