설명

Inclusion Criteria:

  • Age ≥18 years.
  • Histologically confirmed diffuse large B-cell lymphoma (DLBCL) according to the 2016 WHO classification with BCL-2 positivity by immunohistochemistry (defined as BCL-2 expression ≥30%).

  • At least one measurable or evaluable lesion according to the Lugano 2014 lymphoma response criteria.
  • Adequate bone marrow, hepatic, and renal function.
  • Ability to understand and willingness to voluntarily sign a written informed consent form.

Exclusion Criteria:

  • Central nervous system (CNS) involvement by lymphoma, primary CNS lymphoma, or leukemic phase lymphoma.
  • Prior intolerance to BCL-2 inhibitors and chidamide, or disease refractory to or relapsed after treatment with both agents.
  • Known hypersensitivity to any component of the study drugs or their analogs.
  • Prior allogeneic hematopoietic stem cell transplantation within 6 months before the first dose, active graft-versus-host disease (GvHD), or requirement for immunosuppressive therapy within 28 days prior to study treatment.
  • Clinically significant active cardiovascular disease.
  • Uncontrolled or clinically unstable infection requiring parenteral antibacterial, antiviral, or antifungal therapy within 7 days before the first dose of study treatment.
  • Pregnant or breastfeeding women.
  • Active human immunodeficiency virus (HIV) infection and/or acquired immunodeficiency syndrome (AIDS).
  • Malabsorption syndrome or other conditions that may interfere with enteral administration or absorption of study drugs.
  • Any other medical, psychiatric, or social condition that, in the investigator's judgment, would make the subject inappropriate for participation in this study.

실험적: Lisaftoclax in combination with chidamide and rituximab
Patients will receive lisaftoclax orally once daily on Days 1-14 of each 21-day cycle for up to 6 cycles, with daily dose ramp-up during Cycle 1. Chidamide will be administered orally at 20 mg on Days 1, 4, 8, and 11 of each cycle, and rituximab will be administered intravenously at 375 mg/m² on Day 1 of each cycle.
Lisaftoclax will be administered orally once daily on Days 1-14 of each 21-day cycle for up to 6 cycles. During Cycle 1, a daily dose ramp-up schedule will be used. In the 600 mg cohort, participants will receive 200 mg on Day 1, 400 mg on Day 2, and 600 mg on Day 3, followed by 600 mg once daily on Days 4-14. In the 800 mg cohort, participants will receive 200 mg on Day 1, 400 mg on Day 2, 600 mg on Day 3, and 800 mg on Day 4, followed by 800 mg once daily on Days 5-14. From Cycles 2-6, participants will receive lisaftoclax at the target dose (600 mg or 800 mg) once daily on Days 1-14.
Chidamide will be administered orally at a dose of 20 mg on Days 1, 4, 8, and 11 of each 21-day cycle for up to 6 cycles.
Rituximab will be administered intravenously at a dose of 375 mg/m² on Day 1 of each 21-day cycle for up to 6 cycles.
