Psoriasis

Key clinical point: Prevalence of subclinical atherosclerosis is higher among patients with psoriasis and nonalcoholic fatty liver disease (NAFLD). Additionally, those with elevated hepatic inflammation had a higher burden of coronary atherosclerosis.

Major finding: Among patients with psoriasis, the prevalence of subclinical atherosclerosis was higher among those with vs without NAFLD (61% vs 23%; P = .006). Uptake of 2-[fluorine-18]fluoro-2-deoxy-D-glucose was significantly associated with noncalcified (β, 0.28; P < .001), fibrofatty (β, 0.49; P less than 001), and lipid-rich necrotic core (β, 0.28; P = .003) coronary burden.

Study details: Findings are from a 2-cohort cross-sectional study including 314 patients with psoriasis. The European cohort consisted of 76 patients with psoriasis and 76 control patients and the United States cohort consisted of 162 patients with psoriasis.

Disclosures: This study was funded by National Heart, Lung, and Blood Institute Intramural Research Program. Dr. Mehta, Dr. Gelfand, Dr. González-Cantero, and Dr. Prussick declared serving as a consultant and/or speaker and receiving research grants and personal fees from various sources.

Key clinical point: Compared with the general population, patients with moderate-to-severe plaque psoriasis were at an increased risk for lympho-hematological malignancies (LHM) and lymphoma, particularly cutaneous T-cell lymphoma (CTCL).

Major finding: Patients with moderate-to-severe plaque psoriasis vs general population had significantly higher risk for LHM (hazard ratio [HR], 1.55; 95% confidence interval [CI], 1.24-2.94) and lymphoma (HR, 1.27; 95% CI, 1.08-1.50). The risk for CTCL was markedly augmented in patients with psoriasis (HR, 6.22; 95% CI, 3.39-11.42).

Study details: Findings are from a meta-analysis of 25 observational studies including 2,501,652 study subjects. Most of the studies included patients with moderate-to-severe psoriasis.

Key clinical point: Use of analgesics was higher in patients with psoriasis, particularly those with concomitant psoriatic arthritis (PsA), which could be because of increased joint pain.

Major finding: Moderate-to-severe joint pain was reported by 69% vs 45% of patients with vs without PsA (P less than .0001). Patients with psoriasis vs reference individuals used more nonsteroidal anti‐inflammatory drugs (NSAIDS; 21.0% vs 17.3%) and opioids (14.2% vs 9.0%) within 1 year. Use of NSAIDS (30.8%) and opioids (22.7%) was even higher in patients with psoriasis and PsA. Of all symptoms, only joint pain seemed to be associated with the use of analgesics (P less than .05).

Study details: Findings are from a cross-sectional study of 4,016 adults with psoriasis including 847 with concomitant PsA and 3,490 reference individuals.

Key clinical point: Patients with moderate-to-severe psoriasis who were new users of infliximab and adalimumab vs etanercept had a higher risk for serious infections. The risk was lower with ustekinumab and comparable with secukinumab, ixekizumab, brodalumab, guselkumab, or apremilast vs etanercept.

Major finding: Compared with etanercept, the risk for serious infections was higher for patients who initiated adalimumab (estimated weighted hazard ratio [wHR], 1.22; 95% confidence interval [CI], 1.07-1.38) or infliximab (wHR, 1.79; 95% CI, 1.49-2.16), whereas the risk was lower with ustekinumab (wHR, 0.79; 95% CI, 0.67-0.94). The risk for serious infections was not higher for new users of secukinumab, ixekizumab, brodalumab, guselkumab, or apremilast vs etanercept.

Study details: Findings are from the analysis of a real-world cohort of 44,239 adults with psoriasis who were new users of biologic/biosimilar or targeted synthetic antipsoriatic agents and had no history of serious infection.

Bimekizumab has been approved by the European Commission for the treatment of moderate to severe plaque psoriasis in adults, according to a statement from the manufacturer.

Bimekizumab (Bimzelx), a humanized IgG1 monoclonal antibody, is the first approved treatment for moderate to severe plaque psoriasis that selectively inhibits interleukin (IL)–17A and IL-17F, the statement from UCB said.

In the United States, the Food and Drug Administration is expected to make a decision on approval of bimekizumab for treating psoriasis on Oct. 15.

Approval in the EU was based on data from three phase 3 trials including a total of 1,480 adult patients with moderate to severe psoriasis, which found that those treated with bimekizumab experienced significantly greater skin clearance, compared with placebo, ustekinumab, and adalimumab, with a favorable safety profile, according to the company.

In all three studies (BE VIVID, BE READY, and BE SURE), more than 80% of patients treated with bimekizumab showed improved skin clearance after 16 weeks, significantly more than those treated with ustekinumab, placebo, or adalimumab, based on an improvement of at least 90% in the Psoriasis Area & Severity Index (PASI 90) and an Investigator’s Global Assessment (IGA) response of clear or almost clear skin (IGA 0/1). In all three studies, these clinical responses persisted after 1 year.

The recommended dose of bimekizumab is 320 mg, given in two subcutaneous injections every 4 weeks to week 16, then every 8 weeks. However, for “some patients” weighing 120 kg or more who have not achieved complete skin clearance at 16 weeks, 320 mg every 4 weeks after that time may improve response to treatment, according to the company statement.

The most common treatment-related adverse events in the studies were upper respiratory tract infections (a majority of which were nasopharyngitis), reported by 14.5% of patients, followed by oral candidiasis, reported by 7.3%.

Results of BE READY and BE VIVID were published in The Lancet. Results of the BE SURE study were published in The New England Journal of Medicine.

Bimekizumab is contraindicated for individuals with clinically important active infections such as tuberculosis, and for individuals with any hypersensitivity to the active substance. More details on bimekizumab are available on the website of the European Medicines Agency.

Annual health care costs for patients with psoriatic arthritis rose over recent 5-year periods across all categories of resource use to a significantly greater extent than among patients with psoriasis only or those without any psoriatic disease diagnoses, according to commercial insurance claims data.

Using an IBM MarketScan Commercial Database, researchers examined claims data for 208,434 patients with psoriasis, 47,274 with PsA, and 255,708 controls who had neither psoriasis nor PsA. Controls were matched for age and sex. Those with RA, ankylosing spondylitis, Crohn’s disease, or ulcerative colitis were excluded.

The investigators examined data for 2009-2020, following patients for 5 years within that period. They looked at hospitalizations, outpatient and pharmacy services, lab services, and office visits, Steven Peterson, director of market access for rheumatology at Janssen Pharmaceuticals, said in his presentation of the data at the Pan American League of Associations for Rheumatology 2021 annual meeting, held recently as a virtual event.

The research was also published online May 2, 2021, in Clinical Rheumatology.

Big differences between the groups were seen in the first year, when the average health care costs for the PsA group were $28,322, about half of which was outpatient drug costs. That compared with $12,039 for the psoriasis group and $6,672 for the control group.

The differences tended to widen over time. By the fifth year, average costs for the PsA group were $34,290, nearly 60% of which were drug costs. That compared with $12,877 for the psoriasis group and $8,569 for the control group. In each year examined, outpatient drug costs accounted for less than half of the expenses for the psoriasis group and about a quarter for the control group.

Researchers found that the PsA group needed 28.7 prescriptions per person per year, compared with 17.0 and 12.7 in the psoriasis and control groups, respectively, Mr. Peterson said. He also noted that patients with PsA and psoriasis tended to have higher rates of hypertension, depression, and anxiety.

“The cost and resource utilization disparity between these patient groups demonstrates the high remaining unmet medical need for patients with psoriasis and psoriatic arthritis,” Mr. Peterson said during the virtual proceedings.

Do findings reflect treatment advances?

Elaine Husni, MD, MPH, director of the Arthritis and Musculoskeletal Center at the Cleveland Clinic, where she studies health outcomes in PsA, said the findings are helpful in pointing to a trend across a large sample. But she added it’s important to remember that the increasing costs could reflect recent advances in PsA treatment, which include costly biologic drugs.

“There’s a ton more treatments for psoriasis and psoriatic arthritis than there were even just 5 years ago,” she said in an interview. She was not involved in the research.

Dr. Husni would like to see a more detailed look at the costs, from the categories of expenses to the patients who are incurring the highest costs.  

“Is it just a couple of percent of really sick patients that are driving the psoriatic arthritis group?” she wondered.

She also pointed out that PsA is going to be more expensive by its very nature. PsA tends to develop 3-10 years after psoriasis, adding to the costs for someone who already has psoriasis and at a time when they are older and likely have higher health care costs because of comorbidities that develop with age.

Dr. Husni said she does think about treatment costs, in that a less expensive first-line drug might be more appropriate than going straight to a more expensive biologic, especially because they also tend to be safer. She said it’s not just a simple question of curbing costs.

“Is there a way that we can personalize medicine?” she asked. “Is there a way that we can be more accurate about which people may need the more expensive drugs, and which patients may need the less expensive drugs? Are we getting better at monitoring so we can avoid high-cost events?”

Mr. Peterson is an employee of Janssen Pharmaceuticals. Dr. Husni reported serving as a consultant to AbbVie, Amgen, Bristol-Myers Squibb, UCB, Novartis, Lilly, and Pfizer.

The differences tended to widen over time. By the fifth year, average costs for the PsA group were $34,290, nearly 60% of which were drug costs. That compared with $12,877 for the psoriasis group and $8,569 for the control group. In each year examined, outpatient drug costs accounted for less than half of the expenses for the psoriasis group and about a quarter for the control group.

Researchers found that the PsA group needed 28.7 prescriptions per person per year, compared with 17.0 and 12.7 in the psoriasis and control groups, respectively, Mr. Peterson said. He also noted that patients with PsA and psoriasis tended to have higher rates of hypertension, depression, and anxiety.

“The cost and resource utilization disparity between these patient groups demonstrates the high remaining unmet medical need for patients with psoriasis and psoriatic arthritis,” Mr. Peterson said during the virtual proceedings.

Do findings reflect treatment advances?

Elaine Husni, MD, MPH, director of the Arthritis and Musculoskeletal Center at the Cleveland Clinic, where she studies health outcomes in PsA, said the findings are helpful in pointing to a trend across a large sample. But she added it’s important to remember that the increasing costs could reflect recent advances in PsA treatment, which include costly biologic drugs.

“There’s a ton more treatments for psoriasis and psoriatic arthritis than there were even just 5 years ago,” she said in an interview. She was not involved in the research.

Dr. Husni would like to see a more detailed look at the costs, from the categories of expenses to the patients who are incurring the highest costs.  

“Is it just a couple of percent of really sick patients that are driving the psoriatic arthritis group?” she wondered.

She also pointed out that PsA is going to be more expensive by its very nature. PsA tends to develop 3-10 years after psoriasis, adding to the costs for someone who already has psoriasis and at a time when they are older and likely have higher health care costs because of comorbidities that develop with age.

Dr. Husni said she does think about treatment costs, in that a less expensive first-line drug might be more appropriate than going straight to a more expensive biologic, especially because they also tend to be safer. She said it’s not just a simple question of curbing costs.

“Is there a way that we can personalize medicine?” she asked. “Is there a way that we can be more accurate about which people may need the more expensive drugs, and which patients may need the less expensive drugs? Are we getting better at monitoring so we can avoid high-cost events?”

Mr. Peterson is an employee of Janssen Pharmaceuticals. Dr. Husni reported serving as a consultant to AbbVie, Amgen, Bristol-Myers Squibb, UCB, Novartis, Lilly, and Pfizer.

Using an IBM MarketScan Commercial Database, researchers examined claims data for 208,434 patients with psoriasis, 47,274 with PsA, and 255,708 controls who had neither psoriasis nor PsA. Controls were matched for age and sex. Those with RA, ankylosing spondylitis, Crohn’s disease, or ulcerative colitis were excluded.

The investigators examined data for 2009-2020, following patients for 5 years within that period. They looked at hospitalizations, outpatient and pharmacy services, lab services, and office visits, Steven Peterson, director of market access for rheumatology at Janssen Pharmaceuticals, said in his presentation of the data at the Pan American League of Associations for Rheumatology 2021 annual meeting, held recently as a virtual event.

Psoriasis is a chronic and relapsing systemic inflammatory disease that predisposes patients to a host of other conditions. It is believed that these widespread effects are due to chronic inflammation and cytokine activation, which affect multiple body processes and lead to the development of various comorbidities that need to be proactively managed.

In April 2019, the American Academy of Dermatology (AAD) and National Psoriasis Foundation (NPF) released recommendation guidelines for managing psoriasis in adults with an emphasis on common disease comorbidities, including psoriatic arthritis (PsA), cardiovascular disease (CVD), inflammatory bowel disease (IBD), metabolic syndrome, and mood disorders. Psychosocial wellness, mental health, and quality of life (QOL) measures in relation to psoriatic disease also were discussed.¹

The AAD-NPF guidelines address current screening, monitoring, education, and treatment recommendations for the management of psoriatic comorbidities. The Table and eTable summarize the screening recommendations. These guidelines aim to assist dermatologists with comprehensive disease management by addressing potential extracutaneous manifestations of psoriasis in adults.

Screening and Risk Assessment

Patients with psoriasis should receive a thorough history and physical examination to assess disease severity and risk for potential comorbidities. Patients with greater disease severity—as measured by body surface area (BSA) involvement and type of therapy required—have a greater risk for other disease-related comorbidities, specifically metabolic syndrome, renal disease, chronic obstructive pulmonary disease (COPD), obstructive sleep apnea, uveitis, IBD, malignancy, and increased mortality.² Because the likelihood of comorbidities is greatest with severe disease, more frequent monitoring is recommended for these patients.

Psoriatic Arthritis

Patients with psoriasis need to be evaluated for PsA at every visit. Patients presenting with signs and symptoms suspicious for PsA—joint swelling, peripheral joint involvement, and joint inflammation—warrant further evaluation and consultation. Early detection and treatment of PsA is essential for preventing unnecessary suffering and progressive joint destruction.³

There are several PsA screening questionnaires currently available, including the Psoriatic Arthritis Screening Evaluation, Psoriasis Epidemiology Screening Tool, and Toronto Psoriatic Arthritis Screen. No significant differences in sensitivity and specificity were found among these questionnaires when using the Classification Criteria for Psoriatic Arthritis as the gold standard. All 3 questionnaires—the Psoriatic Arthritis Screening Evaluation and the Psoriasis Epidemiology Screening Tool were developed for use in dermatology and rheumatology clinics, and the Toronto Psoriatic Arthritis Screen was developed for use in the primary care setting—were found to be effective in dermatology/rheumatology clinics and primary care clinics, respectively.³ False-positive results predominantly were seen in patients with degenerative joint disease or osteoarthritis. Dermatologists should conduct a thorough physical examination to distinguish PsA from degenerative joint disease. Imaging and laboratory tests to evaluate for signs of systemic inflammation (erythrocyte sedimentation rate, C-reactive protein) also can be helpful in distinguishing the 2 conditions; however, these metrics have not been shown to contribute to PsA diagnosis.¹ Full rheumatologic consultation is warranted in challenging cases.

Cardiovascular Disease

The American Heart Association and the American College of Cardiology have identified chronic inflammatory states, such as psoriasis, as inducing factors that predispose patients to CVD. Many studies have found an association among psoriasis, coronary artery disease, myocardial infarction (MI), and stroke.^4-7 It is strongly recommended that dermatologists educate patients of their increased risk for CVD, given the association between psoriasis and major adverse cardiovascular events (eg, stroke, heart failure, MI) and cardiovascular health. However, patients with congestive heart failure were found to have an increased risk of mortality associated with use of tumor necrosis factor (TNF) α inhibitors (P=.016).⁸ Thus, TNF inhibitors are contraindicated in patients with New York Heart Association Class III or Class IV congestive heart failure.⁹

Primary care physicians (PCPs) are recommended to screen patients for CVD risk factors using height, weight, blood pressure, blood glucose, hemoglobin A_1C, lipid levels, abdominal circumference, and body mass index (BMI). Lifestyle modifications such as smoking cessation, exercise, and dietary changes are encouraged to achieve and maintain a normal BMI.

Dermatologists also need to give special consideration to comorbidities when selecting medications and/or therapies for disease management. Patients on TNF inhibitors have a lower risk for MI compared with patients using topical medications, phototherapy, and other oral agents.¹⁰ Additionally, patients on TNF inhibitors have a lower risk for occurrence of major adverse cardiovascular events compared with patients treated with methotrexate or phototherapy.^11,12

Metabolic Syndrome

Numerous studies have demonstrated an association between psoriasis and metabolic syndrome. Patients with increased BSA involvement and psoriasis area and severity index scores have a higher prevalence of metabolic syndrome.¹³ Patients with psoriasis have an increased risk for the following conditions compared to controls: obesity (38% vs 31%; odds ratio [OR], 1.38; 95% CI, 1.29-1.48), elevated triglycerides (36% vs 28%; OR, 1.49; 95% CI, 1.39-1.60), hypertension (31% vs 28%; OR, 1.20; 95% CI, 1.11-12.9), and elevated glucose levels (22% vs 16%; OR, 1.44; 95% CI, 1.33-1.56).¹⁴ Dermatologists are strongly recommended to inform patients about the risk for metabolic syndrome and to encourage the measurement of blood pressure, waist circumference, fasting blood glucose, hemoglobin A_1C, and fasting lipid levels with their PCP when indicated. Body mass index and waist circumference also should be measured annually in patients with moderate to severe psoriasis because of the association with disease severity.

The association between psoriasis and weight loss has been analyzed in several studies. Weight loss, particularly in obese patients, has been shown to improve psoriasis severity, as measured by psoriasis area and severity index score and QOL measures.¹⁵ Another study found that gastric bypass was associated with a significant risk reduction in the development of psoriasis (P=.004) and the disease prognosis (P=.02 for severe psoriasis; P=.01 for PsA).¹⁶ Therefore, patients with moderate to severe psoriasis are recommended to have their obesity status determined according to national guidelines. For patients with a BMI above 40 kg/m² and standard weight-loss measures fail, bariatric surgery is recommended. Additionally, the impact of psoriasis medications on weight has been studied. Apremilast has been associated with weight loss, whereas etanercept and infliximab have been linked to weight gain.^17,18

An association between psoriasis and hypertension also has been demonstrated by studies, especially among patients with severe disease. Therefore, patients with moderate to severe psoriasis are recommended to have their blood pressure evaluated according to national guidelines, and those with a blood pressure of 140/90 mm Hg or higher should be referred to their PCP for assessment and treatment. Current evidence does not support restrictions on antihypertensive medications in patients with psoriasis. Physicians should be aware of the potential for cyclosporine to induce hypertension, which should be treated, specifically with amlodipine.¹⁹

Many studies have demonstrated an association between psoriasis and dyslipidemia, though the results are somewhat conflicting. In 2018, the American Heart Association and the American College of Cardiology deemed psoriasis as an atherosclerotic CVD risk-enhancing condition, favoring early initiation of statin therapy. Because dyslipidemia plays a prominent role in atherosclerosis and CVD, patients with moderate to severe psoriasis are recommended to undergo periodic screening with lipid tests (eg, fasting total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides).²⁰ Patients with elevated fasting triglycerides or low-density lipoprotein cholesterol should be referred to their PCP for further management. Certain psoriasis medications also have been linked to dyslipidemia. Acitretin and cyclosporine are known to adversely affect lipid levels, so patients treated with either agent should undergo routine monitoring of serum lipid levels.

Psoriasis is strongly associated with diabetes mellitus. Because of the increased risk for diabetes in patients with severe disease, regular monitoring of fasting blood glucose and/or hemoglobin A_1C levels in patients with moderate to severe psoriasis is recommended. Patients who meet criteria for prediabetes or diabetes should be referred to their PCP for further assessment and management.^21,22

Mood Disorders

Psoriasis affects QOL and can have a major impact on patients’ interpersonal relationships. Studies have shown an association between psoriasis and mood disorders, specifically depression and anxiety. Unfortunately, patients with mood disorders are less likely to seek intervention for their skin disease, which poses a tremendous treatment barrier. Dermatologists should regularly monitor patients for psychiatric symptoms so that resources and treatments can be offered.

Certain psoriasis therapies have been shown to help alleviate associated depression and anxiety. Improvements in Beck Depression Inventory and Hamilton Depression Rating Scale scores were seen with etanercept.²³ Adalimumab and ustekinumab showed improvement in Dermatology Life Quality Index compared with placebo.^24,25 Patients receiving Goeckerman treatment also had improvement in anxiety and depression scores compared with conventional therapy.²⁶ Biologic medications had the largest impact on improving depression symptoms compared with conventional systemic therapy and phototherapy.²⁷ The recommendations support use of biologics and the Goeckerman regimen for the concomitant treatment of mood disorders and psoriasis.

Renal Disease

Studies have supported an association between psoriasis and chronic kidney disease (CKD), independent of risk factors including vascular disease, hypertension, and diabetes. The prevalence of moderate to advanced CKD also has been found to be directly related to increasing BSA affected by psoriasis.²⁸ Patients should receive testing of blood urea nitrogen, creatinine, and urine microalbumin levels to assess for occult renal disease. In addition, physicians should be cautious when prescribing nephrotoxic drugs (nonsteroidal anti-inflammatory drugs and cyclosporine) and renally excreted agents (methotrexate and apremilast) because of the risk for underlying renal disease in patients with psoriasis. If newly acquired renal disease is suspected, physicians should withhold the offending agents. Patients with psoriasis with CKD are recommended to follow up with their PCP or nephrologist for evaluation and management.

Pulmonary Disease

Psoriasis also has an independent association with COPD. Patients with psoriasis have a higher likelihood of developing COPD (hazard ratio, 2.35; 95% CI, 1.42-3.89; P<.01) than controls.²⁹ The prevalence of COPD also was found to correlate with psoriasis severity. Dermatologists should educate patients about the association between smoking and psoriasis as well as advise patients to discontinue smoking to reduce their risk for developing COPD and cancer.

Patients with psoriasis also are at an increased risk for obstructive sleep apnea. Obstructive sleep apnea should be considered in patients with risk factors including snoring, obesity, hypertension, or diabetes.

Inflammatory Bowel Disease

Patients with psoriasis have an increased risk for developing IBD. The prevalence ratios of both Crohn disease (2.49) and ulcerative colitis (1.64) are increased in patients with psoriasis relative to patients without psoriasis.³⁰ Physicians need to be aware of the association between psoriasis and IBD and the effect that their coexistence may have on treatment choice for patients.

Adalimumab and infliximab are approved for the treatment of IBD, and certolizumab and ustekinumab are approved for Crohn disease. Use of TNF inhibitors in patients with IBD may cause psoriasiform lesions to develop.³¹ Nonetheless, treatment should be individualized and psoriasiform lesions treated with standard psoriasis measures. Psoriasis patients with IBD are recommended to avoid IL-17–inhibitor therapy, given its potential to worsen IBD flares.

Malignancy

Psoriasis patients aged 0 to 79 years have a greater overall risk for malignancy compared with patients without psoriasis.³² Patients with psoriasis have an increased risk for respiratory tract cancer, upper aerodigestive tract cancer, urinary tract cancer, and non-Hodgkin lymphoma.³³ A mild association exists between PsA and lymphoma, nonmelanoma skin cancer (NMSC), and lung cancer.³⁴ More severe psoriasis is associated with greater risk for lymphoma and NMSC. Dermatologists are recommended to educate patients on their risk for certain malignancies and to refer patients to specialists upon suspicion of malignancy.

Risk for malignancy has been shown to be affected by psoriasis treatments. Patients treated with UVB have reduced overall cancer rates for all age groups (hazard ratio, 0.52; P=.3), while those treated with psoralen plus UVA have an increased incidence of squamous cell carcinoma.^32,33 Adalimumab was correlated with increased risk for NMSC in patients with psoriasis but did not have an increased risk for all cancers collectively when used for various immune-mediated inflammatory diseases.³⁵ In contrast, a meta-analysis of randomized clinical trials found no association with TNF inhibitor use and NMSC.³⁶ Ustekinumab had no association with malignancy.³⁷ Treatment history should be elucidated because of higher rates of squamous cell carcinoma in patients with prior psoralen plus UVA, cyclosporine, or methotrexate use.³³ To address malignancy risk, patients with psoriasis should undergo regular screenings for skin cancer and follow national guidelines for age-appropriate cancer screenings.

Lifestyle Choices and QOL

A crucial aspect of successful psoriasis management is patient education. The strongest recommendations support lifestyle changes, such as smoking cessation and limitation of alcohol use. A tactful discussion regarding substance use, work productivity, interpersonal relationships, and sexual function can address substantial effects of psoriasis on QOL so that support and resources can be provided.

Final Thoughts

Management of psoriasis is multifaceted and involves screening, education, monitoring, and collaboration with PCPs and specialists. Regular follow-up with a dermatologist and PCP is strongly recommended for patients with psoriasis given the systemic nature of the disease. The 2019 AAD-NPF recommendations provide important information for dermatologists to coordinate care for complicated psoriasis cases, but clinical judgment is paramount when making medical decisions. The consideration of comorbidities is critical for developing a comprehensive treatment approach, and this approach will lead to better health outcomes and improved QOL for patients with psoriasis.

These guidelines aim to assist dermatologists with comprehensive disease management by addressing potential extracutaneous manifestations of psoriasis in adults.

Screening and Risk Assessment

Patients with psoriasis should receive a thorough history and physical examination to assess disease severity and risk for potential comorbidities. Patients with greater disease severity—as measured by body surface area (BSA) involvement and type of therapy required—have a greater risk for other disease-related comorbidities, specifically metabolic syndrome, renal disease, chronic obstructive pulmonary disease (COPD), obstructive sleep apnea, uveitis, IBD, malignancy, and increased mortality.² Because the likelihood of comorbidities is greatest with severe disease, more frequent monitoring is recommended for these patients.

Psoriatic Arthritis

Patients with psoriasis need to be evaluated for PsA at every visit. Patients presenting with signs and symptoms suspicious for PsA—joint swelling, peripheral joint involvement, and joint inflammation—warrant further evaluation and consultation. Early detection and treatment of PsA is essential for preventing unnecessary suffering and progressive joint destruction.³

There are several PsA screening questionnaires currently available, including the Psoriatic Arthritis Screening Evaluation, Psoriasis Epidemiology Screening Tool, and Toronto Psoriatic Arthritis Screen. No significant differences in sensitivity and specificity were found among these questionnaires when using the Classification Criteria for Psoriatic Arthritis as the gold standard. All 3 questionnaires—the Psoriatic Arthritis Screening Evaluation and the Psoriasis Epidemiology Screening Tool were developed for use in dermatology and rheumatology clinics, and the Toronto Psoriatic Arthritis Screen was developed for use in the primary care setting—were found to be effective in dermatology/rheumatology clinics and primary care clinics, respectively.³ False-positive results predominantly were seen in patients with degenerative joint disease or osteoarthritis. Dermatologists should conduct a thorough physical examination to distinguish PsA from degenerative joint disease. Imaging and laboratory tests to evaluate for signs of systemic inflammation (erythrocyte sedimentation rate, C-reactive protein) also can be helpful in distinguishing the 2 conditions; however, these metrics have not been shown to contribute to PsA diagnosis.¹ Full rheumatologic consultation is warranted in challenging cases.

Cardiovascular Disease

The American Heart Association and the American College of Cardiology have identified chronic inflammatory states, such as psoriasis, as inducing factors that predispose patients to CVD. Many studies have found an association among psoriasis, coronary artery disease, myocardial infarction (MI), and stroke.^4-7 It is strongly recommended that dermatologists educate patients of their increased risk for CVD, given the association between psoriasis and major adverse cardiovascular events (eg, stroke, heart failure, MI) and cardiovascular health. However, patients with congestive heart failure were found to have an increased risk of mortality associated with use of tumor necrosis factor (TNF) α inhibitors (P=.016).⁸ Thus, TNF inhibitors are contraindicated in patients with New York Heart Association Class III or Class IV congestive heart failure.⁹

Primary care physicians (PCPs) are recommended to screen patients for CVD risk factors using height, weight, blood pressure, blood glucose, hemoglobin A_1C, lipid levels, abdominal circumference, and body mass index (BMI). Lifestyle modifications such as smoking cessation, exercise, and dietary changes are encouraged to achieve and maintain a normal BMI.

Dermatologists also need to give special consideration to comorbidities when selecting medications and/or therapies for disease management. Patients on TNF inhibitors have a lower risk for MI compared with patients using topical medications, phototherapy, and other oral agents.¹⁰ Additionally, patients on TNF inhibitors have a lower risk for occurrence of major adverse cardiovascular events compared with patients treated with methotrexate or phototherapy.^11,12

Metabolic Syndrome

Numerous studies have demonstrated an association between psoriasis and metabolic syndrome. Patients with increased BSA involvement and psoriasis area and severity index scores have a higher prevalence of metabolic syndrome.¹³ Patients with psoriasis have an increased risk for the following conditions compared to controls: obesity (38% vs 31%; odds ratio [OR], 1.38; 95% CI, 1.29-1.48), elevated triglycerides (36% vs 28%; OR, 1.49; 95% CI, 1.39-1.60), hypertension (31% vs 28%; OR, 1.20; 95% CI, 1.11-12.9), and elevated glucose levels (22% vs 16%; OR, 1.44; 95% CI, 1.33-1.56).¹⁴ Dermatologists are strongly recommended to inform patients about the risk for metabolic syndrome and to encourage the measurement of blood pressure, waist circumference, fasting blood glucose, hemoglobin A_1C, and fasting lipid levels with their PCP when indicated. Body mass index and waist circumference also should be measured annually in patients with moderate to severe psoriasis because of the association with disease severity.

The association between psoriasis and weight loss has been analyzed in several studies. Weight loss, particularly in obese patients, has been shown to improve psoriasis severity, as measured by psoriasis area and severity index score and QOL measures.¹⁵ Another study found that gastric bypass was associated with a significant risk reduction in the development of psoriasis (P=.004) and the disease prognosis (P=.02 for severe psoriasis; P=.01 for PsA).¹⁶ Therefore, patients with moderate to severe psoriasis are recommended to have their obesity status determined according to national guidelines. For patients with a BMI above 40 kg/m² and standard weight-loss measures fail, bariatric surgery is recommended. Additionally, the impact of psoriasis medications on weight has been studied. Apremilast has been associated with weight loss, whereas etanercept and infliximab have been linked to weight gain.^17,18

An association between psoriasis and hypertension also has been demonstrated by studies, especially among patients with severe disease. Therefore, patients with moderate to severe psoriasis are recommended to have their blood pressure evaluated according to national guidelines, and those with a blood pressure of 140/90 mm Hg or higher should be referred to their PCP for assessment and treatment. Current evidence does not support restrictions on antihypertensive medications in patients with psoriasis. Physicians should be aware of the potential for cyclosporine to induce hypertension, which should be treated, specifically with amlodipine.¹⁹

Many studies have demonstrated an association between psoriasis and dyslipidemia, though the results are somewhat conflicting. In 2018, the American Heart Association and the American College of Cardiology deemed psoriasis as an atherosclerotic CVD risk-enhancing condition, favoring early initiation of statin therapy. Because dyslipidemia plays a prominent role in atherosclerosis and CVD, patients with moderate to severe psoriasis are recommended to undergo periodic screening with lipid tests (eg, fasting total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides).²⁰ Patients with elevated fasting triglycerides or low-density lipoprotein cholesterol should be referred to their PCP for further management. Certain psoriasis medications also have been linked to dyslipidemia. Acitretin and cyclosporine are known to adversely affect lipid levels, so patients treated with either agent should undergo routine monitoring of serum lipid levels.

Psoriasis is strongly associated with diabetes mellitus. Because of the increased risk for diabetes in patients with severe disease, regular monitoring of fasting blood glucose and/or hemoglobin A_1C levels in patients with moderate to severe psoriasis is recommended. Patients who meet criteria for prediabetes or diabetes should be referred to their PCP for further assessment and management.^21,22

Mood Disorders

Psoriasis affects QOL and can have a major impact on patients’ interpersonal relationships. Studies have shown an association between psoriasis and mood disorders, specifically depression and anxiety. Unfortunately, patients with mood disorders are less likely to seek intervention for their skin disease, which poses a tremendous treatment barrier. Dermatologists should regularly monitor patients for psychiatric symptoms so that resources and treatments can be offered.

Certain psoriasis therapies have been shown to help alleviate associated depression and anxiety. Improvements in Beck Depression Inventory and Hamilton Depression Rating Scale scores were seen with etanercept.²³ Adalimumab and ustekinumab showed improvement in Dermatology Life Quality Index compared with placebo.^24,25 Patients receiving Goeckerman treatment also had improvement in anxiety and depression scores compared with conventional therapy.²⁶ Biologic medications had the largest impact on improving depression symptoms compared with conventional systemic therapy and phototherapy.²⁷ The recommendations support use of biologics and the Goeckerman regimen for the concomitant treatment of mood disorders and psoriasis.

Renal Disease

Studies have supported an association between psoriasis and chronic kidney disease (CKD), independent of risk factors including vascular disease, hypertension, and diabetes. The prevalence of moderate to advanced CKD also has been found to be directly related to increasing BSA affected by psoriasis.²⁸ Patients should receive testing of blood urea nitrogen, creatinine, and urine microalbumin levels to assess for occult renal disease. In addition, physicians should be cautious when prescribing nephrotoxic drugs (nonsteroidal anti-inflammatory drugs and cyclosporine) and renally excreted agents (methotrexate and apremilast) because of the risk for underlying renal disease in patients with psoriasis. If newly acquired renal disease is suspected, physicians should withhold the offending agents. Patients with psoriasis with CKD are recommended to follow up with their PCP or nephrologist for evaluation and management.

Pulmonary Disease

Psoriasis also has an independent association with COPD. Patients with psoriasis have a higher likelihood of developing COPD (hazard ratio, 2.35; 95% CI, 1.42-3.89; P<.01) than controls.²⁹ The prevalence of COPD also was found to correlate with psoriasis severity. Dermatologists should educate patients about the association between smoking and psoriasis as well as advise patients to discontinue smoking to reduce their risk for developing COPD and cancer.

Patients with psoriasis also are at an increased risk for obstructive sleep apnea. Obstructive sleep apnea should be considered in patients with risk factors including snoring, obesity, hypertension, or diabetes.

Inflammatory Bowel Disease

Patients with psoriasis have an increased risk for developing IBD. The prevalence ratios of both Crohn disease (2.49) and ulcerative colitis (1.64) are increased in patients with psoriasis relative to patients without psoriasis.³⁰ Physicians need to be aware of the association between psoriasis and IBD and the effect that their coexistence may have on treatment choice for patients.

Adalimumab and infliximab are approved for the treatment of IBD, and certolizumab and ustekinumab are approved for Crohn disease. Use of TNF inhibitors in patients with IBD may cause psoriasiform lesions to develop.³¹ Nonetheless, treatment should be individualized and psoriasiform lesions treated with standard psoriasis measures. Psoriasis patients with IBD are recommended to avoid IL-17–inhibitor therapy, given its potential to worsen IBD flares.

Malignancy

Psoriasis patients aged 0 to 79 years have a greater overall risk for malignancy compared with patients without psoriasis.³² Patients with psoriasis have an increased risk for respiratory tract cancer, upper aerodigestive tract cancer, urinary tract cancer, and non-Hodgkin lymphoma.³³ A mild association exists between PsA and lymphoma, nonmelanoma skin cancer (NMSC), and lung cancer.³⁴ More severe psoriasis is associated with greater risk for lymphoma and NMSC. Dermatologists are recommended to educate patients on their risk for certain malignancies and to refer patients to specialists upon suspicion of malignancy.

Risk for malignancy has been shown to be affected by psoriasis treatments. Patients treated with UVB have reduced overall cancer rates for all age groups (hazard ratio, 0.52; P=.3), while those treated with psoralen plus UVA have an increased incidence of squamous cell carcinoma.^32,33 Adalimumab was correlated with increased risk for NMSC in patients with psoriasis but did not have an increased risk for all cancers collectively when used for various immune-mediated inflammatory diseases.³⁵ In contrast, a meta-analysis of randomized clinical trials found no association with TNF inhibitor use and NMSC.³⁶ Ustekinumab had no association with malignancy.³⁷ Treatment history should be elucidated because of higher rates of squamous cell carcinoma in patients with prior psoralen plus UVA, cyclosporine, or methotrexate use.³³ To address malignancy risk, patients with psoriasis should undergo regular screenings for skin cancer and follow national guidelines for age-appropriate cancer screenings.

Lifestyle Choices and QOL

A crucial aspect of successful psoriasis management is patient education. The strongest recommendations support lifestyle changes, such as smoking cessation and limitation of alcohol use. A tactful discussion regarding substance use, work productivity, interpersonal relationships, and sexual function can address substantial effects of psoriasis on QOL so that support and resources can be provided.

Final Thoughts

Management of psoriasis is multifaceted and involves screening, education, monitoring, and collaboration with PCPs and specialists. Regular follow-up with a dermatologist and PCP is strongly recommended for patients with psoriasis given the systemic nature of the disease. The 2019 AAD-NPF recommendations provide important information for dermatologists to coordinate care for complicated psoriasis cases, but clinical judgment is paramount when making medical decisions. The consideration of comorbidities is critical for developing a comprehensive treatment approach, and this approach will lead to better health outcomes and improved QOL for patients with psoriasis.

With the rise of telehealth utilization during the COVID-19 pandemic, clinical care delivery has undergone a substantial shift. This is especially true in dermatology, as utilization of telehealth has jumped from under 15% to more than 95% of dermatologists after the COVID-19 pandemic.¹ However, with this new form of care delivery, it is important to ensure that patients don’t get left behind, either due to socioeconomic/language barriers² or hesitancy about the conditions being treated.

It may not be surprising to know that the idea of using telemedicine for rheumatology is not new. Indeed, a report from 20 years ago outlined the high level of both satisfaction with live interactive telehealth visits for rheumatologic conditions and diagnostic accuracy as compared to in-person visits.³ Through guided palpation and careful history taking, it is possible to conduct a thorough visit and even manage biologics, diagnose active arthritis/enthesitis via photographs, and evaluate pain through a visual analog scale.⁴ As far as dermatology is concerned, it is clear that certain situations seem to be better suited for teledermatology, such as follow-up visits for acne/rosacea.¹ But what of psoriatic arthritis (PsA)? Does telehealth have the potential to mitigate our undertreatment of this important condition, which finds about half of patients being treated with only topical therapy or no treatment at all?⁵ Or can we modulate our visits to accommodate these patients, taking care of not only their visible psoriasis but also the underlying PsA?

Psoriasis is well suited for teledermatology management in general, especially once the diagnosis is made. Multiple studies have shown diagnostic equivalence with in-person care and even similar outcomes after treatment.^6,7 However, most studies have looked at telemedicine primarily for cutaneous psoriasis, and translating this to screening for and management of PsA is paramount. After all, a delay of only 6 months in diagnosing and treating PsA has been associated with poor outcomes.⁸ Thankfully, we do have some tools that can help. There are 3 validated screening tools for PsA: the Psoriasis Epidemiology Screening Tool (PEST), the Psoriatic Arthritis Screening and Evaluation (PASE), and the Toronto Psoriatic Arthritis Screen (ToPAS) questionnaire.⁹ Of these, the PEST seems to be a reasonable option that is quick and easily deployed; it has shown strong performance in terms of sensitivity, specificity, and negative predictive value/positive predictive value when compared to similar screening tools.¹⁰ It also should be facile to direct patients to complete the screening tool, as an online version is available on the National Psoriasis Foundation’s website (https://www.psoriasis.org/psoriatic-arthritis-screening-test/) where patients can be directed to answer 5 simple questions and report back the outcome. For treatment decisions, this tool also can be used to help identify patients who are good candidates for systemic or biologic therapy or those who should see a rheumatologist. Of course, an in-depth discussion of joint pain, morning stiffness, and tender/swollen joints may be more fruitful but also more challenging to conduct. I would propose that this can be pared down to a more direct conversation about finger pain/tenderness, tenderness at the elbow/knee (lateral epicondyle/medial femoral condyle), or heel (Achilles) as more common sites of enthesitis, and questioning about back pain or stiffness that improves with movement.⁹ By combining the screening tool with these pointed questions, even via telehealth, we can greatly improve our yield in diagnosing PsA while only adding a minute or two to our visits. I’d argue that this is much more fruitful than asking the patient to contort their bodies and camera to show an obscure lesion!

It is interesting to consider areas in dermatology where we might make a notable impact on mortality and morbidity by expanding access to care. Earlier diagnosis of melanoma, for instance, certainly would be in consideration, especially in areas of the country where access to dermatologic care is challenging. Better management of PsA has to be up there on the list of conditions where we immediately can make a tangible difference; we have the tools to do so and excellent therapeutics that are safe and effective. Our colleagues in rheumatology have embraced telemedicine with a “how, not if” approach to embracing new technology,¹¹ and it is about time that dermatology takes a similar attitude. The gap between access to dermatologic care in urban areas vs either nonmetropolitan or rural areas is increasing, and dermatology tends to be much more available in well-resourced, urban areas.¹² There are patients who need our expertise, and if it takes the compromise of adopting a technology that sometimes gives us headaches (we’ve all been on video visits with a choppy signal and inadequate lighting), we still should try to figure out the best way to do it because it’s the right thing to do for these patients. If we don’t, the determination of how to conduct teledermatology care will be taken away from us and either insurance companies or corporations not guided by dermatologists may try to enter this health care void and decide how to provide these services.

Biologics have transformed the management of moderate to severe psoriasis. There currently are 11 biologics approved by the US Food and Drug Administration (Table) for psoriasis treatment that have been affirmed by various clinical studies. This article provides dosing initiation, maintenance information, and updated clinical data using phase 3 studies (N=8) published between May 2020 and February 2021. Generic names of the 11 biologics were searched separately in the PubMed database within the specified date range. Subsequent results were reviewed by title and selected for phase 3 and 4 trials. Clinical data in this review focus on reducing patient disease burden by allocating a biologic best fit for each patient’s individual health profile.

IL-17A Inhibitors Update

Secukinumab is safe and efficacious for skin clearance in the presence of comorbidities and can be used for improving plaque psoriasis and palmoplantar pustular psoriasis. An extension of a phase 3 randomized controlled trial (RCT)—2PRECISE—evaluated the efficacy and safety of secukinumab dosing at 300 mg (n=79) and 150 mg (n=80) in adults with moderate to severe palmoplantar pustular psoriasis (palmoplantar psoriasis area and severity index [PPPASI] score ≥12 and dermatology life quality index [DLQI] ≥10) over 148 weeks.¹ Extension patients were included from the 52-week 2PRECISE study per the investigator’s judgement of a meaningful clinical response (exact criteria not described). All treatment groups demonstrated a mean (SD) PPPASI of 22.7 (9.5) by the extension trial’s start. Results affirmed that clinical response waned after week 148 in all groups excluding placebo/secukinumab 150 mg, which maintained a mean (SD) PPPASI of 22.7 (9.5). The most frequent adverse events were nasopharyngitis, pustular psoriasis, headache, and pruritus.¹

Comorbidities do not have a major impact on secukinumab’s efficacy. A post hoc analysis of 4 phase 3 RCTs—ERASURE, FIXTURE, FEATURE, and JUNCTURE—gathered data from adult patients (N=2401) to assess baseline comorbidities with efficacy and safety of secukinumab vs etanercept after 12 weeks of treatment.² Sixty-one percent (n=1469) had at least 1 comorbidity, most frequently obesity, hypertension, psoriatic arthritis, hyperlipidemia, or diabetes mellitus. All patient groups had a greater likelihood of a psoriasis area and severity index (PASI) response with any dose of secukinumab vs patients with comorbidities who were taking etanercept or placebo (P<.05) at week 12. All groups had a greater likelihood of achieving investigator global assessment scores of 0/1 (clear/almost clear) vs patients with comorbidities taking etanercept or placebo (P<.05). Baseline comorbidities did not significantly affect treatment response, except obesity, which was associated with decreased probability of achieving all PASI and investigator global assessment (P<.01) responses. Secukinumab-treated patients with and without comorbidities had equivalent likelihood of treatment-emergent adverse events (TEAEs).²

Brodalumab is an effective biologic that has shown long-term safety with continuous administration. Continuous brodalumab and brodalumab after placebo demonstrated impactful skin clearance after 120 weeks in AMAGINE-1, a phase 3 RCT involving adults (N=442) with moderate to severe plaque psoriasis.³ Patients randomized to brodalumab 210 mg (n=222) or placebo (n=220) were rerandomized according to initial treatment response. In patients switching from brodalumab to placebo at week 12, 55% and 94% achieved PASI 75 at week 20 and week 120, respectively, and 75% reached PASI 100 at week 120. Of patients with static physician global assessment (sPGA) scores of 0/1 (clear/almost clear) at week 12 who were rerandomized to brodalumab, 96% and 80% (using observed data) achieved PASI 75 and PASI 100, respectively. Mean (SD) time to return of skin disease following withdrawal of brodalumab was 74.7 (50.5) days. Treatment-emergent adverse events included headaches, arthralgia, diarrhea, and nausea. Suicidal ideation was rare (this study had 1 completed suicide), and authors cited that no causal association has been made between brodalumab and suicidality. Brodalumab also demonstrated favorable treatment response in patients who underwent a lapse in treatment, offering real-world value, as intermittent treatment administration can occur because of personal or financial reasons.³

Ixekizumab is associated with more rapid skin clearance, better resolution of nail psoriasis, and superior improvement in quality-of-life measures when compared with guselkumab. The phase 3 study IXORA-R compared skin and nail clearance as well as patient-reported outcomes over 24 weeks with ixekizumab 80 mg (n=520) vs guselkumab 100 mg (n=507) in adults with moderate to severe plaque psoriasis.⁴ Ixekizumab (50%) was shown to be no worse than guselkumab (52%; difference, –2.3%) using a noninferiority test (noninferiority margin of –11.4%). The treatments exhibited similar efficacy, with no significant difference in proportion of patients reaching PASI 100 (P=.41). Ixekizumab patients tended to have skin clearance sooner than guselkumab patients, reaching PASI 50/75/90 and PASI 100 in a median time that was 2 weeks and 7.5 weeks earlier, respectively. More ixekizumab patients (52%) achieved clear nails vs guselkumab patients (31%; P=.007). Ixekizumab patients reported greater satisfaction with their skin disease affecting quality of life (DLQI), with more DLQI 0/1 (no effect at all on patient’s life) scores and being itch free (P<.05). Ixekizumab was associated with significantly more days of complete skin clearance (PASI 100) vs guselkumab (55.6 days vs 42.2 days; P<.001). Although an upper respiratory tract infection was the most common TEAE, the proportion of TEAEs was similar between treatments.⁴

IL-23 Inhibitors Update

Tildrakizumab has similar long-term skin clearance efficacy and safety in patients with psoriasis with and without comorbid metabolic syndrome (MetS). A post hoc analysis of 2 phase 2 RCTs (reSURFACE 1/2) involving adults (N=338 and N=307) with moderate to severe plaque psoriasis assessed long-term efficacy (3 years), drug survival, and safety for 5 years of continuous tildrakizumab 100 mg and 200 mg in adults with comorbid MetS.⁵ Although no difference in efficacy was concluded, greater body mass index of the MetS population was shown to be associated with lower biologic efficacy compared to the general population. The proportion of patients who achieved PASI 75 at week 52 was comparable in patients with MetS and patients without MetS (tildrakizumab 100 mg, 85% and 86% vs 86% and 94% for reSURFACE 1/2, respectively; tildrakizumab 200 mg, 76% and 87% vs 76% and 87% for reSURFACE 1/2, respectively).⁵

Tildrakizumab also demonstrated efficacy and safety for up to 5 years in 2 other phase 3 RCTs with no dose-related differences in frequency of injections and malignancies. Tildrakizumab 100 mg is the recommended dose. The 200-mg dose can be utilized in patients with a high burden of disease and disability. reSURFACE 1 and reSURFACE 2 involved adults with chronic moderate to severe plaque psoriasis randomized to tildrakizumab 100 mg, 200 mg, or placebo with the option of long-term extension to week 244 if patients reached 50% or greater improvement from baseline PASI score.⁶ Patients in reSURFACE 2 also were randomized to etanercept 50 mg with partial responders and nonresponders at week 28 switching to tildrakizumab 200 mg until week 244. Extension results showed PASI 75 achievement in 88.7% (95% CI, 84.6%-92.1%) of patients taking tildrakizumab 100 mg (n=235), 92.5% (95% CI, 88.1%-95.7%) of patients taking tildrakizumab 200 mg (n=176), and 81.3% (95% CI, 72.6%-88.2%) of patients taking etanercept/partial nonresponders (n=85). The most common TEAE was nasopharyngitis (10.5/100 patient-years for tildrakizumab 100 mg and 10.7/100 patient-years for tildrakizumab 200 mg). The frequency of severe infections (eg, diverticulitis, pneumonia, cellulitis, appendicitis) was 1.2 per 100 patient-years for tildrakizumab 100 mg and 1.3 per 100 patient-years for tildrakizumab 200 mg.⁶

Risankizumab and tildrakizumab require the lowest number of injections, thereby providing sustainable skin clearance with a convenient injection dosing schedule for patients. Risankizumab efficacy (8.2% with inferiority margin of 12%) was noninferior to secukinumab when assessing the proportion of PASI 90 responders at week 16 (after 2 doses of risankizumab vs 7 doses of secukinumab).⁷ IMMerge, an international phase 3 RCT, involved adults (N=327) with moderate to severe plaque psoriasis to compare the safety and efficacy of risankizumab 150 mg (n=164) vs secukinumab 300 mg (n=163) up to 52 weeks. A greater proportion of the risankizumab arm (86.6%) achieved PASI 90 in 52 weeks compared to the secukinumab arm (57.1%). Superior skin clearance (PASI 90) at week 52 was achieved after 5 doses with risankizumab vs 16 doses of secukinumab. Risankizumab TEAEs were nasopharyngitis, upper respiratory tract infection, headache, arthralgia, diarrhea, and bronchitis.⁷

Continuous risankizumab treatment shows substantially stronger skin clearing performance compared with intermittent treatment following drug withdrawal, demonstrating that treatment gaps minimize therapeutic response. IMMhance, an international phase 3 RCT involving adults (N=507) with moderate to severe plaque psoriasis, evaluated the safety and efficacy with risankizumab 150 mg after 52 weeks and 104 weeks.⁸ Part A randomized patients to risankizumab 150 mg (n=407) or placebo (n=100). Part B rerandomized patients at week 28 to continue risankizumab 150 mg or placebo (designated as withdrawal of treatment; later re-treated with risankizumab 150 mg if patients had sPGA ≥3). At week 52, significantly more patients reached sPGA score of 0/1 with risankizumab/risankizumab (n=97 [87.4%]) vs risankizumab/placebo (n=138 [61.3%]; P<.001). At week 104, significantly more patients reached an sPGA score of 0/1 with risankizumab/risankizumab (n=90 [81.1%]) vs risankizumab/placebo (n=16 [7.1%]; P<.001). Risankizumab exhibited longevity following withdrawal, as median time to loss of response and relapse was 42 weeks (sPGA ≥3). The extent of TEAEs was similar between risankizumab and placebo and included nasopharyngitis, upper respiratory tract infection, headache, and back pain.⁸

Final Thoughts

Biologics for psoriasis help produce intended results for skin disease clearance and are tools for precision medicine. Recent data demonstrate safe, durable, and continuous efficacy with biologics, which offer patients a better chance of treatment success. This guide may serve as a quick reference for biologic selection with special consideration of individual disease characteristics and comorbidities.

Biologics have transformed the management of moderate to severe psoriasis. There currently are 11 biologics approved by the US Food and Drug Administration (Table) for psoriasis treatment that have been affirmed by various clinical studies. This article provides dosing initiation, maintenance information, and updated clinical data using phase 3 studies (N=8) published between May 2020 and February 2021. Generic names of the 11 biologics were searched separately in the PubMed database within the specified date range. Subsequent results were reviewed by title and selected for phase 3 and 4 trials. Clinical data in this review focus on reducing patient disease burden by allocating a biologic best fit for each patient’s individual health profile.

Secukinumab is safe and efficacious for skin clearance in the presence of comorbidities and can be used for improving plaque psoriasis and palmoplantar pustular psoriasis. An extension of a phase 3 randomized controlled trial (RCT)—2PRECISE—evaluated the efficacy and safety of secukinumab dosing at 300 mg (n=79) and 150 mg (n=80) in adults with moderate to severe palmoplantar pustular psoriasis (palmoplantar psoriasis area and severity index [PPPASI] score ≥12 and dermatology life quality index [DLQI] ≥10) over 148 weeks.¹ Extension patients were included from the 52-week 2PRECISE study per the investigator’s judgement of a meaningful clinical response (exact criteria not described). All treatment groups demonstrated a mean (SD) PPPASI of 22.7 (9.5) by the extension trial’s start. Results affirmed that clinical response waned after week 148 in all groups excluding placebo/secukinumab 150 mg, which maintained a mean (SD) PPPASI of 22.7 (9.5). The most frequent adverse events were nasopharyngitis, pustular psoriasis, headache, and pruritus.¹

Comorbidities do not have a major impact on secukinumab’s efficacy. A post hoc analysis of 4 phase 3 RCTs—ERASURE, FIXTURE, FEATURE, and JUNCTURE—gathered data from adult patients (N=2401) to assess baseline comorbidities with efficacy and safety of secukinumab vs etanercept after 12 weeks of treatment.² Sixty-one percent (n=1469) had at least 1 comorbidity, most frequently obesity, hypertension, psoriatic arthritis, hyperlipidemia, or diabetes mellitus. All patient groups had a greater likelihood of a psoriasis area and severity index (PASI) response with any dose of secukinumab vs patients with comorbidities who were taking etanercept or placebo (P<.05) at week 12. All groups had a greater likelihood of achieving investigator global assessment scores of 0/1 (clear/almost clear) vs patients with comorbidities taking etanercept or placebo (P<.05). Baseline comorbidities did not significantly affect treatment response, except obesity, which was associated with decreased probability of achieving all PASI and investigator global assessment (P<.01) responses. Secukinumab-treated patients with and without comorbidities had equivalent likelihood of treatment-emergent adverse events (TEAEs).²

Brodalumab is an effective biologic that has shown long-term safety with continuous administration. Continuous brodalumab and brodalumab after placebo demonstrated impactful skin clearance after 120 weeks in AMAGINE-1, a phase 3 RCT involving adults (N=442) with moderate to severe plaque psoriasis.³ Patients randomized to brodalumab 210 mg (n=222) or placebo (n=220) were rerandomized according to initial treatment response. In patients switching from brodalumab to placebo at week 12, 55% and 94% achieved PASI 75 at week 20 and week 120, respectively, and 75% reached PASI 100 at week 120. Of patients with static physician global assessment (sPGA) scores of 0/1 (clear/almost clear) at week 12 who were rerandomized to brodalumab, 96% and 80% (using observed data) achieved PASI 75 and PASI 100, respectively. Mean (SD) time to return of skin disease following withdrawal of brodalumab was 74.7 (50.5) days. Treatment-emergent adverse events included headaches, arthralgia, diarrhea, and nausea. Suicidal ideation was rare (this study had 1 completed suicide), and authors cited that no causal association has been made between brodalumab and suicidality. Brodalumab also demonstrated favorable treatment response in patients who underwent a lapse in treatment, offering real-world value, as intermittent treatment administration can occur because of personal or financial reasons.³

Ixekizumab is associated with more rapid skin clearance, better resolution of nail psoriasis, and superior improvement in quality-of-life measures when compared with guselkumab. The phase 3 study IXORA-R compared skin and nail clearance as well as patient-reported outcomes over 24 weeks with ixekizumab 80 mg (n=520) vs guselkumab 100 mg (n=507) in adults with moderate to severe plaque psoriasis.⁴ Ixekizumab (50%) was shown to be no worse than guselkumab (52%; difference, –2.3%) using a noninferiority test (noninferiority margin of –11.4%). The treatments exhibited similar efficacy, with no significant difference in proportion of patients reaching PASI 100 (P=.41). Ixekizumab patients tended to have skin clearance sooner than guselkumab patients, reaching PASI 50/75/90 and PASI 100 in a median time that was 2 weeks and 7.5 weeks earlier, respectively. More ixekizumab patients (52%) achieved clear nails vs guselkumab patients (31%; P=.007). Ixekizumab patients reported greater satisfaction with their skin disease affecting quality of life (DLQI), with more DLQI 0/1 (no effect at all on patient’s life) scores and being itch free (P<.05). Ixekizumab was associated with significantly more days of complete skin clearance (PASI 100) vs guselkumab (55.6 days vs 42.2 days; P<.001). Although an upper respiratory tract infection was the most common TEAE, the proportion of TEAEs was similar between treatments.⁴

IL-23 Inhibitors Update

Tildrakizumab has similar long-term skin clearance efficacy and safety in patients with psoriasis with and without comorbid metabolic syndrome (MetS). A post hoc analysis of 2 phase 2 RCTs (reSURFACE 1/2) involving adults (N=338 and N=307) with moderate to severe plaque psoriasis assessed long-term efficacy (3 years), drug survival, and safety for 5 years of continuous tildrakizumab 100 mg and 200 mg in adults with comorbid MetS.⁵ Although no difference in efficacy was concluded, greater body mass index of the MetS population was shown to be associated with lower biologic efficacy compared to the general population. The proportion of patients who achieved PASI 75 at week 52 was comparable in patients with MetS and patients without MetS (tildrakizumab 100 mg, 85% and 86% vs 86% and 94% for reSURFACE 1/2, respectively; tildrakizumab 200 mg, 76% and 87% vs 76% and 87% for reSURFACE 1/2, respectively).⁵

Tildrakizumab also demonstrated efficacy and safety for up to 5 years in 2 other phase 3 RCTs with no dose-related differences in frequency of injections and malignancies. Tildrakizumab 100 mg is the recommended dose. The 200-mg dose can be utilized in patients with a high burden of disease and disability. reSURFACE 1 and reSURFACE 2 involved adults with chronic moderate to severe plaque psoriasis randomized to tildrakizumab 100 mg, 200 mg, or placebo with the option of long-term extension to week 244 if patients reached 50% or greater improvement from baseline PASI score.⁶ Patients in reSURFACE 2 also were randomized to etanercept 50 mg with partial responders and nonresponders at week 28 switching to tildrakizumab 200 mg until week 244.
