This is a non-randomized, multicenter, open label, single agent phase II study. Patients with malignant mesothelioma that has recurred or progressed following chemotherapy, and who qualify for this study, will receive milataxel 60 mg/m2 orally on Day 1 of a 21 day cycle. If no toxicities of greater than Grade 1 severity occur, patients will receive 75 mg/m2 for the second and subsequent cycles. Patients will receive drug for a total of six cycles. Milataxel administration in excess of six cycles will be permitted at the discretion of the Investigator if patients have stable or responding disease.
