JUPITER, Fla., May 14, 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 first quarter of 2024 and highlighted recent Company progress.

“We continue to execute our business strategy to focus on near-term pharmaceutical and non-pharmaceutical applications for our proprietary and patented C1 and Dapibus™ protein production platforms and pipeline products,” said Mr. Mark Emalfarb, President and CEO of Dyadic. “One of our key highlights was the successful completion of a Phase 1 clinical trial that met its primary endpoint of safety and reactogenicity affirming the safety of proteins produced by Dyadic's C1 platform in humans. We believe this milestone not only establishes the safety of our platform but also provides a solid foundation for C1 technology’s future applications in human and animal vaccines and therapeutics. With the H5N1 ('Bird Flu') virus outbreaks in poultry and U.S. dairy cows, along with one recent human case, we are seeing an increasing interest in our H5N1 'Bird Flu' ferritin nanoparticle human vaccine candidate, developed with ViroVax. Additional animal studies indicate that the vaccine candidate has the potential to generate high neutralizing antibodies for use in cattle. Our Q1 2024 achievements demonstrate our ongoing commitment to enhancing our microbial platforms for diverse applications, and our dedication to improving health for humans and animals, while tackling the challenges of sustainable food production.”

Mr. Emalfarb continued, “As we progress into the second quarter, our Company continues to focus on enhancing the Dapibus™ platform, designed specifically for non- pharmaceutical uses in industries such as food, nutrition, health, and other bioproducts. To accomplish this goal, we have honed our business development strategy, focusing on key areas where our technologies can deliver the greatest impact with shorter commercialization timelines. Our strategy includes simultaneously targeting multiple offtakes for a single product in several corresponding business segments and seeking out new opportunities that are in line with our strategy.”

Joe Hazelton, Dyadic’s Chief Operating Officer, elaborated, “In addition to operational advancements, we also strengthened our financial position with the issuance of $6.0 million in convertible notes, which will be used to accelerate and exploit our strategic objective of near-term revenue generating products and commercialization opportunities for pharmaceutical and non-pharmaceutical applications. We believe that product opportunities such as recombinant human albumin and alpha-lactalbumin provide Dyadic with multiple monetization opportunities as a licensed product or cell line in pharmaceutical, diagnostic, and food applications. We are confident that our strong position, both financially and scientifically, will enable us to implement our business plans with improved capabilities and resources. We are enthusiastic about our future prospects and remain committed to providing value to our customers and stakeholders.”

DYAI-100 Phase 1 Clinical Trial

DYAI-100, a C1-SARS-CoV-2 recombinant protein RBD vaccine candidate, is the first C1-expressed protein tested in humans. The Phase 1 randomized, double-blind, placebo-controlled trial was designed as a first-in-human trial to assess the clinical safety and antibody response of DYAI-100, produced using the C1 platform and administered as a booster vaccine at two single dose levels in healthy volunteers. Following regulatory clearance from the South African Health Products Regulatory Authority (SAHPRA), the trial was initiated in 1Q 2023, with the last patient visit occurring in 3Q 2023. On November 29, 2023, the Company announced the top-line safety results, indicating that the study has met its primary endpoint that both the low and high dose levels of the vaccine are safe and well tolerated among participants. Additionally, the vaccine has been shown to induce immune responses at both dose levels, suggesting its potential efficacy in generating protective immunity against the target virus. The study has been finalized, and the final Clinical Study Report has been issued, demonstrating that the DYAI-100 vaccine met its primary endpoint of safety and reactogenicity.

• In April 2024, Dyadic and its development partner ViroVax reported pre-clinical animal testing on a ferritin nanoparticle H5N1 bird flu recombinant protein human vaccine candidate that demonstrated a strong immune response in rabbits. The potential vaccine combines Dyadic’s C1 single step ferritin nanoparticle H5N1 antigen production with a novel adjuvant from ViroVax. Additional animal studies are being carried out that preliminarily show that this H5N1 bird flu vaccine has the potential to be used in humans.
• Successfully expressed H1N1 influenza antigen in the fully funded research collaboration with the Vaccine and Immunotherapy Center (“VIC”) at Massachusetts General Hospital to express vaccine antigens for influenza A and other infectious diseases, as part of a US $5.88 million award from the Department of Defense (“DoD”).
• On March 25, 2024, the Company entered a funded research collaboration with a top ten pharmaceutical company to develop a vaccine antigen and a monoclonal antibody produced from the C1 technology.
• In March 2024, a manuscript of preclinical studies on C1-produced monoclonal antibody in non-human primates and hamsters was published in the prestigious peer-reviewed journal Nature Communications. A non-human primate challenge study completed dosing of a C1-produced COVID-19 monoclonal antibody (mAb) that had previously demonstrated broad neutralization and protection against Omicron (BA.1 and BA.2) and the other earlier variants of concern in hamsters. Preliminary results obtained from the challenge study with the SARS-CoV-2 Delta virus on non-human primates demonstrated potential high protection. This was the first time a C1-produced monoclonal antibody was used in a non-human primate study validating the safety and efficacy of a C1 produced antibody for infectious diseases.
• On February 28, 2024, the Company’s Dutch subsidiary, Dyadic Nederland BV, entered into a strategic partnership agreement and collaboration with Rabian BV (“Rabian”), a Dutch innovative SME founded by experienced entrepreneurs and vaccine scientists. Awarded by Eurostars for the AVATAR project, a part of the European Partnership on Innovative SMEs (small and medium-sized enterprises), and co-funded by the European Union through Horizon Europe. Rabian will use the total funding of approximately Є1.7 million leveraging its expertise in virology to develop a rabies vaccine using Dyadic’s C1 protein production platform to tackle the challenges posed by rabies, particularly in lower- and middle-income countries. Dyadic is expected to receive an equity stake in Rabian, fully funded research and development costs, and specified product milestones and royalties upon commercialization.
