Central Nervous System Lymphoma
Conditions
Brief summary
This study will evaluate the efficacy, safety and patient reported outcomes of chidamide 20 mg biw PO day1-14 and rituximab 375 mg/m2 IV given on day 1 and methotrexate 3.5g/m2 IV given on day 2 of every 21-day cycle for 6 cycles in untreated patients with primary central nervous system lymphoma. The primary study endpoint will be complete response (CR) rate as assessed by the investigator. The hypothesis is previously untreated patients with primary central nervous system lymphoma could achieve a CR rate of 80% with C-R-HDMTX.
