The interleukin-17A antagonist ixekizumab has shown sustained efficacy over 4 years of treatment in patients with moderate to severe plaque psoriasis, according to a study published in the Journal of the European Academy of Dermatology and Venereology.

The UNCOVER-3 trial was a double-blind, multicenter, phase 3 study in 1,346 individuals with moderate to severe psoriasis who were randomized to placebo, 80 mg of ixekizumab every 2 or 4 weeks, or 50 mg of etanercept twice weekly. At week 12, all patients were transferred to 80 mg of ixekizumab every 4 weeks for the long-term extension period, and after 60 weeks, some were dose adjusted to 80 mg every 2 weeks.

At week 204, 48.3% of the 385 patients who were receiving treatment either every 2 or 4 weeks achieved Psoriasis Area and Severity Index (PASI) 100 according to the modified nonresponder imputation method to summarize efficacy – in which patients who drop out of the study are counted as nonresponders – 66.4% achieved PASI 90 and 82.8% achieved PASI 75.

Using the as-observed method for assessing efficacy, 67.1% of patients achieved PASI 100, 87.8% achieved PASI 90, and 98.2% achieved PASI 75. Using the multiple-imputation method, those same figures were 52.7%, 73.3%, and 94.8% respectively.

They also saw consistently high response rates according to the static Physician’s Global Assessment (sPGA) score, which goes from 0 (clear) to 5 (severe disease). Using the as-observed, multiple imputation and modified nonresponder imputation methods, 68.9%, 54.6%, and 49.7% of patients respectively achieved a score of 0.

The study also saw complete resolution in 95.8% of patients with baseline palmoplantar involvement, 75.9% of those with baseline nail involvement, and 87.1% of those with scalp involvement, using the as-observed method.

“These results corroborate the results that were reported previously in patients with moderate to severe psoriasis,” wrote Mark G. Lebwohl, MD, professor and chair of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York, and coauthors. “Sustained high response was observed with all the efficacy parameters such as PASI 75, 90, 100, and sPGA (0) or (0, 1), regardless of the statistical analyses ... performed.”

The majority of adverse events were mild or moderate, but serious adverse events were seen in 18.1% of patients in the long-term extension and 9.4% of patients stopped taking the study drug because of adverse events.

The most frequently reported adverse events of special interest were infections, such as nasopharyngitis (28.5% of patients), upper respiratory tract infections (10.8%), and Candida infection (5.2%). However, clinically significant neutropenia only occurred in 0.7% of patients, and malignancies occurred in 2.2% of patients.

“These safety findings support the consistency in the safety profile of [ixekizumab] treatment with no new signals occurring even after the longer exposure,” the authors wrote.

The study was funded by Eli Lilly, which manufactures ixekizumab. Two authors were employees of Eli Lilly and own company stocks. The remaining three authors reported receiving research funding and consultancies from different pharmaceutical companies, including Eli Lilly.

According to a press release from Pfizer, approval for Abrilada was based on review of a comprehensive data package demonstrating biosimilarity of the drug to the reference product. This included data from a clinical comparative study, which found no clinically meaningful difference between Abrilada and the reference in terms of efficacy, safety, and immunogenicity in patients with moderate to severe rheumatoid arthritis (RA). In addition to RA, Abrilada is indicated for juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, adult Crohn’s disease, ulcerative colitis, and plaque psoriasis.

Common adverse events in adalimumab clinical trials included infection, injection-site reactions, headache, and rash.

Pfizer said that it “is working to make Abrilada available to U.S. patients as soon as feasible based on the terms of our agreement with AbbVie [the manufacturer of Humira]. Our current plans are to launch in 2023.”

LAS VEGAS – Based on the best available data to date, certolizumab pegol is likely the best treatment choice for women with psoriasis who become pregnant, Francisco A. Kerdel, BSc, MBBS, said at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.

Doug Brunk/MDedge News

Dr. Kerdel, professor and vice chair of the department of dermatology at Florida International University, Miami, noted that, while tumor necrosis factor (TNF)–alpha inhibitors are category B drugs, inadequate data exist regarding lactation and exposure throughout pregnancy. “Rates of malformations and spontaneous abortions with therapy are similar to those in the general population, higher concentrations of infliximab and adalimumab have been found in infant and cord blood, compared with certolizumab pegol,” an anti-TNF biologic, he said.

In a prospective, postmarketing, multicenter pharmacokinetic study, researchers found a lack of placental transfer of certolizumab pegol during pregnancy (Ann Rheum Dis. 2018;77:228-33). Specifically, certolizumab levels were below the lower limit of quantification (less than 0.032 mcg/mL) in 13 of 14 infant samples at birth and in all infant samples at weeks 4 and 8. Only one infant had a minimal certolizumab level at birth (infant/mother ratio of 0.0009). No antibodies were detected at any time point during the study. Safety data in mothers were in line with the known safety profile of certolizumab and pregnancy profile of these underlying diseases. Adverse events experienced by the infants did not show any patterns or clusters of events suggesting a specific safety signal in children.

In a separate postmarketing pharmacokinetic study, investigators evaluated the transfer of certolizumab into breast milk (Ann Rheum Dis. 2017;76:1890-6). They found that the average daily infant dose of certolizumab was minimal. Specifically, the highest concentration of certolizumab in breast milk (0.0758 mcg/mL) was less than 1% of the expected mean plasma trough concentration of a therapeutic dose.

How do TNF-alpha inhibitors fare in the pediatric population? In a retrospective study of 390 children with psoriasis treated at 20 centers in the United States, Canada, and Europe, researchers evaluated the safety of systemic agents (JAMA Dermatol. 2017;153[11]:1147-57). Most (69%) were prescribed methotrexate, followed by biologics, acitretin, cyclosporine, and fumaric acid. Drug discontinuation (because of adverse events), which is sometimes used as an efficacy parameter, occurred in 12% of those who were on methotrexate, compared with 3% of those on biologics, 67% of those on acitretin, and 68% of those on fumaric acid.

At the other end of the age spectrum, biologic therapy is generally effective and well tolerated in elderly patients. “Sometimes, they may be more effective than other traditional drugs,” Dr. Kerdel said. “We’re a little bit concerned about immunosenescence, which can increase the risk for severe infections and malignancies. And, 90% of elderly patients with psoriasis may have comorbidities that need to be taken into account when treating psoriasis.”

Other factors come into play when choosing the right anti-TNF agent, including weight. While clinical trials show efficacy across weight groups, infliximab has weight-based dosing, “which may make it a better choice,” Dr. Kerdel said. “Patients taking etanercept may need a biweekly dose.”

Treatment flexibility also comes into play. For example, stopping therapy because of an infection or surgery may be problematic in drugs with a long half-life. Then there’s the issue of patient preference. “Some people don’t want to be injected frequently,” he said. “Some people don’t want to be injected at all and may require a simpler dosing regimen.”

Optimizing anti-TNF-alpha treatment starts with recognizing that there is a loss of response over time, Dr. Kerdel said, “or there may not be a response at all.” Contributing factors may include immunogenicity, suboptimal dosing, and poor patient adherence. In order to optimize treatment, clinicians can try switching agents or combination therapy, and explore continuous versus intermittent dosing.

“We really don’t have good data on the best protocol for switching treatment after failure of an anti-TNF-alpha agent,” he added. In cases of primary and secondary treatment failure, there is no consensus or guidelines on which second-line agent to use, nor good data on which measures to use.

No evidence-based guidelines are available for screening and monitoring patients receiving biologic therapy for psoriasis, either. “Evidence is strongest [grade B] for tuberculosis screening in patients treated with biologic agents,” Dr. Kerdel said. “Among known hepatitis B virus carriers, consider monitoring liver function tests and viral load [grade C]. High-grade evidence is lacking to support other routine testing. Physicians should use clinical judgment when screening and monitoring patients.”

He concluded his presentation by noting that there are a number of biosimilar agents available or in the pipeline for infliximab, adalimumab, and etanercept. This raises a number of questions for current and future consideration. For one, “will biosimilars show the same long-term efficacy and safety as the innovator products?” he asked. “Real-world, postmarketing, and registry data are needed. Will biosimilar agents offer significant cost benefits? Will biosimilar labeling be adequately transparent? Will we find biomarkers to help us target biologic agents to specific patients and subtypes of psoriasis?”

Dr. Kerdel reported that he is a member of the speaker’s bureau for AbbVie, Amgen, Celgene, Janssen, Novartis, Lilly, Leo, Ortho, and Novartis. He has also received grant/research support from AbbVie, Amgen, AstraZeneca, Celgene, Janssen, Leo, Lilly, Menlo Therapeutics, Novartis, Pfizer, and XBiotech.

LAS VEGAS – Narrowband UVB phototherapy remains an effective and generally safe treatment for psoriasis, according to Kenneth B. Gordon, MD, professor and chair of dermatology at the Medical College of Wisconsin, Milwaukee.

Doug Brunk/MDedge News

At the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar, Dr. Gordon said that he uses phototherapy most in patients “who can’t get to all of the spots without it,” and in those whose disease is not having a huge impact on day-to-day life. “In my experience it’s best in people with thinner plaques, though I have some question over whether we can figure out if morphology really does correlate to respond to phototherapy,” he added. “We’re in the process of conducting a study to try and figure that out.”

From an immunologic standpoint, UVB decreases responsiveness of the interleukin-17 pathway and increases both cutaneous and circulating FoxP3+ cells, he said. Activation of p38 mitogen–activated protein kinase during phototherapy inhibits proinflammatory T-cell activation. In Dr. Gordon’s opinion, phototherapy is absolutely contraindicated in patients who have a photosensitivity reaction related to the UVB spectrum, while it is relatively contraindicated in those at high risk for skin cancer, including patients with multiple squamous cell carcinomas and those who have undergone organ transplantation. “I would argue that [the use of] photosensitizing drugs are not a contraindication,” he said. “Would I prefer that someone who’s had 54 [squamous cell carcinomas] not use phototherapy? Of course. But if it’s the only weapon I have, I’ll use it.”

Although clinicians have used phototherapy for about 100 years, early standards for clinical trials were different, compared with the rigor required of those conducted in the current era. Outcomes were not standardized, he said, and they were generally smaller trials that did not incorporate proper monitoring of adverse events. “Even with these weaknesses, we can get a general impression of how well UV works,” he said. In a 6-week, split-body trial of 11 patients from 20 years ago, researchers were able to induce clinical clearing in 82% of patients after narrowband UVB (the type most commonly used today), but in only 9% of patients after broadband UVB treatment (P less than .01) (J Am Acad Dermatol. 1999 Jun;40[6 Pt 1]:893-900).

Most clinicians commence narrowband UVB phototherapy treatment with three sessions per week and safely increase the dose to reach an effective level. Erythema can develop with overdosing. “If a patient can only come in twice weekly [for phototherapy treatment], that is okay,” Dr. Gordon said. “It takes a longer time getting to treatment goals. In my opinion, going down to once a week during the escalating phase of using phototherapy doesn’t work. Three times a week is better than twice a week during the escalating phase, but one time a week isn’t enough.”

Even for maintenance therapy, it remains a question whether limiting phototherapy to once every 2 or 4 weeks is sufficient for disease control. “I let the patient choose, but I like to go down to no less than once a week and hold people steady at that dose,” he said.

Purported risks of narrowband UVB phototherapy include photoaging, sunburn, herpes simplex virus reactivation, loss of the patient’s productive time, and development of skin cancer. “I don’t think we have good data about the effect of phototherapy on photoaging,” Dr. Gordon said. “Loss of productive time is my single biggest [complaint]. People are having trouble getting to work and having bosses who are not pleased with them [leaving work for treatment].”

As for the association between phototherapy and skin cancer, he noted that published studies that show statistical differences all incorporate psoralen-UVA photochemotherapy into their analyses. “There’s really no study that has demonstrated a significant impact on nonmelanoma skin cancers with the use of phototherapy [alone],” Dr. Gordon said. A British study of 3,867 psoriasis patients found no significant association between narrowband UVB treatment and basal cell cancer, squamous cell cancer, or melanoma (Br J Dermatol. 2008 Sep;159[4]:931-5). However, among those who also were treated with psoralen-UVA photochemotherapy, there was a small increase in basal cell cancer.

In a more recent Swedish study of 162 psoriasis patients who were treated with UVB phototherapy, researchers found that, after controlling for age, the risk of skin cancer was associated with the number of treatments, but not with the type of UVB lamp used (Acta Derm Venereol. 2014 Jul;94[4]:425-30). They reported that overall, the risk of malignancy in the UVB-treated patients did not exceed that in the general population.

Dr. Gordon concluded his presentation by noting that home-based UVB phototherapy is gaining in popularity and is comparable with in-office UVB in terms of accuracy and efficacy (BMJ. 2009;338:b1542). Because of convenience and decreased time away from work, he said, “it’s easier for patients ... and it’s probably cheaper in the long run.” The National Psoriasis Foundation web site includes a list of home UVB equipment.

Dr. Gordon disclosed that he is a consultant with AbbVie, Almirall, Amgen, Bristol-Meyers Squibb, Celgene, Dermavant, Eli Lilly, Janssen, Leo, Novartis, Ortho Dermatologics, Pfizer, Sun Pharma, and UCB. He has also received grant/research support from AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, and Novartis.

LAS VEGAS – Narrowband UVB phototherapy remains an effective and generally safe treatment for psoriasis, according to Kenneth B. Gordon, MD, professor and chair of dermatology at the Medical College of Wisconsin, Milwaukee.

At the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar, Dr. Gordon said that he uses phototherapy most in patients “who can’t get to all of the spots without it,” and in those whose disease is not having a huge impact on day-to-day life. “In my experience it’s best in people with thinner plaques, though I have some question over whether we can figure out if morphology really does correlate to respond to phototherapy,” he added. “We’re in the process of conducting a study to try and figure that out.”

From an immunologic standpoint, UVB decreases responsiveness of the interleukin-17 pathway and increases both cutaneous and circulating FoxP3+ cells, he said. Activation of p38 mitogen–activated protein kinase during phototherapy inhibits proinflammatory T-cell activation. In Dr. Gordon’s opinion, phototherapy is absolutely contraindicated in patients who have a photosensitivity reaction related to the UVB spectrum, while it is relatively contraindicated in those at high risk for skin cancer, including patients with multiple squamous cell carcinomas and those who have undergone organ transplantation. “I would argue that [the use of] photosensitizing drugs are not a contraindication,” he said. “Would I prefer that someone who’s had 54 [squamous cell carcinomas] not use phototherapy? Of course. But if it’s the only weapon I have, I’ll use it.”

Although clinicians have used phototherapy for about 100 years, early standards for clinical trials were different, compared with the rigor required of those conducted in the current era. Outcomes were not standardized, he said, and they were generally smaller trials that did not incorporate proper monitoring of adverse events. “Even with these weaknesses, we can get a general impression of how well UV works,” he said. In a 6-week, split-body trial of 11 patients from 20 years ago, researchers were able to induce clinical clearing in 82% of patients after narrowband UVB (the type most commonly used today), but in only 9% of patients after broadband UVB treatment (P less than .01) (J Am Acad Dermatol. 1999 Jun;40[6 Pt 1]:893-900).

ATLANTA – Guselkumab improved outcomes in psoriatic arthritis patients regardless of past treatment with tumor necrosis factor inhibitors in the phase 3 DISCOVER-1 trial.

The anti-interleukin-23p19 monoclonal antibody is approved in the United States for the treatment of moderate to severe plaque psoriasis (PsO).

The response rates with guselkumab versus placebo were seen regardless of prior TNFi use, he said.

The study included 381 patients with active PsA, defined as three or more swollen joints, three or more tender joints, and C-reactive protein of 0.3 mg/dL or greater despite standard therapies. About 30% were exposed to up to two TNFi therapies and 10% were nonresponders or inadequate responders to those therapies.

Concomitant use of select nonbiologic disease-modifying antirheumatic drugs, oral corticosteroids, and NSAIDs was allowed, and patients with less than 5% improvement in tender plus swollen joints at week 16 could initiate or increase the dose of the permitted medications while continuing study treatment, Dr. Deodhar said.

The mean body surface area with PsO involvement was 13.4%; 42.5% of patients had an IGA of 3-4 for skin involvement. Mean swollen and tender joint counts were 9.8 and 19.3, respectively, indicating a population with moderate to severe disease, he added.

Serious adverse events, serious infections, and death occurred in 2.4%, 0.5%, and 0.3% of patients, respectively.

“Both guselkumab regimens were safe and well tolerated through week 24,” Dr. Deodhar said, noting that the safety profile was consistent with that established in the treatment of PsO and described in the label.

DISCOVER-1 was funded by Janssen Research & Development. Dr. Deodhar reported relationships (advisory board activity, consulting, and/or research grant funding) with several pharmaceutical companies including Janssen. Several coauthors are employees of Janssen.

ATLANTA – A group of patients using a tumor necrosis factor inhibitor safely received the live-attenuated varicella vaccine Zostavax without any cases of herpes zoster in the first 6 weeks after vaccination in the blinded, randomized, placebo-controlled Varicella Zoster Vaccine (VERVE) trial .

According to guidelines from the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices, there is a theoretical concern that patients using a tumor necrosis factor inhibitor (TNFi) and other biologic therapies who receive a live-attenuated version of the varicella vaccine (Zostavax) could become infected with varicella from the vaccine. Patients with RA and psoriatic arthritis as well as other autoimmune and inflammatory conditions who are likely to receive TNFi therapy are also at risk for herpes zoster reactivation, Jeffrey Curtis, MD, professor of medicine in the division of clinical immunology and rheumatology of the University of Alabama at Birmingham, said in his presentation at the annual meeting of the American College of Rheumatology. There also exists a risk for patients receiving low-dose glucocorticoids.

“The challenge, of course, is there’s not a great definition and there certainly is not a well-standardized assay for how immunocompromised someone is, and so that led to the uncertainty in this patient population for this and other live-virus vaccines,” Dr. Curtis said.

Dr. Curtis and colleagues enrolled 627 participants from 33 centers into the VERVE trial. Participants were aged at least 50 years, were taking a TNFi, and had not previously received Zostavax.

Patients in both groups had a mean age of about 63 years and about two-thirds were women. The most common indications for TNFi use in the Zostavax group and the placebo group were RA (59.2% vs. 56.0%, respectively), psoriatic arthritis (24.3% vs. 23.9%), and ankylosing spondylitis (7.2% vs. 8.5%), while the anti-TNF agents used were adalimumab (38.1% vs. 27.4%), infliximab (28.4% vs. 34.2%), etanercept (19.0% vs. 23.5%), golimumab (10.0% vs. 8.1%), and certolizumab pegol (4.5% vs. 6.8%). In addition, some patients in the Zostavax and placebo groups were also taking concomitant therapies with TNFi, such as oral glucocorticoids (9.7% vs. 11.4%).

The researchers randomized participants to receive Zostavax or placebo (saline) and then followed them for 6 weeks, and looked for signs of wild-type or vaccine-strain varicella infection. If participants were suspected to have varicella, they were assessed clinically, underwent polymerase chain reaction testing, and rashes were photographed. At baseline and at 6 weeks, the researchers collected serum and peripheral blood mononuclear cells to determine patient immunity to varicella. After 6 months, participants were unmasked to the treatment arm of the study.

Dr. Curtis and colleagues found no confirmed varicella infection cases at 6 weeks. “To the extent that 0 cases out of 317 vaccinated people is reassuring, there were no cases, so that was exceedingly heartening as a result,” he said.

Out of 20 serious adverse events total in the groups, 15 events occurred before 6 months, including 8 suspected varicella cases in the Zostavax group and 7 in the placebo group. However, there were no positive cases of varicella – either wild type or vaccine type – after polymerase chain reaction tests. Overall, there were 268 adverse events in 195 participants, with 73 events (27.2%) consisting of injection-site reactions. The researchers also found no difference in the rate of disease flares, and found no differences in adverse reactions between groups, apart from a higher rate of injection-site reactions in the varicella group (19.4% vs. 4.2%).

With regard to immunogenicity, the humoral immune response was measured through IgG, which showed an immune response in the varicella group at 6 weeks (geometric mean fold ratio, 1.33; 95% confidence interval, 1.18-1.51), compared with the placebo group (GMFR, 1.02; 95% CI, 0.91-1.14); cell-mediated immune response was measured by interferon-gamma, which also showed an immune response in the live-vaccine group (GMFR, 1.49; 95% CI, 1.14-1.94), compared with participants who received placebo (GMFR, 1.14; 95% CI, 0.87-1.48). In preliminary 1-year data, IgG immune response was elevated in the varicella group (GMFR, 1.46; 95% CI, 1.08-1.99), but there was no elevated immune response for interferon-gamma (GMFR, 0.78; 95% CI, 0.49-1.25).

“I think the trial is encouraging not only for its result with the live zoster vaccine and TNF-treated patients, but also challenge the notion that, if you need to, a live-virus vaccine may in fact be able to be safely given to people with autoimmune and inflammatory diseases, even those treated with biologics like tumor necrosis factor inhibitors,” Dr. Curtis said.

As patients in VERVE consented to long-term follow-up in health plan claims and EHR data, it will be possible to follow these patients in the future to assess herpes zoster reactivation. Dr. Curtis also noted that a new trial involving the recombinant, adjuvanted zoster vaccine (Shingrix) is currently in development and should begin next year.

The VERVE trial was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Curtis reported serving as a current member of the Center for Disease Control and Prevention’s Advisory Committee on Immunization Practices Herpes Zoster Work Group. He and some of the other authors reported financial relationships with many pharmaceutical companies.

“The challenge, of course, is there’s not a great definition and there certainly is not a well-standardized assay for how immunocompromised someone is, and so that led to the uncertainty in this patient population for this and other live-virus vaccines,” Dr. Curtis said.

Dr. Curtis and colleagues enrolled 627 participants from 33 centers into the VERVE trial. Participants were aged at least 50 years, were taking a TNFi, and had not previously received Zostavax.

Patients in both groups had a mean age of about 63 years and about two-thirds were women. The most common indications for TNFi use in the Zostavax group and the placebo group were RA (59.2% vs. 56.0%, respectively), psoriatic arthritis (24.3% vs. 23.9%), and ankylosing spondylitis (7.2% vs. 8.5%), while the anti-TNF agents used were adalimumab (38.1% vs. 27.4%), infliximab (28.4% vs. 34.2%), etanercept (19.0% vs. 23.5%), golimumab (10.0% vs. 8.1%), and certolizumab pegol (4.5% vs. 6.8%). In addition, some patients in the Zostavax and placebo groups were also taking concomitant therapies with TNFi, such as oral glucocorticoids (9.7% vs. 11.4%).

The researchers randomized participants to receive Zostavax or placebo (saline) and then followed them for 6 weeks, and looked for signs of wild-type or vaccine-strain varicella infection. If participants were suspected to have varicella, they were assessed clinically, underwent polymerase chain reaction testing, and rashes were photographed. At baseline and at 6 weeks, the researchers collected serum and peripheral blood mononuclear cells to determine patient immunity to varicella. After 6 months, participants were unmasked to the treatment arm of the study.

Dr. Curtis and colleagues found no confirmed varicella infection cases at 6 weeks. “To the extent that 0 cases out of 317 vaccinated people is reassuring, there were no cases, so that was exceedingly heartening as a result,” he said.

Out of 20 serious adverse events total in the groups, 15 events occurred before 6 months, including 8 suspected varicella cases in the Zostavax group and 7 in the placebo group. However, there were no positive cases of varicella – either wild type or vaccine type – after polymerase chain reaction tests. Overall, there were 268 adverse events in 195 participants, with 73 events (27.2%) consisting of injection-site reactions. The researchers also found no difference in the rate of disease flares, and found no differences in adverse reactions between groups, apart from a higher rate of injection-site reactions in the varicella group (19.4% vs. 4.2%).

With regard to immunogenicity, the humoral immune response was measured through IgG, which showed an immune response in the varicella group at 6 weeks (geometric mean fold ratio, 1.33; 95% confidence interval, 1.18-1.51), compared with the placebo group (GMFR, 1.02; 95% CI, 0.91-1.14); cell-mediated immune response was measured by interferon-gamma, which also showed an immune response in the live-vaccine group (GMFR, 1.49; 95% CI, 1.14-1.94), compared with participants who received placebo (GMFR, 1.14; 95% CI, 0.87-1.48). In preliminary 1-year data, IgG immune response was elevated in the varicella group (GMFR, 1.46; 95% CI, 1.08-1.99), but there was no elevated immune response for interferon-gamma (GMFR, 0.78; 95% CI, 0.49-1.25).

“I think the trial is encouraging not only for its result with the live zoster vaccine and TNF-treated patients, but also challenge the notion that, if you need to, a live-virus vaccine may in fact be able to be safely given to people with autoimmune and inflammatory diseases, even those treated with biologics like tumor necrosis factor inhibitors,” Dr. Curtis said.

As patients in VERVE consented to long-term follow-up in health plan claims and EHR data, it will be possible to follow these patients in the future to assess herpes zoster reactivation. Dr. Curtis also noted that a new trial involving the recombinant, adjuvanted zoster vaccine (Shingrix) is currently in development and should begin next year.

The VERVE trial was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Curtis reported serving as a current member of the Center for Disease Control and Prevention’s Advisory Committee on Immunization Practices Herpes Zoster Work Group. He and some of the other authors reported financial relationships with many pharmaceutical companies.

Psoriasis management in children involves attention not only to treatment of the physical condition but also psychosocial wellness and quality of life, according to a new clinical guideline on the management of pediatric psoriasis from the American Academy of Dermatology and the National Psoriasis Foundation.

Psoriasis affects approximately 1% of children, either alone or associated with comorbid conditions such as psoriatic arthritis (PsA), wrote Alan Menter, MD, of Baylor University Medical Center, Dallas, and coauthors of the guideline.

In the guideline, published in the Journal of the American Academy of Dermatology, the multidisciplinary work group identified screening tools to measure disease severity, strategies for management of comorbidities, and the safety and effectiveness of topical, systemic, and phototherapy treatments.

To assess disease severity, the work group recommended not only the use of body surface area (BSA), similar to measurement of severity in adults, but also the use of the Children’s Dermatology Life Quality Index, a 10-question quality of life survey, as BSA alone does not account for the potential negative impact of the disease on quality of life in terms of physical, emotional, social, and psychological function.

“For example, a child with psoriasis limited to the face or the entire scalp does not have severe disease based on BSA definitions, but if this involvement causes shame, social withdrawal, or bullying, it satisfies criteria for severe disease based on impact beyond the skin,” they said.

The work group stated that a variety of conditions may trigger or exacerbate psoriasis in children, including infections, cutaneous trauma, or physiological, emotional, and environmental stressors.

The majority of children with PsA develop joint inflammation before skin disease, the work group wrote. In addition, children with psoriasis are at increased risk for rheumatoid arthritis, so clinicians may need to distinguish between a combination of psoriasis and musculoskeletal issues and cases of either psoriatic or rheumatoid arthritis in young patients.

The cardiovascular risk factors associated with metabolic syndrome are greater in children with psoriasis, compared with children without psoriasis, the work group noted. In addition, pediatric psoriasis patients have a higher prevalence of obesity than children without psoriasis, and they recommended that children with psoriasis be monitored for the development of obesity, and that obese children with psoriasis should be referred for weight management.

The work group noted that data are insufficient in children to support the link between psoriasis and cardiovascular disease that has been documented in adults with psoriasis. However, “patients with pediatric psoriasis should have American Academy of Pediatrics (AAP)–recommended age-related cardiovascular screening regardless of the presence of signs or symptoms,” they said.

The guideline also recommends screening for dyslipidemia and hypertension according to AAP guidelines and educating pediatric psoriasis patients about the risk of diabetes and regularly screening for diabetes and insulin resistance in those who are obese. Overweight children with psoriasis may be screened at the provider’s discretion, they wrote. Patients with signs of inflammatory bowel disease, which also is associated with psoriasis in adults, should be considered for referral to a gastroenterologist, they noted.

Children with psoriasis should be screened regularly for mental health conditions regardless of age, and they should be asked about substance abuse, according to the guideline, and those with concerns should be referred for additional assessment and management.

The guideline divides treatment of psoriasis in children into three categories: topical, phototherapy and photochemotherapy, and systemic treatments (nonbiologic or biologic).

For topicals, the guideline recommendations include corticosteroids as an off-label therapy, as well as ultra-high-potency topical corticosteroids as monotherapy. Overall, “selection of a therapeutic routine (potency, delivery vehicle, frequency of application) should take into account sites of involvement, type and thickness of psoriasis, age of the patient, total BSA of application, anticipated occlusion, and disease acuity, among other patient-, disease-, and drug-related factors,” the authors wrote. Other topical options included in the recommendations: calcineurin inhibitors, topical vitamin D analogues, tazarotene (off label), anthralin, and coal tar.

Phototherapy has a history of use in psoriasis treatment and remains part of the current recommendations, although data in children are limited, and data on the use of phototherapy for pustular psoriasis in children are insufficient to make specific treatment and dosing recommendations, the work group noted. The researchers also noted that in-office phototherapy may not be feasible for many patients, but that in-home ultraviolet light equipment or natural sunlight in moderation could be recommended as an alternative.

The use of systemic, nonbiologic treatments for pediatric psoriasis should be “based on baseline severity of disease, subtype of psoriasis, speed of disease progression, lack of response to more conservative therapies such as topical agents and phototherapy (when appropriate), impaired physical or psychological functioning or [quality of life] due to disease extent, and the presence of comorbidities such as PsA,” the workgroup said.

Options for systemic treatment include methotrexate, cyclosporine (notably for pustular as well as plaque and erythrodermic psoriasis), and systemic retinoids. In addition, fumaric acid esters may be an option for children with moderate to severe psoriasis, with recommended clinical and laboratory monitoring.

The increasing safety and efficacy data on biologics in pediatric psoriasis patients support their consideration among first-line systemic treatments, the work group suggested. “Etanercept and ustekinumab are now [Food and Drug Administration] approved for patients with psoriasis 4 years and older and 12 years and older, respectively,” they said, and infliximab and adalimumab have been used off label in children.

The work group concluded that research and knowledge gaps about pediatric psoriasis persist and include mechanism of disease onset, development of comorbidities, and identification of ideal dosing for various treatments.

Finally, the work group emphasized the importance of collaboration between dermatologists and primary care providers for managing psoriasis in children, as well as the importance of patient education.

“Dermatologists should be mindful of the unique aspects of the emotional development of children and the social dynamics of having a visible difference,” they wrote. “Shared decision making with the patient (if age appropriate) and the caregivers is a useful approach, particularly as related to the use of off-label medications to treat severe disease,” they said.

“This is the first time that pediatric psoriasis has been discussed as an independent topic within the guideline,” said one of the guideline authors, Dawn M.R. Davis, MD, of the Mayo Clinic, Rochester, Minn., in an interview. “Children have unique physiology and psychosocial aspects to their care relative to adults. In addition, psoriasis has some clinical manifestations that are oftentimes distinctly seen in children,” she commented. “Creation of a guideline specific to children allows us to summarize the similarities and differences of disease presentation and management. It also allows an opportunity to clarify what research data (especially therapeutics) have been studied in children and their uses, safety profiles, and dosing,” she noted.

Psoriasis can be a psychosocially debilitating disease, she emphasized. “In children, for example, isolated or prominent facial involvement is common, which can be embarrassing and impact relationships.”

The take-home message for clinicians, Dr. Davis said, is to keep in mind the multisystemic nature of psoriasis. “It is not limited to the skin,” she said. “Treating a patient with psoriasis necessitates practicing whole-person care” and considering the multiple comorbidities that impact quality of life and overall health in children, as well as adults with psoriasis, she commented. “Dermatologists can empower patients and their caregivers by educating them on the multifocal, complex nature of the disease.” She added, “We have much to learn regarding psoriasis in the pediatric population. More research into therapeutics, topical and systemic, is necessary to optimize patient care.”

The guideline was based on studies published in the PubMed and MEDLINE databases from January 2011 through December 31, 2017.

Dr. Menter and Craig A. Elmets, MD, professor of dermatology, at the University of Alabama, Birmingham, were cochairs of the work group. The pediatric guideline is the latest in a multipart series of AAD-NPF guidelines on psoriasis being published this year in the Journal of the American Academy of Dermatology.

Many of the guideline authors, including lead author Dr. Menter, disclosed relationships with multiple companies; however, a minimum 51% of workgroup members had no relevant conflicts of interest in accordance with AAD policy. There was no funding source. Dr. Davis disclosed serving as an investigator for Regeneron, with no compensation.

A real-world study of secukinumab in patients with psoriasis provided safety and effectiveness results similar to clinical trial results in patients with moderate to severe psoriasis, in a report published in the Journal of the European Academy of Dermatology and Venereology.

“The safety profile of secukinumab was similar to that reported in previous clinical trials, and no new or unexpected safety signals were observed,” according to Diamant Thaci, MD, of the Comprehensive Centre of Inflammation Medicine, University of Lübeck (Germany) and coauthors. Moreover, effectiveness in those who started treatment with secukinumab at baseline, they added, “was comparable to that observed in Phase 3 trials. High levels of effectiveness were observed also in subjects who had received previous biologic therapies, although the response rates were numerically lower, as might be expected in a difficult to treat population. In addition, lower baseline PASI [Psoriasis Area and Severity Index] in patients with prior biologic treatment could also reduce the relative decrease in PASI observed over the course of the study.”

They reported on an interim analysis of the first 1,988 patients enrolled in the PROSPECT study, an observational 24-week study conducted in Germany; 1,323 patients completed the 24 week study; total cumulative exposure to secukinumab was 746.3 patient-years. Their mean baseline PASI was 17.7, slightly lower than those in typical clinical trials, and most (91%) had received systemic therapies before.

Almost half the patients (46%) experienced an adverse event during treatment, and about 4% experienced a serious adverse event; only 1% of serious adverse events were considered related to the study drug. About 7% discontinued treatment with secukinumab because of an adverse event. The most common reasons for discontinuation were lack of benefit in 2.4%, psoriasis in 2.3%, and upper respiratory tract viral infection in 0.5%.

The most common adverse events were nasopharyngitis (8.7%), pruritus (2.9%), and headache (2.4%). Rates of neoplastic disorders and major cerebrovascular events were similar to published data, with 5 patients (0.3%) experiencing a major adverse cardiovascular event and 10 (0.5%) experiencing a malignancy. Four patients (0.2%) developed inflammatory bowel disease, 42 (2.1%) developed Candida infection, 2 (0.1%) developed hepatotoxicity, and 11 (0.6%) an injection-site reaction. There were three deaths, determined not to be related to secukinumab, the authors wrote.

Efficacy was also similar to that observed in earlier studies, they noted, with positive results regardless of concomitant medication. Overall, 44% of the cohort used concomitant medications.

Of the 829 patients using concomitant topical treatments, 73% had started before baseline. In all, 110 patients were also using conventional systemic medications and phototherapy; 77 started treatment before baseline. The most commonly employed concomitant therapies were topical steroids and phototherapy.

Overall, most patients (86%) achieved a PASI 75 by week 24, with 68.5% achieving a PASI 90, and 40% achieving a PASI 100 at that time point.

Secukinumab was most effective among the 83 patients who were naive to systemic therapies; in these patients, results at week 24 were as follows: PASI 75, 93%; PASI 90, 84%; and PASI 100, 66%. Among patients who had previously received a biologic, scores were slightly lower: PASI 75, 78%; PASI 90, 55%; and PASI 100, 29%.

“These interim data from PROSPECT confirm the effectiveness and safety of secukinumab in the routine clinical setting, in a large cohort of psoriasis patients with high disease severity,” the investigators concluded.

Initially approved in the United States in 2015, secukinumab, an interleukin-17A antagonist, is indicated for treating moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy, adults with psoriatic arthritis, and adults with active ankylosing spondylitis.

The study was funded by Novartis, Germany; four authors are employees of the company. Dr. Thaci has served as an investigator and/or consultant for multiple pharmaceutical companies, including Novartis, AbbVie, Amgen, Arena, Biogen Idec, Boehringer Ingelheim, and Celgene. Other authors also disclosed serving as investigators, consultants, and/or speakers for Novartis and other companies.

In addition, lower baseline PASI [Psoriasis Area and Severity Index] in patients with prior biologic treatment could also reduce the relative decrease in PASI observed over the course of the study.”

They reported on an interim analysis of the first 1,988 patients enrolled in the PROSPECT study, an observational 24-week study conducted in Germany; 1,323 patients completed the 24 week study; total cumulative exposure to secukinumab was 746.3 patient-years. Their mean baseline PASI was 17.7, slightly lower than those in typical clinical trials, and most (91%) had received systemic therapies before.

Almost half the patients (46%) experienced an adverse event during treatment, and about 4% experienced a serious adverse event; only 1% of serious adverse events were considered related to the study drug. About 7% discontinued treatment with secukinumab because of an adverse event. The most common reasons for discontinuation were lack of benefit in 2.4%, psoriasis in 2.3%, and upper respiratory tract viral infection in 0.5%.

The most common adverse events were nasopharyngitis (8.7%), pruritus (2.9%), and headache (2.4%). Rates of neoplastic disorders and major cerebrovascular events were similar to published data, with 5 patients (0.3%) experiencing a major adverse cardiovascular event and 10 (0.5%) experiencing a malignancy. Four patients (0.2%) developed inflammatory bowel disease, 42 (2.1%) developed Candida infection, 2 (0.1%) developed hepatotoxicity, and 11 (0.6%) an injection-site reaction. There were three deaths, determined not to be related to secukinumab, the authors wrote.

Efficacy was also similar to that observed in earlier studies, they noted, with positive results regardless of concomitant medication. Overall, 44% of the cohort used concomitant medications.

Of the 829 patients using concomitant topical treatments, 73% had started before baseline. In all, 110 patients were also using conventional systemic medications and phototherapy; 77 started treatment before baseline. The most commonly employed concomitant therapies were topical steroids and phototherapy.

Overall, most patients (86%) achieved a PASI 75 by week 24, with 68.5% achieving a PASI 90, and 40% achieving a PASI 100 at that time point.

Secukinumab was most effective among the 83 patients who were naive to systemic therapies; in these patients, results at week 24 were as follows: PASI 75, 93%; PASI 90, 84%; and PASI 100, 66%. Among patients who had previously received a biologic, scores were slightly lower: PASI 75, 78%; PASI 90, 55%; and PASI 100, 29%.

“These interim data from PROSPECT confirm the effectiveness and safety of secukinumab in the routine clinical setting, in a large cohort of psoriasis patients with high disease severity,” the investigators concluded.

Initially approved in the United States in 2015, secukinumab, an interleukin-17A antagonist, is indicated for treating moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy, adults with psoriatic arthritis, and adults with active ankylosing spondylitis.

The study was funded by Novartis, Germany; four authors are employees of the company. Dr. Thaci has served as an investigator and/or consultant for multiple pharmaceutical companies, including Novartis, AbbVie, Amgen, Arena, Biogen Idec, Boehringer Ingelheim, and Celgene.

A real-world study of secukinumab in patients with psoriasis provided safety and effectiveness results similar to clinical trial results in patients with moderate to severe psoriasis, in a report published in the Journal of the European Academy of Dermatology and Venereology.

“The safety profile of secukinumab was similar to that reported in previous clinical trials, and no new or unexpected safety signals were observed,” according to Diamant Thaci, MD, of the Comprehensive Centre of Inflammation Medicine, University of Lübeck (Germany) and coauthors. Moreover, effectiveness in those who started treatment with secukinumab at baseline, they added, “was comparable to that observed in Phase 3 trials. High levels of effectiveness were observed also in subjects who had received previous biologic therapies, although the response rates were numerically lower, as might be expected in a difficult to treat population. In addition, lower baseline PASI [Psoriasis Area and Severity Index] in patients with prior biologic treatment could also reduce the relative decrease in PASI observed over the course of the study.”

Biologic-naive patients with psoriasis or psoriatic arthritis had a lower risk of serious infection with interleukin-12/23 (IL-12/23) inhibitors than they did with tumor necrosis factor (TNF) inhibitors, but this difference disappeared in patients with previous exposure to biologics, according to data from a retrospective study of nearly 10,000 adults.

Biologics, though effective, can increase the risk for serious infection in psoriatic arthritis and psoriasis patients, and comparison data on the safety of various biologics are limited, wrote Xintong Li of Johns Hopkins University, Baltimore, and colleagues.

In a study published in Annals of the Rheumatic Diseases, the researchers identified 11,560 treatment episodes for 9,305 adults during January 1, 2015, through May 1, 2018, which included 6,043 episodes of psoriasis only, 1,869 episodes of psoriatic arthritis only, and 3,648 episodes of both conditions. The average age of the patients was 46 years, and 53% were men. The investigators studied the IL-12/23 inhibitor ustekinumab (Stelara), the IL-17A inhibitors secukinumab (Cosentyx) and ixekizumab (Taltz), and TNF inhibitors adalimumab (Humira), certolizumab pegol (Cimzia), etanercept (Enbrel), golimumab (Simponi), and infliximab (Remicade). They did not study the interleukin-17 (IL-17) inhibitor brodalumab (Siliq) or IL-23 inhibitors guselkumab (Tremfya), risankizumab (Skyrizi), or tildrakizumab (Ilumya) since they were FDA approved after or toward the end of the study period.

The primary outcome of serious infection, defined as hospitalization with infection as part of the diagnostic codes, occurred in 190 cases (2% of all treatment episodes); the most common serious infections were sepsis and pneumonia.

Overall, new biologics users had similar infection risks with IL-17 and TNF inhibitors, with incidence rates per 100 person-years of 3.4 and 2.2, respectively. By contrast, the incidence rate per 100 person-years was 0.9 with IL-12/23 inhibitors. Incidence rates were similar across all three biologic types for experienced biologics users.

The researchers also grouped patients by condition, including both treatment-naive and -experienced patients. Of the 156 serious infections in psoriasis patients, 26 occurred with IL-17 inhibitors, 29 with IL-12/23 inhibitors, and 101 with TNF inhibitors. Of 105 serious infections in the psoriatic arthritis group, 14 occurred with IL-17, 13 with IL-12/23, and 78 with TNF.

After adjusting for propensity scores, researchers found no evidence of increased serious infection risk for treatment with IL-17 inhibitors, compared with IL-12/23 (hazard ratio, 1.12; 95% confidence interval, 0.62-2.03) or TNF inhibitors (HR, 0.89; 95% CI, 0.48-1.66).

The study findings were limited by several factors, including the use of ICD diagnostic codes that were not fully validated in the patient population, a short follow-up period, and inclusion of only insured patients in the United States, the researchers noted.

However, the results suggest that serious infection risk may vary between patients with psoriasis and psoriatic arthritis, and between biologic-naive and -experienced patients, and that, despite the relatively small difference in absolute effect, “this potentially clinically relevant signal for reduced infections among the IL-12/23 inhibitors warrants further investigation and surveillance efforts,” they concluded. In addition, they said, the findings might guide clinicians and patients in choosing appropriate biologics for a particular condition.

The study was supported by the Center for Drug Safety and Effectiveness at the Johns Hopkins Bloomberg School of Public Health. The researchers had no financial conflicts to disclose. Ms. Li conducted the research while she was at Johns Hopkins, but is now with the University of North Carolina, Chapel Hill.
