The anticancer agent paclitaxel (marketed as Taxol) has shown remarkable activity against metastatic breast cancer. However, the Taxol formulation requires prolonged administration times, and there are safety problems that have been attributed to the solvent rather than the active ingredient, paclitaxel. This is a new formulation of paclitaxel that has been found to have fewer safety problems than Taxol, and may be administered safely at higher doses. This study will investigate the safety and efficacy of this new formulation of paclitaxel given intravenously once a week for three weeks, followed by a rest week. This cycle will be repeated until safety problems or treatment failure require that the patient stop therapy.

Study summary:

The anticancer agent paclitaxel (Taxol for Injection Concentrate, Bristol-Meyers Squibb) has a broad spectrum of activity against several human cancers including carcinomas of ovary, breast, lung, esophagus and head and neck cancer. Taxol has shown remarkable activity against metastatic breast cancer, yielding response rates in the range of 40% to 60% in chemotherapy-naive patients and 25%-30% in patients refractory to anthracycline-containing regimens (Taxol package insert). The major limitation of Taxol is its poor water soluability requiring Cremophor (containing castor oil and ethanol) as a solvent. Taxol in this vehicle must be administered over 3-24 hours, and hypersensitivity reactions to Cremophor require a premedication routine of a corticosteroid, an antihistamine, and an H2 antagonist. In this study, the test medication (ABI-007) is a nanoparticle colloidal composition of protein-stabilized paclitaxel that is reconstituted in saline. The infusion time for ABI-007 is minimal compared to Taxol (under an hour), and there is no premedication required. The maximally tolerated dose of this formulation of paclitaxel is 300 mg/m2, as compared to 175 mg/m2 for Taxol. As tumor response has been shown to be dose-dependent for paclitaxel, a higher dose allows for a potentially better response. This open-label, Phase II study will determine the safety, tolerability and anti-tumor effect of ABI-007 monotherapy administered weekly in patients with metastatic breast cancer that have been previously treated with Taxol.
