Furthermore, these medications may not be used during the study if patient is assigned to the rapamycin cohort. * Patients may not be receiving medications that could decrease rapamycin blood concentrations, such as: carbamazepine, phenobarbital, phenytoin, rifapentine, St. John's Wort. Furthermore, these medications may not be used during the study if patient is assigned to the rapamycin cohort. * Patients may not be receiving medications known to cause angioedema with concomitant use of rapamycin, such as angiotensin-converting enzyme (ACE) inhibitors. Furthermore, these medications may not be used during the study if patient is assigned to the rapamycin cohort.
