Phase 2 Response-Adapted Study of Ibrutinib With Temozolomide, Etoposide, Liposomal Doxorubicin, Dexamethasone, Rituximab (TEDDI-R) for Secondary CNS Lymphoma

Background: Secondary CNS lymphomas (SCNSL) are aggressive and there are few treatment options. CNSLs often have underlying chronic active B-cell receptor signaling that responds to BTK inhibitors, but the response duration is short. TEDDI-R achieves durable remissions in primary DLBCL of the CNS (PCNSL), but the molecular profile of SCNSL tumors that are BTK-responsive is unknown. We present results from an ongoing response-adapted study of ibrutinib with TEDD-R in SCNSL [NCT03964090].
