Subgroup Analysis of Efficacy of Upadacitinib in Adults and Adolescents With Severe Alopecia Areata From the UP-AA Phase 3 Program

An arthritis drug restored significant hair in people with alopecia areata, but it is not effective for male pattern baldness. The drug, Upadacitinib, has serious side effects and is expensive.

KX-826 Phase II results show that a 0.5% concentration performs better than 1% for treating male pattern baldness. Concerns about receptor upregulation from long-term DHT antagonism were mentioned.

PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.

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.

A new hair loss treatment, PP405, showed promising Phase 2a results with 31% of patients experiencing over 20% hair density increase without systemic absorption, avoiding hormonal side effects. The treatment is expected to be expensive, with Phase 3 trials starting mid-2026, and there is skepticism about the data's strength.

PP405 trials have completed phase 2a, showing promising results with a 31% stat for hair density increase, and are moving directly to phase 3. Detailed results will be presented at a medical conference in 2026.
