Rheumatology

Among people with COVID-19, those with systemic autoimmune rheumatic diseases had an elevated 30-day risk of hospitalization, ICU admission, need for mechanical ventilation, and acute kidney injury, compared to a group without rheumatic diseases at 4 months in a match-controlled study.

When investigators expanded the study to 6 months, the difference in need for mechanical ventilation disappeared. However, relative risk for venous thromboembolism (VTE) emerged as 74% higher among people with COVID-19 and with rheumatic disease, said Kristin D’Silva, MD, who presented the findings during a plenary session at the virtual annual meeting of the American College of Rheumatology. She noted that rheumatic disease itself could contribute to VTE risk.

Comorbidities including hypertension, diabetes, and asthma were more common among people with systemic autoimmune rheumatic diseases (SARDs). After adjustment for comorbidities, “the risks of hospitalization and ICU admission were attenuated, suggesting comorbidities are likely key mediators of the increased risk of severe COVID-19 outcomes observed in SARDs patients versus comparators,” Dr. D’Silva, a rheumatology fellow at Massachusetts General Hospital in Boston, said in an interview.

“The risk of venous thromboembolism persisted even after adjusting for comorbidities,” Dr. D’Silva said. Patients with SARDs should be closely monitored for VTE during COVID-19 infection, she added. “Patients with significant cardiovascular, pulmonary, and metabolic comorbidities should be closely monitored for severe COVID-19.”

At the same time, a systematic review of 15 published studies revealed a low incidence of COVID-19 infection among people with rheumatic disease. Furthermore, most experienced a mild clinical course and low mortality, Akhil Sood, MD, said when presenting results of his poster at the meeting.

Underlying immunosuppression, chronic inflammation, comorbidities, and disparities based on racial, ethnic, and socioeconomic status could predispose people with rheumatic disease to poorer COVID-19 outcomes. However, the risks and outcomes of COVID-19 infection among this population “are not well understood,” said Dr. Sood, a second-year resident in internal medicine at the University of Texas Medical Branch in Galveston.

Elevated risks in match-controlled study

Dr. D’Silva and colleagues examined a COVID-19 population and compared 716 people with SARDs and another 716 people from the general public at 4 months, as well as 2,379 people each in similar groups at 6 months. They used real-time electronic medical record data from the TriNetX research network to identify ICD-10 codes for inflammatory arthritis, connective tissue diseases, and systemic vasculitis. They also used ICD-10 codes and positive PCR tests to identify people with COVID-19.

Mean age was 57 years and women accounted for 79% of both groups evaluated at 4 months. Those with SARDs were 23% more likely to be hospitalized (relative risk, 1.23; 95% confidence interval, 1.01-1.50). This group was 75% more likely to be admitted to the ICU (RR, 1.75; 95% CI, 1.11-2.75), 77% more likely to require mechanical ventilation (RR, 1.77; 95% CI, 1.06-2.96), and 83% more likely to experience acute kidney injury (RR, 1.83; 95% CI, 1.11-3.00).

Risk of death was not significantly higher in the SARDs group (RR, 1.16; 95% CI, 0.73-1.86).

When Dr. D’Silva expanded the study to more people at 6 months, they added additional 30-day outcomes of interest: renal replacement therapy, VTE, and ischemic stroke. Risk of need for renal replacement therapy, for example, was 81% higher in the SARDs group (RR, 1.81; 95% CI, 1.07-3.07). Risk of stroke was not significantly different between groups.The improvement in mechanical ventilation risk between 4 and 6 months was not completely unexpected, Dr. D’Silva said. The relative risk dropped from 1.77 to 1.05. “This is not particularly surprising given national trends in the general population reporting decreased severe outcomes of COVID-19 including mortality as the pandemic progresses. This is likely multifactorial including changes in COVID-19 management (such as increasing use of nonintubated prone positioning rather than early intubation and treatments such as dexamethasone and remdesivir), decreased strain on hospitals and staffing compared to the early crisis phase of the pandemic, and higher testing capacity leading to detection of milder cases.”

When the 6-month analysis was further adjusted for comorbidities and a history of prior hospitalization within 1 year, only risk for acute kidney injury and VTE remained significant with relative risks of 1.33 and 1.60, respectively, likely because comorbidities are causal intermediates of COVID-19 30-day outcomes rather than confounders.

When asked to comment on the results, session comoderator Victoria K. Shanmugam, MD, said in an interview that the study “is of great interest both to rheumatologists and to patients with rheumatic disease.”

The higher risk of hospitalization, ICU admission, mechanical ventilation, acute kidney injury, and heart failure “is an important finding with implications for how our patients navigate risk during this pandemic,” said Dr. Shanmugam, director of the division of rheumatology at George Washington University in Washington.
 

Lower risks emerge in systematic review

The 15 observational studies in the systematic review included 11,815 participants. A total of 179, or 1.5%, tested positive for COVID-19.

“The incidence of COVID-19 infection among patients with rheumatic disease was low,” Dr. Sood said.

Within the COVID-19-positive group, almost 50% required hospitalization, 10% required ICU admission, and 8% died. The pooled event rate for hospitalization was 0.440 (95% CI, 0.296-0.596), while for ICU admission it was 0.132 (95% CI, 0.087-0.194) and for death it was 0.125 (95% CI, 0.082-0.182).
 

Different calculations of risk

The two studies seem to offer contradictory findings, but the disparities could be explained by study design differences. For example, Dr. D’Silva’s study evaluated a population with COVID-19 and compared those with SARDs versus a matched group from the general public. Dr. Sood and colleagues assessed study populations with rheumatic disease and assessed incidence of SARS-CoV-2 infection and difference in outcomes.

“We are asking very different questions,” Dr. D’Silva said.

“The study by D’Silva et al. was able to account for different factors to reduce confounding,” Dr. Sood said, adding that Dr. D’Silva and colleagues included a high proportion of minorities, compared with a less diverse population in the systematic review, which featured a large number of studies from Italy.

The authors of the two studies had no relevant financial disclosures to report.

Black patients with systemic lupus erythematosus (SLE) are known to have significantly elevated risk for stroke and ischemic heart disease (IHD), compared with non-Black patients with SLE.

Now a team of investigators has identified SLE-specific predictors for major cardiovascular complications in Black patients, pointing to potential prevention strategies in this high-risk population.

Among Black patients in a study of 336 patients with incident SLE, discoid rash at the time of SLE diagnosis predicted a fivefold higher risk for stroke, and renal disorder at the time of diagnosis was associated with a twofold higher risk, compared with non-Black patients, but neither of these symptoms predicted elevated risk of IHD.

In contrast, neurologic disorders, including prior psychosis or seizure, were associated with a fourfold higher risk for IHD, and immunologic disorders including anti-DNA, anti-Smith, or antiphospholipid antibodies were associated with a nearly fivefold greater risk for IHD in Black patients, but neither of these comorbidities predicted strokes, reported Shivani Garg, MD, assistant professor of medicine at the University of Wisconsin in Madison.

“Our study was one of the first to highlight racial disparities in CVD subtypes, with a threefold higher stroke risk and 24-fold higher ischemic heart disease risk in Black patients with lupus. Compared to previous studies in Black populations, our study highlights different peak timing of early stroke and ischemic heart disease in our cohort,“ she said at a plenary session during the virtual annual meeting of the American College of Rheumatology.

The study is one of the first to identify specific and unique SLE disease-related predictors of stroke and ischemic heart disease, she said.

Georgia Lupus Registry data

Dr. Garg and colleagues at the University of Wisconsin and Emory University in Atlanta drew on data from the Georgia Lupus Registry, a population-based registry of SLE patients from the Atlanta area. They identified patients diagnosed from 2002 through 2004 who had four or more ACR criteria for SLE, or three or more criteria plus a final diagnosis of SLE made by their board-certified rheumatologists.

The patients were matched to the Georgia Hospital Discharge Database and National Death Index from 2000 through 2013, with stroke- and IHD-related hospitalizations and deaths classified by the first three admission codes or cause-of-death codes.

Patients with transient ischemic attacks were included in the stroke category, and those with myocardial infarction and angina were included in the IHD category.

They identified 336 patients, 87% of whom were female, and 75% of whom were Black. The mean age at SLE diagnosis was 40 years. Among this cohort, there were 38 stroke-related events or deaths and 25 IHD-related events or deaths recorded from the period 2 years before through 14 years after an SLE diagnosis.
 

Early stroke, late IHD

The investigators first looked at the timing of stroke vs. IHD and found that a disproportionately high percentage of stroke events occurred in the second year after SLE diagnosis, whereas the peak of IHD-related events occurred in the 14^th year after diagnosis.

They then performed a race-stratified Cox proportional hazard analysis, and found a threefold higher risk for stroke in Black patients versus non-Black patients (P = .007) and a 24-fold higher risk for IHD (P < .0001).

In multivariate analysis, significant predictors of stroke were Black race with a hazard ratio (HR) of 3.4 (P = .028), discoid rash (HR, 4.6; P = .0028), and renal disorder (HR, 2.4; P = .04). However, stroke was not predicted by age, sex, immunologic disorder, serositis, hematologic disorder, or ACR criteria total greater than four.

Significant predictors of IHD included age 65 and older (HR, 61; P = .0007), Black race (HR, 24; P = .004), neurologic disorder (HR, 4.0; P = .018), and immunologic disorder (HR, 4.7; P = .02). But IHD could not be predicted by oral ulcers, discoid rash, or ACR criteria more than four.

“In future studies, we will examine mechanisms that drive the different timing and predictors of CVD subtypes and disparities. We will also examine the impact of timely prevention in high-risk SLE subsets,” Dr. Garg said.
 

Managing CVD risk

Angus Worthing, MD, from Arthritis & Rheumatism Associates in Chevy Chase, Md., and Washington, D.C., who moderated a press briefing where Dr. Garg discussed her data, routinely treats patients of different racial backgrounds with lupus. When asked how he manages patients with SLE and suspected cardiovascular complications, Dr. Worthing said, “I tend to, in my practice – and these kinds of studies may change what I do – watch for symptoms that might reflect coronary artery disease or cerebrovascular disease, potentially looking at the smaller arteries in the hands and feet as clues, and I will refer promptly to a vascular surgery expert or cardiologist for screening,” he said.

Dr. Garg added that in her practice, she and colleagues treat high-risk subsets of patients, such as those with lupus nephritis or multiple comorbidities, with aggressive blood pressure control and monitoring, as well as smoking cessation recommendations and lipid monitoring. They also try to limit or, if possible, decrease steroid doses to reduce risk for cardiovascular side effects.

Support for the study came in part from the U.S. Centers for Disease Control and Prevention. Dr. Garg and Dr. Worthing reported having no relevant disclosures.

They identified patients diagnosed from 2002 through 2004 who had four or more ACR criteria for SLE, or three or more criteria plus a final diagnosis of SLE made by their board-certified rheumatologists.

The patients were matched to the Georgia Hospital Discharge Database and National Death Index from 2000 through 2013, with stroke- and IHD-related hospitalizations and deaths classified by the first three admission codes or cause-of-death codes.

Patients with transient ischemic attacks were included in the stroke category, and those with myocardial infarction and angina were included in the IHD category.

They identified 336 patients, 87% of whom were female, and 75% of whom were Black. The mean age at SLE diagnosis was 40 years. Among this cohort, there were 38 stroke-related events or deaths and 25 IHD-related events or deaths recorded from the period 2 years before through 14 years after an SLE diagnosis.
 

Early stroke, late IHD

The investigators first looked at the timing of stroke vs. IHD and found that a disproportionately high percentage of stroke events occurred in the second year after SLE diagnosis, whereas the peak of IHD-related events occurred in the 14^th year after diagnosis.

They then performed a race-stratified Cox proportional hazard analysis, and found a threefold higher risk for stroke in Black patients versus non-Black patients (P = .007) and a 24-fold higher risk for IHD (P < .0001).

In multivariate analysis, significant predictors of stroke were Black race with a hazard ratio (HR) of 3.4 (P = .028), discoid rash (HR, 4.6; P = .0028), and renal disorder (HR, 2.4; P = .04). However, stroke was not predicted by age, sex, immunologic disorder, serositis, hematologic disorder, or ACR criteria total greater than four.

Significant predictors of IHD included age 65 and older (HR, 61; P = .0007), Black race (HR, 24; P = .004), neurologic disorder (HR, 4.0; P = .018), and immunologic disorder (HR, 4.7; P = .02). But IHD could not be predicted by oral ulcers, discoid rash, or ACR criteria more than four.

“In future studies, we will examine mechanisms that drive the different timing and predictors of CVD subtypes and disparities. We will also examine the impact of timely prevention in high-risk SLE subsets,” Dr. Garg said.
 

Managing CVD risk

Angus Worthing, MD, from Arthritis & Rheumatism Associates in Chevy Chase, Md., and Washington, D.C., who moderated a press briefing where Dr. Garg discussed her data, routinely treats patients of different racial backgrounds with lupus. When asked how he manages patients with SLE and suspected cardiovascular complications, Dr. Worthing said, “I tend to, in my practice – and these kinds of studies may change what I do – watch for symptoms that might reflect coronary artery disease or cerebrovascular disease, potentially looking at the smaller arteries in the hands and feet as clues, and I will refer promptly to a vascular surgery expert or cardiologist for screening,” he said.

Dr. Garg added that in her practice, she and colleagues treat high-risk subsets of patients, such as those with lupus nephritis or multiple comorbidities, with aggressive blood pressure control and monitoring, as well as smoking cessation recommendations and lipid monitoring. They also try to limit or, if possible, decrease steroid doses to reduce risk for cardiovascular side effects.

Support for the study came in part from the U.S. Centers for Disease Control and Prevention. Dr. Garg and Dr. Worthing reported having no relevant disclosures.

Patients with systemic lupus erythematosus (SLE) who received transcutaneous auricular vagus nerve stimulation (taVNS) had a clinically significant reduction in musculoskeletal pain when compared with those who received sham stimulation during a brief pilot trial.

“Our study population included individuals with significant pain and exemplifies the unmet need for adequate control of pain and fatigue in SLE. Importantly, this was a double-blind, sham-controlled study and neither the subject nor assessor was aware of a subject’s intervention. Objective outcomes, that is, tender and swollen joint counts, were also significantly reduced in subjects receiving taVNS, compared with those receiving [sham stimulation]. The stimulation was well tolerated with no adverse events attributed to the intervention, and, clinical benefits continued after taVNS was stopped,” first author Cynthia Aranow, MD, and her colleagues at the Feinstein Institutes for Medical Research in Manhasset, N.Y., wrote in Annals of the Rheumatic Diseases.

Stimulation of the vagus nerve can be achieved through the ear via its auricular branch, which innervates the cymba concha in the outer ear. Past pilot studies of implanted VNS devices lasting 6 weeks to 6 months in patients with Crohn’s disease or rheumatoid arthritis have shown improvements in measures of disease activity as well as objective markers of inflammation, and a more recent trial testing a transcutaneous devices’s effect in patients with Sjögren’s syndrome found significant reductions in fatigue over a 26-day period, the investigators noted.

In the taVNS device study, the researchers recruited 18 patients with SLE who had musculoskeletal pain rated as 4 or higher on a 10-cm visual analog scale and randomized them in a 2:1 ratio to receive taVNS once per day for 5 minutes for 4 consecutive days versus sham stimulation. Patients were allowed to be on stable doses of disease-modifying antirheumatic drugs, biologics, and/or prednisone ≤ 10 mg/day, with no change of dose within 28 days prior to baseline. The study excluded patients who used tobacco or an anticholinergic medication and those with a diagnosis of fibromyalgia.

The 12 patients who received actual taVNS had a significantly greater reduction in their pain, compared with 6 sham-treated patients (–5.00 vs. 0.10; P = .049), with 10 of 12 and 1 of 6 having a clinical response (a reduction of at least 1.58 on a 10-cm visual analog scale from baseline to day 5). Stimulation-treated patients also reported significantly greater reductions in fatigue, with 10 of 12 achieving a meaningful reduction, defined as a 4-point improvement on the Functional Assessment of Chronic Illness Therapy Fatigue Subscale; none of the sham-treated patients experienced meaningful improvement of fatigue. The patients who received taVNS had resolution of all swollen and tender joints, compared with 5.3% of tender and 9.1% of swollen joints in sham-treated patients. Ex vivo lipopolysaccharide stimulation of whole-blood samples from taVNS-treated patients, however, showed no reductions of inflammatory mediators or chemokines in tests on day 5 and day 12.

The investigators reported that there were no adverse events attributed to taVNS, including no reports of headache, lightheadedness, tinnitus, ear irritation, or changes to the external skin of the outer ear.

The study was supported by a grant from the John and Marcia Goldman Foundation. One author reported a financial relationship with Set Point Medical and My String, and three authors reported having a provisional patent application titled “Auricular stimulation device, system and methods of use.”

New data document the global fallout for rheumatology patients when hydroxychloroquine (HCQ) supplies were being diverted to hospitals for COVID-19 patients.

Demand for HCQ soared on evidence-lacking claims that the drug was effective in treating and preventing SARS-CoV-2 infection. Further research has since shown HCQ to be ineffective for COVID-19 and potentially harmful to patients.

But during the height of the COVID-19-related hype, patients worldwide with autoimmune diseases, particularly lupus and rheumatoid arthritis, had trouble getting the pills at all or couldn’t get as many as they needed for their chronic conditions.

Emily Sirotich, MSc, a PhD student at McMaster University in Hamilton, Ont., presented data at the virtual annual meeting of the American College of Rheumatology demonstrating that the severity of shortages differed widely.

Whereas 26.7% of rheumatology patients in Africa and 21.4% in southeast Asia said their pharmacy ran short of HCQ – which was originally developed as an antimalarial drug but has been found effective in treating some rheumatic diseases – only 6.8% of patients in the Americas and 2.1% in European regions reported the shortages.

“There are large regional disparities in access to antimalarials whether they were caused by the COVID-19 pandemic or already existed,” she said in an interview.

Global survey polled patient experience

Ms. Sirotich’s team analyzed data from the Global Rheumatology Alliance Patient Experience Survey.

They found that from 9,393 respondents (average age 46.1 years and 90% female), 3,872 (41.2%) were taking antimalarials. Of these, 230 (6.2% globally) were unable to keep taking the drugs because their pharmacy ran out.

Researchers evaluated the effect of drug shortages on disease activity, mental health, and physical health by comparing mean values with two-sided independent t-tests to identify significant differences.

They found that patients who were unable to obtain antimalarials had significantly higher levels of rheumatic disease activity as well as poorer mental and physical health (all P < .001).

The survey was distributed online through patient support groups and on social media. Patients with rheumatic diseases or their parents anonymously entered data including their rheumatic disease diagnosis, medications, COVID-19 status, and disease outcomes.

Ms. Sirotich said they are currently gathering new data to see if the gaps in access to HCQ persist and whether the physical and mental consequences of not having the medications continue.

Hospitals stockpiled HCQ in the U.S.

Michael Ganio, PharmD, senior director of pharmacy practice and quality at the American Society of Health-System Pharmacists (ASHP), said in an interview that hospitals in the United States received large amounts of HCQ in late spring and early summer, donated by pharmaceutical companies for COVID-19 before the lack of evidence for efficacy became clear.

Hospitals found themselves sitting on large quantities of HCQ they couldn’t use while prescriptions for rheumatology outpatients were going unfilled.

It is only in recent months that the U.S. Department of Health and Human Services has given clear direction to hospitals on how to redistribute those supplies, Dr. Ganio said.

“There’s no good real good way to move a product from a hospital to a [drug store] down the street,” he said.

The Food and Drug Administration now lists the HCQ shortages as resolved.
 

Declined prescriptions have frustrated physicians

Brett Smith, DO, a pediatric and adult rheumatologist in Alcoa, Tenn., said he was frustrated by pharmacies declining his prescriptions for HCQ for patients with rheumatoid arthritis.

“I got notes from pharmacies that I should consider alternative agents,” he said in an interview. But the safety profiles of the alternatives were not as good, he said.

“Hydroxychloroquine has no risk of infection and no risk of malignancy, and they were proposing alternative agents that carry those risks,” he said.

“I had some people with RA who couldn’t get [HCQ] who had a substantial increase in swollen joints and pain without it,” he said.

Dr. Smith said some patients who use HCQ for off-label uses such as certain skin disorders still aren’t getting the drug, as off-label use has been discouraged to make sure those with lupus and RA have enough, he said.

Saira Sheikh, MD, director of the University of North Carolina Rheumatology Lupus Clinic in Chapel Hill, said in an interview that during the summer months pharmacists required additional documentation of the diagnosis of autoimmune disease, resulting in unnecessary delays even when patients had been on the medication for many years.

She said emerging research has found patient-reported barriers to filling prescriptions, interruptions in HCQ treatment, and reported emotional stress and anxiety related to medication access during the COVID-19 pandemic.

“This experience with HCQ during the COVID-19 pandemic teaches us that while swift action and progress to address the immediate threats of the pandemic should be commended, it is important that we move forward in a conscious manner, guided by an evidence base that comes from high-quality research, not from rushed judgments based on preliminary studies, or pressure from political leaders,” Dr. Sheikh said.

Ms. Sirotich, Dr. Smith, Dr. Sheikh, and Dr. Ganio have disclosed no relevant financial relationships.

Last month, the American College of Rheumatology joined with 11 other medical associations and disease societies asking health insurance giant UnitedHealthcare (UHC) to not proceed with its proposed copay accumulator medical benefit program.

Copay accumulators are policies adopted by insurance companies or their pharmacy benefit managers to exclude patient copayment assistance programs for high-cost drugs, which are promulgated by the drug manufacturers, from being applied to a patient’s annual deductibles or out-of-pocket maximums. The manufacturer’s copay assistance, such as in the form of coupons, is designed to minimize the patient’s out-of-pocket costs. But insurers believe manufacturers will have no pressure to lower the prices of expensive specialty drugs unless patients are unable to afford them. Copay accumulators thus are aimed at giving insurers more leverage in negotiating prices for high-cost drugs.

UHC issued its new copay accumulator protocol for commercial individual and fully insured group plans in early October, effective Jan. 1, 2021, “in order to align employer costs for specialty medications with actual member out of pocket and deductibles,” according to the company’s announcement. In other words, patients will need to pay a higher share of the costs of these medications, said rheumatologist Christopher Phillips, MD, who chairs the Insurance Subcommittee of ACR’s Rheumatologic Care Committee. The annual price of biologic therapies for rheumatologic conditions ranges from $22,000 to $44,000, according to a recent press release from ACR.

The copay accumulator will negate the benefits of manufacturers’ copayment assistance programs for the patient, shifting more of the cost to the patient. With patients being forced to pay a higher share of drug costs for expensive biologic treatments for rheumatoid arthritis, lupus, and other rheumatologic conditions, they’ll stop taking the treatments, Dr. Phillips said.

“In my solo rheumatology practice in Paducah, Kentucky, when I’ve seen this kind of program applied on the pharmacy benefit side, rather than the medical benefit side, almost uniformly patients stop taking the high-cost treatments.” That can lead to disease flares, complications, and permanent disability. The newer rheumatologic drugs can cost $500 to $1,000 per treatment, and in many cases, there’s no generic or lower-cost alternative, he says. “We see policies like this as sacrificing patients to the battle over high drug prices. It’s bad practice, bad for patient outcomes, and nobody – apart from the payer – benefits.”

In ACR’s 2020 Rheumatic Disease Patient Survey, nearly half of 1,109 online survey respondents who had rheumatic diseases reported out-of-pocket costs greater than $1,000 per year for treatment. An IQVIA report from 2016 found that one in four specialty brand prescriptions are abandoned during the deductible phase, three times the rate seen when there is no deductible.

In an Oct. 7 letter to UHC, the 12 groups acknowledged that the drugs targeted by the accumulator policy are expensive. “However, they are also vitally important for our patients.” In addition to the ACR, the organizations involved include the AIDS Institute, American Academy of Dermatology Association, American Academy of Neurology, American College of Gastroenterology, American Gastroenterological Association, American Kidney Fund, Arthritis Foundation, Association for Clinical Oncology, Cancer Support Community, Coalition of State Rheumatology Organizations, and National Multiple Sclerosis Society.

UHC did not reply to questions in time for publication.


 

First large-scale payer to try copay accumulator program

Under UHC’s proposed policy, providers will be required to use UHC’s portal to report payment information received from drug manufacturer copay assistance programs that are applied to patients’ cost share of these drugs through a complex, 14-step “coupon submission process” involving multiple technology interfaces. “My first oath as a physician is to do no harm to my patient. Many of us are concerned about making these reports, which could harm our patients and undermine the doctor-patient relationship,” Dr. Phillips said.

“If I don’t report, what happens? I don’t think we know the answer to that. Some of us may decide we need to part ways with UHC.” Others may decline to participate in the drug manufacturers’ coupon programs beyond simply informing patients that manufacturer assistance is available.

“We’ve watched these copay accumulator policies for several years,” he said. “Some of them are rather opaque, with names like ‘copay savings programs’ or ‘copay value programs.’ But we had not seen a large-scale payer try to do this until now. Let’s face it: If UHC’s policy goes through, you can count the days until we see it from others.”

The Department of Health & Human Services, in its May 2020 final federal “Notice of Benefit and Payment Parameters for 2021,” indicated that individual states have the responsibility to regulate copay accumulator programs. Five states have banned them or restricted their use for individual and small group health plans. Arizona, Illinois, Virginia, and West Virginia passed such laws in 2019, and Georgia did so earlier this year.

“In next year’s state legislative sessions, we’ll make it a priority to pursue similar laws in other states,” Dr. Phillips said. “I’d encourage rheumatologists to educate their patients on the issues and be active in advocating for them.”

Last month, the American College of Rheumatology joined with 11 other medical associations and disease societies asking health insurance giant UnitedHealthcare (UHC) to not proceed with its proposed copay accumulator medical benefit program.

Copay accumulators are policies adopted by insurance companies or their pharmacy benefit managers to exclude patient copayment assistance programs for high-cost drugs, which are promulgated by the drug manufacturers, from being applied to a patient’s annual deductibles or out-of-pocket maximums. The manufacturer’s copay assistance, such as in the form of coupons, is designed to minimize the patient’s out-of-pocket costs. But insurers believe manufacturers will have no pressure to lower the prices of expensive specialty drugs unless patients are unable to afford them. Copay accumulators thus are aimed at giving insurers more leverage in negotiating prices for high-cost drugs.

UHC issued its new copay accumulator protocol for commercial individual and fully insured group plans in early October, effective Jan. 1, 2021, “in order to align employer costs for specialty medications with actual member out of pocket and deductibles,” according to the company’s announcement. In other words, patients will need to pay a higher share of the costs of these medications, said rheumatologist Christopher Phillips, MD, who chairs the Insurance Subcommittee of ACR’s Rheumatologic Care Committee. The annual price of biologic therapies for rheumatologic conditions ranges from $22,000 to $44,000, according to a recent press release from ACR.

The copay accumulator will negate the benefits of manufacturers’ copayment assistance programs for the patient, shifting more of the cost to the patient. With patients being forced to pay a higher share of drug costs for expensive biologic treatments for rheumatoid arthritis, lupus, and other rheumatologic conditions, they’ll stop taking the treatments, Dr. Phillips said.

“In my solo rheumatology practice in Paducah, Kentucky, when I’ve seen this kind of program applied on the pharmacy benefit side, rather than the medical benefit side, almost uniformly patients stop taking the high-cost treatments.” That can lead to disease flares, complications, and permanent disability. The newer rheumatologic drugs can cost $500 to $1,000 per treatment, and in many cases, there’s no generic or lower-cost alternative, he says. “We see policies like this as sacrificing patients to the battle over high drug prices. It’s bad practice, bad for patient outcomes, and nobody – apart from the payer – benefits.”

In ACR’s 2020 Rheumatic Disease Patient Survey, nearly half of 1,109 online survey respondents who had rheumatic diseases reported out-of-pocket costs greater than $1,000 per year for treatment. An IQVIA report from 2016 found that one in four specialty brand prescriptions are abandoned during the deductible phase, three times the rate seen when there is no deductible.

In an Oct. 7 letter to UHC, the 12 groups acknowledged that the drugs targeted by the accumulator policy are expensive. “However, they are also vitally important for our patients.” In addition to the ACR, the organizations involved include the AIDS Institute, American Academy of Dermatology Association, American Academy of Neurology, American College of Gastroenterology, American Gastroenterological Association, American Kidney Fund, Arthritis Foundation, Association for Clinical Oncology, Cancer Support Community, Coalition of State Rheumatology Organizations, and National Multiple Sclerosis Society.

First large-scale payer to try copay accumulator program

Under UHC’s proposed policy, providers will be required to use UHC’s portal to report payment information received from drug manufacturer copay assistance programs that are applied to patients’ cost share of these drugs through a complex, 14-step “coupon submission process” involving multiple technology interfaces. “My first oath as a physician is to do no harm to my patient. Many of us are concerned about making these reports, which could harm our patients and undermine the doctor-patient relationship,” Dr. Phillips said.

“If I don’t report, what happens? I don’t think we know the answer to that. Some of us may decide we need to part ways with UHC.” Others may decline to participate in the drug manufacturers’ coupon programs beyond simply informing patients that manufacturer assistance is available.

“We’ve watched these copay accumulator policies for several years,” he said. “Some of them are rather opaque, with names like ‘copay savings programs’ or ‘copay value programs.’ But we had not seen a large-scale payer try to do this until now. Let’s face it: If UHC’s policy goes through, you can count the days until we see it from others.”

Abatacept’s safety as well as indicators of its potential efficacy in the treatment of patients with early diffuse cutaneous systemic sclerosis (dcSSc) were reinforced by newly reported results from the 6-month, open-label extension of the phase 2 ASSET trial.

“Exploratory outcome measures during the open-label extension, including the composite ACR CRISS [American College of Rheumatology Combined Response Index in diffuse cutaneous Systemic Sclerosis] score, indicate that abatacept [Orencia] might promote overall global improvement in these participants,” Lorinda Chung, MD, of Stanford (Calif.) University, and colleagues wrote in the Lancet Rheumatology.

To continue to determine the safety and efficacy of abatacept as a treatment for dcSSc, the researchers launched the open-label extension of the randomized, double-blind ASSET trial. After patients in ASSET completed 12 months of treatment with either 125 mg weekly of subcutaneous abatacept or placebo, they were invited to join the extension period. ASSET’s primary endpoint was the change in modified Rodnan Skin Score (mRSS) from baseline to 12 months.

Of the 88 patients who began the ASSET trial – half of which were assigned to the abatacept group and the other half to the placebo group – 33 and 34 transitioned to weekly open-label treatment with 125 mg of abatacept, respectively. In the trial’s primary endpoint at 12 months, mean improvement in mRSS with abatacept was –6.6 (standard deviation, 6.4), compared to –3.7 (SD, 7.6) with placebo.

All told, 32 patients in each group completed 18 months of treatment. Patients who received abatacept in both periods had even more improvement in mRSS score (–9.8 [SD, 8.1]), as did patients who received placebo and then abatacept (–6.3 [SD, 9.3]). After 12 months, 68% of patients (23 of 34) in the abatacept group had a 5-unit or greater improvement in mRSS, compared with 50% of patients (19 of 38) in the placebo group. After 18 months, that percentage went up to 72% (23 of 32) among patients who took abatacept in both periods and 65% (20 of 31) for those who received it only in the extension.

Although the median ACR CRISS score was significantly greater at 12 months with abatacept, compared with placebo, both groups improved during the open-label period. After 12 months, an ACR CRISS score of 0.60 or higher was achieved by 55% (18 of 33) of the abatacept group and 36% (13 of 36) of the placebo group. In the extension, those percentages leapt to 66% (19 of 29) and 50% (13 of 26), respectively.

Throughout the double-blind phase, adverse events – including infectious events, serious events, and those that led to study withdrawal – were more frequent with placebo than with abatacept. During the extension period, although adverse events occurred slightly more among 18-month abatacept users, they ultimately occurred in fewer participants than in the double-blind phase.

Time to push forward with additional studies on abatacept

The results fortified by this open-label extension from Dr. Chung and colleagues should lay the groundwork for a phase 3 study on treatment with abatacept, wrote Francesco Del Galdo, MD, PhD, of the University of Leeds (England), in an accompanying editorial.

Along with clinically important improvements in several key measures, Dr. Del Galdo restated the value of abatacept’s “very benign” safety profile over the 18-month study period. However, he also acknowledged the “absence of concurrent immunosuppression” in the ASSET trial, noting that there is not yet a record of combination therapy safety across the board.

Beyond safety, he wondered if perhaps the time has passed for a placebo arm in dcSSc patients. He noted that participants in the initial placebo group were more likely to have “clinically relevant worsening of disease that required escape treatment,” which could make it ethically and analytically difficult to justify placebo.

The authors acknowledged the extension’s limitations, including the possibility that the survivors of the 12-month trial who joined the extension were more responsive to treatment or suffered from less severe disease. In addition, they noted that the study “was not powered for formal statistical comparison of the two treatment arms,” meaning all open-label results are considered exploratory. Finally, the number of participants in the extension period was small and likely contributed to low rates of adverse events, such as infection.

The trial was funded by Bristol-Myers Squibb, which markets abatacept, and the National Institutes of Health. The authors reported numerous potential conflicts of interest, including receiving grants, clinical trial support, and personal fees from various organizations and pharmaceutical companies, as well as serving on the advisory boards for such companies. Dr. Del Galdo reported receiving consultancy fees and research grants from several pharmaceutical companies.

Fully 48% of patients with autoimmune rheumatic diseases who developed persistent hypogammaglobulinemia after initiating treatment with immunomodulatory agents harbored gene variants associated with inborn errors of immunity, according to the findings of a single-center study published in Annals of the Rheumatic Diseases.

The results raise the possibility of a shared genetic etiology between “primary” and “secondary” hypogammaglobulinemia and suggest that some cases of autoimmune rheumatic disease may result from inborn errors of immunity. “In other words, a rheumatologist may be treating the rheumatic manifestations of a primary immunodeficiency disorder,” the study’s lead author, Georgios Sogkas, MD, PhD, said in an interview.

‘Striking’ findings suggest a future in personalized medicine

Experts who were not involved in the study called the results noteworthy. “The fact that half of patients with rheumatic disease who developed secondary hypogammaglobulinemia were found to have a functionally relevant mutation in a known PID gene is striking, albeit purely circumstantial given the absence of any functional or mechanistic data,” said Michael J. Ombrello, MD, principal investigator and head of the translational genetics and genomics unit at the National Institute of Arthritis and Musculoskeletal and Skin Diseases, who was not involved in the study.

The findings, if they are validated by additional studies, might help clinicians personalize medicine by avoiding hypogammaglobulinemia-inducing immunomodulatory regimens in genetically predisposed patients, or by targeting Janus kinase (JAK) inhibitor therapy for patients with STAT3 gain-of-function variants, or PI3K delta inhibitors for patients with variants leading to hyperactivation of the PI3Kdelta gene, Dr. Sogkas said.

Dr. Ombrello agreed: “Whether the hypogammaglobulinemia is classified as primary or secondary, the presence of these genetic variants in half of patients with hypogammaglobulinemia suggests an opportunity to improve clinical care. Although far off at this point, one can imagine a day where genetic data allows a rheumatologist to identify new-onset rheumatic disease patients carrying PID gene mutations and cater their therapy and monitoring accordingly.”

If further research validates these findings, they would add to a growing body of support for incorporating expanded or universal exome or genome sequencing in the care of medically complex patients, such as those with rheumatic diseases, Dr. Ombrello said. However, he cautioned that the investigators could have “overstated” the relationship in their study between secondary hypogammaglobulinemia and immunomodulatory treatment. The fact that a small group of study participants (about 7%) developed hypogammaglobulinemia after initiating immunomodulatory therapy does not confirm a causal relationship, he emphasized. Common variable immune deficiency (CVID) can develop in adults as late as the fifth and sixth decade of life, he noted, making it “not implausible that a small number of rheumatic disease patients would develop CVID while under the care of a rheumatologist. Would these patients have developed hypogammaglobulinemia even without treatment with immunomodulators, purely related to their genetic mutations? If so, they would be better classified as having primary immune deficiency, although that distinction is largely one of semantics.”

‘Rheumatologists are obliged to step up’

Interestingly, only 23% of the patients with hypogammaglobulinemia in the study had a clinically significant history of infections even though only 9% were receiving prophylactic antibiotics. Such findings highlight the complexity of PIDs, according to experts. “A long generation ago, we thought of immunodeficiencies as infections. Now we see them as autoimmune diseases, inflammatory diseases, allergic diseases – the spectrum continues to enlarge,” said Leonard H. Calabrese, DO, the RJ Fasenmyer chair of clinical immunology at the Cleveland Clinic, who was not involved in the study.

Dr. Calabrese noted that more than 450 monogenic variants have been linked to inborn errors of immunity. “Because these [PIDs] can mimic autoinflammatory presentations, rheumatologists are obliged to step up and gain a greater understanding, to be able to recognize and diagnose them and sort them out.”

Future goals should include quantifying the prevalence of genetic variants underlying hypogammaglobulinemia among patients with rheumatic diseases, and better characterizing outcomes and phenotypes of patients harboring variants linked to inborn errors of immunity, Dr. Sogkas said. “Whether these patients actually have a different disease than what they are being treated for, I can’t tell from this paper, and that’s an important question for the future,” added Dr. Calabrese. “I also do wonder about the effects of different drugs,” he said, noting that many patients with PID-associated autosomal gene variants developed persistent secondary hypogammaglobulinemia after initiating methotrexate. “It makes me wonder whether some of these genes have a specific interaction with methotrexate,” he said. “That could be a biomarker for drug toxicity.”

Study funders included the German Research Foundation, the German multiorgan Autoimmunity Network, Hannover Medical School, the Rosemarie-Germscheid Foundation, the German Academic Exchange Service, HBRS, the Center for Infection Biology, and the German Center for Infection Research. The investigators reported having no competing interests.

Such findings highlight the complexity of PIDs, according to experts. “A long generation ago, we thought of immunodeficiencies as infections. Now we see them as autoimmune diseases, inflammatory diseases, allergic diseases – the spectrum continues to enlarge,” said Leonard H. Calabrese, DO, the RJ Fasenmyer chair of clinical immunology at the Cleveland Clinic, who was not involved in the study.

Dr. Calabrese noted that more than 450 monogenic variants have been linked to inborn errors of immunity. “Because these [PIDs] can mimic autoinflammatory presentations, rheumatologists are obliged to step up and gain a greater understanding, to be able to recognize and diagnose them and sort them out.”

Future goals should include quantifying the prevalence of genetic variants underlying hypogammaglobulinemia among patients with rheumatic diseases, and better characterizing outcomes and phenotypes of patients harboring variants linked to inborn errors of immunity, Dr. Sogkas said. “Whether these patients actually have a different disease than what they are being treated for, I can’t tell from this paper, and that’s an important question for the future,” added Dr. Calabrese. “I also do wonder about the effects of different drugs,” he said, noting that many patients with PID-associated autosomal gene variants developed persistent secondary hypogammaglobulinemia after initiating methotrexate. “It makes me wonder whether some of these genes have a specific interaction with methotrexate,” he said. “That could be a biomarker for drug toxicity.”

Study funders included the German Research Foundation, the German multiorgan Autoimmunity Network, Hannover Medical School, the Rosemarie-Germscheid Foundation, the German Academic Exchange Service, HBRS, the Center for Infection Biology, and the German Center for Infection Research. The investigators reported having no competing interests.

Fully 48% of patients with autoimmune rheumatic diseases who developed persistent hypogammaglobulinemia after initiating treatment with immunomodulatory agents harbored gene variants associated with inborn errors of immunity, according to the findings of a single-center study published in Annals of the Rheumatic Diseases.

The results raise the possibility of a shared genetic etiology between “primary” and “secondary” hypogammaglobulinemia and suggest that some cases of autoimmune rheumatic disease may result from inborn errors of immunity. “In other words, a rheumatologist may be treating the rheumatic manifestations of a primary immunodeficiency disorder,” the study’s lead author, Georgios Sogkas, MD, PhD, said in an interview.

‘Striking’ findings suggest a future in personalized medicine

Experts who were not involved in the study called the results noteworthy. “The fact that half of patients with rheumatic disease who developed secondary hypogammaglobulinemia were found to have a functionally relevant mutation in a known PID gene is striking, albeit purely circumstantial given the absence of any functional or mechanistic data,” said Michael J. Ombrello, MD, principal investigator and head of the translational genetics and genomics unit at the National Institute of Arthritis and Musculoskeletal and Skin Diseases, who was not involved in the study.

The findings, if they are validated by additional studies, might help clinicians personalize medicine by avoiding hypogammaglobulinemia-inducing immunomodulatory regimens in genetically predisposed patients, or by targeting Janus kinase (JAK) inhibitor therapy for patients with STAT3 gain-of-function variants, or PI3K delta inhibitors for patients with variants leading to hyperactivation of the PI3Kdelta gene, Dr. Sogkas said.

Dr. Ombrello agreed: “Whether the hypogammaglobulinemia is classified as primary or secondary, the presence of these genetic variants in half of patients with hypogammaglobulinemia suggests an opportunity to improve clinical care. Although far off at this point, one can imagine a day where genetic data allows a rheumatologist to identify new-onset rheumatic disease patients carrying PID gene mutations and cater their therapy and monitoring accordingly.”

If further research validates these findings, they would add to a growing body of support for incorporating expanded or universal exome or genome sequencing in the care of medically complex patients, such as those with rheumatic diseases, Dr. Ombrello said. However, he cautioned that the investigators could have “overstated” the relationship in their study between secondary hypogammaglobulinemia and immunomodulatory treatment. The fact that a small group of study participants (about 7%) developed hypogammaglobulinemia after initiating immunomodulatory therapy does not confirm a causal relationship, he emphasized. Common variable immune deficiency (CVID) can develop in adults as late as the fifth and sixth decade of life, he noted, making it “not implausible that a small number of rheumatic disease patients would develop CVID while under the care of a rheumatologist. Would these patients have developed hypogammaglobulinemia even without treatment with immunomodulators, purely related to their genetic mutations? If so, they would be better classified as having primary immune deficiency, although that distinction is largely one of semantics.”

Few patient characteristics of men and women with nonradiographic axial spondyloarthritis (nr-axSpA) appear to differ, yet women with the condition have a significantly lower response rate to treatment with tumor necrosis factor (TNF) inhibitors, according to results from a prospective cohort study.

Despite these similarities between the sexes, first author Regula Neuenschwander of the department of rheumatology at Zurich University Hospital and colleagues reported in Arthritis Research & Therapy that women treated with a TNF inhibitor were 81% less likely than men to have a 40% or greater improvement on Assessment of Spondyloarthritis International Society (ASAS) response criteria by 1 year. Statistically significant differences at baseline included women’s longer time to nr-axSpA diagnosis, slightly lower HLA-B27 positivity rate, higher mean baseline Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score, higher rate of current enthesitis, and lower mean body mass index (BMI).

With radiographic disease, women have been reported to more often “present with higher self-reported disease activity and functional impairment, a lower quality of life, less severe spinal radiographic changes, and more peripheral disease (arthritis and enthesitis),” whereas men more often have “objective markers of inflammation, such as elevated C-reactive protein (CRP) levels and magnetic resonance imaging (MRI) inflammation of the axial skeleton,” the researchers wrote. Radiographic disease also tends to occur more often in men, and some studies have reported men to have a greater response to TNF inhibitors. However, the current study sought to understand whether these differences between sexes exist in patients with nonradiographic disease.

The researchers included 495 patients (231 men and 264 women) with a clinical diagnosis of nr-axSpA in the Swiss Clinical Quality Management cohort during 2005-2018 who fulfilled ASAS classification criteria for axSpA and lacked definite radiographic sacroiliac joint changes according to the modified New York criteria. The radiographs were centrally digitized and independently scored in a blinded manner by a rotating group of two readers (out of six total).

Both women and men had a mean age of around 28 years at symptom onset, but women had a significantly longer diagnostic delay of 6.0 years vs. 4.7 years. Also, women were significantly less likely to be HLA-B27 positive (67.0% vs. 76.5%) and had a significantly higher mean BASDAI score at baseline (5.3 vs. 4.6). More women than men also showed signs of current enthesitis (79.6% vs. 64.0%), and women had a lower mean BMI (24.3 vs. 25.7 kg/m²). Concomitant clinically diagnosed fibromyalgia was higher in women than in men (13.1% vs. 2.7%), and when patients with fibromylagia (n = 25) were excluded the remaining differences in BASDAI were mainly because of fatigue and enthesitis, both of which occurred more often in women than in men.

A total of 163 patients without fibromyalgia started a first TNF inhibitor, and 120 had a follow-up visit at 1 year. An ASAS40 response is defined as 40% improvement in at least three of four domains on the ASAS response criteria: patient global assessment of disease activity for the past week, patient assessment of back pain over the past week, function (as assessed on the Bath Ankylosing Spondylitis Functional Index [BASFI]), and inflammation (mean of BASDAI questions 5 and 6). An ASAS40 response was achieved by 17% of women and 38% of men (odds ratio, 0.34; 95% confidence interval, 0.12-0.93), and this difference became more pronounced after adjustment for baseline differences in BASDAI, Maastricht Ankylosing Spondylitis Enthesitis Score, BMI, and diagnostic delay (OR, 0.19; 95% CI, 0.05-0.61). ASAS40 response rates were lower for patients with higher BMI but better for those with higher BASDAI levels. The researchers found comparable results when they excluded patients who stopped a TNF inhibitor because of other reasons for discontinuation and also when they counted patients who discontinued the TNF inhibitor because of remission as responders.

The sex difference in nr-axSpA patients’ treatment response to TNF inhibitors was even larger than the 56% lower odds the same group of researchers reported finding between women and men with radiographic disease in an earlier report, according to the new paper.

Given that this study and others in nr-axSpA patients have found higher remission rates to TNF inhibitor therapy in men versus women, the “current study therefore adds to available data to support the claim for future randomized controlled trials in axSpA to be sufficiently powered to detect potential sex differences,” the researchers said.

The authors acknowledged that a lack of MRI scans available for central scoring made it impossible to evaluate potential imaging misinterpretation, such as possible abnormalities mimicking mild sacroiliitis that have been reported to be more prevalent in women. It is also possible that some patients with fibromyalgia were missed because of screening for the condition by expert opinion of the treating rheumatologist “on a comorbidity questionnaire and not through fulfillment of classification criteria for fibromyalgia or via the use of a standardized fibromyalgia questionnaire,” they said.

The study was funded by the Stiftung für Rheumaforschung in Zurich. The Swiss Clinical Quality Management Foundation is supported by the Swiss Society of Rheumatology and by 11 pharmaceutical companies. Two study authors reported receiving consulting and/or speaking fees from some of those same companies.

Patients with systemic sclerosis have variable disease progression but often experience debilitating fatigue, pain, and digestive issues – and they’re extremely concerned about progressive organ damage, according to those who spoke at and provided input at a public meeting on patient-focused drug development for the disease.

The virtual meeting was part of the Food and Drug Administration’s Patient-Focused Drug Development (PFDD) initiative, which began in 2012 and aims to provide a systematic way for patients’ experiences, needs, and priorities to be “captured and meaningfully incorporated” into drug development and evaluation.
 

Patients rate their most impactful symptoms

Dinesh Khanna, MBBS, MSc, a rheumatologist who directs a scleroderma research program at the University of Michigan, Ann Arbor, attended the meeting after giving an opening presentation on the disease to FDA officials, patients, and other participants. In a later interview, he said that patients’ ratings of their most impactful symptoms was especially striking.

Raynaud’s phenomenon, digestive symptoms, and fatigue were the top three answers to a poll question that asked patients what symptom had the most significant impact on daily life, he noted, “and none of these are being [strongly] addressed right now [in clinical trials] apart from Raynaud’s phenomenon, for which there are some trials ongoing.”

He and other researchers are “struggling with what outcomes measures to use [in their studies],” said Dr. Khanna, the Frederick G.L. Huetwell Professor of Rheumatology at the University. “My takeaway from the meeting as a clinical trialist is that we should be paying close attention to the symptoms that patients tell us are the most important. We should be including these in our trial designs as secondary endpoints, if not primary endpoints. We have not done that [thus far], really.”

Approximately 200,000 patients in the United States have scleroderma, and approximately 75,000-80,000 of these patients have systemic scleroderma, or systemic sclerosis, Dr. Khanna said in his opening presentation. Each year, he estimates, about 6,000 new diagnoses of systemic sclerosis are made.

More than 200 people – patients, FDA officials, and others – participated in the PFDD meeting. Patients participated in one of two panels – one focused on health effects and daily impacts, and the other on treatments – or submitted input electronically. All were invited to answer poll questions.

Raj Nair, MD, one of eight FDA leaders attending the meeting, noted in closing remarks that the pain experienced by patients with systemic sclerosis includes severe pain from Raynaud’s phenomenon and pain caused by digital ulcers and by calcinosis. “We heard about how paralyzing the pain from calcinosis is, and that there are very few options for alleviating this pain,” said Dr. Nair, of the division of rheumatology and transplant medicine.

Another takeaway, he said, is that the “fatigue can be severe and debilitating, leading to days where it is impossible to get out of bed,” and that digestive symptoms can also be severe. “Reflux,” he noted, “requires significant medical intervention.”
 

Patients describe their experiences

Rosemary Lyons, diagnosed with scleroderma 35 years ago, explained that while her skin is no longer hardened, she is overly sensitive to fabrics and skin care products and has difficulty with sleeping and eating. She moved away from family in the Northeast to live in the South where the climate is warmer, but even on a 90-degree night she needs a blanket and two comforters to curb the cold and attempt to sleep.

Impaired gastrointestinal motility has made food her “biggest problem” for the past 10 years, and because of GI symptoms, she can eat only one meal a day. She also experiences fainting, brain fog, and severe fatigue. On a good day, Ms. Lyons noted, she sometimes opts to do some house chores “knowing that I’ll have 1-3 days of recovery.”

Another patient, Amy Harding, said that 22 years after her scleroderma diagnosis, “the calcinosis I get in my fingers, elbows, toes, and ears tops all the prior symptoms.” The skin tightening and digital ulcers that she experienced in the first 10 years have tapered off, and while Raynaud’s symptoms and heartburn have worsened, they are at least partly manageable with medications, unlike the pain from calcinosis.
 

Treating symptoms vs. disease may be key in risk-benefit analysis

In questions after patient presentations, FDA officials probed for more perspective on issues such as how fatigue should be assessed, the differences between fatigue and brain fog, the impact of calcinosis on functioning, and how much risk patients would be willing to assume from treatments that have side effects and that may or may not modulate the disease and slow disease progression.

Most patients said in response to an FDA poll question that they definitely (almost 40%) or possibly (almost 50%) would be willing to try a hypothetical new self-injectable medication if it were shown to reduce their most impactful symptoms but had side effects.

“I think what [we’ve been hearing] today is that whether we’re working on the symptoms or the disease itself is [the key]” to patients’ risk-benefit analysis, said meeting moderator Capt. Robyn Bent, RN, MS, of the U.S. Public Health Service, and director of the PFDD.

Anita Devine, diagnosed 13 years ago with systemic sclerosis, was one of several panel members who said she would accept more bothersome treatment side effects and risks “if the gain was control of disease progression and overall quality of life ... and organ preservation.” Ms. Devine, who has needed kidney dialysis and multiple hand surgeries, noted that she previously took anti-neoplastic and anti-inflammatory agents “to try to stem the course of my disease, but unfortunately the disease did not abate.”

Treatments for systemic sclerosis include vasodilators, immunosuppressive medications, antifibrotic therapies, and stem cell transplants, Dr. Khanna said in his opening remarks.

Trials of drugs for scleroderma have focused on early disease that may be amenable to treatment, with the exception of trials for pulmonary arterial hypertension, which affects some patients with systemic sclerosis. There are multiple FDA-approved drugs for pulmonary arterial hypertension and more trials are underway.

Outcomes such as pain and fatigue are included in many of the trials currently underway, but they tend to be lower-level secondary outcomes measures that cannot be incorporated into drug labeling or are more “exploratory in nature,” Dr. Khanna said in the interview.

Dr. Khanna disclosed that he is the chief medical officer (an equity position) for CiVi Biopharma/Eicos Sciences Inc., which is developing a drug for Raynaud’s, and serves as a consultant and grant recipient for numerous companies that make or are developing drugs for systemic sclerosis.

The FDA will accept patient comments until Dec. 15, 2020, at which time comments will be compiled into a summary report, Ms. Bent said.

Most patients said in response to an FDA poll question that they definitely (almost 40%) or possibly (almost 50%) would be willing to try a hypothetical new self-injectable medication if it were shown to reduce their most impactful symptoms but had side effects.

“I think what [we’ve been hearing] today is that whether we’re working on the symptoms or the disease itself is [the key]” to patients’ risk-benefit analysis, said meeting moderator Capt. Robyn Bent, RN, MS, of the U.S. Public Health Service, and director of the PFDD.

Anita Devine, diagnosed 13 years ago with systemic sclerosis, was one of several panel members who said she would accept more bothersome treatment side effects and risks “if the gain was control of disease progression and overall quality of life ... and organ preservation.” Ms. Devine, who has needed kidney dialysis and multiple hand surgeries, noted that she previously took anti-neoplastic and anti-inflammatory agents “to try to stem the course of my disease, but unfortunately the disease did not abate.”

Treatments for systemic sclerosis include vasodilators, immunosuppressive medications, antifibrotic therapies, and stem cell transplants, Dr. Khanna said in his opening remarks.

Trials of drugs for scleroderma have focused on early disease that may be amenable to treatment, with the exception of trials for pulmonary arterial hypertension, which affects some patients with systemic sclerosis. There are multiple FDA-approved drugs for pulmonary arterial hypertension and more trials are underway.

Outcomes such as pain and fatigue are included in many of the trials currently underway, but they tend to be lower-level secondary outcomes measures that cannot be incorporated into drug labeling or are more “exploratory in nature,” Dr. Khanna said in the interview.

Dr. Khanna disclosed that he is the chief medical officer (an equity position) for CiVi Biopharma/Eicos Sciences Inc., which is developing a drug for Raynaud’s, and serves as a consultant and grant recipient for numerous companies that make or are developing drugs for systemic sclerosis.

The FDA will accept patient comments until Dec. 15, 2020, at which time comments will be compiled into a summary report, Ms. Bent said.

Patients with systemic sclerosis have variable disease progression but often experience debilitating fatigue, pain, and digestive issues – and they’re extremely concerned about progressive organ damage, according to those who spoke at and provided input at a public meeting on patient-focused drug development for the disease.

The virtual meeting was part of the Food and Drug Administration’s Patient-Focused Drug Development (PFDD) initiative, which began in 2012 and aims to provide a systematic way for patients’ experiences, needs, and priorities to be “captured and meaningfully incorporated” into drug development and evaluation.
 

Patients rate their most impactful symptoms

Dinesh Khanna, MBBS, MSc, a rheumatologist who directs a scleroderma research program at the University of Michigan, Ann Arbor, attended the meeting after giving an opening presentation on the disease to FDA officials, patients, and other participants. In a later interview, he said that patients’ ratings of their most impactful symptoms was especially striking.

Raynaud’s phenomenon, digestive symptoms, and fatigue were the top three answers to a poll question that asked patients what symptom had the most significant impact on daily life, he noted, “and none of these are being [strongly] addressed right now [in clinical trials] apart from Raynaud’s phenomenon, for which there are some trials ongoing.”

He and other researchers are “struggling with what outcomes measures to use [in their studies],” said Dr. Khanna, the Frederick G.L. Huetwell Professor of Rheumatology at the University. “My takeaway from the meeting as a clinical trialist is that we should be paying close attention to the symptoms that patients tell us are the most important. We should be including these in our trial designs as secondary endpoints, if not primary endpoints. We have not done that [thus far], really.”

Approximately 200,000 patients in the United States have scleroderma, and approximately 75,000-80,000 of these patients have systemic scleroderma, or systemic sclerosis, Dr. Khanna said in his opening presentation. Each year, he estimates, about 6,000 new diagnoses of systemic sclerosis are made.

More than 200 people – patients, FDA officials, and others – participated in the PFDD meeting. Patients participated in one of two panels – one focused on health effects and daily impacts, and the other on treatments – or submitted input electronically. All were invited to answer poll questions.

Raj Nair, MD, one of eight FDA leaders attending the meeting, noted in closing remarks that the pain experienced by patients with systemic sclerosis includes severe pain from Raynaud’s phenomenon and pain caused by digital ulcers and by calcinosis. “We heard about how paralyzing the pain from calcinosis is, and that there are very few options for alleviating this pain,” said Dr. Nair, of the division of rheumatology and transplant medicine.

Another takeaway, he said, is that the “fatigue can be severe and debilitating, leading to days where it is impossible to get out of bed,” and that digestive symptoms can also be severe. “Reflux,” he noted, “requires significant medical intervention.”
 

Patients describe their experiences

Rosemary Lyons, diagnosed with scleroderma 35 years ago, explained that while her skin is no longer hardened, she is overly sensitive to fabrics and skin care products and has difficulty with sleeping and eating. She moved away from family in the Northeast to live in the South where the climate is warmer, but even on a 90-degree night she needs a blanket and two comforters to curb the cold and attempt to sleep.

Impaired gastrointestinal motility has made food her “biggest problem” for the past 10 years, and because of GI symptoms, she can eat only one meal a day. She also experiences fainting, brain fog, and severe fatigue. On a good day, Ms. Lyons noted, she sometimes opts to do some house chores “knowing that I’ll have 1-3 days of recovery.”

Another patient, Amy Harding, said that 22 years after her scleroderma diagnosis, “the calcinosis I get in my fingers, elbows, toes, and ears tops all the prior symptoms.” The skin tightening and digital ulcers that she experienced in the first 10 years have tapered off, and while Raynaud’s symptoms and heartburn have worsened, they are at least partly manageable with medications, unlike the pain from calcinosis.

A new study of immunoglobulin levels in adult patients with systemic lupus erythematosus (SLE) has found that acquired low levels of IgA are associated with a higher risk of infection.

To the knowledge of first author Ibrahim Almaghlouth, MD, of the division of rheumatology at the University of Toronto, and colleagues, “this is the first dedicated study to examine the relationship between acquired low immunoglobulins and infection risk in adult patients with SLE.” But as to whether there may be a “protective role for immunoglobulins and the potential effect of immunoglobulin replacement in a setting of recurrent or severe infection among SLE patients requires further study.”

To determine if the risk of infection was tied to acquired low immunoglobulin levels, the researchers launched a retrospective analysis of data from a prospective cohort study of adult SLE patients from a Toronto lupus cohort that was established in 1970. The study was published in Rheumatology.

A total of 448 patients with at least two low immunoglobulin tests were matched with 656 SLE patients with no low immunoglobulins according to enrollment decade. The average age of the low-immunoglobulin group was 41.8 years, compared with 39.3 years in the control group. Average disease duration was 11.2 years in the low-immunoglobulin group and 7.6 years in the control group.

Of the patients in the low-immunoglobulin group, 221 had consecutive low tests and 227 had nonconsecutive low tests. Overall, 98 of those patients had low IgG, 251 patients had low IgM, and 51 patients had low IgA. Only 48 patients had overlapping low levels, including 5 with all three.

Average levels among the low-immunoglobulin group at baseline were 11.5 (standard deviation, 6.1) g/L of IgG, 0.8 (1.1) g/L of IgM, and 2.4 (1.6) g/L of IgA, while average levels among the control group were 16.3 (6.4) g/L of IgG, 1.8 (1.2) g/L of IgM, and 3.2 (1.5) g/L of IgA. In the primary analysis, after adjustment using propensity scoring, there were 97 infections: 47 in the low-immunoglobulin group and 50 in the control group. The most common types were respiratory and urinary tract infections, and the rate of infection was higher in patients with low IgA. The IgA level associated with risk of infection was less than 0.75 g/L.

After Cox regression analysis, the only variable that significantly increased infection risk was a low IgA level (hazard ratio, 3.19; 95% confidence interval, 1.17-8.71), not a low IgG level (HR, 1.87; 95% CI, 0.77-4.54) or low IgM level (HR, 0.63; 95% CI, 0.34-1.17). In regard to recovery among the low-immunoglobulin group, 11 patients (2.5%) recovered from low immunoglobulins within in the first year, followed by 36 (8.2%) in the second year, 44 (10.1%) in the third year, and 80 (18.4%) in the fourth year. All told, 60% (263) of patients with acquired hypogammaglobulinemia recovered over a 4-year period.

Is there clinical relevance to low IgA?

“I don’t see us using this clinically immediately,” Karen Costenbader, MD, a rheumatologist at Brigham and Women’s Hospital and professor of medicine at Harvard Medical School, both in Boston, said in an interview. “We do test immunoglobulins often, especially in patients who’ve had biologic therapy. Will we start thinking about their IgA levels? It’s not clear, and the researchers leave it up in the air as to what this means, beyond them being at high risk.”

That said, she added, “IgA levels are interesting, especially in a time of COVID, because they’re associated with mucosal immunity. Is this subset of patients going to be at particularly high risk for the coronavirus?”

She also noted that, though immunoglobulin replacement has been helpful in her patients, it’s an expensive therapy to recommend for low IgA levels without knowing exactly what is causing these deficiencies. “My question is, would it be useful to follow these levels in lupus patients, even we don’t know what to do about them?” she asked. “We know there are a lot of risk factors for infections, so is the IgA going to be useful above and beyond that, and then what can we do about it?”

The authors acknowledged their study’s potential limitations, including low infection rates and yearly measurements of immunoglobulin levels, which could’ve led to misclassifying a lab error as true low immunoglobulin. They also highlighted its strengths, including using various methods to reduce selection and confounding bias while also reporting consistent results after examining multiple definitions of low immunoglobulins and outcomes.

The study received no specific funding, and the authors reported no potential conflicts of interest.
