About the trial
A double-blind, randomized phase II comparative trial will evaluate the superiority of the investigational treatment (tirabrutinib maintenance therapy) over standard care (observation with placebo) in terms of progression-free survival in patients with newly diagnosed primary central nervous system lymphoma (PCNSL) who have achieved complete response (CR or CRu) following induction therapy with high-dose methotrexate (HD-MTX)-based chemotherapy and have not undergone consolidative whole-brain irradiation. Participants will: Take protocol drug tirabrutinib or a placebo every day until disease progression or experience of unacceptable toxicity. Visit the clinic once every 4 weeks for checkups and tests, as well as protocol drug prescription.
