ListOutcomeTime frameDescription
PrimaryRestoration of Radioiodine Uptake in Metastatic Lesions as Demonstrated by Diagnostic Whole-body Scanning After Decitabine AdministrationWeek 3 following 2 weeks of Decitabine therapy
Number of participants with restoration of radioiodine responsiveness as determined by visible uptake on radioiodine scan in radiographically detectable metastatic foci of papillary or follicular thyroid carcinoma. Response to Decitabine defined as demonstration of radioiodine uptake determined by centralized blinded review of diagnostic scan. All who demonstrated radioiodine uptake in metastatic foci following decitabine therapy would then undergo thyroid hormone withdrawal and a second course of decitabine in preparation for therapeutic administration of radioiodine. Diagnostic radioiodine scans following decitabine therapy (week 3) with a radioiodine scan following thyrotropin alfa stimulation, 0.9 mg intramuscular (IM) injection 24 and 48 hours before administration of the 131I for imaging. Whole body scans (WBS) performed using a gamma camera.

SecondaryEfficacy of Subsequent Radioiodine Therapy in Terms of CR/PR/SD of Any Radiographic Disease.6 months
Response Evaluation Criteria in Solid Tumors (RECIST): Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD; Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.
Secondary
Change in Fludeoxyglucose (FDG) Uptake Measured by Positron Emission Tomography in Metastatic Tumor Sites Before and After DNA-methyltransferase Inhibitor Therapy (Optional). No Secondary Endpoints Were Measured as no Patient Met the Primary Endpoint.

TypeOutcomeTime framePopulationUnitsMeasured as
PRIMARYRestoration of Radioiodine Uptake in Metastatic Lesions as Demonstrated by Diagnostic Whole-body Scanning After Decitabine AdministrationWeek 3 following 2 weeks of Decitabine therapy
Per protocol, 1 participant interpreted by local treating investigator as responsive (increased radioiodine uptake on diagnostic scan after therapy), entered second decitabine treatment receiving radioiodine therapeutic dose. Subsequent central review of both scans for formal protocol response interpreted scans as negative for radioiodine uptake.
