PRIMARY OBJECTIVE: I. Determine the safety, toxicity profile and recommended phase 2 dose (RP2D) of zanubrutinib in combination with R-CHOP (ZaR-CHOP) for patients with previously untreated diffuse large B-cell lymphoma (DLBCL). SECONDARY OBJECTIVES: I. Determine the objective response rate (ORR) (complete and partial responses), progression-free survival (PFS) and overall survival (OS) of ZaR-CHOP in patients treated at the RP2D. II. Provide descriptive data on treatment exposure to zanubrutinib and R-CHOP including treatment discontinuation rate and relative dose intensity. OUTLINE: This is a dose de-escalation study of zanubrutinib and fixed-dose R-CHOP regimen followed by a dose-expansion study. Patients receive zanubrutinib orally (PO) once or twice daily on days 1-21, rituximab intravenously (IV) on day 1, cyclophosphamide IV on day 1, doxorubicin hydrochloride IV on day 1, vincristine sulfate IV on day 1, and prednisone PO QD on days 1-5. 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 every 6 months for 2 years.
