March 31, 2020 updated by: Yanyan Liu, Henan Cancer Hospital

The Efficacy and Safety of Chidamide Combined With VDDT Regimen（Vinorelbine，Liposomal Doxorubicin，Dexamethasone and Thalidomide） in Relapse and Refractory Patients With Diffuse Large B Cell Lymphoma

This is a prospective phase II clinical trial to observe the efficacy and safety of Chidamide combined with VDDT(vinorelbine，liposomal doxorubicin，dexamethasone and thalidomide) in relapsed and refractory patients with diffuse large B-cell lymphoma(DLBCL).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

There are one third of diffuse large B-cell Lymphoma patients suffering relapse and refractory, which are the major cause of death among these patients. Vinorelbine，liposomal doxorubicin，mitoxantrone, dexamethasone and thalidomide have been used in the therapy of patients who failed with Second-line treatments in our center. This regimen is well tolerated but the effect needs to be improved. Chidamide，a histone deacetylase inhibitor has been approved for the treatment of refractory T-cell lymphoma in China. The goal is to assess the efficacy and safety of chidamide combined with VDDT（vinorelbine，liposomal doxorubicin，dexamethasone and thalidomide） in relapse and refractory patients with diffuse large B-cell Lymphoma.

Outcome Measure

from date of first day of treatment to the date of first documented
