Conjunctivitis in dupilumab clinical trials.

ABSTRACT: BACKGROUND:Dupilumab blocks the shared receptor component for interleukin (IL)-4 and IL-13. It is approved in the U.S.A. for patients aged ? 12 years with moderate-to-severe atopic dermatitis (AD) uncontrolled by topical prescription medicines or who cannot use topical medicines, for patients in Japan whose AD is uncontrolled with existing therapies, for patients with moderate-to-severe AD in Europe who are candidates for systemic therapy and for patients aged ? 12 years for maintenance treatment of moderate-to-severe asthma uncontrolled with their current medicines. AD trials have reported increased incidence of conjunctivitis for dupilumab vs. placebo. OBJECTIVES:To characterize further the occurrence and risk factors of conjunctivitis in dupilumab clinical trials. METHODS:We evaluated randomized placebo-controlled trials of dupilumab in AD (n = 2629), asthma (n = 2876), chronic rhinosinusitis with nasal polyps (CRSwNP) (n = 60) and eosinophilic oesophagitis (EoE) (n = 47). RESULTS:In most AD trials, dupilumab-treated patients had higher conjunctivitis incidence than placebo controls. Higher baseline AD severity and previous history of conjunctivitis were associated with increased conjunctivitis incidence. Conjunctivitis was mostly mild to moderate. Most cases recovered or resolved during the treatment period; two patients permanently discontinued dupilumab due to conjunctivitis or keratitis. Common treatments included ophthalmic corticosteroids, antibiotics, and antihistamines or mast cell stabilizers. Most cases were diagnosed by the investigators. In asthma and CRSwNP trials, the incidence of conjunctivitis was lower for both dupilumab and placebo than in AD trials; dupilumab did not increase the incidence compared with placebo. In the EoE trial, no patients had conjunctivitis. CONCLUSIONS:Conjunctivitis was more frequent with dupilumab treatment in most AD trials. In dupilumab trials in other type 2 diseases, incidence of conjunctivitis was overall very low, and was similar for dupilumab and placebo. In AD, the incidence of conjunctivitis was associated with AD severity and prior history of conjunctivitis. The aetiology and treatment of conjunctivitis in dupilumab-treated patients require further study. What's already known about this topic? Ocular disorders, including allergic conjunctivitis, are common in patients with atopic dermatitis (AD). In most dupilumab AD trials, dupilumab-treated patients had higher conjunctivitis incidence than those receiving placebo. Most cases were mild to moderate and recovered or were recovering during study treatment; study treatment discontinuation due to conjunctivitis was rare. Conjunctivitis incidence was very low and similar for dupilumab and placebo in clinical trials in asthma, chronic rhinosinusitis with nasal polyps and eosinophilic oesophagitis. What does this study add? This analysis confirms and extends the results of the individual clinical trials. Baseline disease-related factors, including AD severity, prior conjunctivitis history and certain biomarkers (thymus and activation-regulated chemokine, IgE, eosinophils), were associated with increased incidence of conjunctivitis. Patients who responded well to dupilumab had reduced incidence of conjunctivitis. Further study is needed to elucidate the aetiology and treatment of conjunctivitis in dupilumab-treated patients with AD.

Project description:BackgroundConjunctivitis is a known comorbidity of atopic dermatitis. Dupilumab clinical trials for moderate-to-severe atopic dermatitis in adults showed a higher conjunctivitis incidence for dupilumab-treated patients than placebo-treated patients, whereas trials for uncontrolled asthma reported lower rates for both dupilumab and placebo.ObjectiveThe objective of this study was to evaluate the incidence and severity of conjunctivitis in dupilumab clinical trials in adolescents with moderate-to-severe atopic dermatitis or uncontrolled asthma.MethodsWe evaluated the incidence of conjunctivitis in adolescents (aged 12 to < 18 years) in three phase III trials. Ocular events were diagnosed and treated based on patient-reported symptoms and an external eye examination by study investigators, in most cases without an ophthalmologic referral. In LIBERTY AD ADOL (16-week, randomized, placebo-controlled, double-blinded trial), adolescents with moderate-to-severe atopic dermatitis were randomized to subcutaneous placebo, dupilumab 300 mg every 4 weeks, or dupilumab every 2 weeks (200 mg, patients < 60 kg at baseline; 300 mg, ≥ 60 kg at baseline). In LIBERTY AD PED-OLE (open-label extension), pediatric patients from previous dupilumab atopic dermatitis trials received dupilumab 2 mg/kg or 4 mg/kg weekly (up to 300 mg) or 300 mg every 4 weeks. In LIBERTY ASTHMA QUEST (randomized, double-blinded, placebo-controlled trial), patients with uncontrolled moderate-to-severe asthma were randomized to 52 weeks of add-on therapy with dupilumab 200 or 300 mg every 2 weeks or matched-volume placebo.ResultsIn ADOL, more dupilumab-treated (17/165; 10.3%) than placebo-treated patients (4/85; 4.7%) reported one or more conjunctivitis event. All events were mild to moderate in severity; 12 (7.3%) dupilumab-treated and 4 (4.7%) placebo-treated patients received treatment. Most patients with conjunctivitis (dupilumab, 12/17; placebo, 4/4) recovered/resolved during the treatment period. The risk of conjunctivitis showed no relationship with dupilumab serum concentration. In PED-OLE, 12/275 adolescents (4.4%) reported one or more conjunctivitis event. Most conjunctivitis events were mild to moderate. Ten patients received treatment for conjunctivitis. Ten patients recovered/resolved during the study. In QUEST, similar low proportions of dupilumab-treated (2/68, 2.9%) and placebo-treated (1/39, 2.6%) adolescents reported one or more conjunctivitis event. All events were mild to moderate. One dupilumab-treated patient received treatment for conjunctivitis. All cases recovered/resolved during the study. No patients in these trials discontinued study treatment temporarily or permanently because of conjunctivitis. In ADOL, one case of unspecified viral keratitis (specific viral etiology not known) in the dupilumab 300-mg every 4 weeks group and one case of allergic blepharitis in the placebo group were reported; both events resolved during the treatment period, and neither led to treatment discontinuation.ConclusionsDupilumab-treated adolescents in atopic dermatitis trials had a higher incidence of conjunctivitis than placebo-treated patients, whereas overall rates of conjunctivitis among adolescents in the asthma trial were lower than in atopic dermatitis trials and were similar for dupilumab- and placebo-treated patients. Most events were mild to moderate, most recovered/resolved, and none prompted study withdrawal. These results are similar to those reported in adult trials and support a drug-disease interaction.

Project description:BackgroundPatients with moderate-to-severe atopic dermatitis (AD) have increased infection risk, including skin infections and systemic infections. Immunomodulators (e.g., anti-tumor necrosis factors, anti-interleukin [anti-IL]-23, anti-IL-17, Janus kinase inhibitors) increase risk of infections. Dupilumab (a monoclonal antibody blocking the shared receptor component for IL-4 and IL-13) is approved for inadequately controlled moderate-to-severe AD and for moderate-to-severe eosinophilic or oral corticosteroid-dependent asthma.ObjectiveThe aim was to determine the impact of dupilumab on infection rates in patients with moderate-to-severe AD.MethodsThis analysis pooled data from seven randomized, placebo-controlled dupilumab trials in adults with moderate-to-severe AD. Exposure-adjusted analyses assessed infection rates.ResultsOf 2932 patients, 1091 received placebo, 1095 dupilumab 300 mg weekly, and 746 dupilumab 300 mg every 2 weeks. Treatment groups had similar infection rates overall per 100 patient-years (placebo, 155; dupilumab weekly, 150; dupilumab every 2 weeks, 156; dupilumab combined, 152), and similar non-skin infection rates. Serious/severe infections were reduced with dupilumab (risk ratio 0.43; p < 0.05), as were bacterial and other non-herpetic skin infections (risk ratio 0.44; p < 0.001). Although herpesviral infection rates overall were slightly higher with dupilumab than placebo, clinically important herpesviral infections (eczema herpeticum, herpes zoster) were less common with dupilumab (risk ratio 0.31; p < 0.01). Systemic anti-infective medication use was lower with dupilumab.ConclusionsDupilumab is associated with reduced risk of serious/severe infections and non-herpetic skin infections and does not increase overall infection rates versus placebo in patients with moderate-to-severe AD.

Project description:IntroductionThe efficacy and safety of the once-daily topical ophthalmic solutions, alcaftadine 0.25% and olopatadine 0.2%, in preventing ocular itching associated with allergic conjunctivitis were evaluated.MethodsPooled analysis was conducted of two double-masked, multicenter, active- and placebo-controlled studies using the conjunctival allergen challenge (CAC) model of allergic conjunctivitis. Subjects were randomized 1:1:1 to receive alcaftadine 0.25%, olopatadine 0.2%, or placebo. The primary efficacy measure was subject-evaluated mean ocular itching at 3 min post-CAC and 16 h after treatment instillation. Secondary measures included ocular itching at 5 and 7 min post-CAC. Ocular itch was determined over all time points measured (3, 5, and 7 min) post-CAC and the proportion of subjects with minimal itch (itch score<1) and zero itch (itch score=0) was also assessed.ResultsA total of 284 subjects were enrolled in the two studies. At 3 min post-CAC and 16 h after treatment instillation, alcaftadine 0.25% achieved a significantly lower mean itch score compared with olopatadine 0.2% (0.50 vs. 0.87, respectively; P=0.0006). Alcaftadine demonstrated a significantly lower mean itch score over all time points compared with olopatadine (0.68 vs. 0.92, respectively; P=0.0390); both alcaftadine- and olopatadine-treated subjects achieved significantly lower overall mean ocular itching scores compared with placebo (2.10; P<0.0001 for both actives). Minimal itch over all time points was reported by 76.1% of alcaftadine-treated subjects compared with 58.1% of olopatadine-treated subjects (P=0.0121). Treatment with alcaftadine 0.25% and olopatadine 0.2% was safe and well tolerated; no serious adverse events were reported.ConclusionOnce-daily alcaftadine 0.25% ophthalmic solution demonstrated greater efficacy in prevention of ocular itching compared with olopatadine 0.2% at 3 min post-CAC (primary endpoint), and over all time points, 16 h post-treatment instillation. Alcaftadine and olopatadine both provided effective relief compared with placebo and were generally well tolerated.

Project description:BackgroundDupilumab, a human monoclonal antibody, blocks the shared receptor unit for interleukin-4 and interleukin-13. International phase II and III studies have evaluated the efficacy and safety of dupilumab in adults with moderate-to-severe atopic dermatitis (AD), but the effects of dupilumab in Japanese patients have not been reported.ObjectivesTo evaluate the efficacy and safety of dupilumab in Japanese patients with moderate-to-severe AD.MethodsWe analysed the efficacy and safety of dupilumab in the Japanese cohorts of a 16-week, phase IIb dose-finding trial (AD-1021; NCT01859988); a 16-week, phase III, placebo-controlled monotherapy trial (LIBERTY AD SOLO 1; NCT02277743) and a 52-week, phase III, placebo-controlled study of dupilumab with topical corticosteroids (LIBERTY AD CHRONOS; NCT02260986).ResultsTwenty-seven, 106 and 117 Japanese patients were enrolled in AD-1021, SOLO 1 and CHRONOS, respectively. Baseline disease severity was numerically higher in the Japanese cohort than in the overall study population. Generally, dupilumab significantly improved signs and symptoms of AD, including pruritus and patient quality of life, compared with placebo in the Japanese cohort, consistent with the overall study population. The combined safety profile of dupilumab in the Japanese cohort was similar to that in the total study populations; dupilumab was associated with an increased incidence of injection-site reactions and conjunctivitis compared with placebo. Dupilumab was associated with rapid reduction in thymus and activation-regulated chemokine and gradual IgE reductions.ConclusionsDupilumab alone or with topical corticosteroids improved signs and symptoms of AD, had an acceptable safety profile, and suppressed biomarkers of type 2 inflammation compared with placebo in Japanese adult patients with moderate-to-severe AD. What's already known about this topic? Differences in atopic dermatitis (AD) pathology have been reported between Asian and Western populations, in which distinct helper T-cell activation profiles have been observed. International clinical studies in adults with moderate-to-severe AD have evaluated the efficacy and safety of dupilumab, which blocks interleukin-4 and interleukin-13, key molecules in type 2 inflammation. The effects of dupilumab in Japanese patients specifically have not yet been reported. What does this study add? Dupilumab alone or with topical corticosteroids improved signs and symptoms of AD and had an acceptable safety profile compared with placebo in Japanese patients with moderate-to-severe AD. The effects were comparable with those observed in the overall study population. Reported immunological differences in AD pathology in Asian patients may be secondary to type 2 immune activation.

Project description:ImportanceErythrodermic atopic dermatitis (AD) is a severe AD subtype defined by extensive skin involvement, leading to complications and sometimes hospitalization.ObjectiveTo assess dupilumab's efficacy and safety in patients with erythrodermic AD in clinical trials.Design, setting, and participantsThis post hoc analysis included patients enrolled in 6 multicenter, multinational, randomized, double-blind, placebo-controlled trials. Patients included in this analysis met erythrodermic AD criteria of 90% or greater body surface area (BSA) affected by AD and Global Individual Sign Score for erythema of 1 or higher. Data analyses for this post hoc analysis were conducted between March 5, 2019, and October 24, 2020.InterventionsDupilumab once weekly or every 2 weeks, or placebo, either as monotherapy or with concomitant topical corticosteroids (TCS).Main outcomes and measuresEfficacy (BSA, Eczema Area and Severity Index [EASI] score, Peak Pruritus Numerical Rating Scale [PP-NRS] score), changes in serum biomarkers (thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase), and safety (incidence of adverse events) at week 16. Data were pooled within each regimen; monotherapy and concomitant TCS results are shown separately.ResultsOf 3075 randomized patients, 209 met criteria for erythrodermic AD at baseline, with the median age being 31 and 39 years in the monotherapy and concomitant TCS trials, respectively, similar to the overall populations (34 and 36 years, respectively); 71.3% (n = 97) and 74.0% (n = 54) of patients, respectively, were male (compared with 58.7% and 60.6% in the overall populations). In patients with erythrodermic AD, dupilumab once weekly and every 2 weeks vs placebo significantly improved percentage of BSA affected by AD (least squares mean percent change [SE]) with monotherapy (-42.0% [7.7%] and -39.9% [6.5%] vs -17.2% [11.0%]; P = .03) and concomitant TCS (-63.2% [6.7%] and -56.1% [9.1%] vs -14.5% [7.3%]; P < .001); EASI score with monotherapy (-58.5% [9.0%] and -58.3% [7.9%] vs -22.3% [12.4%]; P = .004 and P = .003, respectively) and concomitant TCS (-78.9% [7.8%] and -70.6% [10.1%] vs 19.3% [8.2%]; P < .001); and PP-NRS score in monotherapy (-45.9% [7.8%] and -33.9% [6.6%] vs -0.6% [9.4%]; P < .001) and concomitant therapy (-53.0% [8.1%] and -55.7% [10.8%] vs -26.0% [8.8%]; P = .006 and P = .01, respectively). Nominally statistically significant improvement was seen as early as week 1 (EASI and PP-NRS scores with monotherapy). Biomarker levels were significantly reduced vs placebo. The most frequent adverse events in dupilumab-treated patients were injection-site reaction, conjunctivitis, and nasopharyngitis.Conclusions and relevanceIn this post hoc analysis of 6 randomized clinical trials, treatment with dupilumab resulted in rapid, sustained improvements in AD signs and symptoms with acceptable safety in patients with erythrodermic AD, similar to those in the trials' overall patient population.Trial registrationClinicalTrials.gov Identifiers: NCT01859988, NCT02277743, NCT02277769, NCT03054428, NCT02260986, NCT02755649.
