Expert Recommendations on Use of Topical Therapeutics for Vitiligo in Pediatric, Adolescent, and Young Adult Patients

Importance

Evidence-based recommendations for the treatment of vitiligo in pediatric, adolescent, and young adult patients in the US are needed.

Objective

To develop evidence- and consensus-based expert recommendations on the diagnosis and treatment of vitiligo in young patients.

Evidence Review

A process was developed to produce consensus recommendations addressing questions regarding pediatric vitiligo. A librarian-conducted literature review was performed using articles that met the inclusion criteria: published in English, containing primary data (including meta-analysis) and pediatric-specific data, and analysis of 6 or more patients. Included articles were graded by the Strength of Recommendation Taxonomy criteria and Oxford Centre for Evidence-based Medicine's Levels of Evidence and Grades of Recommendation. Research questions were reviewed on May 9, 2022, through a video conference. One month after the conference, participants participated in an online survey documenting their level of agreement with the generated statements, using a 5-point Likert scale.

Findings

Articles on topical corticosteroids and/or topical calcineurin inhibitors (n = 50), topical Janus kinase inhibitors (n = 5), pseudocatalase (n = 2), and microdermabrasion (n = 2) met inclusion criteria. Forty-two recommendations were made on the diagnosis of vitiligo and optimal topical therapeutics, with 33 recommendations obtaining a 70% or greater composite agreement and strong agreement. Topical calcineurin inhibitors twice daily, topical corticosteroids with time limitation due to atrophy risk, and topical ruxolitinib, 1.5%, cream-used off-label for patients younger than 12 years and limited to nonsegmental vitiligo-were identified as evidence-based first-line therapies in the management of pediatric and adolescent patients, with specific guidance on age-based data, minimum therapeutic trial of 6 months or greater, prolonged therapy to prevent recurrence, and the positive benefit of coordinated use of UV therapeutic sources.

Conclusions and Relevance

Evidence supports the use of topical calcineurin inhibitors, topical corticosteroids, and topical Janus kinase inhibitors as effective therapeutics for vitiligo in pediatric, adolescent, and young adult patients, with specific decisions on choice of agent based on factors such as site location, body surface area, and age.

Bimekizumab safety in patients with moderate-to-severe plaque psoriasis: pooled data from up to 3 years of treatment in randomized phase III trials

BACKGROUND

Patients with psoriasis require long-term management; therefore, understanding the long-term safety of new treatments, such as bimekizumab (BKZ), is crucial.

OBJECTIVES

To evaluate BKZ's 3-year safety profile in patients with moderate-to-severe plaque psoriasis.

METHODS

Three years of safety data were pooled from three phase III trials (BE VIVID, BE READY and BE SURE) and their ongoing open-label extension (BE BRIGHT). Treatment-emergent adverse events (TEAEs) are reported using exposure-adjusted incidence rates (EAIRs) per 100 patient-years (PY).

RESULTS

In total, 1495 patients received at least one BKZ dose; total BKZ exposure was 3876.4 PY. The overall EAIR of TEAEs was 175.5/100 PY and decreased with longer exposure to BKZ. The most commonly reported TEAEs were nasopharyngitis, oral candidiasis and upper respiratory tract infection (EAIRs of 15.0/100 PY, 10.1/100 PY and 6.5/100 PY, respectively); 99.3% of oral candidiasis events were mild or moderate in severity, none were serious and few led to discontinuation. EAIRs of other TEAEs of interest were low, including serious infections (1.2/100 PY), adjudicated inflammatory bowel disease (0.2/100 PY) and laboratory elevations in aspartate aminotransferase or alanine aminotransferase (> 5 × upper limit of normal: 0.6/100 PY).

CONCLUSIONS

In these analyses pooled across 3 years, no new safety signals were observed with longer exposure to BKZ. The vast majority of oral candidiasis events were mild or moderate in severity, as reported previously.

Lebrikizumab improved itch and reduced the extent of itch interference on sleep in patients with moderate-to-severe atopic dermatitis: two randomized, placebo-controlled, phase III trials

Itch and sleep loss due to itch are prevalent symptoms of moderate-to-severe atopic dermatitis, significantly impairing patients’ quality of life and wellbeing. First-line topical therapy is insufficient for most patients and there is an unmet need for effective treatments that provide symptom relief and quality of life improvement. In two randomized, placebo-controlled, phase III trials, significantly more patients treated with the novel monoclonal antibody lebrikizumab had ≥ 3-point improvement in Pruritus Numeric Rating Scale by week 16 vs. patients treated with placebo. In addition, significantly more patients treated with lebrikizumab achieved ≥ 1-point improvement in Sleep-Loss Scale score by week 16 vs. placebo. Onset of itch relief was rapid, occurring within the first few days of treatment.

Reliability and agreement testing of a new automated measurement method to determine facial vitiligo extent using standardized ultraviolet images and a dedicated algorithm

BACKGROUND

Facial repigmentation is the primary outcome measure for most vitiligo trials. The Facial Vitiligo Area Scoring Index (F-VASI) score is often chosen as the primary outcome measure to assess the efficacy of treatments for facial vitiligo. Although useful, this scoring system remains subjective and has several limitations.

OBJECTIVES

To assess the agreement and reliability of an algorithmic method to measure the percentage depigmentation of vitiligo on the face.

METHODS

We developed a dedicated algorithm called Vitil-IA® to assess depigmentation on standardized facial ultraviolet (UV) pictures. We then conducted a cross-sectional study using the framework of the ERASE trial (NCT04843059) in 22 consecutive patients attending a tertiary care centre for vitiligo. Depigmentation was analysed before any treatment and, for 7 of them, after 3 and 6 months of narrowband UVB treatment combined with 16 mg methylprednisolone, both used twice weekly. Interoperator and interacquisition repeatability measures were assessed for the algorithm. The results of the algorithmic measurement were then compared with the F-VASI and the percentage of depigmented skin scores assessed by 13 raters, including 7 experts in the grading of vitiligo lesions.

RESULTS

Thirty-one sets of pictures were analysed with the algorithmic method. Internal validation showed excellent reproducibility, with a variation of < 3%. The percentage of depigmentation assessed by the system showed high agreement with the percentage of depigmentation assessed by raters [mean error (ME) -11.94 and mean absolute error (MAE) 12.71 for the nonexpert group; ME 0.43 and MAE 5.57 for the expert group]. The intraclass correlation coefficient (ICC) for F-VASI was 0.45 [95% confidence interval (CI) 0.29-0.62] and 0.52 (95% CI 0.37-0.68) for nonexperts and experts, respectively. When the results were analysed separately for homogeneous and heterogeneous depigmentation, the ICC for homogeneous depigmentation was 0.47 (95% CI 0.31-0.77) and 0.85 (95% CI 0.72-0.94) for nonexperts and experts, respectively. When grading heterogeneous depigmentation, the ICC was 0.19 (95% CI 0.05-0.43) and 0.38 (95% CI 0.20-0.62) for nonexperts and experts, respectively.

CONCLUSIONS

We demonstrated that the Vitil-IA algorithm provides a reliable assessment of facial involvement in vitiligo. The study underlines the limitations of the F-VASI score when performed by nonexperts for homogeneous vitiligo depigmentation, and in all raters when depigmentation is heterogeneous.

Baseline Levels of Circulating Inflammatory Biomarkers Stratify Patients with Vitiligo Who Significantly Repigment after Treatment with Ruxolitinib Cream

BACKGROUND

Efficacy of ruxolitinib cream, a topical Jak1/Jak2 inhibitor, was demonstrated in a phase 2 trial in patients with vitiligo.

OBJECTIVE

This study aimed to characterize circulating inflammatory biomarker profiles in patients who demonstrated ≥50% improvement in facial Vitiligo Area Scoring Index scores by week 24 (group 1) and those who did not (group 2).

DESIGN

This was a posthoc analysis of a multicenter, randomized, double-blind, vehicle-controlled, phase 2 study in which screening was conducted between June 7, 2017 and March 21, 2018.

POPULATION

Patients aged between 18 and 75 years with vitiligo, including depigmentation affecting ≥0.5% of body surface area on the face and ≥3% of body surface area on nonfacial areas, were eligible.

INTERVENTION

Patients applied 1.5% ruxolitinib cream to lesions once or twice daily for 52 weeks.

MAIN OUTCOMES AND MEASURES

Patients were grouped by achievement of ≥50% improvement in facial Vitiligo Area Scoring Index at week 24. Proteomic analysis was performed on baseline serum samples.

RESULTS

Mean ± standard error facial Vitiligo Area Scoring Index in group 1 (n = 30) versus group 2 (n = 27) improved by 79.9 ± 4.0% versus 1.1 ± 7.3% and 91.9 ± 1.5% versus 25.1 ± 13.4% at weeks 24 and 52, respectively. Broad proteomic analysis revealed 76 proteins (of 1,104 tested) that were differentially expressed between groups 1 and 2 at baseline (P < 0.05). Ten distinct proteins were upregulated in group 1; 64 were elevated in group 2.

CONCLUSION

This analysis identified potential differences between patients who achieved ≥50% improvement in facial Vitiligo Area Scoring Index at 24 weeks and those who did not that require deeper scientific interrogation and may be important in stratifying therapeutic benefit for patients with vitiligo.

TRIAL REGISTRATION

The original study was registered at ClinicalTrials.gov, NCT03099304.

Worldwide expert recommendations for the diagnosis and management of vitiligo: Position statement from the International Vitiligo Task Force Part 1: towards a new management algorithm

BACKGROUND

The treatment of vitiligo can be challenging and depends on several factors such as the subtype, disease activity, vitiligo extent, and treatment goals. Vitiligo usually requires a long-term approach. To improve the management of vitiligo worldwide, a clear and up-to-date guide based on international consensus with uniform stepwise recommendations is needed.

OBJECTIVES

To reach an international consensus on the nomenclature and to develop a management algorithm for the diagnosis, assessment, and treatment of vitiligo.

METHODS

In this consensus statement, a consortium of 42 international vitiligo experts and four patient representatives participated in online and live meetings to develop a consensus management strategy for vitiligo. At least two vitiligo experts summarized the evidence of topics included in the algorithms. A survey was utilized to resolve remaining issues among a core group of eight experts. Subsequently, the unanimous recommendations were finalized and validated based on further input from the entire group during two live meetings.

RESULTS

The algorithms highlight the importance of shared decision-making. Dermatologists are encouraged to provide patients with detailed explanations of the prognosis and expected therapeutic outcomes based on clinical examination. The treatment goal should be discussed and clearly emphasized to patients given the different approaches for disease stabilization and repigmentation. The evaluation of disease activity remains a cornerstone in the tailor-made approach to vitiligo patients.

CONCLUSIONS

These new treatment algorithms are intended to guide clinical decision-making in clinical practice. Promising novel therapies for vitiligo are on the horizon, further highlighting the need for reliable outcome measurement instruments and greater emphasis on shared decision-making.

Worldwide expert recommendations for the diagnosis and management of vitiligo: Position statement from the international Vitiligo Task Force-Part 2: Specific treatment recommendations

BACKGROUND

The treatment of vitiligo can be challenging. Up-to-date agreed consensus recommendations on the use of topical and systemic therapies to facilitate the clinical management of vitiligo are currently lacking.

OBJECTIVES

To develop internationally agreed-upon expert-based recommendations for the treatment of vitiligo.

METHODS

In this consensus statement, a consortium of 42 international vitiligo experts and four patient representatives participated in different online and live meetings to develop a consensus management strategy for vitiligo. At least two vitiligo experts summarized the evidence for different topics included in the algorithms. A survey was then given to a core group of eight experts to resolve the remaining issues. Subsequently, the recommendations were finalized and validated based on further input from the entire group during two live meetings.

RESULTS

The recommendations provided summarize the latest evidence regarding the use of topical therapies (steroids, calcineurin inhibitors and Jak-inhibitors) and systemic therapies, including steroids and other systemic immunomodulating or antioxidant agents. The different modalities of phototherapies (NB-UVB, photochemotherapy, excimer devices and home phototherapy), which are often combined with other therapies, are also summarized. Interventional approaches as well as depigmentation strategies are presented for specific indications. Finally, the status of innovative and targeted therapies under development is discussed.

CONCLUSIONS

This international consensus statement culminated in expert-based clinical practice recommendations for the treatment of vitiligo. The development of new therapies is ongoing in vitiligo, and this will likely improve the future management of vitiligo, a disease that still has many unmet needs.

Real-World Treatment Patterns in Patients with Vitiligo in the United States

INTRODUCTION

Vitiligo is an autoimmune disorder resulting in skin depigmentation, with limited approved treatment options. This study evaluated medication utilization and treatment patterns among patients in the first year following vitiligo diagnosis.

METHODS

This retrospective analysis of claims data from the Merative® MarketScan Research Databases included patients aged ≥ 12 years newly diagnosed with vitiligo. Patients were identified between October 1, 2016, and April 30, 2021, and had ≥ 12 months of continuous enrollment pre- and post-vitiligo diagnosis. Medication use, treatment line of therapy, time to and number of medication claims, and length of therapy were reported in the 12 months post-vitiligo diagnosis. Results are reported separately for treatment initiators post-vitiligo diagnosis, patients with moderate-to-severe vitiligo, and adolescents (aged 12-17 years).

RESULTS

A total of 19,335 patients were included in the analysis, with half (N = 9648, 49.9%) not receiving any treatment during the 12-month follow-up. Switching was minimal among treatment initiators (N = 5845) in the 12 months post-vitiligo diagnosis, with the most frequent first-line treatments being high-potency topical corticosteroids (25.4%), oral corticosteroids (23.1%), and topical calcineurin inhibitors (TCI, 14.7%). Adolescents initiating treatment (N = 486) most frequently received TCI (30.9%) as first-line therapy. Patients with moderate-to-severe vitiligo (N = 3462) were very likely to receive treatment during follow-up, with only 1.5% not receiving treatment. Among patients with no vitiligo treatment prior to diagnosis, time to first medication claim ranged from 51.9 days (standard deviation [SD], 84.0) for TCI to 178.6 days (SD 116.0) for systemic immunosuppressants; mean total days supplied ranged from 14.4 days (SD 27.1) for oral corticosteroids to 121.0 (SD 114.0) for immunosuppressants.

CONCLUSION

In this real-world study, a high proportion of patients did not receive any treatment. Among those receiving treatment, most were unlikely to switch or use a combination of treatments within the first year of vitiligo diagnosis.

Open-Label Phase 2 Pilot Study of Oral Tofacitinib in Adult Subjects With Discoid Lupus Erythematosus (DLE)

CITATION

Efficacy and safety of lebrikizumab in moderate-to-severe atopic dermatitis: 52-week results of two randomized double-blinded placebo-controlled phase III trials

BACKGROUND

Lebrikizumab is a novel, high-affinity monoclonal antibody that selectively binds to interleukin (IL)-13.

OBJECTIVES

To evaluate the efficacy and safety of lebrikizumab monotherapy in adolescent and adult patients with moderate-to-severe atopic dermatitis (AD) over 52 weeks of treatment in ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967).

METHODS

Patients who responded to lebrikizumab 250 mg every 2 weeks (Q2W) at the end of the 16-week induction period were re-randomized 2 : 2 : 1 to receive lebrikizumab Q2W, lebrikizumab 250 mg every 4 weeks (Q4W) or placebo Q2W (lebrikizumab withdrawal) for 36 additional weeks. Response at week 16 was defined as achieving a 75% reduction in Eczema Area Severity Index (EASI 75) or an Investigator's Global Assessment (IGA) of 0 or 1, with a ≥ 2-point improvement and no rescue medication use. Multiple imputation was used to handle missing data. Intermittent use of topical therapy was permitted during the maintenance period.

RESULTS

After 52 weeks, an IGA of 0 or 1 with a ≥ 2 point improvement was maintained by 71.2% of patients treated with lebrikizumab Q2W, 76.9% of patients treated with lebrikizumab Q4W and 47.9% of patients in the lebrikizumab withdrawal arm. EASI 75 was maintained by 78.4% of patients treated with lebrikizumab Q2W, 81.7% of patients treated with lebrikizumab Q4W and 66.4% of patients in the lebrikizumab withdrawal arm at week 52. Across treatment arms, proportions of patients using any rescue therapy were 14.0% (ADvocate1) and 16.4% (ADvocate2). During the combined induction and maintenance periods of ADvocate1 and ADvocate2, 63.0% of lebrikizumab-treated patients reported any treatment emergent adverse event, with most events (93.1%) being mild or moderate in severity.

CONCLUSIONS

After a 16-week induction period with lebrikizumab Q2W, lebrikizumab Q2W and Q4W maintained similar improvement of the signs and symptoms of moderate-to-severe AD, with a safety profile consistent with previously published data.

A review of the vitiligo literature to standardize the expression of disease severity

The literature on vitiligo is extremely heterogeneous with limited standardization in vitiligo disease severity reporting. The IDEOM Vitiligo Workgroup initiated a project to develop an improved understanding of clinical reporting of vitiligo severity and extent. A medical librarian-developed literature review identified 51 English-language clinical trials treating vitiligo topically using topical corticosteroids or topical tacrolimus that included adult and paediatric patients, with 10 or more patients. Grading of studies was performed using SORT criteria. The grading systems used included three studies reporting overall improvement: one as absolute Improvement vs. did not improve (B2), one as marked improvement (C3) and one as improvement, no change or worse (A2). Severity was reported as straight body surface area scoring (BSA) in five trials with grades of (A1, A1, B1, C2 and C3), and two via photography and mapping (A1, A2). Many studies report success as meeting the metric of 50% improvement or clearance (C3). Kanwar et al. further subdivides this into 50% to &lt;75% or &gt;75% (C3). Three studies add the complete clearance metric (A1, A1, B1), with some adding worsening categories. Most studies create a grading system including G0- no change (A1, A1, A2, A2&lt; B2, B2, B3, B3), G1- 1–25%, G2- 26–50%, G3- 51–75%, G4- 75–99% (one study by Lepe et al. reports this as &gt;75%) and G5- 100% re-pigmentation [Bae et al. (C2) report these numbers as 0, 1–24%, 25–49%, 50–74%, 75–99%, 100%]. Variations in response include the meta-analysis by Lee et al. reporting &gt;25%, &gt;50% and &gt;75% re-pigmentation and the combination of G0 and G1 as &lt; or = 25% re-pigmentation, considered a failure (A1, A1, A2. B2, C3, C3, C3). Koopmans-VanDorp (B2) and Kandil (B2) break down re-pigmentation as none, beginning (&lt;25%), good (25–90%) or complete or almost complete (90–100%) or spontaneous re-pigmentation. Success can be defined as G3–G5 or G4–G5. Kathuria classifies &lt;50% as failure (A1). Hu and Farajzadeh (A2) classify &gt;50% as success, Bae (C2) classifies &gt;75% and Kumari (B2) as &gt;90% improvement. Majid further subdivides the score into six subdivisions (A1). Abd-Elazim (A2) reports VASI and Baldo reports DLQI. Sach (C1) and Batchelor (A1) use the vitiligo noticeability scale Baldo, with target patches reported as ‘a lot less noticeable’ or ‘no longer noticeable’ being successful. Ibrahim (A2) uses Patient-Expressed Satisfaction, reporting ‘not satisfied’, ‘slightly satisfied’, ‘satisfied’ or ‘very satisfied’. Batchelor (A1) report percentage re-pigmentation, onset and maintenance of response, treatment burden, QoL, side effects and cost-effectiveness. Body surface area total and quartiles of improvement are the most commonly reported metrics in studies with high-level evidence. The addition of categories of no improvement, complete clearance, spontaneous improvement and worsening appears to enhance information collection. Collection of data using photographs or computer-assisted BSA monitoring enhances data reproducibility. Using 50%, 75% and 90% as thresholds for success appears to be standardized, with a rarer inclusion of 100%. Validated scores like VASI represent a validated alternative collection method, which can be modified to address the 50%, 75% and 90% thresholds. Quality of life has not per se been correlated to clinical response to topical therapeutics, and current scores including patient expression of satisfaction, vitiligo noticeability and satisfaction are not known to reflect topical response at this time.

Vitiligo evidence-based expert consensus recommendations for paediatric and adolescent patients: part I—topical therapeutics

No United States paradigm for the treatment of paediatric, adolescent and young adult vitiligo has been developed. To develop evidence and consensus-based expert opinion to promote therapeutic consistency for the diagnosis and treatment of vitiligo. An IRB-exempted process was developed to produce consensus recommendations based on literature review and SORT criteria. Research questions were reviewed on 9 May 2022 in a video-based conference. Forty-two recommendations were made on the diagnosis of vitiligo (5) and optimal topical therapeutics (37). Topical calcineurin inhibitors, topical corticosteroids and topical ruxolitinib 1·5% cream were all identified as potential first-line therapies in the management of paediatric and adolescent patients with specific guidance on age-based data, frequency of application, minimum length of the therapeutic trial and coordinated usage of ultraviolet light therapy. The literature on paediatric and adolescent vitiligo has a heterogeneous methodology and lack of patient-reported outcomes. Children with vitiligo may be effectively managed with a variety of topical agents as first- and second-line therapy. Evidence supports the utility of topical calcineurin inhibitors, topical corticosteroids and topical JAK inhibitors, with limitations based on factors such as location, body surface area and age.

Efficacy and safety of ruxolitinib cream for the treatment of vitiligo by patient demographics and baseline clinical characteristics: Week 52 pooled subgroup analysis from two randomized phase 3 studies

Vitiligo is a chronic autoimmune disease that targets melanocytes, causing skin depigmentation. Disease pathogenesis is largely regulated by interferon-γ activation of the Janus kinase (JAK) signalling pathway. A cream formulation of the JAK1/JAK2 inhibitor ruxolitinib demonstrated substantial re-pigmentation in two randomized, double-blind, vehicle-controlled phase 3 studies of adults and adolescents with vitiligo (TruE-V1 and TruE-V2). Pooled 52-week efficacy and safety data based on baseline demographics and clinical characteristics from the TruE-V studies are analysed and reported here. TruE-V1 (NCT04052425) and TruE-V2 (NCT04057573) were conducted in North America and Europe. Patients ≥ 12 years old diagnosed with nonsegmental vitiligo (NSV) with depigmentation covering ≤ 10% total body surface area (BSA), including facial and total Vitiligo Area Scoring Index (F-VASI/T-VASI) scores ≥ 0·5/≥ 3, were eligible for enrolment. Patients were randomized 2 : 1 to twice-daily 1·5% ruxolitinib cream or vehicle for 24 weeks, after which all patients could apply 1·5% ruxolitinib cream through Week 52 (open-label extension). At Week 52, patients who achieved ≥ 75% improvement from baseline in F-VASI (F-VASI75) were evaluated by sex, age group, Fitzpatrick skin type, facial BSA (F-BSA), investigator-assessed disease stability and previous therapy. Safety and tolerability were also assessed. Week 52 data are reported as observed. In total, 674 patients were randomized in the TRuE-V studies (ruxolitinib cream, n = 450; vehicle, n = 224); 673 and 661 patients were included in the safety and efficacy analyses, respectively, and 569 patients continued in the open-label extension (ruxolitinib cream from Day 1, n = 385; crossover from vehicle, n = 184). Mean (SD) age at baseline was 39·5 (15·1) years, and 27·9% of patients had Fitzpatrick skin types IV–VI. Baseline mean F-VASI and T-VASI values were 0·92 and 6·69, respectively. At Week 52, 50·3% of patients who applied ruxolitinib cream from Day 1 achieved F-VASI75. Efficacy by F-VASI75 response was identified in all demographic and clinical characteristic subgroups. Substantive F-VASI75 responses were seen for men [(n = 149), 43·6%] and women [(n = 201), 55·2%], and all age groups [12–17 years (n = 50), 48·0%; 18–64 years (n = 275), 52·0%; ≥ 65 years (n = 25), 36·0%]. F-VASI75 responses were also generally consistent based on skin type [I–III (n = 249), 47·4%; IV–VI (n = 101), 57·4%], F-BSA [&lt;1·5% (n = 283), 49·1%; ≥ 1·5% (n = 67), 55·2%], investigator-assessed disease stability [stable (n = 257), 49·4%; progressive (n = 93), 52·7%] and previous therapy [topical corticosteroids (n = 110), 50·9%; topical calcineurin inhibitors (n = 126), 49·2%; phototherapy (n = 113), 54·0%]. Treatment-related adverse events (AEs) occurred in 13·7% of patients who applied ruxolitinib cream at any time during the study, with generally similar rates among demographic subgroups for patients who applied ruxolitinib cream. Adolescent and adult patients with NSV applying ruxolitinib cream achieved efficacy per F-VASI75 at Week 52 regardless of baseline demographics or clinical characteristics. Ruxolitinib cream was well tolerated, and the incidence of treatment-related AEs was similar across subgroups.

IDEOM vitiligo work group: an update on our first year

The new Vitiligo Work Group of IDEOM was created in October 2021 and met at the annual IDEOM meetings of 2021 and 2022. The mission of the workgroup is to develop core outcome measures in vitiligo that meet three criteria: to meet the needs of stakeholders of all types, to be validated for clinical trials and studies, and to be used in all age groups of patients. The Vitiligo Work Group met November 2021 and June 2022, yielding a list of 10 potential core domains for voting. Voting was conducted at the Annual Meeting of IDEOM on 18 June 2022. Voting members of IDEOM included 23 dermatologists, 1 rheumatologist, 3 dermatologists and rheumatologists, 11 industry partners, 9 patients, 8 patient association representatives and 15 researchers. Core domains meeting 75% consensus threshold included: health-related quality of life (95·35%), extent of depigmentation (93·632%), treatment satisfaction including treatment burden (92·86%), location (83·67%), colour matching (82·69%) and maintenance of pigmentation (76·47%). Two domains met 50% threshold including primary diagnosis/comorbidities (59·62%) and trajectory of disease/stabilization (57·45%) and one domain, itch, failed to reach a consensus (38·46%). Using an approach of inclusion of stakeholders from all walks of life, six core domains reached a consensus for inclusion, two achieved partial consensus but required revision to break down the elements (e.g. primary diagnosis and comorbidities should be separated) and itch failed to achieve inclusion. The group continues to work on its core domains set using a broad range of stakeholders to produce a practical set of domains that are of importance to all stakeholders.

Effect of ruxolitinib cream on achievement of VASI50 by body region: Week 52 pooled analysis of the TRuE-V phase 3 studies

Vitiligo is a chronic inflammatory autoimmune disease that targets melanocytes, causing skin de-pigmentation. A cream formulation of the Janus kinase (JAK) 1/JAK2 inhibitor, ruxolitinib demonstrated substantial re-pigmentation in a phase 2 study in adults with vitiligo. In two multinational, randomized, double-blind, vehicle-controlled phase 3 studies of adults and adolescents with vitiligo (TRuE-V1, NCT04052425; TRuE-V2, NCT04057573), ruxolitinib cream was superior to vehicle at Week 24 in the primary and all key secondary endpoints. Pooled results on achievement of ≥ 50% improvement in the Vitiligo Area Scoring Index (VASI50) by body region in TRuE-V1/TRuE-V2 were analysed and are reported herein. Patients ≥ 12 years old with nonsegmental vitiligo (NSV) with de-pigmentation covering ≤ 10% total body surface area, including a total VASI (T-VASI) score ≥ 3, were eligible for enrolment. Patients were randomized 2 : 1 to twice-daily 1·5% ruxolitinib cream or vehicle for 24 weeks, after which all patients could apply twice-daily 1·5% ruxolitinib cream through Week 52 (open-label extension). The percentage of patients achieving VASI50 was calculated for each body region [head and neck (not including face), hands, upper extremities, trunk (including genitals), lower extremities, feet] and total body (excluding face). In total, 674 patients were randomized in the TRuE-V studies (ruxolitinib cream, n = 450; vehicle, n = 224); 661 patients were included in the efficacy analysis (1 site excluded for data quality) and 569 continued in the open-label extension (ruxolitinib cream from Day 1, n = 385; crossover from vehicle, n = 184). At Week 12, more patients who applied 1·5% ruxolitinib cream vs. vehicle achieved VASI50 in the head and neck (28·3% vs. 19·8%), upper extremities (14·1% vs. 11·0%), trunk (15·5% vs. 12·9%) and lower extremities (15·1% vs. 10·9%). At Week 24, more patients who applied 1·5% ruxolitinib cream vs. vehicle achieved VASI50 regardless of body region [head and neck, 45·3% vs. 23·8%; hands, 24·9% vs. 14·4%; upper extremities, 33·2% vs. 8·2%; trunk, 26·4% vs. 12·3%; lower extremities, 29·5% vs. 12·2%; feet, 18·5% vs. 12·5%; total body (excluding face), 20·8% vs. 6·9%]. Similarly at Week 52 more patients who applied ruxolitinib cream from Day 1 achieved VASI50 than those who switched over from vehicle after Week 24 (head and neck, 68·1% vs. 51·0%; hands, 38·2% vs. 29·2%; upper extremities, 56·7% vs. 34·9%; trunk, 48·4% vs. 25·4%; lower extremities, 54·5% vs. 32·3%; feet, 29·3% vs. 22·5%; total body [excluding face], 47·7% vs. 23·3%). Attainment of VASI50 at Week 52 among crossover patients (i.e. after 28 weeks of ruxolitinib cream) was consistent with Week 24 data in patients who applied ruxolitinib cream from Day 1. Adolescents and adults with NSV applying ruxolitinib cream achieved VASI50 in higher percentages compared with vehicle at Week 12 in the head and neck, upper extremities, trunk and lower extremities and at Week 24, regardless of the body region involved. The percentage of patients who achieved VASI50 increased through Week 52, including among patients who switched over from vehicle to ruxolitinib cream after Week 24. In summary, ruxolitinib cream produced a clinically meaningful re-pigmentation of all body regions (including hands and feet that are notoriously difficult to re-pigment) in TRuE-V1/TruE-V2 through Week 52, including among patients who switched over to ruxolitinib cream from vehicle after Week 24.

A Potential Alternative Treatment for Vitiligo: An Observational Study on Tacrolimus 0.3% Lotion

Vitiligo is a complex multifactorial disorder of depigmentation affecting 0.5 to 2% of the world's population without specific gender or racial prevalence.1 Though no treatments are FDA approved to repigment vitiligo, topical medications along with phototherapy alone or in combination remain the mainstay of therapy. While Janus Kinase inhibitors and other agents are in development, current topical options are mainly limited to steroid formulations of various potencies or immunomodulatory steroid-sparing agents such as tacrolimus 0.03% or 0.1%.

Two Phase 3, Randomized, Controlled Trials of Ruxolitinib Cream for Vitiligo

BACKGROUND

Vitiligo is a chronic autoimmune disease that causes skin depigmentation. A cream formulation of ruxolitinib (an inhibitor of Janus kinase 1 and 2) resulted in repigmentation in a phase 2 trial involving adults with vitiligo.

METHODS

We conducted two phase 3, double-blind, vehicle-controlled trials (Topical Ruxolitinib Evaluation in Vitiligo Study 1 [TRuE-V1] and 2 [TRuE-V2]) in North America and Europe that involved patients 12 years of age or older who had nonsegmental vitiligo with depigmentation covering 10% or less of total body-surface area. Patients were randomly assigned in a 2:1 ratio to apply 1.5% ruxolitinib cream or vehicle control twice daily for 24 weeks to all vitiligo areas on the face and body, after which all patients could apply 1.5% ruxolitinib cream through week 52. The primary end point was a decrease (improvement) of at least 75% from baseline in the facial Vitiligo Area Scoring Index (F-VASI; range, 0 to 3, with higher scores indicating a greater area of facial depigmentation), or F-VASI75 response, at week 24. There were five key secondary end points, including improved responses on the Vitiligo Noticeability Scale.

RESULTS

A total of 674 patients were enrolled, 330 in TRuE-V1 and 344 in TRuE-V2. In TRuE-V1, the percentage of patients with an F-VASI75 response at week 24 was 29.8% in the ruxolitinib-cream group and 7.4% in the vehicle group (relative risk, 4.0; 95% confidence interval [CI], 1.9 to 8.4; P<0.001). In TRuE-V2, the percentages were 30.9% and 11.4%, respectively (relative risk, 2.7; 95% CI, 1.5 to 4.9; P<0.001). The results for key secondary end points showed superiority of ruxolitinib cream over vehicle control. Among patients who applied ruxolitinib cream throughout 52 weeks, adverse events occurred in 54.8% in TRuE-V1 and 62.3% in TRuE-V2; the most common adverse events were application-site acne (6.3% and 6.6%, respectively), nasopharyngitis (5.4% and 6.1%), and application-site pruritus (5.4% and 5.3%).

CONCLUSIONS

In two phase 3 trials, application of ruxolitinib cream resulted in greater repigmentation of vitiligo lesions than vehicle control through 52 weeks, but it was associated with acne and pruritus at the application site. Larger and longer trials are required to determine the effect and safety of ruxolitinib cream in patients with vitiligo.

Unmet Medical Needs in Chronic, Non-communicable Inflammatory Skin Diseases

An estimated 20-25% of the population is affected by chronic, non-communicable inflammatory skin diseases. Chronic skin inflammation has many causes. Among the most frequent chronic inflammatory skin diseases are atopic dermatitis, psoriasis, urticaria, lichen planus, and hidradenitis suppurativa, driven by a complex interplay of genetics and environmental factors. Autoimmunity is another important cause of chronic skin inflammation. The autoimmune response may be mainly T cell driven, such as in alopecia areata or vitiligo, or B cell driven in chronic spontaneous urticaria, pemphigus and pemphigoid diseases. Rare causes of chronic skin inflammation are autoinflammatory diseases, or rheumatic diseases, such as cutaneous lupus erythematosus or dermatomyositis. Whilst we have seen a significant improvement in diagnosis and treatment, several challenges remain. Especially for rarer causes of chronic skin inflammation, early diagnosis is often missed because of low awareness and lack of diagnostics. Systemic immunosuppression is the treatment of choice for almost all of these diseases. Adverse events due to immunosuppression, insufficient therapeutic responses and relapses remain a challenge. For atopic dermatitis and psoriasis, a broad spectrum of innovative treatments has been developed. However, treatment responses cannot be predicted so far. Hence, development of (bio)markers allowing selection of specific medications for individual patients is needed. Given the encouraging developments during the past years, we envision that many of these challenges in the diagnosis and treatment of chronic inflammatory skin diseases will be thoroughly addressed in the future.

Rapid Improvement in Skin Pain Severity and Its Impact on Quality of Life in Adult Patients With Moderate-to-Severe Atopic Dermatitis From a Double-Blind, Placebo-Controlled Baricitinib Phase 3 Study

BACKGROUND

Skin pain (discomfort/soreness) is a common symptom associated with atopic dermatitis (AD).

OBJECTIVE

To evaluate rapid changes in skin pain severity with baricitinib, and its impact on patient quality of life (QoL) in adults with moderate-to-severe AD who were inadequate responders to topical therapy.

METHODS

Adult patients with moderate-to-severe AD who were inadequate responders to topical therapies (N = 440, BREEZE-AD5 [NCT03435081]) were randomized to once-daily placebo, baricitinib 1 mg, or baricitinib 2 mg for 16 weeks. Change in Skin Pain Numeric Rating Scale (NRS) scores were assessed for the randomized population. Skin Pain NRS and Dermatology Life Quality Index (DLQI) scores were assessed for Skin Pain Response groups and patients with Body Surface Area (BSA) 10% to 50%.

RESULTS

Skin Pain NRS improvement was significant versus placebo by day 1 baricitinib 2 mg (least squares mean [LSM] difference -4.4%, P = .048) and by day 2 for baricitinib 1 mg (-6.7%, P = .011). As measured weekly, improvement was significant starting at Week 1 and remained significant through Week 16 for both doses. At Week 16, 70.9% of Skin Pain NRS responders vs 10.4% of nonresponders had a clinically meaningful improvement in DLQI (P < .0001). At week 16, LSM DLQI change from baseline was -11.1 for all Skin Pain NRS responders versus -3.5 for nonresponders (P < .0001). Patients with BSA 10% to 50% showed similar trends.

CONCLUSIONS

Patients with moderate-to-severe AD, treated with baricitinib, reported rapid improvements in skin pain severity by day 1 for baricitinib 2 mg and day 2 for baricitinib 1 mg and remained effective through 16 weeks of treatment, which positively impacted patient QoL.

Onset of Symptom Relief Reported in Daily Diaries in Patients With Atopic Dermatitis Treated With Baricitinib in a United States Clinical Trial (BREEZE-AD5)

BACKGROUND

Itch and sleep disturbance due to itch are burdensome symptoms associated with atopic dermatitis (AD). Rapid onset of action is important for AD treatments to improve quality of life and relieve suffering.

OBJECTIVES

This subanalysis evaluated how quickly baricitinib 1-mg and 2-mg reduced itch and associated sleep disturbance during the first 7 days after treatment initiation in a phase 3, double-blind, placebo-controlled trial.

METHODS

Adult patients with AD were randomized 1:1:1 to placebo (N = 147), baricitinib 1 mg (N = 147) or baricitinib 2 mg (N = 146). Patients kept daily diaries, completing the Itch Numeric Rating Scale (NRS) (itch severity from 0 = no itch to 10 = worst itch imaginable) and the Atopic Dermatitis Sleep Scale (ADSS) to measure sleep disturbance (number of nighttime awakenings because of itch). Mixed model repeated measures analysis was used to analyze change from day 1 to day 7 values.

RESULTS

Patients receiving either dose of baricitinib had a 9.9% decrease in itch NRS scores from baseline to Day 2 vs 1.5% decrease for placebo (significant between-group least squares mean [LSM] difference: 8.3; 95% CI -12.66 to -3.89; P = .0002). Baricitinib 2 mg reduced nighttime awakenings due to itch (ADSS item 2) at day 2 by 25.2% vs 3.9% in the placebo group (between-group LSM difference: -21.4, P = .0025). Baricitinib 2 mg continued to demonstrate a statistically significant difference from placebo in sleep symptoms at day 7 (LSM difference -23.9; P = .001).

CONCLUSIONS

Baricitinib 2-mg provided relief from itching and sleep disturbance in patients with AD, beginning the day after taking first dose.Clinical trials at www.clinicaltrials.gov: BREEZE-AD5 (NCT03435081).

Upadacitinib plus topical corticosteroids in atopic dermatitis: week-52 AD Up study results

BACKGROUND

Primary (week 16) results from the ongoing phase 3, double-blind AD Up study (NCT03568318) demonstrate a positive benefit-risk profile for upadacitinib+TCS in patients with moderate-to-severe AD.

OBJECTIVE

Evaluate efficacy and safety of UPA+TCS through 52 weeks.

METHODS

Patients (12-75y) with chronic AD (≥10% of body surface area affected, EASI ≥16, vIGA-AD™ ≥3, and WP-NRS score ≥4) were randomized 1:1:1 to once-daily upadacitinib 15mg+TCS, upadacitinib 30mg+TCS, or PBO+TCS (re-randomized at week 16 to upadacitinib+TCS). Safety and efficacy, including proportion of patients achieving ≥75% improvement in EASI (EASI-75), vIGA-AD of clear/almost clear with improvement ≥2 grades (vIGA-AD 0/1), and WP-NRS improvement ≥4, were assessed through week 52. Missing data were primarily handled by nonresponder imputation incorporating multiple imputation for missing values due to COVID-19.

RESULTS

Of 901 patients, 300 were randomized to upadacitinib 15mg+TCS, 297 to upadacitinib 30mg+TCS, and 304 to PBO+TCS. For all endpoints, efficacy for upadacitinib 15mg+TCS and upadacitinib 30mg+TCS at week 16 was maintained through week 52. At week 52, the proportions of patients treated with upadacitinib 15mg+TCS and upadacitinib 30mg+TCS who achieved EASI-75 were 50.8% and 69.0%, respectively; 33.5% and 45.2%, respectively, achieved vIGA-AD 0/1; and 45.3% and 57.5%, respectively, achieved WP-NRS improvement ≥4. upadacitinib+TCS was well tolerated through 52 weeks; no new important safety risks beyond the current label were observed. No deaths were reported; events of MACE and VTE were infrequent (≤0.2/100 PY).

CONCLUSION

Results through 52 weeks demonstrate long-term maintenance of efficacy and a favorable safety profile of upadacitinib+TCS in patients with moderate-to-severe AD.

Significant improvement of dermatitis herpetiformis with tofacitinib

Dermatitis herpetiformis (DH) is a rare autoimmune blistering disorder in which patients with celiac disease, a gluten-sensitive enteropathy, present with a severely pruritic papulovesicular eruption over extensor surfaces such as the knees, elbows, lower back, buttocks, and neck. Patients are instructed to adhere to a gluten-free diet for purposes of improving their skin disease and gluten-sensitive enteropathy; this is the only treatment that lowers risk of enteropathy-associated T cell lymphoma. Patients who adhere to a strict gluten-free diet often have remission of their skin disease over months to years. Dapsone is a rapid and extremely effective first-line treatment option and often used while transitioning to a gluten-free diet. Aside from gluten-free diet and dapsone, second-line treatment options include sulfapyridine, sulfasalazine, and colchicine. Some patients have difficulty adhering to a gluten-free diet or develop intolerable side effects to systemic therapies. Furthermore, there is limited data on the use of the second-line treatments. Recent studies have shed light on the role of JAK-STAT-dependent pathways in the pathogenesis of dermatitis herpetiformis. We present a patient treated with tofacitinib, 5mg twice daily, an oral JAK1/3 inhibitor, who demonstrated clinical improvement of DH and control of new lesion development.
