TrovaGene Release: Publication Of Trovera KRAS Liquid Biopsy Test Demonstrates Clinical Utility In Advanced Cancers For Detection And Measurement Of Therapeutic Response

SAN DIEGO, Jan. 24, 2017 /PRNewswire/ -- Trovagene, Inc. (NASDAQ: TROV), a developer of circulating tumor DNA (ctDNA) molecular diagnostics, today announced the publication of study results in Clinical Cancer Research, demonstrating the analytical and clinical performance of Trovera urine and blood liquid biopsy tests to quantitatively assess KRAS mutations in patients with diverse advanced cancers. This data was also featured as a presentation at the 2017 Gastrointestinal Cancers Symposium on January 21^st in San Francisco, CA.

Publication Highlights:

The data demonstrate the clinical utility of Trovagene’s proprietary mutation-enrichment technology to detect and quantitate KRAS mutations in urine and plasma from patients with advanced cancers.

• This was a blinded study with prospectively collected liquid biopsy samples, and archived tissue samples with known KRAS mutation status, from 71 patients with diverse advanced cancers.
• Overall KRAS concordance between ctDNA and tissue specimens was 89% with urine sample volume of 90-110 mL.
• In a subset of patients with simultaneous collection of plasma, data demonstrated excellent concordance of 94% with tumor tissue.
• The dynamics of KRAS^G12/G13 mutant copies of ctDNA from urine and plasma corresponded with patient response to therapy.

“We are continuing to evolve the way diagnostics are used in patients with advanced cancers so that treatment and the potential for improved patient survival is optimized,” said Dr. Mark Erlander, Chief Scientific Officer at Trovagene. “Longitudinal sampling, before, during and after therapy, provides quantitative information about changes in mutational load in patients with advanced cancers. Furthermore, on serial collection, patients with a decrease in ctDNA had a significantly longer time to treatment failure than those who had no change or an increase. The results of this study are important because they add to the growing body of evidence validating the clinical utility of urine ctDNA for detection and quantitation of clinically actionable mutations, as well as monitoring response to therapy in diverse cancer types.”
