Primary Outcome Measures:
  • Time to clearance of high-risk human papillomavirus infection. [ Time Frame: At each visit ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of subjects with evidence of regression to normal cytology. [ Time Frame: Screening Visit and Follow-up Visits (Months 6, 8, 14, 20, and 26). ] [ Designated as safety issue: No ]
  • Proportion of subjects with improvement in cervical lesions as rated by the investigator (measured by colposcopy). [ Time Frame: At each visit ] [ Designated as safety issue: No ]
  • Proportion of subjects who develop histological evidence of cervical intraepithelial neoplasia. [ Time Frame: Visits 1-3 as assigned by group ] [ Designated as safety issue: No ]
  • Time to progression of disease to precancer. [ Time Frame: Visits 1-3 as assigned by group ] [ Designated as safety issue: No ]
  • Change in relative light units ratios relative to the positive control from Hybrid Capture 2® assay (semi-quantitatively assessing viral load). [ Time Frame: At each visit ] [ Designated as safety issue: No ]

Detailed Description:

Cervical cancer is caused by infection with specific genotypes of the human papillomavirus referred to as oncogenic or high-risk human papillomavirus. Current epidemiologic evidence suggests that 80% of sexually active women will become infected during their lifetime with human papillomavirus and 50% of these infections will be due to high-risk human papillomavirus. With US annual rates of cervical cancer now in the range of 13,000/year, a very substantial number of women are left with uncertainty regarding whether their infection will clear spontaneously or progress to cancer.

Subjects participating in this study were required to visit the clinic for approximately 15 or 16 visits, and maintain a diary of self-dosing and menstruation cycles. The total time of participation in this study was approximately 27 months.
