About this trial
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.
