MINNEAPOLIS, MN, USA I May 06, 2020 I Predictive Oncology (NASDAQ: POAI) has, with the announced acquisition of Soluble Therapeutics, Inc. and the subsequent partnership and licensing of a novel nanoparticle vaccine platform recently developed by Dr. Daniel Carter, entered the race to develop a COVID-19 vaccine.  The groundbreaking vaccine technology being developed by Dr. Carter is based on a self-assembling nanoparticle called NSP-10 (NSP is Non Specific Protein) which follows a foundational vaccine platform developed earlier by Dr. Carter and his team, using another self-assembling protein called ferritin (1), an iron storage protein found in all living things.  The ferritin platform is currently exploited by NIH in its exploration of the universal flu vaccine which completed phase I clinical trials earlier this year and is currently recruiting for a second Phase 1 trial on a modified version of the ferritin self-assembly universal vaccine (2,3). POAI has entered into an agreement with Dr. Carter under which POAI is licensing this technology, subject to certain conditions including additional documentation.

NSP-10 is a newly patented self-assembling nanoparticle technology sometimes referred to as virus-like particles or VLP (4).  Called a nanoparticle because of its small size, typically 10-12 nanometers in diameter and self-assembling because a single small subunit has the built-in “self-assembly” instructions to form engineered complex Virus Like Particle (“VLP”) assemblies.  They can be thought of as “smart-Legos”, so that when a large number are thrown together, they automatically self-assemble into the same large complex structures – in this case the vaccine.  In the case of a DNA vaccine, the DNA instructs the body’s cells to make the Legos in mass which assemble into numerous vaccine particles. 

This is a brand-new technology, published on January 4th, 2020 in Journal of Nanomaterials and the associated patent has just received notice of allowance from the US Patent Office in February 2020 (4,5).  In addition to its publication during the beginning of the current coronavirus epidemic, its self-assembling elements are coincidentally based on an obscure gene regulatory protein found in the original SARS-CoV-1 coronavirus.

According to Dr. Carter, principal inventor of the ferritin self-assembling nanoparticle platform (1), now widely applied by many, including NIH, to other applications and principal inventor of the new NSP10 approach, “NSP10 is a ‘game changer’ vaccine platform with significant advantages over current state-of-the-art.  These game changer properties have also been validated with SARS-CoV-2 vaccine candidates – resulting in extraordinary animal titers against the coronavirus spike protein which is required for viral infectivity – all with a simple injection of small quantities of DNA.”

  1. NSP-10 is especially interesting because it has structural properties permit the rapid creation of nanoparticle vaccines for a broad spectrum of viruses and microbes in a “click and play” type design process.
  2. They exhibit an ability to induce exceptional vaccine titers as either a protein or DNA-based vaccines, often as much as 10 to 100 times higher titers (more antibodies against the target) than traditional vaccines; and
  3. They have the potential to rapidly move an effective DNA vaccine into the field with numerous advantages in safety, production, stability, distribution and administration.

The NSP COVID-19 vaccine has produced atypically strong titers against the coronavirus spike protein in small animals using a single small dose of plasmid-based DNA.  Plasmid DNA is extremely safe, non-replicating, non-viral and can be produced in large quantities by established methods.

Vaccine in support of a Phase I clinical trial is in production with expected delivery later this month.

Predictive Oncology’s next step, in support of its partnership with Dr. Carter, is seeking quotes for a Phase 1 clinical trial from one or more of the BARDA approved CROs.

There is no assurance that a vaccine will be successfully developed using this technology, or that definitive documentation of all arrangements will be completed. As previously announced, POAI has taken over the operation of Soluble Therapeutics, which is also working on applications that can aid in COVID-19 development, and POAI this acquisition to be completed in the first part of May.

Helomics applies artificial intelligence to its rich data gathered from patient tumors to both personalize cancer therapies for patients and drive the development of new targeted therapies in collaborations with pharmaceutical companies. Helomics’ CLIA-certified lab provides clinical testing that assists oncologists in individualizing patient treatment decisions, by providing an evidence-based roadmap for therapy. In addition to its proprietary precision oncology platform, Helomics offers boutique CRO services that leverage its TruTumor(TM), patient-derived tumor models coupled to a wide range of multi-omics assays (genomics, proteomics and biochemical), and an AI-powered proprietary bioinformatics platform to provide a tailored solution to its clients’ specific needs. Predictive Oncology’s TumorGenesis subsidiary is developing a new rapid approach to growing tumors in the laboratory, which essentially “fools” cancer cells into thinking they are still growing inside a patient. Its proprietary Oncology Discovery Technology Platform kits will assist researchers and clinicians to identify which cancer cells bind to specific biomarkers. Once the biomarkers are identified they can be used in TumorGenesis’ Oncology Capture Technology Platforms which isolate and help categorize an individual patient’s heterogeneous tumor samples to enable the development of patient specific treatment options. Helomics and TumorGenesis are focused on ovarian cancer.
