Clinical Benefits of Baricitinib Therapy According to Scalp Hair Regrowth in Patients with Severe Alopecia Areata.

OBJECTIVES: The present analyses report integrated results from BRAVE-AA1 (NCT03570749) and BRAVE-AA2 (NCT03899259) on the clinical benefits of baricitinib treatment on the basis of the amount of scalp hair regrowth through 52 weeks of treatment. METHODS: This post hoc analysis was conducted with data from patients who were treated continuously for 52 weeks with baricitinib 4 mg or 2 mg. Clinical outcomes were assessed using the Severity of Alopecia Tool (SALT) and Clinician-Reported Outcome (ClinRO) for Eyebrow (EB) and Eyelash (EL) hair. Secondary measures included the Hospital Anxiety and Depression Scale and Skindex-16 adapted for alopecia areata. At week 52, patients were classified into three subgroups: SALT ≤ 20 response, intermediate response (achieved a 30% improvement from baseline (SALT30) without a SALT score ≤ 20), or nonresponse (never achieved SALT30). The criterion of SALT30 approximates a minimal clinical meaningful response to therapy. RESULTS: At week 52, with baricitinib 4 mg treatment, the greatest (70%) improvement in EB and EL was observed in responders, but approximately 50% of patients with intermediate response and 20% of nonresponders experienced complete/nearly complete EB and EL regrowth. Improvement in emotional distress was directionally related to improvements in scalp hair regrowth, while impact on quality of life was proportionately greater for the responder subgroup. CONCLUSIONS: Clinically meaningful regrowth in eyebrow and eyelash hair can occur in the absence of complete scalp hair regrowth after treatment with baricitinib. Emotional distress and quality of life improvement is most associated with obtaining a clinical meaningful improvement in scalp hair.

Efficacy of Baricitinib in Patients with Various Degrees of Alopecia Areata Severity: Post-Hoc Analysis from BRAVE AA1 and BRAVE AA2.

BACKGROUND: Baricitinib, an oral selective JAK1/JAK2 inhibitor, is approved for the treatment of adults with severe alopecia areata (AA). OBJECTIVE: To evaluate differences in response up to week 52 among subgroups based on the baseline severity of AA assessed with the Severity of Alopecia Tool (SALT) score. METHODS: Data were pooled from BRAVE-AA1 and BRAVE-AA2, two randomized, placebo-controlled, phase 3 trials, which enrolled adults with a SALT score ≥ 50. Patients were subdivided by the degree of AA severity at baseline. RESULTS: Among the 855 patients treated with baricitinib 2 mg and 4 mg, improvements in scalp hair growth continued through to week 52. A superior response was observed in patients with a SALT score of 50-94 versus a score of 95-100. Patients on baricitinib 4 mg had a faster and higher response rate compared to baricitinib 2 mg. CONCLUSION: Across all degrees of severity for baricitinib 2 mg and 4 mg doses, the proportion of patients responding was yet to plateau up to week 52. Response to treatment was longer for patients with a baseline SALT score 95-100. Further studies are needed to analyze other parameters that may impact observed response rates.

When to expect scalp hair regrowth during treatment of severe alopecia areata with baricitinib: insights from trajectories analyses of patients enrolled in two phase III trials.

BACKGROUND: Baricitinib is approved for the treatment of adults with severe alopecia areata (AA). In the absence of robust data on the patterns of regrowth during treatment of severe AA, there is a gap in the knowledge regarding treatment expectations. OBJECTIVES: To examine whether different clinical response subgroups could be identified in baricitinib-treated patients with severe AA and factors that contribute to these subgroups. METHODS: The BRAVE-AA1 and BRAVE-AA2 phase III trials enrolled patients with severe AA [Severity of Alopecia Tool (SALT) score ≥ 50 (≥ 50% scalp hair loss)]. Patients randomized to baricitinib 4 mg or 2 mg retained their treatment allocation for 52 weeks. Based on patterns identified through growth mixture modelling (GMM), patients were categorized into responder subgroups according to when they first achieved ≥ 30% improvement from baseline in SALT score (SALT30). For each responder subgroup, trajectories of response (i.e. achievement of a SALT score ≤ 20, SALT score ≤ 10 and ≥ 50% change from baseline in SALT score) and baseline disease characteristics are reported. RESULTS: Respectively, 515 and 340 patients were randomized to once-daily baricitinib 4 mg and 2 mg at baseline; 69% and 51%, respectively, achieved SALT30 at least once by week 52. Based on GMM findings, we identified three responder subgroups: early (SALT30 by week 12), gradual (SALT30 after week 12-week 36) and late (SALT30 after week 36-week 52). The proportions of early, gradual and late responders and nonresponders were, respectively, 33%, 28%, 8% and 31% among patients treated with baricitinib 4 mg, and 20%, 23%, 9% and 49%, respectively, among those treated with baricitinib 2 mg. Early responders had a shorter trajectory to maximal clinical outcomes (e.g. > 78% achieved a SALT score ≤ 20 by week 36) vs. gradual or late responders. Early responders were more frequent among patients with baseline severe AA (SALT score 50 to < 95) vs. very severe AA (SALT score 95-100). Overall, responders (early to late) were more frequent in patients with short (< 4 years) episodes of hair loss. CONCLUSIONS: These analyses identified early, gradual and late responder subgroups for scalp hair regrowth in baricitinib-treated patients with severe AA, and that these subgroups are influenced by baseline characteristics. Findings from these analyses will help to inform treatment expectations for scalp hair regrowth.

Clinical Outcomes for Uptitration of Baricitinib Therapy in Patients With Severe Alopecia Areata: A Pooled Analysis of the BRAVE-AA1 and BRAVE-AA2 Trials.

Importance: Baricitinib is an oral selective Janus kinase 1/2 inhibitor that has achieved clinically meaningful outcomes for scalp, eyebrow, and eyelash hair regrowth in patients with severe alopecia areata (AA) at week 36 of treatment. Treatment with baricitinib, 4 mg, has resulted in higher response rates than baricitinib, 2 mg, at weeks 36 and 52. Objective: To determine the efficacy of uptitration to baricitinib, 4 mg, for 24 weeks in patients who had previously not responded to baricitinib, 2 mg (Severity of Alopecia Tool [SALT] score of >20). Design, Setting, and Participants: BRAVE-AA1 and BRAVE-AA2 are multicenter, placebo-controlled, phase 3 randomized clinical trials that were initiated on September 24, 2018, and July 8, 2019, respectively, with follow-up to 200 weeks (data cutoffs of November 11, 2021, and November 5, 2021, respectively). This pooled analysis reports long-term extension data up to week 76. At baseline, 1200 adult patients with severe AA (SALT score ≥50) were randomly assigned in a 3:2:2 ratio to receive baricitinib, 4 mg; baricitinib, 2 mg; or placebo. Patients treated with baricitinib remained on the same treatment dose until week 52. Patients were considered nonresponders to baricitinib, 2 mg, if they had a SALT score greater than 20 after 52 weeks of therapy. Main Outcomes and Measures: The proportions of patients achieving a SALT score of 20 or lower and clinician-reported outcome for eyebrow hair loss and eyelash hair loss scores of 0 or 1 (full coverage or minimal gaps) with 2-point or higher improvements from baseline (among those with baseline scores ≥2 [significant gaps to no notable hair]) were analyzed through week 76. Results: At week 52, of the 340 patients (mean [SD] age, 38.4 [12.9] years; 212 [62.4%] female) treated with baricitinib, 2 mg, 212 (62.4%) had a SALT score higher than 20 and were uptitrated to baricitinib, 4 mg. Two-thirds of these patients (142 of 212 [67.0%]) had a baseline SALT score of 95 to 100, indicating very severe AA. At week 76, 55 of the 212 patients (25.9%) had achieved a SALT score of 20 or lower. During the same period, response rates for clinician-reported outcome scores of 0 or 1 increased from 19.3% (31 of 161 patients) to 37.9% (61 of 161 patients) for eyebrows and from 24.1% (33 of 137 patients) to 40.9% (56 of 137 patients) for eyelashes. Conclusions and Relevance: In this pooled analysis of the BRAVE-AA1 and BRAVE-AA2 trials, uptitration of baricitinib, 2 mg, to baricitinib, 4 mg, in those who did not respond to the 2-mg dose resulted in meaningful improvement of response rates over the subsequent 24 weeks for scalp, eyebrow, and eyelash hair loss.

Scalp hair regrowth is associated with improvements in health-related quality of life and psychological symptoms in patients with severe alopecia areata: results from two randomized controlled trials.

INTRODUCTION: This post hoc analysis assessed association between scalp hair regrowth and improvements in health-related quality of life (HRQoL) and psychological burden in patients with severe alopecia areata (AA). METHODS: Data were pooled from two phase-3 trials (N = 1200). Patients randomized to once-daily placebo, baricitinib 2-mg, or 4-mg were analyzed independently of treatment allocation, and categorized according to scalp hair regrowth (at Week 36): meaningful regrowth (Severity of Alopecia Tool (SALT) score ≤20); intermediate regrowth (≥30% SALT improvement [SALT30] at any post-baseline visit to Week 36, but SALT score > 20 at Week 36); no/minimal regrowth (never achieved SALT30). Skindex-16 for AA score change-from-baseline and proportion of patients with baseline Hospital Anxiety and Depression Scale (HADS) scores ≥8 that shifted to <8 (normal) were assessed. RESULTS: Patients with meaningful regrowth achieved greater improvements in all Skindex-16 AA domains versus no/minimal regrowth. More patients with meaningful versus no/minimal regrowth shifted from HADS ≥8 to <8 (anxiety:46.8% versus 26.4%; depression:52.3% versus 24.0%). Improvements occurred with intermediate regrowth but to a lesser extent versus meaningful regrowth. CONCLUSIONS: Patients with severe AA and scalp hair regrowth at Week 36 experienced greater improvements in HRQoL and anxiety and depression versus patients with no/minimal regrowth. The highest benefit was observed in patients with meaningful regrowth (SALT score ≤20).ClinicalTrials.gov listing: NCT03570749 and NCT03899259.

Efficacy and Safety of Baricitinib in Patients with Severe Alopecia Areata over 52 Weeks of Continuous Therapy in Two Phase III Trials (BRAVE-AA1 and BRAVE-AA2).

BACKGROUND: The oral Janus kinase (JAK) inhibitor baricitinib has demonstrated efficacy for severe alopecia areata (AA) over 36 weeks. There are limited data on the longer-term treatment of AA. OBJECTIVE: The aim of this study was to evaluate the efficacy and safety of baricitinib for AA in adults with ≥50% scalp hair loss through 52 weeks of continuous therapy in two phase III trials (BRAVE-AA1 and BRAVE-AA2). METHODS: Patients randomized to baricitinib at baseline in BRAVE-AA1 (N = 465) and BRAVE-AA2 (N = 390) retained their treatment allocation through Week 52. Efficacy outcomes included the proportion of patients achieving a Severity of Alopecia Tool (SALT) score ≤ 20 (≤ 20% scalp hair loss). Data were censored after permanent treatment discontinuation or if collected remotely due to the coronavirus disease 2019 (COVID-19) pandemic. RESULTS: Response rates for hair regrowth increased over the 52-week period. Of patients treated with baricitinib 4 mg and 2 mg, respectively, 40.9% and 21.2% in BRAVE-AA1 and 36.8% and 24.4% in BRAVE-AA2 achieved a SALT score ≤ 20 at Week 52. The most frequent treatment-emergent adverse events included upper respiratory tract infection, headache, nasopharyngitis, acne, urinary tract infection, creatine phosphokinase elevation, and COVID-19 infection. LIMITATION: There were no comparisons with placebo. CONCLUSION: Efficacy of baricitinib for adults with severe AA continuously improved over 52 weeks, indicating that long-term treatment may be necessary to observe maximum clinical benefit. There were no new safety signals. CLINICALTRIALS REGISTRATION: ClinicalTrials.gov NCT03570749 and NCT03899259. Efficacy and Safety of Baricitinib in Patients with Severe Alopecia Areata: Week-52 Results from BRAVE-AA1 and BRAVE-AA2.

Alopecia areata (AA) is an autoimmune disease that causes patchy hair loss on the scalp, face, and body. Baricitinib is a Janus kinase inhibitor that is approved to treat AA in several countries, based on results from two studies, BRAVE-AA1 and BRAVE-AA2. In these studies, adults with at least 50% scalp hair loss were treated with baricitinib for 36 weeks. Long-term therapy is important in AA, and hair regrowth can take longer in some patients with severe disease. Therefore, we assessed outcomes from a longer course of therapy. In this study, we report the results after 52 weeks of continuous treatment with baricitinib 4 mg or 2 mg in 465 patients in BRAVE-AA1 and 390 patients BRAVE-AA2. The goal was to reduce scalp hair loss to 20% or less by Week 52. In BRAVE-AA1, 40.9% of patients who took baricitinib 4 mg and 21.2% of patients who took baricitinib 2 mg had 20% or less missing scalp hair by Week 52. Similarly, in BRAVE-AA2, 36.8% of patients who took baricitinib 4 mg and 24.4% of patients who took baricitinib 2 mg had 20% or less missing scalp hair by Week 52. The most common adverse effects that were reported during the study period were upper respiratory tract infection, headache, nasopharyngitis, acne, urinary tract infection, creatine phosphokinase elevation, and coronavirus disease 2019 (COVID-19) infection. The results of longer-term treatment indicate that hair regrowth continues to improve without any new safety concerns for adults with severe AA taking baricitinib.

Integrated safety analysis of baricitinib in adults with severe alopecia areata from two randomized clinical trials.

BACKGROUND: Baricitinib, an oral, selective, reversible Janus kinase (JAK)1/JAK2 inhibitor, is an approved treatment for adults with severe alopecia areata (AA) in the USA, European Union and Japan. OBJECTIVES: To report safety data for baricitinib in patients with severe AA from two clinical trials including long-term extension periods. METHODS: This analysis includes pooled patient-level safety data from two trials, an adaptive phase II/III trial (BRAVE-AA1) and a phase III trial (BRAVE-AA2) (ClinicalTrials.gov, NCT03570749 and NCT03899259). Data are reported in three datasets: (i) the placebo-controlled dataset (up to week 36): baricitinib 2 mg and 4 mg vs. placebo; (ii) the extended dataset (up to the data cutoff): patients remaining on continuous treatment with baricitinib 2 mg or 4 mg from baseline; and (iii) the all-baricitinib dataset (all-BARI, up to the data cutoff): all patients receiving any dose of baricitinib at any time during the trials. Safety outcomes include treatment-emergent adverse events (TEAEs), adverse events of special interest and abnormal laboratory changes. Proportions of patients with events and incidence rates (IR) were calculated. RESULTS: Data were collected for 1303 patients who were given baricitinib, reflecting 1868 patient-years of exposure (median 532 days). The most frequently reported TEAEs during the placebo-controlled period (based on the baricitinib 4-mg group) were upper respiratory tract infection, nasopharyngitis, headache, acne and elevated blood creatine phosphokinase (CPK). During the placebo-controlled period, the frequency of acne was higher with baricitinib than placebo, and elevated CPK was higher with baricitinib 4 mg than placebo and baricitinib 2 mg. In all-BARI, the IR of serious infections was low (n = 16, IR 0.8). There was one opportunistic infection (IR 0.1), and 34 cases of herpes zoster (IR 1.8). There was one positively adjudicated major adverse cardiovascular event (myocardial infarction) (IR 0.1), one pulmonary embolism (IR 0.1), three malignancies other than nonmelanoma skin cancer (IR 0.2) and one gastrointestinal perforation (IR 0.1). No deaths were reported. CONCLUSIONS: This integrated safety analysis in patients with severe AA is consistent with the overall safety profile of baricitinib. Some differences with atopic dermatitis were noted that may be attributable to the disease characteristics of AA.

Efficacy and safety of baricitinib in combination with topical corticosteroids in patients with moderate-to-severe atopic dermatitis with inadequate response, intolerance or contraindication to ciclosporin: results from a randomized, placebo-controlled, phase III clinical trial (BREEZE-AD4).

BACKGROUND: Baricitinib, an oral selective Janus kinase (JAK)1 and JAK 2 inhibitor, was shown to improve the signs and symptoms of moderate-to-severe atopic dermatitis (AD). OBJECTIVES: To evaluate the efficacy and safety of baricitinib with background topical corticosteroids (TCS) in patients with moderate-to-severe AD and inadequate response, intolerance or contraindication to ciclosporin A (CA). METHODS: In this double-blind, randomized, placebo-controlled, phase III study, patients were randomized 1: 1: 2: 1 to placebo (N = 93), baricitinib 1 mg (N = 93), 2 mg (N = 185) or 4 mg (N = 92) with background TCS. The primary endpoint was the proportion of patients receiving baricitinib 4 mg or 2 mg (+ TCS) vs. placebo + TCS who achieved ≥ 75% improvement from baseline in the Eczema Area and Severity Index (EASI 75) at week 16. RESULTS: Baricitinib 4 mg + TCS was superior to placebo + TCS for EASI 75 (4 mg: 32%, placebo: 17%, P = 0·031) at week 16 and for improvements in itch, skin pain and number of night-time awakenings owing to itch. Improvements were maintained through 52 weeks of treatment. Treatment-emergent adverse events (TEAEs) were more common with baricitinib than placebo (+ TCS); most were mild or moderate. The most frequent TEAEs with baricitinib 4 mg + TCS were nasopharyngitis, herpes simplex, influenza and headache. No deaths or deep vein thromboses were reported. CONCLUSIONS: Baricitinib 4 mg + TCS improved the signs and symptoms of moderate-to-severe AD through 52 weeks of treatment in patients with inadequate response, intolerance or contraindication to CA. The safety profile was consistent with previous studies of baricitinib in moderate-to-severe AD. What is already known about this topic? Ciclosporin A is indicated for the treatment of atopic dermatitis that is refractory to topical therapies. However, its use is limited by safety concerns and it may not provide adequate response for some patients. Baricitinib, an oral selective Janus kinase (JAK)1 and JAK2 inhibitor, has been shown to improve the signs and symptoms of moderate-to-severe atopic dermatitis as a monotherapy or in combination with topical corticosteroids. What does this study add? Baricitinib combined with background low- or moderate-potency topical corticosteroids provided improvements in the signs and symptoms of moderate-to-severe atopic dermatitis through 1 year of treatment in patients with a contraindication, intolerance or failure to respond to ciclosporin A. The most common treatment-emergent adverse events with baricitinib 4 mg were nasopharyngitis, herpes simplex, influenza and headache. The safety profile was consistent with previous studies in patients with moderate-to-severe atopic dermatitis.

Two Phase 3 Trials of Baricitinib for Alopecia Areata.

BACKGROUND: Alopecia areata is an autoimmune condition characterized by rapid hair loss in the scalp, eyebrows, and eyelashes, for which treatments are limited. Baricitinib, an oral, selective, reversible inhibitor of Janus kinases 1 and 2, may interrupt cytokine signaling implicated in the pathogenesis of alopecia areata. METHODS: We conducted two randomized, placebo-controlled, phase 3 trials (BRAVE-AA1 and BRAVE-AA2) involving adults with severe alopecia areata with a Severity of Alopecia Tool (SALT) score of 50 or higher (range, 0 [no scalp hair loss] to 100 [complete scalp hair loss]). Patients were randomly assigned in a 3:2:2 ratio to receive once-daily baricitinib at a dose of 4 mg, baricitinib at a dose of 2 mg, or placebo. The primary outcome was a SALT score of 20 or less at week 36. RESULTS: We enrolled 654 patients in the BRAVE-AA1 trial and 546 in the BRAVE-AA2 trial. The estimated percentage of patients with a SALT score of 20 or less at week 36 was 38.8% with 4-mg baricitinib, 22.8% with 2-mg baricitinib, and 6.2% with placebo in BRAVE-AA1 and 35.9%, 19.4%, and 3.3%, respectively, in BRAVE-AA2. In BRAVE-AA1, the difference between 4-mg baricitinib and placebo was 32.6 percentage points (95% confidence interval [CI], 25.6 to 39.5), and the difference between 2-mg baricitinib and placebo was 16.6 percentage points (95% CI, 9.5 to 23.8) (P<0.001 for each dose vs. placebo). In BRAVE-AA2, the corresponding values were 32.6 percentage points (95% CI, 25.6 to 39.6) and 16.1 percentage points (95% CI, 9.1 to 23.2) (P<0.001 for each dose vs. placebo). Secondary outcomes for baricitinib at a dose of 4 mg but not at a dose of 2 mg generally favored baricitinib over placebo. Acne, elevated levels of creatine kinase, and increased levels of low- and high-density lipoprotein cholesterol were more common with baricitinib than with placebo. CONCLUSIONS: In two phase 3 trials involving patients with severe alopecia areata, oral baricitinib was superior to placebo with respect to hair regrowth at 36 weeks. Longer trials are required to assess the efficacy and safety of baricitinib for alopecia areata.

Efficacy and safety of the oral Janus kinase inhibitor baricitinib in the treatment of adults with alopecia areata: Phase 2 results from a randomized controlled study.

BACKGROUND: There are no treatments approved by the Food and Drug Administration for alopecia areata. OBJECTIVE: To evaluate the efficacy and safety of baricitinib in patients with ≥50% scalp hair loss in a phase 2 study of adults with alopecia areata (BRAVE-AA1). METHODS: Patients were randomized 1:1:1:1 to receive placebo or baricitinib 1 mg, 2 mg, or 4 mg once daily. Two consecutive interim analyses were performed after all patients completed weeks 12 and 36 or had discontinued treatment prior to these time points. The primary endpoint was the proportion of patients achieving a Severity of Alopecia Tool (SALT) score ≤20 at week 36. Logistic regression was used with nonresponder imputation for missing data. RESULTS: A total of 110 patients were randomized (placebo, 28; baricitinib 1-mg, 28; 2-mg, 27; 4-mg, 27). The baricitinib 1-mg dose was dropped after the first interim analysis based on lower SALT30 response rate. At week 36, the proportion of patients achieving a SALT score of ≤20 was significantly greater in baricitinib 2-mg (33.3%, P = .016) and 4-mg (51.9%, P = .001) groups versus placebo (3.6%). Baricitinib was well tolerated with no new safety findings. LIMITATIONS: Small sample size limits generalizability of results. CONCLUSION: These results support the efficacy and safety of baricitinib in patients with ≥50% scalp hair loss.

An Analysis of Patient-reported Outcomes in IXORA-S: Comparing Ixekizumab and Ustekinumab over 52 Weeks in Moderate-to-severe Psoriasis.

Patient-reported outcomes are valuable for assessing new psoriasis therapies. This study investigated patient-reported outcomes in patients with moderate-to-severe plaque psoriasis treated with ixekizumab or ustekinumab, dosed according to their respective labels, for 52 weeks (IXORA-S-NCT02561806). Patient-reported outcomes investigated included patient global assessment, pruritus, skin pain, health-related quality of life, and work productivity. Ixekizumab-treated patients reported greater improvements in patient-reported outcomes sooner after treatment compared with ustekinumab-treated patients, and maintained greater improvements in patient global assessment scores (ixekizumab 0.72, ustekinumab 1.19; p < 0.001), rates of Dermatology Life Quality Index (0, 1) (ixekizumab 71.3%, ustekinumab 56.6%, p < 0.01), and 36-item Short-form Health survey physical component summary score change from baseline (ixekizumab 5.53, ustekinumab 3.28; p < 0.05) at week 52. While clinically meaningful improvements in patient-reported outcomes resulted with either treatment, ixekizumab provided more rapid improvements in patient-reported outcomes and superior outcomes for some assessments through one year of treatment, while maintaining statistically superior improvements in skin severity, as assessed by either physicians or patients.

The Role of Patients in Alopecia Areata Endpoint Development: Understanding Physical Signs and Symptoms.

Meaningful patient input to understand disease experience and patient expectations for improvement with treatment is essential for the selection and development of outcome measures for alopecia areata (AA) clinical trials. This study explored the physical signs and symptoms of AA through 30 semistructured interviews with adult (n = 25) and adolescent (n = 5) patients experienced with severe or very severe AA. Scalp hair loss was overwhelmingly the most important sign and symptom of AA. Nearly all patients (90%) considered scalp hair loss in their top three most bothersome physical signs and symptoms of AA, with 77% (n = 23) naming scalp hair loss as the most bothersome symptom. Other identified signs and symptoms in the top three most bothersome included eyebrow, eyelash, nose, body, and facial hair loss, as well as eye irritation and nail damage and/or appearance. Eyebrow (16%, n = 4), eyelash (4%, n = 1), nasal (4%, n = 1), and body (4%, n = 1) hair loss were identified by seven adult patients as the most bothersome signs and symptoms of AA. Conceptual saturation confirmed that a comprehensive understanding of this patient population's physical AA-related signs and symptoms was obtained. These findings indicate that the primary objective for new AA treatments for this patient population should be meaningful improvement in scalp hair growth to address the most troubling unmet need.

"'You lose your hair, what's the big deal?' I was so embarrassed, I was so self-conscious, I was so depressed:" a qualitative interview study to understand the psychosocial burden of alopecia areata.

BACKGROUND: Alopecia areata (AA) is characterized by hair loss that can affect the scalp and body. This study describes the psychosocial burden of AA. METHODS: Participants diagnosed with AA who had experienced ≥50% scalp hair loss according to the Severity of Alopecia Tool (SALT) were identified by clinicians. A semi-structured interview guide, developed with expert clinician input, included open-ended questions to explore patients' experiences of living with AA. Data were thematically analyzed to identify concepts and relationships. RESULTS: Participants (n = 45, 58% female, mean age 33.3 years [range 15-72], mean SALT 67.2 [range 0-100]) described the AA diagnosis as "devastating". Both males and females reported emotional and psychological impacts of AA including feeling sad/depressed (n = 21), embarrassed/ashamed (n = 10) and angry/frustrated (n = 3). Patients felt helpless (n = 5) due to the unpredictability of disease recurrence, and anxious (n = 19) about judgement from others. Many patients avoided social situations (n = 18), which impaired relationships and increased isolation. Coping strategies included concealment of hair loss through wigs or make-up, although fear of the displacement of these coverings also caused anxiety and the avoidance of activities that could result in scalp exposure (n = 22). Some patients became more accepting of AA over time, which lessened the emotional impact, though efficacious treatment was still desired. A conceptual framework was developed, and a conceptual model was created to depict the relationship between the physical signs/symptoms and the associated psychosocial effects of AA. CONCLUSION: AA impairs patients' emotional and psychological wellbeing, relationships and lifestyles. Greater disease awareness and effective treatments are needed.

Development of Clinician-Reported Outcome (ClinRO) and Patient-Reported Outcome (PRO) Measures for Eyebrow, Eyelash and Nail Assessment in Alopecia Areata.

BACKGROUND: Eyebrow and eyelash hair loss and nail damage-in addition to scalp hair loss-are important signs/symptoms of alopecia areata (AA) to patients and deserve assessment in AA clinical trials. OBJECTIVES: Our objective was to develop clinician-reported outcome (ClinRO) and patient-reported outcome (PRO) measures and accompanying photoguides to aid in the assessment of AA-related eyebrow, eyelash and nail signs/symptoms. METHODS: Iterative rounds of qualitative, semi-structured interviews were conducted with US expert dermatologists and North American patients with AA. Patients with eyebrow, eyelash and nail involvement were purposefully sampled. Interview transcripts were qualitatively analyzed. RESULTS: Dermatologists (n = 10) described eyebrow and eyelash loss as concerning for affected patients and, along with nail appearance, as deserving assessment. Dermatologist data informed the development of single item, 4-point Likert-type ClinRO and PRO measures of current eyebrow loss, eyelash loss and nail appearance and a PRO measure of eye irritation. Patients (n = 45, age 15-72 years) confirmed the importance and relevance of these signs/symptoms. Interim revision resulted in measures that were understood by and relevant to patients. Dermatologists (n = 5) and patients (n = 10, age 21-54 years) participated in the development of the eyebrow, eyelash and nail photoguides and confirmed that they included photos that appropriately represented different severity levels and were helpful to derive and standardize ratings across raters. CONCLUSIONS: The ClinRO and PRO measures for eyebrow, eyelash and nail appearance, with their accompanying photoguides and the PRO Measure for Eye Irritation provide clear and meaningful assessments of outcomes important to patients with AA.

Ixekizumab and Ustekinumab Efficacy in Nail Psoriasis in Patients with Moderate-to-Severe Psoriasis: 52-Week Results from a Phase 3, Head-to-Head Study (IXORA-S).

INTRODUCTION: Patients with plaque psoriasis often have nail psoriasis, which is difficult to treat. Ixekizumab (IXE) and ustekinumab (UST) are biologics with established efficacy in nail psoriasis. We present post hoc data from a head-to-head trial of IXE and UST (IXORA-S) to examine the efficacy in nail psoriasis in patients with moderate-to-severe plaque psoriasis over 52 weeks. METHODS: In IXORA-S, randomised patients received IXE (N = 136) or UST (N = 166) per label for 52 weeks. Eighty-four (61.8%) and 105 (63.3%) of the patients treated with IXE or UST, respectively, had baseline fingernail psoriasis (Nail Psoriasis Severity Index [NAPSI] > 0); of these, 54 (64.3%) and 63 (60.0%) patients, respectively, had significant baseline fingernail psoriasis (defined as NAPSI ≥ 16 with ≥ 4 fingernails involved). The proportion of patients achieving NAPSI = 0, a NAPSI score change from baseline and correlations in Psoriasis Area of Severity Index (PASI) and NAPSI improvement over 52 weeks were examined. RESULTS: Progressive improvement occurred in both treatment groups over 52 weeks. Statistically significantly more patients achieved NAPSI = 0 with IXE versus UST by week 16-20, and the proportions continued to increase through week 52 among patients with baseline nail psoriasis (61.9 vs. 28.6%, respectively; P < 0.001), including those with significant nail psoriasis (57.4 vs. 17.5%, respectively; P < 0.001). Similar results were observed for NAPSI score improvement from baseline to week 52. Interestingly, the presence of nail psoriasis was associated with lower skin response with UST but not with IXE. CONCLUSIONS: Ixekizumab was superior to UST in the clearance of nail psoriasis, with earlier improvement continued through 52 weeks regardless of baseline nail severity.

The Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD): The development and reliability testing of a novel clinical outcome measurement instrument for the severity of atopic dermatitis.

BACKGROUND: An Investigator Global Assessment (IGA) is recommended by health agencies for drug registration in atopic dermatitis (AD). Current IGA scales lack standardization. OBJECTIVES: To develop an IGA scale, training module, and clinical certification examination for use in AD trials; establish content validity; and assess reliability. METHODS: Expert dermatologists participated in the development of the validated IGA for AD (vIGA-ADTM). Reliability (interrater and intrarater) was assessed by 2 web-based surveys. Clinical certification for investigators consisted of a training module and examination. RESULTS: Expert consensus was achieved around a 5-point IGA scale including morphologic descriptions, and content validity was established. Survey 1 showed strong interrater reliability (Kendall's coefficient of concordance W [Kendall's W], 0.809; intraclass correlation [ICC], 0.817) and excellent agreement (weighted kappa, 0.857). Survey 2, completed 5 months after training of dermatologists, showed improvements in scale reliability (Kendall's W, 0.819; ICC, 0.852; weighted kappa, 0.889). In this study, 627 investigators completed vIGA-AD training and certification. LIMITATIONS: Ratings were assessed on photographs. CONCLUSION: A validated IGA scale and training module were developed with the intent of harmonizing assessment of disease severity in AD trials. Strong reliability and excellent agreement between assessments were observed.

Efficacy and safety of ixekizumab in patients with plaque psoriasis across different degrees of disease severity: results from UNCOVER-2 and UNCOVER-3.

PURPOSE: To evaluate short- and long-term efficacy and safety of ixekizumab in patients according to psoriasis severity. MATERIALS AND METHODS: Data were integrated from clinical trials (UNCOVER-2, UNCOVER-3). Patients received placebo, 80-mg ixekizumab every 2 weeks (IXEQ2W), every 4 weeks (IXEQ4W), or 50 mg etanercept (ETN) biweekly for 12 weeks, then open-label IXEQ4W (UNCOVER-3). Psoriasis severity was categorized by baseline Psoriasis Area and Severity Index (PASI <20 and ≥20). Efficacy was evaluated by percentage reaching PASI 75, 90, 100, and absolute PASI ≤5, ≤2, and ≤1. RESULTS: Significantly more patients with PASI ≥20 (vs. PASI <20) were male and had higher body weight. After 12 weeks, both severity groups had significantly more IXEQ2W- than ETN-treated patients reach PASI 75, 90, 100, and absolute PASI ≤5, ≤2, ≤1. Fewer PASI ≥20 vs. PASI <20 patients across treatments reached PASI ≤5, ≤2, and ≤1 at week 12. Efficacy was maintained during 156 weeks of ixekizumab treatment with no differences between groups. The IXEQ2W safety profile was similar between groups except for injection-site reactions (significantly higher in PASI <20). CONCLUSIONS: Ixekizumab demonstrated a high level of efficacy and had a consistent safety profile in patients with different baseline psoriasis severity levels.

Ixekizumab provides superior efficacy compared with ustekinumab over 52 weeks of treatment: Results from IXORA-S, a phase 3 study.

BACKGROUND: Biologics targeting interleukin 17A (IL-17A) allow for rapid clearance of psoriatic plaques, with a clinically favorable safety profile. OBJECTIVES: To compare the safety and efficacy of ixekizumab, an IL-17A antagonist, with the safety and efficacy of the IL-12/23 inhibitor ustekinumab through 52 weeks of treatment in the head-to-head trial IXORA-S. METHODS: Patients were randomized to ixekizumab (n = 136) or ustekinumab (n = 166) and dosed per the approved labels. After 1 year, efficacy was assessed via improvements in Psoriasis Area and Severity Index (PASI) score (with PASI 90 indicating a 90% or greater improvement from baseline PASI score) and a static Physician's Global Assessment (sPGA) response of either 0 or 0 or 1, with dropouts counted as nonresponders. Safety analyses included treatment-emergent adverse events (AEs). RESULTS: At week 52, significantly more ixekizumab-treated patients (P < .01) reported PASI 90 (104 [76.5%]), an sPGA response of 0 (72 [52.9%]), or an sPGA response of 0 or 1 (110 [82.1%]) responses than did ustekinumab-treated patients (PASI 90, 98 [59.0%]; sPGA response of 0, 60 [36.1%]; and sPGA response of 0 or 1, 108 [65.1%]). Treatment-emergent AEs, serious AEs, and discontinuation rates were not different between the treatment groups. Injection site reactions occurred more frequently in the ixekizumab-treated group (ixekizumab, 22 [16.3%]; ustekinumab, 2 [1.2%]) (P < .001). LIMITATIONS: This study was not designed to compare safety end points related to rare events. CONCLUSIONS: Compared with ustekinumab, ixekizumab showed superior efficacy and comparable safety outcomes through 52 weeks of treatment.

Prevalence of genital psoriasis in patients with psoriasis.

BACKGROUND: Psoriatic lesions in the genital area (GenPs) can cause considerable physical and emotional distress. To increase physician awareness, we estimated the GenPs prevalence among patients with psoriasis. METHODS: An English language literature search was performed. Articles reporting GenPs prevalence met the search criteria and were included. Because GenPs is rarely reported in demographics of prospective clinical trials, GenPs prevalence and baseline demographics of patients with and without GenPs in two prospective randomized phase 3b trials (NCT02561806 and NCT02634801) involving patients with moderate-to-severe psoriasis are reported. RESULTS: Overall, 600 references were screened. Eighteen articles met the search criteria. Patient populations were highly heterogeneous across articles. Broadly, the presence of GenPs was either physician-reported (physical examinations) or patient-reported (questionnaires). In the literature, GenPs prevalence at the time of reporting ranged from 7% to 42% and the prevalence of GenPs at any time during the course of psoriasis ranged from 33% to 63%. In the two prospective clinical trials, the prevalence of GenPs at the time of enrollment was 35-42%. CONCLUSION: A substantial proportion of patients experience genital lesions at some time during the course of psoriasis. Increased awareness of GenPs prevalence may drive improved assessment and treatment.
