About TPI 287

TPI 287 is a proprietary next-generation taxane being studied for the treatment of multiple cancer indications. In preclinical in vitro tests, TPI 287 has exhibited activity across multiple cell lines, including cell lines that either have developed resistance to taxane therapy or are innately resistant to taxane therapy. In addition, in preclinical in vivo animal xenograft models, TPI 287 has exhibited greater tumor growth inhibition activity compared to standard comparative agents in taxane sensitive and taxane resistant tumor cell lines, including cell lines derived from breast and colon cancers and neuroblastoma tumors.

TPI 287 is currently in clinical studies in the United States. Tapestry plans to initiate multiple Phase II trials for TPI 287 in 2007.
