 If you are found to be eligible to take part in this study, you will be assigned to a dose level of BMTP-11 based on when you joined this study. Up to 2 dose levels of BMTP-11 will be tested. Three 3 participants will be enrolled at each dose level. 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 BMTP-11 is found.
