Alternate Title

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

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase II Prevention Closed 18 to 50 NCI UCIRVINE-02-55 UCIRVINE-2002-2758, NCT00091130

Objectives

1. 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.
2. Compare the natural history of HPV-16 viral load in patients treated with these regimens.
3. Compare the effect of HPV-16 variants on viral load response in patients treated with these regimens.
4. 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.

Entry Criteria

Disease Characteristics:

• Meets criteria for 1 of the following groups:
  • Prospective group, meeting the following criteria:
    • Evidence of atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesions (LSIL) by Pap test
    • Human papillomavirus (HPV)-16-positive by polymerase chain reaction (PCR) and PGMY09/PGMY11 oligonucleotide primers viral load assay
  • Medical records-based group, meeting the following criteria:
    • Medical-record evidence of ASCUS or LSIL by Pap test within the past 6-12 months
    • Meets 1 of the following criteria:
      • Liquid-cytology findings of ASCUS or LSIL
      • Colposcopic evidence of a LSIL by the Reid Index score of 1-5
    • Historically persistent HPV-16-infection by PCR and HPV reverse transcription (RT)-PCR
    • No evidence of high-grade squamous intraepithelial lesions (HSIL) by colposcopy (Reid Index ≥ 6)
    • Reports no sex partner change since last index Pap screening test

• No objects (e.g., tampons, douche, suppositories, fingers, or toes) within the vagina or rectum within 48 hours of virus specimen collection during study visits
• No prior malignancy except nonmelanoma skin cancer
• No medical or psychiatric illness than would preclude study participation or compliance
• No other disorders requiring medical intervention that would preclude study participation

Expected Enrollment

A total of 139 patients (64-70 per treatment arm) will be accrued for this study within 17½ months.

Outcomes

HPV-16 viral load

Natural history of HPV 16 viral load
Effect of HPV 16 variants on viral load response
Regression of cervical atypias (i.e., regression of low-grade squamous intraepithelial lesions atypical squamous cells of undetermined significance) to normal findings

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 as in arm I.

Patients are followed at 12, 24, and 52 weeks after the last vaccination.
