Diffuse Large B-Cell Lymphoma, Relapsed and refractory, Histone deacetylase inhibitor, Chidamide
Brief summary
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).
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.
Interventions
30mg , Oral twice a week(with an interval of no less than 3 days,;e.g. Monday and Thursday,Tuesday and Friday) until disease progression or unacceptable toxicity develops
20mg/m2, IV on day 1 of each 14 day cycle until disease progression or unacceptable toxicity develops, up to 12 cycles
20mg/m2, IV on day 1 of each 14 day cycle(Note:for patients who can not afford the liposomal doxorubicin,may be replaced into mitoxantrone 8mg/m2, IV on day1 of each 14 day cycle) until disease progression or unacceptable toxicity develops, up to 12 cycles
10mg/m2 , IV on day 1-5 of each 14 day cycle until disease progression or unacceptable toxicity develops, up to 12 cycles
100mg,Oral at night on each day until disease progression or unacceptable toxicity develops, up to 24 weeks
