Spinosad: New kid on the block for treating scabies
HONOLULU – , Anthony J. Mancini, MD, said during a presentation at the Hawaii Dermatology Seminar provided by MedscapeLIVE!
In April 2021, spinosad topical suspension 0.9%, was approved by the Food and Drug Administration for treating scabies infestations in adult and pediatric patients 4 years of age and older – a first-in-class drug and the first new scabicide approved in 31 years. It was also approved for treating head lice in adults and children aged 6 months of age and older.
“Scabies has been described as the worst itch one can experience,” said Dr. Mancini, professor of pediatrics and dermatology at Northwestern University, Chicago. “It’s a hallmark of the disease, it can persist for weeks, it’s most intense at night, and patients report various sensations. It’s believed to be a both type I and type IV hypersensitivity reaction.”
The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs. Besides intense itching, the classic presentation consists of a skin rash composed of inflammatory papules, linear burrows and crusted papules (especially on the hands, feet, and groin), and at times, larger red nodules. “Scabies nodules can persist for many months,” he said.
The Global Burden of Disease Study 2015 cited scabies as having the greatest burden of disease in tropical regions, especially among children, adolescents, and the elderly. The greatest burden of disability-adjusted life years (DALYs) occurred in East and Southeast Asia, Oceana, and tropical South America, but in North America, there was a 24% increase in the DALY rate between 1990 and 2015.
In addition, the World Health Organization designated scabies as a neglected tropical disease in 2017 and included it in its 10-year road map for neglected tropical diseases 2021-2030 with goals of promoting disease awareness and encouraging research and achieving global control.
“In our country, we typically see scabies treated successfully without complications, but there can be complications, especially in underdeveloped areas, like Staph aureus and Group A beta-hemolytic streptococcal infections,” which can be fatal, said Dr. Mancini, who is also head of pediatric dermatology at Ann & Robert H. Lurie Children’s Hospital of Chicago.
Permethrin 5% cream is typically offered as first-line topical therapy in the United States for the treatment of scabies. However, in vitro studies and small investigator-initiated in vivo studies have reported that efficacy appears to be decreasing. In one of the trials, Italian researchers enrolled 155 patients who were treated with permethrin 5% for 8 hours for 2 consecutive days and repeated the treatment 5 days later . Following the course of permethrin, only 34 responded, 96 failed treatment, and 25 were lost to follow-up.
“The study authors concluded that mite resistance to permethrin 5% seems to be increasing, following a path like other ectoparasite resistance,” said Dr. Mancini, who was not involved with the study. “We may even be seeing more ivermectin resistance in some geographic locations, as well.”
According to new scabicide efficacy criteria established by the FDA in 2016, complete cure is now defined as meeting both clinical and confirmatory criteria. A clinical cure means that all signs and symptoms of scabies have completely resolved, including burrows, inflammatory/noninflammatory lesions, and pruritus. A confirmatory cure means there is an absence of mites, eggs, scybala (feces), and burrows via microscopy or dermoscopy.
Enter spinosad, which is derived from a naturally occurring soil microorganism known as Saccharopolyspora spinosa and is composed of two active molecules: spinosyn A and spinosyn D. According to Dr. Mancini, spinosad’s mechanism of action is unique from other medications used to treat ectoparasites. It activates nicotinic and GABA-gated sodium channels, leads to sodium influx in the insect nerves, hyperexcitation, then paralysis and death. Cross-resistance to other insecticides has not been reported, he added, and there is no known evidence of resistance to its active compound.
Approval of the drug was based on data from two phase 3 randomized clinical trials involving 551 index cases and household contacts. In the intent-to-treat population, with the two trials combined, complete cure was achieved in 78.1% of the spinosad-treated group, compared with 39.6% in the vehicle group (P < .0001), clinical cure was achieved in 79.6% of the spinosad group, compared with 41.2% in the vehicle group (P < .001), and microscopic cure occurred in 85.9% of the spinosad group, compared with 52.6% in the vehicle group (P < .001).
Of the 306 participants in the study, the only adverse events reported by more than one patient each included abdominal pain, back pain, cough, headache, neck pain, and decreased weight in two patients each (0.8%), which investigators believed were not attributable to the study drug. Adverse events that investigators considered to be potentially related to the study drug included burning sensation in two participants (0.7%) and dry skin in another (0.3%). In clinical trials reported in the prescribing information, adverse events occurring in greater than 1% of subjects included application-site irritation (3% spinosad vs. 0% vehicle) and dry skin (2% spinosad vs. 0% vehicle).
“Spinosad met the FDA’s new stringent criteria, with all signs and symptoms of scabies completely resolved and confirmed via microscopy or dermoscopy,” said Dr. Mancini, who was not involved in the trials. “The patented formulation drives the active compound to the stratum corneum, where mites live and breed. It’s a single full-body application, without any resistance observed to date. This is an exciting newer option for treating our scabies patients.”
In an interview at the meeting, John S. Barbieri, MD, MBA, of the department of dermatology, Brigham and Women’s Hospital, Boston, said that, while he has no clinical experience with spinosad for scabies, he welcomes a new option for the condition. “The fact that it has a different mechanism of action than permethrin is a good thing,” he said.
Dr. Mancini disclosed that he is a consultant or an adviser for ParaPRO, the manufacturer of spinosad, and Cassiopea, Castle Creek, Novan, Novartis, and Verrica. He was not involved in clinical trials of spinosad. Dr. Barbieri disclosed that he receives consulting fees from Dexcel.

AT THE MEDSCAPELIVE! HAWAII DERMATOLOGY SEMINAR
Nearly one in three patients with IBD affected by skin lesions
People with inflammatory bowel disease (IBD) commonly develop skin lesions linked to their condition, but until now few researchers looked at how common they are.
, according to the prospective, single-center study.
“Skin lesions in IBD patients are much more prevalent than it is generally accepted. The lesions may be related to the pathogenesis of IBD, but it is very important to know that the modern biological therapies may also cause skin lesions,” said senior study author Laimas Jonaitis, MD, PhD, professor in the department of gastroenterology at Lithuanian University of Health Sciences in Kaunas.
“If the gastroenterologist is experienced and has enough competence, he or she may establish the diagnosis, but in all other cases it is wise and advisable to refer the patient to the dermatologist,” Dr. Jonaitis said. A referral should include the history and full treatment for IBD.
The results were presented as a poster at the annual congress of the European Crohn’s and Colitis Organisation, held in Copenhagen and virtually.
Dr. Jonaitis and colleagues conducted a literature analysis to determine the prevalence of extra-abdominal manifestations of IBD. The lack of published data prompted them to survey 152 consecutive patients with IBD receiving outpatient treatment at their institution. The patients completed questionnaires from January to October 2022 about any cutaneous lesions.
The mean age of patients was 42 years, and 58% were men. A majority, 72%, had ulcerative colitis, and 28% had Crohn’s disease.
Prevalence of skin lesions
A total of 43% of participants reported skin lesions, but only 30% of patients had lesions considered related to IBD or IBD therapy due to their emergence after the patient’s IBD diagnosis.
By IBD diagnosis, 29% of patients with ulcerative colitis and 33% of patients with Crohn’s disease had lesions related to their condition. The difference in skin lesion prevalence between the two groups was not significant (P > .05), the researchers noted.
The team further investigated the types of skin lesions deemed to be associated with IBD or IBD therapy.
Overall, they found psoriasis in nine patients, eczema in nine, erythema nodosum in six, pyoderma gangrenosum in five, allergic rash in four, and vitiligo in two. They found acne, epidermolysis bullosa acquisita, and hemorrhagic vasculitis in one patient each.
Specifically, among patients with ulcerative colitis, skin lesions were reported in 8 of 27 with left-sided colitis, 2 of 15 with ulcerative colitis proctitis, and 22 of 67 patients with pancolitis. The difference between the groups of proctitis and pancolitis was significant (P = .03).
Within the group with Crohn’s disease, skin lesions were reported in 3 of 15 patients with ileitis, 4 of 10 with colitis, and 7 of 17 with ileocolitis. The difference among these groups was not significant (P > .05).
The most common skin lesions observed in Crohn’s disease were erythema nodosum and eczema, and in ulcerative colitis, psoriasis and eczema, the researchers reported.
They also noted that the cutaneous lesions were significantly more prevalent in extensive ulcerative colitis compared with distal disease.
Skin lesions add to patient misery
“Skin lesions are considered a burden to patients with IBD and add to their suffering,” said Sara Mesilhy, MBBS, a gastroenterologist with the Royal College of Physicians in the United Kingdom, who was not affiliated with the research.
The severity and location of the disease appears to play a role because researchers found extensive ulcerative colitis may carry a higher risk for the development of skin lesions, Dr. Mesilhy noted.
The first step when facing skin lesions is to control the disease activity via the best treatment option, Dr. Mesilhy suggested.
The study was independently supported. Dr. Jonaitis and Dr. Mesilhy have disclosed no relevant financial relationships.

FROM ECCO 2023
A 9-year-old male presents with multiple thick scaly plaques on scalp, ears, and trunk
Given the characteristic clinical presentation, the most likely diagnosis is psoriasis.
Psoriasis is a chronic immune-mediated disease that is characterized by well-demarcated thick scaly plaques on face, scalp, and intertriginous skin. Psoriasis is more common in adults than children, but the incidence of psoriasis in children has increased over time.1 Clinical presentation of psoriasis includes erythematous hyperkeratotic plaques, usually sharply demarcated. Pediatric patients may have multiple small papules and plaques less than 1 cm in size – “drop-size” – known as guttate lesions. Scalp and facial involvement are common in children. Chronic, inflamed plaques with coarse scale can involve ears, elbows, knees, and umbilicus, and nail changes can include pits, ridges, hyperkeratosis, and onycholysis or “oil spots.” While the diagnosis is clinical, biopsy can sometimes be useful to distinguish psoriasis from other papulosquamous conditions. Psoriasis in children is associated with obesity, higher rates of cardiovascular disease over a lifetime, as well as arthritis and mental health disorders.2
What’s the differential diagnosis?
The differential diagnosis for psoriasis can include papulosquamous diseases such as nummular eczema, pityriasis rosea, and pityriasis rubra pilaris. Tinea corporis may also be considered.
Nummular eczema, also known as “discoid eczema” is characterized by multiple pruritic, coin-shaped, eczematous lesions that may be actively oozing. The term “nummular” is derived from the Latin for “coin,” as lesions are distinct and annular. It is commonly associated with atopic dermatitis, and may be seen with contact dermatitis as well. Oozing, lichenification, hyperpigmentation and limited extent of skin coverage can help distinguish nummular dermatitis from psoriasis.
Pityriasis rosea is a common self-limited disease that is characterized by the appearance of acute, oval, papulosquamous patches on the trunk and proximal areas of the extremities. It usually begins with a characteristic “herald” patch, a single round or oval, sharply demarcated, pink lesion on the chest, neck, or back. Pityriasis rosea and guttate psoriasis may show similar clinical findings but the latter lacks a herald patch and is often preceded by streptococcal throat infection.
Pityriasis rubra pilaris is a rarer inflammatory disease characterized by follicular, hyperkeratotic papules, thick orange waxy palms (palmoplantar keratoderma), and erythroderma. It can also cause hair loss, nail changes, and itching. The rash shows areas with no involvement, “islands of sparing,” which is a signature characteristic of pityriasis rubra pilaris. Skin biopsies are an important diagnostic tool for pityriasis rubra pilaris. In the case of circumscribed pityriasis rubra pilaris, it may look similar to psoriasis, but it can be differentiated in that it is often accompanied by characteristic follicular papules and involvement of the palms, which are more waxy and orange in color.
When evaluating annular scaly patches, it is always important to consider tinea corporis. Tinea corporis will commonly have an annular border of scale with relative clearing in the center of lesions. In addition, when topical corticosteroids are used for prolonged periods, skin fungal infections can develop into “tinea incognito,” with paradoxical worsening since the immune response is suppressed and the fungal infection worsens.
Our patient had been previously treated with topical corticosteroids (medium to high strength) and topical calcineurin inhibitors without significant improvement. Other topical therapies for psoriasis include vitamin analogues, tazarotene, and newer therapies such as topical roflumilast (a phosphodiesterase-4 inhibitor approved for psoriasis in children over 12 years of age).3,4 In addition, as the indications for biological agents have been expanded, there are various options for treating psoriasis in children and adolescents when more active treatment is needed. Systemic therapies for more severe disease include traditional systemic immunosuppressives (for example, methotrexate, cyclosporine) and biologic agents. The four biologic agents currently approved for children are etanercept, ustekinumab, ixekizumab, and secukinumab. Our patient was treated with ustekinumab, which is an injectable biologic agent that blocks interleukin-12/23, with good response to date.

Given the characteristic clinical presentation, the most likely diagnosis is psoriasis.
Psoriasis is a chronic immune-mediated disease that is characterized by well-demarcated thick scaly plaques on face, scalp, and intertriginous skin. Psoriasis is more common in adults than children, but the incidence of psoriasis in children has increased over time.1 Clinical presentation of psoriasis includes erythematous hyperkeratotic plaques, usually sharply demarcated. Pediatric patients may have multiple small papules and plaques less than 1 cm in size – “drop-size” – known as guttate lesions. Scalp and facial involvement are common in children. Chronic, inflamed plaques with coarse scale can involve ears, elbows, knees, and umbilicus, and nail changes can include pits, ridges, hyperkeratosis, and onycholysis or “oil spots.” While the diagnosis is clinical, biopsy can sometimes be useful to distinguish psoriasis from other papulosquamous conditions. Psoriasis in children is associated with obesity, higher rates of cardiovascular disease over a lifetime, as well as arthritis and mental health disorders.2
What’s the differential diagnosis?
The differential diagnosis for psoriasis can include papulosquamous diseases such as nummular eczema, pityriasis rosea, and pityriasis rubra pilaris. Tinea corporis may also be considered.
Nummular eczema, also known as “discoid eczema” is characterized by multiple pruritic, coin-shaped, eczematous lesions that may be actively oozing. The term “nummular” is derived from the Latin for “coin,” as lesions are distinct and annular. It is commonly associated with atopic dermatitis, and may be seen with contact dermatitis as well. Oozing, lichenification, hyperpigmentation and limited extent of skin coverage can help distinguish nummular dermatitis from psoriasis.
Pityriasis rosea is a common self-limited disease that is characterized by the appearance of acute, oval, papulosquamous patches on the trunk and proximal areas of the extremities. It usually begins with a characteristic “herald” patch, a single round or oval, sharply demarcated, pink lesion on the chest, neck, or back. Pityriasis rosea and guttate psoriasis may show similar clinical findings but the latter lacks a herald patch and is often preceded by streptococcal throat infection.
Pityriasis rubra pilaris is a rarer inflammatory disease characterized by follicular, hyperkeratotic papules, thick orange waxy palms (palmoplantar keratoderma), and erythroderma. It can also cause hair loss, nail changes, and itching. The rash shows areas with no involvement, “islands of sparing,” which is a signature characteristic of pityriasis rubra pilaris. Skin biopsies are an important diagnostic tool for pityriasis rubra pilaris. In the case of circumscribed pityriasis rubra pilaris, it may look similar to psoriasis, but it can be differentiated in that it is often accompanied by characteristic follicular papules and involvement of the palms, which are more waxy and orange in color.
When evaluating annular scaly patches, it is always important to consider tinea corporis. Tinea corporis will commonly have an annular border of scale with relative clearing in the center of lesions. In addition, when topical corticosteroids are used for prolonged periods, skin fungal infections can develop into “tinea incognito,” with paradoxical worsening since the immune response is suppressed and the fungal infection worsens.

A 9-year-old male is seen in the clinic with a 1-year history of multiple thick scaly plaques on scalp, ears, and trunk. He has been treated with hydrocortisone 1% ointment with no change in the lesions. He had upper respiratory tract symptoms 3 weeks prior to the visit.
Examination reveals erythematous, well-demarcated plaques of the anterior scalp with thick overlying micaceous scale with some extension onto the forehead and temples. Additionally, erythematous scaly patches on the ear, axilla, and umbilicus were noted. There was no palmar or plantar involvement. He denied joint swelling, stiffness, or pain in the morning.

Two feet–one hand syndrome
This condition, also known as ringworm, is a fungal infection caused by a dermatophyte, and presents as a superficial annular or circular rash with a raised, scaly border.
Symptoms include dryness and itchiness, and the lesions may appear red-pink on lighter skin and gray-brown on darker skin types. Although these infections can arise in a variety of combinations, two feet–one hand syndrome occurs in about 60% of cases. Trichophyton rubrum is the most common agent.
Diagnosis is made by patient history, dermoscopic visualization, and staining of skin scraping with KOH or fungal culture. Dermatophytes prefer moist, warm environments, so this disease is prevalent in tropical conditions and associated with moist public areas such as locker rooms and showers. As a result, tinea pedis is also nicknamed “athlete’s foot” for its common presentation in athletes. The fungus spreads easily through contact and can survive on infected surfaces, so patients often self-inoculate by touching/scratching the affected area then touching another body part. Cautions that should be taken to avoid transmission include not sharing personal care products, washing the area and keeping it dry, and avoiding close, humid environments.
The syndrome is highly associated with onychomycosis, which can be more difficult to treat and often requires oral antifungals. Tinea manuum is commonly misdiagnosed as hand dermatitis or eczema and treated with topical steroids, which will exacerbate or flare the tinea.
Two feet–one hand syndrome can typically be treated with over-the-counter topical antifungal medications such as miconazole or clotrimazole. Topical ketoconazole may be prescribed, and oral terbinafine or itraconazole are used in more severe cases when a larger body surface area is affected or in immunocompromised patients.

Biologics show signs of delaying arthritis in psoriasis patients
Patients with psoriasis treated with interleukin-12/23 inhibitors or IL-23 inhibitors were less likely to develop inflammatory arthritis, compared with those treated with tumor necrosis factor (TNF) inhibitors, according to findings from a large retrospective study.
While previous retrospective cohort studies have found biologic therapies for psoriasis can reduce the risk of developing psoriatic arthritis when compared with other treatments such as phototherapy and oral nonbiologic disease-modifying antirheumatic drugs, this analysis is the first to compare classes of biologics, Shikha Singla, MD, of the Medical College of Wisconsin, Milwaukee, and colleagues wrote in The Lancet Rheumatology.
In the analysis, researchers used the TriNetX database, which contains deidentified data from electronic medical health records from health care organizations across the United States. The study included adults diagnosed with psoriasis who were newly prescribed a biologic approved by the Food and Drug Administration for the treatment of psoriasis. Biologics were defined by drug class: anti-TNF, anti-IL-17, anti-IL-23, and anti–IL-12/23. Any patient with a diagnosis of psoriatic arthritis or other inflammatory arthritis prior to receiving a biologic prescription or within 2 weeks of receiving the prescription were excluded.
The researchers identified 15,501 eligible patients diagnosed with psoriasis during Jan. 1, 2014, to June 1, 2022, with an average follow-up time of 2.4 years. The researchers chose to start the study period in 2014 because the first non–anti-TNF drug for psoriatic arthritis was approved by the FDA in 2013 – the anti–IL-12/23 drug ustekinumab. During the study period, 976 patients developed inflammatory arthritis and were diagnosed on average 528 days after their biologic prescription.
In a multivariable analysis, the researchers found that patients prescribed IL-23 inhibitors (guselkumab [Tremfya], risankizumab [Skyrizi], tildrakizumab [Ilumya]) were nearly 60% less likely (adjusted hazard ratio, 0.41; 95% confidence interval, 0.17–0.95) to develop inflammatory arthritis than were patients taking TNF inhibitors (infliximab [Remicade], adalimumab [Humira], etanercept [Enbrel], golimumab [Simponi], certolizumab pegol [Cimzia]). The risk of developing arthritis was 42% lower (aHR, 0.58; 95% CI, 0.43-0.76) with the IL-12/23 inhibitor ustekinumab (Stelara), but there was no difference in outcomes among patients taking with IL-17 inhibitors (secukinumab [Cosentyx], ixekizumab [Taltz], or brodalumab [Siliq]), compared with TNF inhibitors. For the IL-12/23 inhibitor ustekinumab, all sensitivity analyses did not change this association. For IL-23 inhibitors, the results persisted when excluding patients who developed arthritis within 3 or 6 months after first biologic prescription and when using a higher diagnostic threshold for incident arthritis.
“There is a lot of interest in understanding if treatment of psoriasis will prevent onset of psoriatic arthritis,” said Joel M. Gelfand, MD, MSCE, director of the Psoriasis and Phototherapy Treatment Center at the University of Pennsylvania, Philadelphia, who was asked to comment on the results.
“To date, the literature is inconclusive with some studies suggesting biologics reduce risk of PsA, whereas others suggest biologic use is associated with an increased risk of PsA,” he said. “The current study is unique in that it compares biologic classes to one another and suggests that IL-12/23 and IL-23 biologics are associated with a reduced risk of PsA compared to psoriasis patients treated with TNF inhibitors and no difference was found between TNF inhibitors and IL-17 inhibitors.”
While the study posed an interesting research question, “I wouldn’t use these results to actually change treatment patterns,” Alexis R. Ogdie-Beatty, MD, an associate professor of medicine at the University of Pennsylvania, Philadelphia, said in an interview. She coauthored a commentary on the analysis. Dr. Gelfand also emphasized that this bias may have influenced the results and that these findings “should not impact clinical practice at this time.”
Although the analyses were strong, Dr. Ogdie-Beatty noted, there are inherent biases in this type of observational data that cannot be overcome. For example, if a patient comes into a dermatologist’s office with psoriasis and also has joint pain, the dermatologist may suspect that a patient could also have psoriatic arthritis and would be more likely to choose a drug that will work well for both of these conditions.
“The drugs that are known to work best for psoriatic arthritis are the TNF inhibitors and the IL-17 inhibitors,” she said. So, while the analysis found these medications were associated with higher incidence of PsA, the dermatologist was possibly treating presumptive arthritis and the patient had yet to be referred to a rheumatologist to confirm the diagnosis.
The researchers noted that they attempted to mitigate these issues by requiring that patients have at least 1 year of follow-up before receiving biologic prescription “to capture only the patients with no previous codes for any type of arthritis,” as well as conducting six sensitivity analyses.
The authors, and Dr. Ogdie-Beatty and Dr. Gelfand agreed that more research is necessary to confirm these findings. A large randomized trial may be “prohibitively expensive,” the authors noted, but pooled analyses from previous clinical trials may help with this issue. “We identified 14 published randomized trials that did head-to-head comparisons of different biologic classes with regard to effect on psoriasis, and these trials collectively contained data on more than 13,000 patients. Pooled analyses of these data could confirm the findings of the present study and would be adequately powered.”
But that approach also has limitations, as psoriatic arthritis was not assessed an outcome in these studies, Dr. Ogdie-Beatty noted. Randomizing patients who are already at a higher risk of developing PsA to different biologics could be one approach to address these questions without needing such a large patient population.
The study was conducted without outside funding or industry involvement. Dr. Singla reported no relevant financial relationships with industry, but several coauthors reported financial relationships with pharmaceutical companies that market biologics for psoriasis and psoriatic arthritis. Dr. Ogdie-Beatty reported financial relationships with AbbVie, Amgen, Bristol-Myers Squibb, Celgene, CorEvitas, Gilead, Happify Health, Janssen, Lilly, Novartis, Pfizer, and UCB. Dr. Gelfand reported financial relationships with Abbvie, Amgen, BMS, Boehringer Ingelheim, FIDE, Lilly, Leo, Janssen Biologics, Novartis, Pfizer, and UCB.

While previous retrospective cohort studies have found biologic therapies for psoriasis can reduce the risk of developing psoriatic arthritis when compared with other treatments such as phototherapy and oral nonbiologic disease-modifying antirheumatic drugs, this analysis is the first to compare classes of biologics, Shikha Singla, MD, of the Medical College of Wisconsin, Milwaukee, and colleagues wrote in The Lancet Rheumatology.
In the analysis, researchers used the TriNetX database, which contains deidentified data from electronic medical health records from health care organizations across the United States. The study included adults diagnosed with psoriasis who were newly prescribed a biologic approved by the Food and Drug Administration for the treatment of psoriasis. Biologics were defined by drug class: anti-TNF, anti-IL-17, anti-IL-23, and anti–IL-12/23. Any patient with a diagnosis of psoriatic arthritis or other inflammatory arthritis prior to receiving a biologic prescription or within 2 weeks of receiving the prescription were excluded.
The researchers identified 15,501 eligible patients diagnosed with psoriasis during Jan. 1, 2014, to June 1, 2022, with an average follow-up time of 2.4 years. The researchers chose to start the study period in 2014 because the first non–anti-TNF drug for psoriatic arthritis was approved by the FDA in 2013 – the anti–IL-12/23 drug ustekinumab. During the study period, 976 patients developed inflammatory arthritis and were diagnosed on average 528 days after their biologic prescription.
In a multivariable analysis, the researchers found that patients prescribed IL-23 inhibitors (guselkumab [Tremfya], risankizumab [Skyrizi], tildrakizumab [Ilumya]) were nearly 60% less likely (adjusted hazard ratio, 0.41; 95% confidence interval, 0.17–0.95) to develop inflammatory arthritis than were patients taking TNF inhibitors (infliximab [Remicade], adalimumab [Humira], etanercept [Enbrel], golimumab [Simponi], certolizumab pegol [Cimzia]). The risk of developing arthritis was 42% lower (aHR, 0.58; 95% CI, 0.43-0.76) with the IL-12/23 inhibitor ustekinumab (Stelara), but there was no difference in outcomes among patients taking with IL-17 inhibitors (secukinumab [Cosentyx], ixekizumab [Taltz], or brodalumab [Siliq]), compared with TNF inhibitors. For the IL-12/23 inhibitor ustekinumab, all sensitivity analyses did not change this association. For IL-23 inhibitors, the results persisted when excluding patients who developed arthritis within 3 or 6 months after first biologic prescription and when using a higher diagnostic threshold for incident arthritis.
“There is a lot of interest in understanding if treatment of psoriasis will prevent onset of psoriatic arthritis,” said Joel M. Gelfand, MD, MSCE, director of the Psoriasis and Phototherapy Treatment Center at the University of Pennsylvania, Philadelphia, who was asked to comment on the results.
“To date, the literature is inconclusive with some studies suggesting biologics reduce risk of PsA, whereas others suggest biologic use is associated with an increased risk of PsA,” he said. “The current study is unique in that it compares biologic classes to one another and suggests that IL-12/23 and IL-23 biologics are associated with a reduced risk of PsA compared to psoriasis patients treated with TNF inhibitors and no difference was found between TNF inhibitors and IL-17 inhibitors.”
While the study posed an interesting research question, “I wouldn’t use these results to actually change treatment patterns,” Alexis R. Ogdie-Beatty, MD, an associate professor of medicine at the University of Pennsylvania, Philadelphia, said in an interview. She coauthored a commentary on the analysis. Dr. Gelfand also emphasized that this bias may have influenced the results and that these findings “should not impact clinical practice at this time.”
Although the analyses were strong, Dr. Ogdie-Beatty noted, there are inherent biases in this type of observational data that cannot be overcome. For example, if a patient comes into a dermatologist’s office with psoriasis and also has joint pain, the dermatologist may suspect that a patient could also have psoriatic arthritis and would be more likely to choose a drug that will work well for both of these conditions.
“The drugs that are known to work best for psoriatic arthritis are the TNF inhibitors and the IL-17 inhibitors,” she said. So, while the analysis found these medications were associated with higher incidence of PsA, the dermatologist was possibly treating presumptive arthritis and the patient had yet to be referred to a rheumatologist to confirm the diagnosis.
The researchers noted that they attempted to mitigate these issues by requiring that patients have at least 1 year of follow-up before receiving biologic prescription “to capture only the patients with no previous codes for any type of arthritis,” as well as conducting six sensitivity analyses.
The authors, and Dr. Ogdie-Beatty and Dr. Gelfand agreed that more research is necessary to confirm these findings. A large randomized trial may be “prohibitively expensive,” the authors noted, but pooled analyses from previous clinical trials may help with this issue. “We identified 14 published randomized trials that did head-to-head comparisons of different biologic classes with regard to effect on psoriasis, and these trials collectively contained data on more than 13,000 patients. Pooled analyses of these data could confirm the findings of the present study and would be adequately powered.”
But that approach also has limitations, as psoriatic arthritis was not assessed an outcome in these studies, Dr. Ogdie-Beatty noted. Randomizing patients who are already at a higher risk of developing PsA to different biologics could be one approach to address these questions without needing such a large patient population.
The study was conducted without outside funding or industry involvement. Dr. Singla reported no relevant financial relationships with industry, but several coauthors reported financial relationships with pharmaceutical companies that market biologics for psoriasis and psoriatic arthritis. Dr. Ogdie-Beatty reported financial relationships with AbbVie, Amgen, Bristol-Myers Squibb, Celgene, CorEvitas, Gilead, Happify Health, Janssen, Lilly, Novartis, Pfizer, and UCB. Dr. Gelfand reported financial relationships with Abbvie, Amgen, BMS, Boehringer Ingelheim, FIDE, Lilly, Leo, Janssen Biologics, Novartis, Pfizer, and UCB. Dr. Gelfand is a deputy editor for the Journal of Investigative Dermatology.

FDA to review dupilumab for treating chronic spontaneous urticaria
The that is inadequately controlled by current standard of care.
CSU is an inflammatory skin condition that causes sudden hives and angioedema, most often on the face, hands, and feet. However, the throat and upper airways also can be affected. CSU is generally treated with H1 antihistamines, but this strategy is insufficient for approximately 50% of patients, according to a press release from the manufacturer, Regeneron, announcing the FDA acceptance of the application on March 7.
Dupilumab (Dupixent), first approved in 2017 for treating atopic dermatitis in adults, is a fully human monoclonal antibody that inhibits the signaling of the interleukin (IL)-4 and IL-13 pathways.
The application for FDA approval for CSU is based on data from a pair of phase 3 trials in two different populations, LIBERTY-CUPID A and B.
The first study (LIBERTY-CUPID A) randomized 138 CSU patients aged 6 years and older who were uncontrolled on antihistamines to additional treatment with dupilumab or placebo over 24 weeks. The dupilumab-treated patients showed a 63% reduction in itch severity compared with a 35% reduction in patients who received the placebo, measured by changes in a 0-21 itch severity scale, according to data presented at the 2022 American Academy of Allergy, Asthma and Immunology (AAAAI) meeting.
Patients in the dupilumab group also showed a 65% reduction in the severity of urticaria activity (itch and hives) compared with 37% of those on placebo. Overall rates of adverse events were similar between groups; the most common were injection site reactions, according to the company.
The second study (LIBERTY-CUPID B) assessed efficacy and safety of dupilumab in 108 patients with CSU aged 12-80 years who were symptomatic despite standard-of-care treatment and were intolerant or incomplete responders to the anti-IgE antibody omalizumab (Xolair), approved for CSU. Last year, the company announced that this study had been halted after an interim analysis found that while there were positive numerical trends in reducing itch and hives, they “did not meet statistical significance.” In the March 7 press release, the company said that results from this study provide “additional supporting data” for the approval application.
The target date for the FDA’s decision is Oct. 22, 2023, according to Regeneron. Regeneron and Sanofi also are investigating dupilumab for treating chronic inducible urticaria triggered by cold in a phase 3 study.

FDA accepts application for topical molluscum treatment
If approved, berdazimer gel would be the first FDA-approved prescription product for molluscum contagiosum in the United States, according to the company, Novan. The active ingredient in berdazimer gel 10.3% is berdazimer sodium, a novel nitric oxide–releasing agent.
Molluscum contagiosum is a benign but contagious skin infection characterized by red papules on the face, trunk, limbs, and axillae that may persist for years if left untreated.
The treatment was evaluated in the B-SIMPLE4 study, a phase 3 clinical trial including 891 individuals with molluscum contagiosum aged 6 months and older, with 3-70 raised lesions The mean age of the patients was approximately 7 years (range, 0.9-47.5 years) and 85.5% were White (4.7% were Black, 21.2% were Hispanic, and 1.4% were Asian). Study participants were randomized to berdazimer gel 10.3% or a vehicle gel applied as a thin layer to all lesions once daily for 12 weeks.
The full results of the B-SIMPLE4 study were published in JAMA Dermatology in July 2022. After 12 weeks of treatment, 32.4% of patients in the berdazimer group met the primary outcome of complete clearance of all lesions, versus 19.7% of those on the vehicle (P < .001). The rates of adverse events were similar and low in both groups. The most common adverse events in both groups were application-site pain and erythema, and most cases were mild or moderate. A total of 4.1% of berdazimer patients and 0.7% of placebo patients experienced adverse events that prompted treatment discontinuation.
The Prescription Drug User Fee goal date for the approval of berdazimer 10.3% for molluscum contagiosum is set for Jan. 5, 2024, according to Novan.

Pembrolizumab before and after melanoma surgery boosts outcomes
, show results from the phase 2 SWOG S1801 trial.
The trial involved 319 patients with operable stage IIIB to stage IV melanoma. The investigators found that patients who received pembrolizumab both before and after surgery (i.e., neoadjuvant and adjuvant therapy) fared better than those who received the drug only after surgery: The 2-year event-free survival rates were 72% vs. 49%, respectively.
The research was published in the New England Journal of Medicine, but similar results had already been presented at the European Society for Medical Oncology 2022 annual Meeting.
“It’s not just what you give; it’s when you give it,” said lead author Sapna Patel, MD, in a press release issued by the University of Texas MD Anderson Cancer Center, echoing comments she gave at ESMO 2022.
The study, she continued, “demonstrates the same treatment for resectable melanoma given before surgery can generate better outcomes.”
On the basis of their findings, Dr. Patel, who is associate professor of melanoma medical oncology at the University of Texas MD Anderson Cancer Center, Houston, said that patients with high-risk melanoma “should start immunotherapy prior to surgery to generate an immune response while the bulk of the melanoma and the anti-tumor T cells are intact.”
The mechanism of action of PD-1 blockade “relies on the presence of preexisting anti-tumor T cells attempting to attack cancer cells,” with the immunotherapy allowing the anti-tumor cells to proliferate and mediate clinical responses.
Resection of the bulk of the tumor is therefore “likely to take away some or even most of the potential anti-tumor T cells that would proliferate after PD-1 blockade,” they write.
Likely to apply also to nivolumab
Approached for comment, Jeffrey S. Weber, MD, PhD, professor of medicine, NYU Langone Medical Center, New York, said that outside of trials, both pembrolizumab and ipilimumab (Yervoy)/nivolumab (Opdivo) are already being used neoadjuvantly.
He thinks that the findings for neoadjuvant and adjuvant pembrolizumab could also apply to nivolumab because “the drugs are quite similar in efficacy.”
Dr. Weber told this news organization that, “even though the S1801 trial was not accepted as a registration trial by the FDA, I think that its results could very well change practice and confirm it for others who already use neoadjuvant therapy for palpable stage III melanoma.”
One question that is being addressed to an extent in the NADINA trial is whether adjuvant immunotherapy can be avoided all together and patients receive only neoadjuvant therapy, although Dr. Weber said, “I doubt that will be the case.”
Study details
In this study, patients were randomly assigned to either surgery followed by 18 doses of adjuvant pembrolizumab, or to receive 3 doses of neoadjuvant pembrolizumab followed by surgery and then 15 additional doses of adjuvant pembrolizumab.
After a median duration of follow-up of 14.7 months, there were 38 events in the neoadjuvant-adjuvant group and 67 in the adjuvant-only group.
“Events” were defined as disease progression, toxic effects, or complications that precluded surgery or the initiation of adjuvant therapy within 84 days of surgery, as well as the inability to fully resect the gross disease, melanoma recurrence, and death.
The team calculated that event-free survival was significantly longer in the neoadjuvant-adjuvant group (P = .004), with 2-year event-free survival at 72% vs. 49% in the adjuvant-only group.
“The benefit of neoadjuvant pembrolizumab was seen across all subgroups of patients,” the investigators note.
At the data cut-off, there were 14 deaths in the neoadjuvant-adjuvant group vs. 22 in the adjuvant-only group, which the researchers say is too few to allow “definitive comparison” in terms of overall survival.
Definitive surgery had been performed in 88% of neoadjuvant-adjuvant patients and in 95% of those assigned to adjuvant-only pembrolizumab. The most common reason for not undergoing surgery was disease progression.
Among the patients for whom safety data were available, 7% in the neoadjuvant-adjuvant group had at least one grade 3 or 4 adverse event related to pembrolizumab, whereas 7% had at least one grade 3 or 4 adverse event related to surgery.
In the adjuvant-only arm, 4% of patients had at least one grade 3 adverse event related to surgery, with no grade 4 adverse events reported.
The rates of grade 3 or 4 adverse events during adjuvant therapy were similar in the two groups, at 12% in patients assigned to neoadjuvant-adjuvant therapy and 14% in those given adjuvant-only pembrolizumab.
“Future studies can explore deescalation strategies for both surgery and adjuvant therapy, as well as approaches for patients whose melanoma does not respond to neoadjuvant therapy,” the researchers commented.
The study was funded by the National Cancer Institute and Merck Sharp and Dohme.
Dr. Patel reports numerous relationships with industry, including with Merck, manufacturer of pembrolizumab; other coauthors also have numerous relationships with industry. Dr. Weber is a regular columnist for this news organization and lists his disclosures in his Weber on Oncology column.

In the adjuvant-only arm, 4% of patients had at least one grade 3 adverse event related to surgery, with no grade 4 adverse events reported.
The rates of grade 3 or 4 adverse events during adjuvant therapy were similar in the two groups, at 12% in patients assigned to neoadjuvant-adjuvant therapy and 14% in those given adjuvant-only pembrolizumab.
“Future studies can explore deescalation strategies for both surgery and adjuvant therapy, as well as approaches for patients whose melanoma does not respond to neoadjuvant therapy,” the researchers commented.
The study was funded by the National Cancer Institute and Merck Sharp and Dohme.
Dr. Patel reports numerous relationships with industry, including with Merck, manufacturer of pembrolizumab; other coauthors also have numerous relationships with industry. Dr. Weber is a regular columnist for this news organization and lists his disclosures in his Weber on Oncology column.

Be vigilant about suspected cases of measles, expert advises
HONOLULU – .
“Measles is one of the most contagious of human viruses, and we are seeing a resurgence,” Adelaide A. Hebert, MD, professor of dermatology and pediatrics, and chief of pediatric dermatology at the Universtiy of Texas, Houston, said at the Hawaii Dermatology Seminar provided by MedscapeLIVE! “This is a re-emerging viral infection that dermatologists must recognize. Measles often starts behind the ears, and the eruption can look a lot like a drug eruption,” she noted. “Many of my pediatric colleagues have never seen a case of measles before because we have had a vaccine since 1963. Measles can almost entirely be prevented with vaccination. You get herd immunity if both doses have been administered to 95% of the population.”
In 2021, the World Health Organization estimated that 25 million children worldwide missed the measles vaccine. This caused 9 million cases of measles and 128,000 deaths in 22 countries, mainly from viral pneumonia, secondary bacterial pneumonia, and postviral encephalitis. According to the Centers for Disease Control and Prevention, 1,274 measles cases occurred in 31 states in 2019, mostly in individuals who were not vaccinated against it. Reported cases fell to 13 in 2020 but rose to 49 cases in 2021 and to 121 cases in 2022. As of Feb. 28, 2023, three cases have been reported in the United States.
“Measles spreads through direct contact with an infected person and through airborne transmission,” said Dr. Hebert, who recommended an article published in The Lancet for background on the topic. “Unlike COVID-19, measles has not mutated, so the original measles vaccine will work very well.”
Common clinical signs of measles include a generalized, maculopapular eruption lasting for 3 days or more, a temperature above 101° F plus cough, coryza, or conjunctivitis. Confirmation of measles can be made by PCR for viral RNA. Clinicians can also send a blood draw to the state public health lab for analysis. The serologic standard is a fourfold rise or fall in IgG titer with a paired sample sent 10-14 days after the initial collection.
“You can administer immune globulin up to 6 days after exposure to potentially prevent measles or decrease severity [in] immunocompromised hosts not previously vaccinated,” she said. The recommended intramuscular dose is 0.5 mL/kg, up to a dose of 15 mL/kg. Treatment is supportive and focused on relieving common symptoms and providing nutritional support. Administration of vitamin A is currently recommended for all children with acute measles.
Vitamin A supplements are available either as capsules (50,000 IU; 100,000 IU; 200,000 IU) or in liquid form. Parenteral formulations are also available. “Capsules need to be cut open and the contents squeezed into the mouths of children younger than 2 years,” Dr. Hebert said. “Capsules have the advantage that they can be given to mothers for administration at home.”
The recommended dosage of vitamin A in children is as follows, she said:
- Aged 12 months or older: 200,000 IU daily for 2 days.
- Aged 6 to 11 months: 100,000 IU daily for 2 days.
- Aged 6 months or younger: 50,000 IU daily for 2 days.
The American Academy of Pediatrics recommends a third dose given 2-4 weeks later to children with clinical signs and symptoms of vitamin A deficiency.
In an interview following the meeting, Moise L. Levy, MD, professor of internal medicine and pediatrics at the University of Texas, Austin, emphasized that when clinicians evaluate pediatric patients with viral symptoms such as fever, cough, and skin eruption, “measles should be in the differential diagnosis.” The 2022 uptick in measles cases “would be another reason to engage in regular vaccinations.”
Dr. Hebert disclosed that she is a consultant or advisor for AbbVie, Almirall, Amryt Pharma, Arcutis Biotherapeutics, Beiersdorf, Dermavant Sciences, Galderma Laboratories, L’Oreal, Novan, Ortho Dermatologics, Pfizer, and Verrica.
Dr. Levy disclosed that he is consultant or advisor for Abeona, Castle Creek, Dusa Pharma, Krystal Bio, Novan, Regeneron, and Sanofi-Genzyme.

AT THE MEDSCAPELIVE! HAWAII DERMATOLOGY SEMINAR
Widespread flaky red skin
This patient had erythroderma, which involves widespread erythema and scaling of the majority of the skin. Erythroderma can be caused by severe variants of several skin disorders, including atopic dermatitis, contact dermatitis, and psoriasis. In this case, a punch biopsy from the forearm was most consistent with erythrodermic psoriasis.
Erythrodermic psoriasis is a rare subtype of psoriasis and most often develops as an exacerbation of preexisting plaque psoriasis and is defined by erythema, scale, and desquamation covering 75% to 90% of the body surface.1 The alteration in the skin negatively affects heat exchange and hemodynamics and can be life threatening. Many cases develop as a rebound reaction in patients with preexisting psoriasis treated with systemic steroids that are discontinued. Patients with dehydration, poor urinary output, hypotension, or significant weakness may benefit from supportive inpatient care while treatment is initiated.1
Initial treatment options for patients with erythrodermic psoriasis include biologics and steroid-sparing immunosuppressants, such as cyclosporine and acitretin. While a patient awaits the initiation of a definitive therapy, topical triamcinolone 0.1% may be applied over the entire skin surface twice daily and covered with 2 layers of scrubs or pajamas. The pair closest to the skin should be slightly damp and the outer pair should be dry to help retain heat. These are referred to as wet wraps or wet pajama wraps.
The patient described here was hemodynamically stable and was allowed to initiate wet pajama wrap therapy at home while awaiting initiation of adalimumab as an outpatient. He has improved dramatically with adalimumab given subcutaneously every 2 weeks.
