If you are found to be eligible to take part in this study, you will be assigned to a dose level of nab-paclitaxel based on when you joined this study. Up to 4 dose levels of nab-paclitaxel will be tested. The first group of participants will receive the lowest dose level. Each new group will receive a higher dose than the group before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of nab-paclitaxel is found.
