Selinexor, Anti-PD-1 Antibody Plus Golidocitinib in R/R NKTCL

A multicenter, prospective trial to evaluate the efficacy and safety of Selinexor, anti-PD-1 antibody plus Golidocitinib in the treatment of relapsed or refractory Natural Killer / T-cell lymphoma.

This study aims to evaluate the efficacy and safety of Selinexor, anti-PD-1 antibody plus Golidocitinib in relapsed or refractory NKTCL and find the optimal treatment regimen for patients with relapsed refractory NKTCL.

Patients receive 3 cycles of Selinexor, anti-PD-1 antibody plus Golidocitinib and then PET evaluation.
