Brief Summary

This trial is designed to assess the tolerability and efficacy of simvastatin plus FOLFIRI (irinotecan, 5-FU, leucovorin) in metastatic colorectal cancer patients.

Detailed Description

Progress in treatment for metastatic CRC has undoubtedly been achieved in the past decade. Until 1985, 5-fluorouracil (5-FU) was the only agent available for the treatment of metastatic CRC. Several trials have attempted to enhance the activity of bolus 5-FU, by the addition of levamisole or interferon. Despite of these attempts, no survival advantage was established until the introduction of the newer cytotoxic drugs. The addition of folinic acid (FA) to 5-FU, the use of infusional rather than bolus 5-FU, and the combination of new active agents such as irinotecan and oxaliplatin with 5-FU/FA have resulted in an increase in activity of 5-FU. In trials of current combination regimens as first-line therapy, response rates exceeding 30% and median survival duration longer than 16 months have been reported. In all, despite of rapid advances in the treatment of metastatic CRC during the last decade, the efficacy of treatment still needs to be improved. One potential way of increasing the survival of metastatic CRC patients is the introduction of a novel targeting agent to the standard cytotoxic regimen such as IFL (irinotecan, fluorouracil, and leucovorin). An increasingly recognized molecular target for anticancer treatment is the rate-limiting enzyme of the mevalonate pathway, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase. The end products of the mevalonate pathway are required for a number of essential cellular functions such as sterols for membrane integrity, ubiquinone for cell respiration, geranylgeranyl isoprenoids for covalent bindings to the ras family, dolichol for glycoprotein synthesis, and isopentenyladenine for tRNA function and protein synthesis. Fortunately, inhibitors of the key enzyme, the statins, are well established and have been used safely in the clinic for the treatment of hypercholesterolemia for decades. Therefore, HMG-CoA reductase may be a decent molecular target for anti-cancer therapy and statins may be readily applicable to the clinic once its potential role as an anticancer drug is established. The statins have recently gained attractions from medical oncologists because large retrospective analyses for efficacy trials of statins in coronary artery disease have shown that not only are these agents able to reduce cardiac disease-related mortality, but cancer incidence is also reduced by 28 - 33 %.

In all, further clinical trials investigating on combining the standard treatment with these novel molecular targeting agents, the statins, are definitely warranted.
