– Bio-Rad expects to make equity investment in support of deal – Agreement provides for global exclusivity in transplant monitoring commercialization – Bio-Rad granted subsequent investment option upon FDA clearance IRVINE, Calif., April 11, 2024 (GLOBE NEWSWIRE) — Oncocyte Corporation (Nasdaq: OCX), a precision diagnostics company, today announced a partnership agreement with Bio-Rad Laboratories (NYSE: BIO), a global leader in life science research and clinical diagnostics products, for the commercialization of its research use only GraftAssure™ assay, powered by Droplet Digital™ PCR (ddPCR™)*. The new product is expected to launch in Q2 2024 to a select group of academic transplant centers in the US and EU and more broadly in the second half of the year. As part of the agreement, Bio-Rad and Oncocyte will co-market the assay inside the US and Germany, with Oncocyte acting as commercial lead. Outside these countries Bio-Rad has been granted exclusive global distribution and commercial rights. “As we move towards launch, having the support of the Bio-Rad team in the US and Germany gives us the scale we need to meet the market opportunity,” said Josh Riggs, Oncocyte’s CEO. “The QX600 ddPCR platform, along with their expertise in serving the life science market, makes Bio-Rad a natural partner for our transplant technology.” Going forward, both companies have committed to joint efforts in developing a regulated product designed to facilitate widespread distribution and clinical adoption in the United States and beyond. Additionally, Bio-Rad has been granted an option for IVD commercial rights at FDA clearance, subject to meeting specific objectives. Exercising the option would come with a second equity investment into Oncocyte. Further details of the agreement can be found in Oncocyte’s filing with the Securities and Exchange Commission. dd-cfDNA is a proven, non-invasive biomarker with growing demand offering an estimated three million testing opportunities globally and driving a market exceeding $1 billion.
