Secukinumab in patients with moderate-to-severe hidradenitis suppurativa based on prior biologic exposure: an efficacy and safety analysis from the SUNSHINE and SUNRISE phase III trials.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease associated with a substantial disease burden. Secukinumab has previously been reported to have sustained efficacy with a favourable safety profile in patients with moderate-to-severe HS. It is unknown whether prior biologic exposure affects the efficacy and safety of secukinumab. OBJECTIVES: To investigate the efficacy and safety of secukinumab in patients with moderate-to-severe HS based on prior exposure to -biologics. METHODS: This was an analysis of the SUNSHINE and SUNRISE phase III trials of secukinumab in patients with moderate-to-severe HS. Patients were randomized at baseline to receive secukinumab every 2 (SECQ2W) or 4 weeks (SECQ4W), or placebo for 16 weeks. After week 16, patients on the SECQ2W and SECQ4W schedules remained on the same treatment regimen, while patients randomized to placebo were switched to either SECQ2W or SECQ4W up to week 52. Assessments based on prior exposure to biologics included Hidradenitis Suppurativa Clinical Response (HiSCR), abscess and inflammatory nodule (AN) count, flare rates, HS-related pain [numerical rating scale 30 (NRS30)], 55% reduction in the International Hidradenitis Suppurativa Severity Score System (IHS4-55), Dermatology Life Quality Index, EuroQol-5D and safety. RESULTS: Overall, 1084 patients were randomized in the SUNSHINE and SUNRISE trials and included in this analysis; 255 (23.5%) were biologic-experienced [SECQ2W (n = 80); SECQ4W (n = 81); placebo (n = 94)] and 829 (76.5%) were biologic-naïve [SECQ2W (n = 281); SECQ4W (n = 279); placebo (n = 269)]. At week 16, responses were more efficacious for secukinumab than for placebo with regard to HiSCR in patients who were biologic-experienced {SECQ2W 37.0% [odds ratio (OR) 1.60, 95% confidence interval (CI) 0.83-3.08]; SECQ4W 38.8% [OR 1.67, 95% CI 0.86-3.22]; placebo 27.3%} and biologic-naïve [SECQ2W 45.6% (OR 1.64, 95% CI 1.15-2.33); SECQ4W 45.4% (OR 1.61, 95% CI 1.13-2.29); placebo 34.2%]. Similar results were observed for AN count, NRS30 and IHS4-55. The higher response seen at week 16 with secukinumab was sustained, with a trend toward improvement over time, through to week 52 in both subgroups. Additional efficacy was observed for quality-of-life assessments, and no differences in safety between subgroups were observed. CONCLUSIONS: Regardless of prior biologic exposure, secukinumab was efficacious in improving the signs and symptoms of HS. This finding positions secukinumab as the first option in patients who are biologic-naïve, as well as in patients who have previously been treated with other biologic therapy, based on individual patient needs.

Hidradenitis suppurativa (HS) is a chronic skin disease that causes painful boils. HS is common and affects about 0.4% of the world's population. Treating the condition is difficult, but drugs called 'biologics' can help to improve the symptoms. For example, secukinumab is a biologic drug that has been shown to be effective and well-tolerated for the treatment of HS. In this analysis, we investigated whether previous treatment with biologics could affect the effectiveness and tolerability of secukinumab. This analysis included data from two identical clinical trials (called SUNSHINE and SUNRISE) that recruited adult patients with HS who had moderate-to-severe disease. In these trials, patients took secukinumab 300 mg every 2 weeks or every 4 weeks for 1 year, or a placebo for 4 months and then switched to secukinumab until 1 year. At regular intervals, the effectiveness and tolerability of secukinumab were examined and the results were compared between patients who had previously used another biologic and patients who had never used a biologic before. After 16 weeks, patients who took secukinumab had better results than the patients who took a placebo, independent of previous biologic use. Secukinumab was still effective and had improved results over 1 year of treatment in both subgroups. Regardless of whether patients had previously been taking another biologic, secukinumab was just as tolerable as placebo and there were no new safety risks. Our analysis shows that secukinumab is effective and tolerable, regardless of whether patients have previously used another biologic drug.

Effect of Secukinumab and Tumor Necrosis Factor Inhibitors on Humoral Response to BNT162b2 mRNA Vaccine in Patients With Spondyloarthritis Compared to Immunocompetent Controls.

OBJECTIVE: To assess the humoral response to the BNT162b2 mRNA vaccine among patients with spondyloarthritis (SpA) receiving secukinumab (SEC) compared to those receiving tumor necrosis factor inhibitors (TNFi) and immunocompetent controls. METHODS: Consecutive patients with psoriatic arthritis or axial SpA receiving SEC (n = 37) or TNFi (monotherapy, n = 109; + methotrexate [MTX], n = 16), immunocompetent controls (n = 122), and patients with rheumatoid arthritis (RA) receiving TNFi therapy (controls, n = 50) were vaccinated with 2 or 3 doses of the BNT162b2 vaccine. We evaluated humoral response, adverse events, and disease activity, and monitored for breakthrough coronavirus disease 2019 (COVID-19) postvaccination. RESULTS: The 2-dose vaccine regimen induced a comparable seropositive response in all study groups. S1/S2 antibody titers (in binding antibody units/mL; mean [SD]) were higher in the SEC group vs the TNFi + MTX-SpA and TNFi-RA groups (192.5 [68.4] vs 104.6 [46.9], P < 0.001, and 143.1 [81.9], P = 0.004). After 6 months, 96.3%, 96.6%, and 80.9% of the SEC, immunocompetent, and TNFi monotherapy-SpA groups (P = 0.10), respectively; 66.7% of the TNFi + MTX-SpA group (P = 0.03); and 63% of the TNFi-RA group (P = 0.004) remained seropositive. S1/S2 antibody titer decline was steeper in the TNFi groups than the SEC group. After the third dose, 100% of the SpA and immunocompetent and 88.9% of the TNFi-RA (P = 0.25) groups were seropositive. Rate of breakthrough COVID-19 infection was higher in the TNFi groups than in the SEC group (36-37.5% vs 10.8%). No significant between-group differences were observed for postvaccination disease activity and adverse events. CONCLUSION: SEC did not interfere with the immunogenic response to BNT162b2 vaccine in patients with SpA; however, TNFi therapy was associated with lower S1/S2-antibody titers, faster decline, and higher rate of breakthrough infections.

Patient Perspectives on Psoriatic Disease Burden: Results from the Global Psoriasis and Beyond Survey.

BACKGROUND: Patients' understanding of the systemic nature of psoriatic disease (PsD) remains insufficiently explored. OBJECTIVES: The objective of this study was to assess patients' understanding of PsD, associated comorbidities, disease burden, and relationships with healthcare professionals (HCPs). METHODS: Psoriasis and Beyond was a cross-sectional, quantitative online survey conducted in patients with a self-reported, physician-given diagnosis of moderate to severe psoriasis (body surface area [BSA] >5% to <10%, affecting sensitive and/or prominent body parts or BSA ≥10%) at its worst, with/without psoriatic arthritis (PsA). Patients were recruited through online panels by the Institut de Publique Sondage d'Opinion Secteur (Ipsos SA) and patient advocacy groups. RESULTS: Overall, 4,978 respondents with psoriasis completed the online survey from 20 countries across Australia, Asia, Europe, and the Americas; 30% of patients also reported having concomitant PsA. Overall, 69% of patients with psoriasis had heard that their disease was part of a systemic disease, and 60% had heard of the term "psoriatic disease." Despite this, recognition of common manifestations and comorbidities associated with PsD was low. Among psoriasis-only patients (n = 3,490), 38% screened positive using the Psoriasis Epidemiology Screening Tool (PEST), indicative of potential PsA. Overall, 48% of patients reported that their disease had a very large to extremely large effect on quality of life (QoL; Dermatology Life Quality Index [DLQI] score, 11-30); only 13% of patients reported no impact of the disease on QoL (DLQI, 0-1). Most patients had experienced stigma and discrimination (82%) and a negative impact on relationships (81%) in their lives. Overall, 59% of patients were not involved in deciding their treatment goals: 58% of all treated patients (n = 4,757) and 64% of treated patients with concomitant PsA (n = 1,409) were satisfied with their current treatment. CONCLUSIONS: These results highlight that patients may not fully understand the systemic nature of their disease, were frequently uninvolved in deciding treatment goals, and were often not satisfied with their current treatment. Increasing patients' participation in their care can facilitate shared decision-making between patients and HCPs, which may result in better treatment adherence and patient outcomes. Furthermore, these data indicate that policies should be implemented to protect against stigma and discrimination, which are commonly experienced by patients with psoriasis.

Immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination in patients receiving secukinumab: a literature review.

Purpose: There is a paucity of evidence on the impact of immune-mediated inflammatory disease (IMID) treatments on the immunogenicity of SARS-CoV-2 vaccination. The purpose of this literature review is to address the question of whether patients with IMIDs receiving secukinumab, a fully human anti-interleukin-17A monoclonal antibody, have an adequate immune response after SARS-CoV-2 vaccination. Materials and Methods: Clinical studies that evaluated the effect of secukinumab on immune responses in patients with IMIDs after SARS-CoV-2 vaccination were searched in publication databases, including Medline and Embase, until May 2022. Results: From the 53 articles identified, a total of 11 articles were included. Overall, the majority of the patients treated with secukinumab elicited an adequate immune response to SARS-CoV-2 vaccines. Patients receiving secukinumab for IMIDs developed cellular immune responses following vaccination with the BNT162b2 vaccine, and there were no significant differences in the overall humoral and cellular immune responses between patients and healthy individuals. The third dose of the BNT162b2 mRNA vaccine resulted in a positive antibody response in secukinumab-treated patients. Conclusion: The available data provide no evidence of impairment in immunological response to SARS-CoV-2 vaccines by secukinumab in patients with IMIDs.

Exploring disease comorbidities and temporal disease progression of psoriasis: an observational, retrospective, multi-database, cohort study.

BACKGROUND: Comorbidities associated with psoriasis are well documented. However, few studies have explored the comorbidity trajectories that patients with psoriasis commonly experience over time. This study reports the 5-year comorbidity trajectories of patients with psoriasis. OBJECTIVES: To determine the long-term comorbidity trajectories of patients with psoriasis in Denmark. METHODS: This observational cohort study explored the Danish National Patient Registry (DNPR) between 1999 and 2013 to identify comorbidities diagnosed 5 years prior to or after a psoriasis diagnosis. Comorbidity occurrence in patients with psoriasis (psoriasis cohort) was compared with patients without psoriasis (the N group). Comparison groups, each the same size as the psoriasis cohort, were created by selecting random patients from the N group. If a comorbidity occurrence was higher in more than nine comparison groups than in the psoriasis cohort, it was not analysed and only comorbidities that occurred in ≥ 0·8% of the psoriasis cohort were analysed. The strength of association between a psoriasis diagnosis and a comorbidity diagnosis was measured using relative risk (RR). All psoriasis and comorbidity pairs that achieved RR > 1 (P < 0·001) (known as a Diagnosed Pair) were tested for directionality to identify the sequence of diagnoses using a binomial test. Diagnosed Pairs with a statistically significant direction (Bonferroni corrected P-value < 0·025) were then used to create comorbidity trajectory clusters 5 years before and after a psoriasis diagnosis. RESULTS: A total of 17 683 patients with psoriasis were compared with 10 000 comparison groups. A total of 121 comorbidities met the minimum criteria that ≥ 0·8% of the psoriasis cohort were diagnosed with the comorbidity within 5 years (before or after) of their psoriasis diagnosis. Thirty-eight of these comorbidities achieved RR > 1 (P < 0·001) with psoriasis, of which 19 achieved a significant direction from psoriasis to a comorbidity (including psoriasis to hypothyroidism), and four achieved a significant direction from a comorbidity diagnosis to a psoriasis diagnosis (including Crohn disease to psoriasis); four of five comorbidity trajectories with three sequential diagnoses achieved an RR > 1 (P < 0·001) and a significant direction from psoriasis to the first comorbidity to the second comorbidity (including psoriasis to hypertension to atrial fibrillation and flutter). CONCLUSIONS: Comorbidity trajectories may support clinicians in conducting disease risk analyses of patients with psoriasis and help plan optimal treatment to prevent future high-risk comorbidities.

A nationwide population-based cohort study of the incidence of severe and rare infections among adults with psoriasis in Denmark.

BACKGROUND: Patients with psoriasis have a high risk for multiple comorbid conditions. However, few studies have examined the association between psoriasis and severe and rare infections. This study reports the incidence of severe and rare infections (considered as rare in Denmark) among Danish patients with psoriasis, compared with the general population. OBJECTIVES: The objectives of this study were to assess the incidence and risk of severe and rare infections in Danish patients with psoriasis and the matched general population, and to compare this risk for patients with severe or mild psoriasis with that of the general population. METHODS: Data for individuals aged ≥18 years who were alive and resident in the source population were collected from the Danish National Patient Register between 1 January 1997 and 31 December 2018. Individuals with any of the investigated chronic infections prior to inclusion were excluded. Patients with psoriasis were matched (1 : 6) for age and sex with general population controls. Severe infections were defined as infections requiring treatment in a hospital setting and rare infections included HIV, hepatitis B and C, and tuberculosis infections. Incidence rates (IRs) were reported per 100 000 person-years of exposure. Severe psoriasis was defined according to previous or active use of systemic or biological treatment. Patients who never received biological and/or systemic treatment were categorized as having mild psoriasis. RESULTS: A total of 94 450 patients with psoriasis were matched with 566 700 controls. The respective IRs were higher for patients with any psoriasis compared with controls; IR 3104·9 [95% confidence interval (CI) 3066·6 to 3143·7] and IR 2381·1 (95% CI 2367·6 to 2394·6) for any infection, IR 3080·6 (95% CI 3042·5 to 3119·3) and IR 2364·4 (95% CI 2350·9 to 2377·9) for severe infections, and IR 42·9 (95% CI 38·89 to 47·4) and IR 31·8 (95% CI 30·34 to 33·3) for rare infections, respectively. Patients with severe psoriasis had higher IRs of severe or rare infections (IR 3847·7, 95% CI 3754·3 to 3943·4) compared with patients with mild psoriasis and controls. CONCLUSIONS: As the severity of psoriasis increases, so does the risk of severe and rare infections. Therefore, clinicians should be aware of the increased risk of severe and rare infections in patients with severe psoriasis so that early investigation and treatment can be initiated. What is already known about this topic? Few studies have looked at the incidence and prevalence of serious infections (associated with hospitalization) and rare infections including tuberculosis, hepatitis B and C, and HIV among patients with different severities of psoriasis. What does this study add? Patients with psoriasis have an increased risk of severe and rare infections. Clinicians should be aware of the increased risk of severe and rare infections in patients with severe psoriasis so that early investigation and treatment can be initiated.

Impact of Psoriatic Disease on Quality of Life: Interim Results of a Global Survey.

INTRODUCTION: Psoriatic disease (PsD) is a chronic systemic disorder affecting numerous body areas, including skin and joints. Patients' perspectives regarding understanding their disease and dialogue with healthcare professionals (HCPs) on treatment strategies is becoming increasingly important in the holistic management of PsD. The study aim was to determine patients' understanding of the systemic nature of psoriasis and psoriatic arthritis (PsA) and the associated burden of living with these diseases. The relationship between patient and HCP was also evaluated. METHODS: Psoriasis and Beyond: The Global Psoriatic Disease Survey was a cross-sectional, quantitative online survey, conducted in patients with moderate to severe plaque psoriasis with or without concomitant PsA. Here, we report interim analysis results. RESULTS: A total of 1678 respondents from 11 countries were included. Overall, 31% of patients with psoriasis reported concomitant PsA, 80% of whom considered their PsA severity as moderately or highly active. In total, 63% of patients had heard the term "psoriatic disease". Few patients were aware of psoriasis manifestations (PsA, 29%; axial symptoms, 18%) or comorbidities (obesity, 21%; cardiovascular disease, 18%). Among patients with psoriasis and concomitant PsA, 70% reported swollen and tender joints, especially of the finger(s) and/or toe(s). Most patients (84%) experienced stigma and discrimination and reported a negative impact of their disease on work, emotions, and relationships. Overall, 42% of patients had never discussed treatment goals with their HCP. Patients who were dissatisfied with their current treatment (psoriasis, 15%; psoriasis with PsA, 14%) reported incomplete relief of skin symptoms (57%) and joint symptoms (45%) as primary reasons for dissatisfaction. CONCLUSIONS: Despite many patients having heard the term "psoriatic disease", the majority were unaware of the systemic nature and increased risk of comorbidities associated with PsD. This interim analysis highlights the need for patient education, productive patient-HCP dialogue, and shared decision-making in optimal disease management.

Association Between Confocal Morphologic Classification and Clinical Phenotypes of Multiple Primary and Familial Melanomas.

Importance: The improved knowledge of clinical, morphologic, and epidemiologic heterogeneity of melanoma in the context of multiple primary and familial melanomas may improve prevention, diagnosis, and prognosis of melanoma. Objective: To characterize reflectance confocal microscopy (RCM) morphologic patterns of melanomas in multiple primary and familial melanomas. Design, Setting, and Participants: In this cross-sectional, retrospective study, patients in a hospital-based referral center were recruited from March 1, 2010, through August 31, 2013; data analysis was conducted from September 1, 2013, through May 31, 2014. Consecutive primary melanomas, documented by dermoscopic and confocal examination, from multiple primary and familial melanomas with known CDKN2A mutational status were studied. Main Outcomes and Measures: Epidemiologic, genetic, dermoscopic, and histologic data were evaluated according to an RCM morphologic classification: dendritic cell, round cell, dermal nest, combined, and nonclassifiable types. Results: Fifty-seven melanomas from 50 patients (28 women [56%] and 49 white patients [98%]) were included: 23 dendritic cell (40%), 21 round cell (37%), 2 dermal nests (4%), 2 combined (4%), and 9 nonclassifiable (16%). The median (SD) age of the participants was 53.0 (16.9) years (interquartile range, 41.8-71.2 years), and the median (SD) age at the first melanoma was 46.0 (17.1) years (interquartile range, 35.8-61.5 years). Dendritic cell melanoma was characterized by older age at diagnosis, phototypes 2 and 3, more intense solar exposure, and moderate to severe solar lentigines; it was the most prevalent confocal type in facial lesions and was associated with the lentigo maligna histologic subtype. Round cell melanomas were identified more often in the familial context and in individuals with phototype 1 skin types; RCM features, such as junctional thickening, dense dermal nests, and nucleated cells within papillary dermis, were more frequently found in this subtype. Dermal nest and combined melanoma were associated with the absence of pigmented network on dermoscopy and thicker tumors on histologic analysis. Nonclassifiable type was associated, by RCM, with the absence of pagetoid cells on confocal examination and lower frequency of marked atypia on melanocytes in the basal cell layer; it presented with lower ABCD Total Dermoscopy Scores and RCM scores compared with the other types. CDKN2A mutation carriers may develop any RCM type of melanoma. Conclusions and Relevance: Different routes to develop melanoma can be identified according to RCM morphologic classification, with dendritic cell melanomas being associated with chronic sun damage and round cell melanoma with early age at onset and phototype 1 in the context of multiple primary and familial melanomas. The morphologic expression of melanomas via dermoscopy and confocal examination varies according to differences in tumor stage and biological behavior.

New Topical Treatment Options for Actinic Keratosis: A Systematic Review.

This systematic review compared the relative efficacy of 5-fluorouracil 0.5% in salicylic acid 10% (5-FU/SA), ingenol mebutate (IMB) and imiquimod 2.5%/3.75% (IMI) for actinic keratosis on the face, forehead or scalp. Only 11 publications, relating to 7 randomised controlled trials, met inclusion criteria and it was only possible to compare the effect of all 3 treatments on complete clinical clearance, and the effect of 5-FU/SA and IMB on actinic keratosis recurrence rate. Despite a higher vehicle response rate for 5-FU/SA, complete clinical clearance was higher than IMB and IMI (55.4, 42.2, and 25.0-30.6/34.0-35.6%, [corrected] respectively). 5-FU/SA was also associated with lower actinic keratosis recurrence rate than IMB at 12 months post-treatment (32.7 vs. 53.9%). Although qualitative assessment suggested a numerical advantage of 5-FU/SA over IMB and IMI in terms of complete clinical clearance and sustained clearance, clinical data from longer term trials, with comparable outcome measures, are required to corroborate these findings.

In vivo reflectance confocal microscopy characterization of field-directed 5-fluorouracil 0.5%/salicylic acid 10% in actinic keratosis.

Actinic keratosis (AK), a frequently diagnosed cutaneous neoplasm in individuals with chronic sun exposure or fair skin, is a risk factor for squamous cell carcinoma. AK presents as clinically visible lesions and/or as subclinical lesions where an entire field of area (field cancerization) contains lesions of various grades. The diagnosis and surveillance of subclinical AK is challenging. We report a new AK management approach, including subclinical AK, with noninvasive in vivo reflectance confocal microscopy (RCM) monitoring of field-directed topical 5-fluorouracil 0.5%/salicylic acid 10.0% (5-FU/SA; currently approved for single lesions). In this case series, eight patients with primarily recurrent, multiple AKs received ≤ 6 weeks of field-directed 5-FU/SA; complete clearance of clinical/subclinical AKs on various body areas was shown in most patients using RCM. RCM facilitated the detection/characterization of subclinical AKs in the setting of field cancerization. Topical field-directed 5-FU/SA monitored with RCM is a promising management approach for subclinical AKs.

In vivo reflectance confocal microscopy to monitor the response of lentigo maligna to imiquimod.

BACKGROUND: Imiquimod has been used for treating lentigo maligna (LM) in selected cases when surgery is not an appropriate option because of functional or aesthetic impairment. Reflectance confocal microscopy (RCM) is a noninvasive method that has not been validated for monitoring the treatment of LM with imiquimod. OBJECTIVE: We sought to evaluate the use of in vivo RCM to accurately monitor the response of LM to nonsurgical treatment with topical imiquimod. METHODS: Twenty patients with confirmed facial LM, not amenable to surgical treatment or radiation therapy, were included prospectively. Clinical evaluation was performed by dermoscopy, RCM, and histopathology. Patients applied imiquimod 5% for 8 weeks. The affected area was assessed using the previously described LM score on RCM, and target sample biopsies were performed to confirm or discard RCM findings. RESULTS: Fifteen of the 20 patients (75%) presented histologic tumor clearance. Confocal microscopy identified 70% of these responders with no false-negative results, and when compared with histopathology, there was no significant difference in evaluating the response to imiquimod. LIMITATIONS: The impossibility of examining the entire lesion by means of histopathology is a limitation. CONCLUSION: In vivo RCM evaluation was useful in accurately monitoring the response of LM to nonsurgical treatment with topical imiquimod in patients when surgery is contraindicated.

In vivo confocal microscopy features of cutaneous leishmaniasis.

BACKGROUND: Cutaneous leishmaniasis is widely distributed, Spain being a hypoendemic region. Noninvasive bedside detection of the histopathologic response to the intracellular organism that allows rapid diagnosis and prompt therapy could be the ideal tool to manage a commonly self-healing lesion. Confocal microscopy is a technique which allows in vivo examination of the skin at cellular resolution. METHODS: We describe the in vivo confocal microscopic features of cutaneous leishmaniasis, finding a correlation with dermoscopy and histopathology. CONCLUSIONS AND RELEVANCE: This case illustrates the capability of confocal microscopy to characterize the cutaneous infection by Leishmania organisms and to perform a noninvasive diagnosis.

Dermoscopic rosettes as a clue for pigmented incipient melanoma.

The rosette structure is a dermoscopic sign visible under polarized light, characterized by 4 white points arranged as a 4-leaf clover. It has been mainly described in facial sun-damaged skin and actinic keratosis, although it has also been found in squamous and basal cell carcinomas, and in 2 cases of hypomelanotic melanomas. We describe 2 different cases of pigmented incipient melanomas with the presence of multiple rosettes and shiny white structures on dermoscopy. In the reflectance confocal microscope they exhibit a disarranged epidermal architecture with atypical and dendritic cells. Histological examination showed focal hyperkeratosis and a normal corneal layer presented alternatively. To our knowledge this is the first description of rosette structures in pigmented melanomas. Based on a proper dermoscopic- confocal-histopathological correlation, we hypothesize that rosettes could correspond to optic phenomena due to changes in the superficial epidermal reaction and in the acrosyringia.
