Novel Anti-Müllerian Hormone Receptor 2 Binding Peptide Prevents Chemotherapy-Related Ovarian Follicle Loss in a Mouse Model

ABS-201 may block prolactin receptors in hair, potentially reducing androgen receptors and affecting hair loss. It could also aid collagen synthesis and stem cell pathways, similar to GHK-Cu.

Hmi115, a prolactin receptor blocker, showed promise for hair growth, but results from Phase 2 trials have not been published. ABS-201, an AI-based analog, is expected to begin trials in December 2025, while commercialization of treatments like PP-405 is anticipated around 2027.

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.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

Stress can lead to hair loss by affecting hair-follicle stem cells, and this loss is harder to recover from if one has male pattern baldness (MPB). Treatments like finasteride and minoxidil are used to address hair loss, but stress-related hair loss differs from androgenic alopecia.

Chime Biologics and Hope Medicine are speeding up the launch of a first-in-class antibody drug, HMI-115, for endometriosis and androgenic alopecia. The treatment involves a series of subcutaneous injections, has shown promising results in phase 1, and continues to promote hair regrowth even after the treatment is stopped.
