This phase II trial is studying how well giving CCI-779 together with rituximab works in treating patients with relapsed or refractory mantle cell lymphoma. Drugs used in chemotherapy, such as CCI-779, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. 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. Giving CCI-779 together with rituximab may kill more cancer cells

PRIMARY OBJECTIVES:

I. Determine the overall response rate in patients with relapsed or refractory mantle cell lymphoma treated with CCI-779 and rituximab.

II. Determine the tolerability of this regimen in these patients. III. Determine adverse events in patients treated with this regimen.

SECONDARY OBJECTIVES:

I. Determine the time to disease progression and overall survival of patients treated with this regimen.

II. Determine the time to response and duration of response in patients treated with this regimen.

OUTLINE: Patients are stratified according to prior response to rituximab (sensitive [partial response (PR) or complete response (CR) that lasted ≥ 6 months after the last treatment with rituximab alone or in combination with chemotherapy] vs refractory [stable or progressive disease OR a PR or CR that lasted < 6 months after the last treatment with rituximab alone or in combination with chemotherapy]).

Patients receive CCI-779 IV over 30 minutes on days 1, 8, 15, and 22. Patients also receive rituximab IV on days 1, 8, 15, and 22 of course 1 and on day 1 only of courses 3, 5, 7, 9, and 11. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. After completion of course 3, patients undergo reevaluation. Patients achieving a CR or an unconfirmed CR (CRu) receive 2 additional courses of treatment for a total of 5 courses. Patients achieving a PR or stable disease continue study treatment as outlined above for up to 12 courses. Patients achieving a PR or stable disease who subsequently achieve a CR or CRu between courses 3 and 10 receive 2 additional courses of treatment.

After completion of study treatment, patients are followed every 3 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and then annually for 2 years.
