Study summary

This is a phase 2, multi-center, randomized, placebo-controlled, double-blind, parallel-group, dose-ranging study, conducted in subjects with moderate-to-severe atopic dermatitis.

Read the detailed description

This phase 2 study is designed to explore the efficacy and safety, as well as pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity of dose-ranging AK120 compared to placebo, which will generate information regarding the selection of dosing regimens with AK120 monotherapy treatment in adult subjects with moderate-to-severe AD.

Primary Objectives:

  • To evaluate the efficacy of AK120 in the treatment of adult subjects with moderate-to-severe Atopic Dermatitis (AD).

Secondary Objectives:

  • To evaluate the safety of AK120 in the treatment of adult subjects with moderate-to-severe AD.
  • To evaluate the Pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity of AK120 in adult subjects with moderate-to-severe AD.

  1. Male or female, over the age of 18
  2. Chronic atopic dermatitis (AD) diagnosed at least 1 year.
  3. Subject with EASI score ≥16, IGA ≥ 3 (on the 0 to 4 IGA scale, in which 3 is moderate and 4 is severe), ≥ 10% body surface area (BSA) of AD involvement.
  4. Subjects with a history of an inadequate response or medically inappropriate use of topical drug treatment within 6 months.

Key Exclusion Criteria:

  1. Inadequate washout period for prior drug therapy (eg. corticosteroids, immunosuppressive/ immunomodulating, biologics, phototherapy, Chinese traditional medicine, anti-infective agents).
  2. History of exposure to active TB, and/or history or current evidence of TB infection.
  3. Positive serology results at Screening for hepatitis B, hepatitis C or HIV.
  4. Any history of vernal keratoconjunctivitis (VKC) or atopic keratoconjunctivitis (AKC) within 6 months before the baseline visit.
  5. History of clinical parasite infection, recent or planned travel to an area with endemic parasite infection within 6 months before the Screening visit
  6. Any medical or psychiatric condition, laboratory, or ECG parameter which, in the opinion of the Investigator or the Sponsor's medical monitor, would place the subject at risk, interfere with participation in the study, or interfere with the interpretation of study results.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 26, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
