Bortezomib, Cladribine, and Rituximab in Treating Patients With Advanced Mantle Cell Lymphoma or Indolent Lymphoma

Phase 2

Completed

Conditions: Indolent Lymphoma
SLL
Lymphoma
Mantle Cell Lymphoma

Interventions: Drug: rituximab
Drug: bortezomib
Drug: cladribine

Registration Number: NCT00980395

Lead Sponsor: University of Arizona

Brief Summary: RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cladribine, 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 bortezomib together with cladribine and rituximab may kill more cancer cells.

PURPOSE: This phase II trial is studying how well giving bortezomib together with cladribine and rituximab works in treating patients with advanced mantle cell lymphoma or indolent lymphoma.

Detailed Description: OBJECTIVES:

Primary

* Determine the 2-year progression-free survival of patients with advanced mantle cell lymphoma or indolent lymphoma treated with bortezomib, cladribine, and rituximab.

Secondary

* Determine the 2-year overall survival of patients treated with this regimen.

* Determine the complete response and overall response rate in patients treated with this regimen.

* Describe the long- and short-term toxicity of this regimen in these patients.

* Determine the prognostic importance of Aurora kinase A in patients treated with this regimen.

* Determine the cytokine profiles for each lymphoma subtype and how they change with this regimen.

* Evaluate the prognostic importance of major carcinogenic pathways using tissue microarray.

OUTLINE: Patients receive bortezomib IV on days 1 and 4, cladribine IV over 2 hours on days 1-5, and rituximab IV on day 1. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Blood samples are collected at baseline and after course 1 for cytokine profile studies. Previously collected tissue samples are obtained for analysis of Aurora kinase A and B, Ki-67, cyclin D, Bcl-2, phosphor-HisH3, c-Met, and VEGF expression by using tissue microarray (IHC staining), reverse transcriptase-PCR, and/or western blotting.

After completion of study therapy, patients are followed up every 3 months for 2 years.

For follicular lymphoma only, at least one prior treatment

Exclusion Criteria

Platelet count of < 100 X10 /L within 14 days before enrollment, unless due to bone marrow infiltration with lymphoma, or due to autoimmune thrombocytopenia because of lymphoma.
Patient has an absolute neutrophil count of < 1.0 X 10/L within 14 days before registration, unless due to bone marrow infiltration with lymphoma.
Patient has a calculated or measured creatinine clearance of <20 mL/minute within 14 days before registration. (Creatinine Clearance is indicated through the Serum Creatinine. If the Serum Creatinine is abnormal, the physician may then due a 24 hour urine to further clarify Creatinine Clearance. A 24 hour urine test is not required per study.)
Patient has ≥ Grade 2 peripheral neuropathy within 14 days before registration.
Myocardial infarction within 6 months prior to registration or has New York Heart Association (NYHA) Class III or IV heart failure. uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities.
Hypersensitivity to bortezomib, boron or mannitol.
Female subject is pregnant or breast-feeding. Confirmation that the subject is not pregnant
Patient received other investigational drugs with 14 days before registration
Serious medical or psychiatric illness likely to interfere with study participation
Diagnosed or treated for another malignancy within 3 years of registration, w/ the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy, or low-risk prostate cancer after curative therapy.
CNS involvement with lymphoma.
Known HIV-positive.
History of disease refractory to a purine analog (defined as remission duration of < 6 months to therapy that included fludarabine, pentostatin, or cladribine).
History of intolerance of bortezomib, boron, mannitol, cladribine, or rituximab.
Patient has > 1.5 X ULN Total Bilirubin
Radiation therapy within 3 weeks before randomization. Enrollment of subjects who require concurrent radiotherapy (which must be localized in its field size) should be deferred until the radiotherapy is completed and 3 weeks have elapsed since the last date of therapy.

Primary Outcome Measures

Name	Time	Method
Progression-free Survival at 2 Years	2 years	PFS was calculated from the first dose of study drug to the first documentation of disease progression, death regardless of cause, or change in therapy due to disease progression, whichever occurred first. If disease progression did not occur by the end of treatment, patients were evaluated every 3 months until progression with physical examination, laboratory studies, and conventional computed tomographic imaging, up to a maximum of 2 years. The Kaplan-Meier product-limit method will be used to estimate progression-free survival in the presence of censoring.
