25This is an approach which can inflict significant toxicity. An alternative is to block expression of oncogenes which are over-expressed only in cancer cells, a therapeutic approach which could reduce toxicity to the host while maximizing destruction of the oncogene-dependent malignant cells.
Atorvastatin has been shown to decrease levels of active oncogenes in preclinical studies with murine and human lymphoma cell lines, and administration of statins leads to shrinkage of lymphoma in murine models. Therefore, it may be possible for atorvastatin to decrease levels of active oncogenes in human lymphomas. Further, upon decrease in levels of active oncogenes, human lymphomas may regress. Atorvastatin is a commonly prescribed drug for hypercholesterolemia: targeting the 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase enzyme may also be a way to decrease activation of oncogenes in human lymphoma, with minimal toxicity. For human low grade non-Hodgkin lymphoma, no curative treatment is available; therefore new, non-toxic and targeted therapies are sought for this disease.
80 mg orally once daily
Atorvastatin, 80 mg tablet, will be taken orally by the patient daily, beginning on study day 1.

Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Women of child-bearing potential must have negative BetaHCG at enrollment Exclusion Criteria: Chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study Not recovered from adverse events due to agents administered more than four weeks earlier Has stable low grade lymphoma has had rituximab within 3 months Patient with relapsed or refractory disease has had rituximab within 1 month Not recovered from adverse events due to surgery performed 4 weeks earlier Receiving any other investigational agent. Known brain metastases Taken any statin within the past 6 months prior to enrollment in the trial Currently abuses alcohol Currently takes cyclosporin or gemfibrozil Patient has a prior history of rhabdomyolysis Has uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. Pregnant: Patients are not excluded if they are breastfeeding at the time of enrollment, but breastfeeding should be discontinued if the mother is treated with atorvastatin.

Expressed as the number of participants whose tumor cells showed an increase in apoptosis during atorvastatin treatment
The validity of tumor apoptosis as a biologic endpoint was assessed by correlation to clinical response. A correlation substantially less than 1 is interpreted as a poor correlation, while a correlation near +1 or -1 is interpreted as a strong correlation.
Assessed as the number of study participants with atorvastatin-related serious adverse events (SAEs).
