Rituximab raises remission rate in granulomatosis with polyangiitis
More patients with granulomatosis with polyangiitis (GPA) were in remission at 6 months if they had received rituximab (Rituxan) rather than cyclophosphamide (Cytoxan) as induction therapy, according to a target trial emulation performed by the French Vasculitis Study Group (FVSG).
Remission, which was defined as a score of zero on the validated Birmingham Vasculitis Activity Score (BVAS) and use of no more than 10 mg of prednisone a day, was documented in 73.1% of rituximab-treated patients and 40.1% of cyclophosphamide-treated patients.
Similar rates of remission were observed regardless of whether patients were newly diagnosed with GPA (76.1% vs. 41.6%) or had been recently treated for relapsing disease (75.2% vs. 44.5%), FVSG researchers reported in JAMA Network Open.
This research “may inform clinical decision-making regarding the choice of remission-inducing regimen for patients with GPA,” the researchers suggested.
Practice already shifting to rituximab
“The results are largely in line with previous perceptions,” David R.W. Jayne, MD, honorary consultant and director of the vasculitis and lupus service at Addenbrooke’s Hospital in Cambridge, England, observed in an emailed comment.
“The difference is a bit bigger [in favor of rituximab] than I would have expected,” said Dr. Jayne, who is also professor of clinical autoimmunity at the University of Cambridge. He noted that clinical practice was already moving toward using rituximab in place of cyclophosphamide.
Rituximab gained a European license to treat antineutrophil cytoplasmic antibody (ANCA)–associated vasculitides (AAV) just over a decade ago. Since then, it has slowly started to replace the use of cyclophosphamide and glucocorticoids, which were the preferred method up until then.
Part of the reason for this shift is the toxicity associated with cyclophosphamide, although that’s not to say that rituximab is free from safety concerns, Dr. Jayne said.
“Toxicity issues with rituximab, especially secondary immunodeficiency, more severe COVID, and blocking vaccine responses, are becoming bigger issues for day-to-day practice,” he noted. Nonetheless, “the introduction of rituximab has been a revolution in AAV treatment. It has encouraged pharma investment in the disease, such as recent approval of avacopan [Tavneos], and it is helping patients.”
Why simulate and not perform a randomized trial?
There were several reasons for performing the current evaluation, study coauthor Benjamin Terrier, MD, PhD, said in an interview.
“The pivotal study, published in 2010, that led to the approval of rituximab was a noninferiority study in comparison with cyclophosphamide, but it included patients with both GPA, granulomatosis with polyangiitis, and MPA, microscopic polyangiitis,” explained Dr. Terrier, professor of internal medicine at the National Referral Center for Rare Systemic Autoimmune Diseases at Cochin Hospital in Paris.
“A post hoc analysis showed that, in the patients with a PR3 [proteinase 3]-ANCA and in the patients with relapsing disease, rituximab was superior,” he added.
“So, there was some data which suggest that rituximab could be differentially effective between the different subgroups of patients. So that’s why we wanted to answer this question.”
Since it is not always feasible to do a randomized trial, particularly when it concerns a rare disease such as GPA, Dr. Terrier and associates decided to perform a target trial emulation using data from the FVSG registry, which collates information from 32 hospitals in France. Such studies are gaining in popularity and have been shown to provide a very good level of evidence, he said.
Data collections and secondary endpoint results
The researchers obtained data on 194 patients in the registry who were treated for GPA between April 2008 and April 2018. The majority (85.1%) of patients included were newly diagnosed with GPA, and 56.7% were men. The mean age of patients was 54 years.
Information on the PR3-ANCA status of patients was available for 182 patients, and this showed that the majority (80.8%) were positive for this autoantibody.
A weighted analysis was undertaken to iron out any differences in baseline characteristics, such as the fact that more patients had been treated with at least one dose of cyclophosphamide than rituximab (133 vs. 61).
The primary outcome was remission at 6 months, but a key secondary endpoint was the percentage of patients with a BVAS score of zero at this time point. This turned out to be similar among the rituximab- and cyclophosphamide-treated patients (85.5% vs. 82.6%, respectively).
Another secondary endpoint looked at the retention rate without failure at 24 months, with fewer postinclusion treatment failures seen with rituximab than with cyclophosphamide (7 vs. 51 patients, respectively). Most treatment failures were caused by relapses (7 vs. 33).
In terms of safety, the researchers said they found “no increased toxicity signal” for rituximab over cyclophosphamide. In fact, more severe adverse events were noted in the latter group.
Take-home messages
While of course there are limitations, considering the earlier data and the current results, “we probably have enough data to consider that, in the vast majority of GPA patients, in PR3-ANCA patients, rituximab is probably the best option,” Dr. Terrier said.
There are still patients for whom there isn’t a definitive answer on which drug may be best, such as those with severe disease who were not included in the trials or represent few patients in the registry. For them, it is “still a case-by-case discussion, and I think we have to decide really, with caution,” Dr. Terrier said.
What this study also shows is that emulated trials are possible, he added. “I think it shows that we could have some answers to other questions by emulating trials in this rare disease.”
The FVSG registry has received funding from the European Union’s Horizon 2020 research and innovation program. Dr. Terrier reported receiving personal fees from Vifor Pharma Group, GlaxoSmithKline, and AstraZeneca during the conduct of the study. Dr. Jayne has received lecture fees and a research grant from Roche/Genentech.

Sarilumab effective for polymyalgia rheumatica in phase 3 trial
PHILADELPHIA – Treatment with the interleukin-6 receptor antagonist sarilumab (Kevzara), along with a 14-week taper of glucocorticoids, proved to have significant efficacy in patients with relapsing polymyalgia rheumatica (PMR) who were resistant to glucocorticoids in a phase 3 trial.
No new safety concerns were found with sarilumab in the multicenter, randomized, double-blind, placebo-controlled SAPHYR trial. Sarilumab is approved in the United States for the treatment of moderate to severe active rheumatoid arthritis in adults who have had an inadequate response or intolerance to one or more disease-modifying antirheumatic drugs.
The results, presented at the annual meeting of the American College of Rheumatology by Robert Spiera, MD, director of the Scleroderma, Vasculitis, and Myositis Center at the Hospital for Special Surgery in New York, included clinically meaningful improvement in quality-of-life scores.
The disease, which primarily affects people over age 65, can cause widespread aching and stiffness. It’s one of the most common inflammatory diseases among older adults.
PMR is relatively easy to treat with glucocorticoids, but relapses are common, which means long courses of glucocorticoid therapy and the side effects that come with them.
Need for a steroid-sparing therapy
“We recognize that a steroid-sparing drug in polymyalgia rheumatica seems to be an unmet need,” Dr. Spiera said at the meeting.
The trial, sponsored by Sanofi, included active, refractory PMR patients who flared within 3 months of study entry while on at least 7.5 mg/day of prednisone or the equivalent. They were randomly assigned (1:1) to 52 weeks of treatment with subcutaneous sarilumab 200 mg every 2 weeks plus the rapid 14-week glucocorticoid tapering regimen or were given placebo every 2 weeks plus a more traditional 52-week tapering of glucocorticoids.
COVID hampered recruitment
Recruitment was stopped early because of complications during the COVID-19 pandemic, so between October 2018 and July 2020, 118 of the intended 280 patients were recruited, and 117 were treated (sarilumab = 59, placebo = 58). Median age was 69 years in the treatment group and 70 among those taking placebo.
Of the 117 treated, only 78 patients (67%) completed treatment (sarilumab = 42, placebo = 36). The main reasons for stopping treatment were adverse events – including seven with sarilumab and four with placebo – and lack of efficacy (sarilumab = four, placebo = nine).
The primary outcome was the proportion of patients who reached sustained remission at 52 weeks, defined as disease remission by week 12 and no disease flare, normal C-reactive protein (CRP), and adherence to the glucocorticoid taper during weeks 12-52.
The researchers found that sustained remission was significantly higher in the sarilumab arm versus the control group (28.3% versus 10.3%; P = .0193).
IL-6 inhibitors lower CRP, but if you take CRP out of the definition, Dr. Spiera said, “we still saw this difference: 31.7% of patients treated with sarilumab and 13.8% treated with placebo and a longer taper achieved that endpoint.”
Forty-four percent lower risk of flare with sarilumab
Patients in the sarilumab group also had 44% lower risk of having a flare after achieving clinical remission versus the comparator group (16.7% versus 29.3%; hazard ratio, 0.56; 95% confidence interval, 0.35-0.90; P = .0153).
Patient-reported outcomes, which included physical and mental health scores and disability index results, favored sarilumab.
The incidence of treatment-emergent adverse events (TEAEs) was numerically higher in the sarilumab group, compared with the control group (94.9% versus 84.5%). TEAEs included neutropenia (15.3%) and arthralgia (15.3%) in the sarilumab group and insomnia (15.5%) in the comparator arm.
However, the frequency of serious AEs was higher in the control group, compared with the sarilumab arm (20.7% versus 13.6%). No deaths were reported, and, importantly in this age group treated with concurrent glucocorticoids and an IL-6 inhibitor, Dr. Spiera said, “there were no cases of diverticulitis requiring intervention.”
Dr. Spiera was asked about a seemingly low remission rate. He answered that the bar was very high for remission in this study.
Patients had to achieve remission by week 12 and with the rapid 14-week taper. “That means by week 12 the sarilumab arm patients were only on 2 mg of daily prednisone or its equivalent,” he said.
Patients had to maintain that for another 40 weeks, he noted, adding, “I think especially in the context of quality of life and function indices, these were important results.”
Sebastian E. Sattui, MD, director of the University of Pittsburgh Medical Center vasculitis clinic, told this news organization that prolonged use of glucocorticoids in patients with PMR remains an important concern and the need for other options is critical.
“Around 30% of patients with PMR remain on prednisone 5 years after diagnosis,” he said. “Low-dose glucocorticoids are still associated with significant morbidity. Until recently, there has been a paucity of high-quality data regarding the use of steroid-sparing agents in PMR. “
He noted that the SAPHYR trial data are promising “with sarilumab being successful in achieving remission while minimizing glucocorticoids in patients with relapsing PMR.” The clinically meaningful improvement in patient-reported outcomes was just as important, he added.
The main unanswered question is whether the disease-modifying ability of sarilumab will continue after it is stopped, Dr. Sattui said.
Dr. Spiera is a consultant for Sanofi, which funded the trial. He also disclosed financial relationships with GlaxoSmithKline, Boehringer Ingelheim, Corbus, InflaRx, AbbVie/Abbott, Novartis, Chemocentryx, Roche, and Vera. Dr. Sattui has received research support from AstraZeneca and has done unpaid consulting work for Sanofi.

Patient-reported outcomes, which included physical and mental health scores and disability index results, favored sarilumab.
The incidence of treatment-emergent adverse events (TEAEs) was numerically higher in the sarilumab group, compared with the control group (94.9% versus 84.5%). TEAEs included neutropenia (15.3%) and arthralgia (15.3%) in the sarilumab group and insomnia (15.5%) in the comparator arm.
However, the frequency of serious AEs was higher in the control group, compared with the sarilumab arm (20.7% versus 13.6%). No deaths were reported, and, importantly in this age group treated with concurrent glucocorticoids and an IL-6 inhibitor, Dr. Spiera said, “there were no cases of diverticulitis requiring intervention.”
Dr. Spiera was asked about a seemingly low remission rate. He answered that the bar was very high for remission in this study.
Patients had to achieve remission by week 12 and with the rapid 14-week taper. “That means by week 12 the sarilumab arm patients were only on 2 mg of daily prednisone or its equivalent,” he said.
Patients had to maintain that for another 40 weeks, he noted, adding, “I think especially in the context of quality of life and function indices, these were important results.”
Sebastian E. Sattui, MD, director of the University of Pittsburgh Medical Center vasculitis clinic, told this news organization that prolonged use of glucocorticoids in patients with PMR remains an important concern and the need for other options is critical.
“Around 30% of patients with PMR remain on prednisone 5 years after diagnosis,” he said. “Low-dose glucocorticoids are still associated with significant morbidity. Until recently, there has been a paucity of high-quality data regarding the use of steroid-sparing agents in PMR. “
He noted that the SAPHYR trial data are promising “with sarilumab being successful in achieving remission while minimizing glucocorticoids in patients with relapsing PMR.” The clinically meaningful improvement in patient-reported outcomes was just as important, he added.
The main unanswered question is whether the disease-modifying ability of sarilumab will continue after it is stopped, Dr. Sattui said.
Dr. Spiera is a consultant for Sanofi, which funded the trial. He also disclosed financial relationships with GlaxoSmithKline, Boehringer Ingelheim, Corbus, InflaRx, AbbVie/Abbott, Novartis, Chemocentryx, Roche, and Vera. Dr. Sattui has received research support from AstraZeneca and has done unpaid consulting work for Sanofi.

Clinical signs differ between children and adults with vasculitis
Researchers have found a link between age of diagnosis and various clinical characteristics and outcomes in patients with antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV).
The findings, presented at the annual meeting of the American College of Rheumatology, may have implications for research and treatment, especially in children.
AAV is a group of conditions characterized by the development of autoantibodies to the neutrophil proteins proteinase 3 (PR3-ANCA) or myeloperoxidase (MPO-ANCA).
The rare autoimmune condition can cause systemic inflammation and damage, sometimes permanent, to small- and medium-sized arteries. Clinical presentations vary and can include several organs, including skin, stomach, intestines, lung, and kidney, as well as airways in ear, nose, and throat.
Data limited on child vs. adult characteristics
AAV can be diagnosed in any decade of life, but clinical characteristics and outcomes often differ between children and adults, and data are limited. Studies often exclude children.
Lead author Jessica Bloom, MD, MSCS, a pediatric rheumatologist and assistant professor of pediatrics at Children’s Hospital Colorado, Aurora, and colleagues performed an analysis of patients with granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) who were enrolled in the Vasculitis Clinical Research Consortium Longitudinal Studies from 2013 to 2021.
Patients with eosinophilic GPA (EGPA) were analyzed separately. Children and young adults with EGPA were combined because of the small sample size (n = 87).
The groups were sorted by the age they were diagnosed: under 18 years old, 18-40, 40-65, and older than 65.
More than 1,000 patients included
Dr. Bloom’s team analyzed data from 1,020 patients: 61 diagnosed as children, 240 as young adults, 560 as middle-aged adults, and 159 diagnosed as older adults. At all ages, about nine out of 10 patients were White.
They found 852 (84%) had GPA and 165 (16%) had MPA. The analysis also showed 893 (92%) of patients with ANCA results were ANCA positive: 637 (65%) with PR3-ANCA, 247 (25%) with MPO-ANCA, and 9 (1%) with both.
Differences between age groups included:
- Children experienced more subglottic stenosis and alveolar hemorrhage than adults with the condition.
- About half of patients diagnosed in childhood received both cyclophosphamide and rituximab. That rate decreased with increasing age of diagnosis to as low as 14% for those diagnosed in older adulthood.
- More females than males in all age groups were diagnosed with AAV, but the difference was most pronounced when diagnosed in childhood, and female predominance declined as age increased.
- Older adults experienced more neurologic disease and less musculoskeletal and sinus involvement.
Additionally, for those diagnosed after age 65, after adjusting for disease length and whether they were taking cyclophosphamide and/or rituximab, the Vasculitis Damage Index (VDI) and ANCA Vasculitis Index of Damage (AVID) scores were higher than for those diagnosed in childhood.
“However, these differences are no longer significant when medication toxicity and comorbidity-related items are excluded. Thus, differences in the VDI and AVID scores are driven by non–disease-specific damage,” Dr. Bloom said.
Bringing children into the clinical discussion
Dr. Bloom said in an interview that
For example, the findings that children have more subglottic stenosis and alveolar hemorrhage than adults “may warrant more aggressive therapy,” she said. Children also have different growth and psychosocial risk factors during their disease course and may live longer with the disease than those in older age groups.
“Our study helps to point out these differences and bring children into the discussion,” Dr. Bloom said. “It also recognizes that damage scores used in studies and care may not adequately assess disease across the lifespan, as they are largely influenced by items not specific to the disease but rather medication toxicity and comorbidities, such as osteoporosis, cataracts, and malignancy.”
Robert Spiera, MD, director of the Scleroderma, Vasculitis, and Myositis Center at Hospital for Special Surgery, New York, said in an interview that the work highlights interesting information about the fact that disease features are skewed differently in children – “in particular the higher likelihood of upper airway [subglottic] disease, and potentially severe lower airway disease [alveolar hemorrhage].”
However, from a practical standpoint, Dr. Spiera said, “I am not sure that this will change our clinical approach to different patients, but the differences in disease features and even the sex differences in terms of who are afflicted with GPA [more often children and more likely to be female] may offer insights into disease pathogenesis.”
Dr. Bloom received funding from the Vasculitis Clinical Research Consortium and Vasculitis Foundation to conduct this work as a VCRC-VF fellow. Several coauthors reported various conflicts of interest with pharmaceutical companies. Dr. Spiera declared no relevant financial relationships.

FROM ACR 2022
Updated EULAR recommendations for AAV include new drugs, practices
The
The 2022 revision – which was unveiled at the annual European Congress of Rheumatology – includes guidance on using new drugs, such as avacopan (Tavneos) and mepolizumab (Nucala), as well as revised recommendations on the use of rituximab and glucocorticosteroids.
The overhaul also contains specific recommendations for treating eosinophilic granulomatosis with polyangiitis (EGPA), separating it out from granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) for the first time.
“Until now, EGPA has usually been managed in the same way as [the] other diseases,” Bernhard Hellmich, MD, of the University of Tübingen (Germany) said in an interview ahead of his presentation at the congress.
“But we now have data on each type specifically, so there is good reason to make separate recommendations,” he added.
Indeed, so much new data has become available in the past few years there are only three recommendations that remain unchanged from the previous iteration published in 2016.
Since then, “several high-impact studies in AAV have been published and the results of these studies required an update of the existing recommendations,” Dr. Hellmich said.
Developed in record time – just 7 months from start to finish – the process of updating the recommendations on AAV followed EULAR’s standard operating procedures. An important step in this process is to perform a systemic literature review. Perhaps crucially, and in contrast to the first U.S. vasculitis guidelines published only in 2021, the most recent literature search was able to include data on avacopan, which was approved for use in Europe in January as an adjunctive treatment for adults with severe active GPA and MPA.
The results of the literature review were reported separately at the EULAR 2022 Congress, with separate presentations highlighting the data behind the amended treatment and diagnostic and follow-up procedure recommendations.
Highlights of the changes
A key change is the introduction of four overarching principles, which weren’t included in the previous update, said Dr. Hellmich.
“We moved some of the existing recommendations with low level of evidence to overarching principles,” he added, stating that the first general principle was that all patients should be offered “the best care which must be based on shared decision-making between the patient and the physician considering efficacy, safety, and costs.”
The second principle states that patients should have access to education that covers the prognosis and impact of AAV, including recognizing warning symptoms and treatment options.
The third focuses on screening for adverse effects and comorbidities, recommending that patients are given appropriate prophylaxis and lifestyle advice.
Finally, the fourth general principle recognizes that AAV is a rare group of heterogenous and potentially life-threatening diseases that need multidisciplinary care, with access to specific vasculitis expertise.
New recommendations
Of the 17 recommendations made, 6 are completely new, including one on ANCA testing in patients who are suspected of having AAV.
“We recommend testing for both PR3- and MPO-ANCA using a high-quality antigen-specific assay as the primary method of testing,” Dr. Hellmich said. This is based on strong new evidence that antigen-specific assays have superior diagnostic accuracy, compared with indirect immunofluorescence.
“We also want to emphasize that ANCA testing should be done in patients with signs and symptoms in order to minimize the risk of false-positive results,” Dr. Hellmich said.
Also new is the recommendation to use oral steroids to induce remission in GPA/MPA, followed by a stepwise reduction in the dose, aiming for a dose of not more than 5 mg prednisolone per day by 4-5 months of treatment.
“Glucocorticoids are very effective, but also are the major trigger of infections in AAV,” said Dr. Hellmich. This is important since infections are a major driver of early mortality in AAV.
“Another possibility to reduce glucocorticoid exposure is avacopan,” he said. It’s recommended to be used in combination with rituximab or cyclophosphamide for remission induction in GPA/MPA as a strategy to basically “get rid of steroids.”
Indeed, “for patients who really have a high burden of glucocorticoid-associated adverse effects, especially relapsing patients, I think it would make sense just to give avacopan and no steroids,” Dr. Hellmich said.
Other new recommendations concern remission induction and maintenance therapy in new-onset EGPA. Regarding the latter, the choice of treatment depends on whether there is an organ- or life-threatening situation, with methotrexate, azathioprine, mepolizumab, or rituximab all recommended equally, or if there is no organ- or life-threatening situation, then mepolizumab is preferred.
Revised and unchanged recommendations
Eight of the recommendations have been revised, with rituximab being placed more prominently as a treatment in some. For remission induction in GPA and MPA with organ- or life threatening disease, rituximab is now the preferred option for relapsing disease. Rituximab also replaced methotrexate as the preferred option for maintaining remission, although methotrexate and azathioprine can still be considered as alternatives.
Another changed statement is on the duration of maintenance treatment in GPA and MPA, which now advocates 1-2 years of treatment after achieving remission. Longer therapy might be needed in relapsing cases, but the benefits and risks need to be carefully considered and patient preferences taken into account.
Prophylaxis against pneumonia and other infections is still recommended, with the revised guidance noting that patients receiving cyclophosphamide, rituximab, or high-dose steroids, should be treated with trimethoprim-sulfamethoxazole (co-trimoxazole).
“There are retrospective data in the AAV population that the administration of co-trimoxazole reduces not only the incidence of pneumocystis, but also of other infections. So, this is important recommendation for clinical practice,” Dr. Hellmich said.
Summing up
“For a rare disease group, I think this is very good progress,” said Dr. Hellmich, but “there are still many open questions, so we have a long research agenda.”
There is purposefully no recommendation on COVID-19, however, as “the conditions that impact COVID outcomes change rapidly and any recommendation made now is likely to be outdated soon; the AAV recommendations are intended to last for at least a couple of years.”
In a press release issued by the German Society for Rheumatology, which was unrelated to Dr. Hellmich’s talk, experts commented on vasculitis guidelines generally, noting that there has been a move toward using biologic therapies such as rituximab and mepolizumab as a new standard of therapy.
DGRh President and chief physician at the Immanuel Hospital in Berlin Andreas Krause, MD, observed that “cyclophosphamide, which was used in the past and which inhibits blood formation in the bone marrow and can lead to infertility, can now often be dispensed with.”
Julia Holle, MD, of Rheumazentrum Schleswig-Holstein Mitte in Neumünster, Germany, was also quoted in the press release, saying that, “for patients, the successful use of biologics and the reduction in the glucocorticoid dose is important progress.”
Dr. Holle was involved in the development of revised European guidelines. She is also the lead author of a recent publication on treatment of vasculitis on available evidence. Dr. Hellmich acknowledged having ties to multiple pharma companies, acting as speaker, consultant, or both to Abbvie, Amgen, AstraZeneca, Boehringer Ingelheim, Bristol-Myers Squibb, Chugai, GlaxoSmithKline, InflaRx, Merck Sharp & Dohme, Novartis, Pfizer, Roche, and Vifor.

Of the 17 recommendations made, 6 are completely new, including one on ANCA testing in patients who are suspected of having AAV.
“We recommend testing for both PR3- and MPO-ANCA using a high-quality antigen-specific assay as the primary method of testing,” Dr. Hellmich said. This is based on strong new evidence that antigen-specific assays have superior diagnostic accuracy, compared with indirect immunofluorescence.
“We also want to emphasize that ANCA testing should be done in patients with signs and symptoms in order to minimize the risk of false-positive results,” Dr. Hellmich said.
Also new is the recommendation to use oral steroids to induce remission in GPA/MPA, followed by a stepwise reduction in the dose, aiming for a dose of not more than 5 mg prednisolone per day by 4-5 months of treatment.
“Glucocorticoids are very effective, but also are the major trigger of infections in AAV,” said Dr. Hellmich. This is important since infections are a major driver of early mortality in AAV.
“Another possibility to reduce glucocorticoid exposure is avacopan,” he said. It’s recommended to be used in combination with rituximab or cyclophosphamide for remission induction in GPA/MPA as a strategy to basically “get rid of steroids.”
Indeed, “for patients who really have a high burden of glucocorticoid-associated adverse effects, especially relapsing patients, I think it would make sense just to give avacopan and no steroids,” Dr. Hellmich said.
Other new recommendations concern remission induction and maintenance therapy in new-onset EGPA. Regarding the latter, the choice of treatment depends on whether there is an organ- or life-threatening situation, with methotrexate, azathioprine, mepolizumab, or rituximab all recommended equally, or if there is no organ- or life-threatening situation, then mepolizumab is preferred.
Revised and unchanged recommendations
Eight of the recommendations have been revised, with rituximab being placed more prominently as a treatment in some. For remission induction in GPA and MPA with organ- or life threatening disease, rituximab is now the preferred option for relapsing disease. Rituximab also replaced methotrexate as the preferred option for maintaining remission, although methotrexate and azathioprine can still be considered as alternatives.
Another changed statement is on the duration of maintenance treatment in GPA and MPA, which now advocates 1-2 years of treatment after achieving remission. Longer therapy might be needed in relapsing cases, but the benefits and risks need to be carefully considered and patient preferences taken into account.
Prophylaxis against pneumonia and other infections is still recommended, with the revised guidance noting that patients receiving cyclophosphamide, rituximab, or high-dose steroids, should be treated with trimethoprim-sulfamethoxazole (co-trimoxazole).
“There are retrospective data in the AAV population that the administration of co-trimoxazole reduces not only the incidence of pneumocystis, but also of other infections. So, this is important recommendation for clinical practice,” Dr. Hellmich said.
Summing up
“For a rare disease group, I think this is very good progress,” said Dr. Hellmich, but “there are still many open questions, so we have a long research agenda.”
There is purposefully no recommendation on COVID-19, however, as “the conditions that impact COVID outcomes change rapidly and any recommendation made now is likely to be outdated soon; the AAV recommendations are intended to last for at least a couple of years.”
In a press release issued by the German Society for Rheumatology, which was unrelated to Dr. Hellmich’s talk, experts commented on vasculitis guidelines generally, noting that there has been a move toward using biologic therapies such as rituximab and mepolizumab as a new standard of therapy.
DGRh President and chief physician at the Immanuel Hospital in Berlin Andreas Krause, MD, observed that “cyclophosphamide, which was used in the past and which inhibits blood formation in the bone marrow and can lead to infertility, can now often be dispensed with.”
Julia Holle, MD, of Rheumazentrum Schleswig-Holstein Mitte in Neumünster, Germany, was also quoted in the press release, saying that, “for patients, the successful use of biologics and the reduction in the glucocorticoid dose is important progress.”
Dr. Holle was involved in the development of revised European guidelines. She is also the lead author of a recent publication on treatment of vasculitis on available evidence. Dr. Hellmich acknowledged having ties to multiple pharma companies, acting as speaker, consultant, or both to Abbvie, Amgen, AstraZeneca, Boehringer Ingelheim, Bristol-Myers Squibb, Chugai, GlaxoSmithKline, InflaRx, Merck Sharp & Dohme, Novartis, Pfizer, Roche, and Vifor.
