The drug originally belonged to a company called Tanox, set up in the US by researcher Chang Tse-wen of the Academia Sinica's Genomics Research Center and his then wife Nancy Chang, also a leading biotech researcher. The company had spent seven or eight years from the lab to the second phase of clinical trials, and success was in sight.
此一藥物原屬中研院基因體研究中心研究員張子文與前妻唐南珊在美國創立的 Tanox 公司所有，該公司從實驗室到臨床第二期，已投入七、八年時間，眼看成功在望。
