Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.
IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.
PP405's phase 2a trial results were presented, focusing on safety and pharmacokinetics, with a future meeting planned to share the full dataset. The trial includes a randomized controlled portion and an open-label extension, with no indication of phase 2B completion.
PP405 shows initial promise for treating androgenetic alopecia, with safety confirmed in early trials, but skepticism remains due to limited data. Further trials are needed to determine its true efficacy and potential market impact.
ABS-201 shows promise for male hair regrowth by blocking the prolactin receptor, with higher expected efficacy than current treatments. The discussion also covers dosing differences between macaques and humans for hmi115, highlighting a significant dosage disparity.
