Summary
Abbott Laboratories (ABT) announced on October 13, 2005, that it received a "not-approvable" letter from the U.S. Food and Drug Administration (FDA) regarding its New Drug Application (NDA) for Xinlay™ (atrasentan). This investigational drug was being considered for patients with metastatic hormone-refractory prostate cancer (HRPC). The FDA's decision follows a recommendation against approval by the Oncologic Drugs Advisory Committee (ODAC) in September. While this news represents a setback for the company's prostate cancer drug pipeline, it is important to note that the FDA's decision specifically pertains to the metastatic HRPC indication. Abbott's ongoing trial M00-244, which is evaluating Xinlay™ in patients with non-metastatic HRPC, will not be affected by this particular outcome. Investors should monitor future developments related to the non-metastatic trial and Abbott's overall drug development strategy.
