Atopic dermatitis: a candidate for disease-modifying strategy.

The concept of disease modification has been introduced to define the therapeutic strategies aimed to break, stop, or reverse the natural course of a chronic invalidating disease. This strategy is tightly related to the biomarker-based stratification of affected patients using genetic and other biological markers. With regard to the progress in understanding the genetic background of atopic dermatitis (AD), its natural history and its pivotal role in the emergence of allergic asthma, the time is mature to foster the research field of biomarkers in AD and to consider the elaboration of disease-modifying strategies in the management of AD with the goal to stop or even reverse the atopic march.

The novel protease inhibitor SRD441 ointment is not effective in the treatment of adult subjects with atopic dermatitis: results of a randomized, vehicle-controlled study.

BACKGROUND: There is evidence that excessive protease activity in the skin is an important factor in the development of atopic dermatitis. SRD44 is a topically formulated novel protease inhibitor that selectively inhibits Staphylococcal-derived aureolysin and matrix metalloproteinases (MMPs). METHODS: This was a double-blind, vehicle-controlled randomized trial conducted in thirteen hospital dermatology outpatient clinics in Germany (9), Bulgaria (3) and Finland (1). Ninety-three out of 103 screened adult subjects with confirmed atopic dermatitis affecting ≤ 20% of body surface area, with an IGA score of 2 or 3 at randomization were randomized following a washout period to either SRD441 ointment or matching vehicle twice daily for 28 days. The primary efficacy endpoint was the clearance of Atopic dermatitis (AD score of 0 or 1 IGA) at Day 21. Secondary endpoints included measures of SCORing Atopic Dermatitis, pruritus self-assessment, rescue medication use and occurrence of new exacerbations. A range of safety and tolerance endpoints were included. RESULTS: There were no significant treatment differences in IGA success rates at Day 21 (SRD441 ointment, 11.1%; vehicle ointment, 12.5%; P = 1.000). Evaluation of secondary efficacy variables revealed no clinical or important statistical differences between treatment groups. Eighteen subjects (19.4%) discontinued the study drug because of an AE (seven subjects [15.6%] in the SRD441 group and 11 subjects [22.9%] in the vehicle group). Twenty-seven subjects (60.0%) in the SRD441 group and 34 subjects (70.8%) in the vehicle group reported an adverse event (AE). CONCLUSIONS: SRD441 ointment did not demonstrate efficacy in the treatment of atopic dermatitis raising questions on the effectiveness of MMPs as a target for the treatment of atopic dermatitis.

Superiority of tacrolimus 0.1% ointment compared with fluticasone 0.005% in adults with moderate to severe atopic dermatitis of the face: results from a randomized, double-blind trial.

BACKGROUND: No specific data are available on tacrolimus ointment as a second-line treatment in adults with facial eczema. OBJECTIVES: To compare tacrolimus 0.1% and fluticasone 0.005% ointments in adults with moderate to severe atopic dermatitis (AD) of the face in whom conventional treatment was ineffective or poorly tolerated. METHODS: Patients were randomized to double-blind treatment of facial AD with twice-daily tacrolimus ointment (n = 288) or fluticasone ointment (n = 280) for 3 weeks or until clearance. After day 21, patients could continue without the study treatment, apply the same ointment once daily, or switch to the other medication twice daily, depending on lesion clearance and patient/physician satisfaction. The primary endpoint was the day-21 response [> or = 60% reduction in the modified Local Eczema and Severity Index (mLEASI) score]. Secondary endpoints included facial erythema and pruritus, global clinical response, treatment switching at day 21 and safety. RESULTS Response with tacrolimus ointment (93%) was superior to that with fluticasone (88%; P = 0.026). Improvements in mLEASI components were also greater with tacrolimus ointment. Facial erythema and pruritus improved in both groups. Global clinical response was rated 'marked improvement' or better in 88% and 79% of patients in the tacrolimus ointment and fluticasone groups, respectively. At day 21, 9% of patients switched from fluticasone to tacrolimus ointment, while 4.5% switched from tacrolimus ointment to fluticasone. Adverse events were more frequent with tacrolimus ointment as a result of the higher incidence of application-site skin burning sensation. Safety of both drugs was in line with their respective summary of product characteristics. CONCLUSIONS: Tacrolimus 0.1% ointment has superior efficacy to fluticasone 0.005% ointment for twice-daily treatment of adults with moderate to severe facial AD in whom conventional therapy was inadequately effective or not tolerated. Tacrolimus 0.1% ointment is a safe and effective second-line treatment for the control of moderate to severe AD of the face.

Proactive disease management with 0.03% tacrolimus ointment for children with atopic dermatitis: results of a randomized, multicentre, comparative study.

BACKGROUND: Long-term treatment for atopic dermatitis (AD) using low-dose, intermittent, topical anti-inflammatory agents may control acute disease and prevent exacerbations. OBJECTIVES: This 12-month, European, multicentre, randomized study investigated if proactive, twice-weekly application of 0.03% tacrolimus ointment can keep AD in remission and reduce the incidence of disease exacerbation (DE) in children. PATIENTS AND METHODS: During the initial open-label period, 267 children with AD applied 0.03% tacrolimus ointment twice daily for up to 6 weeks to all affected areas. When an Investigator Global Assessment (IGA) score of

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

A 4-year follow-up study of atopic dermatitis therapy with 0.1% tacrolimus ointment in children and adult patients.

BACKGROUND: For the treatment of a chronic disease like atopic dermatitis, sustained tolerability and efficacy of the applied medication are essential. OBJECTIVES: The present open-label, noncomparative study was conducted to obtain information on the long-term safety and efficacy of 0.1% tacrolimus ointment. METHODS: Patients aged 2 years or older with an affected body surface area of more than 5%, who previously participated in a clinical trial on tacrolimus ointment, were eligible for this study. The treatment area was defined by the investigator at study entry. Both children and adults applied continuously or intermittently 0.1% tacrolimus ointment twice daily during episodes of active disease plus an additional week after remission over a follow-up period of up to 4 years. RESULTS: The intent-to-treat population comprised 782 patients, with a median age of 22 years (range 2-72). Patients remained in the study for up to 4 years. Approximately half of the patients discontinued the study prematurely; the median follow-up was 1422 days. Median tacrolimus ointment use was 31.2 g during the first week; ointment use decreased during the first year and then remained stable for the remainder of the study. The median cumulative tacrolimus use was 271.5 g at month 6, 462.5 g at month 12, 739.9 g at month 24, 1029.3 g at month 36 and 1320.8 g at month 48. Altogether 51.8% of patients discontinued the study prematurely; the main reasons were withdrawal of consent (13.3%), loss to follow-up (11.3%) and lack of efficacy (9.4%). Adverse events led to study discontinuation in 3.7% of the patients. The most frequent application site events were skin burning and pruritus. These events were most often reported in adult patients during the initial treatment period; prevalence decreased after the first week and remained at a low level throughout the study. Nonapplication site events occurred with stable incidences throughout the study period. In general, calculated daily hazard rates did not indicate an increased risk of adverse events with prolonged treatment. The total affected body surface area decreased substantially upon onset of treatment and efficacy of treatment was maintained until the end of the study with smaller but continuous improvements throughout the follow-up period. Overall, 75% of the patients and 76% of the investigators rated their satisfaction with the treatment as excellent, very good or good at the end of the study or at the time of premature discontinuation. CONCLUSIONS: The safety profile of intermittent or continuous long-term application of 0.1% tacrolimus ointment for up to 4 years was consistent with that which has been established from shorter studies and gave no reason for concern. In addition, 0.1% tacrolimus ointment demonstrated sustained efficacy as reflected by the expression of high satisfaction with treatment by both patients and investigators.

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 < or =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 < or =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.

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.

A multicentre, randomized, double-blind, controlled study of long-term treatment with 0.1% tacrolimus ointment in adults with moderate to severe atopic dermatitis.

BACKGROUND: Atopic dermatis (AD) is a chronic disease that often requires long-term treatment. Topical corticosteroids are the usual therapy for patients with AD, but prolonged usage can result in skin atrophy and other side-effects. OBJECTIVES: In a randomized, double-blind, comparative study, to compare the efficacy and safety of a 6-month treatment period with 0.1% tacrolimus ointment vs. a corticosteroid ointment regimen in adults with moderate to severe AD. METHODS: Treatment was applied twice daily for a maximum of 6 months. Patients in the tacrolimus treatment group (n = 487) applied 0.1% tacrolimus ointment to all affected areas over the whole body. The patients treated with the corticosteroid regimen (n = 485) applied 0.1% hydrocortisone butyrate ointment to affected areas on the trunk and extremities and 1% hydrocortisone acetate ointment to affected areas on the face and neck. The study primary endpoint was the response rate, i.e. the proportion of patients with at least 60% improvement in the modified Eczema Area and Severity Index (mEASI) between baseline and month 3. RESULTS: By month 3, more patients in the 0.1% tacrolimus group responded to treatment (72.6% vs. 52.3% in the corticosteroid group, P < 0.001). The patients treated with 0.1% tacrolimus also showed greater improvement in mEASI, EASI, affected body surface area and physician and patient assessments of global response. Patients applying 0.1% tacrolimus ointment experienced more skin burning (52.4% vs. 13.8% in the corticosteroid group; P < 0.001). In most patients, skin burning was mild to moderate in severity and decreased rapidly after the first week of treatment. There was no increase in the incidence of infections or malignancies over time in either treatment group. CONCLUSIONS: Long-term treatment with 0.1% tacrolimus ointment is significantly more efficacious than a corticosteroid ointment regimen in adults with moderate to severe AD.

Efficacy and tolerability of three different doses of oral pimecrolimus in the treatment of moderate to severe atopic dermatitis: a randomized controlled trial.

BACKGROUND: Adult atopic dermatitis (AD) can seriously affect quality of life of patients and their families, and patients' disease is frequently not satisfactorily controlled with topical therapy. There is a need for alternatives to topical treatment in patients with moderate to severe AD. OBJECTIVES: To investigate the efficacy and safety of oral pimecrolimus, and to determine the response to three different doses in the treatment of AD. METHODS: In a double-blind, placebo-controlled, parallel-group, dose-finding study, patients with moderate to severe AD were randomized to receive either placebo, or oral pimecrolimus 10, 20 or 30 mg twice daily. The study consisted of a pretreatment phase, a 12-week double-blind treatment phase, and a 12-week post-treatment phase. RESULTS: In total, 103 patients were randomized. A clear, dose-dependent therapeutic effect of pimecrolimus treatment was observed, with a statistically significant onset of efficacy at week 2 and the greatest reduction from baseline of the Eczema Area and Severity Index of 66.6% at week 7 in the 30 mg twice daily dose group. Oral pimecrolimus was well tolerated and there were no signs of nephrotoxicity or the induction of hypertension. CONCLUSIONS: These data demonstrate the clinically relevant efficacy and short-term safety of oral pimecrolimus in adults with moderate to severe AD. Longer-term studies in larger cohorts are now required.

The role of topical calcineurin inhibitors in atopic dermatitis.

For more than five decades, topical corticosteroids and emollients have been the mainstay of therapy for atopic dermatitis. However, the potential for side-effects limits the clinical utility of corticosteroids in providing long-term disease control. With a unique mode of action that differs from that of corticosteroids, the steroid-free topical calcineurin inhibitors (TCIs), tacrolimus ointment and pimecrolimus cream, provide skin-selective treatment that targets key factors involved in the pathogenesis of this chronic disease. An extensive series of clinical trials involving more than 16,000 patients with predominantly moderate to severe atopic dermatitis in tacrolimus studies and over 2000 patients with primarily mild to moderate disease in pimecrolimus studies has shown that both TCIs provide effective and well-tolerated treatment for atopic dermatitis. Randomized controlled trials have demonstrated that tacrolimus is superior to conventional hydrocortisone-based regimens and does not cause skin atrophy or other steroidal side-effects. Both tacrolimus and pimecrolimus prevent disease flares and provide progressive and sustained disease improvement with long-term therapy. These and other clinical benefits of TCIs are discussed, together with the safety profiles of tacrolimus and pimecrolimus and their use in clinical practice. In addition, this review summarizes findings from the many trials carried out with these agents and outlines how TCIs can provide long-term treatment and control of a chronic skin disease that may persist for years.

Effects of 1-year intermittent treatment with topical tacrolimus monotherapy on skin collagen synthesis in patients with atopic dermatitis.

BACKGROUND: Topical corticosteroids decrease collagen synthesis during short-term treatment and can induce skin atrophy when applied over the long term. In contrast, short-term tacrolimus ointment therapy does not affect collagen synthesis. OBJECTIVES: Our aim was to evaluate the long-term effects of 0.1% tacrolimus ointment on collagen synthesis and on skin thickness in adults with moderate to severe atopic dermatitis (AD) and to compare the findings with the effects of conventional steroid-based therapy. METHODS: Fifty-six patients with AD were treated with 0.1% tacrolimus ointment in a 1-year, open-label, prospective clinical trial. Thirty-six patients with AD applied conventional steroid-based therapy and 27 healthy subjects were recruited as controls. The primary endpoint was the change in levels of procollagen propeptides I and III measured by radioimmunoassay between baseline and month 12. Additional endpoints included the change in skin thickness measured by ultrasound between baseline and month 12. RESULTS: Procollagen propeptide baseline values were significantly lower in the group to be treated with tacrolimus ointment than in healthy controls. One-year treatment with tacrolimus ointment was associated with an increase in collagen synthesis; the median increase in combined procollagen propeptide levels was 272 micro g L-1 (+ 140.9%, P < 0.001) and was accompanied by a significant increase in skin thickness. In three patients with visible skin atrophy, this condition ameliorated. Corticosteroid-based therapy had no significant effect on collagen synthesis; the median increase in combined procollagen propeptide levels was 11 micro g L-1 (+ 3.9%). A significant reduction in skin thickness was demonstrated. CONCLUSIONS: Long-term tacrolimus ointment therapy in patients with AD is nonatrophogenic and reverses corticosteroid-induced skin atrophy.

0.03% Tacrolimus ointment applied once or twice daily is more efficacious than 1% hydrocortisone acetate in children with moderate to severe atopic dermatitis: results of a randomized double-blind controlled trial.

BACKGROUND: Topical corticosteroids are the usual treatment for atopic dermatitis (AD) in children but can have side-effects. OBJECTIVES: This study compared the efficacy and safety of 0.03% tacrolimus ointment applied once or twice daily over a 3-week period with the twice daily application of 1% hydrocortisone acetate (HA) ointment in children with moderate to severe AD. PATIENTS AND METHODS: Patients applied ointment daily to all affected body surface areas. The primary study endpoint was the percentage change in the modified Eczema Area and Severity Index (mEASI) between baseline and treatment end. RESULTS: Six hundred and twenty-four patients, aged 2-15 years, applied 0.03% tacrolimus ointment once daily (n = 207), twice daily (n = 210) or 1% HA twice daily (n = 207). By the end of treatment, application of 0.03% tacrolimus ointment both once or twice daily resulted in significantly greater median percentage decreases in mEASI (66.7% and 76.7%, respectively) compared with 1% HA (47.6%; P < 0.001). Furthermore, the median percentage decrease in mEASI was significantly greater for patients applying 0.03% tacrolimus twice daily compared with once daily (P = 0.007). Patients with severe AD benefited especially from twice daily application of 0.03% tacrolimus ointment compared with once daily application (P = 0.001). Transient mild to moderate skin burning occurred significantly more often in the 0.03% tacrolimus groups (P = 0.028) but resolved in most cases within 3-4 days. Laboratory parameters showed no clinically relevant changes. CONCLUSIONS: 0.03% tacrolimus ointment applied once or twice daily is significantly more efficacious than 1% HA in treating moderate-severe AD in children. Twice daily application of 0.03% tacrolimus ointment results in the greatest improvement in mEASI, and is especially effective in patients with severe baseline disease.

Atopic dermatitis management with tacrolimus ointment (Protopic).

Tacrolimus ointment is the first of a new class of non-steroidal topical immunomodulators indicated for the treatment of atopic dermatitis. Topical tacrolimus has been subject to an extensive clinical development program involving more than 16,000 patients. A clinical trial program, including vehicle-controlled studies, short- and long-term comparative studies and long-term safety studies, has investigated tacrolimus 0.1% and 0.03% ointment for the treatment of atopic dermatitis in adults and children aged 24 months and older. Tacrolimus monotherapy is rapidly effective, resulting in clinical improvements within three days of starting therapy, and produces a progressive increase in efficacy that is sustained during long-term treatment. Tacrolimus treats the signs and symptoms of atopic dermatitis, reduces the incidence of flares, and offers the potential for long-term disease control. No major safety concerns have been reported to date. Tacrolimus ointment is generally well tolerated, the primary adverse events being mild to moderate and transient application-site reactions: skin burning, pruritus and erythema. Tacrolimus ointment is a significant advance in dermatology and provides physicians with an alternative to conventional topical corticosteroid therapy.

Efficacy of sirolimus (rapamycin) administered concomitantly with a subtherapeutic dose of cyclosporin in the treatment of severe psoriasis: a randomized controlled trial.

BACKGROUND: The identification of a highly potent immunosuppressive/antiproliferative agent with an acceptable toxicity profile has long been a goal for the management of severe plaque psoriasis. OBJECTIVES: To investigate the efficacy and safety of sirolimus (Rapamune) for severe psoriasis when given alone or in association with cyclosporin. METHODS: In a randomized, double-blind, eight parallel group, pilot study in 24 out-patient centres in seven European countries, 150 patients, 18 years and older, with severe chronic plaque psoriasis were given sirolimus 0.5, 1.5 and 3.0 mg m(-2) daily for 8 weeks, either alone or in association with a subtherapeutic dose of cyclosporin (1.25 mg kg(-1) daily). Cyclosporin 5 mg kg(-1) daily was the positive control and cyclosporin 1.25 mg kg(-1) daily the negative control. The primary efficacy variable was the mean percentage reduction in Psoriasis Area and Severity Index (PASI). Safety assessments included monitoring of adverse events, clinical laboratory parameters and sirolimus/cyclosporin blood concentrations. RESULTS: The greatest mean percentage decreases in PASI were seen with cyclosporin 5.0 mg kg(-1) daily (70.5%) and with sirolimus 3.0 mg m(-2) daily + cyclosporin 1.25 mg kg(-1) daily (63.7%). Both groups demonstrated significantly better results than cyclosporin 1.25 mg kg(-1) daily (mean decrease 33.4%). Serum creatinine levels were significantly lower for groups with sirolimus alone and sirolimus plus reduced-dose cyclosporin when compared with cyclosporin 5.0 mg kg(-1) daily. Adverse events associated with sirolimus included thrombocytopenia (5%), hyperlipidaemia (9%), aphthous stomatitis (9%) and acne (13%), whereas adverse events associated with cyclosporin included hot flushes (12%), hyperlipidaemia (9%) and increased serum creatinine (9%). CONCLUSIONS: The concomitant administration of sirolimus with a subtherapeutic dose of cyclosporin in severe psoriasis may permit a reduction in their respective toxicities, notably cyclosporin-induced nephrotoxicity.

Comparison of cyclosporin and UVAB phototherapy for intermittent one-year treatment of atopic dermatitis.

Although cyclosporin is effective for the treatment of severe atopic dermatitis, phototherapy is the standard second-line treatment for this disease. An open, randomized, controlled, parallel-group study was conducted to compare the efficacy, influence on quality of life and safety of cyclosporin and UVAB phototherapy during 1 year of intermittent treatment of atopic dermatitis in adult patients. The main endpoints of the study were the number of days in remission and the influence on quality of life. Seventy-two patients were treated, 36 in each group. Cyclosporin produced significantly more days in remission than UVAB phototherapy during the 1-year study period. At the end of the study no difference between the 2 groups was noted in terms of quality of life. A significant increase in serum creatinine occurred in 2 patients and 7 patients developed mild or moderate hypertension during cyclosporin treatment. It can be concluded that intermittent cyclosporin seems to be more effective than UVAB and is reasonably safe for the treatment of atopic dermatitis over a 1-year treatment period.
