A "3+3" dose escalation design will be adopted. Patients will start taking LBH589 three times a week and will have a run in period of one week, followed by continous administration of RAD001 from week 2. Pharmacokinetic assessments will be done on day 1 of LBH589 administration and day 1 of concurrent administration of LBH589 + RAD001. ON day 31, there will be a one week drug holiday. This is done to explore the eliminaition kinetics from steady state,as well as the durability of target modulation.
