Clinical Data Presented At American Association for Cancer Research Demonstrate Ability Of TrovaGene, Inc.'s Molecular Diagnostic Platform To Non-Invasively Track Cancer Patients' Response To Therapy

SAN DIEGO, April 8, 2014 /PRNewswire/ -- Clinical study results presented today at the American Association for Cancer Research (AACR) Annual Meeting demonstrate the ability of Trovagene's (NASDAQ: TROV) molecular diagnostic platform to detect and monitor BRAF V600E mutations in cancer patients. The results were presented by Filip Janku, M.D., Ph.D., of The University of Texas MD Anderson Cancer Center.

Of the 33 patients enrolled in the study, Trovagene's BRAF V600E oncogene mutation assay was able to identify the mutation in 29 patients (88%) at any time point during the study, demonstrating a high level of concordance with tissue biopsy. In addition, 25 of the 33 patients (76%) were positively identified for the mutation with their first urine sample. Longitudinal analysis was performed in 17 patients who had more than one urine-based test during the monitoring period. Of these patients, 13 (76%) showed a correlation between response to treatment and mutational status observed by the urine-based test.

"I am encouraged by the study results that show high concordance with standard of care tissue testing and possible utility for monitoring of molecular profile," said Dr. Janku. "This method has potential to allow monitoring of the mutational status in real-time at the individual patient level to determine response or resistance to therapy without a need for relying solely on imaging or repeat biopsies, which have ethical, logistical and financial limitations."

The prospective study enrolled patients whose biopsies had previously tested positive for BRAF V600E mutations by a CLIA-certified laboratory. Of the 33 patients in the study, 32 had diverse advanced cancers and one was diagnosed with Erdheim-Chester disease, a histiocytic disorder often associated with a high prevalence of BRAF mutations. Sequential urine samples were obtained at baseline and over the course of therapy to assess cell-free DNA mutation status. Urinary cell-free DNA analysis was conducted with Trovagene's BRAF V600E oncogene mutation assay using droplet digital PCR.

Mark Erlander, Ph.D., chief scientific officer of Trovagene, added, "The concordance shown between our platform and tissue biopsy in this study are encouraging, especially when we consider that different patients will show response to treatments at different times. Longitudinal monitoring of cell-free DNA in urine allows us to dynamically observe signs of treatment efficacy as well as potential resistance, enabling oncologists to make treatment decisions accordingly."

The poster, titled "Droplet digital PCR detection and longitudinal monitoring of BRAF mutations in cell-free urinary DNA of patients with metastatic cancers or Erdheim-Chester disease," will be displayed at the AACR Annual Meeting until noon PDT on Tuesday, April 8, and subsequently available through Trovagene's website.
