Combination therapy may boost remission in JIA
Benefit endures at 3 years
PHILADELPHIA – Aggressive therapy using conventional synthetic disease-modifying antirheumatic drugs (DMARDs) in combination with biologic agents early, soon after a child is diagnosed with polyarticular juvenile idiopathic arthritis (pJIA), enabled more patients to achieve clinical remission and longer times in inactive disease than more conventional therapeutic approaches, 3-year results of prospective, observational study demonstrated.
The results of The Childhood Arthritis and Rheumatology Research Alliance STOP-JIA study, which Yukiko Kimura, MD, presented at the annual meeting of the American College of Rheumatology, showed early combination therapy had benefits, compared with other treatment strategies that were more evident at 3 years than at 1 year of study.
“The STOP-JIA study showed that, after 3 years, patients who started a biologic early on in combination with methotrexate spent more time in inactive disease and achieved clinical remission more often when compared to those started on traditional step-up therapy,” Dr. Kimura, chief of pediatric rheumatology at Hackensack (N.J.) Meridian Health and professor of pediatrics at the Hackensack Meridian School of Medicine, said at a press conference. “This study shows that the treatment of poly-JIA patients receive initially very early on in their disease matters even 3 years after that treatment was started.”
The study compared three CARRA consensus treatment plans (CTP) for untreated pediatric pJIA patients: step-up (SU) – starting conventional synthetic DMARD therapy and adding a biologic if needed after 3 or more months; early-combination (EC) therapy – starting synthetic and biologic DMARDs together; and biologic first (BF) therapy – starting biologic DMARD monotherapy.
Dr. Kimura explained the rationale for the study. “Since biologic treatments were introduced more than 20 years ago, the prognosis for JIA significantly improved. These very effective medicines often work wonders, quickly reducing pain and inflammation in joint disease activity,” she said in the press conference. “What is not known, however, is when is the best time to start these very effective treatments.”
The most common approach is to start with a synthetic DMARD, typically methotrexate, and wait before starting a biologic, Dr. Kimura said.
“But even though methotrexate can work very well by itself, it does not work for every patient, and we don’t know whether waiting months for it to work and then starting a biologic might potentially lessen their effectiveness,” Dr. Kimura added. “We don’t know if there’s a window of opportunity that’s lost while waiting to see whether methotrexate will work.”
The study originally enrolled 400 patients, 297 of whom completed the 3-year visit – 190 in SU, 76 in EC and 31 in BF. At 12 months, the study found no statistically significant difference in clinically inactive disease (CID) between the groups, Dr. Kimura said.
Even at the 3-year visit, the percentage of patients in CID off glucocorticoids and clinical Juvenile Arthritis Disease Activity Score based on 10 joints inactive disease (cJADAS 10 ID) did not differ among the three groups, Dr. Kimura said in presenting the results. “But,” she added, “greater proportions of early-combination CTP group were able to achieve clinical remissions and spend more time with inactive disease in both CID and cJADAS 10.”
A closer look at the outcomes showed some separation between early-combination therapy and the other two treatment plans. The incidence of clinical remission (at any time point over 36 months) was 67.1% in the EC group vs. 49.1% and 47.3%, respectively, in the BF and SU groups, Dr. Kimura said. “The difference between the early-combination and step-up groups was highly significant [P = .007],” she added.
EC also had an edge in the percentage of time patients spent in CID (over 36 months): 39.2% versus 32% and 27.4%, respectively, in the BF and SU groups (P = .006 for EV vs. SU), as well as cJADAS 10 ID (50.6% in EC group vs. 42.8% and 37.5%, respectively in the BF and SU groups; P = .005 for EC vs. SU).
Dr. Kimura said that the STOP JIA trial will continue with longer-term analysis and ongoing monitoring of study patients through the CARRA registry. “These longer-term analyses and readouts will be important because even though the results at 12 months didn’t seem as definitive, it seems the longer we go, the more impact we see of the treatments that were started early on in this disease.”
The findings from this study are “significantly important,” Nina T. Washington, MD, MPH, a pediatric rheumatologist at the University of New Mexico Hospital, Albuquerque, and the Mary Bridge Children’s Hospital in Tacoma, Wash., said in an interview. “At least for the past decade we’ve really been advocating towards earlier and aggressive therapy, and that’s what this study shows: the sooner you can treat this disease, the sooner you can attack those joints that are inflamed, the better outcome you give the patient.”
The study also confirms that pediatric rheumatologists are not overtreating patients with pJIA, she added.
“In a sense we’re actually treating and preventing and if you have a child that has arthritis, it’s okay to treat that child,” Dr. Washington said. “For me that’s the most reassuring thing: that I’m not necessarily going overboard. If I have a child with polyarticular JIA and they have multiple inflamed joints and I have the evidence as they’re sitting in front of me, and I treat them. I’m going to give them the best outcome.”
The Patient Centered Outcomes Research Institute provided study funding. Dr. Kimura is chair of the CARRA JIA disease research committee and cochair of the CARRA Registry and Research Oversight Committee. She disclosed a financial relationship with Genentech. Dr. Washington has no relevant relationships to disclose.

Infant anaphylaxis: Study characterizes symptoms, treatment
LOUISVILLE, KY. – , research findings indicate.
Given that early administration of epinephrine can be potentially lifesaving for infants with anaphylaxis, the study highlighted the real-world successes in increased uptake of treatment in this vulnerable patient population.
Most infants in the study who presented to the ED and received epinephrine were able to be discharged home after just a few hours, with only 1 out of 10 requiring hospitalization.
The study also reported that most symptoms were in the skin/mucosal, gastrointestinal, respiratory, and cardiovascular (CV) systems, providing improved characterization of anaphylaxis symptoms in the infant population.
Nearly “all episodes were triggered by food – especially egg, peanut, milk, and cashew,” commented Colleen Shannon, MD, a pediatrician at Children’s Hospital of Philadelphia, who presented the research findings at the annual meeting of the American College of Allergy, Asthma, and Immunology.
Dr. Shannon noted that despite previous research demonstrating age-based differences in the presentation of anaphylaxis, the symptomatology of anaphylaxis in infants has not been robustly characterized. Better characterization of anaphylaxis in infants with allergies may help ensure earlier and more accurate diagnosis and management, she said.
For the study, the researchers performed a retrospective chart review of 169 patients between 0 and 24 months of age (mean age, 1.0 years) who presented to the emergency department of a pediatric tertiary referral center between 2019 and 2022.
All patients in the study met diagnostic criteria for anaphylaxis. The investigators used the medical records of patients to evaluate for demographics, as well as presenting symptoms and treatment.
More than half (56.2%) of infants in the study were 12 months of age or younger, and 64.5% were male.
Nearly all (96.5%) anaphylaxis episodes presenting to the ED were triggered by food. The most common foods triggering these episodes were egg (26.6%), peanut (25.4%), milk (13.6%), and cashew (10.1%).
Most symptoms involved the skin/mucosal (97.6%) and GI (74.6%) systems, followed by respiratory (56.8%) and CV (34.3%) systems. Isolated tachycardia was recorded in 84.5% of patients with CV-related symptoms.
Epinephrine was administered to 86.4% of infants who presented to the ED with anaphylaxis. Nearly a third (30.1%) of these infants received epinephrine before arriving to the ED, and 9.5% required more than 1 dose.
The researchers also found that 10.1% of patients required hospital admission, but none had symptoms severe enough to require intensive care.
Jennifer Hoffmann, MD, an emergency medicine physician at the Lurie Children’s Hospital of Chicago, told this news organization that while characterizing anaphylaxis symptoms is relevant for clinicians, it also remains vitally important “to teach parents of infants how to recognize the signs of anaphylaxis, particularly as they begin to introduce new foods,” to ensure timely treatment.
She added that since most infants in the study improved after a single dose of epinephrine, most infants presenting to the ED with anaphylaxis can therefore be safely discharged home after only a brief period of observation. “That is, age alone should not be a reason for admission,” explained Dr. Hoffmann, who wasn’t involved in the research study.
The study was independently supported. Dr. Shannon and Dr. Hoffmann report no relevant financial relationships.

Tirzepatide cuts BP during obesity treatment
CHICAGO – compared with placebo, while causing modest increases in heart rate, in a prespecified substudy of the SURMOUNT-1 trial.
“The large effects on ambulatory 24-hour blood pressure raise the possibility that there may be important long-term benefits of [tirzepatide] on the complications of obesity,” said James A. de Lemos, MD, during a presentation at the American Heart Association scientific sessions.
“The findings are concordant with the [previously reported] office-based measurements, and the blood pressure reductions provide further evidence for the potential benefits of tirzepatide on cardiovascular health and outcomes,” said Dr. de Lemos, a cardiologist and professor at the University of Texas Southwestern Medical Center, Dallas.
The substudy included 600 of the 2,539 people enrolled in SURMOUNT-1, the first of two pivotal trials for tirzepatide (Mounjaro) in people without diabetes but with obesity or overweight (body mass index of 27-29 kg/m2) plus at least one weight-related complication. The primary endpoints of SURMOUNT-1 were the percent change in weight from baseline to 72 weeks on treatment with either of three different weekly injected doses of tirzepatide, compared with control subjects who received placebo, and the percentage of enrolled subjects achieving at least 5% loss in baseline weight, compared with the controls.
Tirzepatide treatment led to significant increases in both results, compared with controls, with the highest dose tested, 15 mg/week, resulting in an average 20.9% drop in weight from baseline after 72 weeks of treatment, and 91% of enrolled subjects on that dose achieving the 5% weight-loss threshold during the same time frame, in results published in 2022 in the New England Journal of Medicine.
24-hour ambulatory pressures from 494 people
The substudy enrolled 600 of the SURMOUNT-1 participants and involved 24-hour ambulatory BP and heart rate measurements at entry and after 36 weeks on treatment. Full results were available for 494 of these people. The substudy included only study participants who entered with a BP of less than 140/90 mm Hg. Enrollment in SURMOUNT-1 overall excluded people with a BP of 160/100 mm Hg or higher. The average BP among all enrolled participants was about 123/80 mm Hg, while heart rates averaged about 73 beats per minute.
Systolic BP measured with the ambulatory monitor fell from baseline by an average of 5.6, 8.8, and 6.2 mm Hg in the people who received tirzepatide in weekly doses of 5, 10, or 15 mg, respectively, and rose by an average 1.8 mm Hg among the controls, Dr. de Lemos reported. Diastolic BP dropped among the tirzepatide recipients by an average of 1.5, 2.4, and 0.0 mm Hg in the three ascending tirzepatide treatment arms, and rose by an average 0.5 mm Hg among the controls. All of the differences between the intervention groups and the controls were significant except for the change in diastolic BP among participants who received 15 mg of tirzepatide weekly.
The results showed that 36 weeks on tirzepatide treatment was associated with “arguably clinically meaningful” reductions in systolic and diastolic BPs, Dr. de Lemos said. “There is a lot of optimism that this will translate into clinical benefits.” He also noted that, “within the limits of cross-study comparisons, the blood pressure changes look favorable, compared with the single-incretin mechanism GLP-1 [glucagonlike peptide–1] receptor agonists.”
Heart rate fell by an average 1.8 bpm in the controls, and rose by an average 0.3, 0.5, and 3.6 bpm among the three groups receiving ascending weekly tirzepatide doses, effects that were “consistent with what’s been seen with the GLP-1 receptor agonists,” noted Dr. de Lemos.
Tirzepatide is known as a “twincretin” because it shares this GLP-1 receptor agonism and also has a second incretin agonist activity, to the receptor for the glucose-dependent insulinotropic polypeptide.
Lowering of blood pressure plateaus
Changes in BP over time during the 72 weeks on treatment, data first presented in the original report, showed that average systolic pressure in the people who received tirzepatide fell sharply during the first 24 weeks on treatment, and then leveled out with little further change over time. Furthermore, all three tirzepatide doses produced roughly similar systolic BP reductions. Changes in diastolic pressure over time showed a mostly similar pattern of reduction, although a modest ongoing decrease in average diastolic pressure continued beyond 24 weeks.
This pattern of a plateau in BP reduction has been seen before in studies using other treatments to produce weight loss, including bariatric surgery, said Naveed Sattar, MBChB, PhD, professor of metabolic medicine at the University of Glasgow, who was not involved in SURMOUNT-1. He attributed the plateau in BP reduction among tirzepatide-treated people to them hitting a wall in their BP nadir based on homeostatic limits. Dr. Sattar noted that most enrolled participants had normal BPs at entry based on the reported study averages.
“It’s hard to go lower, but the blood pressure reduction may be larger in people who start at higher pressure levels,” Dr. Sattar said in an interview.
Another inferred cap on BP reductions in the trial hypothesizes that the individual clinicians who managed the enrolled patients may have cut back on other BP-lowering agents as the pressures of the tirzepatide recipients fell to relatively low levels, suggested Darren McGuire, MD, a cardiologist and professor at UT Southwestern Medical Center, who also was not involved in the SURMOUNT-1 study.
Incretin agonists as antihypertensive drugs
The substantial BP-lowering seen with tirzepatide, as well as with other incretin agonist agents, suggests a new way to think about BP control in people with overweight or obesity, Dr. Sattar said.
“Until now, we haven’t had tools where people lose so much weight. Now that we have these tools [incretin agonists as well as bariatric surgery], we see substantial blood pressure reductions. It makes you think we should use weight-loss agents to lower blood pressure rather than a beta-blocker or angiotensin-converting enzyme inhibitor; then we’d also produce all the other benefits from weight loss,” Dr. Sattar suggested.
Dr. de Lemos said he sees signals that the BP reductions caused by tirzepatide and the GLP-1 receptor agonists may go beyond just weight-loss effects.
“There appears to be a larger blood pressure reduction than anticipated based on the change in weight,” he said during his presentation. “GLP-1 is active in most vascular tissues, so these [receptor agonist] agents likely have vascular or cardiac effects, or even effects on other tissues that may affect blood pressure.”
Heart rate increases were usually modest
The experiences with GLP-1 receptor agonists also suggest that the heart rate increases seen with tirzepatide treatment in SURMOUNT-1 will not have long-term effects. “The [Food and Drug Administration] mandated this heart rate substudy to make sure that the increase in heart rate was not larger than what would be anticipated” with a GLP-1 receptor agonist, Dr. de Lemos explained.
SURMOUNT-1 had a treatment-stopping rule to prevent a person’s heart rate from rising beyond 10 bpm from baseline. “Trivial numbers” of patients experienced a heart rate increase of this magnitude, he said. If used in routine practice, Dr. de Lemos said that he would closely investigate a patient with a heart rate increase greater than 10 mm Hg. The average increase seen with the highest dose, about 4 bpm above baseline, would generally not be concerning.
Tirzepatide received U.S. marketing approval from the FDA in May 2022 for treating people with type 2 diabetes. In October 2022, the FDA gave tirzepatide “Fast Track” designation for the pending application for approval of an indication to treat people with overweight or obesity who match the entry criteria for SURMOUNT-1 and for the second pivotal trial for this indication, SURMOUNT-2. According to a statement from Eli Lilly, the company that is developing and markets tirzepatide (Mounjaro), the FDA’s decision on the obesity indication will remain pending until the SURMOUNT-2 results are available, which the company expects will occur in 2023.

CHICAGO – compared with placebo, while causing modest increases in heart rate, in a prespecified substudy of the SURMOUNT-1 trial.
“The large effects on ambulatory 24-hour blood pressure raise the possibility that there may be important long-term benefits of [tirzepatide] on the complications of obesity,” said James A. de Lemos, MD, during a presentation at the American Heart Association scientific sessions.
“The findings are concordant with the [previously reported] office-based measurements, and the blood pressure reductions provide further evidence for the potential benefits of tirzepatide on cardiovascular health and outcomes,” said Dr. de Lemos, a cardiologist and professor at the University of Texas Southwestern Medical Center, Dallas.
The substudy included 600 of the 2,539 people enrolled in SURMOUNT-1, the first of two pivotal trials for tirzepatide (Mounjaro) in people without diabetes but with obesity or overweight (body mass index of 27-29 kg/m2) plus at least one weight-related complication. The primary endpoints of SURMOUNT-1 were the percent change in weight from baseline to 72 weeks on treatment with either of three different weekly injected doses of tirzepatide, compared with control subjects who received placebo, and the percentage of enrolled subjects achieving at least 5% loss in baseline weight, compared with the controls.
Tirzepatide treatment led to significant increases in both results, compared with controls, with the highest dose tested, 15 mg/week, resulting in an average 20.9% drop in weight from baseline after 72 weeks of treatment, and 91% of enrolled subjects on that dose achieving the 5% weight-loss threshold during the same time frame, in results published in 2022 in the New England Journal of Medicine.
24-hour ambulatory pressures from 494 people
The substudy enrolled 600 of the SURMOUNT-1 participants and involved 24-hour ambulatory BP and heart rate measurements at entry and after 36 weeks on treatment. Full results were available for 494 of these people. The substudy included only study participants who entered with a BP of less than 140/90 mm Hg. Enrollment in SURMOUNT-1 overall excluded people with a BP of 160/100 mm Hg or higher. The average BP among all enrolled participants was about 123/80 mm Hg, while heart rates averaged about 73 beats per minute.
Systolic BP measured with the ambulatory monitor fell from baseline by an average of 5.6, 8.8, and 6.2 mm Hg in the people who received tirzepatide in weekly doses of 5, 10, or 15 mg, respectively, and rose by an average 1.8 mm Hg among the controls, Dr. de Lemos reported. Diastolic BP dropped among the tirzepatide recipients by an average of 1.5, 2.4, and 0.0 mm Hg in the three ascending tirzepatide treatment arms, and rose by an average 0.5 mm Hg among the controls. All of the differences between the intervention groups and the controls were significant except for the change in diastolic BP among participants who received 15 mg of tirzepatide weekly.
The results showed that 36 weeks on tirzepatide treatment was associated with “arguably clinically meaningful” reductions in systolic and diastolic BPs, Dr. de Lemos said. “There is a lot of optimism that this will translate into clinical benefits.” He also noted that, “within the limits of cross-study comparisons, the blood pressure changes look favorable, compared with the single-incretin mechanism GLP-1 [glucagonlike peptide–1] receptor agonists.”
Heart rate fell by an average 1.8 bpm in the controls, and rose by an average 0.3, 0.5, and 3.6 bpm among the three groups receiving ascending weekly tirzepatide doses, effects that were “consistent with what’s been seen with the GLP-1 receptor agonists,” noted Dr. de Lemos.
Tirzepatide is known as a “twincretin” because it shares this GLP-1 receptor agonism and also has a second incretin agonist activity, to the receptor for the glucose-dependent insulinotropic polypeptide.
Lowering of blood pressure plateaus
Changes in BP over time during the 72 weeks on treatment, data first presented in the original report, showed that average systolic pressure in the people who received tirzepatide fell sharply during the first 24 weeks on treatment, and then leveled out with little further change over time. Furthermore, all three tirzepatide doses produced roughly similar systolic BP reductions. Changes in diastolic pressure over time showed a mostly similar pattern of reduction, although a modest ongoing decrease in average diastolic pressure continued beyond 24 weeks.
This pattern of a plateau in BP reduction has been seen before in studies using other treatments to produce weight loss, including bariatric surgery, said Naveed Sattar, MBChB, PhD, professor of metabolic medicine at the University of Glasgow, who was not involved in SURMOUNT-1. He attributed the plateau in BP reduction among tirzepatide-treated people to them hitting a wall in their BP nadir based on homeostatic limits. Dr. Sattar noted that most enrolled participants had normal BPs at entry based on the reported study averages.
“It’s hard to go lower, but the blood pressure reduction may be larger in people who start at higher pressure levels,” Dr. Sattar said in an interview.
Another inferred cap on BP reductions in the trial hypothesizes that the individual clinicians who managed the enrolled patients may have cut back on other BP-lowering agents as the pressures of the tirzepatide recipients fell to relatively low levels, suggested Darren McGuire, MD, a cardiologist and professor at UT Southwestern Medical Center, who also was not involved in the SURMOUNT-1 study.
Incretin agonists as antihypertensive drugs
The substantial BP-lowering seen with tirzepatide, as well as with other incretin agonist agents, suggests a new way to think about BP control in people with overweight or obesity, Dr. Sattar said.
“Until now, we haven’t had tools where people lose so much weight. Now that we have these tools [incretin agonists as well as bariatric surgery], we see substantial blood pressure reductions. It makes you think we should use weight-loss agents to lower blood pressure rather than a beta-blocker or angiotensin-converting enzyme inhibitor; then we’d also produce all the other benefits from weight loss,” Dr. Sattar suggested.
Dr. de Lemos said he sees signals that the BP reductions caused by tirzepatide and the GLP-1 receptor agonists may go beyond just weight-loss effects.
“There appears to be a larger blood pressure reduction than anticipated based on the change in weight,” he said during his presentation. “GLP-1 is active in most vascular tissues, so these [receptor agonist] agents likely have vascular or cardiac effects, or even effects on other tissues that may affect blood pressure.”
Heart rate increases were usually modest
The experiences with GLP-1 receptor agonists also suggest that the heart rate increases seen with tirzepatide treatment in SURMOUNT-1 will not have long-term effects. “The [Food and Drug Administration] mandated this heart rate substudy to make sure that the increase in heart rate was not larger than what would be anticipated” with a GLP-1 receptor agonist, Dr. de Lemos explained.

Lower hydroxychloroquine dose for lupus tied to hospitalizations for flares
PHILADELPHIA – Patients with systemic lupus erythematosus treated with lower doses of hydroxychloroquine (HCQ) had an increased risk for hospitalization for flares, according to study results presented during a press conference at the annual meeting of the American College of Rheumatology.
HCQ is a cornerstone treatment for SLE as it has been shown to increase survival and decrease disease flares.
Doses decreased with changing guidelines
Guidelines over the years have recommended decreasing doses of HCQ. In 2011, ophthalmology guidelines recommended limiting HCQ dosing to 6.5 mg/kg per day or less of ideal body weight to reduce the chance of retinopathy. For many patients, this required a dose lower than 400 mg/day, an amount frequently used to treat lupus.
In 2016, updated guidelines further lowered the dosage of HCQ, recommending 5 mg/kg or less of patient’s actual body weight.
The effects that lower dosing has had on SLE-associated hospitalizations was unknown, which inspired Dr. Nestor’s research.
The team conducted a case-crossover study within the Mass General Brigham SLE cohort.
Hospitalizations studied over a decade
Dr. Nestor and colleagues identified patients with SLE (via electronic health records) who had at least one visit for SLE and were prescribed HCQ between January 2011 and December 2021, the period over which the recommendations were made.
They identified patients who had been hospitalized during that decade with SLE as the primary discharge diagnosis.
Patients were excluded if they had non-SLE indications, such as kidney transplant or infection without a concomitant SLE flare.
Of 2,971 patients with SLE who used HCQ, 576 had at least one hospitalization with primary discharge diagnosis of SLE.
Of these, 108 were hospitalized for an SLE flare and had used HCQ prior to that hospitalization and had at least one control period with HCQ use during the study period.
All of the patients in the study had to have a case period and a control period, Dr. Nestor explained. The case period was 6 months on HCQ ending in hospitalization for lupus and the control period was 6 months on HCQ that did not end in hospitalization for lupus.
Significantly increased hospitalizations
Low-dose HCQ by weight-based dose (≤ 5 vs. > 5 mg/kg per day) and by non–weight-based dose (< 400 vs. 400 mg per day) were both associated with significantly increased hospitalizations for SLE (adjusted odds ratio, 4.41; 95% confidence interval, 1.50-12.98; and AOR, 3.48; 95% CI, 1.33-9.13, respectively).
The average age of the hospitalized group was 36 years. Most patients (92%) were female, 43.5% were White, and 32.4% were Black.
In calling for reassessment of the dosing, Dr. Nestor said, “We are protecting our patients against a very long-term side effect of hydroxychloroquine retinopathy. [It] typically takes 10-20 years to develop in our patients. But by doing that, we’re missing many of the short-term benefits from hydroxychloroquine in our patients, leading to more lupus flares, which leads to more end-organ damage.”
She said patients taking HCQ for lupus are asked to see an ophthalmologist once a year to monitor for the side effect, adding that rheumatologists and ophthalmologists could work together to adjust the guidelines.
Dr. Nestor suggested it’s possible that patients need higher doses of HCQ earlier in their disease and lower doses later. “Perhaps it’s just the patients who are particularly active who need the higher doses,” she said.
“I don’t think this question is settled,” he told this news organization. “The 5 mg/kg dose recommendation was based on terms of safety but not of effectiveness. We don’t know what the effective dose of HCQ is, and this study shows that low dose is less effective.”
He agreed there needs to be a risk/benefit balance, but noted, “HCQ retinopathy is very rare and we have great tools to screen for it.”
Study limitations include incomplete information on whether patients adhered to treatment plans and reasons for using lower-dose HCQ.
The study authors and Dr. Duarte Garcia report no relevant financial relationships.

AT ACR 2022
Statins boost glycemia slightly, but CVD benefits prevail
CHICAGO – A new, expanded meta-analysis confirmed the long-known effect that statin treatment has on raising blood glucose levels and causing incident diabetes, but it also documented that these effects are small and any risk they pose to statin users is dwarfed by the cholesterol-lowering effect of statins and their ability to reduce risk for atherosclerotic cardiovascular disease (ASCVD).
This meta-analysis of 23 trials with a total of more than 150,000 participants showed that statin therapy significantly increased the risk for new-onset diabetes and worsening glycemia, driven by a “very small but generalized increase in glucose,” with a greater effect from high-intensity statin regimens and a similar but somewhat more muted effect from low- and moderate-intensity statin treatment, David Preiss, MBChB, PhD, reported at the American Heart Association scientific sessions.
Dr. Preiss also stressed that despite this, “the cardiovascular benefits of statin therapy remain substantial and profound” in people regardless of whether they have diabetes, prediabetes, or normoglycemia when they start statin treatment, noting that the impact of even high-intensity statin treatment is “absolutely tiny” increases in hemoglobin A1c and blood glucose.
“This does not detract from the substantial benefit of statin treatment,” declared Dr. Preiss, a metabolic medicine specialist and endocrinologist at Oxford (England) University.
Small glycemia increases ‘nudge’ some into diabetes
The data Dr. Preiss reported showed that high-intensity statin treatment (atorvastatin at a daily dose of at least 40 mg, or rosuvastatin at a daily dose of at least 20 mg) led to an average increase in A1c levels of 0.08 percentage points among people without diabetes when their treatment began and 0.24 percentage points among people already diagnosed with diabetes. Blood glucose levels rose by an average of 0.04 mmol/L (less than 1 mg/d) in those without diabetes, and by an average 0.22 mmol/L (about 4 mg/dL) in those with diabetes. People who received low- or moderate-intensity statin regimens had significant but smaller increases.
“We’re not talking about people going from no diabetes to frank diabetes. We’re talking about [statins] nudging a very small number of people across a diabetes threshold,” an A1c of 6.5% that is set somewhat arbitrarily based on an increased risk for developing retinopathy, Dr. Preiss said. ”A person just needs to lose a [daily] can of Coke’s worth of weight to eliminate any apparent diabetes risk,” he noted.
Benefit outweighs risks by three- to sevenfold
Dr. Preiss presented two other examples of what his findings showed to illustrate the relatively small risk posed by statin therapy compared with its potential benefits. Treating 10,000 people for 5 years with a high-intensity statin regimen in those with established ASCVD (secondary prevention) would result in an increment of 150 extra people developing diabetes because of the hyperglycemic effect of statins, compared with an expected prevention of 1,000 ASCVD events. Among 10,000 people at high ASCVD risk and taking a high-intensity statin regimen for primary prevention 5 years of treatment would result in roughly 130 extra cases of incident diabetes while preventing about 500 ASCVD events.
In addition, applying the new risk estimates to the people included in the UK Biobank database, whose median A1c is 5.5%, showed that a high-intensity statin regimen could be expected to raise the prevalence of those with an A1c of 6.5% or greater from 4.5% to 5.7%.
Several preventive cardiologists who heard the report and were not involved with the analysis agreed with Dr. Preiss that the benefits of statin treatment substantially offset this confirmed hyperglycemic effect.
Risk ‘more than counterbalanced by benefit’
“He clearly showed that the small hyperglycemia risk posed by statin use is more than counterbalanced by its benefit for reducing ASCVD events,” commented Neil J. Stone, MD, a cardiologist and professor of medicine at Northwestern University, Chicago. “I agree that, for those with prediabetes who are on the road to diabetes with or without a statin, the small increase in glucose with a statin should not dissuade statin usage because the benefit is so large. Rather, it should focus efforts to improve diet, increase physical activity, and keep weight controlled.”
Dr. Stone also noted in an interview that in the JUPITER trial, which examined the effects of a daily 20-mg dose of rosuvastatin (Crestor), a high-intensity regimen, study participants with diabetes risk factors who were assigned to rosuvastatin had an onset of diabetes that was earlier than people assigned to placebo by only about 5.4 weeks, yet this group had evidence of significant benefit.
“I agree with Dr. Preiss that the benefits of statins in reducing heart attack, stroke, and cardiovascular death far outweigh their modest effects on glycemia,” commented Brendan M. Everett, MD, a cardiologist and preventive medicine specialist at Brigham and Women’s Hospital in Boston. “This is particularly true for those with preexisting prediabetes or diabetes, who have an elevated risk of atherosclerotic events and thus stand to derive more significant benefit from statins. The benefits of lowering LDL cholesterol with a statin for preventing seriously morbid, and potentially fatal, cardiovascular events far outweigh the extremely modest, or even negligible, increases in the risk of diabetes that could be seen with the extremely small increases in A1c,” Dr. Everett said in an interview.
The new findings “reaffirm that there is a increased risk [from statins] but the most important point is that it is a very, very tiny difference in A1c,” commented Marc S. Sabatine, MD, a cardiologist and professor at Harvard Medical School, Boston. “These data have been known for quite some time, but this analysis was done in a more rigorous way.” The finding of “a small increase in risk for diabetes is really because diabetes has a biochemical threshold and statin treatment nudges some people a little past a line that is semi-arbitrary. It’s important to be cognizant of this, but it in no way dissuades me from treating patients aggressively with statins to reduce their ASCVD risk. I would monitor their A1c levels, and if they go higher and can’t be controlled with lifestyle we have plenty of medications that can control it,” he said in an interview.
No difference by statin type
The meta-analysis used data from 13 placebo-controlled statin trials that together involved 123,940 participants and had an average 4.3 years of follow-up, and four trials that compared one statin with another and collectively involved 30,734 participants with an average 4.9 years of follow-up.
The analyses showed that high-intensity statin treatment increased the rate of incident diabetes by a significant 36% relative to controls and increased the rate of worsening glycemia by a significant 24% compared with controls. Low- or moderate-intensity statin regimens increased incident diabetes by a significant 10% and raised the incidence of worsening glycemia by a significant 10% compared with controls, Dr. Preiss reported.
These effects did not significantly differ by type of statin (the study included people treated with atorvastatin, fluvastatin, lovastatin, pravastatin, rosuvastatin, and simvastatin), nor across a variety of subgroups based on age, sex, race, body mass index, diabetes risk, renal function, cholesterol levels, or cardiovascular disease. The effect was also consistent regardless of the duration of treatment.
Dr. Preiss also downplayed the magnitude of the apparent difference in risk posed by high-intensity and less intense statin regimens. “I suspect the apparent heterogeneity is true, but not quite as big as what we see,” he said.
The mechanisms by which statins have this effect remain unclear, but evidence suggests that it may be a direct effect of the main action of statins, inhibition of the HMG-CoA reductase enzyme.
The study received no commercial funding. Dr. Preiss and Dr. Stone had no disclosures. Dr. Everett has been a consultant to Eli Lilly, Gilead, Ipsen, Janssen, and Provention. Dr. Sabatine has been a consultant to Althera, Amgen, Anthos Therapeutics, AstraZeneca, Beren Therapeutics, Bristol-Myers Squibb, DalCor, Dr Reddy’s Laboratories, Fibrogen, Intarcia, Merck, Moderna, Novo Nordisk, and Silence Therapeutics.
CHICAGO – A new, expanded meta-analysis confirmed the long-known effect that statin treatment has on raising blood glucose levels and causing incident diabetes, but it also documented that these effects are small and any risk they pose to statin users is dwarfed by the cholesterol-lowering effect of statins and their ability to reduce risk for atherosclerotic cardiovascular disease (ASCVD).
This meta-analysis of 23 trials with a total of more than 150,000 participants showed that statin therapy significantly increased the risk for new-onset diabetes and worsening glycemia, driven by a “very small but generalized increase in glucose,” with a greater effect from high-intensity statin regimens and a similar but somewhat more muted effect from low- and moderate-intensity statin treatment, David Preiss, MBChB, PhD, reported at the American Heart Association scientific sessions.
Dr. Preiss also stressed that despite this, “the cardiovascular benefits of statin therapy remain substantial and profound” in people regardless of whether they have diabetes, prediabetes, or normoglycemia when they start statin treatment, noting that the impact of even high-intensity statin treatment is “absolutely tiny” increases in hemoglobin A1c and blood glucose.
“This does not detract from the substantial benefit of statin treatment,” declared Dr. Preiss, a metabolic medicine specialist and endocrinologist at Oxford (England) University.
Small glycemia increases ‘nudge’ some into diabetes
The data Dr. Preiss reported showed that high-intensity statin treatment (atorvastatin at a daily dose of at least 40 mg, or rosuvastatin at a daily dose of at least 20 mg) led to an average increase in A1c levels of 0.08 percentage points among people without diabetes when their treatment began and 0.24 percentage points among people already diagnosed with diabetes.

AT AHA 2022
Steroids and G-CSF improve 90-day survival in severe alcoholic hepatitis
, researchers from India reported.
Among patients with SAH, the combination of G-CSF and prednisolone was associated with a 90-day survival rate of 88.1%, compared with 78.6% for patients assigned to G-CSF alone, and 64.3% for patients assigned to prednisolone alone (P = .03).
The G-CSF/prednisolone combination was also associated with significantly better steroid responsiveness, as determined by the Lille Model for Alcoholic Hepatitis, reported Shiv K. Sarin, MD, from the Institute of Liver and Biliary Sciences, New Delhi.
The drug combo in steroid-eligible patients also “reduces morbidity related to infections, rehospitalizations, and hepatic encephalopathy [and] reduces infection rates,” Dr. Sarin said at the annual meeting of the American Association for the Study of Liver Diseases. He did caution that the treatment requires close monitoring.
Prednisolone-only drawbacks
For patients with SAH, 30-day mortality ranges from 20%-50%. While some patients respond to treatment with corticosteroids, the response is often modest and limited in duration, Dr. Sarin said.
The STOPAH trial found that 15% of patients with SAH treated with prednisolone developed serious infections, compared with 8% of patients on placebo (P = .002), he noted.
Dr. Sarin also pointed to a recent worldwide study attempting to identify the optimal therapeutic window for steroid use in patients with alcoholic hepatitis. The investigators found that corticosteroids reduced 30-day mortality by 41% but only among patients with SAH, especially those with Model for End-Stage Liver Disease (MELD) scores between 25 and 39.
In previous studies, G-CSF has been shown to improve survival in patients with acute-on-chronic liver failure, including patients with SAH; in patients with SAH alone; and in steroid nonresponders, Dr. Sarin said.
Regenerative properties
In an interview with this news organization, Dr. Sarin said that although the use of G-CSF for patients with severe SAH is still under investigation at his center, “we are using G-CSF routinely for decompensated cirrhosis, where it is like an in vivo extension of regenerative stem cells. G-CSF recruits from bone marrow a lot of hematopoietic stem cells and mesenchymal stem cells.”
Dr. Sarin and colleagues hypothesized that G-CSF, with its immunomodulatory and regenerative properties, would be effective either alone or in combination with steroids in steroid-eligible patients with SAH.
To test this idea, they enrolled 126 patients ages 18-65 with SAH, defined as a Maddrey’s Discriminant Function (mDF) score greater than 32. They excluded patients with active infections, acute gastrointestinal bleeding, hepatorenal syndrome, an mDF score greater than 90, autoimmune hepatitis, hepatitis B or C, HIV, pregnancy, hemophagocytic lymphohistiocytosis, and those with hemoglobin below 8 and baseline white blood cell count over 25,000.
The patients were randomly assigned, 42 in each group, to receive one of the following:
- Prednisolone monotherapy 40 mg/day for 7 days, with the drug stopped at 7 days for patients with Lille scores above 0.45 or continued for up to 21 days for those with Lille scores below 0.45;
- Prednisolone plus G-CSF 300 mcg/day for 7 days, with those who achieve a Lille score above 0.45 stopping the steroid but continuing G-CSF, while those with Lille scores below 0.45 continuing on prednisolone for 21 days, plus G-CSF once every 3 days for 5 additional doses; or
- G-CSF monotherapy at a dose of 150-300 mcg/day for 7 days, then every 3 days for 28 days up to a total of 12 doses.
Improved response
In addition to its superior results on the primary endpoint of 90-day survival, combination therapy was associated with significantly better response to therapy. The mean Lille score at day 7 was 0.14 for the combination, compared with 0.21 for prednisolone alone and 0.28 for G-CSF alone (P = .002).
There were also significantly fewer nonresponders in the combination arm than either of the monotherapy groups (P = .03).
At 90 days, the rate of new infections was significantly higher among patients treated with prednisolone alone, at 35.7%, compared with 19% in the combination arm and 7.1% in the G-CSF alone group (P = .02). There were also significantly fewer skin and mucosal bleeding episodes with the combination (19% vs, 25% and 35.7% with prednisolone and G-CSF monotherapies, respectively, P = .03), as well as lower rates of hepatic encephalopathy (9.5% vs. 47.5% and 25%, respectively, P < .01).
No differences in alcohol relapse rates were found among the three groups.
Patient selection important
“I know a lot of the G-CSF studies that have been conducted in the U.S. and Europe have all been negative,” said David Goldberg, MD, from the University of Miami, during the session. “Do you think there’s something unique in your patients, the microbiome or maybe genetics, that leads to such different results?” he asked Dr. Sarin.
European studies included patients with infections, acute kidney injury (AKI), or other comorbidities that were exclusion criteria in his study, Dr. Sarin noted.
“If you already have an infection, you already have an AKI, then it’s not a good patient for treatment, so I think the choice of patient is important,” he said.
The study was internally supported. Dr. Sarin and Dr. Goldberg report no relevant financial relationships.

Among patients with SAH, the combination of G-CSF and prednisolone was associated with a 90-day survival rate of 88.1%, compared with 78.6% for patients assigned to G-CSF alone, and 64.3% for patients assigned to prednisolone alone (P = .03).
The G-CSF/prednisolone combination was also associated with significantly better steroid responsiveness, as determined by the Lille Model for Alcoholic Hepatitis, reported Shiv K. Sarin, MD, from the Institute of Liver and Biliary Sciences, New Delhi.
The drug combo in steroid-eligible patients also “reduces morbidity related to infections, rehospitalizations, and hepatic encephalopathy [and] reduces infection rates,” Dr. Sarin said at the annual meeting of the American Association for the Study of Liver Diseases. He did caution that the treatment requires close monitoring.
Prednisolone-only drawbacks
For patients with SAH, 30-day mortality ranges from 20%-50%. While some patients respond to treatment with corticosteroids, the response is often modest and limited in duration, Dr. Sarin said.
The STOPAH trial found that 15% of patients with SAH treated with prednisolone developed serious infections, compared with 8% of patients on placebo (P = .002), he noted.
Dr. Sarin also pointed to a recent worldwide study attempting to identify the optimal therapeutic window for steroid use in patients with alcoholic hepatitis. The investigators found that corticosteroids reduced 30-day mortality by 41% but only among patients with SAH, especially those with Model for End-Stage Liver Disease (MELD) scores between 25 and 39.
In previous studies, G-CSF has been shown to improve survival in patients with acute-on-chronic liver failure, including patients with SAH; in patients with SAH alone; and in steroid nonresponders, Dr. Sarin said.
Regenerative properties
In an interview with this news organization, Dr. Sarin said that although the use of G-CSF for patients with severe SAH is still under investigation at his center, “we are using G-CSF routinely for decompensated cirrhosis, where it is like an in vivo extension of regenerative stem cells. G-CSF recruits from bone marrow a lot of hematopoietic stem cells and mesenchymal stem cells.”
Dr. Sarin and colleagues hypothesized that G-CSF, with its immunomodulatory and regenerative properties, would be effective either alone or in combination with steroids in steroid-eligible patients with SAH.
To test this idea, they enrolled 126 patients ages 18-65 with SAH, defined as a Maddrey’s Discriminant Function (mDF) score greater than 32. They excluded patients with active infections, acute gastrointestinal bleeding, hepatorenal syndrome, an mDF score greater than 90, autoimmune hepatitis, hepatitis B or C, HIV, pregnancy, hemophagocytic lymphohistiocytosis, and those with hemoglobin below 8 and baseline white blood cell count over 25,000.
The patients were randomly assigned, 42 in each group, to receive one of the following:
- Prednisolone monotherapy 40 mg/day for 7 days, with the drug stopped at 7 days for patients with Lille scores above 0.45 or continued for up to 21 days for those with Lille scores below 0.45;
- Prednisolone plus G-CSF 300 mcg/day for 7 days, with those who achieve a Lille score above 0.45 stopping the steroid but continuing G-CSF, while those with Lille scores below 0.45 continuing on prednisolone for 21 days, plus G-CSF once every 3 days for 5 additional doses; or
- G-CSF monotherapy at a dose of 150-300 mcg/day for 7 days, then every 3 days for 28 days up to a total of 12 doses.
Improved response
In addition to its superior results on the primary endpoint of 90-day survival, combination therapy was associated with significantly better response to therapy. The mean Lille score at day 7 was 0.14 for the combination, compared with 0.21 for prednisolone alone and 0.28 for G-CSF alone (P = .002).
There were also significantly fewer nonresponders in the combination arm than either of the monotherapy groups (P = .03).
At 90 days, the rate of new infections was significantly higher among patients treated with prednisolone alone, at 35.7%, compared with 19% in the combination arm and 7.1% in the G-CSF alone group (P = .02). There were also significantly fewer skin and mucosal bleeding episodes with the combination (19% vs, 25% and 35.7% with prednisolone and G-CSF monotherapies, respectively, P = .03), as well as lower rates of hepatic encephalopathy (9.5% vs. 47.5% and 25%, respectively, P < .01).
No differences in alcohol relapse rates were found among the three groups.
Patient selection important
“I know a lot of the G-CSF studies that have been conducted in the U.S. and Europe have all been negative,” said David Goldberg, MD, from the University of Miami, during the session. “Do you think there’s something unique in your patients, the microbiome or maybe genetics, that leads to such different results?” he asked Dr. Sarin.
European studies included patients with infections, acute kidney injury (AKI), or other comorbidities that were exclusion criteria in his study, Dr. Sarin noted.
“If you already have an infection, you already have an AKI, then it’s not a good patient for treatment, so I think the choice of patient is important,” he said.
The study was internally supported. Dr. Sarin and Dr. Goldberg report no relevant financial relationships.

FROM THE LIVER MEETING
Remibrutinib safe for Sjögren’s in phase 2
PHILADELPHIA – Oral remibrutinib was well tolerated and had a good safety profile over 24 weeks among patients with moderate to severe Sjögren syndrome (SS), according to new phase 2 data presented at the annual meeting of the American College of Rheumatology.
Thomas Dörner, MD, with the department of rheumatology and clinical immunology at Charité Universitätsmedizin Berlin, presented the data from the double-blind, randomized, placebo-controlled, proof-of-concept study.
The authors said the results of the study suggest that remibrutinib, a highly specific inhibitor of Bruton tyrosine kinase, has the potential to become the first effective oral disease-modifying therapy for SS.
The 73 participants in the study had moderate to severe SS. The baseline EULAR Sjögren Syndrome Disease Activity Index (ESSDAI) score was at least 5, EULAR Sjögren Syndrome Patient Reported Index (ESSPRI) was at least 5, and anti-Ro/SSA antibody positivity was 3 months or less before screening. The patients’ unstimulated whole salivary flow rate was > 0 mL/min.
Overall, 73 patients (71 women) were randomly assigned to receive either remibrutinib 100 mg twice a day (n = 24), remibrutinib 100 mg four times a day (n = 25), or placebo (n = 24) between August 2019 and May 2021.
Remibrutinib met the primary endpoint and resulted in a statistically significant improvement in ESSDAI score for both regimens combined compared with placebo at week 24 (ESSDAI, –2.86).
Patient-reported outcomes similar to placebo
Patient-reported outcomes, including scores on ESSPRI, Functional Assessment of Chronic Illness Therapy–Fatigue, and EuroQol-5 Dimension, were similar in the treatment groups and the placebo group.
“All of the patients, including the placebo patients, improved over the time of the study,” Dr. Dörner said.
The average age of the patients was 51.8 years (range, 18-75 years). Groups were generally balanced with regard to demographic qualities and disease severity at baseline, and the patients represented the SS population well, Dr. Dörner said.
No severe adverse events were reported. Infections were the most frequently reported adverse events, and the rates were similar with the study drug and placebo. No notable liver abnormalities were reported in any of the groups.
Chrisanna Dobrowolski, MD, assistant professor of medicine at Icahn School of Medicine at Mount Sinai in New York, told this news organization, “Preliminary results are promising, but they failed to show improvements in patient-reported quality-of-life measures.
“Having statistical improvements in disease activity measures without clinically meaningful improvement in patient quality of life may limit the value of this treatment,” she said.
Dr. Dobrowolski added that the follow-up period of 6 months is short, and larger studies over a longer period are needed to better assess the effect on patients’ quality of life.
“Regardless, this is the first oral medication which has shown disease-modifying potential for the glandular symptoms of SS and is an exciting new avenue of investigation to be further explored,” she said.
Patients with SS 15 to 20 times more likely to develop B-cell lymphoma as a life-threatening complication. SS is a systemic autoimmune disease characterized by B-cell hyperactivation, lymphoid infiltration, progressive destruction of exocrine glands, and various complications outside the glands, the study authors wrote in the abstract.
Nearly 4 million in U.S. live with the disease
Nearly 4 million people in the United States live with the disease. Common symptoms include light sensitivity, dry eye, dry mouth, fatigue, and joint pain.
SS can be difficult to diagnose because the symptoms vary from person to person and can be confused with those caused by other diseases.
Ardy Fenando, MD, a rheumatology fellow with the University of Kansas Medical Center, said in an interview, “We need more therapies for Sjögren’s. Heterogeneity complicates the way we set the primary endpoints. Therefore, we haven’t had a proven treatment for Sjögren’s. This is supported by previous RCTs [randomized controlled trials] that failed to meet the primary end points.”
Dr. Dörner has relationships with AbbVie, Eli Lilly, Roche/Genentech, Janssen, Novartis, Bristol-Myers Squibb), and UCB. Other authors have various relationships with industry. Dr. Fenando and Dr. Dobrowolski have disclosed no relevant financial relationships.

Retention rates high after biosimilar-to-biosimilar switch for inflammatory arthritis
PHILADELPHIA – When patients with inflammatory rheumatic diseases were switched from one biosimilar agent to another, treatment retention rates were high, investigators in Denmark reported.
The findings suggest patient-related factors rather than drug-related factors appear to determine whether patients will stay on the new drug, the researchers said.
One year after a Danish government-mandated switch from one infliximab (Remicade) biosimilar to another equally efficacious but less costly biosimilar, 83% of patients who had started therapy on a biosimilar (so-called “originator-naive” patients) stayed on the newly assigned therapy. And so did 92% of patients who had started on the original infliximab (“originator experienced”) before they were switched to one biosimilar and then another.
“In regards to potential baseline predictors, we found that treatment withdrawal was more frequent among originator-naive switchers and patients with higher baseline disease activity, especially [in] patient-reported outcomes, which may indicate that treatment-related outcomes may be more affected by patient-related rather than drug-related factors,” said lead author Hafsah Nabi, MD from the Danish biosimilar registry DANBIO and a PhD candidate at the Copenhagen Center for Arthritis Research.
Dr. Nabi reported the results in an oral abstract session at the annual meeting of the American College of Rheumatology.
Annual review of biologic agents
In Denmark, health authorities issue annual recommendations for the use of biologic agents. “And since patients receive this treatment free from the hospital, based on the tax system, the switches are made due to these cost considerations,” Dr. Nabi said in an interview.
To get the nod from Danish pharmaceutical regulators, pharmaceutical manufacturers submit drugs that have already been approved by the European Medicines Agency for consideration for treatment of specific indications, explained coauthor Merete Lund Hetland, MD, PhD, DMSc, from Rigshospitalet in Copenhagen.
“Those drugs that are then considered equally safe and effective are invited to this process where they will give their bid, and then the cheapest one will win,” she said.
The winning formulation will be able to capture about 80% of prescriptions for that indication for the coming year.
Awake at the switch
Dr. Nabi, Dr. Hetland, and colleagues studied how one such recent government-mandated switch from one biosimilar to another affected efficacy and patterns of care among patients with rheumatoid arthritis, psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA).
To identify prior comorbidities, they drew data from the DANBIO registry, which is linked to patient specific but anonymous data from other comprehensive birth-to-death patient registries in Denmark.
They looked at all patients with RA, PsA, or axSpA who were switched from CT-P13 (Remsira, Inflectra) to GP1111 (Zessly) from April 1, 2019, to Feb. 1, 2020.
They identified a total of 1,605 patients, including 685 with RA, 314 with PsA, and 606 with axSpa. The median disease duration was 9 years, and 37% of all patients were in remission according to Clinical Disease Activity Index or Ankylosing Spondylitis Disease Activity Scale.
Of this group, 1,171 had started therapy on a biosimilar.
As noted above, 83% of patients who had never received original infliximab, and 92% of those who were originator experienced were still on the new biosimilar 1 year after the switch.
In a multivariate analysis controlling for demographic and clinical factors at baseline, the variables significantly associated with treatment withdrawal from the new biosimilar (GP11110) included previous Remicade exposure (hazard ratio, 0.36), methotrexate use (HR, 0.60), and patient-reported global visual analog scale (HR, 1.02).
Among all patients, disease activity was stable 6 months before and after the switch, Dr. Nabi said, although she did not show data to support it.
Patient education benefit
During the session, Jonathan Kay, MD, professor of rheumatology and chair of the division of rheumatology at the University of Massachusetts, Worcester, who was not involved the study, asked Dr. Nabi whether patients were educated about equivalent efficacy and safety of biosimilars prior to the switch. He noted that education prior to switching led to a much lower patient withdrawal rate in a similar switching study conducted in The Netherlands.
“In this study, we haven’t looked more specifically into the education and which strategies have been used prior to switching, and we also conclude in the study that there may be the presence of a nocebo effect, which can be handled by better educating the patients,” she replied.
The nocebo effect refers to the phenomenon in which a patient’s belief that a specific intervention may cause harm actually can lead to negative outcomes – in other words, the opposite of the placebo effect.
In an interview, Dr. Kay said that he is confident about the efficacy, safety, and equivalency of approved biosimilar agents.
“A biosimilar that has been reviewed and approved by a regulatory agency such as the [Food and Drug Administration or the [European Medicines Agency] should be equivalent in efficacy and comparable in safety and immunogenicity. I would be fully confident in switching from the reference product to the biosimilar,” he said.
Dr. Nabi reported that the study was partly funded by a research grant from Sandoz, the maker of GP1111. Dr. Hetland has disclosed grants from various companies, not including Sandoz. Dr. Kay disclosed consulting fees from various companies, not including Sandoz.

Rituximab ‘a reasonable alternative to cyclophosphamide’ to improve ILD-CTD
PHILADELPHIA – In the first controlled clinical trial to compare the two drugs, rituximab and cyclophosphamide were similarly effective in improving lung function in patients with interstitial lung disease (ILD) associated with idiopathic inflammatory myositis and mixed connective tissue disease (CTD). The findings also revealed some nuanced findings that could help clarify which drug to use in specific patients.
“We feel that rituximab is a reasonable alternative to cyclophosphamide as a treatment in patients with these diseases,” said Toby Maher, MD, of the University of Southern California, Los Angeles, who presented results of an analysis of three disease subgroups from the RECITAL (Rituximab versus Cyclophosphamide for the Treatment of Connective Tissue Disease Associated Interstitial Lung Disease) study at the annual meeting of the American College of Rheumatology.
“We didn’t show it to be better, so I think you can reasonably choose between the two, but rituximab almost certainly has the advantage of being safer and better tolerated than cyclophosphamide,” Dr. Maher said in an interview. The findings were published simultaneously in The Lancet Respiratory Medicine.
Double-blind, double-dummy
RECITAL is a phase 2b, randomized, controlled trial to test the hypothesis that intravenous rituximab would be superior to cyclophosphamide for ILD-associated CTD.
The study included adults with three separate diagnoses: myositis (n = 44), mixed CTD (n = 16), and systemic sclerosis (SSc, n = 37). The study was done in the United Kingdom when Dr. Maher was with Imperial College London.
Patients in the rituximab group received 1,000 mg of IV treatment at baseline and 2 weeks, then placebo treatment every 4 weeks to week 20. Cyclophosphamide patients received 600 mg/m2 of body surface area intravenously every 4 weeks for six doses.
“When we designed this study there was limited evidence for any treatment for any disease associated with ILD,” Dr. Maher said. “But cyclophosphamide brings with it many challenges. It can be poorly tolerated and carries issues like infertility and risk of bladder cancer.”
Improved lung function
While the study failed to meet its primary endpoint – superiority of rituximab versus cyclophosphamide – it did show that both drugs led to improvement in lung function, measured by the rate of change in forced vital capacity (FVC), as well as quality of life measures, Dr. Maher said.
“Overall by week 48, we saw about a 5% improvement in FVC in the cyclophosphamide group and approximately a 4% improvement in FVC from baseline in the rituximab group, suggesting that both drugs almost certainly had a positive benefit in this patient group,” he said.
But secondary outcomes varied somewhat across the different disease groups. Patients with SSc saw a slight deterioration with cyclophosphamide in the modified Rodnan skin score at 24 weeks (1.6 ± 5.7 units) but an improvement with rituximab (–3.4 ± 8.1 units).
“One area where we did see a difference was in the number of adverse events,” Dr. Maher said. “They were fewer in the rituximab arm – namely gastrointestinal disorders [and] nausea, which we saw quite frequently following cyclophosphamide. Also, they had fewer headaches, which we saw quite frequently following cyclophosphamide.”
Rituximab patients also had fewer infusion reactions, but the number of infections was similar between the two treatment groups, he said.
“The patient group that responded best to treatment was the myositis group,” Dr. Maher said in his presentation. “Cyclophosphamide actually appears to be more effective than rituximab in improving their disease. By the end of 48 weeks, the cyclophosphamide group actually gained about 400 mL in FVC, so a close to 20% improvement.”
The rituximab group had “a little bit of a drop-off” in efficacy from weeks 24 to 48, although the trial didn’t repeat dosing at 6 months, “which is what perhaps one might do in clinical practice,” he said.
Oliver Distler, MD, chair of rheumatology at the University Hospital Zürich, raised questions about concurrent corticosteroid use in study patients that may have caused a “spillover” in the study’s efficacy analysis. But Dr. Maher noted that steroid use was balanced in all treatment arms. Patients in the cyclophosphamide arm averaged 42.9 mg of hydrocortisone daily versus 37.6 mg daily in the rituximab arm. That represents a 12.3% reduction in steroid exposure for the latter.
Dr. Distler noted that the myositis population represented the bulk of those study patients on steroids. “So in the myositis subanalysis we do see a combination of high-dose steroid plus cyclophosphamide and rituximab.”
Dr. Maher disclosed relationships with Boehringer Ingelheim, Genentech, GlaxoSmithKline, Bristol-Myers Squibb, AstraZeneca, Trevi, CSL Behring, Pliant and Veracyte. Dr. Distler disclosed relationships with numerous pharmaceutical companies.

How AI is, or will soon be, relevant in radiation oncology
Artificial intelligence (AI) is impacting many aspects of health care, and radiation oncology is no exception. It has the potential to cut costs and streamline work flows ranging from image analysis to treatment plan formulation, but its specific place in clinical practice is still being debated.
In a session at the annual meeting of the American Society for Radiation Oncology, researchers discussed some of the ways that AI is or will soon be relevant to the clinic. The general consensus was that
In his talk, Sanjay Aneja, MD focused on practical applications of AI that are in the clinic or close to being ready. One example is image classification. “There has been recent evidence that suggests in a variety of different kind of scenarios, deep-learning models can be very good at image classification in automated ways,” said Dr. Aneja, who is a professor of radiology at Yale University, New Haven, Conn. He described one study that used AI to classify 14 different pathologies on chest x-ray images.
Dr. Aneja described the open-source nnU-net tool, which automatically configures itself and segments biomedical images for research or clinical purposes, including therapy planning support, intraoperative support, and tumor growth monitoring. The researchers who developed it also created a “recipe” to systematize configuration of nnU-net, making it useful as an out-of-the-box tool for image segmentation.
He predicted that AI will improve radiology oncology by assisting in the determination of disease extent, including microscopic areas of disease. It could also help plan treatment volume and monitor treatment response. “I think that these are the types of things that will be moving toward the clinic in the future; very specific applications and models trained on very specific scenarios that will help us answer a very important clinical question,” Dr. Aneja said.
He expects AI to contribute to auto-segmenting and clinical contouring, “but I will caution everyone that these algorithms have not been proven to be better than physician contours. They very frequently fail in the specific use cases when anatomy is distorted by, I don’t know, say a tumor. And so a lot of times, we don’t actually have the ability to just make it an automated process. I think it’ll be something that physicians will use to help them but not necessarily replace their contouring ability,” Dr. Aneja said.
Another, potentially more useful application, is in adaptive radiation planning. “I think that AI auto-contouring will be very helpful in establishing contours in a situation in which a physician doing them would not be feasible. We need to have nimble and computationally efficient auto segmentation algorithms that will be able to be easily deployed at the linear accelerator,” he said.
AI in pathology and treatment selection
In another talk, Osama Mohamad, MD talked about AI in pathology, and specifically treatment selection. He described research from his group that digitized pathology data from 5,500 patients drawn from five randomized, clinical trials. They used AI on data from four of the clinical trials to identify a prognostic biomarker for distant metastasis, then validated it on data from the remaining clinical trial, which compared radiation versus radiation plus short-term hormone therapy in prostate cancer.
The results suggested that most patients should receive hormone therapy, but the AI suggested a more nuanced answer. “Patients who had AI biomarker negative do not see any benefit from adding 4 months of hormone therapy ... whereas patients who have biomarker positive have significant difference and improvement in distant metastasis at 10 years and 15 years. This means that we can save a significant proportion of patients from getting [androgen deprivation therapy], which is hormonal therapy and has very well-known side effects, because they simply they will not benefit,” said Dr. Mohamad, who is an assistant professor of radiation oncology at University of California, San Francisco.
That study relied on the ArteraAI prostate cancer test, which is available through a Clinical Laboratory Improvement Amendment–certified laboratory in Florida.
Another example of AI used to plan treatment is On-line Real-time Benchmarking Informatics Technology for Radiotherapy (ORBIT-RT), developed at the University of California, San Diego. It focuses on radiotherapy treatment plan quality control, and has two main components: creating clinically validated plan routines and a free radiotherapy plan quality control system.
No matter how impressive the technical advances may be, AI contributions won’t impact clinical practice if radiation oncologists, physicians, and patients don’t accept AI. Dr. Aneja’s group surveyed patients about which health field they would feel more comfortable with AI having an important role. Most said they were extremely uncomfortable when it came to cancer. “Now, does that mean that we can’t use AI in oncology? No, I think it just means that we have to be a little bit more nuanced in our approach and how we develop AI solutions for cancer patients,” Dr. Aneja said.
Physicians also show reluctance, according to Alejandro Berlin, MD, who is an affiliate scientist at Princess Margaret Cancer Centre in Toronto. He discussed some research looking at physician acceptance of machine learning. His group looked at physician acceptance of treatment plans for prostate cancer that were generated by physicians and in parallel by machine learning. In a theoretical phase, physicians generally agreed that the machine learning plans were better, but when it came to a phase of the study in which physicians chose which plan to implement in a real patient, the acceptance of machine learning-generated plans dropped by 20%.
This tendency to trust humans over machines is what Dr. Berlin called “automation bias,” and he called for a more collaborative approach to implement AI. “In some cases, [machine learning] is going to be good and sufficient. And in some cases, you will need the expertise of a human.”
Dr. Aneja, who also moderated the session, expressed a similar sentiment when summing up the day’s talks: “I do feel like it’s a disruptive technology ... but I think there will still be a need for us to have people who are trained in order to evaluate and make sure that these algorithms are working correctly and efficiently.”
Dr. Aneja, Dr. Mohamad, and Dr. Berlin have no relevant financial disclosures.
