That interview is over a year old - they updated it after Devon died - in fact you can't find any trace of follicept on prometheon's website anymore. They had an informal trial going on for about 6 months (like Fidia), which they kept extending waiting for results that never appeared (maybe also like Fidia?).
There is research that suggests IGF-1 promotes hair growth, which is the reason they tested it. The researchers even admitted they wouldn't have come forward with it/posted on forums if they knew how much attention it would get (probably what Fidia is thinking now).
If Fidia was seeing an impressive result, all they'd have to do is release a simple press release saying such; a new, effective hair loss treatment would be like printing money. I just don't think anything's gonna come of this.
