Efficacy and safety of tacrolimus ointment compared with that of hydrocortisone butyrate ointment in adult patients with atopic dermatitis

BACKGROUND: Vehicle-controlled studies have demonstrated the efficacy and safety of tacrolimus ointment for patients with atopic dermatitis. OBJECTIVE: This study was undertaken to compare 0.03% and 0.1% tacrolimus ointment with 0.1% hydrocortisone-17-butyrate ointment, a midpotent to potent topical corticosteroid, in the treatment of adult patients with moderate-to-severe atopic dermatitis. METHODS: Patients applied ointment twice daily to all affected areas for 3 weeks in this multicenter, randomized, double-blind, parallel-group study. The primary endpoint was the modified eczema area and severity index (mEASI) mean area under the curve as a percentage of baseline. RESULTS: Five hundred seventy patients were randomized and received treatment. Discontinuations included 22 of 193 patients from the 0.03% tacrolimus group, 22 of 191 patients from the 0.1% tacrolimus group, and 17 of 186 patients from the hydrocortisone butyrate group. The median mEASI mean area under the curve as a percentage of baseline was 47.0%, 36.5%, and 36.1% for patients who received 0.03% tacrolimus, 0.1% tacrolimus, and 0.1% hydrocortisone butyrate, respectively. There was no statistically significant difference between 0.1% tacrolimus and 0.1% hydrocortisone butyrate; however, the lower improvement in mEASI for 0.03% tacrolimus was statistically significant when compared with 0.1% tacrolimus (P <.001) or hydrocortisone butyrate (P =.002). Skin burning and pruritus at the application site showed a higher incidence in the tacrolimus treatment groups than in the hydrocortisone butyrate group (P <.05). Laboratory parameters showed no treatment differences and no marked changes over time. CONCLUSIONS: The efficacy of 0.1% tacrolimus ointment was similar to that of 0.1% hydrocortisone butyrate ointment and was lower for 0.03% tacrolimus ointment. No serious safety concerns were identified.     

Efficacy and safety of methylprednisolone aceponate ointment 0.1% compared to tacrolimus 0.03% in children and adolescents with an acute flare of severe atopic dermatitis

BACKGROUND: Topical glucocorticosteroids are the gold standard in treatment of atopic dermatitis (AD). Recently, topical calcineurin inhibitors have been developed for treatment of this condition. This study compared efficacy and safety of 0.1% methylprednisolone aceponate (MPA) ointment with 0.03% tacrolimus ointment for 3 weeks, in children and adolescents with severe to very severe flare of AD. METHODS: The primary end point was treatment success, defined as a score of 'clear' or 'almost clear' in the static Investigator's Global Assessment (IGA) score. Secondary end points were the percentage change in the Eczema Area and Severity Index (EASI) and patients' assessment of itch and sleep, Children's Dermatology Life Quality Index, patient's assessment of global response, affected Body Surface Area and medication costs. RESULTS: 265 patients were randomized to either MPA (n = 129) or tacrolimus (n = 136) treatment, 257 patients completed the study. Methylprednisolone aceponate 0.1% ointment once daily provided rapid and relevant clinical benefit. Tacrolimus 0.03% ointment twice daily was equally effective with regard to success rate. Methylprednisolone aceponate was superior to tacrolimus for EASI, itch and sleep. Both treatments were well tolerated. Drug-related adverse events were only observed in the tacrolimus group. Medication costs were significantly lower for MPA. CONCLUSIONS: While both treatment groups showed similar efficacy results regarding treatment success (IGA), significant advantages were observed for EASI, itch and sleep with MPA 0.1%. These advantages and the significantly lower treatment costs highlight the benefits of MPA treatment, underlining its first-line role in treatment of children and adolescents with severe AD.     

Proactive treatment of atopic dermatitis in adults with 0.1% tacrolimus ointment

Background:  Long-term treatment for atopic dermatitis (AD) using low dose, intermittent, topical anti-inflammatory agents may control acute disease and prevent relapses. This 12-month, European, multicentre, randomized study investigated whether the proactive use of 0.1% tacrolimus ointment applied twice weekly can keep AD in remission and reduce the incidence of disease exacerbations (DE).
Methods:  During the initial open-label period, 257 adults with AD applied 0.1% tacrolimus ointment twice daily (b.i.d.) for up to 6 weeks to affected areas. When an Investigator Global Assessment (IGA) score of ≤2 was achieved, the patient entered the disease control period (DCP) and was randomized to either proactive tacrolimus ( n  = 116) or vehicle ointment ( n  = 108) twice weekly for 12 months. Exacerbations were treated with 0.1% tacrolimus ointment b.i.d. until an IGA ≤2 was regained, then randomized treatment was restarted. The primary endpoint was the number of DEs during the DCP that required a substantial therapeutic intervention.
Results:  Proactive tacrolimus 0.1% ointment application significantly reduced the number of DEs requiring substantial therapeutic intervention (median difference 2; P  < 0.001; Wilcoxon rank sum test), the percentage of DE treatment days (median difference: 15.2%; P  < 0.001; Wilcoxon rank sum test) and increased the time to first DE (median 142 vs 15 days; P  < 0.001; stratified log-rank test). The adverse event profile was similar for the two treatment approaches.
Conclusion:  A 12-month, twice weekly proactive tacrolimus ointment application was an effective treatment in most study patients which prevented, delayed and reduced the occurrence of AD exacerbations.

Comparing tacrolimus ointment and oral cyclosporine in adult patients affected by atopic dermatitis: a randomized study

BACKGROUND: Atopic dermatitis (AD) is a chronic allergic inflammatory disease, which manifests itself with eczematous skin lesions. OBJECTIVE: We compared the clinical efficacy of tacrolimus ointment (0.1%) given twice a day and oral cyclosporine (3 mg/kg) given once daily. Rescue medication for itching included cetirizine 10-20 mg (equal to one or two tables). METHODS: Thirty patients, aged 13-45 years (mean+/-SD 27.1+/-10.9), with a history of moderate-to-severe AD were randomized to treatments, 15 patients for each treatments. Assessment of efficacy was based on SCORAD, on scores of daily itching, erythema, interference with sleep, due to the skin condition and days without use of cetirizine tablets. SCORAD, measured on a scale (0-103), was evaluated before treatment (0) and at 7, 14, 21, 28, 35 and 42 days after treatment. Similarly, the means of daily symptoms, on a scale (0-3), were evaluated before the treatment (0) and at 7, 14, 21, 28, 35 and 42 days after treatment; finally, on day without use of cetirizine tablets. The safety of the study treatments was assessed through haematologic, biochemical and urinary testing and on systolic and diastolic blood pressures and heart rate measurements. RESULTS: SCORAD decreased in the two treatment groups 14 days after the beginning of the period study. However, the patients in tacrolimus ointment group reported significantly lower SCORAD than those treated with oral cyclosporine. Overall SCORAD, as assessed by the area under the curve (AUC) day(0-42) (score/day), was significantly lower in the tacrolimus ointment group when compared with oral cyclosporine (P<0.001). Similarly, AUC day(0-42) (score/day) for itching, erythema and number of nights without interference with the sleep due to skin condition were significantly lower in the group of patients treated with tacrolimus compared with those treated with cyclosporine (P=0.003, 0.005 and 0.01, respectively). As regards the use of rescue medication, expressed by median of number of days without use of anti-H(1), it was significantly lower in the group treated with tacrolimus (82.5) than in the cyclosporine group (76.5) (P=0.03). There were no appreciable changes in haematological and biochemical indices, in both treatments groups. CONCLUSION: The results of this comparative study demonstrate that tacrolimus ointment twice daily and cyclosporine administered orally once daily are effective on SCORAD, daily symptoms and anti-H(1) rescue. When we compared tacrolimus and cyclosporine there was a faster onset of action in the group treated with tacrolimus. The two drugs presented the same safety. However, these data support the preferential use of topical tacrolimus 0.1% in AD, because cyclosporine has potential side-effects.     

Tacrolimus ointment causes inflammatory dendritic epidermal cell depletion but no Langerhans cell apoptosis in patients with atopic dermatitis

BACKGROUND: The topical immunomodulators tacrolimus and pimecrolimus are novel therapeutic options for atopic dermatitis (AD). The inhibition of nuclear factor of activated T cell-dependent proinflammatory cytokine production in cutaneous lymphocytes is an established effect of topical immunomodulators, which additionally influence mast cells, eosinophils, and dendritic cells (DCs). The latter include a reduced expression of the high-affinity IgE receptor FcepsilonRI, a reduced stimulatory capacity of lesional DCs, and a selective depletion of the inflammatory dendritic epidermal cells (IDECs) but not of Langerhans cells (LCs) from the lesional skin. OBJECTIVE: Because induction of apoptosis in lymphocytes is a reported tacrolimus effect, we asked whether tacrolimus ointment induces apoptosis of LCs or IDECs in AD lesions. METHODS: Epidermal single-cell suspensions were prepared from AD lesions of 9 tacrolimus-treated and 5 hydrocortisone butyrate-treated patients with AD before and after 1 week of treatment. Cell numbers, apoptosis rate, and immunophenotype were assessed by using the standardized FACS technique with terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling, Annexin V, and 3-color immunophenotyping. Freshly isolated LCs and monocyte-derived DCs served as in vitro controls. RESULTS: Tacrolimus and steroid ointment induced a selective depletion of IDECs from the epidermis and reduced the expression of the costimulatory molecules CD80 and CD86. Tacrolimus ointment did not increase the rate of apoptotic DCs, whereas steroid ointment did so. The isolation-induced high apoptosis rate of freshly isolated LCs was unaffected by both drugs. CONCLUSION: Tacrolimus ointment selectively depletes IDECs and alters the immunophenotype of epidermal DCs in AD lesions, but there is no evidence for tacrolimus-induced DC apoptosis in this phenomenon.     

Topical application of FK506 (tacrolimus) ointment inhibits mite antigen-induced dermatitis by local action in NC/Nga mice

BACKGROUND: FK506 ointment (tacrolimus ointment, protopic) is a new drug therapeutically effective for patients with atopic dermatitis (AD). However, the mechanism of action of FK506 ointment on AD is not fully understood. METHODS: We examined the effect of FK506 ointment on mite antigen-induced dermatitis in NC/Nga mice. Clinical symptoms and ear thickness were recorded, and histopathological studies and in vitro analyses were performed. RESULTS: Topical application of FK506 ointment (0.03-0.3%) suppressed the development of dermatitis. In the lesional skin, both interleukin (IL)-4 and interferon (IFN)-gamma were detected, even though the IL-4+/IFN-gamma- T helper 2 (Th2) population was predominant in the regional lymph nodes (LNs). Topical application of FK506 treatment reduced the elevated level of both IL-4 and IFN-gamma in the skin, but did not decrease the expansion of the Th2 population in the LNs. CONCLUSIONS: Topical application of FK506 ointment suppresses dermatitis by inhibiting the activation of inflammatory cells locally, without systemic immune suppression, in this AD model.     

Efficacy and tolerance of tacrolimus and pimecrolimus for atopic dermatitis: a meta-analysis

Tacrolimus ointment and pimecrolimus cream have proved to be suitable for the treatment of atopic dermatitis. We conducted a meta-analysis of the efficacy, adverse events/withdrawal of tacrolimus versus pimecrolimus in the treatment of atopic dermatitis. According to our meta-analysis, 0.1% tacrolimus was more effective than 1% pimecrolimus in the treatment of adult patients and moderate to very severe pediatric patients, and more 0.1% mild pediatric patients treatal with pimecrolimus withdrew from the trials because of a lack of efficacy or the occurrence of adverse events, compared with mild pediatric patients treated with 0.03% tacrolimus. The combined analyses of tacrolimus with pimecrolimus showed that tacrolimus was more effective than pimecrolimus (week 3: RR=0.67, 95% CI=0.56-0.80; week 6/end of study: RR=0.65, 95% CI=0.57-0.75), and fewer tacrolimus-treated patients withdrew because of a lack of efficacy (RR=0.32, 95CI%=0.19-0.53) or the occurrence of adverse events (RR=0.43, 95% CI=0.24-0.75), compared with pimecrolimus-treated patients. In conclusion, tacrolimus has higher efficacy and better tolerance than pimecrolimus in the treatment of atopic dermatitis.     

Modulation of the atopy patch test: tacrolimus 0.1% compared with triamcinolone acetonide 0.1%

BACKGROUND: The atopy patch test (APT) is an in vivo model to study the induction of eczema by inhalant allergens in atopic dermatitis patients. We studied the effect of pretreatment with topical tacrolimus 0.1% on APT in nonlesional skin of patients with atopic dermatitis. METHODS: Nonlesional skin of the back of patients with atopic dermatitis (n = 8) was treated once daily for 3 weeks with tacrolimus 0.1% ointment. Cetomacrogol ointment (placebo) was used as a negative control and triamcinolone acetonide 0.1% ointment as positive control. Twenty-four hours after the last APT application, samples were taken from the three treated areas (t = 0 and 24 h) for immunohistochemical analysis. RESULTS: Pretreatment with tacrolimus ointment did not suppress nonlesional skin infiltrate, in contrast to triamcinolone acetonide. Furthermore, tacrolimus did not inhibit the induction of the APT macroscopically (t = 24 h). An equal influx of T cells, eosinophils, dendritic cells, CD64+ and Fc epsilon RI-positive cells was present compared with placebo. Only CD36+ and CD68-positive cells were inhibited compared with placebo. All cell types were significantly inhibited in triamcinolone acetonide-treated sites compared with placebo. CONCLUSIONS: Pretreatment with tacrolimus 0.1% ointment does not inhibit the APT reaction in patients with atopic dermatitis.     

Occlusive versus nonocclusive calcipotriol ointment treatment for palmoplantar psoriasis.

Thirty-nine patients with a clinical diagnosis of palmoplantar psoriasis [23 (58%) males and 16 (42%) females] were included in this study with the aim of evaluating the efficacy of occlusive calcipotriol 50 micrograms/mg ointment vs. nonocclusive therapy. Patients were randomized to either twice-weekly overnight calcipotriol ointment under occlusion or twice-daily topical nonocclusive application of the same ointment for 6 weeks. The effect of treatment was assessed on the basis of a psoriasis signs score for erythema, thickness and scaliness, which was graded from 0 (absent) to 4 (most severe) at the first visit, after 2 weeks and at the end of treatment. Analysis of our results showed that twice-weekly occlusive calcipotriol ointment was as effective as the twice-daily application. The mean total score at baseline was 6 for the occlusive group and 6.1 for the nonocclusive group. The score decreased to 1.5 in both groups at the end of treatment. No significant adverse effects were reported by patients or investigators. We conclude that occlusive calcipotriol ointment is effective in the treatment of palmoplantar psoriasis and may produce even better results with more frequent use, such as application on alternate days.     

Respiratory symptoms, bronchial hyper-responsiveness, and eosinophilic airway inflammation in patients with moderate-to-severe atopic dermatitis

BACKGROUND: Patients with atopic dermatitis (AD) often have symptoms suggestive of asthma or rhinitis. The prevalence and signs of respiratory disease in AD patients have been studied to a limited extent. OBJECTIVES: To assess the prevalence and clustering of respiratory symptoms, bronchial hyper-responsiveness (BHR), and eosinophilic airway inflammation in patients with moderate-to-severe AD. METHODS: Eighty-six consecutive patients with moderate-to-severe AD and 49 randomly selected control subjects without AD were studied by questionnaire, flow volume spirometry, histamine challenge to detect BHR, induced sputum test to detect eosinophilic airway inflammation, and skin prick tests (SPTs) and total serum immunoglobulin (Ig)E measurements to detect atopy. RESULTS: The patients with AD showed increased risk of physician-diagnosed asthma (36% vs. 2%, odds ratio (OR) 10.1, confidence interval (CI) 1.3-79.7, P=0.03), physician-diagnosed allergic rhinitis (AR) (45% vs. 6%, OR 4.5, CI 1.2-16.7, P=0.02), BHR (51% vs. 10%, OR 5.5, CI 1.5-20.1, P=0.01), and sputum eosinophilia (81% vs. 11%, OR 76.1, CI 9.3-623.5, P<0.0001) compared with the control subjects. In AD patients, elevated s-IgE and positive SPTs were associated with the occurrence of physician-diagnosed asthma and AR, BHR, and the presence of sputum eosinophilia. CONCLUSIONS: BHR and eosinophilic airway inflammation are more common in patients with AD than in control subjects. The highest prevalences were seen in patients with AD who were SPT positive and had high IgE levels. Longitudinal studies are needed to assess the outcome of patients with signs of airway disease, in order to identify those who need early initiation of asthma treatment.     

Staphylococcus colonization in atopic dermatitis treated with fluticasone or tacrolimus with or without antibiotics.

BACKGROUND: The skin of patients with atopic dermatitis (AD) exhibits a striking susceptibility to colonization and infection by Staphylococcus aureus. Treatment with topical anti-inflammatory drugs alone can reduce S. aureus colonization. OBJECTIVES: To compare the clinical severity of AD and the S. aureus colonization rate between AD patients treated with topical glucocorticoids and those treated with tacrolimus and to evaluate the effects of complementary topical antistaphylococcal antibiotic therapy and the development of fusidic acid-resistant S. aureus. METHODS: Sixty AD patients were enrolled in a prospective, parallel, randomized study of an 8-week treatment with topical 0.05% fluticasone propionate or 0.03% tacrolimus, with or without complementary fusidic acid. Disease severity scoring of AD based on SCORing of Atopic Dermatitis (SCORAD), colonization rate and density of S. aureus on the skin, and antibiotic susceptibility of S. aureus isolates were evaluated. RESULTS: The reduction in SCORAD scores correlated with the reduction of S. aureus numbers. Treatment with topical tacrolimus resulted in a comparable reduction in SCORAD scores to fluticasone but a slower eradication of S. aureus. Complementary fusidic acid had no additional benefit compared with fluticasone or tacrolimus alone. Two patients developed fusidic acid-resistant S. aureus after 8 weeks of fusidic acid treatment. CONCLUSION: Tacrolimus is an appropriate alternative treatment for chronic AD. Topical anti-inflammatory therapy alone to improve the allergic skin inflammation of AD can reduce S. aureus colonization of the skin. Topical antibiotics should be reserved for short-term use in obvious secondary bacterial infection.     

Killed Mycobacterium vaccae suspension in children with moderate-to-severe atopic dermatitis: a randomized, double-blind, placebo-controlled trial

BACKGROUND: The hygiene hypothesis is often proposed to explain the high prevalence of atopy in the western world. Dysregulation of the immune system may result from inadequate exposure to micro-organisms such as mycobacteria. A small trial suggested that a killed extract of Mycobacterium vaccae ameliorates atopic dermatitis (AD). OBJECTIVES: To confirm in a large clinical trial whether killed M. vaccae ameliorates AD in 5-16-year-old children. METHODS: This was a randomized, placebo-controlled, double-blind, multi-centre study of the effect of intradermal injection of killed M. vaccae (0.1 or 1 mg) on patients, aged 5-16, with moderate-to-severe AD. Patients were followed up for 24 weeks. The primary end point was the change in severity of AD at 12 weeks, assessed using the six area, six-sign, atopic dermatitis (SASSAD) score. Secondary end points included changes in disease extent, patient's global assessment and children's dermatology life quality index. RESULTS: There were 166 patients randomized. The mean SASSAD score fell to a similar degree at week 12 in all treatment arms: from 33 to 24, (26%) in the high-dose group, from 30 to 23 (25%) in the low-dose group and from 36 to 27 (24%) in the placebo group (P>0.05). Secondary end points followed the same trend. Adverse events were generally those expected to occur in this population. Injection site reactions occurred in 32 patients at week 4. CONCLUSIONS: M. vaccae was no more effective than the placebo in ameliorating the severity of AD.     

Topical Fluticasone Propionate

Fluticasone propionate is a fluoromethyl androstane 17beta-carbiothioate that is classified for dermatological use as a moderate potency corticosteroid. It is available in 0.05% cream and 0.005% ointment formulations for the treatment of patients with inflammatory dermatoses responsive to corticosteroids. Although it demonstrates greater activity than other corticosteroids of similar potency in vasoconstrictor assays in humans, fluticasone propionate demonstrates low potential to cause significant systemic effects such as suppression of the hypothalamopituitary-adrenal (HPA) axis. This is because it has a high affinity for the glucocorticoid receptor and high lipophilicity, and the small amount of drug that is absorbed is rapidly metabolised to the inactive carboxylic acid derivative in the liver (i.e. it has low systemic bioavailability). In clinical trials, the efficacy of fluticasone propionate cream at 4 weeks did not differ significantly from that of hydrocortisone butyrate 0.1% cream in patients with moderate to severe atopic dermatitis and betamethasone valerate 0.1% cream in patients with moderate to severe psoriasis. Likewise, after 4 weeks, the ointment form of fluticasone propionate had similar efficacy to betamethasone dipropionate 0.05% in patients with psoriasis or atopic dermatitis, although the latter agent may have a faster onset of activity in patients with atopic dermatitis. Fluticasone propionate ointment was generally more effective than hydrocortisone butyrate ointment in patients with psoriasis. A sustained response was usually observed after about 1 week's application of fluticasone propionate, and although once and twice daily administration had similar efficacy, a twice daily regimen may have a slightly faster onset of effect. In trials which included both adults and children, the only adverse events reported were local cutaneous reactions (most frequently, pruritus). Thus, fluticasone propionate, with its low potential for systemic toxicity and possible advantage of once daily administration, is a useful addition to the topical corticosteroids available for the treatment of psoriasis and atopic dermatitis.

A report of clinical trial conducted on Toto ointment and soap products

OBJECTIVE: The efficacy of Toto ointment and soap on common skin disorders was tested. METHODOLOGY: A cohort of Nigerians with common skin conditions such as fungal and bacterial skin infections, scabies, acne vulgaris, and dandruff were selected and followed for a period of 12 weeks. The study is a randomized, comparative, prospective, blinded observational study. Following a placebo run in/wash out period, patients were given either a Toto ointment or soap, or a combination of these, or sulfur ointment alone. Soap use was preferred in patients with Tinea capitis more than patients with any other superficial skin condition for technical reasons--such as ease of application of the soap lather. Expressed preference for either the soap or the cream was at times taken into consideration. Cure rate, adverse drug effects and acceptability of the products were assessed. RESULTS: Out of the 595 patients with common skin diseases selected for the study, 446 (74.9%) had fungal infections, while 64 (10.8%) had scabies infestation. A total of 47 (7.9%) patients had bacterial skin infections, 36 (6.1%) had acne vulgaris, and two (0.3%) had dandruff. At the end of the treatment period, out of the 129 patients with fungal infections treated with Toto ointment alone, 92 (71.3)% were successfully treated; while 41 (87.2%) out of the 47 patients with scabies were successfully treated with Toto ointment alone. Although few patients were seen with bacterial skin infections during the study period, these patients responded well to the ointment, the soap or a combination of the two. Overall, the combination of Toto ointment and soap had a better clinical success rate on all diseases when compared to sulfur ointment alone. The study has shown the efficacy and tolerability of Toto products (skin ointment and soap) in the management of common skin disorders. CONCLUSION: Toto ointment and soap are particularly efficacious in the management of common skin conditions such as fungal and bacterial skin infections, scabies, acne vulgaris and dandruff.     

A comparison of injections of botulinum toxin and topical nitroglycerin ointment for the treatment of chronic anal fissure.

BACKGROUND AND METHODS: Lateral internal sphincterotomy, the most common treatment for chronic anal fissure, may cause permanent injury to the anal sphincter, which can lead to fecal incontinence. We compared two nonsurgical treatments that avert the risk of fecal incontinence. We randomly assigned 50 adults with symptomatic chronic posterior anal fissures to receive treatment with either a total of 20 U of botulinum toxin injected into the internal anal sphincter on each side of the anterior midline or 0.2 percent nitroglycerin ointment applied twice daily for six weeks. RESULTS: After two months, the fissures were healed in 24 of the 25 patients (96 percent) in the botulinum-toxin group and in 15 of the 25 (60 percent) in the nitroglycerin group (P=0.005). No patient in either group had fecal incontinence. At some time during treatment, five patients in the nitroglycerin group had transient, moderate-to-severe headaches that were related to treatment. None of the patients in the botulinum-toxin group reported adverse effects. Ten patients who did not have a response to the assigned treatment - 1 in the botulinum-toxin group and 9 in the nitroglycerin group - crossed over to the other treatment; the fissures subsequently healed in all 10 patients. There were no relapses during an average of about 15 months of follow-up. CONCLUSIONS: Although treatment with either topical nitroglycerin or botulinum toxin is effective as an alternative to surgery for patients with chronic anal fissure, botulinum toxin is the more effective nonsurgical treatment.     

Health-related quality of life with tralokinumab in moderate-to-severe atopic dermatitis: A phase 2b randomized study

BackgroundAtopic dermatitis (AD) is associated with a substantial burden on quality of life (QoL).ObjectiveTo evaluate the effects of tralokinumab on health-related QoL in patients with moderate-to-severe AD using patient-reported outcomes.MethodsThis was a phase 2b, randomized, double-blind, placebo-controlled, dose-ranging study in adults with moderate-to-severe AD. The patients received subcutaneous tralokinumab or placebo (1:1:1:1) every 2 weeks for 12 weeks and class 3 topical corticosteroid cream or ointment at least once daily from the run-in to end of follow-up. Patient-reported outcome end points were change from baseline to week 12 in the Dermatology Life Quality Index (dermatology life quality index (DLQI); prespecified secondary objective), the Short Form 36 Health Survey (SF-36) version 2, and sleep interference numeric rating scale score (prespecified exploratory objectives).ResultsA total of 204 patients were randomized to placebo (n = 51) or tralokinumab (45 mg, n = 50; 150 mg, n = 51; 300 mg, n = 52). Tralokinumab 300 mg every 2 weeks improved total Dermatology Life Quality Index vs placebo at week 12 (placebo-adjusted mean change, ?3.51 [95% confidence interval, ?6.00 to ?1.02]). At week 12, both the mental component summary (4.23 [0.98-7.47]) and the physical component summary (4.26 [1.83-6.69]) and all 8 domains of the Short Form 36 Health Survey were improved in patients treated with tralokinumab 300 mg vs placebo. Sleep interference was improved at week 12 with all tralokinumab doses vs placebo.ConclusionTralokinumab improved health-related QoL in patients with moderate-to-severe atopic dermatitis, providing further evidence of the value of targeting interleukin-13 in such patients.Trial RegistrationClinicalTrials.gov identifier: NCT02347176; https://clinicaltrials.gov/ct2/show/NCT02347176.     

2% Crisaborole topical ointment for the treatment of mild-to-moderate atopic dermatitis

Introduction: Crisaborole 2% topical ointment is an anti-inflammatory, non-steroidal phosphodiesterase 4 inhibitor which is currently under investigation for its potential role in the treatment of atopic dermatitis and psoriasis.

Areas covered: So far, 7 trials have been completed in atopic dermatitis. The 2% strength appeared to be the superior dosing regimen. Pruritus improved significantly within one week. The improvements in objective efficacy assessments in crisaborole-treated patients were also statistically significant compared to the vehicle.

Expert commentary: Crisaborole has several key features in its mode of action which distinguish it from existing treatments for atopic dermatitis (AD), notably its activity against the phosphodiesterase E4 (PDE4) pathway, regulating cyclic AMP (cAMP) levels. This is less immunosuppressive than other pathways and has no effect on skin thinning. The pathway interrupts the itch sensation (pruritus) which means that the itch-scratch cycle, the bane in the life of patients with AD, is interrupted, usually as early as a few days into treatment. Hence, with the promising safety profile demonstrated, early treatment of mild to moderate AD patients might help to control AD better and improve quality of life for patients.
