In February, someone e-mailed me a news link on Technoderma (China)’s site. At the bottom of that page devoted to dermatitis was a section on androgenetic alopecia (AGA):
“Previously, the company has completed the phase I clinical trial of TDM-105795 tincture in androgen alopecia (AGA), and is expected to initiate the phase II clinical trial in the middle of March 2023.”
On the company’s site, it says that TDM-105795 is a “first-in-class” small molecule thyromimetic drug candidate. Thyromimetics are synthetic analogs of thyroid hormones.
A 2022 study from China found that Tehnoderma’s thyroid hormone receptor agonist promotes hair growth in mice. They called the molecule thyroxine receptor agonist TDM 10842. Note that the hair growth resulted via “the early induction of anagen” so it is not brand new hair. The researchers suggest a potential mechanism to be the activation of Wnt/beta-catenin and Hedgehog pathways.
The Thyroid Hormone and Hair Growth
- A 2016 study from Europe concluded that the thyroid hormone analogue KB2115 (Eprotirome) prolongs the human hair growth cycle (i.e., anagen).
- A 2010 US study found that a thyroid hormone receptor beta subtype-selective thyromimetic 5 was efficacious in mouse and monkey hair growth after topical application.
- A 2008 study even concluded that thyroid hormones (besides prolonging the anagen phase of the hair cycle) impact hair pigmentation.
Technoderma Begins Phase 2 Trials
Earlier today, someone e-mailed me that Technoderma just began recruiting for their Phase 2 clinical trials in the US per a Reddit post. They are moving just as fast as the other Chinese company Kintor Pharma.
They are looking for 72 volunteers. The sponsors and collaborators are listed as Technoderma Medicines Inc and Therapeutics Inc (a dermatology contract research organization).
The clinical trial page lists three research locations in Oregon, Texas and Virginia. However, per the Reddit post (which in turn comes from a Discord announcement), there are thirteen cities across nine states where you can get recruited to participate. I will not post the city names or the contact person’s e-mail here for now, but you can check the Reddit.
I posted this now because the 72 participant capacity will likely fill up very fast.
