Measure
No Intervention, Then Pioglitazone
After enrollment, subjects will be observed for 24 weeks for skin cancer tumors. Tumors will be appropriately treated as per standard of care. Then they will begin the pioglitazone regimen for 24 more weeks, during which time skin cancer tumors will be observed and appropriately treated as per standard of care. There was no washout period. Pioglitazone: 15 mg of pioglitazone orally for 2 weeks, and if well tolerated, 30 mg pioglitazone orally for 5 1/2 months.
Pioglitazone, Then no Intervention
Subjects will begin the 24 week pioglitazone regimen immediately after enrollment, during which time skin cancer tumors will be observed and appropriately treated as per standard of care. After 24 weeks of drug, subjects will be observed for 24 weeks for skin cancer tumors. Tumors will be appropriately treated as per standard of care. There was no washout period. Pioglitazone: 15 mg of pioglitazone orally for 2 weeks, and if well tolerated, 30 mg pioglitazone orally for 5 1/2 months.
