Brodalumab: 5-Year US Pharmacovigilance Report.

INTRODUCTION: Brodalumab is a human interleukin-17 receptor A antagonist indicated for the treatment of moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy and have failed to respond or have lost response to other systemic therapies. Although the US prescribing information for brodalumab includes a boxed warning regarding suicidal ideation and behavior, no causal association has been demonstrated. Here, we summarize 5 years of pharmacovigilance data, from August 15, 2017, through August 14, 2022, reported to Ortho Dermatologics by US patients and healthcare providers. METHODS: Prevalence of the most common adverse events (AEs) listed in the brodalumab package insert (incidence ≥ 1%) and AEs of special interest are described. Brodalumab exposure was estimated as the time from the first to last prescription-dispensing authorization dates. Data were collected from 4744 patients in the USA, with an estimated exposure of 5815 patient-years. RESULTS: Over 5 years, 11 cases of adjudicated major adverse cardiovascular events were reported (0.23 events/100 patients), a rate lower than that experienced by patients in the international Psoriasis Longitudinal Assessment and Registry. There were 106 serious infections. No serious fungal infections were reported. There were 40 confirmed and 2 suspected COVID-19 cases, with no new COVID-19-related deaths. Of 49 reported malignancies among 42 patients, 3 were deemed possibly related to brodalumab. No completed suicides and no new suicidal attempts were reported. CONCLUSION: Five-year pharmacovigilance data are consistent with the established safety profile reported in long-term clinical trials and previous pharmacovigilance reports, with no new safety signals.

Brodalumab is an injectable treatment approved for moderate-to-severe plaque psoriasis in adults who lacked response to previous treatments. In the USA, brodalumab is only available under a Risk Evaluation and Mitigation Strategy for increased suicidality risks; however, findings from 5 years of real-world safety data have demonstrated a lack of association. In this report, we discuss safety findings reported by US patients and healthcare providers for 4744 patients treated with brodalumab over 5 years. Joint pain (known as arthralgia) was the most common safety finding, with 122 cases reported over 5 years. Other safety findings of interest across 5 years included 106 serious infections (defined as prolonged infections or infections requiring treatment), 54 cases of depression, 49 cases of cancer (in 42 patients), 40 confirmed cases of COVID-19, and 11 cases of major cardiovascular events (such as stroke or heart attack). No completed suicides occurred throughout 5 years, and no new suicidal attempts were reported in year 5. In indirect comparisons with safety data from patients with psoriasis receiving or eligible to receive similar treatments, brodalumab was not associated with an increased risk of serious infection, cancer, major cardiovascular events, or inflammatory bowel disease. Taken together, these data are consistent with safety findings from long-term clinical trials and previous safety reports of brodalumab.

Improvements in Psoriasis-Related Work Productivity with Tildrakizumab: Results from a Phase 4 Real-World Study in Patients with Moderate-to-Severe Plaque Psoriasis.

INTRODUCTION: Plaque psoriasis is a chronic condition that may impact patients' work productivity. Tildrakizumab, an interleukin-23 p19 inhibitor, is approved for treatment of moderate-to-severe plaque psoriasis in adults. However, the effect of tildrakizumab treatment on work productivity in patients with psoriasis is not well characterized. METHODS: In this multicenter, open-label, uncontrolled phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. Patients completed the Work Productivity and Activity Impairment Questionnaire: Psoriasis (WPAI:PSO) at baseline and every 12 weeks from week 16 through week 64. The following four domains of the WPAI:PSO were examined: absenteeism (percentage of time missed from work due to psoriasis), presenteeism (percentage reduction of productivity while at work due to psoriasis), total activity impairment (percentage impairment in activities other than work due to psoriasis), and total work productivity impairment (total percentage of work impairment from both absenteeism and presenteeism due to psoriasis). Missing data were not imputed. RESULTS: Of the 55 patients enrolled, 31 patients completed all domains of the WPAI:PSO at week 64. From baseline to week 64, respectively, mean ± standard deviation (SD) scores improved for presenteeism (20.5 ± 21.7 to 2.6 ± 5.8; P < 0.001), total activity impairment (29.5 ± 26.6 to 4.4 ± 9.4; P < 0.001), and total work productivity impairment (20.9 ± 22.2 to 2.6 ± 5.8; P < 0.001). The mean ± SD score for absenteeism decreased from 1.1 ± 5.7 at baseline to 0.0 ± 0.0 at week 64, but this change was not statistically significant. CONCLUSION: Tildrakizumab treatment mitigated work productivity loss due to psoriasis as measured by the presenteeism, total activity impairment, and total work productivity impairment domains of the WPAI:PSO. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03718299.

Vaccination recommendations for adults receiving biologics and oral therapies for psoriasis and psoriatic arthritis: Delphi consensus from the medical board of the National Psoriasis Foundation.

BACKGROUND: For psoriatic patients who need to receive nonlive or live vaccines, evidence-based recommendations are needed regarding whether to pause or continue systemic therapies for psoriasis and/or psoriatic arthritis. OBJECTIVE: To evaluate literature regarding vaccine efficacy and safety and to generate consensus-based recommendations for adults receiving systemic therapies for psoriasis and/or psoriatic arthritis receiving nonlive or live vaccines. METHODS: Using a modified Delphi process, 22 consensus statements were developed by the National Psoriasis Foundation Medical Board and COVID-19 Task Force, and infectious disease experts. RESULTS: Key recommendations include continuing most oral and biologic therapies without modification for patients receiving nonlive vaccines; consider interruption of methotrexate for nonlive vaccines. For patients receiving live vaccines, discontinue most oral and biologic medications before and after administration of live vaccine. Specific recommendations include discontinuing most biologic therapies, except for abatacept, for 2-3 half-lives before live vaccine administration and deferring next dose 2-4 weeks after live vaccination. LIMITATIONS: Studies regarding infection rates after vaccination are lacking. CONCLUSION: Interruption of antipsoriatic oral and biologic therapies is generally not necessary for patients receiving nonlive vaccines. Temporary interruption of oral and biologic therapies before and after administration of live vaccines is recommended in most cases.

Mechanism of Action of Brodalumab May Correlate With Efficacy in Patients With Inflammatory Skin Diseases.

Biologic therapy is used for systemic treatment of multiple inflammatory conditions, including moderate-to-severe plaque psoriasis. Brodalumab is an interleukin-17 (IL-17) receptor A antagonist indicated for the treatment of moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy and have failed to respond or have lost response to other systemic therapies. The unique mechanism of action of brodalumab, which blocks signaling mediated by multiple IL-17 family members, may play a key role in the overall efficacy, including in patients whose disease did not respond to other biologics. In this narrative review, we discuss the mechanism of action of brodalumab in inflammatory skin conditions, exploring how it relates to clinical and real-world efficacy, rescued responses after IL-17A inhibitor failure, and improvements in mental health and quality of life.

Habit Reversal Therapy for Skin Picking Disorder.

Skin picking disorder is a challenging disease at the intersection of psychiatry and dermatology. Cognitive behavioral therapy (CBT) techniques have been proven to benefit patients with skin picking disorder. However, because patients with skin picking disorder may decline referral to a mental health professional, dermatologists should be aware of techniques based on CBT, such as habit reversal therapy (HRT), and be prepared to implement them in clinical practice to decrease the burden of disease in affected patients.

Integrating Precision Medicine into Medical Dermatology Clinical Practice: An Expert Consensus Panel.

BACKGROUND: Precision medicine utilizes an individual’s genomics to improve diagnosis, prognosis, and therapy. The joint American Academy of Dermatology and National Psoriasis Foundation 2019 guidelines recognized the need to identify biomarkers that can predict the optimal biologic agent for an individual patient. This paper examines the current state of precision medicine in dermatology and how its use can improve outcomes in psoriasis. METHODS: A search of PubMed/MEDLINE using the terms precision medicine, personalized medicine, biomarkers, genomics, and dermatology was performed to identify relevant publications. An expert consensus panel was then convened to assign levels of evidence to each article using strength of recommendation taxonomy and create consensus statements requiring a two-thirds supermajority for agreement utilizing a modified Delphi approach. RESULTS: Thirteen articles met inclusion and exclusion criteria and were assigned levels of evidence. The panel created 10 consensus statements on how precision medicine can improve patient outcomes, all of which received a unanimous (6/6) vote. CONCLUSION: Choosing a biologic medication for psoriasis often relies on patient preference, provider preference, and a trial-and-error approach. Utilizing precision medicine tests such as Mind.Px can help providers identify biomarkers unique to a patient’s pathophysiology and choose the optimal medication through a targeted and evidence-based approach.

National Psoriasis Foundation Telemedicine Task Force guidance for management of psoriatic disease via telemedicine.

Telemedicine emerged as an alternative care delivery system used to offer effective long-term management to patients with chronic, inflammatory conditions such as psoriatic disease. Teledermatology can provide reliable clinical information through thorough history-taking and virtual evaluations that include patient-provided images and disease activity assessment tools that may help accurately diagnose and manage patients with psoriasis. The integration of validated screening tools for psoriatic arthritis and effective teledermatology practices may improve access to specialists, thus avoiding preventable delays in the diagnosis and treatment of patients with psoriatic arthritis. Although the provision of telehealthcare should not completely replace high quality, in-person dermatologic or rheumatologic visits, the convenience and collaborative nature of teledermatology may lead to expanded access and expedited care in the appropriate setting, whether it be in a virtual or in-person visit.

Brodalumab: 4-Year US Pharmacovigilance Report.

Brodalumab is an interleukin-17 receptor A antagonist approved for the treatment of moderate-to-severe psoriasis in adults without response or with loss of response to other systemic therapies. Brodalumab carries a boxed warning in the United States regarding suicidal ideation and behavior, though no causal relationship has been established. Here, we summarize 4 years of pharmacovigilance data, from August 15, 2017, through August 14, 2021, reported to Ortho Dermatologics by US patients and healthcare providers. The most common AEs listed in the brodalumab package insert (incidence ≥1%) and AEs of special interest are described. Brodalumab exposure estimates were calculated using the time between the first prescription-dispensing authorization date and last prescription-dispensing authorization date. Data were collected from 4019 patients with an estimated brodalumab exposure of 4563 patient-years. The most common AE was arthralgia (115 events; 2.52 events per 100 patient-years). No completed suicides and no new suicidal attempts were reported. There were 102 cases with serious infections; however, no serious fungal infections (including no new cases of oral candidiasis) were reported. There were 26 COVID-19 cases, and 3 of the cases with comorbid conditions were fatal. There were no new cases of Crohn’s disease. Of 37 reported malignancies among 32 cases, none were deemed related to brodalumab. Four-year pharmacovigilance data are consistent with the established safety profile reported in long-term clinical trials and 3-year pharmacovigilance data.

How to successfully handle the initial encounter with a delusional infestation patient.

Managing a delusional patient is one of the most challenging situations experienced by dermatologists. This is exacerbated by the scarcity of psychodermatology training offered in residency and similar training programs. A few practical management tips can be easily employed in the initial visit to avoid an unsuccessful encounter. We highlight the most important management and communication techniques needed for a successful first encounter with this traditionally tricky patient population. Topics such as diagnosing primary versus secondary delusional infestation, how to prepare before entering the exam room, how to write the initial patient note, and when is the ideal time to introduce pharmacotherapy are discussed. Tips on preventing clinician burnout and creating a stress-free therapeutic relationship are reviewed.

Comparing the odds of reported depression in psoriasis patients on systemic therapy: a cross-sectional analysis of postmarketing data.

Patients with psoriasis are more likely to experience depression and suicidality compared to non-psoriatic patients, though systemic therapies have been shown to improve depressive symptoms. It is unclear whether or not biologic or oral agents are more effective at improving such depressive symptoms in psoriasis patients, however. We aimed to determine an estimate of the odds of incident depression in psoriasis patients on different systemic therapies by performing a cross-sectional analysis of postmarketing data. The reporting odds ratio (ROR) for 15 different systemic agents was calculated using reports from the Food and Drug Administration Adverse Events Reporting System (FAERS). After excluding brodalumab and apremilast due to high risk of reporting bias, we found oral agents were associated with a significantly higher ROR of depression compared to biologics (OR = 2.42, 95% confidence interval: 1.93-3.04). These results suggest biologics may be more effective at reducing incident depression than oral agents. Future controlled trials are needed to confirm these findings.

Evolving Concepts in Psoriasis: Special Considerations for Patients With Skin of Color, Skin Barrier Dysfunction, and the Role of Adjunctive Skin Care.

BACKGROUND: Despite considerable advances in our understanding of the pathogenesis and treatment of psoriasis, data pertaining to racial/ethnic variations, effects on barrier function, and the potential role of adjunctive skin care are relatively limited. Knowledge gaps in the clinical presentation, quality-of-life impact, and approach to treating psoriasis in patients with skin color contribute to disparities in care. In addition, small studies suggest that using skincare products can reduce psoriasis symptoms, improve barrier function, and result in higher patient satisfaction, yet patients with psoriasis may underuse skincare products. This manuscript seeks to offer insights into these knowledge gaps and their potential treatment implications. METHODS: A structured literature search followed by a panel discussion and an online review process explored best clinical practices in treating psoriasis patients with skin of color and providing expert guidance for skincare use, including gentle cleansers and moisturizers. RESULTS: Racial/ethnic differences in genetic factors, clinical presentation, and disease burden in psoriasis have been reported. Underrecognition of these differences contributes to racial/ethnic health disparities for psoriasis patients in the US. Several studies have shown a greater quality-of-life impact with psoriasis among patients with skin of color. Although the published data are limited, some studies have identified differences in skin barrier properties and suggest a role for adjunctive skin care in the management of psoriasis. CONCLUSION: Further study is needed to understand racial/ethnic population variations in psoriasis and develop strategies to reduce disparities in care. Addressing alterations in skin barrier function observed in psoriasis may help to improve treatment outcomes and patient satisfaction. J Drugs Dermatol. 2022;21(10):1054-1060. doi:10.36849/JDD.7090.

The Koo-Brownstone staging system as a tool to assist in the management of patients with a possible diagnosis of dermatological delusions: an experts suggestion.

BACKGROUND: Delusional infestation (DI) is one of the most challenging situations dermatologists and other dermatology providers may face in their practice. Dermatologists must know how to properly communicate with these patients. The process of acquiring delusional states can be a gradual development and not all delusional patients in dermatology are the same. OBJECTIVE: The objective of this manuscript is to introduce the 'Koo-Brownstone Staging System' for Delusional Infestation (Morgellons disease) with the goal of improving communication and management for these patients. METHODS: This staging system has been derived based on more than three decades of experience of the senior author supported by additional years of experience of the first author. RESULTS: The following stages are presented and explained: formication only (stage 1), overvalued ideation of parasitosis (stage 2), pre-delusional (stage 3), delusional (stage 4) and terminally delusional (stage 5). LIMITATIONS: This staging system has been derived based on expert clinical experience rather than a direct reporting from this patient population themselves. CONCLUSIONS: This staging system will enhance awareness on the part of the health providers to enable them to categorize a given patient, which becomes critical in optimizing communications and management.

Onset of Plaque Psoriasis Treatment Responses With Anti-IL-17/IL-23 Biologic Therapies.

BACKGROUND: The impact of psoriasis on quality of life arises from both physical symptoms, such as pain and pruritus, and the psychosocial effects of the often highly visible lesions. For patients with moderate-to-severe psoriasis seeking amelioration of these symptoms, time to onset of treatment response is an important consideration when determining an appropriate therapeutic approach with their healthcare provider. METHODS: In this review, we discuss the fluidity of the definition of rapid response and time-to-response expectations of patients with psoriasis receiving biologic therapies. Next, we focus on time to response of brodalumab, a human anti–interleukin-17 receptor A monoclonal antibody, in patients with moderate-to-severe psoriasis, as measured by the psoriasis area and severity index and the psoriasis symptom inventory. Brodalumab previously exhibited efficacy and safety in treatment of moderate-to-severe psoriasis in three phase 3 trials (AMAGINE-1/-2/-3), warranting further characterization of its ability to meet patient needs regarding rapidity of treatment response. Finally, we place time to response of brodalumab in the context of the current treatment landscape of biologic therapies for psoriasis (particularly those targeting the interleukin-17/interleukin-23 axis). RESULTS: Direct and indirect comparisons with other interleukin-targeting drugs support brodalumab’s more rapid onset of treatment effects, including skin clearance and relief of itch and pain. CONCLUSION: Brodalumab induces a rapid treatment response in patients with moderate-to-severe psoriasis and may promote earlier improvements in quality of life. J Drugs Dermatol. 2022;21(8):854-860. doi:10.36849/JDD.6791.

Management of delusions of parasitosis: an interview with experts in psychodermatology.

Delusions of parasitosis (DOP), which is also called Morgellons disease or delusional infestation, can be one of the most challenging clinical encounters in a dermatologist's practice. One reason for this is lack of education during dermatology residency and a paucity of resources for the practicing dermatologist such as specialized psychodermatology clinics for these patients. To help close this knowledge gap, an interview was conducted with 3 experts in the field of psychodermatology and their responses were recorded and edited with goal of improving care for patients suffering from DOP by educating the busy, practicing dermatologist. The experts discussed many topics regarding DOP including the difference between primary and secondary DOP, how to build a good rapport with DOP patients, why the condition is seen mostly in older woman, and which medications are effective for treatment. The interview ends with a few high-yield practical treatment tips.

A systematic review on the economic burden of interstitial lung disease and the cost-effectiveness of current therapies.

BACKGROUND: The economic burden of interstitial lung disease (ILD) is unknown, limiting informed resource allocation and planning. We sought to conduct the first systematic review on the direct, indirect, and overall costs associated with ILD and to evaluate the cost-effectiveness of current therapies globally. METHODS: We conducted systematic reviews of ILD disease cost studies and cost-effectiveness analyses (CEAs) using MEDLINE, Embase, and Web of Science databases between 2000 and 2020. We compared ILD costs between countries according to the share of costs towards each country's respective gross domestic product (GDP) per capita. Costs are reported in 2020 USD. RESULTS: We identified 25 disease cost studies and 7 CEAs. The direct medical costs ranged between $1824 and $116,927 annually per patient (median $32,834; 14-180% of GDP per capita in Western countries). The leading drivers of direct costs were inpatient (55%), outpatient (22%), and medication costs (18%), based on pooled estimates. Annual indirect costs ranged from $7149 to $10,902 per employed patient (median $9607; 12-23% of GDP per capita). Among the 7 CEAs, only 1 study (14%) showed an ILD therapy (ambulatory oxygen) was cost-effective compared to best supportive care. CONCLUSION: The direct and indirect costs associated with ILD are consistently high in all countries with available data, with cost-effectiveness profiles of new therapies generally undesirable. Globally, the median total direct cost for ILD equates to 51% of a country's GDP per capita and has been increasing over time.

Pooled Analysis Demonstrating Superior Patient- Reported Psoriasis Treatment Outcomes for Calcipotriene/ Betamethasone Dipropionate Cream Versus Suspension/Gel.

BACKGROUND: Calcipotriene and betamethasone dipropionate (CAL/BDP) cream is a novel treatment of plaque psoriasis based on PAD™ Technology (PAD-cream) designed to improve patient reported treatment satisfaction and quality of life (QoL). METHOD: A pooled analysis of patient reported outcomes from two phase 3, multicenter, randomized, investigator-blind, active, and vehicle-controlled trials evaluating a total of 1271 patients with mild to moderate plaque psoriasis according to the Physician Global Assessment (PGA) scale. Products were applied once daily for 8 weeks. RESULTS: The proportion of patients evaluating their treatment to have improved by 2 grades to clear or very mild disease on the 5-grade Subject Global Assessment (SGA) scale, defined as SGA Success, was significantly higher in the CAL/BDP PAD-cream group compared to active comparator (CAL/BDP suspension/gel) (week 8, 44.2% vs 27.9%, P<0.0001). A Dermatology Life Quality Index (DLQI) score of 0 or 1, indicating no impact of disease on the patient's life, was obtained by 43.8% of patients at week 8 in the CAL/BDP cream group versus 34.2% in the CAL/BDP suspension/gel group (P=0.0005). CAL/BDP PAD-cream demonstrated significantly greater psoriasis treatment convenience compared to CAL/BDP suspension/gel at all studied time points, including questions addressing greasiness of the formulation and overall satisfaction of treatment. CONCLUSION: CAL/BDP PAD-cream is a novel topical treatment for psoriasis, which through PAD™ Technology offers substantial improvement in QoL and treatment satisfaction for patients. Given these data, CAL/BDP PAD-cream may lead to better adherence to treatment, which ultimately could result in better treatment outcomes in clinical practice.
