Newer IL-17 inhibitors make their case in phase 3 nonradiographic axial spondyloarthritis trials

Article Type

Fri, 11/22/2019 - 11:28

A major gap in interleukin-17 inhibitor (IL-17i) therapy for axial spondyloarthritis (axSpA) was evidence of efficacy in nonradiographic axSpA. At ACR 2019, we saw two different IL-17i studies showing efficacy in nr-axSpA patients. Now we know that both secukinumab and ixekizumab are effective in the full spectrum of axSpA patients (ankylosing spondylitis [AS] and nr-axSpA).

Dr. Nigil Haroon

The majority of clinicians would consider both AS and nr-axSpA to be driven by common processes and so drugs that are effective on one should have the same effect in the other as well. Hence the results are not a big surprise. In certain places, an approved indication for use may be important especially for reimbursement purposes. These results are likely to have maximal impact there.

The COAST-X study on ixekizumab was designed in a way similar to that of the C-axSpAnd study with certolizumab pegol. There was an extended 52-week placebo arm to study the natural history of nr-axSpA patients who are not actively treated with biologics. This design was necessary to respond to the Food and Drug Administration’s concern that, in the absence of this prolonged observation on placebo, we cannot be sure that nr-axSpA patients are not spontaneously remitting (not due to biologics).



However, the results here did surprise me. Unlike in the C-axSpAnd trial where only 13% of actively treated patients (on certolizumab pegol) switched to open-label treatment, in the COAST-X study 40% of patients on both doses of ixekizumab opted for open-label treatment. The number of patients moving out of the placebo arm was around 60% (similar in both studies). There are no straightforward factors evidently explaining this discrepancy. Between 15% and 25% of patients who switched had achieved the primary endpoint of ASAS40. Does this reflect that ASAS40 is not acceptable to patients? As the results show responses plateaued after week 16, it could be that the patients who switched might have done so well into the 52-week observation period.

Patients in the COAST-X study had slightly longer disease duration and marginally lower HLA-B27 prevalence (both factors may indicate lower chance of treatment response).

The primary endpoint of ASAS40 was met at weeks 16 and 52 with significantly higher rates seen with ixekizumab than with placebo. Again the response seems to plateau around 16 weeks with minimal gain up to week 52.



The results from the secukinumab PREVENT study are very similar to those of the COAST-X study showing the superiority of secukinumab over placebo in treating nr-axSpA patients. Interestingly, if we do not use the loading dose for secukinumab, there does not seem to be any difference from standard treatment with loading. This may have economic and administrative implications on the decision to use loading doses of secukinumab. We should carefully consider the MEASURE 4 trial results before making decisions on the utility of loading doses. In the MEASURE 4 study on AS patients, although there was no difference between load and no load arms of secukinumab (around 60% ASAS20 response in both arms), there was no significant gain above placebo with both doses. (The primary endpoint was not met.) This is likely due to the high placebo response (47% ASAS20 response). Similarly, we see a high placebo response in the COAST-X study as well, with an ASAS40 response rate of about 40% in active secukinumab arms vs. 30% in the placebo arm.

The number of patients dropping out over the 52-week follow-up period was not discussed in the PREVENT trial presentation.

There is not much here to favor one IL-17i over the other.

COAST-X top-line results: Ixekizumab improves nonradiographic axSpA vs. placebo

– Adding ixekizumab (Taltz) to conventional background medications significantly improved the signs and symptoms of nonradiographic axial spondyloarthritis (axSpA) in the randomized, double-blind, placebo-controlled phase 3 COAST-X trial.

Sharon Worcester/MDedge News
Dr. Atul Deodhar

The high-affinity interleukin-17A monoclonal antibody ixekizumab “has shown efficacy in ankylosing spondylitis – also called radiographic axial spondyloarthritis – [and] it recently was approved by the [Food and Drug Administration] for the treatment of active ankylosing spondylitis,” said Atul Deodhar, MD, explaining that COAST-X sought to assess its efficacy in patients with active nonradiographic axSpA and objective evidence of inflammation. He presented the results of the trial at the annual meeting of the American College of Rheumatology.

Of 303 adults with an established diagnosis of axSpA who met Assessment of Spondyloarthritis International Society (ASAS) classification criteria and who were enrolled in the 52-week trial, 105 were randomized to receive background medications plus placebo, and 102 and 96 received background medications plus ixekizumab every 2 or 4 weeks, respectively. The primary endpoint of a 40% improvement in ASAS response criteria (ASAS 40) was reached at week 16 by 19% of the placebo-group patients and by 35% and 40% of the 2- and 4-week ixekizumab-group patients, and at week 52 by 13%, 30%, and 31% of the patients in the groups, respectively, Dr. Deodhar reported.



Additionally, “all major secondary endpoints were met for each ixekizumab regimen, both at week 16 and week 52,” said Dr. Deodhar, professor of medicine in the division of arthritis and rheumatic diseases at Oregon Health & Science University, Portland.

For example, Ankylosing Spondylitis Disease Activity Score (ASDAS) at week 16 declined by 0.6 with placebo, 1.3 with 2-week ixekizumab dosing, and 1.1 points with 4-week ixekizumab dosing; Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Functional Index changes were –1.5, –2.5, and –2.2, and –1.3, –2.3 and –2.0; Short Form–36 physical component score changes were 5.3, 8.0, and 8.1 points; and MRI sacroiliac joint Spondyloarthritis Research Consortium of Canada score changes were –0.3, –4.5 and –3.4, in the groups, respectively.

“ASDAS less than 2.1 – low disease activity – was achieved by 32% and 27% [in the 2- and 4-week ixekizumab groups] versus 12% in the placebo [group],” he said, noting that similarly significant results were seen at week 52.

Notably, the differences in ASAS 40 response rates between the treatment and placebo groups were observed beginning at week 1, and “a notable proportion” of patients who escaped to the open-label 2-week ixekizumab group, as allowed per study protocol starting at week 16, had an ASAS 40 response at the time of escape; the ASAS 40 response rates at that time were 6.5%, 16.7%, 25% in the groups, respectively, and the rates increased further on open-label ixekizumab, he said.

Study participants were adults diagnosed with axSpA by a physician and treated for at least 3 months. Inclusion criteria also included BASDAI score of at least 4, back pain score of at least 4, inflammation as evidenced by sacroiliitis on MRI or elevated C-reactive protein levels of greater than 5 mg/L, and inadequate response or intolerance to at least two NSAIDs.



Ixekizumab in both treatment groups was given at a dose of 80 mg, and changes to conventional background medications, including NSAIDs, conventional synthetic disease-modifying antirheumatic drugs, analgesics, and low-dose corticosteroids, were allowed, as was escape to open-label ixekizumab given every 2 weeks at investigators’ discretion after week 16.

Ixekizumab treatment was well tolerated; the frequency of serious adverse events and AEs leading to treatment discontinuation was low and similar across all arms, Dr. Deodhar said.

For example, treatment-emergent AEs occurred in 55.7%, 77.5%, and 65.6% of patients, serious AEs occurred in 1.0%, 1.0%, and 2.1%, and AE-related discontinuations occurred in 1.9%, 1.0%, and 1.0% or patients in the groups, respectively.

No deaths occurred and no new safety signals were identified.

“The results demonstrate, for the first time, that blocking IL-17A is a potential treatment option for patients with nonradiographic axSpA,” he concluded.

COAST-X was sponsored by Eli Lilly. Dr. Deodhar and most coauthors reported receiving research grants and/or honoraria for consulting or speaking from Eli Lilly and other pharmaceutical companies. Four authors are current employees and shareholders of Eli Lilly.

FDA announces approval of fifth adalimumab biosimilar, Abrilada

Article Type
Changed
Tue, 02/07/2023 - 16:51

The Food and Drug Administration has cleared adalimumab-afzb (Abrilada) as the fifth approved Humira biosimilar and the 25th approved biosimilar drug overall, the agency said in a Nov. 15 announcement.

Olivier Le Moal/Getty Images

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

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

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

PREVENT trial shows benefits of secukinumab for nonradiographic axSpA

Article Type

Fri, 11/15/2019 - 12:07

– Patients with nonradiographic axial spondyloarthritis who received secukinumab with or without loading doses showed improvements in physical function, quality of life, inflammation, and other disease signs and symptoms, according to results from a phase 3 study presented at the annual meeting of the American College of Rheumatology.

Jeff Craven/MDedge News
Dr. Atul Deodhar

For patients with nonradiographic axial spondyloarthritis in the double-blind, randomized, placebo-controlled PREVENT trial, these benefits persisted up to 52 weeks, Atul A. Deodhar, MD, professor of medicine in the division of arthritis and rheumatic diseases at Oregon Health & Science University, Portland, said in his presentation.

“This is the largest study done for a biologic agent in nonradiographic axial spondyloarthritis,” Dr. Deodhar said. The trial enrolled 185 patients who received subcutaneous secukinumab (Cosentyx) at a dose of 150 mg, 184 patients who received the medication without a loading dose, and 186 patients who received placebo.

Patients were included if they were aged at least 18 years with 6 months or more of inflammatory back pain, had objective signs of inflammation (sacroiliitis on MRI and/or C-reactive protein [CRP] at 5.0 mg/dL or higher), had active disease and spinal pain according to the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), had total back pain with a visual analog scale of 40 mm or greater, and had not received a tumor necrosis factor inhibitor (TNFi) or had an inadequate response to no more than one TNFi. Patients were also stratified by inflammation measured on MRI and CRP. A little more than half of the patients in each group were women, and at baseline their mean age was 39 years, with a mean symptom duration of more than 8 years and mean Ankylosing Spondylitis Disease Activity Score of 3.5-3.7.

The primary endpoint was at least 40% improvement in Assessment of Spondyloarthritis International Society response criteria (ASAS40) at 16 weeks to meet European Union regulatory requirements and at 52 weeks for the Food and Drug Administration. Escape to open-label secukinumab or standard of care was permitted any time after week 20 for patients deemed to have inadequate response based on clinical judgment of disease activity by the investigator and patient; at 52 weeks, the trial became open label and patients in the placebo group could begin secukinumab or standard of care. The U.S. and European Union analyses were performed independently, with the European analysis including only secukinumab with loading doses and the U.S. analysis including secukinumab without loading.

At 16 weeks, an analysis of the overall population showed that 40.8% of patients in the secukinumab nonloading group had an ASAS40 response, compared with 40.0% in those who got a loading dose and 28.0% with placebo (P less than .05 for both). Among the 90% of patients who were TNFi naive, ASAS40 responses occurred in 42.2% of patients in the nonloading group, 41.5% who received a loading dose, and 29.2% with placebo (P less than .05 for both). ASAS40 response rates persisted at 52 weeks for patients in the nonloading (39.8%), loading (35.4%), and placebo (19.9%) groups (P less than .05).

Over the same time period, the least-square mean changes in total BASDAI score improved from baseline by 2.43 in the nonloading group, 2.35 in the loading group, and 1.46 in the placebo group (P less than .05). The percentage of patients who had 50% or greater improvement in BASDAI was 37% in both treatment groups, compared with 21% with placebo (P less than .05).

Function score as measured by the Bath Ankylosing Spondylitis Functional Index also showed significantly greater improvements at 16 weeks for both loading and nonloading patients versus placebo (–1.75 and ­–1.64 vs. –1.01; P less than .05). Treatment with or without a loading dose led to significant reductions in sacroiliac joint edema on MRI and high-sensitivity CRP. The percentage patients who met ASAS partial remission criteria were significantly higher in the loading (21.6%) and nonloading (21.2%) groups, compared with placebo (7.0%; P less than .05).

Physical function and quality of life assessments at 16 weeks using the 36-item Short Form Health Survey physical component score and the Ankylosing Spondylitis Quality of Life questionnaire showed significant improvements both with and without a loading dose.

There were no new safety concerns with secukinumab that arose in the trial, Dr. Deodhar said.

Dr. Deodhar admitted the placebo effect was high in the PREVENT study, but noted that this was a reoccurring problem in other areas of rheumatology. “The rates are going up in several studies, including in RA, so [in terms of] axial spondyloarthritis and why that happens, we really don’t know.”

When asked about the effect of the loading dose, Dr. Deodhar said that “the load is not really going to take over or have different response by 52 weeks; the load would have a response by 8 weeks or maybe 12 weeks, but then beyond that, I don’t think the load would have any response at all.

“In my clinical experience, speaking outside this trial, load obviously helps the patient quickly to feel better, and so that’s the way I practice my medicine,” he added.

The PREVENT study was sponsored by Novartis, which markets secukinumab. Some of the authors reported relationships with Novartis and many other pharmaceutical companies. Four authors were employees of Novartis.

Spinal progression found more often in men with ankylosing spondylitis

Wed, 11/06/2019 - 12:09

 

Patients with ankylosing spondylitis who are male, have evidence of spinal damage, or have higher levels of inflammatory markers may be at higher risk of disease progression, a study has found.

“Assessment of AS-related structural changes longitudinally is essential for understanding the natural course of progression and its underlying factors,” Ismail Sari, MD, of the University of Toronto and coauthors wrote in Arthritis Care & Research. “This could help identify the mechanisms responsible for progression and thereby personalizing treatment.”

The researchers found that nearly one-quarter (24.3%) of 350 individuals with ankylosing spondylitis in a longitudinal cohort study showed radiographic evidence of progression, defined as a change of 2 units on the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) in 2 years. Overall, 76% of the group were males, and the group had a mean age of about 38 years with a mean symptom duration of nearly 15 years.

Over the 6-year follow-up, the mean mSASSS increased from 9.3 units at baseline to 17.7 units, with more progression seen in the cervical spine than the lumbar segments. During the first 2 years, the total mSASSS increased by a mean of 1.23 units; in years 2-4, it increased by a mean of 1.47 units, and from 4 to 6 years, it increased by a mean of 1.52 units.

Male sex was associated with more than double the risk of radiographic progression (hazard ratio, 2.46; 95% confidence interval, 1.05-5.76), while individuals with radiographic evidence of spinal damage at baseline had a nearly eightfold higher risk of progression (HR, 7.98; 95% CI, 3.98-16). The risk for disease progression also increased with higher levels of C-reactive protein.

The investigators also found that patients who had used tumor necrosis factor inhibitor therapy for at least 1 year had an 18% reduction in the rate of spinal progression.

However, other factors including symptom duration, presence of HLA-B27, smoking status, presence of radiographic hip disease, or use of disease-modifying antirheumatic drugs or NSAIDs did not appear to influence the risk of disease progression.

No funding or conflicts of interest were declared.

Trials examine T2T strategy in axial spondyloarthritis

Article Type
Changed
Fri, 10/25/2019 - 08:50

 

Three international clinical trials in Europe are examining the effectiveness of treat-to-target (T2T) therapeutic regimens in patients with axial spondyloarthritis (axSpA), including two that will be the first randomized trial evidence to support or refute the T2T strategy for patients ranging from those with nonradiographic disease to patients with ankylosing spondylitis.

T2T has proved before to work in patients with rheumatoid arthritis and psoriatic arthritis with evidence from the TICORA (Tight Control of Rheumatoid Arthritis) and TICOPA (Tight Control in Psoriatic Arthritis) trials.

Two T2T trials in axSpA are still in the recruiting phase, and one has completed enrollment, with no results available yet.
 

Tight control in spondyloarthritis (TICOSPA)

TICOSPA is a 1-year, ongoing, multinational, cluster-randomized, prospective cohort study that has enrolled 163 patients with a diagnosis of active axial spondyloarthritis to evaluate the potential benefit of a T2T strategy in which the rheumatologist will agree to monitor very closely – at least every 4 weeks – and treat patients in accordance with a predefined strategy. The T2T strategy is compared with usual care as given by the treating rheumatologist. Prior to the trial, patients were on nonoptimal NSAID treatment.

“Tight control” in this study refers to the time from treatment initiation to adequate assessment of efficacy and safety, which for efficacy should be at 2-4 weeks for NSAIDs and 12-16 weeks for tumor necrosis factor inhibitors but can be a very short time frame for evaluating safety, “based on the occurrence of adverse events,” according to the study description at clinicaltrials.gov.

The primary endpoint is change on the Assessment of SpondyloArthritis international Society (ASAS) Health Index-Numerical Rating Score over the 1 year of follow-up.

There are 11 secondary endpoints, including:

  • Percentage reaching major improvement in the Ankylosing Spondylitis Disease Activity Scale score (ASDAS).
  • Percentage reaching 50% improvement of the initial Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score at 1 year.
  • Change in the ASAS-NSAID score over 1 year.
  • Change in the Work Productivity and Activity Impairment questionnaire.

The study is being conducted at 18 centers in Belgium, France, and the Netherlands and is sponsored by the Association de Recherche Clinique en Rhumatologie.
 

AScalate: Treat-to-target in axial spondyloarthritis

The Novartis-sponsored AScalate study seeks to enroll 300 patients with active disease despite NSAID therapy. The 36-week, randomized, parallel-group, open-label, multicenter trial will be conducted at seven sites in Germany.

The study will randomize patients to either of two arms: An active group will receive T2T therapy with secukinumab as a first-line biologic in escalating doses of 150-300 mg, determined by patient response until the T2T goal had been reached. Patients who don’t respond to secukinumab will be switched to an adalimumab biosimilar. The comparator group will receive standard-of-care therapy up to the maximum recommended dose at the discretion of the investigator.

The primary endpoint is the percentage of patients in each group who meet ASAS 40 response criteria by 24 weeks.

There are 11 secondary endpoints, including:

 

 

  • Percentage achieving an ASAS40 response at 12 weeks.
  • Percentage achieving ASAS20 and ASAS partial response at 12 and 24 weeks.
  • Proportion of patients meeting the ASDAS definition of inactive disease, ASDAS clinically important and major improvement, and ASDAS low disease activity.
  • Proportion of patients achieving 50% improvement of the initial BASDAI score.

Treat-to-target with secukinumab in axial spondyloarthritis (TRACE)

TRACE is a Novartis-sponsored phase 4 study examining reductions of inflammation seen on MRI of sacroiliac joints and spine at 16-24 weeks in patients who achieve ASDAS remission (score of less than 1.3) on 150 mg secukinumab by 16 weeks. The comparator group will be patients who are not in remission by week 16 and need a dose increase to 300 mg. The Danish trial seeks 88 participants with high disease activity and MRI signs of inflammation in the sacroiliac joints and/ or the spine.

After an initial four weekly doses of secukinumab 150 mg, patients will receive monthly secukinumab 150-mg doses out to week 16. Nonresponders at week 16 will escalate to 300 mg. If by 24 weeks these patients do not respond, they will be switched to a TNF inhibitor.

The primary outcome is the proportion of patients with a positive change in MRI-inflammation as measured by the sum of the Spondyloarthritis Research Consortium of Canada (SPARCC) sacroiliac joint and spine inflammation indices.

The Danish trial seeks 88 participants with high disease activity and MRI signs of inflammation in the sacroiliac joints and/ or the spine.

After an initial four weekly doses of secukinumab 150 mg, patients will receive monthly secukinumab 150-mg doses out to week 16. Nonresponders at week 16 will escalate to 300 mg. If by 24 weeks these patients do not respond, they will be switched to a TNF inhibitor.

The primary outcome is the proportion of patients with a positive change in MRI-inflammation as measured by the sum of the Spondyloarthritis Research Consortium of Canada (SPARCC) sacroiliac joint and spine inflammation indices.

 

Three international clinical trials in Europe are examining the effectiveness of treat-to-target (T2T) therapeutic regimens in patients with axial spondyloarthritis (axSpA), including two that will be the first randomized trial evidence to support or refute the T2T strategy for patients ranging from those with nonradiographic disease to patients with ankylosing spondylitis.

T2T has proved before to work in patients with rheumatoid arthritis and psoriatic arthritis with evidence from the TICORA (Tight Control of Rheumatoid Arthritis) and TICOPA (Tight Control in Psoriatic Arthritis) trials.

Two T2T trials in axSpA are still in the recruiting phase, and one has completed enrollment, with no results available yet.
 

Tight control in spondyloarthritis (TICOSPA)

TICOSPA is a 1-year, ongoing, multinational, cluster-randomized, prospective cohort study that has enrolled 163 patients with a diagnosis of active axial spondyloarthritis to evaluate the potential benefit of a T2T strategy in which the rheumatologist will agree to monitor very closely – at least every 4 weeks – and treat patients in accordance with a predefined strategy. The T2T strategy is compared with usual care as given by the treating rheumatologist. Prior to the trial, patients were on nonoptimal NSAID treatment.

“Tight control” in this study refers to the time from treatment initiation to adequate assessment of efficacy and safety, which for efficacy should be at 2-4 weeks for NSAIDs and 12-16 weeks for tumor necrosis factor inhibitors but can be a very short time frame for evaluating safety, “based on the occurrence of adverse events,” according to the study description at clinicaltrials.gov.

The primary endpoint is change on the Assessment of SpondyloArthritis international Society (ASAS) Health Index-Numerical Rating Score over the 1 year of follow-up.

There are 11 secondary endpoints, including:

  • Percentage reaching major improvement in the Ankylosing Spondylitis Disease Activity Scale score (ASDAS).
  • Percentage reaching 50% improvement of the initial Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score at 1 year.
  • Change in the ASAS-NSAID score over 1 year.
  • Change in the Work Productivity and Activity Impairment questionnaire.

The study is being conducted at 18 centers in Belgium, France, and the Netherlands and is sponsored by the Association de Recherche Clinique en Rhumatologie.
 

AScalate: Treat-to-target in axial spondyloarthritis

The Novartis-sponsored AScalate study seeks to enroll 300 patients with active disease despite NSAID therapy. The 36-week, randomized, parallel-group, open-label, multicenter trial will be conducted at seven sites in Germany.

The study will randomize patients to either of two arms: An active group will receive T2T therapy with secukinumab as a first-line biologic in escalating doses of 150-300 mg, determined by patient response until the T2T goal had been reached. Patients who don’t respond to secukinumab will be switched to an adalimumab biosimilar. The comparator group will receive standard-of-care therapy up to the maximum recommended dose at the discretion of the investigator.

The primary endpoint is the percentage of patients in each group who meet ASAS 40 response criteria by 24 weeks.

There are 11 secondary endpoints, including:

 

 

  • Percentage achieving an ASAS40 response at 12 weeks.
  • Percentage achieving ASAS20 and ASAS partial response at 12 and 24 weeks.
  • Proportion of patients meeting the ASDAS definition of inactive disease, ASDAS clinically important and major improvement, and ASDAS low disease activity.
  • Proportion of patients achieving 50% improvement of the initial BASDAI score.

Consider centralized pain in patients with rheumatic disease

– A fibromyalgia survey may provide important information about the degree to which patients with rheumatic disease experience centralized pain. This information may guide treatment decisions, said Daniel J. Clauw, MD, professor of anesthesiology, rheumatology, and psychiatry and director of the Chronic Pain and Fatigue Research Center at the University of Michigan in Ann Arbor.

Dr. Daniel J. Clauw

The questionnaire that Dr. Clauw uses is a patient self-report survey for the assessment of fibromyalgia based on criteria in the 2011 modification of the American College of Rheumatology preliminary diagnostic criteria for fibromyalgia. In it, he asks patients to report where they experience pain throughout the body and symptoms such as fatigue, sleep problems, and memory problems. The survey predicts outcomes of surgery for osteoarthritis better than x-rays, MRI scans, or psychological factors do, he said.

Physicians should ask every patient with chronic pain, including patients with OA, rheumatoid arthritis, or lupus, to complete the survey, Dr. Clauw said at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education. “This score will tell you the degree to which their central nervous system is augmenting or amplifying what is going on in their body,” he said. “And the higher their score is, the more you should treat them like you would someone with fibromyalgia, even if their underlying disease might be an autoimmune disease.”

Physicians should not use a cutoff of 13 points on the fibromyalgia measure to define whether a patient has the disease, as has been done in the past, he said. The threshold is arbitrary, he said. “We should not think about fibromyalgia as ‘yes’ or ‘no.’ We should think of the degree of fibromyalgia that people have.”
 

A poor relationship between pain and imaging

Some patients who have severe knee OA on imaging walk without pain. Other patients have normal x-rays, but severe pain. “There is a terrible relationship between what you see on a knee x-ray or an MRI and whether someone has pain,” Dr. Clauw said. Furthermore, the poor relationship between imaging and pain is common across chronic pain conditions, he said.

This phenomenon may occur because pain manifests in different ways, similar to there being multiple ways to adjust the volume of an electric guitar, he said. How hard the strings are strummed affects the volume. But so does the amplifier setting. “In these centralized pain conditions, the problem is an amplifier problem, not a guitar problem,” he said. “The amplifier, i.e., the central nervous system, is set too high.”

Researchers have found that people who have severe OA of the knee on x-ray but do not experience pain “have a very low amplifier setting,” he said. That is, they are nontender and less sensitive to pain. Most of these patients are men. “On average, men have a much lower amplifier setting than women,” he said. “This is also why ... women have 1.5 to 2 times the rate of any type of chronic pain than men, because on average women have a higher amplifier setting. ... In OA, at any given age, men and women have the exact same percentage of radiographic OA. But if you look at the clinical condition of OA, it is always two-thirds women, one-third men.”
 

 

 

Opioid responsiveness

To examine whether fibromyalgia survey results correlate with outcomes after knee and hip arthroplasty, Dr. Clauw and colleagues conducted a prospective, observational cohort study that included approximately 500 people. Patients completed the questionnaire on the day of surgery.

Patients with higher levels of fibromyalgia were less responsive to opioids. “For each 1-point increase in the fibromyalgia score, people needed about one more hydrocodone tablet in the first 24-48 hours to control their pain,” he said (Anesthesiology. 2013 Dec;119[6]:1434-43). In addition, each 1-point increase in the fibromyalgia score made people about 25% less likely to have a 50% improvement in knee pain level after 6 months (Arthritis Rheumatol. 2015 May;67[5]:1386-94). The correlations were independent of psychological factors. In addition, the associations were linear. “There was nothing magical about a fibromyalgia score of 13,” Dr. Clauw said.

Dr. Clauw is a coauthor of a study to be presented at the 2019 American College of Rheumatology/Association of Rheumatology Professionals annual meeting that found pain centralization in patients with RA is associated with poor response to disease-modifying antirheumatic drugs (DMARDs).

Prior studies in patients with RA have found that the degree of fibromyalgia is a better predictor of pain and disability than erythrocyte sedimentation rate or the number of swollen joints.
 

Diagnosed cases are the “tip of the iceberg”

Researchers at Dr. Clauw’s institution have identified dozens of patients undergoing knee surgery who met criteria for fibromyalgia but had not received the diagnosis. “This is at the University of Michigan, which is the epicenter for fibromyalgia research. If we are not seeing fibromyalgia superimposed on OA in our patients, no one is seeing it,” he said.

Patients with diagnosed fibromyalgia are “the tip of the iceberg,” he said. “There are far greater numbers of individuals whose primary diagnosis is OA, RA, lupus, ankylosing spondylitis, cancer pain, or sickle cell disease that have the same fundamental problem as fibromyalgia patients. But you do not see it because you label them as having an autoimmune disease or osteoarthritis. And that is at your peril and at their peril. Because treating that individual as if all of their pain and other symptoms are due to a problem out on the periphery will not make that person better.”

Patients with high levels of centralized pain may be less responsive to peripherally directed therapies such as surgery or injections, Dr. Clauw said. Pharmacologic options for patients with centralized pain include gabapentinoids (e.g., pregabalin and gabapentin), serotonin-norepinephrine reuptake inhibitors (e.g., duloxetine and milnacipran), and tricyclic compounds (e.g., amitriptyline and cyclobenzaprine), he said. “Opioids are going to be quite unlikely to help these individuals,” he said. “In fact, it is likely that opioids will make this kind of pain worse.”

Dr. Clauw is a consultant for Aptinyx, Daiichi Sankyo, Eli Lilly, Intec Pharma, Pfizer, Samumed, Theravance, Tonix, and Zynerba Pharma. He has received grant or research support from Aptinyx and Pfizer and is an expert witness.

Secukinumab continues promising axial spondyloarthritis results in PREVENT

Article Type

Mon, 10/07/2019 - 16:49

New results for secukinumab (Cosentyx) in the PREVENT trial continue its promising trend for treatment of the full spectrum of axial spondyloarthritis (axSpA), according to a release from Novartis. The PREVENT trial is assessing this therapy in nonradiographic axSpA (nr-axSpA); it’s already approved in ankylosing spondylitis.

Results of 16-week data were presented in mid-September, and the new results represent 52-week data. Full details and data will be revealed at an upcoming scientific congress.

The PREVENT trial is an ongoing, 2-year trial with a 2-year extension phase; it enrolled 550 men and women with nr-axSpA and assessed their response to secukinumab with an induction phase, to it without induction, or to placebo. The trial met its primary endpoint of 40% improvement in Assessment in Spondyloarthritis International Society (ASAS40) criteria at 16 and 52 weeks, which indicates meaningful and sustained improvement. ASAS40 is defined as an improvement of at least 40% and both 10 out of 100 points in three of four domains (patient global assessment, pain, function, and inflammation) and no worsening in the remaining one. The safety profile in this trial was consistent with those seen in previous trials.

Overall, the most common adverse reactions seen with this interleukin-17A antagonist are nasopharyngitis, diarrhea, and upper respiratory tract infections. Patients should be evaluated for tuberculosis before initiating treatment. Serious infections have been observed, so be mindful of patients with chronic infections and discontinue secukinumab in patients who develop infections. Caution should be exercised when prescribing to patients with inflammatory bowel disease. Full prescribing information can be found on the Novartis website.

Continuous NSAID use for ankylosing spondylitis may raise hypertension risk

Article Type

Fri, 10/04/2019 - 16:05

 

Continuous use of NSAIDs could increase the risk of incident hypertension among patients with ankylosing spondylitis (AS), according to findings from a recent prospective study.

Against expectations, data also suggested that tumor necrosis factor inhibitor (TNFi) therapy could increase blood pressure, although this finding was not significant across all methods of analysis, reported lead author Jean W. Liew, MD, of the University of Washington, Seattle, and colleagues.

The investigators noted that patients with AS already have a greater risk of cardiovascular disease than that of the general population, making any added risks that much more concerning.

“[T]he evidence for increased cardiovascular disease burden and cardiovascular risk in patients with inflammatory rheumatic diseases is well recognized,” the investigators wrote in Arthritis Care & Research. “Multiple population-based studies have demonstrated increased cardiovascular events and cardiovascular-related mortality in AS. There is a high prevalence of cardiovascular risk factors among individuals with AS, particularly hypertension.”

Exacerbation of this risk by NSAIDs has been previously studied with mixed results, according to the investigators. Meta-analyses have suggested that NSAIDs increase blood pressure in normotensive and hypertensive individuals, but some data point to a cardioprotective effect among those with AS, possibly as a consequence of dampened inflammation, and/or improved physical activity, which could lead to a secondary CV benefit. Still, the relationship between NSAIDs and CV risk was unclear, prompting the current study.



The investigators enrolled 1,282 patients with AS at five centers in the United States and Australia. Using a combination of clinical evaluations and self-reporting, enrollees were monitored at regular intervals. Disease activity was tracked with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), while the Bath Ankylosing Spondylitis Functional Index (BASFI) was used for functional impairments. Patients were also checked for a variety of comorbidities such as hypertension, coronary artery disease, mental health conditions, and renal disorders. Medication data included type, dosage, frequency, duration, and number of missed doses.

Including only baseline normotensive patients with at least 1 year of follow-up, 628 participants were eligible for analysis, of whom 200 used NSAIDs continuously. After a median of 7 years follow-up, 129 out of 628 patients developed hypertension. This translated to a hazard ratio (HR) for incident hypertension of 1.12 (95% confidence interval, 1.04-1.20), compared with nonusers or those who took NSAIDs intermittently. This relationship did not differ across subgroups defined by age, disease activity, body mass index, or TNFi use. Multiple sensitivity analyses added support to the association between continuous NSAID use and hypertension.

“The association of NSAIDs and incident hypertension remains particularly concerning, as the early development of hypertension may portend a higher risk of premature CV events due to cumulative exposure,” the investigators wrote.

In contrast with NSAIDs, TNFi therapy was not associated with hypertension across all models; however, against expectations, two models of analysis pointed to an 8% increased risk.



“Although TNFi use did not reach statistical significance in the main model, the direction of association was opposite that hypothesized based on prior data, specifically that TNFi use reduces CV risk by suppressing chronic inflammation,” the investigators wrote.

Considering the present findings, and previous studies, which have reported conflicting associations between TNFi use and hypertension, the investigators suggested that more research is needed, and offered specific methods to approach the topic.

“The association of TNFi use and incident hypertension requires further clarification in future studies,” they wrote, “which may be done by applying a marginal structural modeling (MSM) framework and inverse probability of treatment weighting (IPTW) statistical analyses to account for the relationships between TNFi use, disease activity, and NSAID use.”

In their concluding remarks, the investigators further emphasized the current knowledge gap in this area.

“There is an unmet need to clarify how treatment choices, particularly the use of NSAIDs and TNFi, impact CV risk factors and CV events in AS,” they wrote. “Further studies are needed to focus on precision medicine and predicting risk and benefit for patients in whom continuous NSAIDs are being considered. These further studies can inform the revision of guidelines to address the management of CV risk factors and CV disease in AS and axial spondyloarthritis more broadly.”

The investigators reported funding from the National Institutes of Health, the Assessment of Spondyloarthritis International Society, the Spondylitis Association of America, and the Russel Engleman Rheumatology Research Center at the University of California, San Francisco.

Continuous use of NSAIDs could increase the risk of incident hypertension among patients with ankylosing spondylitis (AS), according to findings from a recent prospective study.

Against expectations, data also suggested that tumor necrosis factor inhibitor (TNFi) therapy could increase blood pressure, although this finding was not significant across all methods of analysis, reported lead author Jean W. Liew, MD, of the University of Washington, Seattle, and colleagues.

The investigators noted that patients with AS already have a greater risk of cardiovascular disease than that of the general population, making any added risks that much more concerning.

“[T]he evidence for increased cardiovascular disease burden and cardiovascular risk in patients with inflammatory rheumatic diseases is well recognized,” the investigators wrote in Arthritis Care & Research. “Multiple population-based studies have demonstrated increased cardiovascular events and cardiovascular-related mortality in AS. There is a high prevalence of cardiovascular risk factors among individuals with AS, particularly hypertension.”

Exacerbation of this risk by NSAIDs has been previously studied with mixed results, according to the investigators. Meta-analyses have suggested that NSAIDs increase blood pressure in normotensive and hypertensive individuals, but some data point to a cardioprotective effect among those with AS, possibly as a consequence of dampened inflammation, and/or improved physical activity, which could lead to a secondary CV benefit. Still, the relationship between NSAIDs and CV risk was unclear, prompting the current study.



The investigators enrolled 1,282 patients with AS at five centers in the United States and Australia. Using a combination of clinical evaluations and self-reporting, enrollees were monitored at regular intervals. Disease activity was tracked with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), while the Bath Ankylosing Spondylitis Functional Index (BASFI) was used for functional impairments. Patients were also checked for a variety of comorbidities such as hypertension, coronary artery disease, mental health conditions, and renal disorders. Medication data included type, dosage, frequency, duration, and number of missed doses.

Including only baseline normotensive patients with at least 1 year of follow-up, 628 participants were eligible for analysis, of whom 200 used NSAIDs continuously. After a median of 7 years follow-up, 129 out of 628 patients developed hypertension. This translated to a hazard ratio (HR) for incident hypertension of 1.12 (95% confidence interval, 1.04-1.20), compared with nonusers or those who took NSAIDs intermittently. This relationship did not differ across subgroups defined by age, disease activity, body mass index, or TNFi use. Multiple sensitivity analyses added support to the association between continuous NSAID use and hypertension.

Collagen metabolites show biomarker potential in axial spondyloarthritis

A new study has found that a group of four collagen metabolites are promising biomarkers for axial spondyloarthritis (axSpA) that could potentially distinguish patients without radiographic signs of disease and those with ankylosing spondylitis.

“This current study illustrates the potential of serological metabolites of tissue destruction as novel disease activity biomarkers in axSpA,” wrote Markéta Hušáková, PhD, of the Institute of Rheumatology and Department of Rheumatology at First Faculty of Medicine Charles University in Prague and coauthors. The study was published in Scientific Reports.

To determine if certain collagen metabolites could indicate axSpA disease activity and distinguish nonradiographic axial spondyloarthritis (nr-axSpA) from ankylosing spondylitis (AS), the researchers examined 193 recently diagnosed axSpA patients and 100 asymptomatic controls. Of the 193 patients, 121 had nr-axSpA and 72 had AS.

The researchers found that four collagen metabolites occurred at significantly higher serum levels in both subtypes of axSpA patients, compared with controls: for C1M, a mean of 43.4 ng/mL for AS and 34.6 ng/mL for nr-axSpA versus 24.5 ng/mL for controls; for C2M, 0.35 and 0.36 versus 0.26; for C3M, 15.4 and 12.8 versus 7.8; and for C4M2, 27.8 and 22.4 versus 15.2. Mean serum levels of C1M, C3M, and C4M2 were significantly higher in AS patients when compared with nr-axSpA patients. Of the four collagen metabolites, C3M was the best for differentiating between axSpA patients and asymptomatic controls (area under receiver operator characteristics curve, 0.95; specificity, 92.0; sensitivity, 83.4) and between nr-axSpA patients and controls (AUC, 0.93; specificity, 80.0; sensitivity, 92.6) and AS patients (AUC, 0.98; specificity, 92.0; sensitivity, 91.7).

The authors acknowledged their study’s limitations, including the inability to investigate changes in biomarker levels and disease activity over time. In addition, there was a lack of clinical information about cardiovascular or other systemic complications, as well as no clinical or radiographic examination of the asymptomatic individuals, which could have revealed factors influencing their metabolite levels.

Two of the authors acknowledged being employees of fibrosis biomarker developer Nordic Bioscience; another researcher acknowledged being a stockholder. No additional conflicts of interest were reported.
