A Study to Evaluate the Efficacy and Safety of Dupilumab in Adult and Adolescent Patients With Moderate-to-Severe Atopic Hand and Foot Dermatitis (Liberty-AD-HAFT)

The primary objective of the study is to assess the efficacy of dupilumab on skin lesions in patients with atopic hand and foot dermatitis.

The secondary objectives of the study are:

* To assess the efficacy of dupilumab on various other domains (pruritus, pain, sleep loss, health related QoL, work life impairment) in patients with atopic hand and foot dermatitis * To evaluate the safety and tolerability of dupilumab administered to patients with atopic hand and foot dermatitis * To evaluate systemic exposure and immunogenicity of dupilumab in patients with atopic hand and foot dermatitis

Primary outcomes

  1. Percentage of Participants With Hand and Foot Investigator Global Assessment (IGA) 0 or 1 at Week 16

    Time frame: At week 16

    IGA is an assessment scale used to determine severity of hand and foot 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. Higher score is indicative of more severe disease.

Secondary outcomes

  1. Percentage of Participants With Improvement (Reduction) of Weekly Average of Daily Hand and Foot Peak Pruritus Numerical Rating Scale (NRS) of ≥4 Points From Baseline to Week 16

    Time frame: Baseline to week 16

    Pruritus NRS is an assessment tool that is used to report the intensity of a patient's pruritus (itch), both maximum and average intensity, during a 24-hour recall period; maximum itch intensity on a scale of 0 - 10 (0 = no itch; 10 = worst itch imaginable).

  2. Percentage of Participants With Improvement (Reduction) of Weekly Average of Daily Hand and Foot Peak Pruritus NRS ≥3 From Baseline to Week 16

    Time frame: Baseline to week 16

    Pruritus NRS is an assessment tool that is used to report the intensity of a patient's pruritus (itch), both maximum and average intensity, during a 24-hour recall period; maximum itch intensity on a scale of 0 - 10 (0 = no itch; 10 = worst itch imaginable).

  3. Percent Change From Baseline to Week 16 in Weekly Average of Daily Hand and Foot Peak Pruritus NRS

    Time frame: Baseline to week 16

    Pruritus NRS is an assessment tool that is used to report the intensity of a patient's pruritus (itch), both maximum and average intensity, during a 24-hour recall period; maximum itch intensity on a scale of 0 - 10 (0 = no itch; 10 = worst itch imaginable).

  4. Percent Change in Modified Total Lesion Sign Score (mTLSS) for Hand/Foot Lesions From Baseline to Week 16

    Time frame: Baseline to Week 16

    mTLSS combines an evaluation of hand and foot eczema lesions severity; scores are summed, extending from a base estimation of 0 (no signs or symptoms) to the most extreme of 18 (more serious disease).

  5. Change From Baseline to Week 16 in Weekly Average of Daily Hand and Foot Peak Pain NRS

    Time frame: Baseline to week 16

    Pain NRS Scale is an assessment tool used to report the intensity of a participant's pain. Participants will select the number between 0 and 10 that fits best to their worst pain intensity over the past 24 hours (0 = no pain and 10 = the worst pain possible).

  6. Mean Change From Baseline to Week 16 in Weekly Average of Daily Sleep NRS

    Time frame: Baseline to week 16

    Sleep NRS is an 11-point scale (0 to 10) in which 0 indicates worst possible sleep while 10 indicates best possible sleep.

  7. Change From Baseline to Week 16 in Percent Surface Area of Hand and Foot Involvement With Atopic Dermatitis (AD)

    Time frame: Baseline to week 16

  8. Percent Change From Baseline to Week 4 in Weekly Average of Daily Hand and Foot Peak Pruritus NRS

    Time frame: Baseline to week 4

    Pruritus NRS is an assessment tool that is used to report the intensity of a participant's pruritus (itch), both maximum and average intensity, during a 24-hour recall period; maximum itch intensity on a scale of 0 - 10 (0 = no itch; 10 = worst itch imaginable).

  9. Percentage of Participants With Improvement (Reduction) of Weekly Average of Daily Hand and Foot Peak Pruritus NRS ≥4 From Baseline to Week 4

    Time frame: Baseline to week 4

    Pruritus NRS is an assessment tool that is used to report the intensity of a participant's pruritus (itch), both maximum and average intensity, during a 24-hour recall period; maximum itch intensity on a scale of 0 - 10 (0 = no itch; 10 = worst itch imaginable).

  10. Percent Change From Baseline to Week 16 in Hand Eczema Severity Index (HECSI) Score in Participants With Hand Dermatitis

    Time frame: Baseline to week 16

    For participants with hand dermatitis HECSI is an instrument used in clinical trials to rate the severity of 6 clinical signs of hand eczema and the extent of the lesions on each of 5 hand areas by use of standard scales. The total HECSI score is based on a 4-point severity scale ranging from 0 (none/absent) to 3 (severe) and a 5-point scale rating the affected area(s) ranging from 0 (0% affected area) to 4 (76% to 100% affected area). The range for the combined HECSI score is from 0 to 360 (5x6x3x4).

    Time frame: At week 16

    HECSI-75 is defined as HECSI score has ≥75% improvement from baseline for participants with hand dermatitis.

  12. Percentage of Participants With HECSI-50 at Week 16

    Time frame: At week 16

    HECSI-50 is defined as HECSI score has ≥50% improvement from baseline, for participants with hand dermatitis.

  13. Percentage of Participants With HECSI-90 at Week 16

    Time frame: At week 16

    HECSI-90 is defined as HECSI score has ≥90% improvement from baseline for participants with hand dermatitis.

  14. Change From Baseline to Week 16 in Quality of Life in Hand Eczema Questionnaire (QOLHEQ)

    Time frame: Baseline to week 16

    For participants with hand dermatitis, QOLHEQ is an instrument to assess disease specific Health Related Quality of Life (HRQOL) in those suffering from hand eczema. QOLHEQ overall scoring ranges as follows: 0 (best score) to 117 (worst score).

  15. Mean Change From Baseline to Week 16 in Work Productivity and Impairment (WPAI) and Classroom Impairment Questionnaire (CIQ)

    Time frame: Baseline to week 16

    WPAI + CIQ is a self-administered instrument used to capture the impairment to work productivity/classroom impairment and activity due to atopic hand and foot dermatitis. The WPAI+CIQ yields 4 types of scores: absenteeism, presenteeism, work/classroom productivity loss and activity impairment. All scores range from 0 to 100% with 100% indicating total work/classroom productivity impairment and 0 no impairment at all.
