MBF Therapeutics Teams Experts to Develop Effective, Broad-Spectrum Immunotherapeutic African Swine Fever Virus Vaccine

Ambler, PA – MBF Therapeutics, the leader in the development of DNA-based immunotherapeutic checkpoint inhibitor vaccines for the animal health market, has assembled a team of African Swine Fever Virus (ASFV) researchers to develop an effective, broad-spectrum ASFV vaccine, leveraging MBF Therapeutics’ proprietary immunotherapy platform and delivery system.

There is no vaccine or effective treatment for ASFV, which is highly contagious and deadly. Although not yet in North America, ASFV threatens global pork production. ASFV has devastated 50% of the world’s pork production in China, ASFV is rapidly spreading in Asia and Europe. Though ASFV causes high mortality in pigs, thankfully it does not infect humans.

Why an Effective ASFV Vaccine has yet to be Developed  
The ASF viral genome is large and complex, having evolved into more than 20 different genotypes and many more distinct strains. Thus far, attempts to develop an effective ASFV vaccine have taken conventional approaches albeit with incremental improvements, such as gene-deleted modified live virus, protein subunits, and a small assortment of gene-based antigens. Some protection against ASFV has been observed when the strain used to create the vaccine is then used in homologous strain challenge studies.

To date, no vaccines provide broad-spectrum protection against the hundreds of different variations of ASFV. In addition, whereas most vaccines have been designed to elicit antibody responses, it is clear from research that a sustained targeted T-cell response is required for protection against ASFV.

MBF Therapeutics’ ASFV Vaccine Strategy and Proprietary Vaccine Platform Technology:  A Different Approach  
MBF Therapeutics’ ASFV vaccine development strategy focuses on creating DNA-based vaccines that elicit potent T-cell responses to a multiplicity of conserved antigens to achieve broad-spectrum protection. MBF Therapeutics’ vaccine platform technology comprises a proprietary combination of three components:

  1. Delivery component - CaptaVax™, a delivery system based on functionalized calcium phosphate nanoparticles size-optimized for uptake by naive innate antigen presentation cells to effectively stimulate strong innate trained immunity.

  2. Immunomodulator component - Species-specific stimulatory immunomodulators and checkpoint inhibitors that elicit potent antigen-specific antibodies and memory T cells.

  3. Antigen component - Disease-specific, protective T- and B-cell antigens.


MBF Therapeutics’ Team of Scientific Experts are Poised to Transform ASFV Vaccine Development
MBFT is collaborating with a diverse and expert group of scientists and molecular biologists, with deep experience in viral genomics, veterinary immunology, ASFV research, and vaccine design. This consortium of academic and industry specialists is focused on applying immunotherapeutic advances to solve this challenging infectious disease threat.  The urgent need for a different approach to ASFV prevention drives this team to explore novel strategies, for which MBFT platform technology has the potential to transform vaccine design and manufacture.

Joining Lorraine H. Keller, PhD, CSO, MBF Therapeutics Inc., are:

  • Megan C. Neiderwerder, DVM, PhD, Assistant Professor, Kansas State University, College of Veterinary Medicine, Manhattan, KS

  • Raymond “Bob” Rowland, PhD, Professor of Diagnostic Medicine and Pathobiology, Kansas State University, Manhattan, KS

  • Luca Popescu, DVM, PhD, Senior Scientist, MRIGlobal, Kansas City, MO

  • Tobias Kaeser, PhD, Assistant Professor, Swine Immunology, North Carolina State College of Veterinary Medicine, Raleigh, NC

  • Malla Padidam, PhD, President, OneWorld Biotech, Inc.


Diamond Animal Health, Inc., Des Moines, IA, will provide vaccine manufacturing. Southwest Research Institute in San Antonio, TX will provide the CaptaVax nanoparticles for these studies.

“Complex and devastating animal diseases like ASFV can impact our agriculture globally, and dramatically affect our food supplies,” said Peter K. Dorhout, vice president for research at Kansas State University. “At K-State and NC State, our mission as land-grant universities is to be research partners with private sector companies to develop cutting-edge science to improve people’s lives. These therapeutics, and the teams that created them, are examples of what we can accomplish when we work together.”

According to MBF Therapeutics’ Executive Vice President of Business Development Ronald Cravens, MS, DVM, “We believe that by utilizing a collaborative approach – together with our proprietary vaccine platform technology and vaccine development strategy – MBF Therapeutics’ innovative vaccine design platform will contribute to developing a truly effective, broad-spectrum ASFV vaccine.”
