Chidamide+Decitabine Plus Anti-PD-1 Antibody for Patients With R/R cHL Who Are Transplant-ineligible or Refused Transplant.

The prognosis of refractory or early-relapsed lymphoma is poor, and it is even worse for those who are not eligible or refuse transplantation. Although many salvage regimens have been developed, there is no standard of care. Preliminary clinical observations have shown that Chidamide +Decitabine plus Anti-PD-1 Antibody might be beneficial for these patients. Brentuximab Vedotin or Bendamustine plus Anti-PD-1 Antibody are both standard regimens.The combination of Brentuximab Vedotin, Bendamustine and Anti-PD-1 Antibody may be another effective regimen. This open-label, randomized, phase 2 study aims to evaluate the efficacy of Chidamide+Decitabine plus anti-PD-1 antibody and Brentuximab Vedotin + Bendamustine plus Anti-PD-1 Antibody, in patients with classical Hodgkin lymphoma who are transplant-ineligible or refused transplant . The primary objective of the study is to evaluate the progression free survival. The key secondary end points are complete response rate, objective response rate and the safety.
