Efficacy and safety of topical calcineurin inhibitors for the treatment of atopic dermatitis: meta-analysis of randomized clinical trials.

ABSTRACT:

Introduction

Calcineurin inhibitors, novel topical immunomodulators, may constitute a superior alternative for glucocorticosteroids in atopic dermatitis (AD) topical treatment.

Aim

Determination of efficacy and safety of each topical calcineurin inhibitor (TCI) formulation, 0.3% or 0.1% tacrolimus and 1% pimecrolimus, for the treatment of moderate to severe AD in comparison with glucocorticosteroids.

Material and methods

Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, GREAT database, trials registers and reference lists were searched up to February 2018. Randomised controlled trials of TCI, compared to corticosteroids (TCS), reporting efficacy or safety outcomes were selected. Quality of trials and evidence of each outcome were evaluated according to Cochrane Collaboration recommendations and tools. The primary outcomes were physician's global assessment of improvement and occurrence of adverse events (AEs).

Results

Fourteen trials involving 7376 children and adults with AD were included. Calcineurin inhibitors were significantly more effective than various potency TCS, neither least potent to lower mid-strength nor mid-strength to potent TCS (RR = 1.24, 95% CI: 1.06-1.44). The major AEs were skin burning and pruritus, their incidence was higher in TCI treatment (RR = 3.32, 95% CI: 2.90-3.80; RR = 1.59, 95% CI: 1.34-1.80).

Conclusions

Calcineurin inhibitors seem to be more effective and contrarily they elicit more AEs than TCS.

Project description:ObjectiveTo determine the efficacy and tolerability of topical pimecrolimus and tacrolimus compared with other treatments for atopic dermatitis.DesignSystematic review and meta-analysis.Data sourcesElectronic searches of the Cochrane Library, Medline, and Embase.Study selectionRandomised controlled trials of topical pimecrolimus or tacrolimus reporting efficacy outcomes or tolerability.Data extractionEfficacyinvestigators' global assessment of response; patients' global assessment of response; proportions of patients with flares of atopic dermatitis; and improvements in quality of life. Tolerability: overall rates of withdrawal; withdrawal due to adverse events; and proportions of patients with burning of the skin and skin infections.Data synthesis4186 of 6897 participants in 25 randomised controlled trials received pimecrolimus or tacrolimus. Both drugs were significantly more effective than a vehicle control. Tacrolimus 0.1% was as effective as potent topical corticosteroids at three weeks and more effective than combined treatment with hydrocortisone butyrate 0.1% (potent used on trunk) plus hydrocortisone acetate 1% (weak used on face) at 12 weeks (number needed to treat (NNT) = 6). Tacrolimus 0.1% was also more effective than hydrocortisone acetate 1% (NNT = 4). In comparison, tacrolimus 0.03% was more effective than hydrocortisone acetate 1% (NNT = 5) but less effective than hydrocortisone butyrate 0.1% (NNT = -8). Direct comparisons of tacrolimus 0.03% and tacrolimus 0.1% consistently favoured the higher strength formulation, but efficacy differed significantly between the two strengths only after 12 weeks' treatment (rate ratio 0.80, 95% confidence interval 0.65 to 0.99). Pimecrolimus was far less effective than betamethasone valerate 0.1% (NNT = -3 at three weeks). Pimecrolimus and tacrolimus caused significantly more skin burning than topical corticosteroids. Rates of skin infections in any of the comparisons did not differ.ConclusionsBoth topical pimecrolimus and topical tacrolimus are more effective than placebo treatments for atopic dermatitis, but in the absence of studies that show long term safety gains, any advantage over topical corticosteroids is unclear. Topical tacrolimus is similar to potent topical corticosteroids and may have a place for long term use in patients with resistant atopic dermatitis on sites where side effects from topical corticosteroids might develop quickly. In the absence of key comparisons with mild corticosteroids, the clinical need for topical pimecrolimus is unclear. The usefulness of either treatment in patients who have failed to respond adequately to topical corticosteroids is also unclear.

Project description:ObjectiveEvaluate the safety profile and tolerability of topical phosphodiesterase 4 (PDE4) inhibitors versus vehicle as treatment for atopic dermatitis in published studies.MethodsA search was performed in Medline/PubMed, Web of Science, and Cochrane Library databases on September 27, 2021, by 1 evaluator, without restrictions on publication dates or languages. Terms such as atopic dermatitis, phosphodiesterase 4 inhibitors, calcineurin inhibitors, and randomized controlled trials were included. The database searches were carried out by 1 evaluator. The titles and abstracts were reviewed for the identification and evaluation of potentially eligible studies. Study selection was made by two reviewers, so there was no intra-examiner statistic at the study selection step. The full-text articles were reviewed to determine whether or not they would be included in the systematic review. Global analyses, which included studies with both unclear and low risk of bias and subanalyses of studies with a low risk of bias were performed.ResultsOut of 237 identified articles, 14 clinical trials were included in the meta-analysis. In global analyses of studies with low and unclear risk of bias, topical treatment with PDE4 inhibitors did not differ from vehicle treatment in global treatment emergent adverse events (relative risk = 0.99; 95% CI, 0.87-1.14; P = 0.94) or in serious emergent adverse events appearance (relative risk = 0.92; 95% CI, 0.39-2.20; P = 0.86). In subanalyses of studies with a low risk of bias, a reduced rate of atopic dermatitis exacerbation was observed in PDE4 inhibitors compared with the vehicle (relative risk = 0.62; 95% CI, 0.39-0.98; P = 0.04) and risk of pain at the application site was confirmed (relative risk = 2.59; 95% CI, 1.27-5.28; P = 0.01).ConclusionsPDE4 inhibitors did not show differences from vehicle treatment in treatment emergent adverse events or serious emergent adverse events incidence. In studies with low risk of bias, PDE4 inhibitors had a statistically significant risk of producing pain and reduced occurrence of atopic dermatitis exacerbation.

Project description:ImportanceBaricitinib, an oral selective Janus kinase 1 and 2 inhibitor, effectively reduced disease severity in moderate to severe atopic dermatitis (AD) in 2 phase 3 monotherapy studies.ObjectiveTo assess the efficacy and safety of 4 mg and 2 mg of baricitinib in combination with background topical corticosteroid (TCS) therapy in adults with moderate to severe AD who previously had an inadequate response to TCS therapy.Design, setting, and participantsThis double-blind, placebo-controlled, phase 3 randomized clinical trial, BREEZE-AD7 (Study of Baricitinib [LY3009104] in Combination With Topical Corticosteroids in Adults With Moderate to Severe Atopic Dermatitis) was conducted from November 16, 2018, to August 22, 2019, at 68 centers across 10 countries in Asia, Australia, Europe, and South America. Patients 18 years or older with moderate to severe AD and an inadequate response to TCSs were included. After completing the study, patients were followed up for up to 4 weeks or enrolled in a long-term extension study.InterventionsPatients were randomly assigned (1:1:1) to receive 2 mg of baricitinib once daily (n = 109), 4 mg of baricitinib once daily (n = 111), or placebo (n = 109) for 16 weeks. The use of low-to-moderate potency TCSs was allowed.Main outcomes and measuresThe primary end point was the proportion of patients achieving a validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) score of 0 (clear) or 1 (almost clear), with a 2-point or greater improvement from baseline at week 16.ResultsAmong 329 patients (mean [SD] age, 33.8 [12.4] years; 216 [66%] male), at week 16, a vIGA-AD score of 0 (clear) or 1 (almost clear) was achieved by 34 patients (31%) receiving 4 mg of baricitinib and 26 (24%) receiving 2 mg of baricitinib compared with 16 (15%) receiving placebo (odds ratio vs placebo, 2.8 [95% CI, 1.4-5.6]; P = .004 for the 4-mg group; 1.9 [95% CI, 0.9-3.9]; P = .08 for the 2-mg group). Treatment-emergent adverse events were reported in 64 of 111 patients (58%) in the 4-mg group, 61 of 109 patients (56%) in the 2-mg group, and 41 of 108 patients (38%) in the placebo group. Serious adverse events were reported in 4 patients (4%) in the 4-mg group, 2 (2%) in the 2-mg group, and 4 (4%) in the placebo group. The most common adverse events were nasopharyngitis, upper respiratory tract infections, and folliculitis.Conclusions and relevanceA dose of 4 mg of baricitinib in combination with background TCS therapy significantly improved the signs and symptoms of moderate to severe AD, with a safety profile consistent with previous studies of baricitinib in AD.Trial registrationClinicalTrials.gov Identifier: NCT03733301.

Project description:ImportanceTopical calcineurin inhibitors (TCIs), primarily used to treat atopic dermatitis (AD), carry a black box label warning users about the potential for increased skin cancer risk. The risk associated with keratinocyte carcinoma (KC), the most common cancer, defined as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), remains poorly defined because findings from large-scale postmarketing surveillance studies have not been reported.ObjectivesTo examine KC risk overall and by subtype (BCC and SCC) among adults with AD exposed to TCIs compared with those exposed to topical corticosteroids (primary comparator group) and those unexposed to TCIs or topical corticosteroids (alternative comparator group) as well as alterations in risk with TCI dose, frequency, and duration of exposure.Design, setting, and participantsA retrospective cohort study was conducted at Kaiser Permanente Northern California, a large, integrated health care delivery system, of adults 40 years or older (n = 93 746) with a physician-rendered diagnosis of AD or dermatitis. Patients who were diagnosed from January 1, 2002, to December 31, 2013, were included, with follow-up through December 31, 2017. Data analysis was conducted from June 1, 2016, to October 1, 2018.ExposuresTime-varying pharmacy-dispensed TCI exposure (n = 7033) over the study period was compared with topical corticosteroids (n = 73 674) and no TCI or topical corticosteroid exposure (n = 46 141).Main outcomes and measuresElectronic pathologic testing-validated incident KCs (n = 7744).ResultsAmong a cohort of 93 746 members, the mean (SD) age was 58.5 (12.7) years, and 55 023 patients (58.7%) were women. Multivariable Cox proportional hazards regression revealed no association between TCI exposure and KC risk (adjusted hazard ratio [aHR], 1.02; 95% CI, 0.93-1.13) compared with topical corticosteroid exposure. Similarly, there were no significant differences in BCC risk (aHR, 1.01; 95% CI, 0.90-1.14, TCI vs topical corticosteroids) or SCC risk (aHR, 0.94; 95% CI, 0.82-1.08, TCI vs topical corticosteroids). Changing the comparator group to unexposed individuals yielded similar findings (aHR, 1.04; 95% CI, 0.91-1.19, TCI vs unexposed for basal cell carcinoma). There were no associations between TCI dose, frequency, and duration of use and BCC, SCC, or overall KC risk.Conclusions and relevanceThe results of this postmarketing surveillance study of adult health plan members with AD revealed no apparent association between TCI exposure and overall KC, BCC, or SCC risk. Secondary analyses examining dose, frequency, and duration of TCI exposure revealed no associations. These findings suggest that use of TCIs may be safe with respect to KC risk among adults with AD.

Project description:Background: The use of Chinese herbal medicine (CHM) for the treatment of atopic dermatitis (AD) has gained attention. This quantitative study systematically evaluated the efficacy and safety of CHM for the treatment of AD in eight high-level clinical trials, resulting in a high level of clinical evidence. Methods: Several databases were searched, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), the Chongqing VIP Chinese Science (VIP), and Wanfang Database. High-quality randomized controlled trials (RCTs) comparing CHM with placebo were included. The 95% confidence interval (CI) of the risk ratio (RR) was calculated using software (RevMan 5.3) and a meta-analysis was performed. Evidence level evaluation using GRADE Profiler 3.6. Results: In total, 662 patients (322 in the experimental group and 340 in the control group) were included. The response rate of the Eczema Area and Severity Index (EASI) -90 was higher in the CHM group than in the placebo group (RR, 3.72; 95% CI, 1.76 to7.83; p = 0.01). Furthermore, the scoring of atopic dermatitis (SCORAD) (RR, -10.20), body surface area (BSA) (RR, -2.01), surface damage score (RR, -2.25), visual analog scale (VAS) (RR, -1.90), and sleep score (RR, -2.16), improvement of investigator's global assessment (IGA) (RR, 2.94) improved in the CHM group. The results showed no statistical difference between CHM and placebo (MD, -0.47; 95% CI, -1.30, 0.37; p = 0.27) in improving the Dermatology Life Quality Index (DLQI) or children's DLQI (CDLQI). There was also no significant difference in the IgE level between the two groups (MD, -62.76; 95% CI, -809.58, 684.05; p = 0.87). However, the adverse events (AEs) rate was slightly higher in patients treated with CHM than in those treated with placebo (RR, 1.42; 95% CI, 1.06-1.90; p = 0.02). Conclusion: CHM improved the size and severity of the skin lesions and sleep quality in patients with AD. Comparing the adverse effects between the two groups, CHM is safe. However, CHM does not improve the quality of life or the patient's IgE levels.
