they call it optimization study i call it not good enough results let's find out if we can do better. those of us who expect to have a full head of hair again with follica don't put your hopes too high
and the rest of us call it "You don't know what the hell you're on about" as usual. All of the hate you express toward this company is solely based on the fact that it's not who you want to "win".
This kind of thing is not uncommon. We know that they have tested various compounds over the years, and there are obviously a number of parameters to consider pertaining to the wounding. You absolutely want to make sure you have the best protocols to achieve optimal results, all across the board, for every patient, as you go into the last trial.
Next item: As Occulus has explained before and Swoop had posted way back, PureTech did their own market research and found that the main reason most people don't use finasteride or rogaine is not because "sides" or other sh*t, but because it doesn't provide satisfactory regrowth. Therefore, they know they will have to produce something better.
You really think these people, who already have an FDA-approved weightloss pill coming out in the next year or so, got to where they are by being f*****g idiots? You think they've poured 10s of millions into something that isn't going to give them serious returns?
Lastly, and best of all: The ship has already sailed that this will work to grow new hair, and quite substantial amounts of it in fact. There is plenty of science that proves it. sh*t, just recently there was a study that found it's even possible to grow hair in the scalp of an 80 year old man with wounding and no chemical assistance. Thus, it is obvious that with perfection of the technique, and stimulation with different compounds (some of which may yet be unknown to us), this is a perfectly viable method of growing new hair. It's also a fact that it can repeated.
Now, you can argue that maybe it won't be permanent, people will likely see a bit of variance in results, it may depend on age, it's a "bridge" technology, etc. and you may be right.
But take it from me, a guy who doubted this before bothering to read more up on it: Anyone who thinks that this tech isn't worthwhile, and our nearest solution, is talking out of their ***.
It astounds me how people here actively bet against their own best interests.
