R-PMDT Regimen in Newly Diagnosed PCNSL
2026年5月17日 更新者：Zou Dehui
A Prospective, Multicenter, Open-Label, Single-Arm, Phase 2 Study to Evaluate the Efficacy and Safety of Rituximab, Pirtobrutinib, High-Dose Methotrexate, Dexamethasone, and Thiotepa (R-PMDT) in Patients With Newly Diagnosed Primary Central Nervous System Lymphoma
A total of six cycles of the R-PMDT regimen (rituximab, pirtobrutinib, high-dose methotrexate, dexamethasone, and thiotepa) will be administered to patients with newly diagnosed primary central nervous system lymphoma (PCNSL).
The primary objective is to assess the overall response rate (ORR) of R-PMDT.
Secondary objectives include evaluating the complete response rate, progression-free survival (PFS), overall survival (OS), and safety.

详细说明
In this prospective, multicenter, open-label, single-arm phase 2 clinical trial, eligible patients with newly diagnosed primary central nervous system lymphoma (PCNSL) will receive six cycles of the R-PMDT regimen.
The R-PMDT regimen is administered as follows: rituximab (R, 375 mg/m²) is given as an intravenous infusion on day 0; methotrexate (M, 3.5 g/m²) is administered as a 3-hour intravenous infusion on day 1, with dose adjustment based on pre-treatment creatinine clearance; dexamethasone (D, 20 mg) is given intravenously on days 1-4; thiotepa (T, 30 mg/m²) is administered intravenously on day 1; and pirtobrutinib (P, 200 mg once daily) is taken orally on days 4-21.
After completion of six cycles, depending on the investigator's decision, patients may receive consolidation or maintenance therapy, including but not limited to autologous hematopoietic stem cell transplantation, radiotherapy, or pirtobrutinib maintenance.
The primary objective is to assess the overall response rate (ORR) of R-PMDT.
Secondary objectives include evaluation of the complete response rate, progression-free survival (PFS), overall survival (OS), and safety.
