Nucleo - Whilst I agree with your 'err on the side of caution' statement I would refer you back to the Autifony statement posted above = 'an effective drug for tinnitus is critically needed' - I think that says it all.
I work for, and have worked for some of the world's largest pharmaceutical companies for the last 14 years and I can assure you when it comes to a 1st in class drug for an unmet clinical need the pharmaceutical company involved will try to push it through MHRA and NICE as quickly as possible. Yes there is a lot of regulatory hurdles to get through, yes this takes time and negotiation by the pharmaceutical company involved (and it is not always successful) but they will give it their best shot.
So 'err to caution' - yes, that is the sensible thing to do. Will AUT00063 (if it gets through it's clinical trials successfully) be pushed through all the regulatory hurdles ASAP, I think so.
