SGN-00101 Vaccine in Treating Human Papillomavirus in Patients Who Have Abnormal Cervical Cells

Descrizione dettagliata
PRIMARY OBJECTIVES:
I. Compare the effectiveness of SGN-00101 vaccine vs placebo in reducing the human papillomavirus (HPV)-16 viral load in patients with atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesions (LSIL) of the cervix with persistent HPV-16 infection who are at increased risk for developing a high-grade squamous intraepithelial lesion or invasive cervical cancer.
II. Compare the natural history of HPV-16 viral load in patients treated with these regimens.
III. Compare the effect of HPV-16 variants on viral load response in patients treated with these regimens.
IV. Compare the relative effectiveness of these regimens on the regression of cervical cellular atypias (based on Pap test results), in terms of the regression of cytologic findings of LSIL and ASCUS to normal findings and resolution or regression of colposcopically defined cervicovaginal lesions, in these patients.
OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive SGN-00101 vaccine subcutaneously (SC) on day 1 of weeks 1, 4, and 8 for a maximum of 3 injections in the absence of unacceptable toxicity or the development of an invasive malignancy or serious illness.
ARM II: Patients receive placebo vaccine SC on day 1 of weeks 1, 4, and 8 for a maximum of 3 injections in the absence of unacceptable toxicity or the development of an invasive malignancy or serious illness.
Patients are followed at 12, 24, and 52 weeks after the last vaccination.

Following the univariate modeling, multivariate logistic regression models will be constructed by adding the demographic factors, baseline viral load, and type of cellular atypia to the model.
The univariate logistic regression model for infection resolution is equivalent to a chi-square test.
