Histogen Phase 3 Trials on Men Begin in Mexico

Update 2020: Histogen merging with Conatus Pharmaceuticals.

Update 2019: It seems like Histogen’s male hair loss product (HST001) clinical trials never worked out in Mexico. A new article from Histogen states that Phase 1b trials for HST001 (Hair Stimulating Complex) would start later in 2019. Note that their female hair loss product is called HSC660.


Earlier today, commentator “Bekoo” posted some groundbreaking news about Histogen in regards to their men’s hair loss product. The information he posted was part of an article that appeared a few days ago in the San Diego Tribune on July 12th 2018. Note that Histogen is headquartered in San Diego, so the company is often covered in the city’s main local newspapers.

The title and gist of this new article is in regards to Histogen’s women’s hair loss product (HSC660) trials starting. I already discussed this development recently. So even though it was in my Google alerts, I was never planning to read the article in it’s entirety… until “Bekoo” saved us and posted his findings today.

Histogen Starts Phase 3 Trials in Mexico

  • By far the biggest news is that Histogen has started Phase 3 clinical trials in Mexico for its men’s hair product. This product is called “an earlier version of HSC660” in the San Diego Tribune article, so might be slightly different from the newer women’s HSC660.

Note that in 2016, Histogen estimated that their men’s  hair loss product would be available in Mexico in 2018. They were planning to start Phase 3 trials in Mexico “soon” per that 2016 post of mine. So it looks like they got delayed by 1.5 years or so. Better late than never of course.

  • Also, per CEO Dr. Gail Naughton, they anticipate success with these Phase 3 trials and are looking towards commercialization:

“We’re in very late-stage negotiations with some huge retail partners. A deal should be concluded in the next few months.”
