 ABI-007 brand name AbraxaneTM is a form of the chemotherapy drug called paclitaxel. Standard paclitaxel is formulated with ethanol and a substance called Cremophor EL polyoxyethylated castor oil. However, these additives are felt to contribute to the side effects possibly severe associated with paclitaxel. ABI-007 does not contain these additives and may deliver more drug to tumor cells. ABI-007 is approved by the United States Food and Drug Administration FDA in the treatment of metastatic advanced breast cancer, and is being evaluated in other cancers in research studies.
