Phase 3
Recruiting
Conditions
Lichen Simplex Chronicus
Interventions
Drug: Placebo
Registration Number
NCT06687967
Lead Sponsor
Sanofi
Brief Summary

This is a parallel, Phase 3, 2-arm study for treatment. The purpose of this study is to measure improvement in pruritus with dupilumab subcutaneous injections compared with placebo injections in male and female participants aged at least 18 years with LSC.

Study details include:

The study duration will be up to 40 weeks. The treatment duration will be up to 24 weeks. The follow-up duration after treatment will be 12 weeks. The number of visits will be 6.

Inclusion Criteria

Participants are eligible to be included in the study only if all of the following criteria apply (at screening and baseline unless otherwise specified):

  • Participant must be at least 18 years of age or the legal age of consent in the jurisdiction in which the study is taking place at the time of signing the informed consent.

  • Participants with moderate-to-severe LSC, as defined by Investigator's Global Assessment (IGA) score ≥3 and one or more of the following:

    • at least 1 single anogenital lesion;
    • at least 2 lesions including 1 lesion of ≥3 cm in diameter;
    • at least 1 severe lesion (IGA score = 4).
  • History of LSC for at least 6 months prior to the screening visit.

  • On the Worst-Itch Numerical Rating Scale (WI-NRS) ranging from 0 to 10, participants must have an average worst-itch of LSC score of ≥7 in the 7 days prior to Day 1. A minimum of 4 daily scores out of the 7 days is required to calculate the baseline average score. For participants who do not have at least 4 daily scores reported during the 7 days immediately preceding the planned randomization date, randomization can be postponed until this requirement is met, but without exceeding the 28-day maximum duration of the screening period.

  • History of failing a 2-week course of medium-to-superpotent topical corticosteroid (TCS) +/- topical calcineurin inhibitor (TCI) for the treatment of LSC within the last 6 months, unless TCS/TCI are medically not advisable. Patients with documented systemic treatment for LSC (other than antihistamines) in the past 6 months are also considered as inadequate responders to topical treatments and are potentially eligible for treatment with dupilumab after appropriate washout.

  • Appropriate contraceptive measures

Exclusion Criteria

Participants are excluded from the study if any of the following criteria apply (at screening and baseline unless otherwise specified):

  • Participants diagnosed with active lesions of prurigo nodularis (broadly distributed nodules) or active lesions of atopic dermatitis (AD) within 6 months, contact dermatitis, psoriasis, cutaneous T-cell lymphoma (CTCL) XE "CTCL" \f Abbreviation \t "cutaneous T-cell lymphoma" (or suspected of CTCL), vulvar lichen planus, or vulvar lichen sclerosus.
  • Presence of skin morbidities other than LSC that, in the opinion of the Investigator, may interfere with the assessment of the study outcomes. For example: scabies, insect bite, folliculitis, lymphomatoid papulosis, chronic actinic dermatitis, dermatitis herpetiformis, sporotrichosis, bullous disease, lichen planus hypertrophicus.
  • Severe concomitant illness(es) that, in the Investigator's judgment, would adversely affect the participant's participation in the study.
  • Severe psychiatric disease that, in the Investigator's judgement, would affect the study intervention evaluation.
  • Having received or planning to use any of the treatments within the timeframe as specified in the protocol.

Primary Outcome Measures
NameTimeMethod
Proportion of participants with improvement (reduction) in weekly average of daily WI-NRS by ≥4 from baseline to Week 24Week 24

Worst-Itch numerical rating score (WI-NRS) is a patient report outcome (PRO) comprised of a single item rated on a scale from 0 ("No itch") to 10 ("Worst imaginable itch").

Secondary Outcome Measures
NameTimeMethod
Change in weekly average of daily WI-NRS from baseline to Week 24Baseline to Week 24

WI-NRS is a PRO comprised of a single item rated on a scale from 0 ("No itch") to 10 ("Worst imaginable itch").

Change in weekly average of daily Itch-related Sleep Disturbance NRS from baseline to Week 24Baseline to Week 24

The Itch-related Sleep Disturbance NRS is a single-item PRO to report the degree of sleep loss related to itch over the past 24 hours, from 0 ("no sleep loss related to itch") to 10 ("I cannot sleep at all due to itch").

Change in ItchyQoL score from baseline to Week 24Baseline to Week 24

Itchy quality of life survey (ItchyQoL) is a pruritus-specific QoL instrument to measure dermatology-specific QoL in patients aged 16 years and older. The overall score ranging from 1 to 5. A higher score corresponds to a more adverse impact on health-related QoL

Change in DLQI total score from baseline to Week 24Baseline to Week 24

Dermatology life quality index (DLQI) is a validated 10-item questionnaire to measure dermatology-specific quality of life (QoL) in adult patients. Overall scoring ranges from 0 to 30, with a higher score indicating a poorer health-related QoL.

Proportion of participants with improvement (reduction) in weekly average of daily WI-NRS by ≥4 from baseline to Week 12Week 12

WI-NRS is a PRO comprised of a single item rated on a scale from 0 ("No itch") to 10 ("Worst imaginable itch").
