Upadacitinib doubles ASAS 40 response vs. placebo in ankylosing spondylitis
ATLANTA – in the randomized, placebo-controlled, phase 2/3 SELECT-AXIS 1 study.
Physical functioning and imaging measures also were improved with upadacitinib in the double-blind, multicenter study, Désirée van der Heijde, MD, PhD, reported at the annual meeting of the American College of Rheumatology.
The findings are notable because patients with ankylosing spondylitis (AS) who have an inadequate response or contraindication to NSAIDs have limited treatment options other than biologic disease-modifying antirheumatic drugs (bDMARDs). The JAK pathway has emerged as a potential therapeutic target in AS, and given its recent approval for the treatment of RA as well as ongoing studies of the agent for several other chronic immune-mediated inflammatory diseases, Dr. van der Heijde and colleagues sought to assess its efficacy and safety in bDMARD-naive patients with active AS.
Of 93 AS patients aged 18 years and older who were randomized to receive 15 mg of upadacitinib daily, 51.6% achieved the primary study endpoint of 40% improvement in Assessment of Spondyloarthritis International Society response criteria (ASAS 40) at week 14, compared with 25.5% of 94 patients who received placebo, said Dr. van der Heijde, professor of rheumatology at Leiden (the Netherlands) University Medical Center.
The effect was rapid, with a clear difference emerging between the treatment and placebo groups within 2 weeks, she noted.
Significant improvements were also seen with upadacitinib for several key secondary endpoints including change from baseline to week 14 in the Ankylosing Spondylitis Disease Activity Score, Spondyloarthritis Research Consortium of Canada MRI Spine, a 50% improvement of the initial Bath Ankylosing Spondylitis Disease Activity Index (BASDAI 50), ASAS partial remission, and Bath Ankylosing Spondylitis Functional Index.
SELECT-AXIS 1 patients were adults with a mean age of 45 years who were enrolled from 60 sites in 20 countries. All met modified New York criteria for AS based on central reading of radiographs, had a BASDAI score of at least 4, had a patient assessment of total back pain of 4 or greater on a 0-10 scale at screening and baseline, were naive to bDMARDs, and had either an inadequate response to at least two NSAIDs or an intolerance/contraindication to NSAIDs.
Most patients (70.6%) were men, and 76.5% were HLA-B27 positive. Mean symptom duration was 14-15 years, and mean disease duration was 7-8 years, Dr. van der Heijde said, adding that baseline disease characteristics were balanced between the two arms.
All randomized patients received their assigned treatment, and 95.7% completed the study through week 14, including 90 of 94 placebo group patients and 89 of 93 upadacitinib patients.
“Treatment was generally well tolerated,” she said.
The proportions of patients in the treatment and placebo groups, respectively, were similar with respect to adverse events leading to discontinuation (2.2% vs. 3.2%), serious adverse events (1.1% in each group), and infections (20.4% vs. 27.7%). No serious infections, herpes zoster, malignancy, venous thromboembolic events, or deaths were reported. Also, no differences were seen between the groups in relevant laboratory abnormalities, and no new safety finding were observed in comparison with previous upadacitinib studies in other diseases, she noted.
Dr. van der Heijde concluded that “these results support further investigation of upadacitinib for the treatment of ankylosing spondyloarthritis.”
AbbVie, which markets upadacitinib, funded the study. Dr. van der Heijde disclosed financial relationships with AbbVie and 20 other pharmaceutical companies. Many other authors also reported financial relationships with industry, including AbbVie.

REPORTING FROM ACR 2019
Certolizumab safety profile varies widely across indications
MADRID – , Andrew Blauvelt, MD, reported at the annual congress of the European Academy of Dermatology and Venereology.
He presented a comprehensive analysis of safety data from all 49 clinical trials of the tumor necrosis factor inhibitor for its approved indications. The data set included 11,317 patients who received certolizumab for a collective 21,695 person-years in 27 trials in rheumatoid arthritis patients, 5 in psoriasis, 15 for Crohn’s disease, and one trial each for axial spondyloarthritis and psoriatic arthritis.
“It’s not real-world data, but it is a large group of patients [studied] over many years,” noted Dr. Blauvelt, a dermatologist and president of the Oregon Medical Research Center, Portland.
As a renowned authority on psoriasis, he was part of a multidisciplinary expert panel commissioned by UCB to analyze serious adverse events in the complete clinical trials experience involving the company’s tumor necrosis factor inhibitor certolizumab (Cimzia). The panel included experts from rheumatology, gastroenterology, epidemiology, and other disciplines.
The key takeaway: “When you think about the serious side effects of the drug, you have to think about what the indication is, whether the patients are on systemic corticosteroids, and whether they’re heavy or not,” Dr. Blauvelt said.
Take, for example, the risk of serious infections requiring treatment with intravenous antibiotics. The incidence rates ranged from a low of 1.5 per 100 patient-years in psoriasis patients on certolizumab to a high of 5.97 in those with Crohn’s disease, with rates of 3.44 cases per 100 patient-years among rheumatoid arthritis patients and 1.64-1.67 in those with psoriatic arthritis and ankylosing spondylitis, respectively. Patients with Crohn’s disease were 2.22-fold more likely than were those with rheumatoid arthritis to experience a serious infection during their clinical trial experience on certolizumab. In contrast, psoriasis patients had a 52% relative risk reduction and those with psoriatic arthritis were 31% less likely to develop a serious infection compared with those with rheumatoid arthritis.
The explanation for these highly variable serious infection rates lies in part on the huge differences in the concurrent use of systemic corticosteroids with certolizumab across indications. A mere 3.3% of psoriasis patients were also on steroids, compared with 46.2% of rheumatoid arthritis patients, 50.8% of those with ankylosing spondylitis, and about 25% of the Crohn’s disease and psoriatic arthritis patients, he noted.
Advanced age was independently associated with increased risk of serious infections. Patients aged 65 or older were 1.68-fold more likely to experience this event than were those under age 45. And patients whose disease duration was 10 years or more at baseline had a 1.36-fold increased serious infection risk compared with those who had less than a 1-year-long disease history, independent of which disease they had.
The prevalence of baseline obesity varied by indication. The mean body mass index was 30.1 kg/m2 in the psoriasis patients, 29.8 kg/m2 in those with psoriatic arthritis, lowest at 24 kg/m2 in Crohn’s disease patients, and a bit over 27 kg/m2 in those with rheumatoid arthritis or ankylosing spondylitis.
Obesity alone was not an independent risk factor for serious infection in certolizumab-treated patients; however, the combination of a BMI of 30 kg/m2 or more plus systemic corticosteroid use was associated with a greater risk than with steroids alone.
Based upon a multivariate regression analysis adjusted for age, sex, indication, disease duration, use of methotrexate, and prior use of other TNF inhibitors, the investigators calculated that in patients with Crohn’s disease 16.6% of serious infections in patients on certolizumab were attributable to systemic corticosteroid use.
Risks of major adverse cardiovascular events and cancer on certolizumab
The risk of major adverse cardiovascular events (MACE) while on certolizumab ranged from a high of 0.62 MACE events per 100 patient-years in the rheumatoid arthritis population to a low of 0.1 per 100 patient-years in patients treated for Crohn’s disease or ankylosing spondylitis. Psoriasis and psoriatic arthritis patients had MACE rates of 0.27 and 0.54, respectively.
Obesity was independently associated with increased risk of an acute MI and other MACEs. So was advanced age. No surprises there. The investigators calculated that 16.7% of MACEs in patients on certolizumab were attributable to obesity and another 20.9% were attributable to use of systemic corticosteroids.
The incidence rate for all malignancies, including nonmelanoma skin cancer, ranged from a low of 0.46 cases per 100 patient-years in the psoriatic arthritis cohort on certolizumab to a high of 0.93 in those with rheumatoid arthritis, with rates of 0.68, 0.73, and 0.51 in patients with psoriasis, Crohn’s disease, and ankylosing spondylitis, respectively.
Neither systemic corticosteroids, obesity, disease duration, or prior exposure to a TNF inhibitor was linked to increased risk of cancer in patients on certolizumab. The standout risk factor was age: Patients who were 65 or older at baseline were 11.4-fold more likely to develop cancer during participation in their clinical trial than were those younger than 45. Those who were 45 to 65 years old were 4.3-fold more likely to be diagnosed with a malignancy than were those younger than age 45.
Of note, concomitant use of methotrexate was associated with a statistically significant 28% reduction in malignancy risk.
Dr. Blauvelt reported serving as a consultant to and receiving research funding from UCB, the study sponsor, as well as more than two dozen other pharmaceutical companies.

REPORTING FROM THE EADV CONGRESS
More studies like VERVE needed to test live vaccines in special populations
The VERVE study highlights a crucial topic for rheumatologists treating patients in clinical practice. The traditional thinking is to inform patients never to receive live vaccines when they are using TNF (tumor necrosis factor) inhibitors to treat their autoimmune disease. The VERVE study indicates that in the case of the Zostavax vaccine, patients on this form of biologic therapy for rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis can safely receive this preventive measure. This study scratches the surface on an important topic, and other studies need to follow.
Many patients on biologic therapy want to travel. Many times, international travel requires vaccination that is only in the form of a live vaccine – for example, the yellow fever vaccine. It would be useful for us to better understand whether other live vaccines can safely be administered and better inform our patients who want to travel. In addition, many times mothers with young infants are nervous if they are on biologic therapy and their children need to receive a live vaccine. They are concerned that their children will shed the live virus and they will be in jeopardy. This study highlights that this may be more of an antiquated way of thinking. We need more studies of this kind to better understand and advise our patients properly without instilling unwarranted fear.

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

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

REPORTING FROM ACR 2019
FDA announces approval of fifth adalimumab biosimilar, Abrilada
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.
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
ATLANTA – 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.
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.

ATLANTA – 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.
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).

REPORTING FROM ACR 2019
Spinal progression found more often in men with ankylosing spondylitis
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
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.
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.

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.
Consider centralized pain in patients with rheumatic disease
Las Vegas – 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.
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.”
