- Researchers are looking for the highest doses of RAD001 and lenalidomide used in combination that can be given safely so small groups of people will be enrolled in steps in this trial. The first group will be given a certain dose of RAD001 and a certain dose of lenalidomide. If they have few or manageable side effects, the next small group of people will be enrolled with a higher dose of RAD001 and/or a higher dose of lenalidomide. This will continue until the highest dose of the drugs used is determined.
