there is still a lot of risk and at least 1-2 years before that risk can be sufficiently dispelled.
Keep all risks in mind no matter how optimistic you might be.
True, there is risk! One approach might be to assess the risks for THIS company, as opposed to generic biotech risks, and then invest at a level that is appropriate with respect to the perceived risk.
I'm hoping that it will not take 1-2 years to get data sufficient to substantially reduce if not completely dispel concerns about the viability of the platform.
