Monoclonal Antibody Against Prolactin Receptor: A Randomized Placebo-Controlled Study Evaluating Safety, Tolerability, and Pharmacokinetics of Repeated Subcutaneous Administrations in Postmenopausal Women

ABS-201, a prolactin receptor blocker, shows promise in reversing hair loss and graying, with early success in macaques. Current treatments like finasteride, minoxidil, and RU58841 are still widely used, but new options like PP405 are eagerly anticipated.

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

PP405 and ABS-201 are promising treatments for male pattern baldness. PP405 shows rapid hair growth in human trials, while ABS-201 shows significant regrowth in animal studies but is still in early human trials.

The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.

The conversation is about seeking updates on new hair loss treatments, specifically mentioning scube3 and GT20029, with one person mentioning HMI_115 as showing promising results.

The conversation discusses the potential for developing a biologic "DHT sponge" to neutralize DHT in the bloodstream as a treatment for hair loss, suggesting it could be more targeted and have fewer side effects than current treatments like finasteride and dutasteride. Concerns include the complexity, cost, and potential side effects of such a treatment, as well as skepticism about its feasibility and market interest.
