Summary
Brief summary (as posted)
Thioredoxin reductase plays an critical role in lung cancer patients, in vitro study showed that, ethaselen, specific inhibitor of thioredoxin reductase, could inhibit lung cancer cell growth and induce apoptosis. In China, phase 1 clinical trials of ethaselen showed that 1200 mg dose ethaselen could be well tolerated, in pre-clinical study we found that, approximately 50% non-small cell lung cancers harbored high thioredoxin reductase expression(IHC result ++ or +++), phase 1a/b of ethaselen had finished in 2008, the result showed that 1200mg ethaselen per day was safety and tolerated by Chinese malignant tumor patients.In pre-clinical research, our group found that, elevated of thioredoxin reductase activity was associated with the expression of thioredoxin reductase tested by immunohistochemistry, which means high expression of this enzyme may be a favourite predicted factor of ethaselen, the specific inhibitor of thioredoxin reductase.

- patients pathologic diagnosis advanced non-small cell lung cancer who had received more than two lines standard treatment, according to NCCN Non-small cell lung cancer guideline, there were no standard treatment scheme for these patients. Approximately 40 patients will be included in the study, patients will received oral ethaselen dispersible tablet, 600 mg bid dose, patients may quit the study whenever they would like or investigator evaluate that progression disease has developed, or any grade of SAE developed during the study.
