JUPITER, Fla., May 10, 2023 (GLOBE NEWSWIRE) -- Dyadic International, Inc. ("Dyadic", "we", "us", "our", or the "Company") (NASDAQ:DYAI), a global biotechnology company focused on building innovative microbial platforms to address the growing demand for global protein production and unmet clinical needs for effective, affordable and accessible biopharmaceutical products and alternative proteins for human and animal health, today announced its financial results for the first quarter of 2023, and highlighted recent company developments.

"Dyadic is off to a great start in 2023, delivering multiple new research collaborations and strong revenue growth of 50.9% year over year," said Mark Emalfarb, President and Chief Executive Officer of Dyadic. "The completion of dosing for our phase 1 clinical trial of DYAI-100 without any serious adverse events has established a safety record with regulatory agencies for proteins produced from our C1 protein production platform. We are also pleased to see our existing partnerships expanded in human and animal health areas, including our licensing agreements with Rubic One Health in Africa and Phibro/Abic animal vaccine program. We are appreciative of BARDA and the FDA's support, we were the only platform technology company to present at the FDA's April 27th Recombinant Protein-Based COVID-19 Vaccines Workshop, along with five other vaccine companies. We believe that our C1 platform is well-position to be an alternative platform in developing next generation vaccines for public health and future pandemics, and we are happy to see C1 is gaining more recognition globally within academia, government, and industry."

"Consistent with our business strategy of focusing on near term commercialization opportunities that can create shareholder value, earlier this week we announced our fully funded co-development and marketing agreement with Fermbox Bio to further leverage our proprietary Dapibus™ platform toward developing and commercializing multiple end-market animal free protein products. Our agreement with Fermbox is singularly focused on commercializing projects for licensing opportunities and will serve to expand our portfolio of recombinant product offerings to address multiple market segments in addition to our internal efforts such as recombinant human and bovine albumin.
