Study Arms (1)
Lisatoclax Combined with R-CHOP or Pola-R-CHP
EXPERIMENTALIn Cohort 1, patients will receive standard-dose R-CHOP in combination with an initial dose of 400 mg of lisaftoclax. Each treatment cycle is 21 days. The lisaftoclax will be combined with R-CHOP at the RP2D dose level for an extension study. In Cohort 2, patients will receive standard-dose Pola-R-CHP in combination with an initial dose of 400 mg of lisaftoclax. Each treatment cycle is 21 days. The lisaftoclax will be combined with Pola-R-CHP at the RP2D dose level for an extension study.
Interventions
Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisone
Polatuzumab vedotin, Rituximab, Cyclophosphamide, Doxorubicin, Prednisone
Lisaftoclax (400 mg or 600 mg) is added from the second cycle of chemotherapy.
