Azacitidine to Restore Thyroid Function in Patients With Persistent or Metastatic Thyroid Cancer

• Status: Completed
• Trial end date: 2006-08-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Azacitidine may help thyroid cancer cells regain the ability to take up iodine. This would allow the cancer to be detected and treated by radioactive iodine.

PURPOSE: Phase I trial to study the effectiveness of azacitidine to restore thyroid function in treating patients who have persistent or metastatic thyroid cancer.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Lucille P. Markey Cancer Center at University of Kentucky
• Collaborator: National Cancer Institute (NCI)
• Treatments: Azacitidine

Criteria

DISEASE CHARACTERISTICS: Radiologically confirmed persistent or metastatic follicular or papillary thyroid cancer following total thyroidectomy and radioiodine ablation therapy Metastatic disease confirmed histologically or cytologically or by elevated thyroglobulin levels No radioiodine uptake by whole body scanning Stable iodine contamination from radiologic contrast material within the past 10 months allowed, if absence of current contamination demonstrated by less than 80 micrograms of iodine in a 24 hour urine collection

PATIENT CHARACTERISTICS: Age: Any age Performance status: Not specified Life expectancy:

Not specified Hematopoietic: Absolute neutrophil count at least 1,500/mm3 Platelet count at least 100,000/mm3 Hepatic: SGOT/SGPT no greater than 2.5 times upper limit of normal (ULN) Bilirubin no greater than 1.5 times ULN Renal: Creatinine no greater than 1.5 times ULN OR Creatinine clearance at least 50 mL/min Other: Not pregnant or nursing Negative pregnancy test Fertile patients must use effective contraception

PRIOR CONCURRENT THERAPY: At least 4 weeks since prior levothyroxine Any prior therapy for restoration of radioiodine uptake allowed, if unsuccessful and did not exceed treatment schedules planned for this study
