This is a prospective, multicenter, phase III study of Tucidinostat, Azacitidine combined with CHOP versus CHOP in patients with untreated peripheral T-cell lymphoma

Tucidinostat, a novel histone deacetylase inhibitor has been approved for the treatment of relapsed or refractory peripheral T-cell lymphoma in China. Azacytidine is a hypomethylating agent. The aim of this study is to compare the efficacy and safety of azacytidine, tucidinostat combined with CHOP regimen and classical CHOP regimen in the treatment of primary PTCL
