Selinexor With ICE Chemotherapy in Secondary Central Nervous System Involving B-cell Non-Hodgkin Lymphoma

Secondary involvement of the central nervous system (CNS), such as CNS relapse after treatment or progression during treatment, is a rare but deadly occurrence in patients with B-cell non-Hodgkin lymphoma (NHL), particularly in cases of diffuse large B-cell lymphoma (DLBCL) and transformed follicular lymphoma (FL). Despite the grim prognosis associated with secondary CNS involvement, no definitive treatment strategy exists. Selinexor®, an oral, first-in-class, potent selective inhibitor of nuclear export that binds to XPO1, leads to the nuclear retention of tumor suppressor and growth regulator proteins, as well as topoisomerase II enzymes, thereby restoring their functions. Preclinical studies have also shown that selinexor can sensitize cancer cells to topoisomerase inhibitors, alkylating agents, and steroids. Selinexor has been approved by the Food and Drug Administration for relapsed or refractory DLBCL. We hypothesize that selinexor could work synergistically with ifosfamide (an alkylating agent) and etoposide (a topoisomerase II inhibitor) in the ifosfamide, carboplatin, and etoposide (ICE) regimen. High-dose dexamethasone was added to this regimen to enhance the efficacy of ICE as a salvage regimen for secondary CNS involvement, due to its ability to cross the blood-brain barrier. This phase I/II study aims to evaluate the efficacy and safety of selinexor in combination with ifosfamide, carboplatin, etoposide (ICE), and dexamethasone in patients with relapsed or refractory B-cell non-Hodgkin lymphoma with secondary CNS involvement.
