IRX-2 Regimen in Treating Women With Cervical Squamous Intraepithelial Neoplasia 3 or Squamous Vulvar Intraepithelial Neoplasia 3
Study Details
Study Description
Brief Summary
This randomized phase II trial studies how well an IRX-2 Regimen works in treating women with cervical squamous intraepithelial neoplasia 3 or squamous vulvar intraepithelial neoplasia 3. The IRX-2 Regimen consists of a single dose of cyclophosphamide, followed by 21 days of indomethacin, zinc-containing multivitamins, and omeprazole. IRX-2, a human cell-derived biologic with multiple active cytokine components, may act as an immune booster to stimulate the immune system. Giving cyclophosphamide and IRX-2 may work better at treating cervical squamous intraepithelial neoplasia or squamous vulvar intraepithelial neoplasia.

Detailed Description
PRIMARY OBJECTIVES:
- To compare the proportion of subjects who achieve a pathologic complete response (CR) or partial response (PR) in regimen 1 versus regimen 2 at week 25, based on the resected surgical specimen.
SECONDARY OBJECTIVES:
-
To evaluate the toxicity and feasibility of administration of IRX-2 in subjects with confirmed cervical intraepithelial neoplasia (CIN) 3 or vulvar intraepithelial neoplasia (VIN) 3.
-
To evaluate multiple parameters to assess the activity of the IRX-2 regimen for the treatment of CIN 3 or VIN 3: the occurrence of clinical CRs or PRs at weeks 6, 13 and 25.
-
To evaluate multiple parameters to assess the activity of the IRX-2 regimen for the treatment of CIN 3 or VIN 3: frequency of elimination of human papillomavirus (HPV) in cervical or vulvar tissue using a commercial HPV genotyping assay and viral load determination by quantitative polymerase chain reaction (PCR).
-
To evaluate multiple parameters to assess the activity of the IRX-2 regimen for the treatment of CIN 3 or VIN 3: analysis of the immune infiltrates in the resected surgical specimens.
-
To evaluate multiple parameters to assess the activity of the IRX-2 regimen for the treatment of CIN 3 or VIN 3: immunophenotypic analysis of peripheral blood lymphocytes.
-
To evaluate multiple parameters to assess the activity of the IRX-2 regimen for the treatment of CIN 3 or VIN 3: frequency of serum antibodies to HPV E6, E7 and L1 proteins by enzyme-linked immunosorbent assay (ELISA).
-
To evaluate multiple parameters to assess the activity of the IRX-2 regimen for the treatment of CIN 3 or VIN 3: ribonucleic acid (RNA) expression profiling of immune-inflammatory markers from post-treatment resected surgical specimens.
OUTLINE: Patients are randomized to 1 of 2 arms.
Arm I: Patients receive cyclophosphamide intravenously (IV) on day 1 and IRX-2 via submucosal injections in the cervix or subcutaneously (SC) for vulvar lesions on days 4-7. Patients also receive indomethacin orally (PO) three times daily (TID), zinc-containing multivitamins (PO) once daily (QD) and omeprazole orally (PO) on days 1-21.
Arm II: Patients receive cyclophosphamide IV on day 1 and placebo via submucosal injections in the cervix or SC for vulvar lesions on days 4-7. Patients also receive indomethacin PO TID, zinc-containing multivitamins PO QD and omeprazole PO on days 1-21.
In both arms, treatment repeats every 6 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity. Beginning week 25, patients undergo surgical resection.
After completion of study treatment, patients are followed up at 1-8 weeks after surgery.

Outcome Measures
Primary Outcome Measures
- Pathologic response [Week 25]
Complete Response (CR) is defined as absence of intraepithelial neoplasia, Partial Response (PR) is defined as a lower grade of dysplasia than present at baseline (for example, grade 3 decreasing to grade 1).
Secondary Outcome Measures
- Incidence of adverse events of IRX-2 administration [Up to week 25]
Will be assessed by the incidence and severity of adverse events, serious adverse events, as classified and graded according to the current version of the Common Terminology Criteria for Adverse Events version 4.
