Tests are designed to detect and genotype high-risk HPV types which, if present in persistent infections, can progress to cervical cancer
Roche Diagnostics announced today that the United States (U.S.) Food & Drug Administration has accepted for review its applications for two human papillomavirus (HPV) tests. The Amplicor HPV Test is designed to enable accurate detection of 13 of the more common high-risk HPV genotypes in standard clinical samples. The Linear Array HPV Genotyping Test is designed to identify which of the 13 high-risk HPV genotypes are present in a sample. Persistent infection with HPV is the principal cause of cervical cancer and its precursor, cervical intraepithelial neoplasia.
“DNA tests that are currently used in conjunction with Pap smear tests for cervical cancer screening can only tell if a woman has HPV infection, but cannot identify which type she has,” said Daniel O’Day, head of Roche Molecular Diagnostics, the business area of Roche Diagnostics that developed the test. “We are pleased to be working with the FDA to bring both HPV detection and genotyping tests to the U.S. market. We believe availability of both tests could offer important, clinically relevant information to clinicians working to better identify and manage persistent, high-risk HPV infections before they progress to more serious forms of disease.”
According to the U.S. Centers for Disease Control, genital infection with HPV is the most common sexually transmitted infection in the U.S. today. Over half of sexually active women and men are infected with HPV at some point in their lives. In most cases, infections with HPV are not serious. The majority are asymptomatic, transient, and will resolve without treatment. However, in some individuals, HPV infections result in Pap test abnormalities, and, rarely, cervical cancer.
High-risk HPV types are detected in 99% of cervical cancers and worldwide approximately 70% of cervical cancers are due to HPV types 16 and 18.1 The American Cancer Society estimated that in 2006, over 9,700 women in the U.S. would be diagnosed with, and 3,700 women would die from, cervical cancer.
A recent study, published in the February 28, 2007 issue of the Journal of the American Medical Association2, provided the first national estimate of HPV infection in females aged 14 to 59 years in the U.S. The study, which used the research prototype of the Roche Linear Array HPV Genotyping Test, concluded that the overall prevalence of HPV infection at 26.8% was higher than previous estimates. The highest prevalence of infection was observed in females aged 20 to 24 years, of whom 44.8% were infected. Prevalence of HPV types 16 and 18, which pose the greatest risk for cervical cancer, was much lower at 2.3%.
