Patients with relapsed /refractory aggressive B cell lymphoma usually have a poor prognosis. These patients cannot be treated successfully or tolered with the conventional chemotherapy. Epigenetic changes in B-cell lymphoma. Thus, epigenetic agents may offer potential improvment of clinical outcomes. Chidamide is a new type of oral histone deacetylase inhibitor. Our exploratory research found that Chidamide was effect in some relapsed /refractory B cell lymphoma patients~. Thus, we will evaluate the efficacy and safety of Chidamide in the patients with aggressive relapsed refractory B cell lymphoma failed from second line chemotherapy.
This is a prospective phase II clinical trial to observe the efficacy and safety of Chidamide as a single-agent treatment in patients with relapsed or refractory B-cell Non-Hodgkin's Lymphoma (NHL).
