Alys Pharmaceuticals Launches First-in-Class Clinical Trial for ALY-301, Targeting Chronic Urticaria
Alys Pharmaceuticals, a company specializing in immune-dermatology, has made a significant advancement in the treatment of chronic urticaria by initiating its Phase 1/1b clinical trial for ALY-301. This innovative drug is a first-in-class mast cell selective c-Kit inhibitor designed specifically for chronic urticaria, particularly cold urticaria, which is a subtype of chronic inducible urticaria (CIndU).
Chronic urticaria is a complex and often debilitating condition characterized by the formation of itchy hives and wheals that can persist for extended periods, often severely affecting the quality of life of those affected. Traditional treatments show limitations, providing an urgent unmet need in this market, which is anticipated to reach several billion dollars over the coming decade.
The announcement was made on October 30, 2025, with the dosing of the first subject already completed at the esteemed Charité–Universitätsmedizin Berlin. This milestone highlights Alys’ commitment to offering innovative therapies where current options are lacking. Professor Martin Metz, leading the dermatology team at Charité, emphasized the critical need for effective treatments in this often-overlooked patient population. He stated, “ALY-301's unique ability to exclusively target mast cells offers a promising alternative to conventional c-Kit inhibitors, which may carry safety risks.”
Alys Pharmaceuticals is well recognized in the industry for its pioneering approach. Co-founder Thibaud Portal remarked on the significance of this development, positioning Alys as a trailblazer in immune-dermatology with the introduction of a drug that selectively depletes mast cells while sparing other c-Kit expressing cells, such as melanocytes. This characteristic of ALY-301 not only sets it apart from existing therapies but potentially transforms the landscape of chronic urticaria management.
The clinical trial, referred to as NCT07181369, is designed to be a randomized, double-blind, placebo-controlled study aimed at evaluating both the safety and tolerability of ALY-301 in healthy volunteers, as well as symptomatic patients who have not responded adequately to antihistamine treatments. Moreover, the study will also explore preliminary signs of efficacy in subjects with cold urticaria.
The ongoing trial marks Alys’ second clinical program initiated in 2025 and is part of their ambitious pipeline, which includes a variety of treatments aimed at addressing unmet clinical needs in dermatological disorders like atopic dermatitis and vitiligo among others. Significant patient population engagement is expected as the trial expands to more sites across Germany in the upcoming months.
Alys Pharmaceuticals boasts a robust leadership team, drawing expertise from renowned individuals in the field and backed by substantial funding, which enhances their research capabilities and product pipeline. The company is on track to release multiple Proof-of-Concept (POC) results by 2027, further solidifying its role as a leader in innovative dermatological therapies. As the nation anticipates results, the industry remains hopeful about the long-term implications that ALY-301 might hold for patients suffering from chronic urticaria.
In conclusion, the launch of the ALY-301 trial represents not only an important step for Alys Pharmaceuticals but also a beacon of hope for individuals living with chronic skin conditions. Should the trial yield positive results, it could pave the way for breakthroughs in targeted therapy, dramatically enhancing patient quality of life and making significant strides toward alleviating the burdens of chronic urticaria on a global scale.
