简要总结
RATIONALE: Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Combinations of biological substances in denileukin diftitox may be able to carry cancer-killing substances directly to cancer cells. Giving rituximab together with denileukin diftitox may kill more cancer cells.
PURPOSE: This phase II trial is studying how well giving rituximab together with denileukin diftitox works in treating patients with previously untreated stage III or stage IV follicular B-cell non-Hodgkin's lymphoma.
详细描述
OBJECTIVES:
Primary
- Determine the response rate (complete response [CR], unconfirmed CR, and partial response) in patients with previously untreated stage III or IV follicular B-cell non-Hodgkin's lymphoma treated with rituximab and denileukin diftitox.
- Assess the overall survival, time-to-progression, duration of response, and time-to-new therapy in patients treated with this regimen.
Secondary
- Determine whether this regimen depletes or inhibits the function of regulatory T cells in these patients.

结局指标
主要结局
Proportion of Confirmed Tumor Response (Complete Response [CR], Unconfirmed CR, and Partial Response)
时间窗: Up to 5 years
A confirmed tumor response is defined to be either a CR, CRu or PR. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Response criteria for non-Hodgkin's lymphoma (NHL) will be followed. Complete response (CR): (a) Complete disappearance of all detectable disease and disease-related symptoms; (b) All lymph nodes and nodal masses must have regressed to normal size; (c) the spleen must have regressed; CR/unconfirmed (CRu): Those patients who fulfill the criteria in (a) and (c), but with a residual lymph node mass that has regressed by more that 75% in the sum of the products of the greatest diameters (SPD). Partial response (PR): ≥50% decrease in SPD of the six largest dominant nodes or nodal masses; no increase in the size of other nodes, liver, or spleen. Splenic and hepatic nodules must regress by at least 50% in the SPD; No new sites of disease.
