Yes, I expect things to take a while. Even RepliCel, who have progressed the farest in everything including licensing and trials, recently removed the estimate for availability of their treatment in Q4 2019 from their website. So they will likely take longer.
So, the good news is: The cure has actually been found. Histogen injects Wnt7a, RepliCel injects DSC cells, both work.
The bad news: We will not be getting it anytime soon.
By the way, as I explained
in this post, Histogen was put out of business for a couple of years due to a lawsuit which put their operations on hold and ate up all their capital. Histogen's Phase 3 trials would be over by now if some a**h** hadn't decided to sue them. Both Histogen and RepliCel estimated market availability 2 years after the end of phase 3 trials, which would - in theory - have made Histogen's HSC available by the end of 2016. But a lack of finances as the result from the lawsuit was the problem. Now, Histogen hasn't even commenced Phase 3 yet.
I personally think, if the male pattern baldness foundation idea actually works out, its focus should be to provide RepliCel and Histogen with funding. Both approaches are proven to work and potentially give unlimited regrowth, but Histogen's loss of capital has set them back by more than 2.5 years. If they run out of capital to advance their trials again, this will introduce additional delay. And these two companies are the farest in development of an actual treatment, so our best chance of receiving treatment.
