JUPITER, Fla., Aug. 10, 2022 (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 and affordable biopharmaceutical products for human and animal health, today announced its financial results for the second quarter of 2022, and highlighted recent company developments.

"The recent submission of our first-in-human clinical trial application with the South African Health Products Regulatory Authority (SAHPRA) is a significant milestone for Dyadic and our C1-cell protein production platform," said Mark Emalfarb, President and Chief Executive Officer of Dyadic. "We have leveraged our industrially-proven C1 platform to bring a rapid, highly productive, and affordable approach for emerging and developed countries to fight against COVID-19, and we believe that our novel C1 protein production platform could be instrumental in the control and prevention of infectious and other diseases. It is important to note that in addition to assessing the DYAI-100 vaccine candidate for safety and preliminary efficacy against the SARS-CoV-2 virus, this will be the first time that a protein produced by Dyadic's proprietary and patented C1 protein production platform will be used in a human clinical trial. The anticipated first in human safety data is expected to provide the regulatory support for and accelerate the adoption of the C1 platform to develop and produce vaccines and therapeutics in addition to our DYAI-100 vaccine candidate. This is an important step toward establishing C1 as a transformative option as a protein production platform for biopharmaceuticals. C1 has been our core platform for speeding the development and manufacture of human and animal pharmaceutical products and will continue to serve as our foundation in the life sciences arena."

Mr. Emalfarb continued, "The Company now has commercial agreements in each of its three core verticals: Human Health, Animal Health, and Alternative Proteins. With the anticipated first-in-human data for a C1-produced product expected later this year, we look forward to adding new commercial and research agreements in human health. Led by our Chief Business Officer, Joe Hazelton, we plan to increase our business development focus on opportunities in Animal Health and Alternative Proteins. In Animal Health, our portfolio of vaccines and therapeutic proteins, as well as external licensing agreements and collaborations, is expected to allow the Company to further penetrate the growing global $15 billion animal health vaccine market and enter the billion-dollar therapeutic protein companion animal market."

"Our recently developed Dapibus^TM microbial cell line is gaining interest across multiple applications and industries for the development and manufacture of alternative proteins for world health. We are currently evaluating several opportunities within the global cultured meat industry, which is already a $3 billion market that is still in demonstration scale with over $1.3 billion in industry investments in 2021 alone. Dyadic is dedicating resources and support for existing projects within this rapidly growing market, driven by our fully funded joint development agreement with our Global Food Ingredients collaborator," Mr. Emalfarb concluded.

Recent Company Developments

Focus in three key verticals – The Company is working to further leverage its pipeline and assets and plans to enhance its focus in three verticals: Human Health, Animal Health, and Alternative Proteins (including food, nutrition, and wellness).
Dapibus^TM platform – Dyadic has launched its Dapibus^TM platform, which is a filamentous fungal based microbial gene expression and protein production platform, which is further designed and customized to enable the rapid development and large-scale manufacture of low-cost proteins, metabolites, and other biologic products for use in non-pharmaceutical applications such as food, nutrition, and wellness.
DYAI-100, C1-SARS-CoV-2 RBD (Receptor Binding Domain) Vaccine Candidate
- On July 22, 2022, the Company submitted its Clinical Trial Application (CTA) to the South African Health Products Regulatory Authority (SAHPRA) for expedited review.
- The CTA supports a Phase 1, single-center, single-country, randomized, double blind, placebo-controlled trial to assess the safety and reactogenicity of the C1-SARS-CoV-2 RBD vaccine, produced using Dyadic's C1 platform, administered as a booster at two dose levels to thirty (30) SARS-CoV-2 seropositive healthy participants.
Multiple ongoing research projects aiming to validate the application of C1 as a rapid, efficient platform for manufacturing affordable vaccines, monoclonal antibodies, and other therapeutic proteins against various infectious diseases:
- Third Party C1 Produced COVID-19 Antibody – A non-human primate study completed dosing of a C1 produced COVID-19 monoclonal antibody (mAb) that has demonstrated broad neutralization and protection against Omicron (BA.1 & BA.2) and other variants of concern in hamsters. Data readout is anticipated later this year.
- Influenza and COVID-19 Vaccines – Additional mice trials and analysis are ongoing with C1 produced antigens for a potential seasonal influenza and/or combined influenza / SARS-CoV-2 vaccine.
- Mono and Multi-Valent RBD-based Blended Vaccine – Based on the RBD based antigen cell lines that we have constructed to express Wuhan, Alpha, Beta, Gamma, Delta, and Omicron BA.1 CoV-2 variants, additional animal data is being generated through several preclinical trials using mono and multi-valent blends of C1 produced SARS-CoV-2 RBD variants of concern. Research is ongoing with various collaborators who are conducting animal trials on mono and multi-valent RBD-based blended COVID-19 vaccines for potential next generation pan-coronavirus vaccine candidates that may provide broader protection and longer lasting prevention against a wide variety of coronaviruses than what is presently available in the market.
- Rabies Vaccine – In collaboration with European scientists, the Company has developed a C1 cell line that has expressed an antigen that has the potential to prevent rabies infection in humans after an exposure.
Influenza Neuraminidase (NA) Protein – Developed C1-cell to express high level (~ 800 mg/l in 168 hours) of neuraminidase (NA), in combination with Hemagglutinin (HA) will play an important role in providing broader influenza vaccine-induced protection. Mice trials conducted by Oslo university for NA, like the previously reported HA produced from C1-cells generate high neutralizing antibody levels.
Epygen Biotech – On April 13, 2022, Epygen Biotech, a C1 licensee, received funding from the India government to advance the development and manufacture of its C1 expressed COVID-19 vaccine candidate as well as conduct Phase 1/2 clinical trial(s) in India.
Janssen Collaboration – A fully funded Janssen research collaboration is on track as we continue to develop C1 glycoengineered strains to produce Janssen's therapeutic protein targets.
NIIMBL Collaboration – A fully funded NIIMBL collaboration has completed the first step of the program. The next step of funding has started, which we expect will further validate that our C1-cell protein production platform can be used to produce monoclonal antibodies at unprecedented yields that may lead to a rapid ability to produce medical countermeasures and vaccines in response to future pandemics.
Phibro/Abic Animal Health – On February 10, 2022, Dyadic entered into an exclusive license agreement for a Phibro/Abic targeted disease. The agreement follows the successful proof of concept development work, including animal trials previously completed. Recently, the Company expanded the license agreement to include an additional research project to develop another animal vaccine for livestock.
