First Urine-Based Molecular Diagnostic Test for Transrenal Cancer Mutation Monitoring

29 Nov 2012

Product news

Trovagene, Inc. has announced successful development of its first molecular diagnostic test capable of detecting KRAS mutations from a urine specimen. Transfer of the transrenal KRAS test to the company’s CLIA lab is expected to be completed in December 2012 with commercial availability expected in January 2013.

“Our scientific team has developed the first commercially viable process for quantitative detection of KRAS mutations in transrenal DNA isolated from a simple urine specimen,” said Charlie Rodi, Ph.D., chief technology officer of Trovagene. “This represents a breakthrough in cancer monitoring, and will provide oncologists and surgeons with the ability to frequently check mutation status before, during, and after therapy.”

Cell-free nucleic acids originate from both normal and diseased cells, circulate through the bloodstream, cross the kidney barrier, and can be detected in urine as transrenal DNA. As interest in this technology grows among leading academic cancer centers, Trovagene continues to engage with new collaborators to develop a series of transrenal molecular diagnostic tests to detect and monitor cancer mutations. Trovagene's initial oncogene mutation tests will include KRAS, BRAF and PIK3CA. Potential uses of this non-invasive technology include monitoring for recurrence of disease, determining response to therapy and disease detection.

Solid tumors represent more than 90% of all cancers, and approximately 24% of these are KRAS mutation positive. Based on current cancer incidence rates in the US, each year an estimated 360,000 newly diagnosed patients are expected to have KRAS mutation-positive cancers.

“Over the next six months, we plan to introduce a variety of assays that may offer significant clinical benefits for physicians and patients, as well as potential savings for the healthcare system,” stated Antonius Schuh, Ph.D., chief executive officer of Trovagene. “The ability to test, detect and confirm cancer mutation status non-invasively represents an enabling technology that can be used across a variety of clinical applications.”

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors.

The number of wells microplates contain can range from 6 to 3243 wells, with the 96-well format being the most commonly used. Microplates can come tailored for a range of applications including cell culture, PCR, filtration, storage, non-binding surface, protein crystallization, as well as pre-coated, deep well and normal Standard microplates. Additionally, options for microplate colors include clear , black, white or black with clear bottom and white with clear bottom for absorbance microplate reader applications.

Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Clinical GeneticsMolecular Genetics covers the analysis of hereditary genetic disease and chromosomal abnormalities. Genetics can be analysed using DNA, RNA, and protein microarrays, PCR, RT PCR and DNA sequencing. Genetic equipment includes genetic workstations, thermal cyclers, cooling blocks and electrophoresis products. Diagnostic kits are used for DNA / RNA extraction and purification.Cancer DiagnosticsThere are a wide variety of diagnostic tests for cancer available, and this range continues to expand as our knowledge of cancer improves. Current diagnostic methods include biopsy, imaging and blood tests for known biomarkers. New methods in research development include liquid biopsies and cancer breathalyzers.UrineThe analysis of urine is important in medicinal, anti-doping, forensic and life sciences applications. The ability to evaluate what someone has ingested through their urine enables fast detection and diagnosis of certain illnesses. Cancer ResearchAlthough cancer is often referred to as a single condition, it actually consists of more than 100 different diseases. Microscopy, mass spectrometry, high throughput sequencing and flow cytometry are some of the most common techniques employed in cancer research labs.BRAFKRASBRAFPIK3CA
