If you are found to be eligible to take part in this study, the amount of study drug you receive will be based on when you join the study. Three (3) to 6 participants will be enrolled in this study and given a certain dose. If they do not experience intolerable side effects, the next 3-6 participants enrolled will receive a higher dose. This process will continue until researchers find the highest dose of the drug that can be given without causing serious or intolerable side effects. The study doctor will tell you what dose you will be receiving and how this compares to the doses other participants have received.
