Chidamide Combined With CHOPE Regimen for Peripheral T-cell Lymphoma Patients

Chidamide With Cyclophosphamide, Doxorubicin, Vincristine, Prednisone and Etoposide for Peripheral T Cell Lymphoma Patients : a Prospective, Randomized Controlled, Open Label, Phase II Clinical Trial

Chidamide，a novel histone deacetylase inhibitor has been approved for the treatment of relapsed or refractory peripheral T-cell lymphoma in China. The aim of this study was to observe the efficacy and safety of Chidamide With Cyclophosphamide, Doxorubicin, Vincristine, Prednisone and Etoposide for Peripheral T Cell Lymphoma Patients.
