Clinical Dilemma In Cancer Treatment Large body of knowledge has been developed around the molecular basis of cancer... Paradigm Shift: Cancers are driven by oncogene mutations... resulting in the trend toward new targeted therapies Effectiveness requires monitoring Resistance develops Therapies are expensive and can have side effects THE CLINICAL UTILITY OF CELL-FREE DNA FROM URINE IMAGING Rough indication of tumor size No molecular information TISSUE BIOPSY Major procedures, not possible in some cases Limitations in access to serial biopsies Tumor heterogeneity; may not obtain the right tissue from the tumor sample CIRCULATING TUMOR CELLS Very low sensitivity Technically challenging, expensive Current monitoring tools are insufficient

Cancer Monitoring Using cfDNA Is An Emerging Trend THE CLINICAL UTILITY OF CELL-FREE DNA FROM URINE “Circulating tumor DNA levels showed a greater dynamic range, and greater correlation with changes in tumor burden, than did CA 15-3 or circulating tumor cells. This proof-of-concept analysis showed that circulating tumor DNA is an informative, inherently specific, and highly sensitive biomarker of metastatic breast cancer”. Sarah-Jane Dawson et. al., Analysis of Circulating Tumor DNA to Monitor Metastatic Breast Cancer, NEJM, Vol. 368, No. 12, March 2013 “Cancer is a disease of DNA. It does make it look as if our means of defining cancer by what tissue it arose in is going to go by the boards pretty soon. Lung, breast, blood—it almost doesn't matter. What matters are the genes that are mutated, the mistakes in the instruction book. For the first time, we have a clear list of targets that are much more smart-bomb opportunities than carpet-bomb opportunities.” Dr. Frances Collins, National Institutes of Health (NIH) Director, ‘Politics on The Frontier of Science’, Wall Street Journal, November 8, 2013

Cell-free DNA Filters Into The Urine THE CLINICAL UTILITY OF CELL-FREE DNA FROM URINE Large volume can be collected High frequency of collection possible Truly non-invasive Patient can self-sample at home or clinic No medical professional required for specimen No refrigeration required No infection risk Lower cost Cell-free DNA stable in urine Urine sample Tracking-cell free DNA Cells in the body die continuously; cancer cells die at an accelerated rate DNA is released into the bloodstream, which is then broken down into smaller segments and filtered by the kidney. Small, stable DNA fragments collect in urine where Trovagene technology can identify and quantify mutations of interest.

Genetic Sequencing Advancements Enable TROV Technology Detecting rare DNA mutation events in urine made commercially feasible by NGS & ddPCR Trovagene IP Next Gen sequencing Digital Droplet PCR TROVAGENE PLATFORM Decline in cost for gene sequencing outpacing Moore’s Law since 2008; reflects transition from Sanger-based to next generation sequencing Source: National Human Genome Research Institute

Trovagene Proprietary Technology Leverages NGS/ddPCR NGS ddPCR TROVAGENE PLATFORM + Resulting in Unparalleled Sensitivity (Analytical Detection to 0.03%) Novel Extraction Process Enrichment of DNA from circulation Enrichment of DNA containing tumor mutations ~100-fold enrichment Because highly degraded need to preferentially pre-amplify ~30bp footprint of DNA having mutation (M) Enriched for Circulating DNA Preferentially isolate short DNA Trovagene IP Portfolio & Know How

Short Sequences in Urine & Novel Primers Solidify IP Position Determining mutational status of short DNAs limits the DNA sequences available for amplification; therefore enabling IP of surrounding DNA that is difficult to navigate around Use of non-human DNA contiguous with primers used to amplify short regions indicates use of non-naturally occurring DNA to interrogate mutations

Shorter DNA footprints leads to increased sensitivity of assays PROPRIETARY ADVANTAGE Interrogating BRAF V600E Mutation DNA sequences available to amplify region are restrictive Single-base Mutation of A→T A G C T A C A G T G A A A T C C T A C A G A G A A A T C T C C T A G C T A C A G T G A A A T C T A G C T A C A G A G A A A T C C T A G C T A C A G T G A A A T 69 ° C C T A G C T A C A G T G A A A T C 71 ° C 20 A T G T C A C T T T A G A G C T A C 68 ° C G A T G T C A C T T T A G A G C T A C 70 ° C (R2) T A G G T G A T T T T G G T C T A G C T A C A G T G A A A T C T C G A T G G A G T G G G T C C A T C C A C T A A A A C C A G A T C G A T G T C A C T T T A G A G C T A C C T C A C C C A G G G A ~ (R2) A A G A T A G SHORTEST SHT FTPT FTPT 35 36.4 13 G T G A T T T T G G T C T C T A C C T C A C C C A G 13 43.1 35 34 32.1 12 T G A T T T T G G T C T C T A C C T C A C C C A 12 40.1 34 35 37.4 14 G T G A T T T T G G T C T A C T A C C T C A C C C 11 35.7 33 34 33.5 13 T G A T T T T G G T C T A G C T A C C T C A C C C A G 14 48.2 35 33 29.0 12 G A T T T T G G T C T A G C T A C C T C A C C C A 13 45.9 34 33 36.9 14 T G A T T T T G G T C T A G G C T A C C T C A C C C 12 42.2 33 32 33.0 13 G A T T T T G G T C T A G A G C T A C C T C A C C C A 14 48.8 34 33 39.2 14 G A T T T T G G T C T A G C A G C T A C C T C A C C C 13 45.5 33 32 36.1 13 A T T T T G G T C T A G C A G C T A C C T C A C C 12 40.4 32 31 33.8 12 T T T T G G T C T A G C G A G C T A C C T C A C C C 14 47.8 33 33 42.1 15 G A T T T T G G T C T A G C T G A G C T A C C T C A C C 13 43.3 32 32 39.4 14 A T T T T G G T C T A G C T G A G C T A C C T C A C 12 38.2 31 31 37.5 13 T T T T G G T C T A G C T A G A G C T A C C T C A C C 14 46.2 32 30 34.9 12 T T T G G T C T A G C T A G A G C T A C C T C A C 13 41.6 31 32 40.1 15 A T T T T G G T C T A G C T A A G A G C T A C C T C A 12 37.9 30 31 38.4 14 T T T T G G T C T A G C T A T A G A G C T A C C T C A C 13 43.2 31 30 36.1 13 T T T G G T C T A G C T A T A G A G C T A C C T C A 14 39.9 30 29 33.3 12 T T G G T C T A G C T A T A G A G C T A C C T C 12 35.8 29 30 39.7 14 T T T G G T C T A G C T A C T T A G A G C T A C C T C A 14 42.0 30 29 37.6 13 LNA1-4 T T G G T C T A G C T A C x x x T T A G A G C T A C C T C 13 38.3 29 28 35.0 12 T G G T C T A G C T A C T T A G A G C T A C C T 12 34.8 28 29 41.3 14 T T G G T C T A G C T A C A T T T A G A G C T A C C T C 14 40.4 29 28 39.2 13 T G G T C T A G C T A C A T T T A G A G C T A C C T vv 13 37.4 28 27 35.0 12 G G T C T A G C T A C A T T T A G A G C T A C C 12 33.6 27 A G C T A C A G T G A A A T C C T A C A G A G A A A T C T C C T A G C T A C A G T G A A A T C T A G C T A C A G A G A A A T C C T A G C T A C A G T G A A A T 69 ° C C T A G C T A C A G T G A A A T C 71 ° C 20 A T G T C A C T T T A G A G C T A C 68 ° C G A T G T C A C T T T A G A G C T A C 70 ° C (R2) T A G G T G A T T T T G G T C T A G C T A C A G T G A A A T C T C G A T G G A G T G G G T C C A T C C A C T A A A A C C A G A T C G A T G T C A C T T T A G A G C T A C C T C A C C C A G G G A ~ (R2) A A G A T A G SHORTEST SHT FTPT FTPT 35 36.4 13 G T G A T T T T G G T C T C T A C C T C A C C C A G 13 43.1 35 34 32.1 12 T G A T T T T G G T C T C T A C C T C A C C C A 12 40.1 34 35 37.4 14 G T G A T T T T G G T C T A C T A C C T C A C C C 11 35.7 33 34 33.5 13 T G A T T T T G G T C T A G C T A C C T C A C C C A G 14 48.2 35 33 29.0 12 G A T T T T G G T C T A G C T A C C T C A C C C A 13 45.9 34 33 36.9 14 T G A T T T T G G T C T A G G C T A C C T C A C C C 12 42.2 33 32 33.0 13 G A T T T T G G T C T A G A G C T A C C T C A C C C A 14 48.8 34 33 39.2 14 G A T T T T G G T C T A G C A G C T A C C T C A C C C 13 45.5 33 32 36.1 13 A T T T T G G T C T A G C A G C T A C C T C A C C 12 40.4 32 31 33.8 12 T T T T G G T C T A G C G A G C T A C C T C A C C C 14 47.8 33 33 42.1 15 G A T T T T G G T C T A G C T G A G C T A C C T C A C C 13 43.3 32 32 39.4 14 A T T T T G G T C T A G C T G A G C T A C C T C A C 12 38.2 31 31 37.5 13 T T T T G G T C T A G C T A G A G C T A C C T C A C C 14 46.2 32 30 34.9 12 T T T G G T C T A G C T A G A G C T A C C T C A C 13 41.6 31 32 40.1 15 A T T T T G G T C T A G C T A A G A G C T A C C T C A 12 37.9 30 31 38.4 14 T T T T G G T C T A G C T A T A G A G C T A C C T C A C 13 43.2 31 30 36.1 13 T T T G G T C T A G C T A T A G A G C T A C C T C A 14 39.9 30 29 33.3 12 T T G G T C T A G C T A T A G A G C T A C C T C 12 35.8 29 30 39.7 14 T T T G G T C T A G C T A C T T A G A G C T A C C T C A 14 42.0 30 29 37.6 13 LNA1-4 T T G G T C T A G C T A C x x x T T A G A G C T A C C T C 13 38.3 29 28 35.0 12 T G G T C T A G C T A C T T A G A G C T A C C T 12 34.8 28 29 41.3 14 T T G G T C T A G C T A C A T T T A G A G C T A C C T C 14 40.4 29 28 39.2 13 T G G T C T A G C T A C A T T T A G A G C T A C C T vv 13 37.4 28 27 35.0 12 G G T C T A G C T A C A T T T A G A G C T A C C 12 33.6 27
