Thalidomide Maintenance Treatment in DLBCL
- Registration Number
- NCT03016000
- Lead Sponsor
- Nanfang Hospital, Southern Medical University
- Brief Summary
This is a randomized, multi-center,phase III study to evaluate the ability of thalidomide maintenance therapy to prolong relapse-free survival in diffuse large B cell lymphoma(DLBCL).
- Detailed Description
This is a randomized, phase III study to evaluate the ability of thalidomide maintenance therapy to prolong relapse-free survival(RFS), in diffuse large B cell lymphoma(DLBCL).Patients will be enrolled after successful standard induction therapy (CR or CRu following standard R-CHOP-like therapy with 8 infusions of rituximab plus CHOP-like chemotherapy (4-8 cycles). Patients will be followed until an event occurs as defined in the protocol. To evaluate the clinical efficacy of thalidomide maintenance therapy as compared to observation in patients with DLBCL who have achieved a complete remission after appropriate first-line therapy, measured by RFS, 226 patients with DLCBL will be recruited.

Group Intervention Description Observation Observation Observation Thalidomide Thalidomide Thalidomide 50mg daily by mouth( increase 50mg after 2 weeks if tolerated until 200mg/day) until disease progression or intolerance due to AEs.The dose could be reduced if the patient experienced grade 2 or higher AEs. Does reductions for AEs were recommended (200 mg daily to 100 mg daily, 100 mg daily to 50 mg daily).In patients intolerant of 50mg/day, thalidomide discontinuation was allowed.
- Primary Outcome Measures
Name Time Method Relapse-free survival 5 years RFS was defined as the time between randomization and any documentation of relapse, death by any cause or last follow up.
- Secondary Outcome Measures
Name Time Method Overall survival 5 years OS was defined as the interval from randomization to death or the last follow-up for surviving patients.
Incidence of treatment-emergent adverse events 5 years Adverse events were classified as defined by the National Cancer Institute Common Toxicity Criteria, version 2. Safety evaluations were focused especially on neurological symptoms and the development of deep venous thrombosis (DVT).
