Past and Future Strategies for GPCR Deorphanization

The conversation discusses the delay in the PP405 Phase 2 study results, now expected by the end of 2025, and skepticism about research practices. There is also mention of optimism for Amplifica's AMP303 and a topical treatment in early testing.

The conversation discusses potential hair loss treatments, including clascoterone, GT20029, ET-02, VDPHL01, and PP405, with hopes for new options by 2028. Current treatments like minoxidil and finasteride are expected to remain effective, with clascoterone and VDPHL01 as promising alternatives.

Promising hair loss treatments in 2026 include GT20029, a topical androgen receptor degrader, and VDPHL01, an extended-release oral minoxidil, both offering safer alternatives with fewer side effects. Other treatments like sublingual minoxidil, OND-1, JW0061, TDM-105795, and AMP-303 are also being explored.

People are discussing their reactions if PP405 fails in phase 3 trials, with some expressing skepticism and others holding onto hope for future treatments like GT20029 and Breezula. Many mention continuing with existing treatments like minoxidil and finasteride, while others express disappointment and consider alternative solutions.

Pelage plans to release phase 2 results and start phase 3 trials for PP405 in 2050, but skepticism remains due to past delays and unfulfilled promises. Users express frustration over the lack of progress in hair loss treatments, mentioning Minoxidil, finasteride, RU58841, CB-03-01, and Fluridil.

GT20029 is a topical treatment that degrades androgen receptors to prevent hair thinning and loss, potentially offering fewer side effects than systemic treatments like finasteride. Concerns include its impact on hair texture and potential systemic effects, with market availability speculated in 3 to 5 years.
