The combination of polatuzumab vedotin with rituximab, cyclophosphamide, doxorubicin, and prednisone (pola-R-CHP) demonstrated a significant improvement in progression-free survival (PFS) over the standard-of-care (SoC) regimen of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with previously untreated diffuse large B-cell lymphoma (DLBCL), according to results of the phase III POLARIX study.
