Study Details

The purpose of this study is to compare the efficacy and safety of genotype-guided targeted agents in combination with polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisone (Pola RCHP-X) versus Pola RCHP in Chinese patients with previously untreated diffuse large B-cell lymphoma (DLBCL).

Arms

  • Experimental: Pola-RCHP-X
    Participants will receive polatuzumab vedotin 1.8 milligrams per kilogram (mg/kg) intravenously (IV) on Day2, rituximab 375 milligrams per square meter (mg/m²) IV on Day 1, cyclophosphamide 750 mg/m² IV on Day 2， doxorubicin 50 mg/m² IV on Day 2 and prednisone 100 milligrams per day (mg/day) orally (PO) on Days 2-6 of every 21-day cycle for the first cycle. For the remaining 5 cycles, they will receive Zanubrutinib 160 mg BID PO on days 1-21, or lenalidomide 25 mg/day PO on days 1-10, or decitabine 10 mg/m²/day IV on days -5 to -1 followed by standard Pola-RCHP of every 21-day cycle.
  • Active Comparator: Pola-RCHP
    Participants will receive polatuzumab vedotin 1.8 milligrams per kilogram (mg/kg) intravenously (IV) on Day2, rituximab 375 milligrams per square meter (mg/m²) IV on Day 1, cyclophosphamide 750 mg/m² IV on Day 2， doxorubicin 50 mg/m² IV on Day 2 and prednisone 100 milligrams per day (mg/day) orally (PO) on Days 2-6 of every 21-day cycle for 6 cycles.

Primary Outcome Measure

Progression-free survival（by IRC） [ Time Frame: From randomization to the first occurrence of disease progression or relapse, or death from any cause, whichever occurs earlier (up to 24 months) ]
