The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Study Status Completed
Application Number P080015 / PAS001
Date Current Protocol Accepted 03/12/2009
Study Name Cervista HPV HR Assay
General Study Protocol Parameters
Study Design Prospective Cohort Study
Data Source New Data Collection
Comparison Group Concurrent Control
Analysis Type Analytical
Study Population Transit. Adolescent B (as adults) : 18-21 yrs, Adult: >21
Detailed Study Protocol Parameters
Study Design Description The study is a prospective, cohort study. The study consists of women that are 30 years or older with a normal pap test and Cervista HPV test at baseline. The enrolled subjects come back for their routine screening visits on an annual basis and have a Pap test at each follow-up visit.
Study Population Description Study Population: Women 30 years or older who have a NILM cytology result at baseline. Indication: The Cervista HPV 16/18 test can be used adjunctively with the Cervista HPV HR test in combination with cervical cytology to screen to assess the presence or absence of high-risk HPV types 16 and 18 in women 30 years and older.
Sample Size 2000 patients, 26 sites
Data Collection Safety endpoints do not apply. The effectiveness endpoints include cervical cytology, colposcopy/biopsy, and HPV 16/18 test.
Follow-up Visits and Length of Follow-up The study required 3 years of follow-up. Follow-up inculdes annual visits.
Interim or Final Data Summary
Interim Safety Information Saftey information not applicable
Actual Number of Patients Enrolled 2026
Actual Number of Sites Enrolled 26
Patient Follow-up Rate 3 years
Final Safety Findings The estimates for Cervista HPV 16/18 positive over Cervista 16/18 negative relative cumulative risk at the end of 3 years is 0.015 as compared to 0.009 (p=0.630).

Sensitivity = 20.0% (95% CI: 3.6 ¨C 62.4) Specificity = 95.1% (95% CI: 93.8 ¨C 96.1)

Positive predictive value = 1.4% (95% CI: 0.0 ¨C 5.0) Negative predictive value = 99.6% (95% CI: 99.6-99.9)

Final Effect Findings Please see safety findings.
Study Strengths & Weaknesses The cumulative 3 year incidence for Cervista HPV 16/18 test is based on one HPV positive with CIN2+ were compared to two HPV negative with CIN2+. Thus, it is unclear if data from the PAS supports that Cervista HPV 16/18 test (P80015) is more effective in triaging women to colposcopy.

Another weakness is the generalizability of the study as

the absolute 3 year cumulative risk of developing ¡ÝCIN2 in Cervista HPV HR [1.1% (4/362)] positive women is lower in the Cervista NILM ¡Ý30 population in comparison to cross-sectional and longitudinal data using other approved assays.

Recommendations for Labeling Changes The study results for the three year follow-up of women with NILM ¡Ý30 with normal cytology

and the uncertainty surrounding the conclusions will be included in the label Study limitations).
