Phase 1/2RecruitingOHSU Knight Cancer InstituteNCT06249191Data as of May 2026

Treatment: Cyclophosphamide · Doxorubicin · Etoposide · Mosunetuzumab · Prednisone · VincristineThis phase Ib/II clinical trial tests the safety, side effects, and effectiveness of mosunetuzumab with chemotherapy for the treatment of patients with untreated, c-Myc rearrangement positive, high grade B cell lymphoma or diffuse large B cell lymphoma. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as mosunetuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as etoposide, doxorubicin, vincristine, cyclophosphamide and prednisone work in different ways to stop the growth of cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving mosunetuzumab with chemotherapy may be safe, tolerable and/or effective in treating patients with untreated, c-Myc rearrangement positive, high grade B cell lymphoma or diffuse large B cell lymphoma.
