Celecoxib in Treating Patients With Cervical Intraepithelial Neoplasia
Celecoxib in Treating Patients With Cervical Intraepithelial Neoplasia
This randomized phase II trial studies how well celecoxib works in treating patients with
 cervical intraepithelial neoplasia, a precancerous lesion of the cervix which can develop
 into cervical cancer. Celecoxib may be effective in preventing the development of cervical
 cancer in patients who have cervical intraepithelial neoplasia.
PRIMARY OBJECTIVES:

 I. To determine the efficacy of celecoxib to induce complete remission (or partial regression
 to cervical intraepithelial neoplasia (CIN) 1) of CIN 2/3 or CIN 3 as evaluated in the
 post-treatment excisional biopsy.

 II. To determine the toxicity of celecoxib (400 mg once daily) as assessed by Common
 Terminology Criteria for Adverse Events in this patient population of women with CIN 2/3 or
 CIN 3.

 SECONDARY OBJECTIVES:

 I. To assess whether treatment with celecoxib changes the number of quadrants containing
 acetowhite lesions as determined through colposcopic examination.

 II. To determine the efficacy of celecoxib treatment in changing human papillomavirus (HPV)
 viral load in cervical cells.

 III. To examine the association of histologic response; HPV viral load; lesion size;
 proliferation index (marker of proliferation Ki-67 [Ki67]), apoptosis index (terminal
 deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labelin [TUNEL] assay),
 angiogenesis (vascular endothelial growth factor [VEGF]), and cyclooxygenase-2 (COX-2) in
 tissue; the amount of VEGF and basic fibroblast growth factor (bFGF) in serum before and
 after treatment; and the amount of celecoxib present in serum during treatment. Cervical
 cytology karyometry will be assessed as a potential marker for regression IV. To determine
 the feasibility of digital imaging, web-based review of histopathology in a Gynecologic
 Oncology Group (GOG) study.

 V. To compare the diagnoses of the web-based review of histopathology with the diagnoses of
 GOG's standard procedure.

 OUTLINE: 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.
Inclusion Criteria:

 -  Patients must have histologically proven CIN 2/3 or CIN 3 diagnosed by cervical biopsy
 between 2 and 8 weeks prior to enrollment

 -  For a patient to be eligible, the pathology report must clearly state "CIN 2/3"
 or "CIN 3" or must state "moderate-severe dysplasia", "moderate-severe
 dyskaryosis," "severe dysplasia," or "severe dyskaryosis;" patients with a
 diagnosis of CIN 2 alone or moderate dysplasia or dyskaryosis alone are not
 eligible for this study (3/26/2007)

 -  Patients must have a satisfactory (readable, good quality) colposcopic evaluation at
 least 14 days after diagnostic biopsy

 -  Patients must have signed an approved informed consent and authorization permitting
 release of personal health information

 -  Patients must have colposcopically visible cervical lesion at entry consistent with
 biopsy

 -  Patients must have a negative urine pregnancy test; women of childbearing potential
 must practice an acceptable form of contraception (e.g. intrauterine device,
 contraceptive pills, diaphragm, condoms)

 -  Patients must have a GOG Performance Status of 0, 1, or 2

 -  Patients must agree to refrain from using non-steroidal anti-inflammatory drugs
 (NSAIDS) and aspirin during the time they are taking the study medication

 -  Patients must be good candidates for delayed treatment of their CIN, i.e. they must be
 reliable to return for follow-up and provide a combination of at least three phone
 numbers or addresses for contact

 -  Hemoglobin (HgB) greater than 11.0g/dl

 -  White blood cell (WBC) count greater than 3000/mcl

 -  Platelet count greater than 125,000/mcl (3/26/2007)

 -  Creatinine less than or equal to 1.5 x upper limit normal (ULN)

 -  Total bilirubin less than or equal to 1.5 x ULN excluding Gilbert's disease

 -  Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 2.0 x ULN

 Exclusion Criteria:

 -  Patients who are pregnant or lactating

 -  Patients with cytologic or biopsy evidence of endocervical dysplasia or invasive
 cancer

 -  Patients with undiagnosed abnormal vaginal bleeding

 -  Patients who have previously taken celecoxib or any other COX-2 inhibitor at a
 frequency of greater than 3 times per week within 2 months (60 days) prior to
 randomization; patients can use Naproxen without restriction (6/23/2008)

 -  Patients with a known immunocompromised condition

 -  Patients who have had a known allergic reaction to any NSAIDS or aspirin (asthma,
 urticaria, allergic-type reaction)

 -  Patients with a prior history of cervical cancer

 -  Patients with hypersensitivity to Celecoxib

 -  Patients with a known allergic reaction to sulfonamides

 -  Patients with a history of peptic ulcer disease

 -  Patients currently using fluconazole or lithium

 -  Patients with a chronic or acute renal, or hepatic disorder, a significant bleeding
 disorder, or any other condition which in the investigator's opinion might preclude
 study participation for the duration of the trial

 -  Patients with a history of transient ischemic attack (TIA), stroke, cardiovascular
 disease or uncontrolled hypertension
