SAN DIEGO, Oct. 1, 2013 /PRNewswire/ --Trovagene, Inc. (NASDAQ: TROV), a
developer of cell-free molecular diagnostics, today announced availability of
the first urine test for cancer mutation monitoring through the company's CLIA
laboratory. The robustness of Trovagene's ultra-sensitive assay procedure has
been demonstrated for detection of the BRAF V600E mutation from cell-free DNA
in urine. This mutation commonly occurs in melanoma, as well as several other
prevalent cancer types.

Of the more than 70,000 cases of melanoma diagnosed each year in the United
States, up to 70 percent harbor a BRAF-type mutation and of these, 80 percent
may be positive specifically for BRAF V600E.^1 There are several FDA-approved
targeted therapies for the treatment of BRAF-positive melanoma, making
mutational status monitoring an area of clinical interest among treating
physicians.

Trovagene's cell-free BRAF^SM test is a laboratory-developed test (LDT)
designed to detect and monitor this mutation in metastatic cancer patients
with biopsy-proven V600E BRAF mutation in their tumor. It is the first
commercial assay within Trovagene's cancer monitoring portfolio performed
using a droplet digital PCR (ddPCR) platform. Using urine as a non-invasive,
systemic sample, the cell-free BRAF test could help physicians monitor changes
in mutation status for patients requiring therapy for cancers that have this
mutation. For patients with difficult-to-biopsy metastatic tumors, urine-based
mutation testing may also provide a viable alternative to check mutation
status as part of the initial treatment workup.

"We are developing a systemic, non-invasive cancer monitoring system," said
Mark Erlander, Ph.D., chief scientific officer for Trovagene. "Traditionally,
the mutation status of a tumor is determined using a tissue sample – a method
that has limited practicality for patient monitoring due to costs, tumor
heterogeneity and potential complications from the biopsy process. The ability
to detect the mutation signal in cell-free DNA isolated from urine overcomes
this limitation and meets a significant technical and clinical need."

The cell-free BRAF mutation assay has been tested across a range of solid
tumors including melanoma, non-small cell lung, rectal, and colon cancers,
indicating that urine-based mutation detection is applicable across many
cancer types. Additional clinical studies are ongoing to further understand
the full range of clinical applications for this and other Trovagene assays.

"This first assay represents a significant milestone for Trovagene," said
Antonius Schuh, Ph.D., chief executive officer of Trovagene. "Moving forward,
our goal is to apply our technology for improved monitoring of tumor dynamics,
leading to more effective management of cancer patients."

Trovagene has detected the BRAF V600E mutation in a variety of cancers, with
high levels of sensitivity and strong concordance with tissue biopsy. Further
expansion of the company's monitoring capabilities will include additional
mutational markers with known clinical utility, as well as known genomic
alterations that indicate resistance to therapy.

The Trovagene cell-free BRAF test is now available to healthcare providers for
patient testing. Physicians interested in utilizing this test should contact
