2. Receipt of 2 or more prior systemic treatments for advanced leiomyosarcoma
3. Active or untreated brain metastases or spinal cord compression
4. Prior treatment with gemcitabine
5. History of major surgery within 4 weeks prior to enrollment
6. Chemotherapy or radiotherapy within 3 weeks prior to the study drug commencement
