Selinexor in Combination With R-CHOP as the First-line Therapy for TP53-mutated DLBCL Patients (Smart Trial)

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.
