Phase 2 Interventional ASLAN Pharmaceuticals · NCT05694884

This study is testing if a new treatment called eblasakimab can help adults with moderate-to-severe atopic dermatitis who have already tried dupilumab feel better.

What this trial studies

This clinical trial is a multicenter, randomized, double-blind, placebo-controlled study aimed at assessing the efficacy and safety of eblasakimab in adults with moderate-to-severe atopic dermatitis who have previously been treated with dupilumab. Participants will be randomly assigned to receive either eblasakimab or a placebo over a 16-week treatment period, followed by an 8-week follow-up. The study will evaluate various clinical outcomes, including the severity of atopic dermatitis and patient-reported symptoms.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with a history of moderate-to-severe atopic dermatitis who have previously been treated with dupilumab.

Not a fit: Patients who have not previously been treated with dupilumab or those with mild atopic dermatitis may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with moderate-to-severe atopic dermatitis who have not responded adequately to dupilumab.

How similar studies have performed: Other studies have shown promise in targeting IL-13 pathways for atopic dermatitis, suggesting that this approach may be effective.

* All participants must have previously been treated with dupilumab meeting one of the following conditions:

  1. Participants who stopped dupilumab treatment due to non-response, partial response, loss of efficacy must have been previously treated with dupilumab for at least 16 weeks duration;
  2. Participants who stopped dupilumab treatment due to intolerance or adverse events (AEs) to the drug may enter the study with no required prior length of dupilumab treatment;
  3. Participants who stopped dupilumab treatment due to cost or loss of access to dupilumab or for any other reasons may enter the study with no required prior length of dupilumab treatment;

Exclusion Criteria:

* Use of immunosuppressive/immunomodulating drugs and/or therapies, JAK inhibitors, or phototherapy (including tanning booth/parlor) within 4 weeks prior to the Baseline visit
* Have an uncontrolled chronic disease that may require multiple intermittent use of systemic corticosteroids at Screening, as defined by the Investigator
* Have uncontrolled asthma that might require bursts of oral or systemic corticosteroids, or require either of the following due to ≥1 exacerbations within 12 months before Baseline:

  1. Systemic (oral and/or parenteral) corticosteroid treatment;
  2. Hospitalization for \>24 hours;
* Have had systemic treatment with small molecule investigational drugs within 8 weeks or 5 half-lives (if known), whichever is longer, prior to the Baseline visit
* Have received treatment with topical corticosteroids (TCS), topical calcineurin inhibitors (TCI) such as tacrolimus and pimecrolimus, topical phosphodiesterase inhibitors such as crisaborole, topical JAK inhibitors (commercial or investigational use), within 1 week prior to randomization
* Have inadequate organ function or abnormal lab results considered clinically significant by the Investigator at the Screening visit
* History of human immunodeficiency virus (HIV) or positive HIV serology at Screening
* Infected with hepatitis B or hepatitis C viruses. For Hepatitis B, all subjects will undergo testing for Hepatitis B Surface Antigen (HBsAg) and Hepatitis B Core Antibody (HBcAb) during Screening. Subjects who are HBsAg positive are not eligible for the study. Subjects who are HBsAg negative and HBcAb positive will be tested for Hepatitis B Surface Antibody (HBsAb) and if HBsAb is positive, may be enrolled in the study; if HBsAb is negative, the subject is not eligible for the study. For Hepatitis C, all subjects will undergo testing for Hepatitis C antibody (HCVAb) during Screening. Subjects who are HCVAb positive are not eligible for the study. Active COVID-19 infection at Baseline.
* Have known liver cirrhosis and/or chronic hepatitis of any etiology
* Known diagnosis of active tuberculosis or non-tuberculous mycobacterial infection or latent tuberculosis unless it is well documented by a specialist that the patient has been adequately treated
* Allergen immunotherapy should be discontinued 6 months before randomization
