Can skin bleaching lead to cancer?
SINGAPORE –
This question was posed by Ousmane Faye, MD, PhD, director general of Mali’s Bamako Dermatology Hospital, at the World Congress of Dermatology.
Dr. Faye explored the issue during a hot topics session at the meeting, prefacing that it was an important question to ask because “in West Africa, skin bleaching is very common.”
“There are many local names” for skin bleaching, he said. “For example, in Senegal, it’s called xessal; in Mali and Ivory Coast, its name is caco; in South Africa, there are many names, like ukutsheyisa.”
Skin bleaching refers to the cosmetic misuse of topical agents to change one’s natural skin color. It’s a centuries-old practice that people, mainly women, adopt “to increase attractiveness and self-esteem,” explained Dr. Faye.
To demonstrate how pervasive skin bleaching is on the continent, he presented a slide that summarized figures from six studies spanning the past 2 decades. Prevalence ranged from 25% in Mali (based on a 1993 survey of 210 women) to a high of 79.25% in Benin (from a sample size of 511 women in 2019). In other studies of women in Burkina Faso and Togo, the figures were 44.3% and 58.9%, respectively. The most recently conducted study, which involved 2,689 Senegalese women and was published in 2022, found that nearly 6 in 10 (59.2%) respondents used skin-lightening products.
But skin bleaching isn’t just limited to Africa, said session moderator Omar Lupi, MD, PhD, associate professor of dermatology at the Federal University of the State of Rio de Janeiro, when approached for an independent comment. “It’s a traditional practice around the world. Maybe not in the developed countries, but it’s quite common in Africa, in South America, and in Asia.”
His sentiments are echoed in a meta-analysis that was published in the International Journal of Dermatology in 2019. The work examined 68 studies involving more than 67,000 people across Africa, Asia, Europe, the Middle East, and North America. It found that the pooled lifetime prevalence of skin bleaching was 27.7% (95% confidence interval, 19.6-37.5; P < .01).
“This is an important and interesting topic because our world is shrinking,” Dr. Lupi told this news organization. “Even in countries that don’t have bleaching as a common situation, we now have patients who are migrating from one part [of the world] to another, so bleaching is something that can knock on your door and you need to be prepared.”
Misuse leads to complications
The issue is pertinent to dermatologists because skin bleaching is associated with a wide range of complications. Take, for example, topical steroids, which are the most common products used for bleaching, said Dr. Faye in his talk.
“Clobetasol can suppress the hypothalamic-pituitary-adrenal (HPA) function,” he said, referring to the body’s main stress response system. “It can also foster skin infection, including bacterial, fungal, viral, and parasitic infection.”
In addition, topical steroids that are misused as skin lighteners have been reported to cause stretch marks, skin atrophy, inflammatory acne, and even metabolic disorders such as diabetes and hypertension, said Dr. Faye.
To further his point, he cited a 2021 prospective case-control study conducted across five sub-Saharan countries, which found that the use of “voluntary cosmetic depigmentation” significantly increased a person’s risk for necrotizing fasciitis of the lower limbs (odds ratio, 2.29; 95% CI, 1.19-3.73; P = .0226).
Similarly, mercury, another substance found in products commonly used to bleach skin, has been associated with problems ranging from rashes to renal toxicity. And because it’s so incredibly harmful, mercury is also known to cause neurologic abnormalities.
Apart from causing certain conditions, prolonged use of skin-lightening products can change the way existing diseases present themselves as well as their severity, added Dr. Faye.
An increased risk
But what about skin bleaching’s link with cancer? “Skin cancer on Black skin is uncommon, yet it occurs in skin-bleaching women,” said Dr. Faye.
“Since 2000, we have had some cases of skin cancer associated with skin bleaching,” he continued, adding that squamous cell carcinoma (SCC) is the most frequent type of cancer observed.
If you look at what’s been published on the topic so far, you’ll see that “all the cases of skin cancer are located over the neck or some exposed area when skin bleaching products are used for more than 10 years,” said Dr. Faye. “And most of the time, the age of the patient ranges from 30 to 60 years.”
The first known case in Africa was reported in a 58-year-old woman from Ghana, who had been using skin bleaching products for close to 30 years. The patient presented with tumors on her face, neck, and arms.
Dr. Faye then proceeded to share more than 10 such carcinoma cases. “These previous reports strongly suggest a relationship between skin bleaching and skin cancers,” said Dr. Faye.
Indeed, there have been reports and publications in the literature that support his observation, including one last year, which found that use of the tyrosinase inhibitor hydroquinone was associated with approximately a threefold increased risk for skin cancer.
For some, including Brazil’s Dr. Lupi, Dr. Faye’s talk was enlightening: “I didn’t know about this relationship [of bleaching] with skin cancer, it was something new for me.”
But the prevalence of SCC is very low, compared with that of skin bleaching, Dr. Faye acknowledged. Moreover, the cancer observed in the cases reported could have resulted from a number of reasons, including exposure to harmful ultraviolet rays from the sun and genetic predisposition in addition to the use of bleaching products such as hydroquinone. “Other causes of skin cancer are not excluded,” he said.
To further explore the link between skin bleaching and cancer, “we need case-control studies to provide more evidence,” he added. Until then, dermatologists “should keep on promoting messages” to prevent SCC from occurring. This includes encouraging the use of proper sun protection in addition to discouraging the practice of skin bleaching, which still persists despite more than 10 African nations banning the use of toxic skin-lightening products.
Dr. Faye and Dr. Lupi report no relevant financial relationships.

Oral IL-23 receptor antagonist for psoriasis promising: Phase 2b study
SINGAPORE – across all doses, compared with placebo, according to results of the FRONTIER 1 trial.
In the 16-week phase 2b study, 255 adults with moderate to severe plaque psoriasis were randomly assigned into six treatment groups: placebo (n = 43), JNJ-2113 25 mg daily (n = 43), 25 mg twice daily (n = 41), 50 mg daily (n = 43), 100 mg daily (n = 43), or 100 mg twice daily (n = 42).
Of those who took the placebo, only 9.3% achieved the study’s primary endpoint of a 75% or greater improvement in the Psoriasis Area and Severity Index (PASI-75) by week 16. This was compared with 78.6% in the group that took the highest dose.
“Additionally, the onset of action was fairly fast: at week 4, more than 20% of patients had achieved PASI 75,” said Robert Bissonnette, MD, CEO of Innovaderm Research in Montreal, who presented the findings during a late-breaker session at the World Congress of Dermatology.
Patients in the remaining groups demonstrated a response that corresponded to dosing level: with 37.2%, 51.2%, 58.1%, and 65.1% achieving PASI-75 in the 25 mg daily, 25 mg twice-daily, 50 mg daily, and 100 mg daily groups, respectively.
“These results are very interesting because in terms of psoriasis treatment, if this is confirmed in phase 3, it would give us an oral alternative that would be selective for IL-23,” said Dr. Bissonnette, referring to the signaling pathway that plays a critical role in the pathogenesis of several immune-mediated inflammatory diseases, including plaque psoriasis.
Although rarely life-threatening, the skin disorder is often intractable to treatment. In recent years, therapies that block IL-23 signaling and downstream inflammatory cytokine production have proven useful. “We have on the market a number of biological agents targeting IL-23 that we use on a regular basis,” said Dr. Bissonnette. “However, there are currently no orally delivered therapies.”
If successful, JNJ-2113 – a first-in-class oral IL-23 antagonist peptide developed by Janssen – could change the treatment paradigm for patients with moderate to severe plaque psoriasis. “When I was first introduced to the concept, I thought it wouldn’t work as it’s a peptide, that it would be digested by the stomach,” he told the audience. “But because of its GI stability and its potency, when you administer it orally, you can detect pharmacological activity.”
A well-tolerated alternative
Participants in the FRONTIER 1 trial were on average about 44 years old and weighed 88.9 kg (195 lb). Most had been living with psoriasis for about 18 years, with a total PASI score of 19.05. In addition, 43.1% had been treated with phototherapy in the past, 22% with biologics, and 78.4% with systemics.
PASI 90 and 100 were among some of the secondary outcomes measured. Similar to the primary outcome of PASI 75, all treatment groups demonstrated a statistically significant dose-response in PASI 90, compared with placebo. For those on the highest dose of JNJ-2113, 59.5% and 40.5% achieved PASI 90 and PASI 100, respectively, by week 16. The corresponding figures for those receiving placebo were 2.3% and 0%.
The safety profile for JNJ-2113 across all doses was similar to that of placebo, with no evidence of a dose-dependent increase in the occurrence of adverse events (AEs). The most frequently reported AEs were COVID-19 and nasopharyngitis. There were three serious AEs (COVID-19, infected cyst, suicide attempt) among those on the active drug, but the investigators assessed that they were not related to the study intervention. No deaths, major adverse cardiac events, or malignancies were reported during the study.
Approached for an independent comment, Marius-Anton Ionescu, MD, PhD, from the University Hospital Saint Louis, Paris, who specializes in psoriasis, told this news organization that the new development with JNJ-2113 “is really promising.”
Treatment for plaque psoriasis has improved to the point where some biologics, such as risankizumab (Skyrizi), only require patients to have “four shots a year,” he says. “This is the future of psoriasis treatment; it might go down to two shots a year” – a regimen that will be easier than taking an oral medication once or twice a day.
“But it’s good to have an oral option because you will always have some patients who say: ‘Shots are not for me, I’m afraid,’ ” he says.
However, Dr. Ionescu noted that if JNJ-2113 were to pass phase 3 trials, it might face stiff competition from the selective tyrosine kinase 2 (TYK2) inhibitor deucravacitinib (Sotyktu), which the U.S. Food and Drug Administration approved for use in adults with moderate to severe plaque psoriasis last September. “It has very good results and is the first oral therapy that is comparable with biologics for plaque psoriasis,” he says.
But Dr. Bissonnette remains hopeful for the future. “I think JNJ-2113 goes way beyond psoriasis because this type of strategy using oral peptide–blocking receptors could be used in other immune-mediated diseases, including atopic dermatitis and other diseases outside of dermatology.” In addition to running a phase 3 study for moderate to severe plaque psoriasis, Janssen is planning to initiate a phase 2b clinical trial of JNJ-2113 in adults with ulcerative colitis.
The study was funded by Janssen. Dr. Bissonnette reports consulting and investigating for Janssen, and being on advisory panels and receiving research funding from multiple other pharmaceutical companies. Dr. Ionescu is an investigator for Psoriasis National Register France Psobioteq (no honoraria), and an investigator and speaker for Uriage cosmetics (honoraria).

PASI 90 and 100 were among some of the secondary outcomes measured. Similar to the primary outcome of PASI 75, all treatment groups demonstrated a statistically significant dose-response in PASI 90, compared with placebo. For those on the highest dose of JNJ-2113, 59.5% and 40.5% achieved PASI 90 and PASI 100, respectively, by week 16. The corresponding figures for those receiving placebo were 2.3% and 0%.
The safety profile for JNJ-2113 across all doses was similar to that of placebo, with no evidence of a dose-dependent increase in the occurrence of adverse events (AEs). The most frequently reported AEs were COVID-19 and nasopharyngitis. There were three serious AEs (COVID-19, infected cyst, suicide attempt) among those on the active drug, but the investigators assessed that they were not related to the study intervention. No deaths, major adverse cardiac events, or malignancies were reported during the study.
Approached for an independent comment, Marius-Anton Ionescu, MD, PhD, from the University Hospital Saint Louis, Paris, who specializes in psoriasis, told this news organization that the new development with JNJ-2113 “is really promising.”
Treatment for plaque psoriasis has improved to the point where some biologics, such as risankizumab (Skyrizi), only require patients to have “four shots a year,” he says. “This is the future of psoriasis treatment; it might go down to two shots a year” – a regimen that will be easier than taking an oral medication once or twice a day.
“But it’s good to have an oral option because you will always have some patients who say: ‘Shots are not for me, I’m afraid,’ ” he says.
However, Dr. Ionescu noted that if JNJ-2113 were to pass phase 3 trials, it might face stiff competition from the selective tyrosine kinase 2 (TYK2) inhibitor deucravacitinib (Sotyktu), which the U.S. Food and Drug Administration approved for use in adults with moderate to severe plaque psoriasis last September. “It has very good results and is the first oral therapy that is comparable with biologics for plaque psoriasis,” he says.
But Dr. Bissonnette remains hopeful for the future. “I think JNJ-2113 goes way beyond psoriasis because this type of strategy using oral peptide–blocking receptors could be used in other immune-mediated diseases, including atopic dermatitis and other diseases outside of dermatology.” In addition to running a phase 3 study for moderate to severe plaque psoriasis, Janssen is planning to initiate a phase 2b clinical trial of JNJ-2113 in adults with ulcerative colitis.
The study was funded by Janssen. Dr. Bissonnette reports consulting and investigating for Janssen, and being on advisory panels and receiving research funding from multiple other pharmaceutical companies. Dr. Ionescu is an investigator for Psoriasis National Register France Psobioteq (no honoraria), and an investigator and speaker for Uriage cosmetics (honoraria).

JAK inhibitors efficacious for atopic dermatitis in Asian patients, study finds
SINGAPORE – conducted in Singapore has found.
“Abrocitinib and upadacitinib surprisingly appeared to have better treatment efficacy compared to baricitinib,” said study lead Yik Weng Yew, MD, PhD, MPH, deputy head of research at Singapore’s National Skin Centre (NSC), who presented the results at the 25th World Congress of Dermatology. “But overall, as a group, I think they show a very good treatment response, as well as a good effect on itch response.”
JAK inhibitors are used to treat a variety of inflammatory diseases including alopecia areata, rheumatoid arthritis, and inflammatory bowel disease. Although treatment for severe eczema was previously limited to topical steroids and oral immunosuppressants, there are now two oral JAK inhibitors – abrocitinib and upadacitinib – approved in 2022 by the Food and Drug Administration for treating AD, which affects up to 2.4% of the global population. (A topical formulation of ruxolitinib, a JAK inhibitor, was approved for AD in 2021.)
The Singapore study is one of the few that have examined the safety and efficacy of JAK inhibitors for treatment of AD in a non-White population.
Chinese population
For the 12-week trial, conducted in 2022, Dr. Yew and associates recruited 35 patients from the NSC. More than half of participants (64%) were men and most (96%) were of Chinese ethnicity. Four of every five patients had previously received systemic agents: 17% had been treated with one systemic agent, 18.9% with two, 15.1% with three, 22.6% with four, and 3.8% with five. The most commonly used agents were cyclosporine (62.3%), methotrexate (47.2%), azathioprine (39.6%), and dupilumab (35.8%).
“The switch in therapy could have been a result of inadequate efficacy or cost reasons because in Singapore patients pay out of pocket for AD treatments,” said Dr. Yew.
Additionally, he offered a caveat on the profile of participants: “Perhaps they were more difficult atopic eczema patients, and therefore, the efficacy [of JAK inhibitors] might be a bit different.”
Clearer skin, less itch
Patients received one of the three study drugs: baricitinib (66%), abrocitinib (21%), and upadacitinib (13%). The distribution was “affected by reimbursement patterns and availability of the drug,” explained Dr. Yew.
They were assessed at weeks 4 and 12. By study end, the proportion of patients who self-reported an improvement in their condition was 100% for upadacitinib, 90% for abrocitinib, and 69% for baricitinib.
Scores on the Investigator Global Assessment (IGA) also improved with treatment. Patients in the baricitinib group saw their mean score fall from 4.0 to 3.0 by week 4, then to 2.0 by week 12. With upadacitinib and abrocitinib, “you can see that there is a nice decrease in IGA responses,” said Dr. Yew, referring to the larger improvement in scores experienced by patients on those two treatments. For patients on upadacitinib, IGA decreased from 3.5 to 2 at 4 weeks, then to 0.5 at 12 weeks, while those taking abrocitinib had their scores drop from 4.0 to 2.0 at 4 weeks, then to 1.0 at 12 weeks.
When it came to itch reduction, the abrocitinib group experienced the biggest reduction, with a median reduction of 5.5 points in itch score. Median reduction in itch score was 4 points for the other two groups. “Oral JAK inhibitors appear to have a good effect on itch response,” said Dr. Yew.
However, the researchers observed no significant reduction in percentage of body surface area affected, the last outcome assessed.
The most commonly reported adverse events were increased creatine kinase levels (11.3% of patients), increased LDL cholesterol levels (9.4%), and herpes zoster (9.4%). Those in the abrocitinib reported a higher number of these adverse events, compared with the other two treatment groups. (There were no herpes zoster cases among those taking baricitinib.)
For herpes zoster, Dr. Yew said “the common recommendation” is to give the inactivated shingles vaccine. “But the problem is that, number one, these patients would have probably failed multiple agents so they probably can’t wait for you to vaccinate before you initiate treatment.”
In addition, people in Singapore have to pay out-of-pocket for the two vaccine doses, “which is probably a month’s worth of medication,” he noted. “So we have a lot of resistance from patients.”
Additionally, Dr. Yew noted that contrary to what has previously been reported in the literature, there were few complaints of acne as a side effect in the Singaporean study population.
Toward greater representation
Dr. Yew pointed out that the study was limited by a few factors: neither the Eczema Area and Severity Index or Scoring of Atopic Dermatitis index data was used, and the study population was small and not representative of the real world.
Still, the new findings contribute to the overall safety and efficacy profile of JAK inhibitors in AD, which has so far been scarce in non-White populations.
“In Western studies, unfortunately, the representation of the population of skin of color or different ethnicities is underrepresented,” said Yousef Binamer, MD, chair of the dermatology department at King Faisal Specialist Hospital, Riyadh, Saudi Arabia, when approached for an independent comment on the results.
“This is now why researchers are looking into specific groups to study them,” which he pointed out, is crucial because “the immunophenotyping of AD is different for each background.”
The incidence and severity of AD tend to be higher in Asian and Middle Eastern populations, for instance, he noted. “It’s very common in Asia, and not so common in very white skin. I did my training in Canada so I see the difference,” said Dr. Binamer. “Asian people tend to be more itchy and have a tendency to scar on pigmentation.” Whereas White people “usually do not have this issue.”
“So I think real-world evidence of JAK inhibitors in the other populations is important,” he said. Studies such as the one conducted in Singapore, as well as the recently reported QUARTZ3 study, which examined the use of the JAK inhibitor ivarmacitinib in 256 Chinese patients with AD, are helping to pave the way.
The study was independently supported. Dr. Yew and Dr. Binamer have reported no relevant financial relationships.

Study finds subcutaneous spesolimab reduces flares in patients with GPP
SINGAPORE – presented in a late-breaker session at the World Congress of Dermatology,
In the phase 2b study, patients who received the high-dose regimen (a 600-mg subcutaneous loading dose, then 300-mg SC every 4 weeks) of spesolimab experienced 84% fewer GPP fares over 48 weeks, compared with those on placebo, reported Bruce Strober, MD, PhD, Central Connecticut Dermatology, Cromwell, and clinical professor of dermatology, Yale University, New Haven, Conn. “Additionally, no flares occurred after week 4, and this, in turn, translated into improved patient outcomes.”
GPP is a rare, chronic, systemic neutrophilic skin disease. The resulting flares, characterized by painful pustules all over the body, can lead to sepsis, shock, and other life-threatening complications. “People who have it are considerably burdened by it, so targeted therapy of this disease is incredibly important because it leads to lessened morbidity and, importantly, mortality for these patients,” Dr. Strober said.
“It’s important not only to treat the flares but also to prevent them,” he noted.
The intravenous formulation of spesolimab (Spevigo) was approved for the treatment of GPP flares in adults by the Food and Drug Administration in September 2022. It is now authorized in nearly 40 countries, including Japan, China, and the European Union.
The phase 2 Effisayil 2 study presented at the meeting evaluated the subcutaneous formulation of spesolimab. Data on subcutaneous spesolimab has been submitted to the FDA, and has received breakthrough therapy designation, according to the manufacturer, Boehringer Ingelheim.
Flare prevention
In the study, 123 patients with GPP were randomly assigned 1:1:1:1 to one of four groups: high-dose spesolimab, medium-dose (600-mg SC loading dose, then 300-mg SC every 12 weeks), low-dose (300-mg SC loading dose, then 150-mg SC every 12 weeks), or placebo. In the event of a flare during the randomized treatment period, a patient was administered a single, 900-mg intravenous dose of spesolimab.
Nearly two-thirds of the participants were female and nearly two-thirds were Asian, with a mean age of about 39-43 years.
The mean numbers of GPP flares experienced annually by those in the low-, medium-, and high-dose spesolimab groups were 2.7, 1.9, and 2.4, respectively (2.4% in the placebo group). Fewer than a third had concurrent plaque psoriasis at baseline. Most (48.4%-63.3%) did not have an IL-36RN mutation.
Additionally, the Generalized Pustular Psoriasis Physician Global Assessment total score was 1 in 74.2%-93.5% of participants, and 0 in the remainder.
The primary study endpoint was the time to GPP flare by week 48. The risk of developing a flare among those on high-dose spesolimab was 84% lower, compared with that of those on placebo (hazard ratio, 0.16; 95% confidence interval, 0.05-0.54; P = .0005). No patients on the high dose had a flare after the 4th week of the study.
Similarly, for the secondary endpoint (occurrence of at least one GPP flare by week 48). Dr. Strober and his colleagues reported that high-dose spesolimab was superior to placebo with a risk difference of -39% (95% CI, –0.62 to –0.16; P = .0013). By contrast, the risk differences for the medium- and low-dose spesolimab arms were –0.23 (95% CI, –0.46 to 0.01) and -0.31 (95% CI, –0.54 to –0.08), respectively.
The safety profile of subcutaneous spesolimab across all three doses was similar to that of placebo, and there was no dose-dependent trend. Reported adverse events (AEs) were mild. There were five (5.4%) AEs leading to discontinuation of the drug in the medium- and high-dose groups, but none in the low-dose group. Overall, there were nine (9.7%) serious AEs reported in the spesolimab groups, and three (10%) in the high-dose group; no deaths occurred on any dose.
Participants most often reported injection-site erythema, reported in 13 (14%) of the patients on spesolimab versus 1 (3.3%) of those on placebo.
“Overall, the study demonstrates that subcutaneous spesolimab is effective at controlling GPP flares, especially at a high dose relative to placebo, and supports subcutaneous spesolimab for the therapy for GPP flare prevention,” Dr. Strober said at the meeting.
Targeting the IL-36 pathway
In a comment, Todd Schlesinger, MD, Clinical Research Center of the Carolinas, Charleston, S.C., who moderated the session, said: “It’s very exciting to be able to have a subcutaneous version of the medication.”
“I think the IL-36 is a great pathway,” he said, referring to the signaling pathway within the immune system that is central to the pathogenesis of GPP and several other autoinflammatory diseases.
However, Dr. Schlesinger said that he would have liked to have seen data on how many patients ended up treated with intravenous spesolimab.
He added that he would like future studies of subcutaneous spesolimab to examine the effect in different populations that vary by parameters such as weight, race, and disease severity. “Just seeing how somebody who’s flaring five times a year and you give them this medication and they’re now flaring once a year – that’s interesting data that we might like to know in the future.”
Other than for preventing GPP flares, spesolimab is being studied for treating other IL-36–mediated skin diseases, such as palmoplantar pustulosis.
The study was funded by Boehringer Ingelheim; both Dr. Strober and Dr. Schlesinger do research and consulting for BI, and receive funding from multiple other pharmaceutical companies.

He added that he would like future studies of subcutaneous spesolimab to examine the effect in different populations that vary by parameters such as weight, race, and disease severity. “Just seeing how somebody who’s flaring five times a year and you give them this medication and they’re now flaring once a year – that’s interesting data that we might like to know in the future.”
Other than for preventing GPP flares, spesolimab is being studied for treating other IL-36–mediated skin diseases, such as palmoplantar pustulosis.
The study was funded by Boehringer Ingelheim; both Dr. Strober and Dr. Schlesinger do research and consulting for BI, and receive funding from multiple other pharmaceutical companies.

SINGAPORE – presented in a late-breaker session at the World Congress of Dermatology,
In the phase 2b study, patients who received the high-dose regimen (a 600-mg subcutaneous loading dose, then 300-mg SC every 4 weeks) of spesolimab experienced 84% fewer GPP fares over 48 weeks, compared with those on placebo, reported Bruce Strober, MD, PhD, Central Connecticut Dermatology, Cromwell, and clinical professor of dermatology, Yale University, New Haven, Conn. “Additionally, no flares occurred after week 4, and this, in turn, translated into improved patient outcomes.”
GPP is a rare, chronic, systemic neutrophilic skin disease. The resulting flares, characterized by painful pustules all over the body, can lead to sepsis, shock, and other life-threatening complications. “People who have it are considerably burdened by it, so targeted therapy of this disease is incredibly important because it leads to lessened morbidity and, importantly, mortality for these patients,” Dr. Strober said.
“It’s important not only to treat the flares but also to prevent them,” he noted.
The intravenous formulation of spesolimab (Spevigo) was approved for the treatment of GPP flares in adults by the Food and Drug Administration in September 2022. It is now authorized in nearly 40 countries, including Japan, China, and the European Union.
The phase 2 Effisayil 2 study presented at the meeting evaluated the subcutaneous formulation of spesolimab. Data on subcutaneous spesolimab has been submitted to the FDA, and has received breakthrough therapy designation, according to the manufacturer, Boehringer Ingelheim.
Flare prevention
In the study, 123 patients with GPP were randomly assigned 1:1:1:1 to one of four groups: high-dose spesolimab, medium-dose (600-mg SC loading dose, then 300-mg SC every 12 weeks), low-dose (300-mg SC loading dose, then 150-mg SC every 12 weeks), or placebo. In the event of a flare during the randomized treatment period, a patient was administered a single, 900-mg intravenous dose of spesolimab.
Nearly two-thirds of the participants were female and nearly two-thirds were Asian, with a mean age of about 39-43 years.
The mean numbers of GPP flares experienced annually by those in the low-, medium-, and high-dose spesolimab groups were 2.7, 1.9, and 2.4, respectively (2.4% in the placebo group). Fewer than a third had concurrent plaque psoriasis at baseline. Most (48.4%-63.3%) did not have an IL-36RN mutation.
Additionally, the Generalized Pustular Psoriasis Physician Global Assessment total score was 1 in 74.2%-93.5% of participants, and 0 in the remainder.
The primary study endpoint was the time to GPP flare by week 48. The risk of developing a flare among those on high-dose spesolimab was 84% lower, compared with that of those on placebo (hazard ratio, 0.16; 95% confidence interval, 0.05-0.54; P = .0005). No patients on the high dose had a flare after the 4th week of the study.
Similarly, for the secondary endpoint (occurrence of at least one GPP flare by week 48). Dr. Strober and his colleagues reported that high-dose spesolimab was superior to placebo with a risk difference of -39% (95% CI, –0.62 to –0.16; P = .0013). By contrast, the risk differences for the medium- and low-dose spesolimab arms were –0.23 (95% CI, –0.46 to 0.01) and -0.31 (95% CI, –0.54 to –0.08), respectively.
The safety profile of subcutaneous spesolimab across all three doses was similar to that of placebo, and there was no dose-dependent trend. Reported adverse events (AEs) were mild. There were five (5.4%) AEs leading to discontinuation of the drug in the medium- and high-dose groups, but none in the low-dose group. Overall, there were nine (9.7%) serious AEs reported in the spesolimab groups, and three (10%) in the high-dose group; no deaths occurred on any dose.
Participants most often reported injection-site erythema, reported in 13 (14%) of the patients on spesolimab versus 1 (3.3%) of those on placebo.
“Overall, the study demonstrates that subcutaneous spesolimab is effective at controlling GPP flares, especially at a high dose relative to placebo, and supports subcutaneous spesolimab for the therapy for GPP flare prevention,” Dr. Strober said at the meeting.
Targeting the IL-36 pathway
In a comment, Todd Schlesinger, MD, Clinical Research Center of the Carolinas, Charleston, S.C., who moderated the session, said: “It’s very exciting to be able to have a subcutaneous version of the medication.”
“I think the IL-36 is a great pathway,” he said, referring to the signaling pathway within the immune system that is central to the pathogenesis of GPP and several other autoinflammatory diseases.
