Arm group label: Selinexor in combination with R-CHOP

Other name: R-CHOP regimen

Summary: This is a prospective, single-arm, multi-center, phase II clinical trial to evaluate the efficacy and safety of selinexor in combination with R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisone) followed by selinexor maintenance for untreated TP53-mutated diffuse large B-cell lymphoma (DLBCL) patients.

Detailed description: The purpose of this phase II clinical trial is to evaluate the efficacy and safety of selinexor in combination with R-CHOP for untreated TP53-mutated DLBCL patients. The induction phase consisted of 8 cycles of selinexor in combination with R-CHOP. After 8 cycles of induction therapy, if the response is assessed as complete remission (CR), maintenance therapy with selinexor will be conducted. The primary endpoint is complete response rate.
