Additional Information

TPI 287, a proprietary next-generation taxane, is Tapestry's lead clinical compound. This compound was designed to overcome multiple drug resistance in solid tumors that are innately resistant to taxane therapy or have become resistant to taxanes following exposure to chemotherapy drugs. In preclinical testing, TPI 287 demonstrated the ability to inhibit tumor cell growth in a number of in vitro cell lines and has shown inhibition of human tumor growth in certain animal xenograft models when tested against standard comparative agents. The in vitro activity was seen across multiple cell lines including cell lines known to be sensitive to taxanes as well as cell lines known to be resistant to taxanes. Taxane sensitive cell lines in which TPI 287 has shown activity include cell lines derived from breast cancer, uterine cancer and non-small cell lung cancer. Taxane resistant cell lines in which TPI 287 has shown activity include cell lines derived from breast cancer, colon cancer and prostate cancer. See
