Study Groups: Dose Escalation: If you are found to be eligible to take part in this study, you will be assigned to a dose level of the combination of pazopanib and everolimus based on when you joined this study. Up to 8 dose levels of pazopanib and everolimus will be tested. Up to 6 participants will be enrolled at each dose level. The first group of participants will receive the lowest dose level. Each new group will receive a higher dose than the group before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of pazopanib and everolimus is found. Expansion: Once the highest tolerable dose of pazopanib and everolimus is found, up to 14 more participants may be enrolled to further study the safety of the drugs at that dose and the efficacy of the drugs in a certain tumor group. Study Drug Administration: Each study cycle is 28 days. Pazopanib and everolimus are taken by mouth on an empty stomach (1 hour before meals or 2 hours after meals).

Everolimus will be taken every odd day (7, 9, 11, and so on). Beginning with Cycle 2, you will take pazopanib every even day (2, 4, 6, and on so) and everolimus every odd day (3, 5, 7, and so on). Study Visits: At each study visit, you will be asked what about any drugs or herbal supplements that you may be taking and if you have had any side effects.

If you are able to become pregnant, you will have a blood (about ½ teaspoon) or urine pregnancy test. PK testing: At least 6 participants in the expansion part of the study will have blood (about 1 teaspoon each time) will be drawn for pharmacokinetic (PK) testing. The study staff will tell you if you will have this testing. PK testing measures the amount of study drug in the body at different time points. On Day 5 of Cycle 1 and Days 1 and 2 of Cycle 2, blood will be drawn before and 8 more times up to 10 hours after taking the study drugs. On Day 2 of Cycle 2, blood will be drawn 1 more time for PK testing after 24 hours of taking everolimus. If you could not have the 10 hour draw the day before, this will be drawn at this day. On Day 6 of Cycle 1 and Day 3 of Cycle 2, blood will be drawn 1 time for PK testing after 24 hours of taking pazopanib. If you could not have the 10 hour draw the day before, this will be drawn at this day. Blood will be drawn 1 time at the end-of-dosing visit. Length of Study: You may continue taking the study drugs for as long as you are benefitting. You will be taken off study early if the disease gets worse, intolerable side effects occur, you develop new health problems, or your doctor thinks that it is no longer in your best interest to receive the study drug.

Pazopanib is FDA approved and commercially available for the treatment of advanced renal cancer and certain types of advanced soft tissue sarcoma but has not been approved for use in other cancer types. Everolimus is FDA approved and commercially available for the prevention of kidney transplant rejection, to treat advanced renal cancer, and to treat subependymal giant cell astrocytoma associated with tuberous sclerosis. The combination of pazopanib and everolimus to treat advanced cancer is investigational. Up to 62 patients will be enrolled in this study. All will be enrolled at MD Anderson.
