IntroductionIntegrated safety data for lebrikizumab (LEB) treatment in moderate-to-severe atopic dermatitis (AD) has been previously published. Conjunctivitis and keratitis were identified as adverse events (AEs) of special interest in the AD ­program.


Further characterize patient-reported conjunctivitis and keratitis AEs in LEB clinical trials for AD.


Data from adult and adolescent patients were analyzed in 2 groups: a) LEB 250mg every 2 weeks (LEBQ2W, N=783) vs placebo (PBO, N=404), weeks 0-16 (PC 0-16wk) from 4 clinical trials (ADvocate1, ADvocate2, ADhere, Phase 2b study); and b) patients who received at least one dose of LEB (ALL-LEB, N=1720) from 8 clinical trials (ADvocate1, ADvocate2, ADhere, ADore, ADjoin (ongoing), ARBAN, TREBLE, Phase 2b study). Conjunctivitis and keratitis refer to cluster definitions defined by MedDRA preferred terms conjunctivitis, allergic conjunctivitis, bacterial conjunctivitis, viral conjunctivitis, giant papillary conjunctivitis; and keratitis, atopic keratoconjunctivitis, allergic keratitis, ulcerative keratitis, vernal keratoconjunctivitis, respectively. Exposure adjusted incidence rates (IR) are provided as per 100 patient-years.


In PC 0-16wk, at baseline, similar proportions of LEB (21.5%) and PBO (19.3%) patients had medical history (MH) of conjunctivitis. Of ALL-LEB, 22.2% had MH of conjunctivitis; of those with conjunctivitis or keratitis AE, 40% had MH of conjunctivitis.

In PC 0-16wk, conjunctivitis cluster was reported by 8.5% (IR:30.6) LEBQ2W vs 2.5% (IR:8.9) PBO; keratitis cluster was reported by 0.6% (IR:2.2) and 0.3% (IR:0.9) of patients, respectively. All conjunctivitis and keratitis events in PC 0-16wk were mild or moderate in severity; 5 events (3 conjunctivitis, 2 keratitis) led to treatment discontinuation (LEBQ2W) vs 1 conjunctivitis event (PBO).

ALL-LEB treatment duration ranged from 1 dose to 100 weeks. In ALL-LEB, conjunctivitis cluster was reported by 10.6% (IR:12.2), with the majority being mild or moderate (10.3%) and 0.3% severe. Keratitis was reported by 0.5% (IR:0.6), with 1 severe event of vernal keratoconjunctivitis. Conjunctivitis and keratitis events resulted in 17 (1.0%) and 3 (0.2%) treatment discontinuations, respectively. Similar proportions of adult (11.3%; 0.6%) and adolescent (8.3%; 0.3%) patients reported conjunctivitis and keratitis events. The majority were reported within first 16 weeks of treatment.

ConclusionsConjunctivitis is an AE reported by LEB-treated patients. Patients with MH of conjunctivitis may have higher risk of developing treatment-emergent conjunctivitis or keratitis. Most events were mild or moderate in severity, did not lead to treatment discontinuation, were reported within first 16 weeks of treatment, and IR did not increase with longer duration of exposure.
