Alys Pharmaceuticals Begins Phase IIa Trial for ALY-101 in Alopecia Areata

Alopecia Areata is a chronic autoimmune disorder that leads to hair loss, often causing psychological distress and a reduced quality of life. Despite recent advancements in treatment options, there remains a need for safe and long-lasting solutions for patients suffering from this condition.

ALY-101 is the first clinical candidate from Alys Pharmaceuticals’ pipeline of siRNA-based therapies. The treatment employs a JAK1-targeting siRNA-lipid conjugate, designed to modulate local inflammation with minimal systemic exposure. The drug is administered via intradermal injection, with future formulations in development for trans-epidermal applications targeting other dermatological conditions such as atopic dermatitis and vitiligo.

Scientific Collaboration and Innovation

ALY-101 was developed using a unique siRNA platform co-created with Nobel Prize Laureate Dr. Craig Mello at the RNA Therapeutics Institute at UMass Chan Medical School. Dr. Mello expressed optimism about the application of siRNA technology in dermatology, emphasizing its potential to revolutionize treatments for skin diseases.

Professor Anastasia Khvorova, a leading expert in RNA therapeutics, highlighted ALY-101’s high target specificity, stability, and long-lasting efficacy. Meanwhile, Professor Lars French, Acting Chief Medical Officer at Alys Pharmaceuticals, noted the enthusiastic reception of ALY-101 among clinical investigators, underscoring its promise for infrequent dosing and sustained therapeutic effects.

Clinical Trial and Next Steps

The Phase IIa trial will assess the safety and tolerability of ALY-101 in patients with alopecia areata. Participants will receive scalp injections every four weeks over an eight-week treatment period, with study completion expected by 2026.

This development follows swift regulatory approvals from health authorities in Canada and the United States. Alys Pharmaceuticals remains on track to deliver multiple clinical proof-of-concept readouts by 2027, signaling a potentially transformative advancement in dermatological therapies.
