简要总结
RATIONALE: Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. It is not yet known which rituximab regimen is more effective in treating indolent non-Hodgkin's lymphoma.
PURPOSE: This randomized phase III trial is studying two different schedules of rituximab and comparing them to see how well they work in treating patients with low tumor burden indolent stage III non-Hodgkin's lymphoma or stage IV non-Hodgkin's lymphoma.
详细描述
OBJECTIVES:
Primary
- To compare time to rituximab failure between the rituximab scheduled and rituximab retreatment arms.
Secondary
- To compare the time to first cytotoxic therapy between the rituximab scheduled and rituximab retreatment arms.
- To document the rationale for beginning cytotoxic therapy; defined as chemotherapy, radiation therapy or radioimmunotherapy.
- To compare the toxicities associated with rituximab therapy between the two randomized treatment arms.

结局指标
主要结局
Time to Rituximab Failure (TTRF)
时间窗: Assessed (by restaging CT scans) 26 weeks ± 2 weeks from each rituximab treatment (including induction), counting the first rituximab dose as Day 1, until rituximab failure observed or July 17, 2013, whichever occurred first.
TTRF is defined as the time from randomization until any one of the following criteria are met, and censored at last disease assessment for cases who have not experienced failure (with the cut-off date for final analysis of 11/1/2011): 1. No response (partial response (PR) or complete response (CR)) to rituximab retreatment (Arm A treatment). 2. Time to progression \< 26 weeks from day 1 of most recent rituximab treatment. 3. Initiation of alternative therapy. 4. Inability to complete protocol therapy (due to adverse events, patient preference, or any other reason, including death).
次要结局
- Time to First Cytotoxic Therapy (TTFC)(Assessed every 13 weeks until rituximab failure observed or August 2013, whichever occurred first.)
- Overall Health-related Quality of Life (HRQL) at 6 Month After Randomization(Assessed at baseline and 6 months after randomization.)
