Psoriasis

A significant proportion of patients with moderate to severe plaque psoriasis achieved at least a 75% improvement in the Psoriasis Area and Severity Score (PASI 75) compared with those on placebo after 12 weeks of treatment with an investigational oral tyrosine kinase 2 (TYK2) inhibitor, in a phase 2 study presented during a late breaker presentation at the annual meeting of the American Academy of Dermatology.

ESK-001 is a highly-selective TYK2 inhibitor that “reduces signaling through several cytokine receptors including receptors for interleukin (IL)-12, IL-23, and interferon (IFN)-alpha,” according to Alumis, the company developing ESK-001.

The STRIDE trial enrolled 228 adults (mean age, 48 years) with a mean PASI score of 17.8 at baseline, randomized to one of five doses of ESK-001, or placebo. Nearly 70% of those enrolled were men, 82.5% were White, nearly 6% were Asian, and about 4% were Black.

The proportion of patients achieving at least a PASI-75 at 12 weeks, the primary endpoint, ranged from 19.4% among those on the lower dose (10 mg a day) to 56.4% among those on 20 mg twice a day and those on 40 mg once a day, and 64.1% among those on 40 mg twice a day, the highest dose evaluated, compared with 0% of those on placebo.

In addition, 38.5% and 15.4% of those on the highest dose achieved a PASI 90 and PASI 100, respectively, at 12 weeks, according to results presented at the meeting by Kim A. Papp, MD.

Improvements in static Physician’s Global Assessment (sPGA) scores, a secondary endpoint, at 12 weeks were also observed; including 59% of those on the highest dose (40 mg twice a day) achieving an sPGA of 0/1 at 12 weeks, according to Dr. Papp, president of Probity Medical Research, in Waterloo, Ontario, and a study investigator.

Treatment was “generally safe and well tolerated” at all doses, and most treatment-emergent adverse events were “mild to moderate” and self-limited, he said.

The most frequent treatment emergent adverse events included headache and nasopharyngitis (also reported in the placebo group), and upper respiratory tract infections. No cases of treatment-related serious adverse events were reported, and there were no cases of MACE (major adverse cardiovascular events), serious infections, thromboses related to treatment, or lab or ECG findings of concern.

In an ongoing open label extension study, 165 patients on 40 mg once a day and those on 40 mg twice a day are continuing to be evaluated, and at week 16, have continued to show significant efficacy, with a favorable risk-benefit profile to date, according to Dr. Papp.

ESK-001 is also being evaluated in a phase 2b study of patients with systemic lupus erythematosus, and a phase 2 proof-of-concept study of patients with non-infectious uveitis, according to Alumis.

In addition to being an investigator for Alumis, Dr. Papp disclosed serving as an adviser, consultant, investigator, and/or speaker for multiple other pharmaceutical companies.

TOPLINE:

Combined pediatric dermatology-rheumatology clinics can improve patient care and patient satisfaction, a survey of dermatologists suggested.

METHODOLOGY:

• Combined pediatric dermatology-rheumatology clinics can improve patient outcomes and experiences, particularly for pediatric autoimmune conditions presenting with both cutaneous and systemic manifestations.
• The researchers surveyed 208 pediatric dermatologists working in combined pediatric dermatology-rheumatology clinics.
• A total of 13 member responses were recorded from three countries: 10 from the United States, two from Mexico, and one from Canada.

TAKEAWAY:

• Perceived benefits of combined clinics were improved patient care through coordinated treatment decisions and timely communication between providers.
• Patient satisfaction was favorable, and patients and families endorsed the combined clinic approach.
• Barriers to clinic establishment included differences in the pace between dermatology and rheumatology clinic flow, the need to generate more relative value units, resistance from colleagues, and limited time.
• Areas that needed improvement included more time for patient visits, dedicated research assistants, new patient referrals, additional patient rooms, resources for research, and patient care infrastructure.

IN PRACTICE:

The insights from this survey “will hopefully inspire further development of these combined clinics,” the authors wrote.

SOURCE:

The investigation, led by Olga S. Cherepakhin, BS, University of Washington, Seattle, Washington, was published in Pediatric Dermatology.

LIMITATIONS:

Limitations included the subjective nature, lack of some information, selection bias, and small number of respondents, and the survey reflected the perspective of the pediatric dermatologists only.

DISCLOSURES:

The study was supported by the National Center for Advancing Translational Sciences of the National Institutes of Health. One author reported full-time employment at Janssen R&D, and the other authors had no disclosures.

The US Food and Drug Administration (FDA) has approved the biosimilar ustekinumab-aekn (Selarsdi) for the treatment of moderate to severe plaque psoriasis and psoriatic arthritis in adults and pediatric patients aged 6 years or older.

This is the second ustekinumab biosimilar approved by the regulatory agency and is the second biosimilar approval in the United States for the Icelandic pharmaceutical company Alvotech in partnership with Teva Pharmaceuticals. 

Ustekinumab (Stelara) is a human monoclonal antibody targeting interleukin (IL)–12 and IL-23. The drug, manufactured by Johnson & Johnson, totaled nearly $7 billion in sales in 2023 alone, according a press release. 

“Bringing Selarsdi to market in the US early next year presents a significant opportunity to improve patient access to a vital biologic in inflammatory disease and contribute to the reduction of inflationary pressure in healthcare costs,” the chairman and CEO of Alvotech said in the release. 

The first ustekinumab biosimilar, ustekinumab-auub (Wezlana), was approved by the FDA in on October 31, 2023 and is interchangeable with the reference product. This allows pharmacists to substitute the biosimilar for the reference product without involving the prescribing clinician (according to state law). Besides psoriasis and psoriatic arthritis, ustekinumab-auub was also approved for treating moderate to severely active Crohn’s disease and ulcerative colitis. Ustekinumab-aekn does not have an interchangeability designation and was not approved for Crohn’s disease or ulcerative colitis. 

The approval of ustekinumab-aekn was based on two clinical studies. A randomized, double blind, multicenter, 52-week study of 581 patients with moderate to severe plaque psoriasis demonstrated that the biosimilar was as effective as the reference product, with equivalent safety and immunogenicity profiles. A phase 1, randomized, double-blind, single-dose, parallel-group, three-arm study also compared the pharmacokinetic profile of the biosimilar to ustekinumab in 294 healthy adults.

Ustekinumab-aekn is expected to be marketed in the United States on or after February 21, 2025 per a settlement and license agreement with Johnson & Johnson.

Tumor necrosis factor (TNF)-alpha inhibitors are used to treat a variety of autoimmune conditions including psoriasis, psoriatic arthritis, rheumatoid arthritis (RA), spondyloarthritis, and inflammatory bowel disease (IBD). Interestingly, they have also been observed to cause paradoxical psoriasis with an incidence between 0.6%-5.3%, most commonly occurring in patients with underlying Crohn’s disease and rheumatoid arthritis (RA). Infliximab is the most common TNF inhibitor associated with this condition (52.6%-62.6% of cases) followed by etanercept (12%-29%). TNF inhibitor-induced psoriasis most often presents as plaque or palmoplantar psoriasis, but other subtypes have also been documented.

Psoriasis is traditionally divided into two types. Patients with type I psoriasis have a family history, develop symptoms before the age of 40 and are often positive for HLA-Cw6. Type II psoriasis is not related to HLA-Cw6, lacks a family history, and typically manifests after age 40. Psoriatic lesions are well-defined, erythematous plaques with silvery scales most commonly appearing on extensor surfaces and the scalp. Variants include nail psoriasis, pustular psoriasis, inverse psoriasis, and guttate psoriasis.

Although psoriasis is typically a clinical diagnosis, histologic examination may be used to differentiate from other dermatoses if necessary. The lesions of TNF inhibitor-induced psoriasis characteristically display patterns similar to primary psoriasis, including parakeratosis, microabscesses, and rete ridges. Eosinophilic hypersensitivity reactions and features overlapping with eczematous hypersensitivity (psoriasiform dermatitis) may also be present.

The pathogenesis of this condition is not well understood, but theories include a variety of immune processes including interferon overproduction, interleukin and T-cell activation, and the presence of an infectious nidus. Classical psoriasis is related to type 1 interferon release, so theoretically, immunosuppression caused by TNF inhibitor treatment may permit uncontrolled production of interferons, resulting in psoriatic lesions. Another theory is that interleukin (IL)-23, a pro-inflammatory cytokine, promotes activation of T-helper 17 (Th17) cells. Th17 cells are part of the pathogenesis of primary psoriasis and other inflammatory conditions, such as RA and inflammatory bowel disease. Of note, individuals with gastrointestinal inflammatory diseases are already known to be at a greater risk for developing psoriasis. Immunosuppression caused by a TNF inhibitor may leave patients more susceptible to other infections, which may induce psoriatic plaques.

BiluMartin_Donna_FLORIDA_web.jpg

There are multiple approaches to treatment depending on the severity of the disease. If the psoriatic eruption is mild, the medication may be continued. This “treat-through” method is often considered when stopping the current immunotherapy would cause the patient significant issues. Moderate to severe cases of TNF inhibitor-induced psoriasis may warrant switching TNF inhibitor therapy or completely changing the drug class used in the treatment of the underlying autoimmune condition. Additional treatments include topical and oral steroids, UV therapy, methotrexate, cyclosporine, and acitretin.

The Diagnosis: Hypertrophic Lichen Planus

Two biopsies from the left lateral foot revealed hyperkeratosis, wedge-shaped hypergranulosis, irregular acanthosis, and a bandlike lymphocytic infiltrate in the superficial dermis with a classic sawtooth pattern of the rete ridges (Figure 1). Based on the clinical findings and histopathology, the patient was diagnosed with hypertrophic lichen planus (LP) and was treated with clobetasol ointment 0.05%, which resulted in progression of the symptoms. She experienced notable improvement 3 months after adding methotrexate 12.5 mg weekly (Figure 2).

Lichen planus is an idiopathic chronic inflammatory condition of the skin and mucous membranes that classically manifests as pruritic violaceous papules and plaques, which commonly are found on the wrists, lower back, and ankles.¹ The most common variants of LP are hypertrophic, linear, mucosal, actinic, follicular, pigmented, annular, atrophic, and guttate.² The clinical presentation and biopsy results in our patient were consistent with the hypertrophic variant of LP, which is a chronic condition that most often manifests on the lower legs, especially around the ankles, as hyperkeratotic papules, plaques, and nodules.^2,3 The exact pathophysiology of hypertrophic LP is unknown, but there is evidence that the immune system plays a role in its development and that the Koebner phenomenon may contribute to its exacerbation.⁴ There is a well-known association between LP and hepatitis. Patients with chronic LP may develop squamous cell carcinoma.⁴ The variants of LP can overlap and do not exist independent of one another. Recognizing the overlap in these variants allows for earlier diagnosis and therapeutic intervention of the disease process to limit disease progression and patient clinic visits and to improve patient quality of life.

The differential diagnosis for hyperkeratotic plaques of the feet and ankles can be broad and may include keratosis lichenoides chronica, palmoplantar keratoderma, palmoplantar psoriasis, or lichen amyloidosis. These conditions are classified based on various criteria that include extent of disease manifestations, morphology of palmoplantar skin involvement, inheritance patterns, and molecular pathogenesis.⁵ Keratosis lichenoides chronica is a rare dermatosis that presents as a distinctive seborrheic dermatitis–like facial eruption. The facial eruption is accompanied by violaceous papular and nodular lesions that appear on the extremities and trunk, typically arranged in a linear or reticular pattern.⁶ Palmoplantar keratoderma represents a group of acquired and hereditary conditions that are characterized by excessive thickening of the palms and soles.⁵ Palmoplantar psoriasis is a variant of psoriasis that affects the palms and soles and can manifest as hyperkeratosis, pustular, or mixed morphology.⁷ Lichen amyloidosis is a subtype of primary localized cutaneous amyloidosis that manifests as multiple pruritic, firm, hyperpigmented, hyperkeratotic papules on the shins that later coalesce in a rippled pattern.^8,9

The first-line treatment for hypertrophic LP is topical corticosteroids. Alternative therapies include mycophenolate mofetil, acitretin, and intralesional corticosteroid injections.⁴ Treatment is similar for all of the LP variants.

The Food and Drug Administration (FDA) has approved spesolimab-sbzo, an interleukin (IL)-36 receptor antagonist, for the treatment of generalized pustular psoriasis (GPP) in adults and in pediatric patients aged ≥ 12 years who weigh ≥ 40 kg, according to an announcement from the manufacturer. 

This is an expanded indication for spesolimab-sbzo, first approved in September 2022 for treating GPP flares. Developed by Boehringer Ingelheim and marketed under the name Spevigo, the product is an injectable antibody that blocks the IL-36 receptor, a key part of the pathway shown to be involved in the cause of GPP, which is rare and is a potentially-life-threatening disease.

[embed:render:related:node:266450]

According to a press release from the company, the FDA’s approval of the expanded indication was based on the results of a 48-week clinical trial of 123 patients (Effisayil 2), which showed that individuals who received spesolimab experienced a significant 84% reduction in GPP flares compared with those who received placebo. Among 30 study participants who received a high treatment dose, no flares were observed after week 4. Among all patients who received spesolimab-sbzo, treatment was associated with an increased incidence (defined as ≥ 9 cases per 100 patient-years) of injection site reactions, urinary tract infections, arthralgia, and pruritus compared with placebo. 

Spesolimab-sbzo is currently available in 48 countries, according to the Boehringer Ingelheim release, which states that the approval makes it the first targeted therapy that is available for the acute and chronic treatment of patients with GPP.

SAN DIEGO — Home-based phototherapy is non-inferior to office-based phototherapy for the treatment of plaque and guttate psoriasis across all skin types and was associated with improved Physician’s Global Assessment (PGA) and Dermatology Life Quality Index (DLQI) scores, results from a pragmatic, multicenter study showed.

“In 2024, we have a lot of ways to treat moderate-to-severe psoriasis, and phototherapy remains relevant,” lead investigator Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania in Philadelphia, told attendees of a late-breaking abstract session at the annual meeting of the American Academy of Dermatology. 

144542_Gelfand_Joel_web.JPG

“Office phototherapy is 10 to 100 times less expensive than biologics for psoriasis, and in head-to-head trials, it’s about as effective as adalimumab and achieves better patient-reported outcomes. It may have some cardiovascular benefits by lowering IL-6 and improving HDL-P,” he said. “And, compared to secukinumab, it has no risk of infection.”

Although phototherapy is a preferred as a treatment by patients with psoriasis, he continued, inconvenience of traveling to a clinician’s office for the treatment and lack of coverage by health insurance plans remain major barriers to this option. According to Dr. Gelfand, office-based phototherapy is not available in 90% of counties in the United States, “and a lack of US data has resulted in many insurance companies not covering home phototherapy. As a result, many providers are uncertain about prescribing it.”
 

LITE Study Data

In 2019, Dr. Gelfand and colleagues Light Treatment Effectiveness (LITE) study, a patient-centered study that tested the hypothesis that narrowband UVB phototherapy of psoriasis at home is non-inferior to office treatment, based on outcomes that matter to patients, clinicians, and payers. The co-primary outcomes were a PGA score of 0/1 (clear, almost clear) and a DLQI score of 5 or less (small, no effect on health-related quality of life).

Dr. Gelfand and colleagues at 42 sites in the United States enrolled 783 patients aged 12 years and older who had plaque or guttate psoriasis and were candidates for phototherapy at home or in an office setting. New or established patients to the practices were accepted into the trial, while those treated with phototherapy within 14 days before the baseline visit were not. These entry criteria “are highly pragmatic and reflect routine clinical practice,” he said.

The researchers evenly stratified patients by skin types I and II, III and IV, and V and VI. They collected data from medical records or from an app on the patient’s cell phone, which captured the DLQI data. Study participants were randomly assigned 1:1 to office- or home-based phototherapy for 12 weeks at doses recommended in the 2019 AAD-National Psoriasis Foundation guidelines. This was followed by a 12-week observation period, which ended at 24 weeks. 

At baseline, the mean DLQI score of patients was 12.2, the mean PGA score was 3, and their mean body surface area affected was 12.5%. “These patients had pretty severe disease, long-standing disease, and about 12% were on biologics or nonbiologic systemic therapy during the study,” said Dr. Gelfand, also the director of the Psoriasis and Phototherapy Treatment Center at Penn. In addition, he said, “the average round-trip to receive phototherapy in the office was about 60 minutes.”
 

An Improvement in Health Equity

Following treatment at 12 weeks, 25.6% of patients in the office-based phototherapy group achieved a PGA of 0/1, compared with 32.8% of patients in the home-based phototherapy group (P >.0001 for non-inferiority). Similarly, 33.6% of patients in the office-based phototherapy group achieved a score of 5 or less on the DLQI, compared with 52.4% of patients in the home-based phototherapy group (P >.0001 for non-inferiority).

In subgroup analyses, patients with darkly pigmented skin did especially well on home phototherapy relative to office treatment. “This finding is an example of how the LITE study was specifically designed to improve health equity through an intentionally inclusive approach,” Dr. Gelfand said. Perhaps not surprisingly, patients in the home-based phototherapy arm were more adherent to treatment compared with those in the office-based arm (a mean of 26.8 sessions during the study period, compared with a mean of 17.9, respectively; P < .0001). “They also had higher cumulative doses of phototherapy and therefore higher episodes of treatments with erythema,” he noted.

Among patients who reported “itchy, sore, painful, or stinging” skin in the previous week, 63% characterized the degree of discomfort as “not at all or a little,” while 28% said “a lot,” and 9% said “very much.” No patients withdrew or stopped phototherapy during the trial because of treatment-related side effects, “so it’s very well tolerated,” Dr. Gelfand said.

[embed:render:related:node:268074]

“If a patient never had phototherapy before, they did just as well at home as they did in the office. This suggests that there’s no reason to insist that a patient use office-based phototherapy before using home phototherapy.”

The researchers studied the efficacy of narrow-band UVB in patients who had at least two treatments per week for 12 weeks. In this subgroup of patients, 60% achieved clear or almost clear skin and nearly 50% achieved the equivalent of a Psoriasis Area and Severity Index (PASI) 90 score.

“Home phototherapy is clearly non-inferior to office-based phototherapy across all skin types and both primary outcomes, PGA and DLQI, and both have excellent effectiveness and safety in real-world settings,” Dr. Gelfand concluded. “These data support the use of home phototherapy as a first-line treatment option for psoriasis, including those with no prior phototherapy experience.”

LITE Study Described as “Groundbreaking”

One of the session moderators, dermatologist Andrew Blauvelt, MD, MBA, of the Oregon Medical Research Center, Portland, asked about the impact that lockdowns during the early phase of the COVID-19 pandemic had on the trial. “The study shut down for a couple weeks during the initial lockdown, but we got back up and running pretty quickly,” Dr. Gelfand responded. “We didn’t study that specific period of time, but the study was going on well before COVID and well after COVID restrictions were lifted. We’ll have to analyze that period of time you question but I suspect that it’s not driving the results we see.”

Asked to comment, Henry W. Lim, MD, a dermatologist with Henry Ford Health in Detroit, characterized the findings of the study as “groundbreaking, because it looked at a real-life situation in the use of phototherapy at home vs in the office, showing that the home phototherapy is not inferior to office-based phototherapy.”

“If a patient never had phototherapy before, they did just as well at home as they did in the office. This suggests that there’s no reason to insist that a patient use office-based phototherapy before using home phototherapy.”

The researchers studied the efficacy of narrow-band UVB in patients who had at least two treatments per week for 12 weeks. In this subgroup of patients, 60% achieved clear or almost clear skin and nearly 50% achieved the equivalent of a Psoriasis Area and Severity Index (PASI) 90 score.

“Home phototherapy is clearly non-inferior to office-based phototherapy across all skin types and both primary outcomes, PGA and DLQI, and both have excellent effectiveness and safety in real-world settings,” Dr. Gelfand concluded. “These data support the use of home phototherapy as a first-line treatment option for psoriasis, including those with no prior phototherapy experience.”

LITE Study Described as “Groundbreaking”

One of the session moderators, dermatologist Andrew Blauvelt, MD, MBA, of the Oregon Medical Research Center, Portland, asked about the impact that lockdowns during the early phase of the COVID-19 pandemic had on the trial. “The study shut down for a couple weeks during the initial lockdown, but we got back up and running pretty quickly,” Dr. Gelfand responded. “We didn’t study that specific period of time, but the study was going on well before COVID and well after COVID restrictions were lifted. We’ll have to analyze that period of time you question but I suspect that it’s not driving the results we see.”

Asked to comment, Henry W. Lim, MD, a dermatologist with Henry Ford Health in Detroit, characterized the findings of the study as “groundbreaking, because it looked at a real-life situation in the use of phototherapy at home vs in the office, showing that the home phototherapy is not inferior to office-based phototherapy.”

TOPLINE: 

The results of a recent study suggest that biologics and small molecule inhibitors (SMIs) do not impair the protective effect of COVID-19 vaccine against hospitalization in patients with psoriasis and hidradenitis suppurativa (HS).

METHODOLOGY:

• It remains unknown whether immunomodulatory therapies impair COVID-19 vaccine efficacy and increase hospitalization rates linked to COVID-19 in patients with inflammatory skin conditions such as psoriasis or HS.
• Researchers conducted a cross-sectional study using data from the Epic Cosmos database from January 2020 to October 2023, identifying 30,845 patients with psoriasis or HS.
• Overall, 22,293 patients with documented completion of their primary COVID-19 vaccine series were included in the analysis.
• Of the vaccinated patients, they compared 7046 patients with psoriasis on SMIs and 2033 with psoriasis or HS on biologics with 13,214 patients who did not receive biologics or SMIs.
• The primary outcome was the COVID-19 hospitalization rate.
• Treatment with biologics did not increase COVID-19-related hospitalization rates in vaccinated patients with psoriasis or HS (hospitalization rate, 6.0% for both those taking and those not taking a biologic; P > .99).
• Similarly, hospitalization rates did not significantly differ between vaccinated patients who received SMIs vs those who did not (7.1% vs 6.0%; P = .0596).

IN PRACTICE:

These findings “encourage dermatologists to continue treating [psoriasis]/HS confidently despite the ongoing COVID-19 pandemic,” the authors concluded.

SOURCE:

The study led by Bella R. Lee from Ohio State University Wexner Medical Center, Columbus, was published online on March 13, 2024, in the Journal of the American Academy of Dermatology. 

LIMITATIONS:

Multivariable adjustments could not be performed in this study due to unavailability of individual-level data, and hospital admissions that occurred outside the Epic system were not captured.

DISCLOSURES:

The study did not receive any funding. All authors declared no conflicts of interest.

SAN DIEGO — In published trials, both an interleukin (IL)–17 inhibitor and an IL-23 inhibitor achieved impressive rates of clear or almost clear responses in patients with moderate to severe plaque psoriasis, but late-breaker data presented at the annual meeting of the American Academy of Dermatology show that these types of responses are sustained for as long as patients have remained on therapy.

Of the two, the longer follow up is with the IL-17 inhibitor bimekizumab (Bimzelx). In a 4-year open-label extension study, the Psoriasis Area and Severity Index (PASI) 90 rate was approximately 85% in treated patients, according to Mark Lebwohl, MD, professor and chairman emeritus of the Department of Dermatology, Icahn School of Medicine at Mount Sinai in New York City

A PASI 90 score signifies that 90% of skin surface area is cleared. The proportion of patients who achieved a PASI 100 score, signifying total clearance, approached 70% at 4 years in the group with the greatest response. PASI 90 and PASI 100 rates at this point were only modestly lower than those reported at the end of the double-blind phase 3 trial when evaluated 3 years earlier. 

Follow-up with a novel oral anti-IL-23 inhibitor JNJ-2113 (JNJ-77242113) was only 52 weeks, far shorter. But again, the response for the most effective dose at the end of this period was essentially unchanged from that at 16 weeks. Among those on the highest and most effective test dose of once-daily 100 mg, the PASI 90 at 1 year was 64.3%, a rate that was essentially unchanged from week 16.

[embed:render:related:node:267966]

No Apparent Loss of Benefit Over Time

“We can really look at those dose-response curves and see that there is, overall, a maintenance of response,” reported Laura K. Ferris, MD, PhD, professor and director of clinical trials, Department of Dermatology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania. In her presentation of the data, she showed similar sustained control for the most effective doses of JNJ-2113 for multiple clinical outcomes, including an investigator’s global assessment (IGA) score of 0 or 1, also signifying clear or near clear skin.

Bimekizumab, a monoclonal antibody that inhibits both IL-17A and IL-17F, is already approved for the treatment of plaque psoriasis. The 52-week BE SURE trial, which provided the 478 patients who entered into the BE BRIGHT open label extension study, was published in The New England Journal of Medicine in July 2021. 

In the 4-year data reported by Dr. Lebwohl, three groups were compared: Those initially randomized to an every-4-week dosing schedule of bimekizumab over the course of the 52-week BE SURE trial; those randomized to an every-4-week bimekizumab schedule who were then subsequently switched to an every-8-week schedule; and those initiated on the TNF-inhibitor adalimumab (Humira) and were then switched at week 24 to every-4-week bimekizumab.

The PASI 90 responses at 52 weeks in these three groups, respectively, were 91.2%, 89.3%, and 95.2%. At 4 years, this almost clear response was observed in 82.4%, 83.2%, and 87.6%, respectively. At 52 weeks, the PASI 100 responses in these three groups, respectively, were 75.3%, 74.2%, and 72.9%. At 4 years, 61.9%, 58.5%, and 69.5% still had complete skin clearance.

Bimekizumab was well tolerated during the randomized trial, reported Dr. Lebwohl. The rates of nasopharyngitis and oral candidiasis, which were observed in approximately 12% and 8%, respectively, of treated patients during the randomized phase remained at about the same level in the long-term follow up. There were no new safety signals, he said.
 

JNJ-2113 Is First Potential Oral IL-23 Inhibitor

JNJ-2113 is a first-in-class oral peptide that binds to the IL-23 receptor, blocking the IL-23 signaling pathway. If approved, it would be the first oral therapy targeting IL-23. The 16-week outcomes of the dose-finding FRONTIER 1 phase 2b trial were published in The New England Journal of Medicine earlier this year. The primary endpoint was PASI 75, achieved by 79% of those on the 100 mg twice daily dose at week 16, vs 9% on placebo, and at 52 weeks, was 76%. 

“The proportion of patients achieving the FRONTIER 1 primary endpoint was maintained from week 16 to the end of week 52 in the extension study,” Dr. Ferris said, but further pointed out that rates of near or complete clearance achieved at week 16 were also essentially unchanged at week 52. This was true of PASI scores and IGA. 

Clearance of psoriatic lesions on the scalp was particularly impressive. By scalp-specific IGA, rates of clear or near clear (0/1) were not just maintained but improved over the course of follow-up, reaching 75.1% at 52 weeks in the highest dose group, she said.

JNJ-2113 was well tolerated in FRONTIER 1 and remained so during long-term follow-up, in the FRONTIER 2 extension study, according to Dr. Ferris. The most common complaints with JNJ-2113, such as nasopharyngitis (18.1% vs 25.7% in placebo), did not appear to differ significantly from placebo and the treatment remained well tolerated over the course of the extended follow-up.

There are limited direct comparisons of different biologics active in the treatment of plaque psoriasis for efficacy and safety, but these data appear to show a depth and durability of benefit for psoriasis that is exceptional, Dr. Lebwohl told this news organization. “The PASI 100 scores achieved by bimekizumab exceed anything we have seen to date,” he said. “And the durability of those exceedingly high scores is remarkable.”

Dr. Lebwohl reports financial relationships with approximately 40 pharmaceutical companies, including UCB Pharma, which developed bimekizumab. Dr. Ferris reports financial relationships with more than 20 pharmaceutical companies, including Janssen, which is developing JNJ-2113.

Hidradenitis suppurativa (HS)—a chronic, relapsing, inflammatory disorder involving terminal hair follicles in apocrine gland–rich skin—manifests as tender inflamed nodules that transform into abscesses, sinus tracts, and scarring.^1,2 The etiology of HS is multifactorial, encompassing lifestyle, microbiota, hormonal status, and genetic and environmental factors. These factors activate the immune system around the terminal hair follicles and lead to hyperkeratosis of the infundibulum of the hair follicles in intertriginous regions. This progresses to follicular occlusion, stasis, and eventual rupture. Bacterial multiplication within the plugged pilosebaceous units further boosts immune activation. Resident and migrated cells of the innate and adaptive immune system then release proinflammatory cytokines such as tumor necrosis factor, IL-1β, and IL-17, which further enhance immune cell influx and inflammation.^3,4 This aberrant immune response propagates the production of deep-seated inflammatory nodules and abscesses.^3-8

The estimated prevalence of HS is 1% worldwide.⁹ It is more prevalent in female and Black patients (0.30%) than White patients (0.09%) and is intermediate in prevalence in the biracial population (0.22%).¹⁰ Hidradenitis suppurativa is thought to be associated with lower socioeconomic status (SES). In a retrospective analysis of HS patients (N=375), approximately one-third of patients were Black, had advanced disease, and had a notably lower SES.¹¹ Furthermore, HS has been reported to be associated with systemic inflammation and comorbidities such as morbid obesity (38.3%) and hypertension (39.6%) as well as other metabolic syndrome–related disorders and depression (48.1%).¹

Hidradenitis suppurativa may contribute to the risk for depression through its substantial impact on health-related quality of life, which culminates in social withdrawal, unemployment, and suicidal thoughts.¹² The high prevalence of depression in individuals with HS¹ and its association with systemic inflammation¹³ increases the likelihood that a common genetic predisposition also may exist between both conditions. Because depression frequently has been discovered as a concomitant diagnosis in patients with HS, we hypothesize that a shared genetic susceptibility also may exist between the 2 disorders. Our study sought to explore data on the co-occurrence of depression with HS, including its demographics and racial data.

Methods

We conducted a PubMed search of articles indexed for MEDLINE as well as Google Scholar using the terms depression and hidradenitis suppurativa to obtain all research articles published from 2000 to 2022. Articles were selected based on relevance to the topic of exploration. English-language articles that directly addressed the epidemiology, etiology, pathophysiology, and co-occurrence of both depression and HS with numerical data were included. Articles were excluded if they did not explore the information of interest on these 2 disorders or did not contain clear statistical data of patients with the 2 concurrent medical conditions.

Results

Twenty-two cross-sectional, prospective, and retrospective studies that fit the search criteria were identified and included in the analysis (eTable).^1,14-34 Sixteen (72.7%) studies were cross-sectional, 5 (22.7%) were retrospective, and only 1 (4.5%) was a prospective study. Only 6 of the studies provided racial data,^{1,14,17,26,28,32} and of them, 4 had predominately White patients,^1,14,26,32 whereas the other 2 had predominantly Black patients.^17,28

CT113003137_eTable_part2.jpg

Hidradenitis suppurativa was found to coexist with depression in all the studies, with a prevalence of 1.2% to 48.1%. There also was a higher prevalence of depression in HS patients than in the control patients without HS. Furthermore, a recent study by Wright and colleagues¹⁴ stratified the depression prevalence data by age and found a higher prevalence of depression in adults vs children with HS (30% vs 12%).

Comment

Major depression—a chronic and debilitating illness—is the chief cause of disability globally and in the United States alone and has a global lifetime prevalence of 17%.³⁵ In a study of 388 patients diagnosed with depression and 404 community-matched controls who were observed for 10 years, depressed patients had a two-thirds higher likelihood of developing a serious physical illness than controls. The depression-associated elevated risk for serious physical illness persisted after controlling for confounding variables such as alcohol abuse, smoking, and level of physical activity.³⁶ Studies also have demonstrated that HS is more prevalent in Black individuals¹⁰ and in individuals of low SES,³⁷ who are mostly the Black and Hispanic populations that experience the highest burden of racial microaggression³⁸ and disparities in health access and outcomes.^39,40 The severity and chronicity of major depressive disorder also is higher in Black patients compared with White patients (57% vs 39%).⁴¹ Because major depression and HS are most common among Black patients who experience the highest-burden negative financial and health disparities, there may be a shared genetic disposition to both medical conditions.

Moreover, the common detrimental lifestyle choices associated with patients with depression and HS also suggest the possibility of a collective genetic susceptibility. Patients with depression also report increased consumption of alcohol, tobacco, and illicit substances; sedentary lifestyle leading to obesity; and poor compliance with prescribed medical treatment.⁴² Smoking and obesity are known contributors to the pathogenesis of HS, and their modification also is known to positively impact the disease course. In a retrospective single-cohort study, 50% of obese HS patients (n=35) reported a substantial decrease in disease severity after a reduction of more than 15% in body mass index over 2 years following bariatric surgery (n=35).⁴³ Patients with HS also have reported disease remission following extensive weight loss.⁴⁴ In addition, evidence has supported smoking cessation in improving the disease course of HS.⁴³ Because these detrimental lifestyle choices are prevalent in both patients with HS and those with depression, a co-genetic susceptibility also may exist.

Furthermore, depression is characterized by a persistent inflammatory state,^13,45 similar to HS.⁴⁶ Elevated levels of a variety of inflammatory markers, such as C-reactive protein (CRP), IL-6, and soluble intercellular adhesion molecule 1, have been reported in patients with depression compared with healthy controls.^13,45 Further analysis found a positive correlation and a strong association between depression and these inflammatory markers.⁴⁷ Moreover, adipokines regulate inflammatory responses, and adipokines play a role in the pathogenesis of HS. Adipokine levels such as elevated omentin-1 (a recently identified adipokine) were found to be altered in patients with HS compared with controls.⁴⁸ Results from clinical studies and meta-analyses of patients with depression also have demonstrated that adipokines are dysregulated in this population,^49,50 which may be another potential genetic link between depression and HS.

In addition, genetic susceptibility to depression and HS may be shared because the inflammatory markers that have a strong association with depression also have been found to play an important role in HS treatment and disease severity prediction. In a retrospective cohort study of 404 patients, CRP or IL-6 levels were found to be reliable predictors of HS disease severity, which may explain why anti–tumor necrosis factor antibody regimens such as adalimumab and infliximab have clinically ameliorated disease activity in several cases of HS.⁵¹ In a study evaluating these drugs, high baseline levels of high-sensitivity CRP and IL-6 were predictive of patient response to infliximab.⁵² In a meta-analysis evaluating 20,791 participants, an association was found between concurrent depression and CRP. Furthermore, inflammation measured by high levels of CRP or IL-6 was observed to predict future depression.⁵³ If the same inflammatory markers—CRP and IL-6—both play a major role in the disease activity of depression and HS, then a concurrent genetic predisposition may exist.

Conclusion

Understanding the comorbidities, etiologies, and risk factors for the development and progression of HS is an important step toward improved disease management. Available studies on comorbid depression in HS largely involve White patients, and more studies are needed in patients with skin of color, particularly the Black population, who have the highest prevalence of HS.¹⁰ Given the evidence for an association between depression and HS, we suggest a large-scale investigation of this patient population that includes a complete medical history, onset of HS in comparison to the onset of depression, and specific measures of disease progress and lifetime management of depression, which may help to increase knowledge about the role of depression in HS and encourage more research in this area. If shared genetic susceptibility is established, aggressive management of depression in patients at risk for HS may reduce disease incidence and severity as well as the psychological burden on patients.

Hidradenitis suppurativa (HS)—a chronic, relapsing, inflammatory disorder involving terminal hair follicles in apocrine gland–rich skin—manifests as tender inflamed nodules that transform into abscesses, sinus tracts, and scarring.^1,2 The etiology of HS is multifactorial, encompassing lifestyle, microbiota, hormonal status, and genetic and environmental factors. These factors activate the immune system around the terminal hair follicles and lead to hyperkeratosis of the infundibulum of the hair follicles in intertriginous regions. This progresses to follicular occlusion, stasis, and eventual rupture. Bacterial multiplication within the plugged pilosebaceous units further boosts immune activation. Resident and migrated cells of the innate and adaptive immune system then release proinflammatory cytokines such as tumor necrosis factor, IL-1β, and IL-17, which further enhance immune cell influx and inflammation.^3,4 This aberrant immune response propagates the production of deep-seated inflammatory nodules and abscesses.^3-8

The estimated prevalence of HS is 1% worldwide.⁹ It is more prevalent in female and Black patients (0.30%) than White patients (0.09%) and is intermediate in prevalence in the biracial population (0.22%).¹⁰ Hidradenitis suppurativa is thought to be associated with lower socioeconomic status (SES). In a retrospective analysis of HS patients (N=375), approximately one-third of patients were Black, had advanced disease, and had a notably lower SES.¹¹ Furthermore, HS has been reported to be associated with systemic inflammation and comorbidities such as morbid obesity (38.3%) and hypertension (39.6%) as well as other metabolic syndrome–related disorders and depression (48.1%).¹

Hidradenitis suppurativa may contribute to the risk for depression through its substantial impact on health-related quality of life, which culminates in social withdrawal, unemployment, and suicidal thoughts.¹² The high prevalence of depression in individuals with HS¹ and its association with systemic inflammation¹³ increases the likelihood that a common genetic predisposition also may exist between both conditions. Because depression frequently has been discovered as a concomitant diagnosis in patients with HS, we hypothesize that a shared genetic susceptibility also may exist between the 2 disorders. Our study sought to explore data on the co-occurrence of depression with HS, including its demographics and racial data.

Methods

We conducted a PubMed search of articles indexed for MEDLINE as well as Google Scholar using the terms depression and hidradenitis suppurativa to obtain all research articles published from 2000 to 2022. Articles were selected based on relevance to the topic of exploration. English-language articles that directly addressed the epidemiology, etiology, pathophysiology, and co-occurrence of both depression and HS with numerical data were included. Articles were excluded if they did not explore the information of interest on these 2 disorders or did not contain clear statistical data of patients with the 2 concurrent medical conditions.

Results

Twenty-two cross-sectional, prospective, and retrospective studies that fit the search criteria were identified and included in the analysis (eTable).^1,14-34 Sixteen (72.7%) studies were cross-sectional, 5 (22.7%) were retrospective, and only 1 (4.5%) was a prospective study. Only 6 of the studies provided racial data,^{1,14,17,26,28,32} and of them, 4 had predominately White patients,^1,14,26,32 whereas the other 2 had predominantly Black patients.^17,28

Hidradenitis suppurativa was found to coexist with depression in all the studies, with a prevalence of 1.2% to 48.1%. There also was a higher prevalence of depression in HS patients than in the control patients without HS. Furthermore, a recent study by Wright and colleagues¹⁴ stratified the depression prevalence data by age and found a higher prevalence of depression in adults vs children with HS (30% vs 12%).

Comment

Major depression—a chronic and debilitating illness—is the chief cause of disability globally and in the United States alone and has a global lifetime prevalence of 17%.³⁵ In a study of 388 patients diagnosed with depression and 404 community-matched controls who were observed for 10 years, depressed patients had a two-thirds higher likelihood of developing a serious physical illness than controls. The depression-associated elevated risk for serious physical illness persisted after controlling for confounding variables such as alcohol abuse, smoking, and level of physical activity.³⁶ Studies also have demonstrated that HS is more prevalent in Black individuals¹⁰ and in individuals of low SES,³⁷ who are mostly the Black and Hispanic populations that experience the highest burden of racial microaggression³⁸ and disparities in health access and outcomes.^39,40 The severity and chronicity of major depressive disorder also is higher in Black patients compared with White patients (57% vs 39%).⁴¹ Because major depression and HS are most common among Black patients who experience the highest-burden negative financial and health disparities, there may be a shared genetic disposition to both medical conditions.
