Dyadic and Scripps Research Collaborate on Rapid-Response Hantavirus Antibody and Vaccine Development
Collaboration Leverages Prior Andes, Marburg and Ebola Virus Research and Dyadic’s C1 Platform Capabilities for Fast, Scalable Biologic Production
JUPITER, Fla., May 28, 2026 (GLOBE NEWSWIRE) -- Dyadic International, Inc. (“Dyadic,” “we,” “us,” “our,” or the “Company”) (NASDAQ: DYAI), d/b/a Dyadic Applied BioSolutions, a biotechnology company focused on the development and commercialization of scalable microbial protein production platforms for use across life sciences, food, nutrition, industrial, and biopharmaceutical applications, today announced that Dyadic Applied BioSolutions and researchers at Scripps Research are collaborating to evaluate monoclonal antibody and vaccine candidates targeting hantaviruses, including Andes virus, a hantavirus strain associated with Hantavirus Pulmonary Syndrome (HPS), a severe and potentially fatal respiratory disease in humans.
A series of recently reported hantavirus and Ebola cases worldwide have underscored the importance of pandemic preparedness and highlighted the need to improve the speed, scalability, flexibility, and cost-effectiveness of biologic manufacturing during rapidly evolving public health events. The collaboration builds upon Dyadic’s prior Andes virus monoclonal antibody work and combines the complementary expertise of Dyadic and Scripps Research to further assess the potential of Dyadic’s proprietary C1 platform for rapid development timelines, high-productivity microbial fermentation, large-scale manufacturing, and biologic production intended to support future infectious disease preparedness.
Dyadic’s microbial fungal-based C1 platform has been applied to multiple biologic modalities, including recombinant vaccine antigens and monoclonal antibodies targeting RSV, malaria, the Andes virus, Ebola, and Marburg, which is similar to Ebola and comes from the same family of viruses—the Filovirus family, and has demonstrated in preclinical studies the ability to produce monoclonal antibodies with binding, neutralization, and efficacy characteristics comparable to those generated by traditional mammalian expression systems.
In prior Andes virus-related work, Dyadic developed a C1 strain expressing the recombinant anti-Andes virus monoclonal antibody rANDV-44, where, Dyadic believes, the data generated demonstrated virus neutralization activity comparable to ExpiCHO-produced material in a pseudovirus neutralization assay.
Dyadic has also previously demonstrated GMP-compliant manufacturing and Phase 1 clinical evaluation of biologics produced using its C1 platform as part of earlier infectious disease initiatives. The Company is currently involved in multiple funded biopharmaceutical collaborations, including programs supported by the Gates Foundation and the Coalition for Epidemic Preparedness Innovations (“CEPI”) in collaboration with Fondazione Biotecnopolo di Siena (“FBS”), aimed at accelerating recombinant protein vaccines and monoclonal antibody development workflows using the C1 platform.
Dyadic’s C1 platform was previously included in the European Union-supported Zoonosis Anticipation and Preparedness Initiative (“ZAPI”), a five-year pandemic preparedness program involving leading global human and animal health organizations focused on accelerating biologic manufacturing technologies for emerging infectious diseases. Building upon the progress achieved from ZAPI, Dyadic’s more recent and ongoing funded collaborations supported by the Gates Foundation, CEPI, FBS, and activities associated with the EU Vaccine Hub continue to advance rapid, scalable biologic manufacturing approaches using the C1 platform to help address many of the manufacturing bottlenecks revealed during COVID-19 and other emerging infectious disease outbreaks.
Together, these programs continue to generate data that support the potential advantages of the C1 platform, including compressed development timelines, scalable microbial fermentation, and streamlined manufacturing processes. Additional studies have shown that C1-produced monoclonal antibodies can achieve binding and neutralization properties comparable to antibodies produced in traditional mammalian systems.
“One of the key lessons from recent global outbreaks is that scientific innovation alone is not sufficient — manufacturing flexibility, scale and speed are also critical,” said Jiang Zhu, Professor at Scripps Research. “Collaborations that bring together advanced antibody and antigen research with rapid biologic production technologies may help strengthen preparedness for future infectious disease threats.”
Dr. Zhu continued, “My laboratory at Scripps Research has developed proprietary structure-based protein designs optimized for conformational integrity, trimer closure, and antigen quality. In parallel, innovative expression technologies such as Dyadic’s C1 platform may offer opportunities to further evaluate faster, more scalable and potentially lower-cost approaches for the development and manufacture of complex biologics targeting emerging infectious diseases.”
“COVID-19 demonstrated that manufacturing scalability and deployment speed remain critical challenges during global outbreaks,” said Mark Emalfarb, Dyadic’s Chief Executive Officer. “Our collaboration with Scripps builds upon prior hantavirus-related work and reflects our broader strategy of partnering with leading research institutions and global health organizations to evaluate how we anticipate the C1 platform will contribute to future pandemic preparedness initiatives.”
Mr. Emalfarb continued, “Importantly, these activities continue to be pursued through grants, sponsored research, and strategic collaborations, allowing Dyadic to further validate the C1 platform in a capital-efficient manner while maintaining our primary commercial focus on non-pharmaceutical protein products and industrial-scale biomanufacturing opportunities.”
Dyadic and Scripps plan to jointly explore external partnership and non-dilutive funding opportunities to support additional development activities related to monoclonal antibodies, and vaccine candidates, and broader infectious disease preparedness applications.
Dyadic recently highlighted growing commercial activity with recombinant proteins and enzymes in non-pharmaceutical applications, including animal-free proteins for life sciences, cell culture media, nutrition, wellness, and industrial markets.
