Celecoxib in Treating Patients With Progressive Metastatic Differentiated Thyroid Cancer
RATIONALE: Celecoxib may stop the growth of thyroid cancer by stopping blood flow to the tumor and by blocking the enzymes necessary for tumor cell growth.
PURPOSE: Phase II trial to study the effectiveness of celecoxib in treating patients who have progressive metastatic differentiated thyroid cancer.

|Official Title:||Phase II Study Of Celecoxib In Metastatic Differentiated Thyroid Carcinoma|
- Examine efficacy of celecoxib in patients with progressive metastatic differentiated thyroid carcinoma by assessing progression free survival. [ Time Frame: up to 12 months following treatment ] [ Designated as safety issue: Yes ]
- Quantifying gene expression and protein levels of angiogenic markers[vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and tumor necrosis factor (TNF)-α] in peripheral blood mononuclear cells (PBMCs) from pre-,during- [ Time Frame: pre-study, every eight weeks and off study ] [ Designated as safety issue: No ]
- Quantifying gene expression and protein levels of cytokines [interleukin (IL)-10, IL-12, IL-6 and interferon (IFN)-γ] in peripheral blood mononuclear cells from pre-,during-, and post-treatment blood samples. [ Designated as safety issue: No ]
- Evaluate cyclooxygenase (COX)-2 protein expression by immunohistochemistry in tumor biopsies to correlate with clinical response. [ Designated as safety issue: No ]
|Study Start Date:||January 2003|
|Study Completion Date:||June 2006|
|Primary Completion Date:||June 2006 (Final data collection date for primary outcome measure)|
- Determine the efficacy of celecoxib, in terms of progression-free survival, in patients with progressive metastatic differentiated thyroid carcinoma.
- Correlate cyclooxygenase (COX)-2 protein expression in tumor biopsies by immunohistochemistry with clinical response in patients treated with this drug.
OUTLINE: Patients receive oral celecoxib twice daily beginning on day 1. Treatment continues for 1 year in the absence of disease progression or unacceptable toxicity. Patients who achieve a complete response (CR) receive 3 additional months of therapy beyond documentation of CR.
Patients are followed at 4-8 weeks.
PROJECTED ACCRUAL: A total of 35 patients will be accrued for this study within approximately 6 months.
