- Patients can have received no more than two prior chemotherapy regimens for metastatic disease. Patients may be currently receiving paclitaxel using one of the schedules in the protocol, as long as the treating investigator has reasonable expectation that the patient will continue to receive paclitaxel for 2 or more additional cycles. The current regimen does not count towards the 2 regimens as long as the patient is not progressing on therapy.
