Post-Approval Studies (PAS) Database

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.

Final Safety Findings No severe adverse events were reported
Final Effect Findings A negative HPV result predicted a lower 3-year risk of ¡ÝCIN3 than did a negative cytology result.

The low 3-year (cumulative incidence ratio) CIR for a negative HPV result also confirmed the safety of a

3-year interval for HPV primary screening. The follow-up study confirmed the continued high risk of

HPV16 or HPV18 infection, with the observation that 1 in 4 women who tested HPV 16+ at Baseline and

1 in 9 who tested HPV18+ at Baseline were diagnosed with ¡ÝCIN3 within 3 years.

The follow-up data for the NILM population ¡Ý30 years demostrated safety over 3 years

of a negative HPV test at Baseline in the context of adjunct testing. In addition, the data demonstrated a higher risk associated with HPV16+ or HPV18+ results (9.56%).

Study Strengths & Weaknesses Strengths: Large sample size, high compliance at all follow up years, compliance with exit colposcopy

was 88%.

Weaknesses: Comparisons of cumulative Incidence rate (CIRs) of high-grade cervical disease between subjects with a positive and those with a negative Cobas HPV tests is only limited to up to 3 years.
Recommendations for Labeling Changes Labeling incorporating the long term Post approval study were submitted and approved
