Psoriasis

SAN FRANCISCO – It might be time to add psoriasis to the list of comorbidities bariatric surgery is likely to help.

New York University investigators have found a marked improvement in psoriasis and psoriatic arthritis following bariatric surgery, especially with severe disease. The more weight people lose, the better they do.

In an interview at the annual meeting of the American College of Rheumatology, investigator Dr. Soumya Reddy, codirector of NYU’s Psoriatic Arthritis Center in Manhattan, explained how the findings can be used in the clinic and their potential impact on bariatric surgery authorization.

Stroke risk was 50% higher in the month after patients with autoimmune diseases developed herpes zoster, compared with the next 2-6 years, according to Dr. Leonard H. Calabrese.

“These data provide urgency for developing strategies to reduce the risk of varicella zoster virus in vulnerable immunosuppressed patients,” said Dr. Calabrese of the department of rheumatic and immunologic diseases at the Cleveland Clinic.

Immunosuppressive therapies increase the frequency and complexity of herpes zoster, which is a known risk factor for stroke. To examine the temporal relationship between herpes zoster and stroke among immunosuppressed patients, Dr. Calabrese and his associates studied Medicare data for almost 51,000 patients with new-onset herpes zoster who also had physician-diagnosed ankylosing spondylitis, inflammatory bowel disease, psoriasis, psoriatic arthritis, or rheumatoid arthritis. The researchers excluded patients with a history of stroke.

In the multivariable analysis, stroke was 1.5 times more likely during the 6 months immediately after herpes zoster than in the 2-6 years after herpes zoster (95% confidence interval, 1.06-2.12). During this 6-month window, there were 9.8 strokes per 1,000 person-years, compared with 8.7 per 1,000 person-years in the 2-6 years after herpes zoster. Stroke risk also remained somewhat elevated during the entire year after herpes zoster (incidence rate ratio, 1.3; 95% CI, 1.05-1.61).

In general, stroke was more likely to occur among patients who were older, were receiving high-dose glucocorticoids, or had diabetes, hypertension, atrial fibrillation, or a history of transient ischemic attack, he said at the annual meeting of the American College of Rheumatology in San Francisco.

Dr. Calabrese disclosed relationships with Bristol-Myers Squibb, Crescendo, AbbVie, Genentech, Biogen, Pfizer, Sanofi-Aventis Pharmaceutical, and Johnson & Johnson. Two coauthors also disclosed relationships with several pharmaceutical companies. The other four coinvestigators had no disclosures.

Protection against shingles appeared to wane between the fifth and sixth years after patients with autoimmune diseases received the live herpes zoster vaccine, according to a large retrospective cohort study presented at the annual meeting of the American College of Rheumatology.

In contrast, shingles risk remained fairly constant among unvaccinated patients, reported Dr. Huifeng Yun, assistant professor of epidemiology at the University of Alabama, Birmingham. Based on the findings, clinicians could consider revaccinating patients with autoimmune diseases about 5 years after their first live herpes zoster vaccine, she said.*

The long-term Shingles Prevention Study recently showed that the live herpes zoster vaccine is effective for about a decade among healthy older individuals, but the duration of protection for patients with autoimmune diseases was unclear, the investigators said. Therefore, they retrospectively studied Medicare data for more than 130,000 such patients between 2006 and 2012. About one-third of patients were vaccinated against herpes zoster, and 47% had rheumatoid arthritis, 32% had psoriasis, 21% had inflammatory bowel disease, 5% had psoriatic arthritis, and 1% had ankylosing spondylitis.

Rates of herpes zoster among vaccinated patients rose from 0.75 per 100 person-years during the first year after vaccination to 1.36 during the sixth year. In the adjusted analysis, vaccinated patients had about half the risk of herpes zoster, compared with unvaccinated patients, during year 1 (relative risk, 0.52; 95% confidence interval, 0.45-0.61) and remained substantially less likely to develop shingles until year 6, when the gap in risk between vaccinated and unvaccinated patients essentially closed (RR, 0.92; 95% CI, 0.45-1.86). There was no overall change in risk among unvaccinated patients during the study period, the investigators noted.

Dr. Yun disclosed a financial relationship with Amgen. The senior author and two coauthors also disclosed relationships with several pharmaceutical companies. Two investigators had no disclosures.

LOS ANGELES – A provocative study opens the door for psoriasis and psoriatic arthritis to be added to the growing list of benefits following bariatric surgery.

“Although the natural history of psoriasis and psoriatic arthritis is typically chronic, the majority of patients experience improvement after bariatric surgery, Dr. Monica Sethi of New York University said at Obesity Week 2015.

Patrice Wendling/Frontline Medical News

At an average of 6 years after bariatric surgery, 55% of patients with psoriasis and 62% of those with psoriatic arthritis (PsA) reported subjective lessening of their disease.

Preoperative disease severity ratings on a 10-point scale significantly decreased at the most recent follow-up for psoriasis (5.6 vs. 3.3; P less than .01) and PsA (6.4 vs. 3.9; P = .02).

“Our results indicate an association between excess weight loss and symptomatic improvement in severe cases of psoriasis, and a possible improvement in psoriatic arthritis,” she said.

Although the effects of surgical weight loss on psoriasis and PsA are unknown, obesity is known to be more prevalent among patients with psoriasis and PsA. This correlation appears to be related to fat tissue–driven systemic inflammation, Dr. Sethi said.

The investigators surveyed 128 patients with a preoperative diagnosis of psoriasis identified from a single-center database of 9,073 bariatric surgeries performed between 2002 and 2013. A total of 86 patients completed the study, with 21 patients also having a preoperative diagnosis of PsA. Their mean preoperative weight was 288 pounds and preoperative body mass index 45.8 kg/m². The average duration of psoriasis and PsA at the time of surgery was significant at 18.7 years, Dr. Sethi noted.

The mean time from surgery was 6.1 years, with a mean excess weight loss of 46.2% and total weight loss of 23.8%. Laparoscopic adjustable gastric banding was the most common surgery (91%), followed by Roux-en-Y bypass (7%).

In secondary analyses, a higher percent of excess weight loss at recent follow-up was significantly associated with an easing of psoriasis severity (59.5% vs. 43.5%; P = .046), while higher percent of excess weight loss at 1 year was associated with a trend in PsA improvement (55.4% vs. 43.8%; P = .47), Dr. Sethi said.

Easing of disease severity after surgery was associated with a higher rating of disease at the time of surgery (8.9 vs. 7.4; P less than .01) and older age at diagnosis (36.9 years vs. 25.9 years; P = .02), suggesting that these factors may be used to identify patients with a greater likelihood of improvement.

“Larger prospective studies are needed to further define the true effect of surgical weight loss on psoriasis and psoriatic arthritis,” she said at the meeting, presented by the Obesity Society and the American Society for Metabolic and Bariatric Surgery (ASMBS).

Session comoderator Dr. Peter T. Hallowell of the University of Virginia, Charlottesville, agreed that further studies are needed, but said the interesting thing is how bariatric surgery improves multiple problems.

“The results are pretty impressive with the moderate weight loss they got with laparoscopic gastric banding,” he said in an interview. “With gastric bypass or a sleeve, where we would expect greater weight loss and greater decrease in the inflammatory mediators, we may see an even greater improved outcome.”

A larger prospective study is being planned between New York University’s psoriasis and bariatric centers in about 60 patients with psoriasis and PsA undergoing bariatric surgery, mostly sleeve gastrectomy and gastric bypass, Dr. Sethi said in an interview.

COPENHAGEN – Ixekizumab showed no hint of an increased malignancy risk of any sort in 4,208 patients with moderate to severe psoriasis who had 6,480 patient-years of exposure to the investigational interleukin-17A inhibitor in seven clinical trials.

“Patients were studied for an average of 18 months on ixekizumab. You may say that’s not enough time to assess the true risk for malignancy, and I would say you’re probably right. But 18 months isn’t shabby. From such an exposure, we can get some sense of the malignancy risk with this drug,” Dr. Bruce E. Strober asserted at the annual congress of the European Academy of Dermatology and Venereology.

Bruce Jancin/Frontline Medical News

That’s a key issue whenever a dermatologist prescribes a potent immune-altering anti-inflammatory medication for an indefinite period of time, he added.

In the randomized trials in which more than 2,300 patients who received 80 mg of ixekizumab every 2 or 4 weeks were compared with 739 patients assigned to etanercept (Enbrel) and 791 on placebo, malignancy rates were similarly low, at 0.1-0.3 cases per 100 patient-years across all four treatment arms, reported Dr. Strober, chair of the department of dermatology at the University of Connecticut, Farmington.

Moreover, in the long-term maintenance studies featuring 60 months of follow-up, the risks of both nonmelanoma skin cancer and other types of cancer were similarly low in patients randomized to ixekizumab at 80 mg every 2 weeks and those dosed every 4 weeks. That’s reassuring, because if a drug causes cancer one would expect to see that the more of the drug given, the higher the malignancy rate.

“You really don’t see any kind of a pattern or any difference between the various compared groups, including patients on etanercept, a drug that all of us feel very comfortable using in patients with psoriasis,” the dermatologist observed.

It’s thought that psoriasis patients have a higher background risk of malignancy than the general population due to the nature of the chronic disease, which involves immune dysregulation and chronic inflammation. In the studies to date, however, the malignancy risk in ixekizumab-treated patients is similar to those on placebo or etanercept.

“In my opinion, it’s comforting that the malignancy rates of the currently approved biologic agents for psoriasis are low and – one could argue – not above that which you would expect for the population of patients we’re treating. So I’ve always felt that monotherapy – and that’s an important point, not combination therapy with other immunosuppressive drugs – offers very little risk of de novo malignancy with the currently approved biologics,” Dr. Strober said.

Lumping together the results of the seven studies in his analysis, the incidence of squamous cell carcinoma was 0.1 cases per 100 patient-years of ixekizumab exposure, the risk of basal cell carcinoma was 0.3 cases per 100 patient-years, and the risk of malignancies other than nonmelanoma skin cancer was 0.5 per 100 patient-years of exposure to ixekizumab.

“That’s basically in line with every other biologic that I’ve examined with regard to malignancy rates: about 1 in 200 patients treated for 1 year gets a nonmelanoma skin cancer of some nature if you look at all data sources, including long-term registries and clinical trials. So it appears that this drug falls right in line with the other biologics in terms of rates of the more serious cancers, at least over the time period studied,” Dr. Strober commented.

He offered a caveat, however: “What will happen in patients given combination therapy with other immunosuppressive drugs? Or special populations, such as patients at higher risk for malignancy, be it skin cancer or other types of cancer? Or – and here’s the question we often have the most difficulty answering – what about people with a prior history of malignancy? What would be their risk of malignancy in being placed on a drug of this nature? Only time and really good registry data will allow us to answer these questions.”

Dr. Strober is a consultant to Eli Lilly, which sponsored the seven ixekizumab studies, as well as to numerous other pharmaceutical companies.

In the randomized trials in which more than 2,300 patients who received 80 mg of ixekizumab every 2 or 4 weeks were compared with 739 patients assigned to etanercept (Enbrel) and 791 on placebo, malignancy rates were similarly low, at 0.1-0.3 cases per 100 patient-years across all four treatment arms, reported Dr. Strober, chair of the department of dermatology at the University of Connecticut, Farmington.

Moreover, in the long-term maintenance studies featuring 60 months of follow-up, the risks of both nonmelanoma skin cancer and other types of cancer were similarly low in patients randomized to ixekizumab at 80 mg every 2 weeks and those dosed every 4 weeks. That’s reassuring, because if a drug causes cancer one would expect to see that the more of the drug given, the higher the malignancy rate.

“You really don’t see any kind of a pattern or any difference between the various compared groups, including patients on etanercept, a drug that all of us feel very comfortable using in patients with psoriasis,” the dermatologist observed.

It’s thought that psoriasis patients have a higher background risk of malignancy than the general population due to the nature of the chronic disease, which involves immune dysregulation and chronic inflammation. In the studies to date, however, the malignancy risk in ixekizumab-treated patients is similar to those on placebo or etanercept.

“In my opinion, it’s comforting that the malignancy rates of the currently approved biologic agents for psoriasis are low and – one could argue – not above that which you would expect for the population of patients we’re treating. So I’ve always felt that monotherapy – and that’s an important point, not combination therapy with other immunosuppressive drugs – offers very little risk of de novo malignancy with the currently approved biologics,” Dr. Strober said.

Lumping together the results of the seven studies in his analysis, the incidence of squamous cell carcinoma was 0.1 cases per 100 patient-years of ixekizumab exposure, the risk of basal cell carcinoma was 0.3 cases per 100 patient-years, and the risk of malignancies other than nonmelanoma skin cancer was 0.5 per 100 patient-years of exposure to ixekizumab.

“That’s basically in line with every other biologic that I’ve examined with regard to malignancy rates: about 1 in 200 patients treated for 1 year gets a nonmelanoma skin cancer of some nature if you look at all data sources, including long-term registries and clinical trials. So it appears that this drug falls right in line with the other biologics in terms of rates of the more serious cancers, at least over the time period studied,” Dr. Strober commented.

He offered a caveat, however: “What will happen in patients given combination therapy with other immunosuppressive drugs? Or special populations, such as patients at higher risk for malignancy, be it skin cancer or other types of cancer? Or – and here’s the question we often have the most difficulty answering – what about people with a prior history of malignancy? What would be their risk of malignancy in being placed on a drug of this nature? Only time and really good registry data will allow us to answer these questions.”

Dr. Strober is a consultant to Eli Lilly, which sponsored the seven ixekizumab studies, as well as to numerous other pharmaceutical companies.

COPENHAGEN – Secukinumab maintained consistently high and previously unheard of long-term Psoriasis Area and Severity Index 90 and PASI 100 response rates in psoriasis patients through 3 years of prospective follow-up in an extension of the phase III SCULPTURE trial.

The key to maintaining these high response rates was to give secukinumab (Cosentyx) on a fixed schedule every 4 weeks. SCULPTURE tested the hypothesis that retreatment of initial responders only as needed based upon early evidence of relapse off treatment might be a reasonable alternative strategy. The answer turns out to be emphatically no.

“We can see from the 3-year data that retreatment as needed is probably not a good strategy over the long term. We see four times fewer patients with PASI 90s and 10 times fewer patients with PASI 100s if they are treated as needed. From the patient point of view, quality of life and satisfaction are not optimal with retreatment as needed,” Dr. Diamant Thaci said at the annual congress of the European Academy of Dermatology and Venereology.

The 3-year extension of SCULPTURE also provided reassuring safety data, he noted.

“It’s interesting that with long-term treatment out to 3 years, we don’t see any new safety signals. In fact, the signals we saw in the preapproval studies are slightly diluted here, and now that secukinumab is approved, we’re not seeing them as problems in real life clinical practice,” said Dr. Thaci of University Hospital in Lübeck, Germany.

The 52-week SCULPTURE results were published earlier this year (J Am Acad Dermatol. 2015 Jul;73[1]:27-36). Dr. Thaci’s update extended the findings from 52 weeks through 3 years.

The double-blind phase of the core SCULPTURE study began with 966 patients with moderate to severe plaque psoriasis and a baseline PASI score of about 23. After 12 weeks on subcutaneous secukinumab, the 842 subjects who had achieved 75% or more improvement from their baseline PASI score were randomized to one of four study arms: secukinumab at either 300 mg or 150 mg, administered either every 4 weeks or by retreatment as needed when an individual’s response dropped below PASI 75.

Picking up where the published 52-week results left off, Dr. Thaci focused special attention on the PASI 90 outcomes out to 3 years because he said he believes PASI 90 will become generally accepted as the new treatment target, now that secukinumab is on the market and other supereffective biologic agents are advancing through the developmental pipeline.

At 52 weeks, 68.5% of patients on fixed-dose secukinumab at 300 mg every 4 weeks had a PASI 90 response. At 3 years, after an additional 2 years on this schedule, the PASI 90 rate was still hovering around the two-thirds mark at 63.8%. In contrast, patients on retreatment with 300 mg as needed had a PASI 90 rate of 14.8% at 52 weeks and 13% at 3 years.

Although the Food and Drug Administration recommended the 300-mg dose when it approved secukinumab as a first-in-class biologic in January, the agency added that 150 mg may be acceptable in some patients. But the 150-mg dose was clearly inferior long term in the SCULPTURE extension. At 52 weeks, 50.3% of patients on secukinumab at 150 mg every 4 weeks had a PASI 90 response; at 3 years the rate was 36.8%. With retreatment as needed using 150 mg, the 52-week and 3-year PASI 90 rates were 12% and 11.8%, Dr. Thaci reported.

The PASI 100 (clear skin) response rate at 52 weeks with fixed-dose secukinumab at 300 mg was 43.8%. At 3 years it was 42.6%.

“These excellent responders kept their excellent response by continuing treatment for 3 years,” the dermatologist noted.

The PASI 100 rates with retreatment as needed were 5.3% and 3.8%.

In terms of safety through 3 years of treatment, rates of the adverse events of greatest interest with the use of immunomodulatory therapies – Candida infections, malignancies, serious infections, and major adverse cardiovascular events – were similarly low across all four treatment arms, ranging from 0 to 1.6 events per 100 subject-years. Thus, there was no safety advantage in using the retreatment as needed strategy.

“In the past we were all talking about the risk of Candida infection caused by inhibiting [interleukin]-17. But if you treat patients in real life clinical practice, you may see a signal of Candida infection in the beginning, yet in the long term you don’t see Candida as a significant side effect in our daily practice – and in this trial the incidence decreases,” Dr. Thaci said.

One audience member rose to criticize the way the analysis of the long-term extension of SCULPTURE was structured – namely, that only patients still on secukinumab at the 3-year mark were included in the results. This “as-observed” method inflates the efficacy results, he said. How many patients dropped out over time and weren’t counted? he asked.

Dr. Thaci replied that roughly 90% of patients in the trial at 52 weeks continued on secukinumab out to 3 years.

“It’s not a massive dropout. I wish it were a nonresponder imputation analysis, but in long-term studies, it’s very difficult to show that analysis because the vast majority of the trials that have been presented in the past have been ‘as observed.’ But I don’t think you’ll see a big difference between this as-observed analysis and a nonresponder imputation analysis. This is a very fair and convincing analysis,” he said.

Secukinumab is marketed by Novartis, which sponsored the study. Dr. Thaci serves as an investigator and consultant to Novartis and other pharmaceutical companies.

COPENHAGEN – What can physicians and their psoriasis patients realistically expect from long-term apremilast therapy?

“I think the take-home number is a 50%-plus PASI-75 response after 1 year among patients with moderate to severe plaque psoriasis,” Dr. Kristian Reich said at the annual congress of the European Academy of Dermatology and Venereology.

He presented what he considers to be the first solid data addressing this key question. The data come from a new analysis of the 52-week results of the LIBERATE trial.

“Due to the randomized withdrawal design and long-term treatment only of responders in the original pivotal phase III ESTEEM program, I think we’ve had no real understanding from clinical trials of what the long-term efficacy of apremilast [Otezla] is. Of course, with psoriasis being a chronic disease, this is really what we want to know. And we can get this data very nicely from the LIBERATE study. I should point out that although LIBERATE is a relatively small study, every single patient is included here. So I think this is a very robust analysis of 1-year efficacy data,” said Dr. Reich, managing partner of Dermatologikum Hamburg (Germany).

In contrast to the inclusive analysis performed in LIBERATE, in the pivotal ESTEEM I trial a mere 77 of 562 psoriasis patients randomized to apremilast were on the oral phosphodiesterase type 4 inhibitor for the full 52-week study period, with 61% of that superselect subgroup showing a PASI-75 response (J Am Acad Dermatol. 2015 Jul;73[1]:37-49).

LIBERATE included 250 psoriasis patients. Their baseline Psoriasis Area and Severity Index (PASI) score was about 20, with 27% body surface area involved, a body mass index of 29 kg/m², 89 kg of body weight, and a mean Dermatology Life Quality Index (DLQI) score of 13. Seventy percent to 80% of subjects had previously used conventional systemic therapies, but no one was allowed to have prior use of biologic therapies.

Patients were randomized to one of three study arms: 16 weeks of oral apremilast at the approved dose of 30 mg twice daily plus a weekly placebo injection, subcutaneous etanercept (Enbrel) at 50 mg once weekly plus a placebo tablet, or dual placebos. At 16 weeks, all patients were switched to apremilast at 30 mg twice daily with no placebos through week 52.

The PASI-75 response rate at week 16 was 11.9% in the placebo group, 39.8% with apremilast, and 48.2% with etanercept.

“I am surprised to see in the more recent studies the high response to etanercept. This is fantastic data. Etanercept seems to ripen like old wine. It’s getting better the longer we have it,” the dermatologist commented.

The PASI-75 rates at 1 year were 46.4% with placebo/apremilast, 50.6% with apremilast throughout, and 55.4% with etanercept/apremilast.

The mean improvement in DLQI from baseline to 52 weeks – a secondary endpoint – was 6.6 points with placebo/apremilast, 8.0 with apremilast/apremilast, and 8.9 points with etanercept/apremilast. A noteworthy finding was that during the first 16 weeks apremilast brought a clinically meaningful improvement in quality of life significantly faster than etanercept did, with a significant difference seen between the two study arms even in the first 1-2 weeks.

The likely explanation for this benefit is that the mean reduction in pruritus visual analog scale scores was significantly greater with apremilast than etanercept through the first 8 weeks. Although pruritus is traditionally thought of more in the context of atopic dermatitis, it’s actually also the No. 1 complaint among psoriasis patients, according to Dr. Reich.

“This is a special thing with apremilast, that the pruritus really goes down very significantly early on. It raises an interesting question about what the role of phosphodiesterase-4 inhibition might be in pruritus. I couldn’t give you a molecular explanation, but I think because pruritus is so annoying and it definitely affects quality of life, this could be a possible explanation for why there is more rapid improvement in quality of life independent of the PASI improvement,” he said.

Switching from etanercept to apremilast didn’t result in any clinically significant safety findings through week 52. No meaningful laboratory changes occurred during 52 weeks of monitoring. There were no cases of suicidal ideation, no increase in serious infections, and only a single cardiac event. The most common apremilast-associated side effects seen in LIBERATE were loose stools in 8%-15% of patients, nausea in 10%, and headache in 13%. These adverse events were mild to moderate in nature and decreased in prevalence over time. The maximum weight loss noted over the course of 52 weeks occurred in the placebo-to-apremilast group, with a mean 1.3-kg reduction.

“I would call the LIBERATE results a validation of the earlier data showing a very clean safety profile with this drug,” Dr. Reich said.

This is reflected in the product labeling, which unlike other systemic therapies for psoriasis includes no requirements for laboratory monitoring or tuberculosis testing.

Both the LIBERATE and the ESTEEM trials were sponsored by Celgene. Dr. Reich received research grants as an investigator in both programs.

In contrast to the inclusive analysis performed in LIBERATE, in the pivotal ESTEEM I trial a mere 77 of 562 psoriasis patients randomized to apremilast were on the oral phosphodiesterase type 4 inhibitor for the full 52-week study period, with 61% of that superselect subgroup showing a PASI-75 response (J Am Acad Dermatol. 2015 Jul;73[1]:37-49).

LIBERATE included 250 psoriasis patients. Their baseline Psoriasis Area and Severity Index (PASI) score was about 20, with 27% body surface area involved, a body mass index of 29 kg/m², 89 kg of body weight, and a mean Dermatology Life Quality Index (DLQI) score of 13. Seventy percent to 80% of subjects had previously used conventional systemic therapies, but no one was allowed to have prior use of biologic therapies.

Patients were randomized to one of three study arms: 16 weeks of oral apremilast at the approved dose of 30 mg twice daily plus a weekly placebo injection, subcutaneous etanercept (Enbrel) at 50 mg once weekly plus a placebo tablet, or dual placebos. At 16 weeks, all patients were switched to apremilast at 30 mg twice daily with no placebos through week 52.

The PASI-75 response rate at week 16 was 11.9% in the placebo group, 39.8% with apremilast, and 48.2% with etanercept.

“I am surprised to see in the more recent studies the high response to etanercept. This is fantastic data. Etanercept seems to ripen like old wine. It’s getting better the longer we have it,” the dermatologist commented.

The PASI-75 rates at 1 year were 46.4% with placebo/apremilast, 50.6% with apremilast throughout, and 55.4% with etanercept/apremilast.

The mean improvement in DLQI from baseline to 52 weeks – a secondary endpoint – was 6.6 points with placebo/apremilast, 8.0 with apremilast/apremilast, and 8.9 points with etanercept/apremilast. A noteworthy finding was that during the first 16 weeks apremilast brought a clinically meaningful improvement in quality of life significantly faster than etanercept did, with a significant difference seen between the two study arms even in the first 1-2 weeks.

The likely explanation for this benefit is that the mean reduction in pruritus visual analog scale scores was significantly greater with apremilast than etanercept through the first 8 weeks. Although pruritus is traditionally thought of more in the context of atopic dermatitis, it’s actually also the No. 1 complaint among psoriasis patients, according to Dr. Reich.

“This is a special thing with apremilast, that the pruritus really goes down very significantly early on. It raises an interesting question about what the role of phosphodiesterase-4 inhibition might be in pruritus. I couldn’t give you a molecular explanation, but I think because pruritus is so annoying and it definitely affects quality of life, this could be a possible explanation for why there is more rapid improvement in quality of life independent of the PASI improvement,” he said.

Switching from etanercept to apremilast didn’t result in any clinically significant safety findings through week 52. No meaningful laboratory changes occurred during 52 weeks of monitoring. There were no cases of suicidal ideation, no increase in serious infections, and only a single cardiac event. The most common apremilast-associated side effects seen in LIBERATE were loose stools in 8%-15% of patients, nausea in 10%, and headache in 13%. These adverse events were mild to moderate in nature and decreased in prevalence over time. The maximum weight loss noted over the course of 52 weeks occurred in the placebo-to-apremilast group, with a mean 1.3-kg reduction.

“I would call the LIBERATE results a validation of the earlier data showing a very clean safety profile with this drug,” Dr. Reich said.

This is reflected in the product labeling, which unlike other systemic therapies for psoriasis includes no requirements for laboratory monitoring or tuberculosis testing.

Both the LIBERATE and the ESTEEM trials were sponsored by Celgene. Dr. Reich received research grants as an investigator in both programs.

COPENHAGEN – Ixekizumab not only shows considerable promise for the treatment of moderate to severe psoriasis, it looks like it may be a winner for comorbid psoriatic arthritis, too.

The investigational IgG4 humanized monoclonal antibody directed against interleukin-17A brought marked improvements in joint pain, systemic inflammatory burden, and quality of life as well as skin disease in patients with both psoriasis and self-reported psoriatic arthritis in a combined analysis of three phase III clinical trials, Dr. Alice B. Gottlieb reported at the annual congress of the European Academy of Dermatology and Venereology.

Of the 3,126 patients with moderate to severe psoriasis who participated in the 12-week, phase III UNCOVER-1, -2, and -3 trials, 751 (24%) also had self-reported psoriatic arthritis; her analysis focused on them.

She was quick to note that the UNCOVER trials were primarily psoriasis studies that relied upon patient self-report of psoriatic arthritis. Nevertheless, it seems likely that the great majority of self-reported psoriatic arthritis patients really did have the rheumatologic disease, since the mean baseline C-reactive protein (CRP) level in that group was 8.43 mg/L, a level far higher than expected in patients with psoriasis only.

In any case, more-rigorous phase III studies of ixekizumab conducted specifically in patients with formally rheumatologist-diagnosed psoriatic arthritis and treated in rheumatology practices are due to be presented at the annual meeting of the American College of Rheumatology in November. And while Dr. Gottlieb wasn’t at liberty to discuss those results, she did hint that the data will be strongly positive.

“If you’re happy about these UNCOVER findings, you’ll be ecstatic about those,” predicted Dr. Gottlieb, professor of dermatology and dermatologist in chief at Tufts Medical Center, Boston.

Also coming up at the American College of Rheumatology meeting will be the results of the first-ever head-to-head comparison of an IL-17 inhibitor versus a tumor necrosis factor–alpha blocker in psoriatic arthritis patients. While at present most physicians consider a TNF inhibitor to be the treatment of choice in patients with psoriatic arthritis, that view may change as a result of the forthcoming comparative study, according to the dermatologist.

In each of the three phase III UNCOVER studies, patients were randomized to 12 weeks of subcutaneous ixekizumab at 80 mg every 2 or 4 weeks following a 160-mg loading dose, or to placebo. At baseline, the subgroup with self-reported psoriatic arthritis had a mean Psoriasis Area and Severity Index ( PASI) 0f about 21, a self-rated joint pain severity of 50 on a 0-100 scale, a CRP of 8.43 mg/L, and a Dermatology Life Quality Index (DLQI) score of 14.

Joint pain decreased dramatically in the two ixekizumab groups as early at 2 weeks into the trial, at which point, patients on treatment every 2 weeks averaged a 13.1-point reduction from baseline, with a similar 14.1-point drop noted in those on an every 4 weeks schedule. At week 12, the mean reductions from baseline were 25.2 and 26.8 points, compared with a 1.1-point increase in joint pain among placebo-treated controls.

Inflammatory burden plunged quickly, as evidenced by mean reductions in CRP of 4.63 mg/L and 4.33 mg/L at week 1 with biweekly and monthly dosing, respectively. These reductions were then maintained through week 12.

In terms of improvement in skin symptoms, with ixekizumab dosed every 2 weeks, the PASI 75 response was 89.8% at 12 weeks, the PASI 90 response was 69.3%, and the PASI 100 response (clear skin) was 37.1%. In patients treated every 4 weeks, the rates were 81.1%, 60.8%, and 34.7%.

“There’s good news in both groups, but I think the news is even better in the every-2-weeks group,” Dr. Gottlieb commented.

The mean 12-week decrease from baseline in DLQI was 11.8 points with biweekly dosing and 10.5 with 4-week dosing, compared with 0.8 points in controls. That’s impressive given that a 5-point reduction in DLQI is deemed clinically meaningful, the dermatologist observed. At 12 weeks, 56.5% of patients on ixekizumab every 2 weeks had a DLQI of 0 or 1, as did 54% on monthly dosing and 1.5% of controls.

The ixekizumab-treated groups also showed what Dr. Gottlieb described as “dramatic” improvements – in the 4+ to 5+ point range – in both the mental and physical component scores on the SF-36, another widely used quality of life measure.

Improvements in skin and self-reported joint symptoms appeared to correlate. Patients with a PASI 50 to less-than PASI 75 response had a mean 17-point reduction in joint pain scores, while those with a PASI 75 to less-than PASI 90 response averaged a 25.1-point improvement in joint pain, patients with a PASI 90 to less-than PASI 100 skin response averaged a 27.6-point reduction, and PASI 100 responders had a mean 30.3-point reduction in joint pain scores.

“Obviously, one needs to look at this more carefully in a phase III psoriatic arthritis study. That’ll provide a more robust answer. But this gives a hint,” the dermatologist said.

The UNCOVER program was sponsored by Eli Lilly. Dr. Gottlieb serves as an adviser to Lilly and numerous other pharmaceutical companies.
