Yes it did. The way they stopped the the protein CXXC5 from messing up the wnt pathway is by using something called PTD-BDM that get's to the place where CXXC5 "docks" on to an protein (Dvl) in the wnt pathway and so blocks CXXC5 from "docking". So you would need to keep blocking CXXC5 meaning you'd need a continual supply of PTD-BDM.
So at worst this would be a daily application. At best, it could be that, due to how CXCC5 expression seems to be elevated by a negative feedback loop, once you've got back to NW0 your DP cells have effectively been "reset", meaning they're back to how they were the very last day before DHT started doing it's thing. So you could have to only use this for a period every 6 months or a year, or maybe even more, to effectively maintain full density.
Again, I'm trying very hard to hype this, but I think it seems like this approach is a whole different paradigm from finasteride / minoxidil treatment. We're not just restricting the amount damage being done (finasteride) or slamming down the gas on a failing engine (minoxidil), we're actually diffusing the bomb.
I'm still not clear on what the side effects could be that would limit the use something of like PTD-BDM, but the study seemed to suggesting that there wasn't anything observed. The study was received on the 16th September 2016, so it's been at least over a year since they've finished. It would be really interesting to know if they've running, or have run a safety trial.
