Phase 4

Not yet recruiting

• Conditions: Atopic Dermatitis
• Interventions: Drug: lebrikizumab

• Registration Number: NCT06906497
• Lead Sponsor: Johann E Gudjonsson MD PhD

Brief Summary

This research is studying a drug already approved for the treatment of atopic dermatitis (AD). This research collects health-related information and blood and skin samples to understand if the study drug, lebrikizumab, leads to long-term improvement in AD skin.

Detailed Description

Lebrikizumab, the drug used in the study, has been deemed IND exempt by the FDA.

Recruitment & Eligibility

• Status: NOT_YET_RECRUITING
• Sex: All
• Target Recruitment: 48

Inclusion Criteria

• Established diagnosis of AD for at least 1 year before the screening visit and topical treatment was inadequate or inadvisable.
• Moderate-to-severe AD with involvement > 10% of body-surface-area (BSA) and investigator global assessment (IGA) score =3 (based on the IGA scale ranging from 0 to 4, in which 3 is moderate and 4 is severe) at both the screening and baseline visits.
• Subject has an Eczema Area and Severity Index (EASI) score =16 at screening and baseline.
• Subject has a pruritus NRS =4.
• Subject is biologic naïve.
• Female subjects of childbearing potential (i.e., fertile, following menarche and until becoming post-menopausal unless permanently sterile) must agree either to commit to true abstinence throughout the study and for at least 17 weeks after the last study drug (SD) injection, when this is in line with the preferred and usual lifestyle of the subject, or to use a highly-effective and approved method of contraception throughout the study and for at least 17 weeks after the last study drug injection.
• Subject willing and able to comply with all of the clinical study protocol's time commitments and procedural requirements.
• Understand and sign an informed consent form (ICF) (and assent form, when applicable) before any investigational procedure(s) are performed.

Exclusion Criteria

• Previous treatment with lebrikizumab or participation in a lebrikizumab study.

• History of anaphylaxis as defined by the Sampson criteria.

• Treatment with topical corticosteroids, calcineurin inhibitors, Jak inhibitors, or crisaborole within 1 week prior to the baseline visit.

• Prior treatment with dupilumab or tralokinumab.

• Treatment with any of the following agents within 4 weeks prior to the baseline visit:

  1. Immunosuppressive/immunomodulating drugs (e.g., systemic corticosteroids, cyclosporine, mycophenolate-mofetil, IFN-., Janus kinase inhibitors (JAKi), azathioprine, methotrexate).
  2. Phototherapy and photochemotherapy (PUVA) for AD.

• Treatment with the following prior to the baseline visit:

  1. An investigational drug within 8 weeks or 5 half-lives (if known), whichever is longer.
  2. Cell-depleting biologics, including to rituximab, within 6 months.
  3. Other biologics within 5 half-lives (if known) or 16 weeks, whichever is longer.

• Use of prescription moisturizers within 7 days of the baseline visit.

• 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 of the baseline visit or planned during the study.

• Uncontrolled chronic disease that might require bursts of oral corticosteroids, e.g., co-morbid severe uncontrolled asthma requiring systemic [oral and/or parenteral] corticosteroid treatment or hospitalization for > 24 hours).

• Active chronic or acute infection requiring treatment with systemic antibiotics, antivirals, anti-parasitics, antiprotozoals, or antifungals within 2 weeks before the baseline visit, or superficial skin infections within 1 week before the baseline visit. NOTE: patients may be rescreened after infection resolves.

• Evidence of active acute or chronic hepatitis (as defined by the Department of Health & Human Services Centers for Disease Control and Prevention) or known liver cirrhosis.

• Diagnosed active endoparasitic infections or at high risk of these infections.

• Known or suspected history of immunosuppression, including history of invasive opportunistic infections (e.g., tuberculosis [TB], histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, and aspergillosis) despite infection resolution: or unusually frequent, recurrent, or prolonged infections, per the Investigator's judgment.

• History of human immunodeficiency virus (HIV) infection or positive HIV serology at screening.

• In the Investigator's opinion, any clinically significant laboratory results from the chemistry, hematology or urinalysis tests available in the medical history.

• Presence of skin comorbidities that may interfere with study assessments.

• History of malignancy, including mycosis fungoides, within 5 years before the screening visit, except completely treated in situ carcinoma of the cervix, completely treated and resolved non-metastatic squamous or basal cell carcinoma of the skin.

• Severe concomitant illness(es) that in the Investigator's judgment would adversely affect the patient's participation in the study. Any other medical or psychological condition that in the opinion of the Investigator may suggest a new and/or insufficiently understood disease, may present an unreasonable risk to the study patient because of his/her participation in this clinical trial, may make patient's participation unreliable, or may interfere with study assessments.

  20. Pregnant or breastfeeding women, or women planning to become pregnant or breastfeed during the study.

Arm && Interventions

Group	Intervention	Description
Moderate-to-severe Atopic Dermatitis	lebrikizumab	A total of 48 subjects with active moderate-to-severe Atopic Dermatitis (AD) will be enrolled in a 60-week study from 4 independent sites (2 US sites and 2 EU sites).

Primary Outcome Measures

Name	Time	Method
Degree of normalization of transcriptomic/epigenetic profile	Up to week 60	Assessed from skin biopsies using the molecular response to lebrikizumab among patients with atopic dermatitis

Secondary Outcome Measures

Name	Time	Method
Molecular response to Lebrikizumab	weeks 36 to 60	Assessed from skin biopsies using the molecular response to lebrikizumab among patients with atopic dermatitis, analyzed for those who discontinued treatment as well as those who continued it
Skin barrier function	Up to week 60	Assessed by serial transepidermal water loss (TEWL) measurements in lesional skin. TEWL will be measured using Courage + Khazaka gmbh tewameter hex for spot measurements
Clinical response as assessed be the Eczema Area and Severity Index (EASI)	Up to week 60	Clinical response assessed using the EASI - Total score ranges from 0 (minimum) to 72 (maximum), higher scores indicating greater severity of AD to be correlated with Molecular response, assessed using single-cell RNA-sequencing; This will be done using correlation based analyses and with correction for multiple testing (FDR).
Clinical response as assessed using the investigator global assessment (IGA)	Up to week 60	Clinical response assessed using the IGA - Score ranges from '0' = Clear to '5' = Very Severe Disease to be correlated with molecular response, assessed using single-cell RNA-sequencing.; This will be done using correlation based analyses and with correction for multiple testing (FDR).
Clinical response as assessed using the Peak Pruritus Numerical Rating Scale (NRS) (Pruitis NRS)	Up to week 60	Clinical response assessed using the Pruitis NRS - is a single self-report item on an 11-point scale (0 to10) where 0 is No itch, and 10 is the Worst itch imaginable. That will be correlated with the molecular response, assessed using single-cell RNA-sequencing; This will be done using correlation based analyses and with correction for multiple testing (FDR).
