Dyadic Announces Expanded Licensing Agreement to Develop and Commercialize Vaccines and Biologics for African Continent

JUPITER, Fla., April 12, 2023 (GLOBE NEWSWIRE) -- Dyadic International, Inc. ("Dyadic", "we", "us", "our", or the "Company") (NASDAQ: DYAI), a global biotechnology company focused on building innovative microbial protein production platforms to address the growing demand for global protein bioproduction and unmet clinical needs for effective, affordable and accessible biopharmaceutical products for human and animal health, today announced it signed an expanded licensing agreement for its C1-cell protein expression platform with South Africa’s Rubic One Health (“Rubic”) to develop, manufacture, commercialize and distribute affordable vaccines and biologics for human and animal health in underserved African countries.

  • Prior agreement established co-development basis for researching, developing, and manufacturing multiple other C1 produced COVID-19 vaccines, including DYAI-100
  • Expands license to include vaccines and therapeutic proteins beyond COVID-19 for both human and animal health markets
  • Dyadic will receive certain marketing rights and other consideration, including milestones and royalty payments, from Rubic

“In our initial 2021 agreement with Rubic, Dyadic successfully transferred the C1 platform technology for the discovery, development, manufacturing, and distribution of C1 produced vaccines and biologics, such as monoclonal antibodies. We’ve since progressed to the ongoing Phase 1 first in human trial for the DYAI-100 recombinant RBD booster vaccine candidate for COVID-19, which has facilitated the expansion of our licensing agreement with Rubic. The expanded agreement provides Rubic with the ability to broaden its potential to commercialize both human and animal health products for Africa using our C1 technology. Our collaborators continue to observe the advantages of the C1 protein production platform, which include accelerated development timelines, improved productivity, and lower manufacturing costs,” stated Mark Emalfarb, Dyadic’s CEO.

“Rubic’s mission is to develop a solution for the discovery, development, evaluation and manufacture of high-quality, cost-effective, human and animal vaccines and therapeutic proteins, for distribution primarily in the African markets,” said Dr. Julian Naidoo, CEO of Rubic One Health.

“It is imperative that African nations acquire and commercialize technology and manufacturing capabilities necessary to deploy preventative and therapeutic treatments for broad populations, both affordably and timely. Expanding our partnership with Dyadic affords Rubic increased capabilities to rapidly develop, manufacture and distribute a broader portfolio of high-quality human and animal health vaccines and biologic drugs, without the need for extreme temperature control requirements, more efficiently, in less time, and at an affordable cost. This agreement will help Rubic achieve its strategic goal of providing an end-to-end solution for vaccine and drug development, production, and distribution, for the African continent,” concluded Dr. Julian Naidoo.
