About

This is a dose escalation study to test the safety, tolerability and preliminary efficacy of ASN002 in people with moderate to severe atopic dermatitis (AD).

Full description

This study is a dose escalation study to determine a safe and tolerable dose of ASN002 for people with moderate to severe atopic dermatitis. This study will also characterize the pharmacokinetics and pharmacodynamics of ASN002 through blood sampling and skin biopsies. Subjects will also be assessed for improvement in their atopic dermatitis. There will be a screening period (up to 30 days) and a treatment period for 4 weeks with a 14 day follow up with an end-of-study visit.

Enrollment: 36 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: Accepts Healthy Volunteers

• Written informed consent obtained prior to any study-related procedure being performed;
• Male or female, 18≤ years and ≤75 years of age with chronic AD for at least 6 months.

• Has a body mass index (BMI) ≤35 kg/m2
• History of inadequate response to topical corticosteroids or calcineurin inhibitors as treatment for AD within 1 year before the screening visit.
• Willing to apply only a basic bland emollient once or twice-daily for at least 7 days before the baseline visit.
• Willing to comply with discontinuation of certain treatments for AD, as directed by the Investigator.
• Willing to use medically effective methods of birth control
• Females of reproductive potential must have a negative serum pregnancy test at screening and negative urine pregnancy test at Day 1..
• Willing and able to comply with clinic visits and study-related procedures

Exclusion criteria

• Pregnant or breast-feeding women
• Known hypersensitivity to ASN002 or its excipients;
• Prior treatment with SYK or JAK inhibitors for which the subject received no clinical benefit, or the subject relapsed whilst on therapy.
• Has used oral or intravenous treatments (other than biologics) that could affect atopic dermatitis less than 4 weeks prior to Day 1.
• Has received any marketed or investigational biological agent within 12 weeks or 5 half-lives (whichever is longer) prior to Day 1.
• Currently receiving a non-biological investigational product or device or has received one within 4 weeks Day 1.
• Excessive sun exposure, is planning a trip to a sunny climate, or has used tanning booths within 4 weeks prior to baseline (Day 1), or is not willing to minimize natural and artificial sunlight exposure during the study.
• Has received or plans to receive a live attenuated vaccine within 4 weeks prior to Day 1 throughout the follow up period.
• Planned major surgical procedure during the length of the patient's participation in this study
