Key takeaways:

Alphyn Biologics reported positive results for topical AB-101a in a phase 2a clinical trial in pediatric patients with mild to moderate atopic dermatitis.
“We are extremely pleased with the pediatric results,” Neal Koller, CEO of Alphyn, said in a press release. “The improvements these children experienced in the severity of disease and symptoms are particularly remarkable. AD can be a lifelong chronic disease, and options are needed for long-term continuous use.”
The randomized double-blind study evaluating AB-101a, a novel topical candidate developed to treat immune and bacterial components of AD, met all primary and secondary efficacy endpoints while maintaining a positive safety profile.
Twenty-seven participants in the study were between the ages of 2 and 17 years old. After 4 weeks of treatment, approximately 52% of those who received AB-101a achieved IGA score improvement compared with 0% of those who received vehicle control.
Key secondary endpoints were also met. Approximately 35% of those who received AB-101a- achieved EASI 75 compared with 0% who received vehicle. Additionally, 32% had an improvement in body surface area, and 62% had an itch score improvement of at least 4.
No serious adverse events were reported. Adverse events for AB-101a included mild transient stinging in three participants.
The company plans to initiate a phase 2b trial in the U.S., Europe, Canada and Australia.
