Before being a standard therapy, a new anti-cancer drug or combinations should be tested in clinical trials, including phase I, II and III trials and pharmacokinetic study. The phase I trial is aimed to find an optimal dose and pharmacokinetic study is to characterize the drug changed in a body. Besides, genetic background will also affect the efficacy of drugs. Currently, Dr. Shiah studies the correlation of polymorphisms in enzymes, cytochrome P450 and UGT, with the metabolism and effect on CPT-11. Dr. Shiah will initiate a phase I trial to realize the optimal dose and interval of CPT-11 in Taiwanese cancer patients, and to surrogate the specific pharmacogenetic factors. The hepatocellular carcinoma is one of the most important causes of cancer death in Taiwan. Dr. Shiah is interested in the feasibility of some drug combinations for this cancer. For example, some signal transduction pathways are aberrant in the
hepatocellular carcinoma. One of those pathways is through PI 3K/Akt/mTOR. Recently, small molecules aimed to block the function of mTOR have been broadly surveyed. He will use an mTOR inhibitor to treat the patients with hepatocellular carcinoma in a phase I/II trial.


Currently, the parmacogenetic study is ongoing. Dr. Shiah and his colleagues have finished one study, which dealed with the pharmacogenetic and pharmacokinetic studies of CPT-11. The result showed that some metabolic enzymes might be important candidates responsible for the efficacy and complication of CPT-11. It will be validated in future studies.
