Psoriasis

In a review of therapeutic issues for psoriasis patients who have such chronic infections as hepatitis, HIV, or latent tuberculosis infection (LTBI) or those who fall into the category of special populations (pregnant women or children), significant concerns were directly tied to the mode of action of the drugs involved.

In particular, “Most systemic agents for psoriasis are immunosuppressive, which poses a unique treatment challenge in patients with psoriasis with chronic infections because they are already immunosuppressed,” according to Shivani B. Kaushik, MD, a resident in the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York, and her colleague Mark G. Lebwohl, MD, professor and system chair of the department.

For example, the reviewers detailed a report of hepatitis B virus (HBV) and hepatitis C virus (HCV) reactivation in patients with psoriasis who were taking biologics. Virus reactivation was noted in 2/175 patients who were positive for anti-HBc antibody, 3/97 patients with HCV infection, and 8/40 patients who were positive for HBsAg (the surface antigen of HBV). From this, they concluded that “biologics pose minimal risk for viral reactivation in patients with anti-HCV or anti-HBc antibodies, but they are of considerable risk in HBsAg-positive patients.” (J Amer Acad Derm. 2019 Jan;80:43-53).

Giving a specific example, Dr. Kaushik and her colleague pointed out that the safety of ustekinumab in patients with psoriasis with concurrent HCV and HBV infection was not clear. Viral reactivation and hepatocellular cancer were reported in one of four patients with HCV and in two of seven HBsAg-positive patients; and yet, another study showed that the successful use of ustekinumab for psoriasis had no impact on liver function or viral load in a patient with coexisting HCV.

Overall, “Patients should not be treated with immunosuppressive therapies during the acute stage. However, biologic treatment can be initiated in patients with chronic or resolved hepatitis under close monitoring and collaboration with a gastroenterologist,” the researchers stated.

In addition, they pointed out that methotrexate, another commonly prescribed drug for psoriasis, is absolutely contraindicated, although the use of cyclosporine remains controversial for those patients who are HCV-antibody positive.

“Most systemic agents used in psoriasis are immunosuppressive and require appropriate screening, monitoring, and prophylaxis when used in [psoriasis] patients with chronic infections, such as hepatitis, HIV, and LTBI,” the authors concluded.

PARIS – Dermatologists are likely to do a double-take when they see the long-term efficacy and safety data for tildrakizumab (Ilumya), a high-affinity humanized monoclonal antibody targeting interleukin-23 p19, relative to the performance of older and more familiar biologic agents with other targets in psoriasis, Diamant Thaçi, MD, predicted at the annual congress of the European Academy of Dermatology and Venereology.

“The time to relapse [off tildrakizumab] is very different from what we are used to with other biologics; for example, the tumor necrosis factor inhibitors,” observed Dr. Thaçi, professor and chairman of the department of dermatology at the University of Lübeck (Germany).

He presented the 148-week, follow-up results of a pooled analysis of the open-label extension studies of reSURFACE 1 and reSURFACE 2, two pivotal phase 3 randomized double-blind international trials of 1,862 patients with moderate to severe chronic plaque psoriasis. The primary outcomes through week 12, which were instrumental in gaining marketing approval for tildrakizumab for treating psoriasis in 2018 from the Food and Drug Administration and the European Medicines Agency, have been published in the Lancet (2017 Jul 15;390[10091]:276-88).

Dr. Thaçi’s analysis of the 148-week outcomes was restricted to the patients who had at least a 75% improvement from baseline in Psoriasis Area and Severity Index scores (PASI 75) at week 28. Nearly 80% of patients on tildrakizumab reached that threshold at week 28 in reSURFACE 1, as did 73% in reSURFACE 2.

The question asked in the extension study was, How do responders to tildrakizumab at 28 weeks fare after nearly 3 years on the drug? And the answer was: very well. Maintenance of at least a PASI 75 response was observed at 148 weeks in 91% of patients on tildrakizumab at the approved 100-mg dose and 92% of those on the 200-mg dose. The FDA-approved regimen is 100 mg by subcutaneous injection at weeks 0 and 4, and then every 12 weeks after that.

An intriguing feature of reSURFACE 1 was that a subset of PASI 75 responders at week 28 got taken off tildrakizumab at that point and switched to double-blind placebo, then restarted on their earlier dose of tildrakizumab upon relapse, which was defined as loss of at least 50% of the achieved on-drug PASI improvement.

At week 64, fully 48 weeks after their last dose of tildrakizumab, the relapse rate was 54% in the group formerly on 100 mg of tildrakizumab and slightly better at 47% in those formerly on 200 mg. The median time to relapse was 226 days in the 100-mg group and 258 days in the higher-dose arm. Those are exceptionally long times to relapse, and it’s useful information to file away in the event a psoriasis patient needs to discontinue biologic therapy for a period of time, Dr. Thaçi observed.

At week 64 – again, off active treatment since week 16 – 63% of the tildrakizumab 100-mg group had lost their previous PASI 75 response, as had 52% who were formerly on tildrakizumab at 200 mg.

The long-term safety profile of tildrakizumab paralleled that of placebo. For example, the exposure-adjusted adverse event rates of serious infections and major adverse cardiovascular events were closely similar in the placebo, tildrakizumab 100 mg, and tildrakizumab 200 mg groups.

There were two notable between-group differences in adverse events of interest: injection site reactions occurred at a rate of 5.36 per 100 person-years with placebo, compared with 1.94 and 2.3 per 100 person-years with tildrakizumab at 100 and 200 mg, respectively; and the incidence of nonmelanoma skin cancer was 0.97 cases per 100 person-years in the placebo arm, versus 0.5 and 0.49 cases per 100 person-years in the two tildrakizumab arms.

Dr. Thaçi did not present PASI 90 response outcomes because, at the time the reSURFACE trials were planned, PASI 75 was considered state of the art. The PASI 90 data are still being crunched but will be available soon. The 4- and 5-year follow-up data from the long-term extension studies are also on their way.

The reSURFACE 1 and reSURFACE 2 trials and their extension studies were funded by Sun Pharma and Merck. Dr. Thaçi reported receiving research grants from and serving as a consultant and paid scientific advisor to those pharmaceutical companies and more than a dozen others.

PARIS – Two-thirds of psoriasis patients with stable low disease activity while on full-dose biologic therapy can successfully undergo biologic dose reduction with long-term maintenance of disease control and no adverse consequences, Juul van den Reek, MD, PhD, reported at the annual congress of the European Academy of Dermatology and Venereology.

She presented the results of the CONDOR trial, the first-ever formal, randomized, controlled trial of tightly regulated dose reduction of biologics, compared with usual care standard-dose therapy. “Our current advice is we think you can try to reduce the dose because there are a lot of patients who benefit from this,” declared Dr. van den Reek, a dermatologist at Radboud University, Nijmegen, the Netherlands.

The advantages of this strategy are twofold: lower expenditures for this costly collection of medications and less exposure to any long-term, drug-related health risks, she noted.

CONDOR was a Dutch six-center, 12-month, open-label, unblinded, noninferiority, randomized trial including 111 patients. Participants had to have stable low disease activity as defined by both Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) scores of 5 or less for at least 6 months while on standard-dose etanercept (Enbrel), adalimumab (Humira), or ustekinumab (Stelara) prior to enrollment. In fact, the average baseline PASI score was less than 2, with a DLQI of 0.

Participants were randomized to usual care – the customary approved dose of biologic therapy – or a drop down to 67% of that dose, achieved through prolongation of the dosing interval. If the reduced-dose patients kept their PASI and DLQI scores at 5 or less for 3 months straight, they dropped further to 50% of their original dose. However, patients who exceeded those thresholds were immediately returned to their previously effective dose.


The primary endpoint in this noninferiority trial was the difference in mean PASI scores between the dose-reduction and usual-care groups at 12 months. The prespecified margin for noninferiority was a difference of 0.5 PASI points. And that’s where the results get dicey: The mean difference turned out to be 1.1 PASI points in favor of usual care, meaning that, according to the study ground rules, dose reduction was not statistically noninferior. In hindsight, however, that 0.5-point margin was ill-considered and too narrowly defined.

“Within the chosen margins, the dose-reduction strategy seemed inferior. But what is the clinical relevance of a mean difference of 1.1 PASI points, when the accepted minimal clinically important difference is 3.2 points?” Dr. van den Reek observed.

There was no significant between-group difference in DLQI scores at 12 months. Nor did the two study arms differ in terms of the prespecified secondary endpoint of persistent disease flares as defined by a PASI or DLQI greater than 5 for 3 consecutive months: five patients in the reduced-dose group and three in the usual-care arm experienced such flares. There were no serious adverse events or other safety signals related to the intervention.

At 12 months, 50% of patients in the dose-reduction group were well maintained on 50% of their original approved-dose biologic and another 17% were doing well on 67% of their former dose.

Session chair Dedee Murrell, MD, professor of dermatology at the University of New South Wales, Sydney, noted that neither patients nor dermatologists were blinded as to treatment status in CONDOR. She then asked the question on everybody’s minds: Was there any loss of treatment efficacy when patients in the dose-reduction arm needed to resume higher-dose therapy?

No, Dr. van den Reek replied. She added that planned future CONDOR analyses include a cost-effectiveness determination as well as measurement of serum drug levels and identification of antidrug antibodies, information that might prove helpful in identifying an enriched population of patients most likely to respond favorably to biologic dose reduction. In addition, CONDOR-X, a long-term extension study, is ongoing in order to learn how patients on reduced-dose biologics fare after the 12-month mark.

The CONDOR trial was funded by the Netherlands Organization for Health Research and Development; Dr. van den Reek reported having no financial conflicts of interest.

Session chair Dedee Murrell, MD, professor of dermatology at the University of New South Wales, Sydney, noted that neither patients nor dermatologists were blinded as to treatment status in CONDOR. She then asked the question on everybody’s minds: Was there any loss of treatment efficacy when patients in the dose-reduction arm needed to resume higher-dose therapy?

No, Dr. van den Reek replied. She added that planned future CONDOR analyses include a cost-effectiveness determination as well as measurement of serum drug levels and identification of antidrug antibodies, information that might prove helpful in identifying an enriched population of patients most likely to respond favorably to biologic dose reduction. In addition, CONDOR-X, a long-term extension study, is ongoing in order to learn how patients on reduced-dose biologics fare after the 12-month mark.

The CONDOR trial was funded by the Netherlands Organization for Health Research and Development; Dr. van den Reek reported having no financial conflicts of interest.

Patients with tumor necrosis factor inhibitor–induced psoriasis could potentially be switched to a different drug class if they have moderate to severe skin eruption or mild skin eruption with an uncontrolled underlying disease such as inflammatory bowel disease, psoriasis, psoriatic arthritis, or rheumatoid arthritis, according to a new treatment algorithm proposed by researchers from Brigham and Women’s Hospital and Harvard Medical School in Boston.

The researchers outlined the prevalence of tumor necrosis factor–alpha inhibitor (TNFi)-induced psoriasis in a literature review of inflammatory bowel disease (IBD), psoriasis, psoriatic arthritis (PsA), and rheumatoid arthritis (RA) and identified an estimated rate of between 2.3% and 5% in patients with RA and between 1.6% and 2.7% in patients with IBD. Although there have been reports of TNFi-induced psoriasis in patients with psoriasis and PsA, the prevalence is unclear, they wrote in the Journal of Psoriasis and Psoriatic Arthritis.

The authors then created an algorithm to manage and treat TNFi-induced psoriasiform skin eruptions with decisions to continue therapy and “treat through” symptoms, switch to a different anti-TNF therapy, or switch to a different drug class based on severity of symptoms, whether the underlying disease is well controlled, and how patients with those underlying diseases have fared with those specific therapies or agents.

“We’ve shifted gears over the past decade, and we’ve gone from having very few agents and trying to keep patients desperately on one or two agents because we didn’t want to have to give up on them for their other comorbid disease, whether it was Crohn’s, colitis, RA, or whatever it may be,” senior author Joseph Merola, MD, director of the Center for Skin and Related Musculoskeletal Diseases at Brigham and Women’s Hospital, Boston, said in an interview. “We’re now in an area where we can have an algorithm like this, and we have so many more mechanistic options to move to.”

Dr. Merola, who is board certified in dermatology and rheumatology, said the algorithm is meant to “open a dialogue” with other specialists in different areas and raise awareness of treatments in related but separate fields. For diseases not often seen by more than one specialty, with the exception of psoriasis and PsA, he said that “the idea is to start a dialogue and increase communication between specialists.”

Dr. Merola noted that while the algorithm in many respects is meant to guide a physician in a specialty in appropriate medication decisions, at the same time he hopes that “it opens a dialogue and communication with the other specialty who tends to oversee this particular disease state or class of medicine to really work together to try to find the right drug for the right person.”

For patients with a mild skin eruption and a controlled underlying disease, the algorithm recommends a “treat through” approach by continuing anti-TNF therapy and treating psoriasis symptoms with topical steroids, ultraviolet therapy, methotrexate, cyclosporine, or acitretin, and to consider dapsone in cases of pustular psoriasis. However, the researchers noted that “treat through” studies have reported complete symptom resolution in 26%-41% of patients.

For patients with recalcitrant or worsening TNFi-induced psoriasis or patients with mild skin eruptions with an uncontrolled underlying disease, the researchers proposed considering switching to a different anti-TNF therapy, although studies have shown complete resolution of symptoms in only 5%-37% of patients.

If patients worsen from there, or if they have moderate to-severe skin eruption with uncontrolled underlying disease, they could be considered for switching to a different drug class and treated based on their underlying disease, along with treatment for psoriasis symptoms. This approach has been shown to completely resolve lesions in up to 64% of cases, they said. IBD patients could benefit from ustekinumab, vedolizumab, 6-mercaptopurine, or azathioprine as an alternative to anti-TNF therapy. Those patients with psoriasis should be considered for guselkumab, while ustekinumab, ixekizumab, secukinumab, and apremilast are effective treatments for patients with psoriasis and PsA. Patients with RA could receive treatment with tocilizumab, rituximab, abatacept, and tofacitinib, the authors wrote.

Dr. Merola reported serving as a consultant and/or investigator for Merck Research Laboratories, AbbVie, Dermavant, Eli Lilly, Novartis, Janssen, UCB, Samumed, Celgene, Sanofi Regeneron, GlaxoSmithKline, Almirall, Sun Pharma, Biogen, Pfizer, Incyte, Aclaris, and Leo Pharma.

Myth: Psoriasis Is Only a Skin Problem

Psoriasis is predominantly regarded as a skin disease because of the outward clinical presentation of the condition. However, psoriasis is a disorder of the immune system and its damage may be more than skin deep.

Psoriasis commonly presents on the skin and nails, but a growing body of evidence has suggested that psoriasis is associated with systemic comorbidities. Up to 25% of psoriasis patients develop joint inflammation, and psoriatic arthritis (PsA) may precede skin involvement. There also is a risk for cardiovascular complications. Because of the emotional distress caused by psoriasis, patients may develop psychosocial disorders. Other conditions in patients with psoriasis include diabetes mellitus, high blood pressure, Crohn disease, and the metabolic syndrome.

Results from surveys conducted by the National Psoriasis Foundation from 2003 to 2011 found that the diagnosis of psoriasis preceded PsA in the majority of patients by a mean period of 14.6 years. Patients with moderate to severe psoriasis were more likely to develop PsA than patients with mild psoriasis. Furthermore, patients with severe psoriasis were more likely to develop diabetes mellitus and cardiovascular disease.

In a Cutis editorial, Dr. Jeffrey Weinberg emphasizes that the role of the dermatologist “is to identify and educate patients with psoriasis who are at risk of systemic complications and ensure appropriate follow-up for their treatment and overall health.” An infographic created by the American Academy of Dermatology illustrates areas of the body that may be impacted by psoriasis beyond the skin; for example, patients may develop eye problems, weight gain, or mood changes. Consider distributing this infographic to patients to show how psoriasis can affect more than their skin.

CHICAGO – Overweight and obese psoriasis patients have it within their power to reduce their risk of developing psoriatic arthritis through weight loss, according to a large British longitudinal study.

Bruce Jancin/MDedge News

Of the three modifiable lifestyle factors evaluated in the study as potential risk factors for the development of psoriatic arthritis in psoriasis patients – body mass index, smoking, and alcohol intake – reduction in BMI over time was clearly the winning strategy, Neil McHugh, MD, said at the annual meeting of the American College of Rheumatology.

The message from this study of 90,189 incident cases of psoriasis identified in the U.K. Clinical Practice Research Datalink was unequivocal: “If you’re overweight and have psoriasis and you lose weight, you reduce your chance of developing a nasty form of arthritis,” said Dr. McHugh, professor of pharmacoepidemiology and a rheumatologist at the University of Bath, England.

“As psoriatic arthritis affects around 20% of people with psoriasis, weight reduction amongst those who are obese may have the potential to greatly reduce their risk of psoriatic arthritis in addition to providing additional health benefits,” he added.

Among the more than 90,000 patients diagnosed with psoriasis, 1,409 subsequently developed psoriatic arthritis, with an overall incidence rate of 2.72 cases per 1,000 person-years. Baseline BMI was strongly associated in stepwise fashion with subsequent psoriatic arthritis. Psoriasis patients with a baseline BMI of 25-29.9 kg/m² were at an adjusted 1.76-fold increased risk of later developing psoriatic arthritis, compared with psoriasis patients having a BMI of less than 25. For those with a BMI of 30-34.9 kg/m², the risk of subsequent psoriatic arthritis was increased 2.04-fold. And for those with a baseline BMI of 35 kg/m² or more, the risk was increased 2.42-fold in analyses adjusted for age, sex, psoriasis duration and severity, history of trauma, and diabetes.

In contrast, the risk of developing psoriatic arthritis wasn’t significantly different between psoriasis patients who were nonsmokers, ex-smokers, or current smokers. And while there was a significantly increased risk of developing psoriatic arthritis in psoriasis patients who were current drinkers, compared with nondrinkers, the risk in ex-drinkers and heavy drinkers was similar to that in nondrinkers, a counterintuitive finding Dr. McHugh suspects was a distortion due to small numbers.

While the observed relationship between baseline BMI and subsequent risk of psoriatic arthritis was informative, it only tells part of the story, since body weight so often changes over time. Dr. McHugh and his coinvestigators had data on change in BMI over the course of 10 years of follow-up in 15,627 psoriasis patients free of psoriatic arthritis at the time their psoriasis was diagnosed. The researchers developed a BMI risk calculator that expressed the effect of change in BMI over time on the cumulative risk of developing psoriatic arthritis.

“We were able to show that if, for instance, you started with a BMI of 25 at baseline and ended up with a BMI of 30, your risk of psoriatic arthritis goes up by 13%, whereas if you start at 30 and come down to 25, your risk decreases by 13%. And the more weight you lose, the greater you reduce your risk of developing psoriatic arthritis,” the rheumatologist explained in an interview.

Indeed, with more extreme changes in BMI over the course of a decade following diagnosis of psoriasis – for example, dropping from a baseline BMI of 36 kg/m² to 23 kg/m² – the risk of developing psoriatic arthritis fell by close to 30%.

Dr. McHugh reported having no financial conflicts regarding this study, funded by the U.K. National Institute for Health Research.

LAS VEGAS – If you’re considering adding biologics for psoriasis to your clinical practice, dermatologist Kristina C. Duffin, MD, has some advice: Don’t expect to just use one drug, focus on comorbidities, and embrace strategies to bypass the potential obstacle of prior-authorization approvals.

Here are some tips from Dr. Duffin, who spoke at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar:

• Don’t expect a one-size-fits-all medication. “There is no one, single go-to drug,” said Dr. Duffin, who is cochair of the department of dermatology at the University of Utah, Salt Lake City. “Maybe someday, we will have a biological personalized medicine marker to say this is the right drug, but for now we don’t.” More than 10 biologics are available to treat psoriasis, she said, and more are in the pipeline.
• Pay close attention to comorbidities. It’s important to “have a good grasp” of a patient’s comorbidities, which can help focus the choice of a biologic, Dr. Duffin said. She recommends starting with an anti–tumor necrosis factor (TNF) agents for patients with psoriatic arthritis. For patients with Crohn’s disease, she recommends anti-TNF (adalimumab, infliximab) and anti-interleukin–12/23 or anti-IL-23 agents (ustekinumab). Anti-TNF agents should be avoided in patients with multiple sclerosis, and anti-IL-17 agents shouldn’t be given to patients with recurrent candidiasis, she noted.
• Encourage patients to make prompt decisions. Dr. Duffin sits down with patients to discuss various biologic options, and she goes over information in handouts. She also focuses on their needs: “Are they interested in getting better fast? Do they want to be clear for their wedding in a month?” She prefers to not let patients go home to think about what they’d like to do. Instead, she advises patients to make choices while at the office visit.
• Order lab tests and be careful about vaccines. Dr. Duffin orders the following tests for all patients who are starting on biologics: CBC, comprehensive metabolic panel, hepatitis B and C, and tuberculosis. She orders HIV, Hba_1c and lipid tests, if appropriate. She prefers that patients treated with biologics avoid live vaccines. She suggests other vaccines, if indicated, such as seasonal influenza and pneumonia vaccines, and for those aged 50 years and older, herpes zoster vaccine. She urges patients to call the office if they have an infection or need surgery because they may need to discuss putting a temporary hold on the biologics.
• Understand how to navigate formularies.“Getting drugs approved for patients with Medicare is a challenge,” Dr. Duffin said. It’s helpful to understand how insurers handle specific psoriasis drugs so you can choose one that’s likely to be covered if you’re unsure which one is best. The website www.covermymeds.com allows physicians to easily check insurer formularies, free of charge, she said.
• Documentation is crucial when you’re dealing with an insurer. Document body surface area, Psoriasis Area Severity Index scores, or physician global assessment measures, she advised. An app provided by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis, is a helpful in determining these measurements, she said. Also include information about failed treatments and the rationale behind why you chose a specific treatment, she said. “If denial happens, get the details,” she said. This may turn up a clerical error on the insurer’s part that incorrectly led to a denial.
• Escalate challenges to drug denials. If the preferred treatment is denied, one option is to appeal the denial. As a resource, Dr. Duffin pointed to sample letters for appealing denials for physicians and patients on the websites for the American Academy of Dermatology and the National Psoriasis Foundation. Ask for a limited 6-month approval, she said, or have the patient write a letter to the insurer using one of the sample letter templates. Another option is to ask the insurer for a “peer-to-peer” review, she said. “Sometimes it’s really hard for insurance company folks to say no to you if you have a really good story,” she commented.
• Help your patients get financial assistance. Almost every biologic manufacturer has a patient assistance plan, which can also help with deductibles and copays, Dr. Duffin said.

Dr. Duffin discloses consulting for AbbVie, Amgen, Celgene, Janssen, Lilly, Novartis, Pfizer, and Sienna. She has received grant/contracted research support from AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Novartis, Pfizer, Sienna, Stiefel, and UCB.

LAS VEGAS – If you’re considering adding biologics for psoriasis to your clinical practice, dermatologist Kristina C. Duffin, MD, has some advice: Don’t expect to just use one drug, focus on comorbidities, and embrace strategies to bypass the potential obstacle of prior-authorization approvals.

Here are some tips from Dr. Duffin, who spoke at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar:

• Don’t expect a one-size-fits-all medication. “There is no one, single go-to drug,” said Dr. Duffin, who is cochair of the department of dermatology at the University of Utah, Salt Lake City. “Maybe someday, we will have a biological personalized medicine marker to say this is the right drug, but for now we don’t.” More than 10 biologics are available to treat psoriasis, she said, and more are in the pipeline.
• Pay close attention to comorbidities. It’s important to “have a good grasp” of a patient’s comorbidities, which can help focus the choice of a biologic, Dr. Duffin said. She recommends starting with an anti–tumor necrosis factor (TNF) agents for patients with psoriatic arthritis. For patients with Crohn’s disease, she recommends anti-TNF (adalimumab, infliximab) and anti-interleukin–12/23 or anti-IL-23 agents (ustekinumab). Anti-TNF agents should be avoided in patients with multiple sclerosis, and anti-IL-17 agents shouldn’t be given to patients with recurrent candidiasis, she noted.
• Encourage patients to make prompt decisions. Dr. Duffin sits down with patients to discuss various biologic options, and she goes over information in handouts. She also focuses on their needs: “Are they interested in getting better fast? Do they want to be clear for their wedding in a month?” She prefers to not let patients go home to think about what they’d like to do. Instead, she advises patients to make choices while at the office visit.
• Order lab tests and be careful about vaccines. Dr. Duffin orders the following tests for all patients who are starting on biologics: CBC, comprehensive metabolic panel, hepatitis B and C, and tuberculosis. She orders HIV, Hba_1c and lipid tests, if appropriate. She prefers that patients treated with biologics avoid live vaccines. She suggests other vaccines, if indicated, such as seasonal influenza and pneumonia vaccines, and for those aged 50 years and older, herpes zoster vaccine. She urges patients to call the office if they have an infection or need surgery because they may need to discuss putting a temporary hold on the biologics.
• Understand how to navigate formularies.“Getting drugs approved for patients with Medicare is a challenge,” Dr. Duffin said.

LAS VEGAS – Pay attention to comorbidities in your psoriasis patients because there may not be anyone else doing so.

“Many of our patients don’t have primary care physicians; many are untreated for psoriasis. They come to a clinical trial to get treated – some of them may not have insurance – so it is important for us to watch for these comorbidities,” Kristina C. Duffin, MD, said at Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.

Yet, that does not seem to be happening consistently, according to Dr. Duffin, of the department of dermatology at the University of Utah, Salt Lake City. One in five dermatologists admitted to never screening or referring their psoriasis patients for management of cardiovascular risks in a 2015 survey (J Am Acad Dermatol. 2015 doi: 10.1016/j.jaad.2015.07.029).

Often patients at the start of biologic therapy are counseled about the risk for developing tuberculosis, yet the lifetime risk for doing so in the United States is 0.3%. Similarly, patients are often counseled on the risk for developing lymphoma, even though the excess risk for developing lymphoma that can be attributed to psoriasis treatment is 7.9 per 100,000 psoriasis patients per year. That screening seems to be driven by warnings issued in direct-to-consumer advertising, Dr. Duffin suggested.

“Although psoriasis patients have an increased relative risk of lymphoma, the absolute risk attributable to psoriasis is low,” Dr. Duffin pointed out.

Some of the comorbidities she advised dermatologists to watch for are described below.
 

Psoriatic arthritis

Psoriatic arthritis is the most important psoriasis comorbidity, Dr. Duffin said. Between 20% and 30% of psoriasis patients will develop psoriatic arthritis.

In a study of 1,511 patients in 48 centers in Germany, 21% of psoriasis patients were diagnosed with psoriatic arthritis and of those, more than 95% had active arthritis and 53% had five or more affected joints (Br J Dermatol. 2009;160[5]:1040-7).

The GRAPPA app is an easy, free screening tool for psoriatic arthritis; patients who score 3 or more out of 5 items on the psoriasis epidemiology screening tool (PEST) are deemed positive for psoriatic arthritis, Dr. Duffin noted.
 

Cardiovascular disease

Psoriasis patients are at increased risk of myocardial infarction, stroke, cardiovascular death, diabetes, and chronic kidney disease, Dr. Duffin said. In fact, CV risk from severe psoriasis is similar to the risk conferred by diabetes.

She added that there is epidemiologic evidence for CV risk modification with several of the biologics approved for psoriasis.
 

Hypertension

Hypertension is prevalent and more severe in psoriasis patients, Dr. Duffin said, citing a 2011 case-control study of electronic medical records at the University of California, Davis. Psoriasis patients with hypertension were 5 times more likely than patients without psoriasis to be on one antihypertensive medication, 9.5 times more likely to be on two, and almost 20 times more likely to be on four antihypertensive medications (PLoS One. 2011 Mar 29;6[3]:e18227. doi: 10.1371/journal.pone.0018227).

Importantly, few primary care physicians and cardiologists are aware of the increased risk for hypertension in psoriasis patients.

Less than half (45%) of primary care physicians and 57% of cardiologists reported they were aware that psoriasis was associated with worse cardiovascular outcome, and only 43% of physicians reported screening psoriasis patients for hypertension starting at age 20 years, according to a 2012 survey of 251 physicians (J Am Acad Dermatol. 2012 Sep;67[3]:357-62).

Dr. Duffin called on dermatologists to ensure that the primary care physicians they work with understand these increased risks.

“Commit to including a comment in consultation letters or letters back to primary care physicians that talks about the cardiovascular risks of the disease,” she said.

Dr. Duffin reported that she is a consultant and has received grant or contracted research support for many companies that manufacture dermatologic therapies.

Myth: Pick Psoriasis Scales to Remove Them

Patients may be inclined to pick psoriasis scales that appear in noticeable areas or on the scalp. However, they should be counseled to avoid this practice, which could cause an infection. Instead, Dr. Steven Feldman (Winston-Salem, North Carolina) suggests putting on an ointment or oil-like medication to soften the scale. “Almost any kind of moisturizer will change the reflective properties of the scale so that you don’t see the scale,” he advised. He also suggested descaling agents such as topical salicylic acid or lactic acid. His patient education video is available on the American Academy of Dermatology website should you wish to direct your patients to it.

Because salicylic acid is a keratolytic (or peeling agent), it works by causing the outer layer of skin to shed. When applied topically, it helps to soften and lift psoriasis scales. Coal tar over-the-counter products also can be used for the same purpose. The over-the-counter product guide from the National Psoriasis Foundation is a valuable resource to share with patients.

Expert Commentary

I agree that it is very important to treat scale very gently. In addition to risk for infection, picking and traumatizing scale can lead to worsening of the psoriasis. This is known as the Koebner phenomenon. The phenomenon was first described by Heinrich Koebner in 1876 as the formation of psoriatic lesions in uninvolved skin of patients with psoriasis after cutaneous trauma. This isomorphic phenomenon is now known to involve numerous diseases, among them vitiligo, lichen planus, and Darier disease.

Over one-third of psoriasis patients have PsA

About two-thirds of patients with psoriasis in a national registry also had psoriatic arthritis (PsA) and/or psoriasis in at least one challenging-to-treat (CTT) area, and one-quarter had both, according to Kristina Callis Duffin, MD, of the University of Utah, Salt Lake City, and her associates.

Their analysis included 2,042 psoriasis patients who were enrolled in the Corrona Psoriasis Registry between April 2015 and May 2018 and initiated biologic treatment during that time. The mean age was 49.6 years, 80% of the patients were white, and 51% were obese. Mean disease duration was 19.9 years and 89.2% of the patients had moderate to severe disease. CTT areas include the scalp, nails, and palmoplantar areas.

A total of 784 people in the cohort (38.4%) had PsA, 778 (38.1%) had scalp psoriasis, 326 (16.0%) had nail psoriasis, 223 (10.9%) had palmoplantar psoriasis, and 535 (26.2%) had both PsA and psoriasis in at least two CTT areas. The most common combinations were PsA plus scalp psoriasis and PsA plus nail and scalp psoriasis.

“These results indicate a need to further characterize patients with psoriasis who have PsA and CTT areas and evaluate the impact of these factors to better understand their treatment needs,” the investigators noted.

The Corrona registry has been supported by numerous pharmaceutical companies, and the study authors reported numerous financial relationships with industry; two authors are Novartis employees.

Secukinumab effective for slowing radiographic progression in active PsA

Treatment with secukinumab significantly reduced radiographic progression in patients with active PsA, according to Désirée van der Heijde, MD, PhD, professor of rheumatology at Leiden University Medical Center, and her associates.

The results come from an analysis of the FUTURE 5 trial, a study of 996 patients with active PsA despite previous NSAID treatment, disease-modifying antirheumatic drug treatment, or anti–tumor necrosis factor (TNF) therapy. Patients were randomized to receive 300 mg subcutaneous secukinumab with loading dose, 150 mg secukinumab with loading dose, 150 mg secukinumab without loading dose, or placebo, at baseline; weeks 1, 2, 3, and 4; then every 4 weeks.

After 24 weeks, the mean change in van der Heijde–modified Total Sharp Score for PsA was 0.08 for the 300-mg secukinumab group (P less than .01), 0.17 for the 150-mg secukinumab with loading dose group (P less than .05), a reduction of 0.09 for the 150-mg secukinumab without loading dose group (P less than .01), and 0.50 for the placebo group. Lower radiographic progression was seen regardless of prior anti-TNF or concomitant methotrexate treatment.

The study was funded by Novartis. The study authors reported financial disclosures with numerous companies; five authors are Novartis employees.

Tildrakizumab sustains efficacy in plaque psoriasis treatment after 1 year

Nearly all patients receiving the interleukin-23 inhibitor tildrakizumab for the treatment of moderate to severe plaque psoriasis maintained or improved their Psoriasis Area and Severity Index (PASI) response rate after 52 weeks of treatment, compared with their response after 28 weeks.

The analysis, conducted by Boni E. Elewski, MD, of the University of Alabama at Birmingham, and her associates, included 352 patients who received 100 mg tildrakizumab and 313 who received 200 mg tildrakizumab. Treatment was received at baseline, at 4 weeks, and then every 12 weeks afterward.

At week 28, the proportions of patients achieving PASI 100, PASI 90-99, PASI 75-89, and PASI 50-74 at week 28 were 25.9%, 38.4%, 25.3%, and 10.5%, respectively, among those treated with the 100-mg dose. The proportions were 24.6%, 24.3%, 19.5%, and 31.6%, respectively, among those treated with the 200-mg dose.

In patients who achieved at least PASI 90 on either dose at week 28, 88.9%-89.4% maintained that response at week 52. For patients with PASI 75-89, 39.3%-40.4% maintained that response and 33.7%-41.0% achieved a PASI 90 response. At week 52, in patients with PASI 50-74, 20.2%-29.7% achieved at least a PASI 90, 52.5%-64.9% achieved PASI 75, and only 2.6% of patients on either dose had fallen below PASI 50.

Four study authors reported being clinical investigators on studies sponsored by Merck and Sun Pharmaceuticals; five authors are employees of Sun Pharmaceuticals.
 

Halobetasol/tazarotene combination most effective for plaque psoriasis treatment

A fixed combination of halobetasol propionate 0.01% and tazarotene 0.045% lotion provided a synergistic effect over either component on its own for the treatment of plaque psoriasis, according to Leon H. Kircik, MD, of Indiana University, Indianapolis, and his associates.

The investigators performed a post hoc analysis of 212 patients with moderate to severe plaque psoriasis randomized to receive either the halobetasol/tazarotene combination, halobetasol only, tazarotene only, or vehicle only for 8 weeks, with follow-up at 12 weeks. Treatment success was based on the proportion of patients who achieved at least a 2-grade improvement in the Investigator Global Assessment (IGA) score, IGA scores of “clear” or “almost clear,” and percent change from baseline in IGA multiplied by Body Surface Area (BSA) composite score (IGAxBSA). “Synergy was calculated by summing up the contribution of the individual active ingredients (HP and TAZ) to overall efficacy and comparing to the efficacy achieved with HP/TAZ lotion relative to vehicle,” the authors explained.

Relative to vehicle, treatment success for halobetasol/tazarotene after 8 weeks was 42.8%, 23.6% for halobetasol alone, and 9.0% for tazarotene alone. After 12 weeks, the difference was 31.3%, 14.1%, and 5.9%, respectively. The percent change in IGAxBSA scores from baseline after 8 weeks, relative to vehicle, were 51.6%, 37.3%, and 3.3%, respectively. After 12 weeks, the change was 47.3%, 25.7%, and 8.6%, respectively.

After 8 weeks, the synergy ratio for treatment success and IGAxBSA scores for the halobetasol/tazarotene combination was 1.3. After 12 weeks, the synergy ratio for treatment success was 1.6 and the ratio for IGAxBSA scores was 1.4.

“By combining two agents into one once-daily formulation, this novel formulation reduces the number of product applications and may help patient adherence,” the study authors noted.

Brodalumab demonstrates low immunogenicity in moderate to severe psoriasis

The immunogenicity of brodalumab in patients with moderate to severe plaque psoriasis was low and did not compromise the efficacy or safety profile of the drug, according to Kristian Reich, MD, of Dermatologikum Berlin and SCIderm Research Institute in Hamburg, Germany, and his associates.

Data from a 12-week, phase 2 trial with a 352-week, open-label extension and three 52-week phase 3 trials were included in the analysis. Antidrug antibodies (ADAs) were tested, and positive samples were further analyzed for neutralizing ADAs by a cell-based assay.

Out of the 4,461 patients who received brodalumab, 122 (2.7%) were positive for ADAs after starting brodalumab. The incidence rate ranged from 1.9% to 3.4% between all dosing groups (140 mg, 210 mg, variable dosing, and 210 mg of brodalumab after ustekinumab). In 58 (1.4%) of patients, ADAs were transient. No patients had neutralizing ADAs, and no evidence of altered pharmacokinetics, loss of efficacy, or changes in the safety profile of brodalumab in subjects positive for ADAs was seen.

No significant difference was seen in the incidence rate of hypersensitivity or injection site reactions in brodalumab, compared with placebo or ustekinumab. The most common injection site reactions were injection site pain, erythema, and bruising.

The study was supported by Amgen. The study authors reported numerous disclosures. Two authors are employees of Leo Pharma, one author is a former employee of the company.
 

Secukinumab improves patient-reported outcomes in CTT psoriasis

Treatment with secukinumab significantly improved patient-reported outcomes such as fatigue, itch, pain, and quality of life measures in patients with CTT psoriasis after 6 months, according to Jerry Bagel, MD, of the Psoriasis Treatment Center of Central New Jersey, East Windsor, and his associates.

A total of 68 patients with psoriasis localized to at least one CTT area who were enrolled in the Corrona Psoriasis Registry from April 15, 2015, through May 10, 2018, and were receiving secukinumab for the entirety of the 6-month study period were included in the analysis. Patient-reported outcomes included in the analysis were fatigue, itch, pain, Dermatology Quality of Life Index (DLQI) score, and Work Productivity and Activity Impairment (WPAI) scale.

The mean age at enrollment was 51.2 years and almost 80% of patients were white. Mean psoriasis duration was 21.8 years and nearly half had PsA.

Visual analog scale scores improved over baseline for fatigue (mean, 23.2 vs. 33.2; P = .01), itch (20.9 vs. 49.6; P less than .0001), and pain (12.1 vs. 33.8; P less than .0001). DLQI scores also improved (2.9 vs. 8.1; P less than .0001), and the proportion of patients who reported that psoriasis had at least a moderate effect on their life was reduced after 6 months (22.1% vs. 59.7%; P less than .0001).

Based on WPAI results, patients experienced significant improvements in the percentage of daily activities impaired (mean, 9.5% vs 17.5%; P = .0075); of the 42 patients who were employed, both impairment percentage (3.7% vs. 11.2%; P = .0148) and percentage of work hours affected (4.9% vs. 11.9%; P = .0486) were reduced from baseline.

“These results are consistent with previous reports from secukinumab clinical trials; however, additional real-world studies are needed to evaluate the long-term effectiveness of secukinumab for improving [patient-reported outcomes] in patients with psoriasis in CTT areas,” the authors noted.

The Corrona registry has been supported by numerous pharmaceutical companies, and several study authors reported various disclosures with industry. Two authors are Novartis employees. The study was supported by Novartis; the company participated in the interpretation of data and review and approval of the abstract.

Over one-third of psoriasis patients have PsA

About two-thirds of patients with psoriasis in a national registry also had psoriatic arthritis (PsA) and/or psoriasis in at least one challenging-to-treat (CTT) area, and one-quarter had both, according to Kristina Callis Duffin, MD, of the University of Utah, Salt Lake City, and her associates.

Their analysis included 2,042 psoriasis patients who were enrolled in the Corrona Psoriasis Registry between April 2015 and May 2018 and initiated biologic treatment during that time. The mean age was 49.6 years, 80% of the patients were white, and 51% were obese. Mean disease duration was 19.9 years and 89.2% of the patients had moderate to severe disease. CTT areas include the scalp, nails, and palmoplantar areas.

A total of 784 people in the cohort (38.4%) had PsA, 778 (38.1%) had scalp psoriasis, 326 (16.0%) had nail psoriasis, 223 (10.9%) had palmoplantar psoriasis, and 535 (26.2%) had both PsA and psoriasis in at least two CTT areas. The most common combinations were PsA plus scalp psoriasis and PsA plus nail and scalp psoriasis.

“These results indicate a need to further characterize patients with psoriasis who have PsA and CTT areas and evaluate the impact of these factors to better understand their treatment needs,” the investigators noted.

The Corrona registry has been supported by numerous pharmaceutical companies, and the study authors reported numerous financial relationships with industry; two authors are Novartis employees.

Secukinumab effective for slowing radiographic progression in active PsA

Treatment with secukinumab significantly reduced radiographic progression in patients with active PsA, according to Désirée van der Heijde, MD, PhD, professor of rheumatology at Leiden University Medical Center, and her associates.

The results come from an analysis of the FUTURE 5 trial, a study of 996 patients with active PsA despite previous NSAID treatment, disease-modifying antirheumatic drug treatment, or anti–tumor necrosis factor (TNF) therapy. Patients were randomized to receive 300 mg subcutaneous secukinumab with loading dose, 150 mg secukinumab with loading dose, 150 mg secukinumab without loading dose, or placebo, at baseline; weeks 1, 2, 3, and 4; then every 4 weeks.

After 24 weeks, the mean change in van der Heijde–modified Total Sharp Score for PsA was 0.08 for the 300-mg secukinumab group (P less than .01), 0.17 for the 150-mg secukinumab with loading dose group (P less than .05), a reduction of 0.09 for the 150-mg secukinumab without loading dose group (P less than .01), and 0.50 for the placebo group. Lower radiographic progression was seen regardless of prior anti-TNF or concomitant methotrexate treatment.

The study was funded by Novartis. The study authors reported financial disclosures with numerous companies; five authors are Novartis employees.

Tildrakizumab sustains efficacy in plaque psoriasis treatment after 1 year

Nearly all patients receiving the interleukin-23 inhibitor tildrakizumab for the treatment of moderate to severe plaque psoriasis maintained or improved their Psoriasis Area and Severity Index (PASI) response rate after 52 weeks of treatment, compared with their response after 28 weeks.

The analysis, conducted by Boni E. Elewski, MD, of the University of Alabama at Birmingham, and her associates, included 352 patients who received 100 mg tildrakizumab and 313 who received 200 mg tildrakizumab. Treatment was received at baseline, at 4 weeks, and then every 12 weeks afterward.

At week 28, the proportions of patients achieving PASI 100, PASI 90-99, PASI 75-89, and PASI 50-74 at week 28 were 25.9%, 38.4%, 25.3%, and 10.5%, respectively, among those treated with the 100-mg dose. The proportions were 24.6%, 24.3%, 19.5%, and 31.6%, respectively, among those treated with the 200-mg dose.

In patients who achieved at least PASI 90 on either dose at week 28, 88.9%-89.4% maintained that response at week 52. For patients with PASI 75-89, 39.3%-40.4% maintained that response and 33.7%-41.0% achieved a PASI 90 response. At week 52, in patients with PASI 50-74, 20.2%-29.7% achieved at least a PASI 90, 52.5%-64.9% achieved PASI 75, and only 2.6% of patients on either dose had fallen below PASI 50.
