Estimated Enrollment: 90
Study Start Date: May 2009
Estimated Study Completion Date: May 2011
Estimated Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Genexol-PM

All the patients are recurrent breast cancer after taxane treatment. Patients with a measurable lesion (at least 1 measurable lesion)

  1. Spiral CT : lesion ≥ 10mm (unidimension)
  2. X-ray, MRI, ultrasound : lesion ≥ 20 mm (unidimension)
Drug: Paclitaxel loaded Polymeric micelle
Genexol-PM at a dose of 300mg/m2 was diluted in 500 ml of 5% dextrose solution or normal saline and infused i.v. for 3 h on day 1.Treatment was repeated every 3 weeks until either disease progression or intolerance. A minimum of 6 cycles was recommended.
Other Name: Genexol-PM®

Detailed Description:
Genexol-PM is a novel Cremophor EL-free polymeric micelle formulation of paclitaxel. This single arm, multicenter phase IV study was designed to evaluate the response rate, toxicity, progression free survival and tumor control rate of Genexol-PM in patients with Taxane-pretreated recurrence breast cancer.
