Thiotepa in Combination With Pirtobrutinib (a BTK Inhibitor) and Sintilimab (a PD-1 Inhibitor) for Frail or Relapsed/Refractory Primary or Secondary Central Nervous System Lymphoma

This is a prospective, single-Arm, phase II clinical study evaluating the efficacy and safety of thiotepa in combination with pirtobrutinib (a BTK Inhibitor) and sintilimab (a PD-1 Inhibitor) for frail or relapsed/refractory primary or secondary central nervous system lymphoma.It includes screening phase， induction therapy phase, and maintenance therapy phase.The screening period is defined as within 14 days prior to the first dose.Induction Treatment Phase: Enrolled subjects will receive a combination regimen of thiotepa, pirtobrutinib, and sintilimab. Treatment is administered in 21-day cycles for up to 6 cycles. Patients who achieve a disease response may proceed to consolidation therapy with either autologous hematopoietic stem cell transplantation or whole-brain radiotherapy at the investigator's discretion.Maintenance Treatment Phase: For patients who do not receive consolidation therapy with autologous transplantation or whole-brain radiotherapy, maintenance treatment with pirtobrutinib plus sintilimab will be initiated (for up to 1 year). Patients who receive any consolidation therapy will not proceed to maintenance treatment.Treatment response will be assessed throughout the study using the International Primary CNS Lymphoma Collaborative Group (IPCG) criteria. The trial will monitor patient survival data, objective response rate (ORR), and safety parameters.Upon discontinuation of study treatment or completion of the 1-year treatment period, subjects will enter the …
