Conditions cervical cancer, cervical intraepithelial neoplasia grade 2, cervical intraepithelial neoplasia grade 3
Treatments hydrocortisone/placebo, celecoxib
Phase phase 2
Sponsor Gynecologic Oncology Group
Collaborator National Cancer Institute (NCI)
Start date June 2005
End date January 2100
Trial size 130 participants
Trial identifier NCT00081263, CDR0000360805, GOG-0207, NCI-2009-00583, U10CA101165


This randomized phase II trial is studying how well celecoxib works in preventing cervical cancer in patients with CIN. Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer or to treat early cancer. Celecoxib may be effective in preventing the development of cervical cancer in patients who have cervical intraepithelial neoplasia (CIN).

Additional Information

Principal investigator Janet Rader
Description PRIMARY OBJECTIVES: I. Determine the efficacy of celecoxib, in terms of achieving histologic complete or partial response, in patients with cervical intraepithelial neoplasia (CIN) 2/3 or 3. II. Determine the toxicity of this drug in these patients. SECONDARY OBJECTIVES: I. Determine the effect of this drug on changes in lesion size in these patients. II. Determine the effect of this drug on human papillomavirus (HPV) viral load in these patients. III. Correlate histologic response, HPV viral load, lesion size, proliferation index, apoptosis index, angiogenesis (VEGF) and COX-2 in tissue, amount of VEGF and bFGF in serum, and serum celecoxib levels during treatment in these patients. OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to lesion size (covering ≤ ½ area of the cervix vs covering > ½ area of the cervix) and degree of cervical intraepithelial neoplasia (CIN) (CIN 2/3 vs CIN 3). Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive oral celecoxib once daily for 14-18 weeks. ARM II: Patients receive oral placebo once daily for 14-18 weeks. Patients undergo colposcopy at week 8 and between weeks 14 and 18. Between weeks 14 and 18, patients with evidence of disease also undergo large loop excision of the transformation zone (cone biopsy) or cervical biopsy and patients with no evidence of disease undergo a cervical biopsy to confirm the absence of disease on colposcopy.
