Selinexor, High-dose Methotrexate, and Rituximab Combined With Radiotherapy for Newly Diagnosed, Transplant-ineligible Patients With Central Nervous System Lymphoma: An Open-label, Single-arm, Multicenter Phase II Study

• Status: RECRUITING
• Trial end date: 2028-12-31

Summary

This phase II clinical trial is designed to evaluate a novel combination treatment for patients with newly diagnosed central nervous system lymphoma (CNSL) who are not candidates for stem cell transplantation. The study will assess the safety and effectiveness of combining selinexor (an oral selective nuclear export inhibitor) with high-dose methotrexate and rituximab chemotherapy, followed by low-dose whole-brain radiotherapy (WBRT). Selinexor has shown promise in enhancing the effects of chemotherapy and radiation in blood cancers.

Patients enrolled in this open-label, single-arm, multicenter study will receive up to six 21-day treatment cycles. Those who respond well will undergo reduced-dose WBRT and continue selinexor as maintenance therapy. The study will measure how many patients respond to the treatment (overall response rate), how long the response lasts (progression-free survival), overall survival, and safety.

This research aims to provide a less toxic and more effective option for treating CNSL in patients who are older or medically unfit for transplantation.
