CCI-779 and Rituximab in Treating Patients With Relapsed or Refractory Non-Hodgkin's Lymphoma

Phase 2

Completed

Conditions: Recurrent Mantle Cell Lymphoma

Interventions: Biological: rituximab
Drug: temsirolimus

Registration Number: NCT00109967

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: 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

Detailed Description: 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 by assessing toxicity.

SECONDARY OBJECTIVES:

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

II. Determine the 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.

Arm && Interventions

Group	Intervention	Description
Arm I	rituximab	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.

Primary Outcome Measures

Name	Time	Method
Overall Response Rate (Complete and Partial Responses) as Defined by the International Workshop Criteria	Up to 12, 28-day cycles.	Complete Response (CR) - Complete disappearance of all detectable clinical and radiographic evidence of disease and disappearance of all disease-related symptoms. Partial Response (PR) requires a \>=50% decrease in sum of the products of the greatest dimension (SPD) of the six largest dominant nodes or nodal masses. Overall Response Rate (ORR) - The number of patients who achieve a CR or PR divided by the total number of evaluable patients. We report the Overall Response Rate here.

Secondary Outcome Measures

Name	Time	Method
Time to Progression	Patients were followed up to five years after registration.	Time to progression was defined as the time from registration to the date of progression. Patients who died without disease progression were censored at the date of their last evaluation. Patients who were still receiving treatment at the time of these analyses were censored at the date of their last evaluation. The distribution of this time-to-event end point was estimated using the Kaplan-Meier method.
Duration of Response	Response duration is followed up to 5 years from registration.	Duration of response was defined as the time from the date of documented response to the date of progression. Patients who went off treatment due to other reasons (eg, adverse reactions, refusal of further treatment) were censored at that time. The distribution of this time-to-event end point was estimated using the Kaplan-Meier method.
Toxicity	Assessed during treatment (up to 12, 28-day cycles)	As per the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) Version 3, toxicity was defined as adverse events that are classified as either possibly, probably, or definitely related to study treatment by the treating physician. In this section, we report the number of participants that experienced at least one Grade 3 or higher adverse event.
Overall Survival	Patients were followed for survival status for up to 5 years.	Overall survival (OS) was defined as the time from registration to death resulting from any cause. The distribution of this time-to-event end point was estimated using the Kaplan-Meier method.
