Once it is decided which drugs you will receive, you will be enrolled into a group of about 3-6 participants that are receiving the same drug combination. The first group of participants will receive the lowest dose of the drug combination. The next group of participants will receive the next highest dose of the drug combination. The third group will receive an even higher dose than that. This process will continue until the study doctor finds the highest safe dose of the drug combination. The dose that you receive will depend on when you are enrolled in this study and the safety data that is available at that time. The dose that you receive may be lowered if you do not tolerate the study drug combination well.
