I stated I am not 100%, however It was explained to me by a person I know in Pharmaceuticals that...
505B2 is so that a company can do LESS studies in the NDA process. LESS studies means less money needed to be spent. It’s not necessarily a short cut, but it can cut down on some time and money. It’s all case by case basis. He also said the PRE IND is a very important step, but be prepared there may not be this huge PR that you want. It’s more of a set up for the rest of the NDA process.
I’m just passing on what I was told. Do your own research.
However, IMO I think a positive PRE IND could bring in the financial backer interest that we need.
