A new hair loss treatment using dissolving microneedles was found to speed up hair growth and was more effective than daily use of common hair growth drugs.
The GT20029 tincture, a topical androgen receptor degrader, showed significant hair growth and good safety in a China Phase II trial for male androgenetic alopecia (AGA), with the 1% dose twice weekly identified as optimal. The company plans to initiate Phase III trials in China and Phase II in the U.S., and the treatment also shows promise for acne.
The user is considering switching from finasteride to dutasteride for hair loss. They are unsure if GT20029 can regrow hair, particularly on the temples. Another user mentions that regrowth on finasteride can take up to 2 years.
Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.
The conversation discusses the approval of Kintor Pharmaceutical's AR-PROTAC (GT20029) for clinical trials in China for acne and androgenic alopecia. One user expresses optimism about new treatments being developed and seeks clarification on how the new drug works, specifically if it temporarily degrades the AR protein to reduce DHT sensitivity in hair follicles.
GHK-Cu is a potent inhibitor of the type 1 5-alpha reductase enzyme in hair follicles, which may reduce hair loss without the side effects associated with type 2 5-alpha reductase inhibitors. The user previously experienced side effects with 5-alpha reductase inhibitors and is considering GHK-Cu as an alternative.
