Combination therapy to treat moderate to severe psoriasis.

In patients with moderate-to-severe psoriasis, remission can be difficult to achieve and sustain. Both acutely acting and long-term maintenance agents are needed. Speed and efficiency of available monotherapies tend to be inversely proportional to safety. Combination, rotational, and sequential approaches are often more effective and safer than single-agent therapy. Combining agents with complementary adverse effect profiles is preferable. Apparent synergistic enhancement is seen with most paired combinations of the four major therapies: acitretin, phototherapy (ultraviolet B/psoralen plus ultraviolet A), cyclosporine, and methotrexate. Of those, only cyclosporine in combination with psoralen plus ultraviolet A is contraindicated because of increased cancer risk. Combinations of each of those major therapies with topical agents (retinoids, steroids, vitamin D derivatives, and others) have been used with varying efficacy and safety. The immunomodulators, hydroxyurea and thioguanine, have also shown some success in combination therapy. The new biologic agents with their novel modes of action and adverse effect profiles may prove to be important adjuncts in combination/rotational/sequential approaches. In some cases, monotherapy (with either systemic agents or phototherapy) adequately controls moderate to severe disease. A regimen using a single agent has the advantages of lower cost and greater adherence by the patient. For any number of reasons, however, including loss of efficacy, adverse effects, or cumulative or acute toxicity-and especially the inability to clear resistant lesions-a single modality will not be adequate. Using two or more therapies is thus the rule rather than the exception for most patients with moderate-to-severe psoriasis, but picking a combination that serves to balance safety and efficacy needs careful consideration, especially since no evidence-based treatment guidelines exist.

A 50% reduction in the Psoriasis Area and Severity Index (PASI 50) is a clinically significant endpoint in the assessment of psoriasis.

A 75% reduction in the Psoriasis Area and Severity Index (PASI) score (PASI 75) is the current benchmark of primary endpoints for most clinical trials of psoriasis. Many consider this endpoint to be too stringent as it places potentially useful therapies at risk of failing to demonstrate efficacy. We hypothesized that a 50% reduction in the PASI score (PASI 50) represents a meaningful change in a person's life and thus is a better primary endpoint. To test this hypothesis, we analyzed PASI scores, quality of life (QoL) data, and desired re-treatment scores from a number of clinical trials in addition to studying individual elements that make up the PASI. This analysis shows (1). the PASI score is not linearly reflective of psoriasis severity (eg, a reduction in area of 95% without a change in redness, scaliness, and induration translates to only a 66% reduction in PASI); conversely, a drop in erythema, scale, and induration from an average of 3 to 1 would not lead to a 75% reduction in PASI; (2). treatment with methotrexate, an effective psoriasis therapy, more frequently reaches PASI 50 than PASI 75 as evidenced by a recent open trial in which 63% of patients achieved PASI 50 versus 26% achieving PASI 75; (3). improvement in QoL exists at PASI 50, using the Dermatology Quality of Life Index, as documented in several recently completed large clinical trials; (4). patients achieving PASI 75 frequently defer therapy until they are well below PASI 50; a clinical trial where retreatment was patient initiated showed patients did not re-treat until their PASI dropped to an average of 20% improvement from baseline; and (5). effective, meaningful therapies are consistently differentiated from placebo at PASI 50 as evidenced by histologic and photographic parameters of clinical trials of alefacept, efalizumab, and etanercept. We conclude that PASI 50 equates to a clinically meaningful improvement in psoriasis and represents a discerning primary endpoint.

Infliximab induction therapy for patients with severe plaque-type psoriasis: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Tumor necrosis factor-alpha is a key mediator in the pathogenesis of psoriasis. Infliximab is a monoclonal antibody that specifically binds to tumor necrosis factor-alpha, blocking its biologic activity. OBJECTIVE: The purpose of this study was to access the efficacy and safety of infliximab induction therapy for patients with severe plaque psoriasis. METHODS: In this multicenter, double-blind, placebo-controlled trial, 249 patients with severe plaque psoriasis were randomly assigned to receive intravenous infusions of either 3 or 5 mg/kg of infliximab or placebo given at weeks 0, 2, and 6. The primary end point was the proportion of patients who achieved at least 75% improvement in Psoriasis Area and Severity Index score from baseline at week 10. At week 26, patients whose Physician Global Assessment indicated moderate or severe disease were eligible for a single intravenous infusion of their assigned treatment to assess the safety of retreatment after a 20-week, treatment-free interval. RESULTS: At week 10, 72% of patients treated with infliximab (3 mg/kg) and 88% of patients treated with infliximab (5 mg/kg) achieved a 75% or greater improvement from baseline in Psoriasis Area and Severity Index score compared with 6% of patients treated with placebo (P <.001). Improvement was observed in both infliximab groups as early as 2 weeks. Overall, 63%, 78%, and 79% of patients in the placebo, 3-, and 5-mg/kg groups, respectively, reported one or more adverse events. CONCLUSIONS: Infliximab treatment resulted in a rapid and significant improvement in the signs and symptoms of psoriasis. Infliximab was generally well tolerated.

Effect of a single course of isotretinoin therapy on bone mineral density in adolescent patients with severe, recalcitrant, nodular acne.

BACKGROUND: Adverse changes in bone have been reported for patients undergoing high-dose, long-term (several years) isotretinoin therapy for disorders of cornification. The effect of short-term (4-5 months) therapy at the lower dose recommended for acne on bone development in younger, growing adolescent (12-17 years) patients has not been well studied. OBJECTIVE: The purpose of the study was to evaluate the effect of a standard, single course of isotretinoin (Accutane) therapy on bone mineral density (BMD) of the lumbar spine and hip in adolescents ages 12 to 17 years with severe, recalcitrant, nodular acne. METHODS: In this open-label, multicenter study, 217 adolescents (81 girls) with severe, recalcitrant, nodular acne were enrolled and treated with isotretinoin twice daily with food at the recommended total dose of approximately 1 mg/kg for 16 to 20 weeks. BMD in the lumbar spine and hip was measured at baseline and at the end of therapy by dual energy radiograph absorptiometry. RESULTS: There was no clinically significant mean change in BMD measured at the lumbar spine (+1.4%, range: -4.9% to +12.3%) or total hip (-0.26%, range: -11.3% to +15.0%). Hyperostosis was not observed in any patient. Typical efficacy expected in the treatment of acne was observed. CONCLUSIONS: A 16- to 20-week course of isotretinoin treatment at the recommended dose for severe acne has no clinically significant effect on lumbar spine and total hip BMD in the adolescent (12-17 years) population.

Pimecrolimus cream 1% in the treatment of intertriginous psoriasis: a double-blind, randomized study.

BACKGROUND: Inverse psoriasis can be difficult to treat because of the high sensitivity of intertriginous areas to cutaneous side effects, such as irritation and striae. Pimecrolimus, a well-tolerated, nonatrophogenic, skin-selective inflammatory cytokine inhibitor, has been shown to be effective in the treatment of psoriasis when applied topically under occlusion. OBJECTIVE: This study evaluated the efficacy and safety of pimecrolimus cream 1% versus vehicle twice a day in the treatment of inverse psoriasis. Methods This was a double-blind, randomized, vehicle-controlled study in 57 patients with moderate to severe inverse psoriasis. Patients were evaluated using Investigator's Global Assessment of overall severity, Target Area Score, and Patient Self-Assessment. RESULTS: A significant between-group difference was observed early on, with 54% of the pimecrolimus group versus 21% of the vehicle group having an Investigator's Global Assessment score of 0 or 1 (clear or almost clear) at week 2 ( P = .0169). By week 8, 71% of the pimecrolimus group had an Investigator's Global Assessment score of 0 or 1. Change from baseline in Target Area Score was -2.4 (pimecrolimus group) compared with -0.7 (vehicle) at day 3 ( P < .0001). By week 8, 82% of patients using pimecrolimus scored their disease as well or completely controlled versus 41% of the vehicle group ( P = .0007). Adverse events were similar between groups. CONCLUSION: Pimecrolimus cream 1% is an effective treatment for inverse psoriasis with a rapid onset of action, and is safe and well-tolerated.

Practical considerations in future psoriasis therapies.

Exciting new therapies are becoming available that allow dermatologists and patients safe and effective alternatives to traditional psoriasis therapy. Because these new biologic drugs are parenterally administered, practical aspects of their integration into clinical practice must be addressed. This article offers guidelines for incorporating subcutaneous,intramuscular, and intravenous injectables into dermatology offices. Several tiers of psoriasis care are outlined to encourage individual physicians to choose the optimum level of service compatible with their individual practices.

Infliximab.

Infliximab is a chimeric monoclonal antibody that interferes with the actions of the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha). Clinical trials of infliximab have demonstrated a rapid and substantial response in patents with psoriasis and psoriatic arthritis, substantiating the role of TNF-alpha in the immunopathogenesis of psoriatic disease. This review summarizes the current data regarding the use of infliximab in treating psoriasis and psoriatic arthritis, as well as the safety data available from patients with other immune-mediated inflammatory disorders. Practical issues such as patient selection, monitoring, cost, and potential combination therapies are also discussed.

Efalizumab for patients with moderate to severe plaque psoriasis: a randomized controlled trial.

CONTEXT: Because T-cell interactions are involved in the pathophysiology of psoriasis, therapy with a T-cell modulator may have beneficial effects on psoriasis severity and health-related quality of life (HRQL). OBJECTIVE: To assess the efficacy and safety of efalizumab, a T-cell modulator, in patients with plaque psoriasis. DESIGN, SETTING, AND PATIENTS: Phase 3 randomized, double-blind, parallel-group, placebo-controlled trial involving 556 adult patients with stable, moderate to severe plaque psoriasis and conducted at 30 study centers in the United States and Canada between January and July 2002. INTERVENTIONS: Patients were randomly assigned in a 2:1 ratio to receive 12 weekly doses of subcutaneous efalizumab, 1 mg/kg (n = 369), or placebo equivalent (n = 187). MAIN OUTCOME MEASURES: At least 75% improvement on the Psoriasis Area and Severity Index (PASI-75); improvement on the overall Dermatology Life Quality Index (DLQI), Itching Visual Analog Scale (VAS), and Psoriasis Symptom Assessment (PSA) at week 12 vs baseline. RESULTS: Efalizumab-treated patients experienced significantly greater improvement on all end points than placebo-treated patients. Twenty-seven percent of efalizumab-treated patients achieved PASI-75 vs 4% of the placebo group ( P<.001). Efalizumab-treated patients exhibited significantly greater mean percentage improvement than placebo-treated patients on the overall DLQI (47% vs 14%; P<.001), Itching VAS (38% vs -0.2%; P<.001), and PSA frequency and severity subscales (48% vs 18% and 47% vs 17%, respectively; P<.001 for both) at the first assessment point. Efalizumab was safe and well tolerated, with primarily mild to moderate adverse events. CONCLUSION: In this 12-week study, efalizumab resulted in significant improvements in clinical end points, including physician-assessed and dermatology-specific patient-reported HRQL measures, in patients with moderate to severe plaque psoriasis.

A putative RUNX1 binding site variant between SLC9A3R1 and NAT9 is associated with susceptibility to psoriasis.

Psoriasis (OMIM 177900) is a chronic inflammatory skin disorder of unknown pathogenesis affecting approximately 2% of the Western population. It occurs more frequently in individuals with human immunodeficiency virus, and 20-30% of individuals with psoriasis have psoriatic arthritis. Psoriasis is associated with HLA class I alleles, and previous linkage analysis by our group identified a second psoriasis locus at 17q24-q25 (PSORS2; ref. 7). Linkage to this locus was confirmed with independent family sets. Additional loci have also been proposed to be associated with psoriasis. Here we describe two peaks of strong association with psoriasis on chromosome 17q25 separated by 6 Mb. Associated single-nucleotide polymorphisms (SNPs) in the proximal peak lie in or near SLC9A3R1 (also called EBP50 and NHERF1) and NAT9, a new member of the N-acetyltransferase family. SLC9A3R1 is a PDZ domain-containing phosphoprotein that associates with members of the ezrin-radixin-moesin family and is implicated in diverse aspects of epithelial membrane biology and immune synapse formation in T cells. The distal peak of association is in RAPTOR (p150 target of rapamycin (TOR)-scaffold protein containing WD-repeats). Expression of SLC9A3R1 is highest in the uppermost stratum Malpighi of psoriatic and normal skin and in inactive versus active T cells. A disease-associated SNP lying between SLC9A3R1 and NAT9 leads to loss of RUNX1 binding. This is the second example of loss of a RUNX1 binding site associated with susceptibility to an autoimmune disease. It also suggests defective regulation of SLC9A3R1 or NAT9 by RUNX1 as a susceptibility factor for psoriasis.

Novel mechanisms of T-cell and dendritic cell activation revealed by profiling of psoriasis on the 63,100-element oligonucleotide array.

A global picture of gene expression in the common immune-mediated skin disease, psoriasis, was obtained by interrogating the full set of Affymetrix GeneChips with psoriatic and control skin samples. We identified 1,338 genes with potential roles in psoriasis pathogenesis/maintenance and revealed many perturbed biological processes. A novel method for identifying transcription factor binding sites was also developed and applied to this dataset. Many of the identified sites are known to be involved in immune response and proliferation. An in-depth study of immune system genes revealed the presence of many regulating cytokines and chemokines within involved skin, and markers of dendritic cell (DC) activation in uninvolved skin. The combination of many CCR7+ T cells, DCs, and regulating chemokines in psoriatic lesions, together with the detection of DC activation markers in nonlesional skin, strongly suggests that the spatial organization of T cells and DCs could sustain chronic T-cell activation and persistence within focal skin regions.

Treatment of psoriasis with alefacept: correlation of clinical improvement with reductions of memory T-cell counts.

OBJECTIVE: To examine the relationship between the pharmacodynamic and antipsoriatic effects of alefacept, a biologic agent that targets CD4+ and CD8+ memory T cells. DESIGN: Randomized, double-blind, placebo-controlled study of 3 parallel groups. SETTING: Fifty-one study centers. PATIENTS: Five hundred fifty-three patients with chronic plaque psoriasis. INTERVENTIONS: Patients were randomized (1:1:1) to 1 of the following 3 cohorts: alefacept, 7.5 mg, in both courses (cohort 1); alefacept, 7.5 mg, in the first course and placebo in the second course (cohort 2); or placebo in the first course and alefacept, 7.5 mg, in the second course (cohort 3). In each course, alefacept or placebo was administered by intravenous bolus once weekly for 12 weeks, followed by 12 weeks of observation. MAIN OUTCOME MEASURES: Circulating lymphocyte levels and the Psoriasis Area Severity Index. RESULTS: One or 2 courses of alefacept reduced CD4+ and CD8+ memory T-cell counts, while sparing the naive population. At 12 weeks after the last dose of alefacept in courses 1 and 2, 88% and 83% of patients, respectively, had CD4+ cell counts greater than the lower limit of normal. In course 1, alefacept-treated patients with the largest decreases in memory T-cell counts experienced the greatest reductions in disease activity (P<.001). The duration of clinical benefit seemed to be longer among patients who had the greatest reduction in CD4+ and CD8+ memory T-cell counts. CONCLUSIONS: One or 2 courses of intravenous alefacept reduced circulating memory T-cell counts while sparing the naïve T-cell population. The reductions in memory T-cell counts were related to all measures of disease activity evaluated and the duration of response to therapy, suggesting that prolonged remissions of psoriasis can be attained with reduction of the pathogenic T-cell count.

Repeat courses of intravenous alefacept in patients with chronic plaque psoriasis provide consistent safety and efficacy.

BACKGROUND: Psoriasis is a chronic, relapsing skin disease that may require multiple treatment courses. Alefacept targets the memory T cells implicated in psoriasis pathogenesis. This open-label study evaluated the safety and tolerability, efficacy, and pharmacodynamics of repeat courses of alefacept in men and women with chronic plaque psoriasis. This article reports the interim results of this ongoing study. METHODS: Patients (n = 174) who participated in previous phase II studies of alefacept were included in this retreatment study. Intravenous alefacept (7.5 mg) was administered once weekly for 12 weeks followed by 12 weeks of observation. Initial and subsequent retreatment courses were only given when, in the opinion of the investigators, disease had returned and necessitated treatment; CD4+ T-cell counts had to be at or above the lower limit of normal. RESULTS: Adverse events were similar regardless of the retreatment course. No opportunistic infections, rebound of disease, or flares were reported. Low titers of anti-alefacept antibodies occurred in a few patients without related safety issues. Sixty-six per cent of patients achieved a >/= 50% reduction in the Psoriasis Area and Severity Index (PASI) at any time after the first dose of retreatment course 1. Patients who received two retreatment courses (n = 50) had consistent or improved responses after the second course; 64% and 68% of these patients achieved a >/= 50% PASI improvement at any time after the first dose of retreatment courses 1 and 2, respectively. Alefacept selectively reduced memory T cells without cumulative effects. CONCLUSIONS: Repeat courses of alefacept were well tolerated, and subsequent retreatment courses were at least as effective as the initial course of therapy.

Ciclopirox gel for seborrheic dermatitis of the scalp.

BACKGROUND: Seborrheic dermatitis is a common inflammatory skin disorder that usually occurs in patients with pre-existing seborrhea. The etiology of seborrheic dermatitis is uncertain. Typically, sites dense with sebaceous glands support growth of the lipophilic yeast Malassezia furfur. Ciclopirox (Loprox) gel is a hydroxypyridone, broad-spectrum antifungal agent proven effective against the yeast M. furfur. OBJECTIVE: A multicenter, randomized, double-blind, vehicle controlled study of 178 subjects evaluated the efficacy of ciclopirox gel in treating seborrheic dermatitis of the scalp. METHODS: One hundred and seventy-eight subjects were randomized to apply either ciclopirox gel 0.77% twice daily, or vehicle twice daily for 28 days. Subjects' signs and symptoms of severity (erythema, scaling, pruritus and burning) were rated on a scale of 0-3 (none to severe); for inclusion, a minimum score of 4, for the sum of the individual ratings was required. Efficacy evaluations were performed at baseline, days 4, 8, 15, 22, 29, and at end-point (final visit, up to day 33). The primary efficacy variable was clinical response assessed by a global improvement, based on a scale of 0-5 (100% clearance to flare of treatment area). Changes in signs/symptoms severity scores within the target lesion were also evaluated. RESULTS: Global evaluation scores demonstrated that significantly more ciclopirox-treated subjects achieved over 75% improvement compared with vehicle at days 22, 29, and endpoint (P < 0.01). Change-from-baseline mean score for total signs and symptoms was significantly greater in ciclopirox subjects compared with vehicle subjects at the same time points as above (P < 0.001), as well as day 15 (P < 0.01). Twenty-nine percent of subjects rated ciclopirox as having excellent cosmetic acceptability. There were only mild adverse events, with the most common being burning sensation in 13% of ciclopirox subjects and 9% of vehicle subjects. CONCLUSION: Ciclopirox gel is effective and safe in the treatment of seborrheic dermatitis of the scalp.

Ciclopirox gel in the treatment of patients with interdigital tinea pedis.

UNLABELLED: BACKGROUND Tinea pedis (athlete's foot) is the most common fungal infection in the general population. Ciclopirox, a broad-spectrum hydroxypyridone antifungal, has proven efficacy against the organisms commonly implicated in tinea pedis; Trichophyton rubrum, T.mentagrophytes and Epidermophyton floccosum. OBJECTIVE: Two multicenter, double-blind, clinical studies compared the efficacy and safety of ciclopirox gel with that of its vehicle base in subjects with moderate interdigital tinea pedis with or without plantar involvement. METHODS: Three hundred and seventy-four subjects were enrolled and randomized to one of two treatment groups: ciclopirox gel 0.77%, or ciclopirox gel vehicle, applied twice daily for 28 days, with a final visit up to day 50. The primary efficacy variable was Treatment Success defined as combined mycological cure and clinical improvement >/= 75%. Secondary measures of effectiveness were Global Clinical Response, Sign and Symptom Severity Scores, Mycological Evaluation (KOH examination and final culture result), Mycological Cure (negative KOH and negative final culture results) and Treatment Cure (combined clinical and mycological cure). RESULTS: At endpoint (final post-baseline visit), 60% of the ciclopirox subjects achieved treatment success compared to 6% of the vehicle subjects. At the same time point, 66% of ciclopirox subjects compared with 19% of vehicle subjects were either cleared or had excellent improvement. Pooled data showed that 85% of ciclopirox subjects were mycologically cured, compared to only 16% of vehicle subjects at day 43, 2 weeks post-treatment. CONCLUSIONS: Ciclopirox gel 0.77% applied twice daily for 4 weeks is an effective treatment of moderate interdigital tinea pedis due to T. rubrum, T. mentagrophytes and E. floccosum and is associated with a low incidence of minor adverse effects.

Case studies in severe psoriasis: A clinical strategy.

Individuals with moderate-to-severe psoriasis perceive that the disease exerts profound emotional, social and physical effects on their lives, and a significant percentage report that they do not consider their treatment sufficiently aggressive. A survey of individuals with a variety of chronic diseases reveals that those with psoriasis have the lowest estimation of their health-related quality of life, lower than that of patients with arthritis, congestive heart failure, chronic lung disease or depression. Although psoriasis can be treated effectively, many treatments are associated with long-term risks. Toxicity-sparing treatment strategies that include combination, rotational and sequential regimens can help to control moderate-to-severe psoriasis while reducing risk. Algorithms for the treatment of moderate-to-severe psoriasis detail possible options for specific types of psoriasis and for patients with specific needs. The purpose of the algorithms is to make optimum use of phototherapy, traditional cytotoxic and immunosuppressive agents, retinoids, and newer biologic agents.

Modulating T cell responses for the treatment of psoriasis: a focus on efalizumab.

An improved understanding regarding the pathophysiology of psoriasis, coupled with advances in molecular research, has prompted the development of targeted biologic treatments for patients with plaque psoriasis. T lymphocytes play an important role in initiating the immune system and the inflammatory responses that result in the development and maintenance of psoriatic plaques. Efalizumab (anti-CD11a, Raptiva; Genentech, Inc.) is a mAb that targets the T cell adhesion molecule, leukocyte function-associated antigen-1 (LFA-1). By binding to CD11a - the alpha-subunit of LFA-1 - LFA-1 is prevented from binding with its ligand, intercellular adhesion molecule-1 (ICAM-1). This inhibits various T cell processes believed to be important in the pathogenesis of psoriasis, including T cell activation, T cell adhesion to endothelial cells and T cell migration. Clinical trials demonstrate that efalizumab, given subcutaneously once-weekly, provides clinical benefit, including improved quality of life, in patients with moderate-to-severe plaque psoriasis. Efalizumab is associated with an early onset of action, with improvement noted as early as 14 days. Studies with extended treatment suggest that continuing efalizumab therapy is more beneficial in maintaining and improving responses. Relapse of psoriasis is usually seen within 60 - 70 days after discontinuation of therapy, and rebound in approximately 5% of patients (i.e., flare to > 125% of baseline) is noted. Efalizumab is associated with acute adverse events during the first and second injections, which decrease in incidence with each subsequent injection. Data indicate that efalizumab can be safely administered for extended periods of time. Given the efficacy, early onset of clinical benefit, the safety profile and the convenience of once-weekly subcutaneous home dosing, efalizumab offers an interesting new therapeutic option for the treatment of psoriasis and the potential for improved and potentially safer long-term, continuous 'maintenance' therapy.

Efficacy and safety of a new triple-combination agent for the treatment of facial melasma.

Treatment of melasma, a hyperpigmentation disorder, remains a challenge. The primary objective of two 8-week, multicenter, randomized, investigator-blind studies was to compare the efficacy and safety of a hydrophilic cream formulation containing tretinoin 0.05%, hydroquinone 4.0%, and fluocinolone acetonide 0.01% (RA+HQ+FA) with the dual-combination agents tretinoin plus hydroquinone (RA+HQ), tretinoin plus fluocinolone acetonide (RA+FA), and hydroquinone plus fluocinolone acetonide (HQ+FA). All agents had the same drug concentration and vehicle. A total of 641 adult patients, predominantly female, with moderate to severe melasma and Fitzpatrick skin types I through IV, were randomized to the various treatment groups. Due to the similarity of the study designs, the results of the 2 studies were combined and are reported here. The primary efficacy analysis involved the proportion of intent-to-treat patients in each treatment group whose condition had completely cleared by week 8. The results of the combined clinical trials demonstrated that significantly more of the patients treated with RA+HQ+FA (26.1%) experienced complete clearing compared with the other treatment groups (4.6%) at the end of week 8 (P<.0001). In addition, at week 8, a 75% reduction in melasma/pigmentation was observed in more than 70% of patients treated with RA+HQ+FA compared with 30% in patients treated with the dual-combination agents. The most common adverse reactions seen with all treatment groups were erythema, skin peeling, burning, and/or stinging sensation. The majority of treatment-related adverse events were of mild severity.
