New biologic drug aims to clear stubborn eczema in just 24 weeks
NCT ID NCT05990725
First seen Jul 17, 2026 · Last updated Jul 17, 2026
Summary
This study tests whether lebrikizumab, an injectable biologic, can improve skin symptoms in adults and adolescents (aged 12 and older) with moderate-to-severe atopic dermatitis, also known as eczema. Participants receive lebrikizumab for 24 weeks, and doctors measure changes in eczema severity using a standard skin score. The goal is to see if this treatment can reduce redness, thickening, and itching enough to make a real difference in daily life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lebrikizumab, an injectable biologic drug
- What this could lead to
- If successful, lebrikizumab could offer a new treatment option for people with moderate-to-severe eczema, helping to clear skin and reduce itching.
- What could go wrong
- This is an open-label study without a placebo group, so results may be less reliable. Side effects from lebrikizumab are possible, and it may not work for everyone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults and adolescents (aged \>=12 to less than \[\<\] 18 years at the time of informed consent form (ICF)/informed assent form (IAF) signature and weighing \>=40 kg) who are candidates for systemic AD therapy. * Chronic AD that has been present for \>=1 year before the Screening visit. * EASI score \>=12 at the Day 1/Baseline Visit. * IGA score \>=3 (moderate) (scale of 0 \[clear\] to 4 \[severe\]) at the Baseline visit. * \>=10% BSA of AD involvement at the Day 1/Baseline visit. * History of inadequate response to treatment with topical medications; or determination that topical treatments are otherwise medically inadvisable. * Completed electronic diary (eDiary) entries for pruritus and sleep-loss for a minimum of 4 of 7 days before Day 1/Baseline. * Willing and able to comply with all clinic visits and study-related procedures and questionnaires. * For women of childbearing potential: agree to remain abstinent (refrain from heterosexual intercourse) or to use a highly effective contraceptive method during the treatment period and for at least 4 weeks or 1 menstrual period after the last dose of lebrikizumab. * Participant must provide signed ICF. Adolescent participants must also provide separate informed assent to enroll in the study and sign and date either a separate IAF or the ICF signed by the parent/legal guardian (as appropriate based on local regulations and requirements). Exclusion Criteria: * Prior treatment at any time with tralokinumab, lebrikizumab, or an oral JAK inhibitor. * Intention to use any concomitant medication or therapy that is not permitted by this protocol or failure to undergo the required washout period for a particular prohibited medication. * History of anaphylaxis as defined by the Sampson criteria. * Uncontrolled chronic disease that might require bursts of oral corticosteroids, example, co-morbid severe uncontrolled asthma (defined by an Asthma Control Questionnaire-5 score \>=1.5 or a history of \>=2 asthma exacerbations within the last 12 months requiring systemic \[oral and/or parenteral\] corticosteroid treatment or hospitalisation for \>24 hours). * Occurrence of the following types of infection within 3 months of Screening or develop any of these infections before Day 1/Baseline: 1. Serious (requiring hospitalisation, and/or IV or equivalent oral antibiotic treatment, as per the Investigator's opinion); 2. Opportunistic 3. Chronic (duration of symptoms, signs, and/or treatment of 6 weeks or longer); 4. Recurring (including, but not limited to herpes simplex, herpes zoster, recurring cellulitis, chronic osteomyelitis). * Known current or chronic infection with hepatitis B virus. * Known liver cirrhosis and/or chronic hepatitis of any aetiology. * Known active endoparasitic infections or at high risk of these infections. * Known or suspected history of immunosuppression, including history of invasive opportunistic infections (example, tuberculosis, histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, and aspergillosis) despite infection resolution: or unusually frequent, recurrent, or prolonged infections, per the Investigator's judgement. * History of human immunodeficiency virus (HIV) infection or known positive HIV serology. * Any clinically significant laboratory test results from the chemistry or haematology tests obtained at the Screening visit that would jeopardise the patient's participation in the study, per the Investigator's judgement. * 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 nonmetastatic squamous or basal cell carcinoma of the skin with no evidence of recurrence in the past 12 weeks. * Severe concomitant illness(es) that in the Investigator's judgement would adversely affect the 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 participant because of his/her participation in this clinical trial, may make participation unreliable, or may interfere with study assessments. * Pregnant or breastfeeding women, or women planning to become pregnant or breastfeed during the study.
