That's a bare minimum of 2 years just to get through phase 3, if everything works perfectly. Given this company's history of 11 years and still no clinical trials beginning, I'd say perfect is the last thing that their process has been.
That timeline is an absolute rare, best case scenario for a big pharma company with massive resources.
A company like SBFM takes at least 3x those time frames to complete each of those steps.
That's not a knock on SBFM, that's a fact for all pre-rev biotechs.
