Psoriasis

Patients with psoriasis or psoriatic arthritis who started ustekinumab (Stelara) versus a tumor necrosis factor inhibitor had no differences in the overall risks of incident atrial fibrillation (AFib) or major adverse cardiovascular events (MACE), according to authors of a retrospective cohort study of two commercial insurance databases.

Subgroup analyses in the study also revealed “no statistically significant heterogeneity” in risk of AFib or MACE by age, sex, or presence of diabetes, Moa P. Lee, PharmD, of Brigham and Women’s Hospital and Harvard Medical School, Boston, and her coauthors reported in JAMA Dermatology.

These findings provide additional evidence on cardiovascular risks with ustekinumab versus other treatments.

The findings are consistent with previous observations of a small but nonsignificant increase in cardiovascular disease among patients with psoriatic disease and provide new insight into the risk of AFib with psoriatic treatments with the two therapies, Dr. Lee and her colleagues wrote.

The retrospective study of two U.S. commercial health care claims databases included 60,028 adult patients with psoriasis or psoriatic arthritis who initiated therapy with ustekinumab (n = 9,071) or a tumor necrosis factor (TNF) inhibitor (n = 50,957), including adalimumab, certolizumab pegol, golimumab, etanercept, or infliximab. The investigators excluded any patient with an AFib diagnosis at baseline and those receiving any antiarrhythmic or anticoagulant treatment.

The incidence of AFib was 5.0 and 4.1 per 1,000 person-years in the ustekinumab and TNF inhibitor groups, respectively, with an adjusted hazard ratio of 1.08 (95% CI, 0.76-1.54). The incidence of MACE (a composite endpoint of MI, stroke, and coronary revascularization) was 6.2 and 6.1 per 1,000 person-years in the ustekinumab and TNF inhibitor groups, with an adjusted hazard ratio of 1.10 (95% CI, 0.80-1.52).

In subgroup analyses, the adjusted HR for AFib with ustekinumab versus TNF inhibitor was 1.46 (95% CI, 0.98-2.18) for patients aged 60 years and older and 1.47 (95% CI, 0.93-2.31) in patients with diabetes, the investigators wrote.

The adjusted HR for AFib with ustekinumab versus TNF inhibitors was 1.21 in men (95% CI, 0.87-1.69) and 0.82 in women (95% CI, 0.49-1.39), while for MACE, the HRs were 1.31 in men (95% CI, 0.97-1.76) and 0.91 in women (95% CI, 0.56-1.47).

“Although the risk of these cardiovascular outcomes appeared to be similar across the subpopulations included in our study, further investigations on potentially modifying treatment effects stratified by important risk factors may be warranted,” Dr. Lee and her coauthors wrote.

The study was supported by the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital. Several authors reported financial relationships with pharmaceutical companies marketing biologics for psoriasis and psoriatic arthritis.

There is no apparent association between proinflammatory foods and increased risk of incident psoriasis, psoriatic arthritis, or atopic dermatitis, reported Alanna C. Bridgman of Queen’s University, Kingston, Ont., and her associates.

In a large, retrospective cohort study among women from the Nurses’ Health Study II (NHS-II), including 85,185 psoriasis participants and 63,443 atopic dermatitis participants, Ms. Bridgman and her associates sought to determine whether proinflammatory diet increased the risk of incident psoriasis, psoriatic arthritis, or atopic dermatitis. Clinicians administered food frequency questionnaires every 4 years beginning in 1991 among female nurses aged 25-42 years.

Food groups included in the evaluation were those most predictive of three plasma markers of inflammation: interleukin-6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor–alpha R2 (TNF-R2). Proinflammatory foods included processed meat, red meat, organ meat, white fish, vegetables other than leafy green and dark yellow, refined grains, low- and high-energy drinks, and tomatoes. Anti-inflammatory foods included beer, wine, tea, coffee, dark yellow and green leafy vegetables, snacks such as popcorn and crackers, fruit juice, and pizza.

No association was found between proinflammatory diet and increased likelihood for incident psoriasis, psoriatic arthritis, or atopic dermatitis. Although proinflammatory dietary patterns were associated with psoriatic arthritis in the age-adjusted model, the hazard ratio was attenuated and found to be no longer statistically significant after adjustment for important confounders such as body mass index. In addition, no significant relationship between atopic dermatitis and proinflammatory diet was observed, they reported. The study was published in the Journal of the American Academy of Dermatology.

Ms. Bridgman and her associates measured dietary patterns using the Empirical Dietary Inflammatory Pattern (EDIP); dietary patterns measuring high on the EDIP scale were associated with higher levels of TNF-alpha, TNF-alpha R1, TNF-alpha R2, CRP, IL-6, and adiponectin. Psoriasis and psoriatic arthritis are Th1- and Th17-mediated diseases that exhibit higher serum levels of IL-6, CRP, and TNF-alpha, unlike atopic dermatitis, which is primarily a Th2-mediated condition featuring reduced involvement of the Th1/Th17 inflammatory cytokines.

Because a goal of the EDIP score was to “account for the overall effect of dietary patterns,” the researchers included in their analysis only those food groups that “explain the maximal variation in the three noted inflammatory biomarkers.”

All patients included in the study were questioned at baseline regarding their height and race/ethnicity. Weight, smoking status, and physical activity, and diagnoses of hypercholesterolemia, type 2 diabetes, cardiovascular disease, and asthma were monitored biennially.

Overall, patients with higher EDIP scores were found to have higher BMI, lower physical activity, and alcohol use, as well as increased rates of hypercholesterolemia and hypertension.

“Though we found no convincing evidence for an association with EDIP score for any of the investigated diseases, the results followed an internal pattern consistent with our hypotheses that higher EDIP scores would have more of an association with psoriatic disease than with atopic dermatitis,” the researchers wrote.

Citing recent evidence gathered in studies, such as the French NutriNet-Santé study, which demonstrated proinflammatory effects similar to those measured with the EDIP in cases where there was low adherence to the Mediterranean diet, the authors attributed their contradictory findings to “important methodological differences.” Unlike the NutriNet-Santé study, which classified psoriasis by severity, Ms. Bridgman and her colleagues examined the overall risk of incident psoriasis. “It is possible that a dietary index associated with more Th-2 inflammation would yield different results,” they noted.

The large sample size, prospectively collected dietary, and psoriatic disease data, as well as the ability to adjust for important confounding factors, were included among the strengths of the study.

That the participants were limited to U.S. women could be considered a limitation because the results may not be generalizable to other populations. The results also may not be relevant to child-onset disease because the patient population included only cases of adult-onset atopic dermatitis. Questionnaire-based diagnoses increase the likelihood of misclassification, so “dilution of the case pool with false-positive cases would bias our results towards the null,” they added.

Ultimately, the authors noted that proinflammatory diet may be associated with other health risks, but these do not warrant counseling patients concerning their possible impact in cases of psoriatic disease or atopic dermatitis.

The study was funded by Brown University department of dermatology and from Regeneron, Sanofi, the National Institutes of Health, and the National Cancer Institute. Two coauthors, one of whom has a patent pending for the nix-tix tick remover, disclosed ties with various companies.

WASHINGTON – Psoriasis induced by tumor necrosis factor (TNF) therapy is among the treatment-associated effects that involve the skin in patients with inflammatory bowel disease (IBD), Sophia Delano, MD, said during a session on the cutaneous effects of IBD at the annual meeting of the American Academy of Dermatology.

This is a paradoxical reaction, which can happen “weeks to years after starting a TNF blocker,” with about 70% of cases occurring during the first year of therapy, said Dr. Delano, an attending physician in the dermatology program at Boston Children’s Hospital.

Those receiving infliximab are more likely to develop TNF inhibitor–induced psoriasis, compared with those on adalimumab or etanercept. TNF inhibitor–induced psoriasis may not track with gastrointestinal activity, and some patients whose gastrointestinal disease is responding to treatment can begin to develop psoriasis, she noted.

The clinical presentation of TNF inhibitor–induced psoriasis can also vary. In one study of 216 cases, 26.9% of patients had a mixed morphology, with the most common presentations including plaque psoriasis (44.8%) and palmoplantar pustular psoriasis (36.3%). Other presentations were psoriasiform dermatitis (19.9%), scalp involvement with alopecia (7.5%), and generalized pustular psoriasis (10.9%). Locations affected were the soles of the feet (45.8%), extremities (45.4%), palms (44.9%), scalp (36.1%), and trunk (32.4%), Dr. Delano said.


TNF inhibitor–induced psoriasis is likely a class effect, she said, noting that, in the same review, symptoms resolved in 47.7% of patients who discontinued TNF inhibitors, in 36.7% of patients who switched to another TNF inhibitor, and in 32.9% of patients who continued their original therapy (J Am Acad Dermatol. 2017 Feb;76[2]:334-41). In the study, Crohn’s disease and RA were the most common diseases, in 40.7% and 37.0% of the patients, respectively.

There have been case reports of TNF antagonist–induced lupus-like syndrome (TAILS), which is more common in patients with RA and ulcerative colitis. TAILS occurs more often in women than in men; can present similarly to systemic lupus erythematosus, subacute cutaneous lupus erythematosus, and chronic cutaneous lupus; and resolves by stopping TNF inhibitor treatment, Dr. Delano said.

Skin cancer risk, infections, and injection site reactions

Both adult and pediatric patients treated with TNF inhibitors for IBD may be at increased risk for lymphoma, visceral tumors, melanoma, and nonmelanoma skin cancers. Dr. Delano referred to a study published in 2014, which identified 972 reports of melanoma in the Food and Drug Administration’s Adverse Event Reporting System database associated with TNF inhibitor use; of these, 69 cases involved patients using more than one TNF inhibitor. Infliximab, golimumab, etanercept, and adalimumab were associated with a safety signal for melanoma, but not certolizumab (Br J Dermatol. 2014 May;170[5]:1170-2).

Dr. Delano observed that thiopurines such as azathioprine are also associated with an increased cancer risk, as noted in one retrospective study that found that the risk of nonmelanoma skin cancer was 2.1 times higher in a mostly white male cohort with ulcerative colitis during treatment with thiopurines, compared with patients not treated with thiopurines (Am J Gastroenterol. 2014 Nov;109[11]:1781-93). A greater duration of treatment (more than 6 months) and higher doses were associated with higher risks.

Adalimumab, golimumab, and certolizumab can also cause injection site reactions, typically within 1- 2 days of injection, said Dr. Delano. In these cases, symptoms of erythema, warmth, burning, or pruritus are worse at the beginning of treatment and can be relieved by rotating the injection site as well as providing cool compresses, topical steroids, antihistamines, and supportive care.

“If you have a patient with a worsening reaction, consider it may represent the type 1 IgE-related hypersensitivity requiring desensitization to continue that systemic,” she noted.

Cutaneous bacterial, fungal, and viral infections such as molluscum contagiosum, verruca vulgaris, herpes simplex, and varicella zoster can occur as a result of TNF inhibition as well, and can be difficult to clear because of immunosuppression, she added.

Dr. Delano reported no relevant conflicts of interest.

In one study of 216 cases, 26.9% of patients had a mixed morphology, with the most common presentations including plaque psoriasis (44.8%) and palmoplantar pustular psoriasis (36.3%). Other presentations were psoriasiform dermatitis (19.9%), scalp involvement with alopecia (7.5%), and generalized pustular psoriasis (10.9%). Locations affected were the soles of the feet (45.8%), extremities (45.4%), palms (44.9%), scalp (36.1%), and trunk (32.4%), Dr. Delano said.


TNF inhibitor–induced psoriasis is likely a class effect, she said, noting that, in the same review, symptoms resolved in 47.7% of patients who discontinued TNF inhibitors, in 36.7% of patients who switched to another TNF inhibitor, and in 32.9% of patients who continued their original therapy (J Am Acad Dermatol. 2017 Feb;76[2]:334-41). In the study, Crohn’s disease and RA were the most common diseases, in 40.7% and 37.0% of the patients, respectively.

There have been case reports of TNF antagonist–induced lupus-like syndrome (TAILS), which is more common in patients with RA and ulcerative colitis. TAILS occurs more often in women than in men; can present similarly to systemic lupus erythematosus, subacute cutaneous lupus erythematosus, and chronic cutaneous lupus; and resolves by stopping TNF inhibitor treatment, Dr. Delano said.

Skin cancer risk, infections, and injection site reactions

Both adult and pediatric patients treated with TNF inhibitors for IBD may be at increased risk for lymphoma, visceral tumors, melanoma, and nonmelanoma skin cancers. Dr. Delano referred to a study published in 2014, which identified 972 reports of melanoma in the Food and Drug Administration’s Adverse Event Reporting System database associated with TNF inhibitor use; of these, 69 cases involved patients using more than one TNF inhibitor. Infliximab, golimumab, etanercept, and adalimumab were associated with a safety signal for melanoma, but not certolizumab (Br J Dermatol. 2014 May;170[5]:1170-2).

Dr. Delano observed that thiopurines such as azathioprine are also associated with an increased cancer risk, as noted in one retrospective study that found that the risk of nonmelanoma skin cancer was 2.1 times higher in a mostly white male cohort with ulcerative colitis during treatment with thiopurines, compared with patients not treated with thiopurines (Am J Gastroenterol. 2014 Nov;109[11]:1781-93). A greater duration of treatment (more than 6 months) and higher doses were associated with higher risks.

Adalimumab, golimumab, and certolizumab can also cause injection site reactions, typically within 1- 2 days of injection, said Dr. Delano. In these cases, symptoms of erythema, warmth, burning, or pruritus are worse at the beginning of treatment and can be relieved by rotating the injection site as well as providing cool compresses, topical steroids, antihistamines, and supportive care.

“If you have a patient with a worsening reaction, consider it may represent the type 1 IgE-related hypersensitivity requiring desensitization to continue that systemic,” she noted.

Cutaneous bacterial, fungal, and viral infections such as molluscum contagiosum, verruca vulgaris, herpes simplex, and varicella zoster can occur as a result of TNF inhibition as well, and can be difficult to clear because of immunosuppression, she added.

Dr. Delano reported no relevant conflicts of interest.

All individuals with psoriasis or psoriatic arthritis aged over 50 years should receive the recombinant herpes zoster vaccine, according to a systematic review and consensus recommendations from the National Psoriasis Foundation.

Emily Baumrin, MD, of Brigham and Women’s Hospital, Boston, and her coauthors reviewed 41 studies of herpes zoster in people with psoriasis or psoriatic arthritis according to treatment modality. Their report is in the Journal of the American Academy of Dermatology.

Overall, psoriasis was associated with an increased rate of herpes zoster when compared with the general population: 13.3 cases per 1,000 patient-years for psoriasis and 15.9 for psoriatic arthritis, compared with 8.5 in healthy controls after adjustment for age, sex, and systemic medications. Most of this increased incidence was seen in patients with more severe disease: Those with mild disease who were not receiving systemic therapy had a risk similar to that of healthy controls.

However, one study suggested much of the increased risk of herpes zoster in psoriasis was accounted for by immunosuppressive therapy; when those patients were excluded, there was an 8% increase in risk.


The authors found that people whose psoriasis was treated with tofacitinib (Xeljanz) had a two- to threefold increased risk of herpes zoster, compared with those treated with tumor necrosis factor (TNF) inhibitors or conventional synthetic disease-modifying antirheumatic drugs (DMARDs).

Corticosteroids – either alone or in combination with DMARDs – were also associated with significant increases in the risk of herpes zoster. Patients treated with TNF inhibitor monotherapy had a risk of herpes zoster similar to that of those treated with conventional synthetic DMARDs or no synthetic therapy.

On the question of immunization, the authors pointed to guidelines recommending use of the live attenuated zoster vaccine (Zostavax) in immunocompetent patients or those on low-dose immunosuppression, although they noted that the vaccine is currently contraindicated for patients on biologic DMARDs.

They also examined the evidence for the use of the recently-released non-live recombinant herpes zoster vaccine (Shingrix) in immunocompromised patients, which found no evidence of vaccine-related serious adverse events in individuals with HIV and low CD4 cell counts and in autologous hematopoietic stem cell transplant recipients.

Given this, they recommended that the recombinant vaccine be administered to all patients aged over 50 years with psoriasis or psoriatic arthritis, and to those aged under 50 years who were being treated with tofacitinib, systemic corticosteroids, or combination systemic therapy.

There were insufficient data to draw conclusions about the impact of treatment with the interleukin-12/23 blocker ustekinumab (Stelara) on herpes zoster risk, but the authors noted that there was a trend toward an increased risk. They found no increase in the risk of herpes zoster with interleukin-17 inhibitors (ixekizumab [Taltz], secukinumab [Cosentyx], and brodalumab [Siliq]) and interleukin-23 (p19 subunit) inhibitors (guselkumab [Tremfya], tildrakizumab [Ilumya], and risankizumab) but noted an absence of long-term safety data for these drugs.

Four authors declared advisory, consultancy, or speaker positions with the pharmaceutical sector.

WASHINGTON – At the annual meeting of the American Academy of Dermatology, colleagues A. Yasmine Kirkorian, MD, a pediatric dermatologist at George Washington University, Washington, and interim chief of pediatric dermatology at Children’s National Health System, and Adam Friedman, MD, professor and interim chair of dermatology at the university, sat down with Dermatology News and discussed their presentations at a session on the use of immunomodulators for inflammatory and neoplastic skin diseases.

In this video, Dr. Kirkorian provides the highlights of her presentation on immunomodulators for pediatric skin diseases, with her clinical pearls and practical considerations for treating atopic dermatitis, psoriasis, and hidradenitis suppurativa in pediatric patients, covering both on- and off-label treatments.

“Children sometimes require systemic treatment and we shouldn’t hold it back from them because of their age; if they’re severely ill ... they need to be treated,” she said, summing up one of her main points.

During the interview immediately after the AAD meeting, she mentioned dupilumab, which was approved by the Food and Drug Administration for treatment of moderate to severe AD in patients aged 12-17 years.

Dr. Friedman and Dr. Kirkorian reported having no financial disclosures.

The Food and Drug Administration has approved Tremfya (guselkumab) One-Press, a single-dose, patient-controlled injector, for the treatment of moderate to severe plaque psoriasis in adults, the manufacturer announced.

FDA approval is based on results from the phase 3, multicenter, randomized ORION trial, according to a press release issued by Janssen. In a Self-Injection Assessment Questionnaire, patients who received the One-Press injection rated their satisfaction with self-injection a mean score of 9.18 (0 indicated least satisfaction, 10 indicated highest satisfaction) and rated ease of use at 9.24 (10 indicated “very easy”).

In addition, 81% of patients who received One-Press achieved a Investigator’s Global Assessment score of 0 or 1, and 76% achieved a Psoriasis Area Severity Index (PASI) 90 response after 16 weeks; no patients who received the placebo achieved either.

The most common adverse event during the ORION study was injection-site reaction; the most common adverse events associated with guselkumab, an interleukin-23 blocker, include upper respiratory infections, headache, injection-site reactions, joint pain, diarrhea, gastroenteritis, fungal skin infections, and herpes simplex infections.

WAIKOLOA, HAWAII – The highly selective interleukin-17A subunit inhibitor ixekizumab maintained a high rate of skin clearance in psoriasis patients, with no safety surprises through 3 years of prospective follow-up in the long-term extension phase of the randomized, controlled UNCOVER-3 (NCT01646177) trial, Craig L. Leonardi, MD, reported at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation.

However, the strict inclusion and exclusion criteria employed in randomized trials such as this raise questions about the broader applicability of the results in real-world clinical practice. So separately at the Hawaii seminar, Dr. Leonardi presented a single-center retrospective observational cohort study of the rapidity and duration of response to ixekizumab in his own clinical practice after the biologic received Food and Drug Administration marketing approval. Those results, too, were impressive and, in his view, highly generalizable.

“It is expected that this study cohort is generally representative of patients who are routinely seen at dermatology referral practices in the U.S.,” commented Dr. Leonardi, of Saint Louis University.

UNCOVER-3 included 1,346 psoriasis patients initially randomized 2:2:2:1 to double-blind subcutaneous ixekizumab (Taltz) at 80 mg either every 2 weeks or every 4 weeks after a 160-mg loading dose; subcutaneous etanercept at 50 mg twice weekly; or placebo for 12 weeks, followed by a switch to ixekizumab at 80 mg every 4 weeks from week 12 out to 3 years. The long-term efficacy analysis was restricted to patients who received the biologic according to what ultimately became the approved dosing schedule: a 160-mg loading dose, followed by 80 mg every 2 weeks through week 12, then 80 mg every 4 weeks. The safety analysis, in contrast, included everybody.

Dr. Leonardi presented the efficacy data using several different statistical methodologies, thereby providing an instructive lesson regarding the importance of examining the fine print when viewing clinical trial results. At one extreme is the as-observed analysis. Under this methodology, if a patient dropped out of UNCOVER-3 at, for example, week 11, the last measurement of treatment response, recorded at week 8, is carried forward by investigators and assumed to be valid for the rest of the study. Since week 8 may have been the last time the patient was doing well on the drug, the as-observed analysis can create a distorted overly favorable picture of the drug’s performance.

Real-world performance

Dr. Leonard’s analysis of ixekizumab’s performance in his own practice included 106 patients placed on the drug following its FDA approval in March 2016, 74% of whom were still on the drug 12 months later. The cohort had a mean disease duration of 15 years. Three-quarters of them had previously received biologic therapy for their psoriasis, most often a tumor necrosis factor inhibitor. The study efficacy endpoints were the sPGA and Dermatology Life Quality Index (DLQI).

Already at 1 month, 30% of ixekizumab-treated patients had an sPGA score of 0, meaning their skin was totally clear. Another 29% had an sPGA of 1, meaning almost clear. At 3 months, 53% of patients had an sPGA of 0 and 21% had an sPGA of 1. Among patients on treatment at 12 months, the rates were 39% and 24% for sPGAs of 0 and 1, respectively. And in patients with an sPGA of 0/1 at 3 months, 73% maintained that score at 12 months, including 47% with an sPGA of 0.

A DLQI score of 0/1, indicative of little or no disease effect upon a patient’s life, was present in 63% of ixekizumab-treated patients at 1 month, 84% at 3 months, and 73% at 12 months.
 

The value in pushing for PASI 100

The ixekizumab experience in the phase-3 UNCOVER clinical trial program provided the first-ever evidence that incrementally improving psoriasis also provides stepwise improvement in DLQI, a key patient-reported outcome. At week 12 under double-blind conditions, only 4% of ixekizumab-treated patients with less than a PASI 50 response had a DLQI of 0/1. The rate rose to 18.8% in those with a PASI 50 to less than PASI 75 response. In patients with a week-12 PASI 75 to less than PASI 90 response, the DLQI 0/1 rate climbed to 52.3%. At a PASI 90 to less than PASI 100 response, the rate was 66.9%. And 82.9% of patients with a PASI 100 had a DLQI of 0/1. Every step of the way, those DLQI rates were significantly different from each other.

These data are “fascinating,” Dr. Leonardi commented. “If you ever get any inquiries from the friendly insurance carrier and they want to know if you’re improving your patient’s life, this is the kind of data that supports that they’re being improved dramatically.”

Dr. Leonardi noted that ixekizumab isn’t unique in its high rate of clinical effectiveness. That distinction is shared by the other approved IL-17 inhibitors, secukinumab (Cosentyx) and brodalumab (Siliq), as well as the IL-23 inhibitor guselkumab (Tremfya). He refers to these biologics collectively as “high-performance skin-clearance drugs.” He has calculated the number needed to treat (NNT) to achieve a PASI 100 response – complete clearance of the disease – based upon clinical trial data filed with the FDA and/or in the package inserts. The numbers are eye-opening: an NTT of 2.6 for ixekizumab based upon data from the UNCOVER-2 trial, 2.4 for brodalumab, 2.7 for guselkumab, and 3.6 for secukinumab. To help put that into perspective, the NNTs for methotrexate and etanercept (Enbrel) – not so long ago considered state of the art medications for moderate to severe psoriasis – are 25 and 23.3, respectively.

The UNCOVER trial portfolio and Dr. Leonardi’s single-center retrospective study were funded by Eli Lilly, which markets ixekizumab. He reported serving as a consultant to and receiving research funding from that company and more than a dozen others.

Leonardi, MD, reported at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation.

However, the strict inclusion and exclusion criteria employed in randomized trials such as this raise questions about the broader applicability of the results in real-world clinical practice. So separately at the Hawaii seminar, Dr. Leonardi presented a single-center retrospective observational cohort study of the rapidity and duration of response to ixekizumab in his own clinical practice after the biologic received Food and Drug Administration marketing approval. Those results, too, were impressive and, in his view, highly generalizable.

“It is expected that this study cohort is generally representative of patients who are routinely seen at dermatology referral practices in the U.S.,” commented Dr. Leonardi, of Saint Louis University.

UNCOVER-3 included 1,346 psoriasis patients initially randomized 2:2:2:1 to double-blind subcutaneous ixekizumab (Taltz) at 80 mg either every 2 weeks or every 4 weeks after a 160-mg loading dose; subcutaneous etanercept at 50 mg twice weekly; or placebo for 12 weeks, followed by a switch to ixekizumab at 80 mg every 4 weeks from week 12 out to 3 years. The long-term efficacy analysis was restricted to patients who received the biologic according to what ultimately became the approved dosing schedule: a 160-mg loading dose, followed by 80 mg every 2 weeks through week 12, then 80 mg every 4 weeks. The safety analysis, in contrast, included everybody.

Dr. Leonardi presented the efficacy data using several different statistical methodologies, thereby providing an instructive lesson regarding the importance of examining the fine print when viewing clinical trial results. At one extreme is the as-observed analysis. Under this methodology, if a patient dropped out of UNCOVER-3 at, for example, week 11, the last measurement of treatment response, recorded at week 8, is carried forward by investigators and assumed to be valid for the rest of the study. Since week 8 may have been the last time the patient was doing well on the drug, the as-observed analysis can create a distorted overly favorable picture of the drug’s performance.

Real-world performance

Dr. Leonard’s analysis of ixekizumab’s performance in his own practice included 106 patients placed on the drug following its FDA approval in March 2016, 74% of whom were still on the drug 12 months later. The cohort had a mean disease duration of 15 years. Three-quarters of them had previously received biologic therapy for their psoriasis, most often a tumor necrosis factor inhibitor. The study efficacy endpoints were the sPGA and Dermatology Life Quality Index (DLQI).

Already at 1 month, 30% of ixekizumab-treated patients had an sPGA score of 0, meaning their skin was totally clear. Another 29% had an sPGA of 1, meaning almost clear. At 3 months, 53% of patients had an sPGA of 0 and 21% had an sPGA of 1. Among patients on treatment at 12 months, the rates were 39% and 24% for sPGAs of 0 and 1, respectively. And in patients with an sPGA of 0/1 at 3 months, 73% maintained that score at 12 months, including 47% with an sPGA of 0.

A DLQI score of 0/1, indicative of little or no disease effect upon a patient’s life, was present in 63% of ixekizumab-treated patients at 1 month, 84% at 3 months, and 73% at 12 months.
 

The value in pushing for PASI 100

The ixekizumab experience in the phase-3 UNCOVER clinical trial program provided the first-ever evidence that incrementally improving psoriasis also provides stepwise improvement in DLQI, a key patient-reported outcome. At week 12 under double-blind conditions, only 4% of ixekizumab-treated patients with less than a PASI 50 response had a DLQI of 0/1. The rate rose to 18.8% in those with a PASI 50 to less than PASI 75 response. In patients with a week-12 PASI 75 to less than PASI 90 response, the DLQI 0/1 rate climbed to 52.3%. At a PASI 90 to less than PASI 100 response, the rate was 66.9%. And 82.9% of patients with a PASI 100 had a DLQI of 0/1. Every step of the way, those DLQI rates were significantly different from each other.

These data are “fascinating,” Dr. Leonardi commented. “If you ever get any inquiries from the friendly insurance carrier and they want to know if you’re improving your patient’s life, this is the kind of data that supports that they’re being improved dramatically.”

Dr. Leonardi noted that ixekizumab isn’t unique in its high rate of clinical effectiveness. That distinction is shared by the other approved IL-17 inhibitors, secukinumab (Cosentyx) and brodalumab (Siliq), as well as the IL-23 inhibitor guselkumab (Tremfya). He refers to these biologics collectively as “high-performance skin-clearance drugs.” He has calculated the number needed to treat (NNT) to achieve a PASI 100 response – complete clearance of the disease – based upon clinical trial data filed with the FDA and/or in the package inserts. The numbers are eye-opening: an NTT of 2.6 for ixekizumab based upon data from the UNCOVER-2 trial, 2.4 for brodalumab, 2.7 for guselkumab, and 3.6 for secukinumab. To help put that into perspective, the NNTs for methotrexate and etanercept (Enbrel) – not so long ago considered state of the art medications for moderate to severe psoriasis – are 25 and 23.3, respectively.

The UNCOVER trial portfolio and Dr. Leonardi’s single-center retrospective study were funded by Eli Lilly, which markets ixekizumab. He reported serving as a consultant to and receiving research funding from that company and more than a dozen others.

The American Academy of Dermatology and the National Psoriasis Foundation have jointly released two new guidelines on the management and treatment of psoriasis with a focus on biologics and comorbidities.

These guidelines are the first of two papers to be published in the Journal of the American Academy of Dermatology (JAAD), with four more guidelines on psoriasis to be published later this year in JAAD on phototherapy, topical therapy, nonbiologic systemic medications, and treatment of pediatric patients.

The guideline on biologics updates the 2008 AAD guidelines on psoriasis. In an interview, Alan Menter, MD, cochair of the guidelines work group and lead author of the biologics paper, said the guidelines for biologics were needed because of major advances with the availability of new biologics over the last decade. For example, three tumor necrosis factor–alpha (TNF-alpha) inhibitors were available in 2008, but that number has increased to 10 biologics and now includes agents such as those targeting interleukin (IL)-12/IL-23, IL-17 and IL-23.

In addition, the new guidelines from AAD were developed to represent improvements in the management of patients with moderate to severe psoriasis as well as the relationship between psoriasis and related comorbidities.

“Major advances in new biologic drugs [are] now available to patients, plus [there have been] significant advances in our understanding of comorbid conditions,” such as cardiovascular comorbidities, said Dr. Menter, chairman of the division of dermatology, Baylor University Medical Center, and clinical professor of dermatology, University of Texas, both in Dallas.

The working group for each set of guidelines consisted of dermatologists, patient representatives, a cardiologist, and a rheumatologist. The biologic guidelines working group analyzed studies published between January 2008 and December 2018 and issued a series of recommendations based on published evidence for the effectiveness, adverse events, and switching for Food and Drug Administration–approved TNF-alpha inhibitors (etanercept, infliximab, adalimumab, certolizumab, and TNF-alpha biosimilars); IL-12/IL-23 inhibitors (ustekinumab); IL-17 inhibitors (secukinumab, ixekizumab, and brodalumab); and IL-23 inhibitors (guselkumab and tildrakizumab, and risankizumab, which is still under FDA review) for monotherapy or combination therapy in patients with moderate to severe psoriasis.

“Both the comorbidities guidelines and the biologic guidelines will help educate the psoriasis population with input from dermatologists in clinical practices,” Dr. Menter said.

However, both working groups noted there are still significant gaps in research, such as the effects of treatment combinations for new biologics and the lack of biomarkers that would identify which biologics are best suited for individual psoriasis patients.

There is also little known about the complex relationship between psoriasis and its comorbidities, and how psoriasis treatment can potentially prevent future disease. To ensure treatment of psoriasis-related comorbidities, dermatologists should consider psoriasis as a systemic disease with multiple comorbidities and interact with primary care doctors, cardiologists, and other providers involved in the care of the patients, Dr. Menter said.

There were no specific funding sources reported for the guidelines. Several authors reported relationships with industry, including pharmaceutical companies with drugs and products involving psoriasis, during the development of the guidelines. If a potential conflict was noted, the working group member recused himself or herself from discussion and drafting of recommendations, according to the paper. Dr. Menter’s disclosure includes serving as a consultant, speaker, investigator, and adviser, and receiving honoraria, from multiple pharmaceutical companies.

Increased competition when new tumor necrosis factor inhibitors entered the market did not translate into price reductions during 2009-2016, according to a new analysis of Medicare claims data and wholesale acquisition costs published online in JAMA Internal Medicine.

A research team led by Alvaro San-Juan-Rodriguez, PharmD, of the University of Pittsburgh said their analysis illustrates “a market failure contributing to the rising costs of prescription drugs.”

Before 2009, etanercept (Enbrel), infliximab (Remicade), and adalimumab (Humira) were the only tumor necrosis factor (TNF) inhibitors approved by the Food and Drug Administration for treating rheumatoid arthritis; infliximab and adalimumab are also approved to treat inflammatory bowel disease. In 2009, subcutaneous golimumab (Simponi) and certolizumab pegol (Cimzia) entered the market, followed by intravenous golimumab (Simponi ARIA) in 2013.

The researchers used an interrupted time series analysis with a linear model that “regressed the annual cost of existing TNF inhibitors against a continuous variable for month, two indicator variables for each period after market entry of new drugs, and the interactions between them.”

Using estimates from this model, the researchers calculated the trends in costs that would have been expected if new anti-TNFs had not entered the market. They examined costs for TNF inhibitors typically reimbursed under Medicare Part D (Enbrel, Humira, Simponi, and Cimzia) and adjusted the data for increases in manufacturer rebates, but “owing to lack of data,” they could not “assess how purchasing prices for drugs typically reimbursed under Medicare Part B [Remicade and Simponi ARIA] changed over time.” All estimates for annual costs of treatment were based on dosing recommendations for a standard 80-kg patient with rheumatoid arthritis.

The annual treatment costs with existing TNF inhibitors increased after the three new agents entered the market. For example, when wholesale acquisition cost data was applied, annual treatment costs with existing TNF inhibitors increased by 144% from April 2009 to December 2016 after new drug entry (from $15.809 to $38,574). However, in the absence of new drugs’ entry, the researchers estimated that annual treatment costs would have increased by 34% (from $15,809 to $21,184).

Medicare annual treatment costs increased by 139% (from $14,901 to $35,613), compared with a 43% increase expected in the absence of new drugs’ entry (from $14,901 to $21,308). Medicare spending increased in parallel with increases in annual treatment costs, but out-of-pocket costs and manufacturer coverage gap discounts remained relatively constant over time.

The research team noted that if cost trends had not changed after the entry of new products, the costs of Enbrel, Remicade, and Humira in December 2016 would have been 40%-45% lower.

“These increases were born solely by Medicare, while patient out-of-pocket spending remained flat. In addition, these increases were not offset by manufacturer discounts in the Medicare Part D coverage gap. The rising costs of existing products may reflect manufacturers’ opportunism in response to payers’ increased willingness to pay for TNF inhibitors after market entry of new, more expensive agents,” the research team noted.

The study was funded in part by the Myers Family Foundation and one author reported funding from the National Heart, Lung, and Blood Institute.
