"Issuance of this patent further strengthens Trovagene's extensive patent portfolio supporting our Precision Cancer Monitoring platform," said Bill Welch, chief executive officer of Trovagene.
Trovagene is submitting a manuscript this quarter that provides data validating the sensitivity and specificity of its HR-HPV, high-risk human papillomavirus urine test in comparison with the Roche Cobas HPV test. "The data in this manuscript will show that urine sampling is a viable testing alternative, particularly to access women who do not participate in routine screening programs," said Mark Erlander, chief scientific officer of Trovagene
Complementing the recently submitted manuscript, and adding to the body of clinical evidence supporting the sensitivity and specificity of Trovagene's HR-HPV urine-based test, two abstracts have been accepted for presentation at the HPV 2017 31st International Papillomavirus Conference. The first demonstrates clinical performance of urine and cervical samples in a Chinese screening population. These results support the utility of urine testing for cervical cancer screening among this population. The second abstract describes the analytical performance of the Trovagene HPV-HR urine test
