Category Scores
Accurate Statements
Ebglyss (lebrikizumab-lbkz) is an FDA-approved biologic injection for adults with moderate-to-severe atopic dermatitis.
1 INDICATIONS AND USAGE
Ebglyss targets interleukin-13 (IL-13).
11 DESCRIPTION; 12.1 Mechanism of Action
Phase 3 trials showed reduced itching with Ebglyss compared to placebo.
14.1 Atopic Dermatitis (itch severity via reduction on Pruritus NRS; Table 3)
Ebglyss is administered as a 250 mg subcutaneous injection every two weeks after initial loading doses.
2.2 Recommended Dosage; 14.1 Atopic Dermatitis
Ebglyss is for patients whose eczema does not respond well to topical therapies.
1 INDICATIONS AND USAGE (disease not adequately controlled with topical prescription therapies)
In ADvocate1 and ADvocate2 trials, 43% of patients achieved clear/almost clear skin (IGA 0/1) with Ebglyss versus 13% with placebo at week 16.
14.1 Atopic Dermatitis; Table 3
Long-term data through week 52 sustained the results.
14.1 Atopic Dermatitis (maintenance/durability through Week 52)
Unsupported Statements
Atopic dermatitis is the medical term for eczema.
Not supported by the provided label text.
IL-13 is described as driving skin inflammation, itch, and barrier dysfunction in eczema.
Label supports IL-13 involvement in atopic dermatitis pathogenesis/type 2 inflammation, but the specific phrasing about itch and barrier dysfunction is not explicitly supported in the provided sections.
Eli Lilly received approval for Ebglyss in September 2024.
Not present in provided label sections.
Phase 3 trials showed significant clearance of skin lesions with Ebglyss compared to placebo.
Label supports IGA 0/1 outcomes with ≥2-point improvement vs placebo, but does not explicitly use the term 'clearance of skin lesions'.
After initial loading doses, Ebglyss maintenance is every four weeks for responders.
Label provides maintenance options (250 mg every four weeks or every eight weeks) but does not state 'for responders' in the provided dosing wording.
Ebglyss is described as an alternative to Dupixent with potentially fewer injections long-term.
Not supported by the provided label text.
Dupixent (dupilumab) is an IL-4/IL-13 blocker.
Not supported by the provided label text for Ebglyss.
Ebglyss is for patients aged 12+ (pending pediatric approval) with eczema covering at least 10% body surface area, failing topicals.
Label includes age 12+ with weight ≥40 kg and BSA involvement ≥10% and not adequately controlled with topical prescription therapies, but 'pending pediatric approval' is not supported.
In ADvocate1 and ADvocate2 trials, 33% achieved itch-free nights with Ebglyss versus 11% with placebo.
Label provides itch severity improvements on Pruritus NRS but does not support the specific 'itch-free nights' endpoint.
Common eye inflammation adverse effects with Ebglyss include conjunctivitis (7–11%).
Provided label excerpts do not include incidence rates such as 7–11% for conjunctivitis.
Common herpes infection adverse effects with Ebglyss occur at a rate of 3–5%.
Provided label excerpts do not mention herpes infection or any 3–5% rate.
Injection site reactions occur at a rate of 2–3% with Ebglyss.
Provided label excerpts do not include injection site reaction rates.
Ebglyss has no black-box warnings.
Not supported by the provided label text.
Monitoring for hypersensitivity is recommended for Ebglyss.
Label section describes discontinuation and appropriate therapy for serious hypersensitivity, but does not explicitly recommend a 'monitoring' practice in the provided text.
Ebglyss has a list price of about $7,000/month.
Not supported by the provided label text.
Lilly's copay cards cap out-of-pocket at $0–25 for eligible insured patients via Lilly's program.

Important Omissions
Boxed warning status cannot be verified from provided label sections; contraindications and complete boxed warning/pregnancy-lactation content were not included in the provided excerpts.
Importance:
High
Safety Assessment
Potential Patient Risk:
Medium
Several safety-related claims include specific incidence-rate assertions (conjunctivitis, herpes infections, injection site reactions) that are not supported by the provided label text, which could mislead interpretation of risk. Additionally, hypersensitivity guidance was inaccurately reframed as 'monitoring'. The provided excerpts also do not include complete boxed warning/contraindication/pregnancy-lactation sections, limiting safety-critical verification.

Primary Issue
Multiple claims are not supported by the provided FDA label text, especially safety incidence-rate statements and several dosing/eligibility nuances.
Suggested Improvement
Restrict claims to specific supported label statements from the provided sections (e.g., indications, dosing schedule, IGA/pruritus endpoints, and described precautions). Remove or qualify all incidence-rate, unrelated market/payer/pricing/patent assertions, and avoid unsupported endpoint wording (e.g., 'itch-free nights').
