• 1 other identifier: R668-AD-1416
• Study Type: interventional
• Target: 708
• Locations: 11 countries
• Sites: 93

Brief Summary

This is a randomized, double-blind, placebo-controlled, parallel-group study to confirm the efficacy and safety of Dupilumab monotherapy in adults with moderate-to-severe atopic dermatitis (AD).

Conditions

Dermatitis, Atopic

Outcome Measures

Primary Outcomes (1)

• Percentage of Participants With Investigator's Global Assessment (IGA) Score of "0" or "1" and Reduction From Baseline of ≥2 Points at Week 16

  IGA is an assessment scale used to determine severity of AD and clinical response to treatment on a 5-point scale (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe) based on erythema and papulation/infiltration. Therapeutic response is an IGA score of 0 (clear) or 1 (almost clear). Participants with IGA score of "0" or "1" and a reduction from baseline of ≥2 points at Week 16 were reported. Values after first rescue treatment were set to missing and participants with missing IGA scores at Week 16 were considered as non-responders.

  Week 16

Secondary Outcomes (20)

• Percentage of Participants With Eczema Area and Severity Index-75 (EASI-75) (≥75% Improvement From Baseline) at Week 16

  Week 16

• Percentage of Participants With Improvement (Reduction ≥4 Points) of Weekly Average of Peak Daily Pruritus Numerical Rating Scale (NRS) Score From Baseline to Week 16

  Baseline to Week 16

• Percentage of Participants With Improvement (Reduction ≥3 Points) in Weekly Average of Peak Daily Pruritus Numerical Rating Scale (NRS) Score From Baseline to Week 16

  Baseline to Week 16

• Percent Change From Baseline in Weekly Average of Peak Pruritus Numerical Rating Scale (NRS) Score to Week 16

  Baseline to Week 16

• Percentage of Participants With Improvement (Reduction ≥4 Points) of Pruritus Numerical Rating Scale (NRS) Score From Baseline to Week 4

• Documented recent history (within 6 months before the screening visit) of inadequate response to treatment with topical medications or for whom topical treatments are otherwise medically inadvisable (eg, because of important side effects or safety risks).

You may not qualify if:

• Participation in a prior Dupilumab clinical study.
• Treatment with an investigational drug within 8 weeks or within 5 half-lives (if known), whichever is longer, before the baseline visit;
• Having used any of the following treatments within 4 weeks before the baseline visit, or any condition that, in the opinion of the investigator, is likely to require such treatment(s) during the first 4 weeks of study treatment:
• Immunosuppressive/ immunomodulating drugs (eg, systemic corticosteroids, cyclosporine, mycophenolate-mofetil, IFN-γ, Janus kinase inhibitors, azathioprine, methotrexate, etc.)
• Phototherapy for AD
• Regular use (more than 2 visits per week) of a tanning booth/ parlor within 4 weeks of the screening visit;
• Treatment with a live (attenuated) vaccine within 12 weeks before the baseline visit;
• History of human immunodeficiency virus (HIV) infection or positive HIV serology at screening;
• Positive with hepatitis B surface antigen (HBsAg) or hepatitis C antibody at the screening visit;
• Active chronic or acute infection requiring systemic treatment within 2 weeks before the baseline visit;
