Measure
Pioglitazone Treatment
If eligible, subjects can participate in 1 or both parts of this study as follows: Part 1: In the initial main portion of the study subjects will receive 24 -28 weeks of therapy with pioglitazone at the dosage approved for the control of diabetes. Response will be evaluated per RECIST. Safety measure are outlined in the protocol including weekly weigh ins, calls, labs, exams, etc. Part 2: A secondary protocol is then available to subjects who complete the main initial study with less than complete response per RECIST. They can undergo a radioiodine scan to see if the treatment with pioglitazone has sensitized their disease to radioiodine. If it has - they can pursue the radioiodine treatment. Pioglitazone

SECONDARY outcome

Timeframe: Baseline and 24 weeks

Determine if pioglitazone decreases serum thyroglobulin in patients with follicular-patterned thyroid carcinomas that contain the PAX8-PPARgamma fusion gene.

SECONDARY outcome

Timeframe: 24 weeks

Toxicities experienced by patients with PAX8-PPARgamma fusion gene-positive follicular-patterned thyroid carcinomas treated with pioglitazone are indicated by presence of Serious Adverse Events (that show relatedness).

0 serious adverse events

OTHER_PRE_SPECIFIED outcome

Timeframe: 24 weeks

Define predictive markers of response or insensitivity to pioglitazone. Unstained tumor tissue slides from archival paraffin blocks, fresh biopsy specimens from measurable metastases, and blood samples (serum and peripheral blood cells) will be collected on enrolled patients who consented for the optional correlative studies. These will be used to identify factors that predict efficacy of pioglitazone. Analyses may include measures of expression of specific RNAs and proteins, and DNA sequence analysis.

Outcome measures

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: 24 weeks

Determine if pioglitazone induces a clinically significant level of radioiodine uptake in the residual thyroid carcinoma, and if so, whether there is a therapeutic response to radioiodine. This will be addressed in a separate follow-up protocol available to subjects completing this study.

OTHER_PRE_SPECIFIED outcome

Timeframe: 24 weeks

Determine (by MRI) if pioglitazone induces lipid accumulation in follicular-patterned thyroid carcinomas that contain the PAX8-PPARgamma fusion gene.
