The primary objective of the study is to assess the efficacy of dupilumab, compared to placebo, in adult patients with moderate-to-severe atopic dermatitis.

Condition Intervention Phase
Atopic Dermatitis (AD)
Drug: dupilumab
Drug: placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study Investigating the Efficacy, Safety, Serum Concentration and Biomarker Profile of Dupilumab Administered to Adult Patients With Moderate-to-Severe Atopic Dermatitis

Further study details as provided by Regeneron Pharmaceuticals:

Primary Outcome Measures:
  • Percent change in EASI score [ Time Frame: baseline to week 16 ] [ Designated as safety issue: No ]

    The primary endpoint is the percent change in EASI (Eczema Area and Severity Index) score from day 1 (baseline) to week 16.

    [The EASI is a measure used in clinical practice and clinical trials to assess the severity and extent of AD]

Secondary Outcome Measures:
  • Proportion of patients achieving IGA score of 0 or 1 [ Time Frame: At week 16 ] [ Designated as safety issue: No ]

    Proportion of patients achieving an IGA (Investigator's Global Assessment) of clear (score = 0) or almost clear (score = 1) at week 16

    [The IGA is a scale used in clinical studies to determine severity of AD and clinical response to treatment based on a 5-point scale ranging from 0 (clear) to 4 (severe)]

  • Proportion of patients achieving IGA score reduction >/= 2 [ Time Frame: At week 16 ] [ Designated as safety issue: No ]
    Proportion of patients achieving IGA score reduction of >/= 2 at week 16

  • Change in pruritus NRS score [ Time Frame: At week 16 ] [ Designated as safety issue: No ]

    Absolute and percent change from baseline in pruritus numerical rating scale (NRS) score at week 16

    [The Pruritus NRS is a simple assessment tool that patients will use to report the intensity of their pruritus (itch), both maximum and average intensity, during a 24-hour recall period]

  • Change in EASI score [ Time Frame: baseline to week 16 ] [ Designated as safety issue: No ]
    Absolute change in EASI score from baseline to week 16

  • Change in SCORAD score [ Time Frame: baseline to week 16 ] [ Designated as safety issue: No ]

    Absolute and percent change in SCORAD (SCORing Atopic Dermatitis) score from baseline to week 16

    [SCORAD is a tool used in clinical research and clinical practice that was developed to standardize the evaluation of the extent and severity of AD]

  • Proportion of patients achieving a 50 to 90% reduction in SCORAD score [ Time Frame: At week 16 ] [ Designated as safety issue: No ]
    Proportion of patients achieving SCORAD-50, SCORAD-75, and SCORAD-90 (50, 75, and 90% reduction from baseline in SCORAD score) at week 16

  • Absolute and percent change in POEM score [ Time Frame: baseline to week 16 ] [ Designated as safety issue: No ]

    Absolute and percent change from baseline in Patient Oriented Eczema Measure (POEM) score

    [The POEM is a 7-item questionnaire used in clinical practice and clinical trials to assess disease symptoms in children and adults]

  • Change in Global Individual Sign Score [ Time Frame: baseline to week 16 ] [ Designated as safety issue: No ]

    Changes from baseline in Global Individual Sign Score (GISS) components

    [GISS assesses individual components of the AD lesions (erythema, infiltration/papulation, excoriations, and lichenification) and rates them globally (ie, each is assessed for the whole body, not by anatomical region)]

  • Changes in GISS cumulative score [ Time Frame: baseline to week 16 ] [ Designated as safety issue: No ]
    Changes from baseline in GISS cumulative score

  • Incidence of TEAEs [ Time Frame: baseline to week 32 ] [ Designated as safety issue: No ]
    Incidence of treatment-emergent adverse events (TEAEs) from baseline through week 32 (end of study)

  • Dupilumab serum concentrations [ Time Frame: baseline to week 32 ] [ Designated as safety issue: No ]
    Dupilumab serum concentrations over time from baseline through week 32 (end of study)

Estimated Enrollment: 50
Study Start Date: December 2013
Estimated Study Completion Date: June 2015
Estimated Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Group A Drug: dupilumab

Dupilumab is an anti-interleukin 4 monoclonal antibody (Anti-IL-4R alpha mAb) that is being studied for the treatment of moderate-to-severe eczema.

[In addition to active dupilumab treatment, patients are also required to apply a topical emollient twice daily from day -7 through day 8 as background treatment.]

Other Names:
  • REGN668
  • SAR231893
Placebo Comparator: Group B Drug: placebo

Placebo is a look-alike substance with no active medication

[In addition to receiving placebo, patients are also required to apply a topical emollient twice daily from day -7 through day 8 as background treatment]
