Outcome Measures

Primary Outcomes (2)

  • Dose-limiting toxicity (DLT) for Phase 1b

    To identify the DLT

    The first cycle (each cycle is 21 days) after lisaftoclax administration.

  • Complete response rate (CRR) for Phase 2

    The proportion of patients who achieve complete response (CR)

    Up to 8 cycles (each cycle is 21 days)

Secondary Outcomes (4)

  • Overall response rate (ORR)

    Up to 8 cycles (each cycle is 21 days)

  • Duration of Response (DOR)

    Up to 5 years

  • Progression-free survival (PFS)

    Up to 5 years

  • Overall survival (OS)

    Up to 5 years

Study Arms (1)

Lisatoclax Combined with R-CHOP or Pola-R-CHP

EXPERIMENTAL

In 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.
