PRLR and PCCA Variants Associated with Hair Length in Brangus Heifers

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.

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.

A user applied the 8T3 product for hair loss, targeting LPP and AGA, and plans to update on its effectiveness. The product uses a saline buffered phosphate vehicle, suitable for those intolerant to ethanolic vehicles.

PP405 is a safer alternative to JXL069 for hair loss treatment because it penetrates the skin effectively and degrades in the blood, avoiding systemic toxicity. JXL069, when forced into the body, can cause dangerous side effects like lactic acidosis due to its inability to degrade safely.

Pelage Pharmaceuticals raised $120M for their hair loss treatment, PP405, showing strong investor confidence despite limited data. There is skepticism about its efficacy and long-term effects compared to treatments like GT20029.

JXL069, also known as PP405, did not lead to hair regrowth after a year of testing. The lack of results may be due to formulation issues, leading to a final attempt with an improved vehicle.
