Protacs In 2025: From The Laboratory Concept To Clinical Breakthrough

Promising hair loss treatments in clinical trials include Pyrilutamide, GT20029, CB-03-01, and PP405, with potential market releases between 2027 and 2029. Hair cloning remains experimental and expensive, while existing treatments like finasteride, minoxidil, and microneedling continue to be used.

New hair loss treatments include Breezula, PP405, ET-02, KX-826, GT20029, VDPHL01, and CosmeRNA, with some showing promise in reactivating stem cells and reversing greying. Breezula and VDPHL01 are highlighted as potential add-ons or alternatives to current treatments like finasteride and minoxidil.

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.

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.

Kintor Pharma completed patient enrollment for a Phase II trial in China for GT20029, a potential new treatment for hair loss. Some believe GT20029 could replace finasteride if effective, while others discuss finasteride's limited efficacy and potential underreported side effects.

SCUBE3 and GT20029 are potential treatments for hair loss, with SCUBE3 stimulating hair growth and GT20029 protecting against DHT. A combined approach using SCUBE3, finasteride or dutasteride, and later GT20029 could provide a comprehensive treatment for androgenetic alopecia.
