JUPITER, FL / August 13, 2024 (GLOBE NEWSWIRE) Dyadic International, Inc. (“Dyadic”, “we”, “us”, “our”, or the “Company”) (NASDAQ: DYAI), a biotechnology company focused on the efficient large-scale manufacture of proteins for use in human and animal vaccines and therapeutics, as well as non-pharmaceutical applications including food, nutrition, and wellness, today announced its financial results for the second quarter of 2024 and highlighted recent Company progress.

"This quarter, we saw the positive impact of our business strategy, which focuses on near-term non-pharmaceutical applications and mid- to long-term applications in animal and human health for our proprietary and patented C1 and Dapibus™ microbial protein production platforms and pipeline products,” said Mark Emalfarb, President and CEO of Dyadic.

Joe Hazelton, Dyadic’s Chief Operating Officer, commented, "As previously outlined, we have refined our business development strategy to concentrate on areas where we believe our technologies can achieve commercialization more quickly. Our recent development and commercialization agreement with Proliant Health and Biologicals exemplifies how we are monetizing our platform technologies. By focusing on product opportunities like recombinant human albumin and alpha-lactalbumin, both of which have significant global partners, Dyadic has gained multiple avenues for monetization as a licensed product or cell line in pharmaceutical, diagnostic, food, nutrition, health and wellness applications. We are excited about our prospects and remain dedicated to delivering value to our customers and stakeholders.”

Recently, the Company commissioned an independent vaccine expert to assess our adjuvanted avian influenza (“Bird Flu”) ferritin nanoparticle human vaccine candidate, developed in collaboration with ViroVax, LLC.  The expert assessment provided a positive outlook on the initial animal studies, reporting that:

“Following a two-dose regimen of ViroVax NP-H5N1 RVPs a significant median neutralizing antibody titer ~11,000 and near identical cross-neutralization titers, ~9,000, of three RVP clades (e.g. A/Vietnam/1203/2004 and A/Astrakhan/3212/2020) were induced in rabbits. These are robust functional antibody responses that are induced following one dose and indicative of a booster immune response.” 

This assessment indicates the potential of our adjuvanted avian influenza (“Bird Flu”) ferritin nanoparticle human vaccine candidate to generate high neutralizing antibodies for use in humans, and potentially in poultry, cattle and other animals. As the Bird Flu continues to spread globally among wild birds, poultry, and U.S. dairy cows, and a few recent cases in humans we are experiencing a growing interest in our C1 produced Self-assembling Nanoparticle H5-2.3.4.4b A/Astrakhan antigen.

Mr. Emalfarb continued, “As we move into the third quarter, our company remains focused on enhancing the Dapibus™ platform, which is designed specifically for non-pharmaceutical uses in industries such as food, nutrition, health and wellness, and other bioproducts. Our strategy involves targeting multiple offtakes for a single product in various business segments while seeking new opportunities that align with our goals. Our achievements in the second quarter highlight our ongoing commitment to advancing our microbial platforms for a broad range of protein applications in the alternative proteins sector as well as in animal and human health.”

Recent Company Progress

Alternative Proteins

Non-Food Applications

● On June 28, 2024, the Company announced that it entered into a development and commercialization partnership with Proliant Health and Biologicals (“PHB”), a leading supplier of purified proteins for the diagnostic, nutrition and cell culture markets. According to the terms of the agreement, Dyadic received an initial payment of $500,000 in July 2024. Dyadic will receive a second payment of $500,000 upon the completion of the transfer of a Production Strain (as defined in the agreement), and will receive a final payment of $500,000 upon the meeting of a certain productivity threshold. Dyadic will also receive a share of profits received by PHB from the sale of animal-free recombinant albumin products produced using Dyadic’s filamentous fungal microbial platforms. A portion of the upfront milestone payment will be allocated to the technology transfer and commercialization effort. The initial focus of the partnership will be the commercialization of recombinant human serum albumin products, with the anticipated launch of the first product in the first half of 2025.

● The Company has completed its development of the DNASE-1, and a Certificate of Analysis has been issued for the product, which is expected to begin sampling in the third quarter.

● The Company’s project to produce recombinant transferrin for use in cell culture media for the alternative protein industry has achieved high titers with additional optimization and analysis ongoing; product samples are expected to be available in the fourth quarter.

● The Company’s recombinant bovine albumin was shown in third party application testing to be comparable to animal derived bovine albumin for use as a component of cell culture media to grow animal muscle cells for the cultured meat industry; further development and analyses are ongoing.

Food Applications

● As previously announced, in September 2023, the Company entered into a development and exclusive license agreement to commercialize certain non-animal dairy enzymes used in the production of food products using Dapibus™ and received an upfront payment of $0.6 million in October 2023. The Company believes it has achieved the specified target yield level required for achieving a milestone payment and is in the process of delivering the strain for verification by its partner. The development of a second enzyme is progressing.

● The Company has developed a highly productive strain and is actively sampling recombinant alpha-lactalbumin, a whey protein, and has entered into a joint development agreement with a Top 10 global dairy company for the development of food grade alpha-lactalbumin. Additionally, the Company has ongoing discussions with plans to provide samples to three additional alternative protein companies.

● The Company is sampling recombinant lactoferrin for several interested parties.

Bio Industrial Products

● Dyadic has developed three enzymes, with plans for two additional enzymes, that have the potential for use in multiple industries, such as dairy, nutrition, biogas, biofuels and biorefining. Several initial enzymes are under evaluation with interested parties.

Animal Health

● The Company continued its ongoing development and collaboration with Phibro Animal Health/Abic Biological Laboratories Ltd to develop vaccines and treatments for livestock animal diseases.

● The Company has provided samples of the C1 produced H5 A/Astrakhan 2.3.4.4b recombinant ferritin nanoparticle antigen to multiple parties for evaluation and potential use in poultry and cattle vaccines.

● Initial studies indicate that the adjuvanted C1 produced H5 A/2.3.3.4.b A/Astrakhan ferritin nanoparticle antigen has the potential for use as an animal vaccine candidate against the current avian influenza ‘Bird Flu’ viruses in poultry and cattle.  

● Animal studies conducted by ViroVax has demonstrated that the C1 produced H5 A/Astrakhan 2.3.4.4b ferritin nanoparticle vaccine elicits high neutralizing antibodies against the three circulating viruses: (a) H5/Influenza A/Astrakhan/3212/2020, (b) H5/Influenza A /Texas/37/2024, and (c) H5/Influenza A/Dairy Cattle/Texas/24-008749-003/2024.

Human Health

● In April 2024, Dyadic and its development partner ViroVax reported pre-clinical animal testing on an adjuvanted H5 Clade 2.3.3.4.b A/Astrakhan avian influenza ferritin nanoparticle ‘Bird Flu’ human vaccine candidate that demonstrated a strong immune response in rabbits. The potential vaccine combines Dyadic’s C1 single step ferritin nanoparticle antigen production with a novel antigen and adjuvant from ViroVax. In the second quarter, the Company presented an overview of a H5N1 ‘Bird Flu’ recombinant protein human vaccine candidate to BARDA Tech Watch, NIH, and to the White House Office of Pandemic Preparedness and Response Policy.

● The Company successfully delivered a C1 produced H1N1 influenza antigen in a fully funded research collaboration with the Vaccine and Immunotherapy Center at Massachusetts General Hospital. The program is focused on expressing vaccine antigens for influenza A and other infectious diseases, as part of a US $5.88 million award granted to Massachusetts General Hospital from the Department of Defense.

● In third party funded programs, the C1 Platform has:

o successfully expressed multiple infectious disease antigens including HPV, HIV, and multiple RSV antigens;

o delivered three mAbs for evaluation as neutralizing antibodies for infectious diseases; and 

o two additional mAbs in development, including a top ten pharmaceutical company.
