Conditions

Atopic Hand and Foot Dermatitis

Brief summary

The main purpose of this study is to assess the efficacy of lebrikizumab versus placebo on skin lesions in adults and adolescent participants with atopic hand and foot dermatitis. This study lasts up to 32 weeks, including a 6-week screening period, a 16-week treatment period, and a safety follow-up visit 12 weeks after the last dose.

Inclusion criteria

* Have an unequivocal diagnosis of chronic atopic hand and/or foot dermatitis at least 1 year prior to screening, regardless of the extent and severity of concomitant atopic dermatitis (AD) on other areas of the body. AD must be present in at least 2 of the 4 mentioned anatomical areas: left hand, right hand, left foot, or right foot at screening and baseline. * Have a Hand Foot - Investigator Global Assessment (HF-IGA) score of 3 or 4 at the screening and baseline visits. * Have a baseline hand and foot peak pruritus (numeric rating scale) NRS score ≥4. * Have a documented history by the investigator of inadequate response to topical medication(s) (topical corticosteroids (TCIs/TCS), topical PDE-4 inhibitors, or topical janus kinase (JAK) inhibitors) in the treatment of atopic hand foot dermatitis (AHFD) within 6 months of screening, or use of topical medications is medically inadvisable (due to intolerance to treatment, hypersensitivity reactions, significant skin atrophy of hand and feet, and systemic effects, as assessed by the investigator or by the treating physician of the participant). * For adolescent participants, body weight ≥40 kilograms (kg) at baseline.

Exclusion criteria

* Have a positive patch test reaction to 1 or more allergens (a score of 1+ or above according to the International Contact Dermatitis Research Group grading scale) before baseline AND which are deemed to be clinically relevant in the view of the investigator as the current cause of the hand and foot dermatitis. * Have a documented diagnosis of allergic contact dermatitis (ACD) of hands and/or feet, and have a positive patch test reaction at screening, regardless of whether the history of current skin exposure to products containing this allergen (current relevance) is present. * Have a documented or strong clinical suspicion of the diagnosis of protein contact dermatitis of hands and/or feet. These are the participants with occupational or nonoccupational contact with proteins such as food, latex, and so on, who have positive prick test results and present with lesions of contact urticaria or dermatitis on hands and feet. * Have a documented exposure to irritants in the occupational or non-occupational (household/recreational) setting that is believed to be a predominant cause of the current hand and foot dermatitis as per the judgment of the investigator. * Presence of skin comorbidities on hand and/or foot that may interfere with study assessments, such as (but not limited to) palmoplantar psoriasis, palmoplantar keratoderma, impetiginized eczema, lichen planus, pityriasis rubra pilaris, herpes simplex, erythema multiforme, tinea, or scabies. * Have skin comorbidities that may interfere with study assessments. * Treatment with topical medications on the hands and feet within 2 weeks before the baseline visit (except for the use of the participant's own emollients). * Prior treatment with interleukin-13 (IL-13) inhibitors such as lebrikizumab or tralokinumab. * Have received any live attenuated vaccine within less than 4 weeks of the baseline visit or intend to receive a live attenuated vaccine during the study, or within 4 weeks after receiving the last dose of study intervention.

Design outcomes

Primary

MeasureTime frameDescription
Percentage of Participants Achieving a Hand and Foot Investigator Global Assessment (HF-IGA) Score of 0 or 1 with ≥2-point Improvement from BaselineWeek 16The HF-IGA is an assessment scale used to determine the severity of hand and foot atopic dermatitis (AD) and clinical response to treatment on a 5-point scale, 0 (clear) to 4 (severe). Higher scores indicate more disease severity.

Secondary

MeasureTime frameDescription
Percentage of Participants Achieving a Hand and Foot Investigator Global Assessment (HF-IGA) Score of 0 or 1 with ≥2-point Improvement from BaselineWeek 4The HF-IGA is an assessment scale used to determine the severity of hand and foot atopic dermatitis (AD) and clinical response to treatment on a 5-point scale, 0 (clear) to 4 (severe). Higher scores indicate more disease severity.
Percentage of Participants Who Are "Satisfied" or "Very Satisfied" on Atopic Hand Dermatitis Clearance Satisfaction (AHDCS)Week 16This single-item question assesses participants' satisfaction with hand clearance at the current time. The response options are reported as the percentage of participants who selected 1 of the following: Very Satisfied, Satisfied, Neither Satisfied nor Dissatisfied, Dissatisfied, or Very Dissatisfied.
Percent Change from Baseline in Hand and Foot Peak Pain NRSBaseline, Week 16The HF-peak pain NRS Scale is an assessment tool used daily by the participants to report the intensity of pain. Participants select the number between 0 and 10 that best fits their worst pain intensity over the past 24 hours (0 = no pain and 10 = the worst pain possible).
Percentage of Participants with a HF-Peak Pruritus Numeric Rating Score (NRS) of ≥4 points at Baseline Who Achieve a ≥4-point Reduction (Improvement) from BaselineWeek 16The HF-peak pruritus NRS scale is an assessment tool used daily by the participants to rate their worst hand and feet itch intensity on a scale ranging from 0 (no itch) to 10 (worst imaginable itch).
Percentage of Participants with HF-Peak Pruritus NRS of ≥4 points at Baseline Who Achieve a ≥4-point Reduction (Improvement) from BaselineBaseline, Week 4The HF-peak pruritus NRS scale is an assessment tool used daily by the participants to rate their worst hand and feet itch intensity on a scale ranging from 0 (no itch) to 10 (worst imaginable itch).
Percent Change from Baseline in Modified Total Lesion Symptom Scale (mTLSS) for Hand and Foot LesionsBaseline, Week 16The mTLSS is an investigator-reported scale that combines the evaluation of lesion severity of hand eczema (HE) (erythema, edema, desquamation, fissures, hyperkeratosis or lichenification, and vesicles) with the intensity of pruritus or pain to assess the severity of symptoms. This composite score assigns 0 (mild) to 3 (severe) to each component, giving a maximum disease severity of 21. A separate score is assigned for hands and feet.
Percentage of Participants with Hand Dermatitis Achieving HECSI-90 ScoreWeek 16The HECSI scoring system incorporates both the extent and the intensity of the disease. The total sum called the HECSI score will be calculated, varying from 0 to a maximum severity score of 360 points.
Percent Change from Baseline in Hand Eczema Severity Index (HECSI) Score for Participants with Hand DermatitisBaseline, Week 16The HECSI scoring system incorporates both the extent and the intensity of the disease. The total sum called the HECSI score will be calculated, varying from 0 to a maximum severity score of 360 points.
Percentage of Participants with Hand Dermatitis Achieving HECSI-50 ScoreWeek 16The HECSI scoring system incorporates both the extent and the intensity of the disease. The total sum called the HECSI score will be calculated, varying from 0 to a maximum severity score of 360 points.
Percentage of Participants with Hand Dermatitis Achieving HECSI-75 ScoreWeek 16The HECSI scoring system incorporates both the extent and the intensity of the disease. The total sum called the HECSI score will be calculated, varying from 0 to a maximum severity score of 360 points.
Percentage of Participants with a HF-Peak Pain NRS of ≥4 points at Baseline Who Achieve a ≥4-point Reduction (Improvement) from BaselineWeek 16The HF-peak pain NRS Scale is an assessment tool used daily by the participants to report the intensity of pain. Participants select the number between 0 and 10 that best fits their worst pain intensity over the past 24 hours (0 = no pain and 10 = the worst pain possible).
Change from Baseline in Quality of Life in Hand Eczema Questionnaire (QOLHEQ) for Participants with Hand DermatitisBaseline, Week 16The QOLHEQ consists of 30 items that can be summarized according to 4 domains of HRQoL: impairments over the last 7 days because of (1) symptoms, (2) emotions, (3) limitations in functioning, or (4) treatment and prevention. The total QOLHEQ score ranges between 0 and 117, with higher scores indicative of a poor HE-specific HRQoL.
