Final Results of First Independent Study Highlight Clinical Effectiveness of Cervista HPV HR Test
Wednesday, July 07, 2010
Cervista® HPV HR demonstrates equal sensitivity and increased specificity compared to Hybrid Capture 2
BEDFORD, Mass., July 7 /PRNewswire-FirstCall/ -- Hologic, Inc. (Hologic or the Company) (Nasdaq: HOLX), a leading women's healthcare company, today announced that final data analysis from the first large-scale independent evaluation of clinical performance of Cervista® HPV HR compared to Hybrid Capture 2 (hc2), were presented in Montreal, Canada, at the 26th International Papillomavirus Conference. Cervista HPV HR is a diagnostic test for the detection of 14 high-risk human papillomavirus (HPV) types.
The study, SHENCCAST II, is a major cervical cancer screening trial conducted in China to evaluate the performance of HPV assays, among other endpoints. The final analysis of this arm of the study, which included 8,435 patients, showed sensitivity for the identification of confirmed CIN2 or greater was statistically equivalent for the Cervista HPV HR test (92.9%) and hc2 (95.6%). However, Cervista HPV HR demonstrated a statistically significant improvement in specificity compared to hc2 (91.1% vs 88.6%; p = <.05). Overall HPV positivity in the study population was 11.1 percent for the Cervista HPV HR test and 13.6 percent with the hc2 test. Cervista HPV HR also had a significantly lower HPV positivity rate (6%) for patients with normal cytology compared to hc2 (7.9%).
While the Cervista HPV HR test demonstrated improved specificity and similar sensitivity, a statistical analysis of overall test accuracy that plots sensitivity and specificity found the two methods were clinically equivalent (area under the ROC curves).
"We had presented preliminary results from our trial at AOGIN in March. These data further validate the efficacy of the Cervista HPV HR test for identifying patients at risk of developing or harboring cervical neoplasia," said Jerome Belinson, M.D., Professor of Surgery, Section of Gynecologic Oncology at the Cleveland Clinic and President of Preventive Oncology International. "Our analysis clearly showed that both of these methods performed well and with similar overall accuracy."
"The conclusions of this study should not be under estimated. This is the first head-to-head clinical study to date comparing clinical performance of Cervista HPV HR and Hybrid-Capture 2," said Edward Evantash, M.D., Medical Director and Vice President of Medical Affairs at Hologic. "These clinical data, in combination with its specific advantages in HPV testing, further demonstrate the additional value Cervista HPV brings to overall patient care."
About the Hologic Cervista® HPV Tests
The Cervista HPV HR and Cervista HPV 16/18 diagnostic tests are based on Invader® chemistry, a patented technology owned by Hologic and well established in other areas of molecular testing. Both tests are approved for use utilizing the sample collected with the ThinPrep® Pap Test, offering additional convenience for the healthcare provider.
Approved by the U.S. Food and Drug (FDA) Administration in March 2009, Cervista is the first new HPV assay in over a decade. It is the only FDA-approved test to feature an internal control, which allows confidence that a negative result is not the result of an insufficient sample. In addition, Cervista requires a sample size that is half that of the older competitor's test, which should result in fewer patient call backs. The assay also reduces lab processing time while providing some additional workflow advantages.
The Cervista HPV HR test screens for 14 of the most common disease-causing strains of HPV. The Cervista 16/18 test is the only HPV test available to diagnose for strains 16 and 18, which account for more than 70 percent of all cervical cancers.
About Human Papillomavirus and Cervical Cancer
HPV is the most common sexually-transmitted disease (STD) in the United States and is recognized as the cause of most cervical cancers. To help prevent the onset of disease, the American College of Obstetrics and Gynecology (ACOG) suggests routine Pap and HPV testing for women over the age of 30 to identify women most likely to develop cervical cancer.
