What this Trial Is About

This phase 1 pilot study examines the feasibility and safety of mosunetuzumab after autologous stem cell transplant for patients with aggressive B cell lymphomas. Mosunetuzumab is an antibody that has been engineered to attach to two target cells in the immune system: T cells that normally perform tasks like killing virus-infected cells, and cancerous B cells. Mosunetuzumab has been designed to direct these T cells to kill the cancerous B cells instead.
