JUPITER, FL / November 10, 2021, Dyadic International, Inc. (“Dyadic”, “we”, “us”, “our”, or the “Company”) (NASDAQ: DYAI), a global biotechnology company focused on further improving, applying, and deploying its proprietary C1-cell protein production platform to accelerate development, lower production costs and improve the performance of biologic vaccines and therapeutics today announced its financial results for the third quarter of 2021, and highlighted recent Company progress. 

Mark Emalfarb, Dyadic’s President and Chief Executive Officer, said, “We continue to make progress in our efforts to enhance and advance our C1 protein production platform. A successful Phase 1 human clinical trial of our DYAI-100 COVID-19 vaccine candidate would help us accelerate the adoption of our C1 platform, moving us closer to realizing C1’s commercial potential in the pharmaceutical market in 2022 and in the years ahead. We expect to demonstrate the C1 platform’s safety in humans in the near term and are now diligently working towards the completion of a CMC/cGMP manufacture process. We expect DYAI-100 to move into first-in-human clinical trials in 2022 — independently and/or potentially through our global network of development partners. Dyadic’s mission since the DuPont transaction has been to transform life sciences manufacturing processes and deliver a cost-effective production platform that increases biomanufacturing outputs while satisfying the growing demand for protein production and unmet needs, affordably, across biologic drugs, vaccines and other protein based biologic products and processes.” 

Mr. Emalfarb continued “The C1 platform is proving to be a ubiquitous platform which is currently being validated and adopted for use globally in middle and low-income countries as well as in major markets. We believe in the potential of DYAI-100, which serves as the first example of one of the potentially dozens, if not hundreds of more affordable protein-based products, including vaccines, at flexible commercial scales. The current DYAI-100 clinical program is expected to enable two key strategic advancements for Dyadic, first to demonstrate that our proprietary and patented C1-cell line can be grown under cGMP conditions, producing proteins which are safe for use in humans as well as to serve as a proof of concept for the development and manufacture of high volumes of low cost, next generation mono and multivalent recombinant protein vaccines for COVID-19 and other diseases affecting humans and animals.” 

“We are delighted to announce a new addition to our executive leadership team as Joe Hazelton joins Dyadic as Chief Business Officer. As Dyadic’s corporate and operational profile continues to mature, we continue to invest in human capital to explore the expanding pipeline of new business opportunities more fully.” concluded Mr. Emalfarb.

About Dyadic International, Inc.

Dyadic International, Inc. is a global biotechnology company which is developing what it believes will be a potentially significant biopharmaceutical gene expression platform based on the fungus Thermothelomyces heterothallica (formerly Myceliophthora thermophila), named C1. The C1 microorganism, which enables the development and large-scale manufacture of low-cost proteins, has the potential to be further developed into a safe and efficient expression system that may help speed up the development, lower production costs and improve the performance of biologic vaccines and drugs at flexible commercial scales. Dyadic is using the C1 technology and other technologies to conduct research, development and commercial activities for the development and manufacturing of human and animal vaccines and drugs, such as virus like particles (VLPs) and antigens, monoclonal antibodies, Fab antibody fragments, Fc-Fusion proteins, biosimilars and/or biobetters, and other therapeutic proteins. Certain other research activities are ongoing which include the exploration of using C1 to develop and produce certain metabolites and other biologic products. Dyadic pursues research and development collaborations, licensing arrangements and other commercial opportunities with its partners and collaborators to leverage the value and benefits of these technologies in development and manufacture of biopharmaceuticals. As the aging population grows in developed and undeveloped countries, Dyadic believes the C1 technology may help bring biologic vaccines, drugs, and other biologic products to market faster, in greater volumes, at lower cost, and with new properties to drug developers and manufacturers, and improve access and cost to patients and the healthcare system, but most importantly save lives.
