Thirty-eight US Oncology, Inc. affiliated medical centers nationwide continue to play a significant role in the clinical research of Abraxane that was approved today by the U.S. Food and Drug Administration (FDA). Abraxane (paclitaxel protein-bound particles for injectable suspension), a next generation taxane, and the first in a new class of albumin-bound nanotechnology, was approved for the treatment of metastatic breast cancer.
US Oncology conducted a phase 2 clinical trial of Abraxane in patients with metastatic breast cancer who were resistant to taxane drugs and continue to participate in the ongoing clinical development of the drug. Clinical trials of Abraxane have shown that the new drug is superior to solvent-based paclitaxel (commonly marketed as Taxol) in response rate and time to tumor progression.
