Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

OUTLINE: This is a phase I, dose-escalation study of parsaclisib, and safety lead-in of pola.

ARM I (PHASE I AND DOSE EXPANSION): Patients receive parsaclisib orally (PO) once daily (QD) on days 1-10 or 1-14, rituximab intravenously (IV) or biosimilar substitute, cyclophosphamide IV over 30 minutes, doxorubicin hydrochloride IV, and vincristine sulfate IV over 15 minutes on day 1. Patients also receive prednisone PO on days 1-5 and pegfilgrastim subcutaneously (SC) or biosimilar substitute on day 2. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

ARM II (PHASE I AND POLA SAFETY LEAD-IN): Patients receive parsaclisib PO once daily QD on days 1-10 or 1-14, polatuzumab vedotin IV over 90 minutes, rituximab IV or biosimilar substitute, cyclophosphamide IV over 30 minutes, doxorubicin hydrochloride IV, and vincristine sulfate IV over 15 minutes on day 1. Patients also receive prednisone PO on days 1-5 and pegfilgrastim SC or biosimilar substitute on day 2. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months during year 1 and every 4 months during year 2. Patients who experience disease progression before the end of year 2 are followed up every 6 months until 5 years after registration.
