Overview

This combination regimen is a multi-drug therapy being investigated for the treatment of relapsed or refractory primary or secondary central nervous system lymphoma (r/r CNSL). The protocol, specifically studied in the SELINA trial led by Ruijin Hospital, combines two targeted agents with a flexible chemotherapy backbone. **Selinexor** is a selective inhibitor of nuclear export (SINE) that blocks Exportin 1 (XPO1), leading to the nuclear accumulation of tumor suppressor proteins. **Orelabrutinib** is a highly selective, irreversible Bruton's tyrosine kinase (BTK) inhibitor that disrupts B-cell receptor signaling pathways essential for lymphoma cell survival. The chemotherapy component consists of either **methotrexate** (an antimetabolite inhibiting dihydrofolate reductase), **thiotepa**, or **temozolomide** (both DNA alkylating agents), chosen based on patient tolerance and prior resistance. This combination aims to improve objective response rates by targeting multiple oncogenic drivers and overcoming the blood-brain barrier.
