10 Billion is my estimate for their worth at first successful phase 1 human trial. Since their platform is of the type that is transferable to almost any virus, then efficacy and lack of toxicity would allow for significantly more worth with any successful trials thereafter.
The science is REAL, the efficacy demonostrated in animnal biological systems, of which humans are a part, is REAL. Regardless of what one thinks about management, management made that happen, and IT, the REALNESS of the SCIENCE is what is worth the BILLIONS in the long run.
