Chidamide for Patients With Relapse or Refractory Diffuse Large B-Cell Lymphoma and Follicular Lymphoma

Phase 2

• Conditions: Experimental
• Interventions: Drug: Chidamide

• Registration Number: NCT03410004
• Lead Sponsor: Chinese Academy of Medical Sciences

Brief Summary

Study of Chidamide as a single-agent treatment for patients with relapse or refractory Diffuse Large B-Cell Lymphoma (DLBCL) and Follicular Lymphoma (FL)

Detailed Description

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 as a single-agent treatment in patients with relapsed or refractory Diffuse Large B-Cell Lymphoma (DLBCL) and Follicular Lymphoma (FL). Moreover, the aim was to study the correlation of clinical efficacy to mutation of certain genes as well.
