The 2003 San Antonio Breast Cancer Symposium was a vindication of sorts for an embattled biotechnology company and its controversial founder. The Santa Monica, Calif.-based American Pharmaceutical Partners (APP) presented highly anticipated phase III data for ABI-007, a new paclitaxel formulation, in metastatic breast cancer. Going head-to-head against the standard paclitaxel formulation Taxol, ABI-007 (trade name Abraxane) roughly doubled patient response rates and achieved longer tumor time-to-progression at no cost in toxicity. Company founder and chief executive officer Patrick Soon-Shiong, M.D., expects to apply for U.S. Food and Drug Administration approval for ABI-007 early in 2004.
APPs drug reformulation ambitions go beyond paclitaxel. At the symposium, the company also unveiled a provocative theory to explain why its albumin nanoparticle-based formulation performed so much better than Taxol. The theory, involving a novel transport mechanism that preferentially targets tumors, could have broad implications for delivery of other cancer drugs. APPs theory "is
