Parsaclisib Plus the Standard Drug Therapy in Patients With Newly Diagnosed, High Risk Diffuse Large B-cell Lymphoma

This phase I/Ib trial studies the side effects and best dose of parsaclisib with or without polatuzumab-vedotin (Pola) plus the standard drug therapy (rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and prednisone \[PaR-CHOP\]) and to see how well they work compared with R-CHOP alone in treating patients with newly diagnosed, high risk diffuse large B-cell lymphoma. Parsaclisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Polatuzumab-vedotin is a monoclonal antibody, called polatuzumab, linked to a chemotherapy drug, called vedotin. Polatuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as anti-CD79b receptors, and delivers vedotin to kill them. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin hydrochloride, and vincristine sulfate, 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. Anti-inflammatory drugs, such as prednisone, lower the body's immune response and are used with other drugs in the treatment of some types of cancer. It is not yet known if giving parsaclisib and R-CHOP together works better than R-CHOP alone in treating patients with high risk diffuse large B-cell lymphoma.

Loncastuximab Tesirine and Rituximab Followed by DA-EPOCH-R for Treating Patients With High-Risk Diffuse Large B-cell Lymphoma

This phase II trial evaluates whether loncastuximab tesirine and rituximab followed by dose-adjusted doxorubicin, etoposide, vincristine, cyclophosphamide, and prednisone works to treat patients with high risk diffuse large B-cell lymphoma. Loncastuximab tesirine is a monoclonal antibody called loncastuximab, linked to a drug called tesirine. It is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD19 receptors, and delivers tesirine to kill them. Rituximab 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. Chemotherapy drugs such as doxorubicin, vincristine, and cyclophosphamide 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. 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. 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. Giving loncastuximab tesirine and rituximab in combination with dose-adjusted doxorubicin, etoposide, vincristine, cyclophosphamide, and prednisone may be more effective at treating high risk diffuse large B-cell lymphoma patients than standard treatments.
