Predictive Oncology (NASDAQ Symbol POAI) is licensing and partnering this groundbreaking NSP10 technology in the race to develop a vaccine for development

MINNEAPOLIS, May 14, 2020 (GLOBE NEWSWIRE) -- Predictive Oncology (NASDAQ: POAI)  has, with the announced acquisition of Soluble Therapeutics and the subsequent partnership and licensing of a novel nanoparticle vaccine technology platform recently developed by Dr. Daniel Carter, entered the race to develop a COVID19 vaccine.  The ground-breaking vaccine technology is based on a self-assembling nanoparticle called NSP10 which follows a foundational vaccine platform developed earlier by Dr. Carter and his team, using another self-assembling protein called ferritin (1).

The unique trimeric fusion points on NSP10 stabilize the proper native stem folding and present SARS spike protein to the immune system in exactly the same way as it occurs on the COVID19 virus, which in turn is expected to produce the desired results: immunity to COVID19.


NSP10 Vaccine Technology: How Does it work and Why is it a “Game Changer”?

NSP10 Nanoparticle has special surface properties that allow for the rapid design and display of viral receptor stems for virtually any virus, making it extremely versatile. “Couple these properties with the extraordinary immunogenic properties and you have a potentially “game changing” technology,” according to Dr. Joel Dobbs, a retired pharmaceutical industry executive, who is now Executive-in-Residence at UAB’s Collat School of Business, “this is a truly transitional technology that could change the way vaccines are made in the future.”

Previous vaccine studies of NSP10-based Nanoparticles in rabbits produced exceptionally high titers against a herpes viral protein called glycoprotein D, normally non-highly antigenic (Titer refers to the number of times the blood serum can be diluted and still react with the virus antigen). Titers in this case ranged from 1:1,000 with a simple injection of 500 micrograms of plasmid DNA, to as much as 1:25,000 after a second booster (third injection) - all without the use of adjuvants or transfection agents (2).  To our knowledge, this is unprecedented and revolutionary for a DNA vaccine. The exact reasons why the NSP10-based Nanoparticles exhibit these properties is still a subject of study, but scientists know that nanoparticles are processed differently by the immune system (3) and smaller nanoparticles can often produce higher titers – NSP is one of the smallest currently evaluated.

The level of titer is important for many reasons, for example, earlier animal experiments with vaccines focused on severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) found that low antibody levels could potentially lead to dysfunctional immune responses, increasing infection and damaging the lungs (4). In addition to enhanced protective immunity, stronger titers mean that it takes less vaccine per dose which has added advantages in safety and production scale. In the special case of  NSP10-based vaccines, as it translates to humans, this could mean that a single gram of plasmid DNA can potentially immunize as many as 2,000 people, perhaps more.  According to Dr. Daniel Carter, the inventor of this technology (5), “this suggests that if we see similar titers in humans, no atypical resources or capabilities are required to manufacture the vaccine at a sufficient scale to impact the pandemic.”  For example, a single bacterial fermentation at commercial scale can in a span of 2 to 3 days, produce enough raw material to eventually immunize millions of people - “merge this with the well-established processes for purifying injectable-grade plasmid DNA (which can also be done in short order)  and you have the potential for a disruptive game changing technology,” said Dr. Carter.
