Apatinib for Relapsed and Refractory Diffuse Large B Cell Lymphoma

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the efficacy and safety of Apatinib for patients with Relapsed Refractory Diffuse Large B Cell Lymphoma.

Detailed Description
-----------------
Patients with relapsed /refractory diffuse large B cell lymphoma usually have a bad prognosis. These patients cannot be treated successfully with the conventional chemotherapy of CHOP. Apatinib is a new type of oral tyrosine kinase inhibitor targeting VEGFR-2.The investigators have been proceeding this trial to evaluate the efficacy and safety of Apatinib in the patients with relapsed refractory diffuse large B cell lymphoma.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Apatinib<br>Apatinib 500mg once daily makes an initial dose and 28 days made one treatment cycle. All patients took the drug continuously until disease progression, intolerable toxicities, and patient-requested withdrawal. Appropriate supportive care were given. | Drug: Apatinib<br>* Apatinib, a novel small molecule vascular endothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase inhibitor, have shown remarkable efficacy in many solid cancers. The result of our study presented that apatinib might have a rapid, safe and high efficacy on lymphoma patients.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall Response Rate | The proportion of patients whose tumor volume has reduced to a predetermined value and can maintain the minimum time limit is the sum of complete and partial mitigation. | up to end of follow-up-phase | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression-free Survival | The time between the start of randomization and the progression of the tumor (any aspect) or (for any reason) death | up to end of follow-up-phase | 
| Overall Survival | Time from randomization to death for any reason | up to the date of death or end of follow-up-phase |
