The FDA Drug Development Phases Model

Magna, can you take us through the the phases of fta drug approval? Yes. O, it's always rigorousd we start with the pre clinical study. Es are usually the animal studies, the basic science bench research. We start with phase one, so this is where you take a small number of healthy subjects to study the pharmicology and side effects. Then there's the face three and so this is a randomized control trial comparing the drug to existing therapies. And then finally, you get to face four, and which is the ongoing trials after f dapproval to identify any long term effects.
