Nano-PROTACs: State of the Art and Perspectives

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.

PP405 shows promise for hair regrowth by manipulating stem cell characteristics and lactate dehydrogenase, with Phase 2a trials pending. Google Ventures' $15M investment suggests confidence, but results and market availability remain uncertain.

A user is interested in Absci's AI-driven antibody platform, ABS-201, for treating androgenetic alopecia, which shows promising preclinical results and potential for hair regrowth and pigmentation restoration. However, concerns are raised about the drug's development timeline and its advantages compared to existing treatments.

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.

Exploring hair loss treatments beyond DHT, including Minoxidil, pyruvate, Gt20029 targeting androgen receptors, and vasodilators. Other options like Kx826, adenosine signaling, growth factor topicals, and microneedling are also discussed.

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.
