OraSure's Colli-Pee® First-Void Urine Collection and Preservation Device and nRichDX Revolution Sample Prep System for cfDNA Extraction

IRVINE, Calif., March 27, 2023 /PRNewswire/ -- nRichDX and OraSure Technologies, Inc., have advanced a commercial collaboration to validate and co-promote their products for researchers developing liquid biopsy applications using first-void urine samples. Notably, first-void urine is enriched in biomarkers suitable for molecular analysis in applications such as sexually-transmitted infections, human papillomavirus, and early-stage cancer.

Orasure's Novosanis Colli-Pee® First-Void Urine Collection Device with UAS™ Preservative and the nRichDX Revolution Sample Prep System™ for extraction of analytes, like cfDNA and cfRNA, from up to 20 mL of urine in a single extraction.

The companies' products are highly complementary. The innovative, patented Colli-Pee® sample collection and preservation device, made by OraSure's subsidiary Novosanis, is designed to hygienically collect a consistent, volumetric first-void urine sample, and preserve the cell-free nucleic acid (cfDNA, including circulating cell-free tumor DNA, and cfRNA) with its proprietary UAS™ reagent. nRichDX's patented Revolution Sample Prep System™ is the only IVD-labeled, cfDNA sample prep system that can process up to 20 mL of urine in a single extraction.

Together, the Colli-Pee first-void urine collection device with UAS preservative, combined with the nRichDx Revolution System, a semi-automated cfDNA extraction platform, offers a seamless and efficient workflow for large-scale studies requiring urine sample collection, preservation, handling and extraction for downstream processing.

"nRichDX is pleased to collaborate with OraSure to provide researchers and clinicians solutions to deliver the highest yields of highly pure cfDNA and ctDNA from urine," said William Curtis, CEO of nRichDX. "Liquid biopsy test developers are looking forward to the creation of highly sensitive assays from non-invasive urine samples. The unique Revolution System, together with the innovative Colli-Pee® device, delivers unmatched yields of cfDNA and ctDNA from urine" he said.

"First-void urine collection is convenient for patients and provides important insight into the state of their health," said Kathleen Weber, Chief Product Officer for OraSure. "We are excited about this collaboration, which utilizes the Colli-Pee® device for first-void urine collection and preservation of important biomarkers that can be extracted with the nRichDx Revolution System. We look forward to the possibilities that higher DNA yields can enable as researchers look for ways to use first-void urine as a more accessible, non-invasive liquid biopsy sample type to expand the potential for global screening, detection, and monitoring of cancers and other medical conditions."

The companies have jointly presented data for cfDNA and ctDNA yields from first-void urine at last November's Association for Molecular Pathology (AMP) Meeting, as well as co-developing an Application Note and have plans to present at upcoming industry conferences and in future publications.

About nRichDX:

nRichDX® is an emerging leader in sample prep solutions for the isolation of cfDNA, ctDNA, RNA and other rare analytes. The patented Revolution Sample Prep System™ was engineered specifically for liquid biopsy applications. It is the first and only high-yield, high-recovery, IVD-labeled sample prep platform that can process from 1 mL - 20 mL of plasma or urine sample volumes in a single extraction using the company's unique nRicher Cartridge™. Unlike other methods, Revolution sample prep doesn't require yield-lowering sample pooling, bead recycling, or sample transfer steps. nRichDX helps solve one of precision medicine's greatest problems – – inaccurate or incomplete diagnostic results for liquid biopsy-based applications due to insufficient analyte.
