About this study

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.
