Testing the Addition of a New Anti-Cancer Drug, Glofitamab to Usual Chemotherapy for Burkitt and Double Hit Lymphoma

This phase II/III trial tests adding glofitamab to standard of care chemoimmunotherapy in patients with Burkitt and high grade (double hit) B- cell lymphomas that are newly diagnosed, that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Glofitamab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Obinutuzumab and rituximab are also monoclonal antibodies. They bind to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Methotrexate is in a class of medications called antimetabolites. It is also a type of antifolate. Methotrexate stops cells from using folic acid to make DNA and may kill cancer cells. Chemotherapy drugs, such as cytarabine and ifosfamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Giving glofitamab with standard of care chemotherapy may work well for the treatment of newly diagnosed, relapsed or refractory Burkitt and high grade (double hit) B- cell lymphomas.
