It is exactly more than a hope.Well, basically completely restoring an inner ear function, be it in a lab, is more than "hope to hold on to", it's a fact.
And I personally would be satisfied with a 25% alleviation, not necessarily a cure.
Having a look at it, only two things can happen.
Firstly, Frequency Therapeutics cannot replicate this complete regrowth in a real ear.
Secondly, there is something stopping Frequency Therapeutics from replicating this in a real ear which we don't know about.
At this stage I am going to suggest if it is either of these then it is the latter, although Frequency Therapeutics has demonstrated on multiple occasions that they tend to be able to get FX-322 to work in a real ear.
