FULL FDA approvals cost 100's of millions at the ...."end of the day" ....
Believing you are going to locate the "holy grail" ( FDA approval ) spending peanuts is a "naive thought" ( IMHO )
It takes money to get to the finish line, it is a rather simple concept.
My experience is that the more "focussed" the funding, the better chance of success...pour example "are financing taken or simply sold to the public at elevated prices"?
Watch and learn...
AND alway do your own due diligence and consult a professional on any money matter > $100 CAD or USD. The internet is NOT the place to get advice. IMHEO
FWIW
