Sotagliflozin, a novel agent that inhibits sodium-glucose cotransporter 1 as well as SGLT2, has received marketing approval from the Food and Drug Administration for reducing the risk for cardiovascular death, hospitalization for heart failure, and urgent heart failure visits in patients with heart failure, and also for preventing these same events in patients with type 2 diabetes, chronic kidney disease (CKD), and other cardiovascular disease risk factors.

This puts sotagliflozin in direct competition with two SGLT2 inhibitors, dapagliflozin (Farxiga) and empagliflozin (Jardiance), that already have indications for preventing heart failure hospitalizations in patients with heart failure as well as approvals for type 2 diabetes and preservation of renal function.

Officials at Lexicon Pharmaceuticals, the company that developed and will market sotagliflozin under the trade name Inpefa, said in a press release that they expect U.S. sales of the agent to begin before the end of June 2023. The release also highlighted that the approval broadly covered use in patients with heart failure across the full range of both reduced and preserved left ventricular ejection fractions.

Lexicon officials also said that the company will focus on marketing sotagliflozin for preventing near-term rehospitalizations of patients discharged after an episode of acute heart failure decompensation.

They base this niche target for sotagliflozin on results from the SOLOIST-WHF trial, which randomized 1,222 patients with type 2 diabetes recently hospitalized for worsening heart failure and showed a significant 33% reduction in the rate of deaths from cardiovascular causes and hospitalizations and urgent visits for heart failure, compared with control patients during a median 9 months of follow-up. Nearly half of the enrolled patients received their first dose while still hospitalized, while the other half received their first dose a median of 2 days after hospital discharge. The drug appeared safe.
 

Cutting heart failure rehospitalizations in half

An exploratory post hoc analysis of SOLOIST-WHF showed that treatment with sotagliflozin cut the rate of rehospitalizations roughly in half after both 30 and 90 days compared with control patients, according to an abstract presented at the 2022 annual scientific sessions of the AHA that has not yet been published in a peer-reviewed journal.

The only SGLT2 inhibitor tested so far when initiated in patients during hospitalization for heart failure is empagliflozin, in the EMPULSE trial, which randomized 530 patients. EMPULSE also showed that starting an SGLT2 inhibitor in this setting was safe and resulted in significant clinical benefit, the study’s primary endpoint, defined as a composite of death from any cause, number of heart failure events, and time to first heart failure event, or a 5-point or greater difference in change from baseline in the Kansas City Cardiomyopathy Questionnaire Total Symptom Score at 90 days.

In the DELIVER trial, which tested dapagliflozin in patients with heart failure with preserved ejection fraction, roughly 10% of patients started study treatment during or within 30 days of heart failure hospitalization, and in this subgroup, dapagliflozin appeared as effective as it was in the other 90% of patients who did not start the drug during an acute or subacute phase.

Despite the SOLOIST-WHF evidence for sotagliflozin’s safety and efficacy in this economically important clinical setting, some experts say the drug faces an uphill path as it contends for market share against two solidly established, albeit dramatically underused, SGLT2 inhibitors. (Recent data document that 20% or fewer of U.S. patients eligible for treatment with an SGLT2 inhibitor receive it, such as a review of 49,000 patients hospitalized during 2021-2022 with heart failure with reduced ejection fraction.)

Others foresee a clear role for sotagliflozin, particularly because of additional facets of the drug’s performance in trials that they perceive give it an edge over dapagliflozin and empagliflozin. This includes evidence that sotagliflozin treatment uniquely (within the SGLT2 inhibitor class) cuts the rate of strokes and myocardial infarctions, as well as evidence of its apparent ability to lower hemoglobin A1c levels in patients with type 2 diabetes and with an estimated glomerular filtration rate below 30 mL/min per 1.73 m², a property likely linked to inhibition of SGLT1 in the gut that dampens intestinal glucose absorption.
 

Sotagliflozin uptake ‘will be a challenge’

“It will be a challenge” for sotagliflozin uptake, given the head start that both dapagliflozin and empagliflozin have had as well-documented agents for patients with heart failure, commented Javed Butler, MD, a heart failure clinician and trialist who is president of the Baylor Scott & White Research Institute in Dallas.

Given the position dapagliflozin and empagliflozin currently have in U.S. heart failure management – with the SGLT2 inhibitor class called out in guidelines as foundational for treating patients with heart failure with reduced ejection fraction and likely soon for heart failure with preserved ejection fraction as well – “I can’t imagine [sotagliflozin] will be considered a preferred option,” Dr. Butler said in an interview.

Another expert was even more dismissive of sotagliflozin’s role.

“There is no persuasive evidence that sotagliflozin has any advantages, compared with the SGLT2 inhibitors, for the treatment of heart failure,” said Milton Packer, MD, a heart failure specialist and trialist at Baylor University Medical Center, Dallas. “I do not see why U.S. physicians might pivot from established SGLT2 inhibitors to sotagliflozin,” unless it was priced “at a very meaningful discount to available SGLT2 inhibitors.”

At the time it announced the FDA’s approval, Lexicon did not provide details on how it would price sotagliflozin. Existing retail prices for dapagliflozin and empagliflozin run about $550-$600/month, a price point that has contributed to slow U.S. uptake of the drug class. But experts anticipate a dramatic shake-up of the U.S. market for SGLT2 inhibitors with expected introduction of a generic SGLT2 inhibitor formulation by 2025, a development that could further dampen sotagliflozin’s prospects.

Other experts are more optimistic about the new agent’s uptake, perhaps none more than Deepak L. Bhatt, MD, MPH, who led both pivotal trials that provide the bulk of sotagliflozin’s evidence package.

In addition to SOLOIST-WHF, Dr. Bhatt also headed the SCORED trial, with 10,584 patients with type 2 diabetes, CKD, and risks for cardiovascular disease randomized to sotagliflozin or placebo and followed for a median of 16 months. The primary result showed that sotagliflozin treatment cut the combined rate of deaths from cardiovascular causes, hospitalizations for heart failure, and urgent visits for heart failure by a significant 26% relative to control patients.
 

A clear MACE benefit

“The data from SOLOIST-WHF and SCORED look at least as good as the data for the SGLT2 inhibitors for heart failure, and what appears to be different are the rates for MI and stroke in SCORED,” said Dr. Bhatt, director of Mount Sinai Heart, New York.

“I believe the rate of major adverse cardiovascular events [MACE] were reduced [in SCORED], and this is different from the SGLT2 inhibitors,” he said in an interview.

In 2022, Dr. Bhatt reported results from a prespecified secondary analysis of SCORED that showed that treatment with sotagliflozin cut the rate of MACE by a significant 21%-26%, compared with placebo. This finding was, in part, driven by the first data to show a substantial benefit from an SGLT inhibitor on stroke rates.

And while SCORED did not report a significant benefit for slowing progression of CKD, subsequent post hoc analyses have suggested this advantage also in as-yet-unpublished findings, Dr. Bhatt added.

But he said he doubted nephrologists will see it as a first-line agent for slowing CKD progression – an indication already held by dapagliflozin, pending for empagliflozin, and also in place for a third SGLT2 inhibitor, canagliflozin (Invokana) – because sotagliflozin lacks clear significant and prespecified evidence for this effect.

Dr. Bhatt also acknowledged the limitation of sotagliflozin compared with the SGLT2 inhibitors as an agent for glucose control, again because of no evidence for this effect from a prospective analysis and no pending indication for type 2 diabetes treatment. But the SCORED data showed a clear A1c benefit, even in patients with severely reduced renal function.
 

Mostly for cardiologists? ‘Compelling’ reductions in MIs and strokes

That may mean sotagliflozin “won’t get much use by endocrinologists nor by primary care physicians,” commented Carol L. Wysham, MD, an endocrinologist with MultiCare in Spokane, Wash.

Sotagliflozin “will be a cardiology drug,” and will “have a hard time” competing with the SGLT2 inhibitors, she predicted.

Dr. Bhatt agreed that sotagliflozin “will be perceived as a drug for cardiologists to prescribe. I don’t see endocrinologists, nephrologists, and primary care physicians reaching for this drug if it has a heart failure label.” But, he added, “my hope is that the company files for additional indications. It deserves an indication for glycemic control.”

The evidence for a heart failure benefit from sotagliflozin is “valid and compelling,” and “having this option is great,” commented Mikhail N. Kosiborod, MD, a cardiologist, vice president of research at Saint Luke’s Health System, and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo. But, he added, “it will be a reasonably tall task for sotagliflozin to come from behind and be disruptive in a space where there are already two well-established SGLT2 inhibitors” approved for preventing heart failure hospitalizations, “with a lot of data to back them up,”

The feature that sets sotagliflozin apart from the approved SGLT2 inhibitors is the “really compelling decrease” it produced in rates of MIs and strokes “that we simply do not see with SGLT2 inhibitors,” Dr. Kosiborod said in an interview.

He also cited results from SCORED that suggest “a meaningful reduction in A1c” when indirectly compared with SGLT2 inhibitors, especially in patients with more severe CKD. The lack of a dedicated A1c-lowering trial or an approved type 2 diabetes indication “will not be a problem for cardiologists,” he predicted, but also agreed that it is less likely to be used by primary care physicians in low-risk patients.

“I can see myself prescribing sotagliflozin,” said Dr. Kosiborod, a SCORED coinvestigator, especially for patients with coexisting type 2 diabetes, heart failure, CKD, and atherosclerotic cardiovascular disease. These patients may get “more bang for the buck” because of a reduced risk for MI and stroke, making sotagliflozin “a solid consideration in these patients if the economic factors align.”

Like others, Dr. Kosiborod cited the big impact pricing will have, especially if, as expected, a generic SGLT2 inhibitor soon comes onto the U.S. market. “Access and affordability are very important.”

SOLOIST-WHF and SCORED were sponsored initially by Sanofi and later by Lexicon after Sanofi pulled out of sotagliflozin development. Dr. Butler has been a consultant for Lexicon as well as for AstraZeneca (which markets Farxiga), Boehringer Ingelheim and Lilly (which jointly market Jardiance), and Janssen (which markets Invokana), as well as for numerous other companies. Dr. Packer has been a consultant for AstraZeneca, Boehringer Ingelheim, Lilly, and numerous other companies. Dr. Bhatt was lead investigator for SOLOIST-WHF and SCORED and has been an adviser for Boehringer Ingelheim and Janssen and numerous other companies. Dr. Wysham has been an adviser, speaker, and consultant for AstraZeneca, Boehringer Ingelheim, Lilly, Janssen, Novo Nordisk, and Sanofi, an adviser for Abbott, and a speaker for Insulet. Dr. Kosiborod was a member of the SCORED Steering Committee and has been a consultant for Lexicon, AstraZeneca, Boehringer Ingelheim, Janssen, Lilly, Novo Nordisk, and numerous other companies.

The lack of a dedicated A1c-lowering trial or an approved type 2 diabetes indication “will not be a problem for cardiologists,” he predicted, but also agreed that it is less likely to be used by primary care physicians in low-risk patients.

“I can see myself prescribing sotagliflozin,” said Dr. Kosiborod, a SCORED coinvestigator, especially for patients with coexisting type 2 diabetes, heart failure, CKD, and atherosclerotic cardiovascular disease. These patients may get “more bang for the buck” because of a reduced risk for MI and stroke, making sotagliflozin “a solid consideration in these patients if the economic factors align.”

Like others, Dr. Kosiborod cited the big impact pricing will have, especially if, as expected, a generic SGLT2 inhibitor soon comes onto the U.S. market. “Access and affordability are very important.”

People who followed a vegan or vegetarian diet had lower blood levels of low-density lipoprotein cholesterol (LDL-C), total cholesterol, and apolipoprotein B (apoB) than people who followed an omnivore diet, in a new meta-analysis of 30 trials.

The findings suggest that “plant-based diets have the potential to lessen the atherosclerotic burden from atherogenic lipoproteins and thereby reduce the risk of cardiovascular disease,” write Caroline Amelie Koch, a medical student at the University of Copenhagen, and colleagues. Their findings were published online in the European Heart Journal (2023 May 24. doi: 10.1093/eurheartj/ehad211).

“Vegetarian and vegan diets were associated with a 14% reduction in all artery-clogging lipoproteins as indicated by apoB,” senior author Ruth Frikke-Schmidt, DMSc, PhD, Rigshospitalet, Copenhagen, and professor, University of Copenhagen, said in a press release from her university.

“This corresponds to a third of the effect of taking cholesterol-lowering medications such as statins,” she added, “and would result in a 7% reduction in the risk of cardiovascular disease in someone who maintained a plant-based diet for 5 years.”

More support for vegan, vegetarian diets

These new findings “add to the body of evidence supporting favorable effects of healthy vegan and vegetarian dietary patterns on circulating levels of LDL-C and atherogenic lipoproteins, which would be expected to reduce ASCVD risk,” Kevin C. Maki, PhD, and Carol Kirkpatrick, PhD, MPH, write in an accompanying editorial.

“While it is not necessary to entirely omit foods such as meat, poultry, and fish/seafood to follow a recommended dietary pattern, reducing consumption of such foods is a reasonable option for those who prefer to do so,” note Dr. Maki, of Indiana University School of Public Health, Bloomington, and Kirkpatrick, of Idaho State University, Pocatello.
 

Plant-based diet needs to be ‘well-planned’

Several experts who were not involved in this meta-analysis shed light on the study and its implications in comments to the U.K. Science Media Center.

“Although a vegetarian and vegan diet can be very healthy and beneficial with respect to cardiovascular risk, it is important that it is well planned so that nutrients it can be low in are included, including iron, iodine, vitamin B12, and vitamin D,” said Duane Mellor, PhD, a registered dietitian and senior lecturer, Aston Medical School, Aston University, Birmingham, England.

Some people “may find it easier to follow a Mediterranean-style diet that features plenty of fruit, vegetables, pulses, wholegrains, fish, eggs and low-fat dairy, with only small amounts of meat,” Tracy Parker, senior dietitian at the British Heart Foundation, London, suggested.

“There is considerable evidence that this type of diet can help lower your risk of developing heart and circulatory diseases by improving cholesterol and blood pressure levels, reducing inflammation, and controlling blood glucose levels,” she added.

And Aedin Cassidy, PhD, chair in nutrition & preventative medicine, Queen’s University Belfast (Ireland), noted that “not all plant-based diets are equal. Healthy plant-based diets, characterized by fruits, vegetables, and whole grains improve health, but other plant diets (for example, those including refined carbohydrates, processed foods high in fat/salt, etc.) do not.”  

This new study shows that plant-based diets have the potential to improve health by improving blood lipids, “but this is one of many potential mechanisms, including impact on blood pressure, weight maintenance, and blood sugars,” she added.

“This work represents a well-conducted analysis of 30 clinical trials involving over two thousand participants and highlights the value of a vegetarian diet in reducing the risk of heart attack or stroke through reduction in blood cholesterol levels,” said Robert Storey, BM, DM, professor of cardiology, University of Sheffield, U.K.

However, it also demonstrates that the impact of diet on an individual’s cholesterol level is relatively limited, he added.

“This is because people inherit the tendency for their livers to produce too much cholesterol, meaning that high cholesterol is more strongly influenced by our genes than by our diet,” he explained.

This is “why statins are needed to block cholesterol production in people who are at higher risk of or have already suffered from a heart attack, stroke, or other illness related to cholesterol build-up in blood vessels.”
 

Beneficial effect on ApoB, LDL-C, and total cholesterol

ApoB is the main apolipoprotein in LDL-C (“bad” cholesterol), the researchers note. Previous studies have shown that LDL-C and apoB-containing particles are associated with increased risk of ASCVD.

They aimed to estimate the effect of vegetarian or vegan diets on blood levels of total cholesterol, LDL-C, triglycerides, and apoB in people randomized to a vegetarian or vegan diet versus an omnivorous diet (that is, including meat and dairy).

They identified 30 studies published between 1982 and 2022 and conducted in the United States (18 studies), Sweden (2), Finland (2), South Korea (2), Australia (1), Brazil (1), Czech Republic (1), Italy (1), Iran (1), and New Zealand (1).

The diet interventions lasted from 10 days to 5 years with a mean of 29 weeks (15 studies ≤ 3 months; 12 studies 3-12 months; and three studies > 1 year). Nine studies used a crossover design, and the rest used a parallel design whereby participants followed only one diet.

The studies had 11 to 291 participants (mean, 79 participants) with a mean BMI of 21.5-35.1 kg/m² and a mean age of 20-67 years. Thirteen studies included participants treated with lipid-lowering therapy at baseline.

The dietary intervention was vegetarian in 15 trials (three lacto-vegetarian and 12 lacto-ovo-vegetarian) and vegan in the other 15 trials.

On average, compared with people eating an omnivore diet, people eating a plant-based diet had a 7% reduction in total cholesterol from baseline (–0.34 mmol/L), a 10% reduction in LDL-C from baseline (–0.30 mmol/L), and a 14% reduction in apoB from baseline (–12.9 mg/dL) (all P < .01).

The effects were similar across age, continent, study duration, health status, intervention diet, intervention program, and study design subgroups.

There was no significant difference in triglyceride levels in patients in the omnivore versus plant-based diet groups.
 

Such diets could considerably reduce greenhouse gases

Senior author Dr. Frikke-Schmidt noted: “Recent systematic reviews have shown that if the populations of high-income countries shift to plant-based diets, this can reduce net emissions of greenhouse gases by between 35% to 49%.”

“Plant-based diets are key instruments for changing food production to more environmentally sustainable forms, while at the same time reducing the burden of cardiovascular disease” in an aging population, she said.

“We should be eating a varied, plant-rich diet, not too much, and quenching our thirst with water,” she concluded.

The study was funded by the Lundbeck Foundation, the Danish Heart Foundation, and the Leducq Foundation. The authors, editorialists, Ms. Parker, Dr. Cassidy, and Dr. Storey have reported no relevant financial relationships. Dr. Mellor has disclosed that he is a vegetarian.

PHOENIX – Post hoc analysis of the randomized TWILIGHT trial comparing ticagrelor alone with ticagrelor plus aspirin in high-risk patients after percutaneous coronary intervention (PCI) shows both regimens were similarly effective in preventing repeat revascularization after 1 year.

In TWILIGHT, the main findings of which were previously published in the New England Journal of Medicine, 7,119 high-risk PCI patients on standard dual antiplatelet therapy (DAPT) of ticagrelor plus aspirin for 3 months were randomized to continuation of DAPT or to ticagrelor plus placebo for 12 months.

University of Oklahoma

The new post hoc analysis included 6,759 patients and shows the rates of clinically driven revascularization were similar between the two groups: 7.1% and 6.6% for the ticagrelor monotherapy and ticagrelor-based DAPT groups, respectively (P = .363).

The findings were presented at the Society for Cardiovascular Angiography & Interventions annual scientific sessions. 

Three key findings come from the post hoc analysis, Usman Baber, MD, director of the cardiac catheterization lab and associate professor at the University of Oklahoma Health Sciences Center, Oklahoma City, who presented the findings, said in an interview.

“The first is that, over the 1-year follow-up of our trial, we found that a repeat revascularization event occurred in 6.7% of patients,” he said. “We found that a slight majority of these repeat revascularization events were due to events at the target lesion or target vessel; and we found that most of the repeat revascularization events actually occurred in patients without a concomitant acute coronary syndrome. In other words, these were essentially stable patients when they were getting their repeat revascularization.”

The second major finding was that these high-risk patients who had repeat revascularization were at three times greater risk for major adverse cardiac and cerebrovascular events (MACCE), based on a multivariable adjusted model, Dr. Baber said.

“And then third is that ticagrelor on its own as compared with ticagrelor plus aspirin was equally effective in preventing repeat revascularization events,” he said.
 

Repeat revascularization

The goal of the analysis was to focus on clinically driven repeat revascularization as an outcome, Dr. Baber said. The analysis also aimed to understand the association between repeat revascularization and subsequent risk.

Secondary endpoints included target lesion revascularization (TLR); target vessel revascularization (TVR); MACCE, including clinically driven revascularization; and net adverse clinical events (NACE), a composite of MACCE or Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding.

The outcomes of all those endpoints, except for NACE, were similar, Dr. Baber said. “Overall, ticagrelor monotherapy, as expected, reduced rates of bleeding as compared with ticagrelor plus aspirin,” he said. The rates of NACE were 12.2% versus 14.6%, respectively (P = .004). For BARC 2,3, or 5 bleeding, the rates were 3.4% versus 7.1% (P < .001).

The findings validated repeat revascularization as a meaningful endpoint, Dr. Baber said. “Certainly, we don’t elevate repeat revascularization as an endpoint to the same level as death or stroke, but certainly this analysis and some others prior to it highlight the fact that when these patients come back for repeat revascularization, even if they’re stable, they clearly are at elevated risk for future ischemic events,” he said.

One limitation of the analysis is that the data are from a clinical trial, “which renders the findings not as generalizable to the broader patients in a clinical practice,” he said. However, the TWILIGHT data are validated and adjusted for multiple risk factors.

“When patients come in and they have a repeat revascularization, should there be a consideration to placing them on more intensive antithrombotic therapy?” he asked. “Right now, if patients have a repeat revascularization event and they’re stable, guidelines and clinical practice usually calls for continuing clopidogrel, but again our study and others like it indicate these patients are at a higher thrombotic risk, so maybe there’s a rationale for at least a short course of a more potent antiplatelet agent in such patients.”

University of Washington

The post hoc findings confirm those of the primary TWILIGHT trial, Lorenzo Azzalini, MD, PhD, MSc, director of interventional cardiology research at the University of Washington Medical Center, Seattle, said in an interview.

“It’s not surprising to find no difference between the two therapies with regard to unplanned revascularization,” he said. “It’s considered that only stent thrombosis can only actually be mitigated by the drugs being investigated in the trial; all the other ischemic endpoints reflect more chronic ischemia—TLR or known TVR—upon which ticagrelor and aspirin do not play any role.”

However, he added, “I still think this study provides useful information to the community in a period of intense scrutiny on the relative benefits and merits of PCI versus CABG [coronary artery bypass graft], and this study confirms that shortening DAPT to 3 months and then continuing with just ticagrelor does not bring any penalty in terms of ischemic events or repeat revascularization.”

TWILIGHT enrolled high-risk patients, but not “very-high-risk” patients, Dr. Azzalini noted. The enrollment criteria excluded patients on chronic anticoagulation, who had a prior stroke or liver sclerosis, or were on dialysis.

“Future trials should focus more on very-high-risk patients because these are the patients that we deal with on a daily basis in our clinical practice and we need data to inform our decisions,” he said. “I’m not sure I could use the science contained in this study and extrapolate them to patients on dialysis because these patients really have a high risk of restenosis on follow-up.”

Dr. Baber disclosed relationships with Amgen and Abbott. Dr. Azzalini had no relevant disclosures.

However, he added, “I still think this study provides useful information to the community in a period of intense scrutiny on the relative benefits and merits of PCI versus CABG [coronary artery bypass graft], and this study confirms that shortening DAPT to 3 months and then continuing with just ticagrelor does not bring any penalty in terms of ischemic events or repeat revascularization.”

TWILIGHT enrolled high-risk patients, but not “very-high-risk” patients, Dr. Azzalini noted. The enrollment criteria excluded patients on chronic anticoagulation, who had a prior stroke or liver sclerosis, or were on dialysis.

“Future trials should focus more on very-high-risk patients because these are the patients that we deal with on a daily basis in our clinical practice and we need data to inform our decisions,” he said. “I’m not sure I could use the science contained in this study and extrapolate them to patients on dialysis because these patients really have a high risk of restenosis on follow-up.”

PHOENIX – Post hoc analysis of the randomized TWILIGHT trial comparing ticagrelor alone with ticagrelor plus aspirin in high-risk patients after percutaneous coronary intervention (PCI) shows both regimens were similarly effective in preventing repeat revascularization after 1 year.

In TWILIGHT, the main findings of which were previously published in the New England Journal of Medicine, 7,119 high-risk PCI patients on standard dual antiplatelet therapy (DAPT) of ticagrelor plus aspirin for 3 months were randomized to continuation of DAPT or to ticagrelor plus placebo for 12 months.

The new post hoc analysis included 6,759 patients and shows the rates of clinically driven revascularization were similar between the two groups: 7.1% and 6.6% for the ticagrelor monotherapy and ticagrelor-based DAPT groups, respectively (P = .363).

The findings were presented at the Society for Cardiovascular Angiography & Interventions annual scientific sessions. 

Three key findings come from the post hoc analysis, Usman Baber, MD, director of the cardiac catheterization lab and associate professor at the University of Oklahoma Health Sciences Center, Oklahoma City, who presented the findings, said in an interview.

“The first is that, over the 1-year follow-up of our trial, we found that a repeat revascularization event occurred in 6.7% of patients,” he said. “We found that a slight majority of these repeat revascularization events were due to events at the target lesion or target vessel; and we found that most of the repeat revascularization events actually occurred in patients without a concomitant acute coronary syndrome. In other words, these were essentially stable patients when they were getting their repeat revascularization.”

The second major finding was that these high-risk patients who had repeat revascularization were at three times greater risk for major adverse cardiac and cerebrovascular events (MACCE), based on a multivariable adjusted model, Dr. Baber said.

“And then third is that ticagrelor on its own as compared with ticagrelor plus aspirin was equally effective in preventing repeat revascularization events,” he said.
 

Repeat revascularization

The goal of the analysis was to focus on clinically driven repeat revascularization as an outcome, Dr. Baber said. The analysis also aimed to understand the association between repeat revascularization and subsequent risk.

Secondary endpoints included target lesion revascularization (TLR); target vessel revascularization (TVR); MACCE, including clinically driven revascularization; and net adverse clinical events (NACE), a composite of MACCE or Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding.

The outcomes of all those endpoints, except for NACE, were similar, Dr. Baber said. “Overall, ticagrelor monotherapy, as expected, reduced rates of bleeding as compared with ticagrelor plus aspirin,” he said. The rates of NACE were 12.2% versus 14.6%, respectively (P = .004). For BARC 2,3, or 5 bleeding, the rates were 3.4% versus 7.1% (P < .001).

The findings validated repeat revascularization as a meaningful endpoint, Dr. Baber said. “Certainly, we don’t elevate repeat revascularization as an endpoint to the same level as death or stroke, but certainly this analysis and some others prior to it highlight the fact that when these patients come back for repeat revascularization, even if they’re stable, they clearly are at elevated risk for future ischemic events,” he said.

One limitation of the analysis is that the data are from a clinical trial, “which renders the findings not as generalizable to the broader patients in a clinical practice,” he said. However, the TWILIGHT data are validated and adjusted for multiple risk factors.

“When patients come in and they have a repeat revascularization, should there be a consideration to placing them on more intensive antithrombotic therapy?” he asked. “Right now, if patients have a repeat revascularization event and they’re stable, guidelines and clinical practice usually calls for continuing clopidogrel, but again our study and others like it indicate these patients are at a higher thrombotic risk, so maybe there’s a rationale for at least a short course of a more potent antiplatelet agent in such patients.”

At the time that it was halted, a multicenter randomized trial was associating venoarterial extracorporeal membrane oxygenation (VA-ECMO) with an intriguing signal of benefit for patients in cardiogenic shock undergoing percutaneous intervention (PCI) for acute myocardial infarction.

Stopped early because of the pandemic, the EURO SHOCK trial has data on only 35 patients, but all-cause mortality at 30 days was nearly 30% lower in the VA-ECMO arm than in the standard-therapy arm, reported Manel Sabate, MD, PhD, chief of the interventional cardiology unit, Clinic University Hospital, Barcelona.

When patients were followed out to 12 months, the numerical survival advantage appeared to persist.

Yet, because of the early trial termination, “there really are no definite conclusions to be drawn from these results,” acknowledged Dr. Sabate, who noted that less than 10% of the planned enrollment had been reached. In addition, the survival benefit in the VA-ECMO arm was achieved at the cost of a higher rate of complications.

Despite the small numbers, results from the halted trial were presented as a late-breaker at the annual meeting of the European Association of Percutaneous Cardiovascular Interventions. They were also simultaneously published in EuroIntervention.

The interest is based on an important unmet need, said Dr. Sabate. Cardiogenic shock occurs in about 10% of acute MI patients. Of those that continue on to revascularization, the 30-day mortality can approach 50%.

Meanwhile, the potential of mechanical circulatory support to maintain perfusion during cardiogenic shock makes it one of the most attractive, if unproven, approaches for improving outcomes.
 

Major multicenter trial terminated

The EURO SHOCK trial had a planned enrollment of 428 patients when it was initiated; 15 centers in six European countries participated. Recruitment and the trial were brought to a halt by the COVID-19 pandemic.

When trial recruitment was stopped, 18 patients had been assigned to standard supportive care and 17 patients to VA-ECMO. The primary endpoint of the trial was all-cause mortality at 30 days. Mortality at 12 months along with bleeding complications, cerebrovascular events, and readmission for heart failure, were among secondary endpoints.

At 30 days, the mortality rate was 61.1% among patients randomized to standard care, versus 43.8% among patients randomized to VA ECMO (hazard ratio, 0.56; 95% confidence interval, 0.21-01.45; P = 0.22).

At 12 months, the numerical advantage of VA-ECMO persisted (81.5% vs. 51.8%) with a similar nonsignificant signal for potential benefit despite the small sample size (HR, 0.52; 95% CI, 0.21-1.26; P = 0.14).

There were also numerically lower rates of cardiovascular death, ischemic stroke, recurrent MI, and acute kidney injury among patients in the VA-ECMO group relative to those in the standard-care group, Dr. Sabate reported.

However, VA-ECMO was associated with more vascular complications (21.4% vs. 0%) and bleeding events (35.7% vs. 5.6%).

Furthermore, although quality of life data were limited, Dr. Sabate noted that about half of patients in the VA-ECMO group reported problems with mobility, self-care, or usual activities on the basis of the EQ-5D-3L questionnaire at 30 days. None of the patients in the standard-care group reported any such difficulties.

When standard care was compared with VA-ECMO, rates of readmission for heart failure over 12 months (8.0% vs. 6.9%) were not different.

To be enrolled in this study, patients being treated for MI had to be in cardiogenic shock for at least 30 minutes following primary PCI. The median time from onset of cardiogenic shock to VA-ECMO in the active treatment arm was 4.8 hours.
 

Patient enrollment was challenging

Even independent of the COVID-19 pandemic, enrolling patients proved to be difficult. The 35 patients enrolled represented about 10% of the 333 patients screened at the participating centers. Unwitnessed out-of-hospital cardiac arrest, cardiogenic shock from a cause other than MI, and recovery from cardiogenic shock after the PCI was performed were among reasons for the high rate of exclusions.

The difficulty of identifying and engaging appropriate candidates for VA-ECMO, along with a substantial crossover rate, should be among lessons for investigators planning the next trial, said Dr. Sabate, who pointed out that 5 of the 17 patients assigned to VA-ECMO were never treated due to complications or patient refusal.

“We cannot associate VA-ECMO with a favorable benefit-to-risk ratio on the basis of this study, but it sets the state for a larger randomized controlled trial to address this question,” Dr. Sabate said.

Davide Capodanno, MD, PhD, a professor of cardiology and interventional cardiologist at the University of Catania (Italy), agreed.

“It was a good decision to publish these results,” he said. Noting that there were challenges in conducting the trial unrelated to COVID-19, Dr. Capodanno acknowledged the promise of mechanical ventilatory support for a relatively common and life-threatening complication.

“This study must be read for the lessons it will provide for future trials,” he said.

Dr. Sabate reported he has no potential conflicts of interest. Dr. Capodanno reported financial relationships with Amgen, Daiichi Sankyo, and Sanofi.

WASHINGTON – Abrocitinib demonstrated an acceptable long-term safety profile in adolescents with moderate to severe atopic dermatitis (AD) in an integrated safety analysis of 635 adolescents and over 1,000 patient-years of exposure, Lawrence F. Eichenfield, MD, reported at the annual Revolutionizing Atopic Dermatitis conference.

In March 2023, the oral Janus kinase 1 (JAK1) inhibitor was approved by the Food and Drug Administration for treating adolescents aged 12-17 with refractory moderate to severe AD – an expanded indication from the approval in adults in 2022.

University of California, San Diego

The new analysis evaluated data from patients who participated in the phase 3 JADE clinical trials – MONO-1, MONO-2, TEEN, and REGIMEN – and were subsequently enrolled in the ongoing phase 3 extension trial JADE EXTEND. Compared with a previous post hoc analysis in which adolescent patients had approximately 1 year of exposure, this updated analysis includes a sizable portion of patients with more than 96 weeks of exposure.

“We’re starting to get good numbers of [adolescents] who’ve had about 2 years of exposure,” said Dr. Eichenfield, professor of dermatology and pediatrics and vice chair of the department of dermatology at the University of California, San Diego, during a late-breaking research session.

With a data cut for this analysis of September 2021, “we haven’t seen additive long-term [adverse] effects” with longer exposures, he said. In addition, “there were no unique safety concerns related to adolescents compared to the findings observed [in an] integrated safety analysis using the same data cut in which most patients were adults.”

(The analysis in adults covered 3,802 patients with over 5,000 patient-years of exposure, and was presented at the annual American Academy of Dermatology meeting in March 2023.)

Also presented in the late-breaking abstract session at RAD 2023 was a long-term safety study of upadacitinib (Rinvoq), the other JAK1 inhibitor approved for adolescents with AD – approved by the FDA for both adolescents and adults with moderate to severe AD in 2022. The new analysis captures exposure of up to 4 years and shows no “worsening or accumulation of events,” compared with 1-year data, reported Christopher G. Bunick, MD, PhD, of the department of dermatology and the program in translational biomedicine at Yale University, New Haven, Conn.
 

Abrocitinib in adolescents

For the safety analysis of abrocitinib (Cibinqo), data were pooled into two cohorts: A consistent-dose cohort of 490 adolescents who received the same dose (200 mg or 100 mg) during the entire duration of the qualifying JADE trials, and a variable-dose cohort of 145 adolescents who received different doses (200 mg or 100 mg) during the JADE REGIMEN qualifying trial.

Duration of exposure was 96 weeks or more in 37%-38% of the consistent-dose cohort and 68% of the variable-dose cohort.

In the consistent-dose cohort, adverse events occurred in 243 (84%) and 153 (76%) of patients receiving 200-mg doses and 100-mg doses, respectively. Incidence rates for severe adverse events were 5.87 per 100 patient-years at both doses, and rates for adverse events leading to study discontinuation were 6.96/100 patient-years at 200 mg and 5.13/100 patient-years at 100 mg.

“No meaningful dose-response relationship was observed for serious adverse events, or adverse events leading to discontinuation, or adverse events of special interest,” said Dr. Eichenfield, also chief of pediatric and adolescent dermatology at Rady Children’s Hospital, San Diego.

The IRs of adverse events of special interest were 1.84/100 patient-years and 1.28/100 patient-years for serious infection; 2.11/100 patient-years, and 1.62/100 patient-years for all herpes zoster infections; and 0.69/100 patient-years and 0.32/100 patient-years for opportunistic herpes zoster infections in the 200-mg and 100-mg arms, respectively.

“Other than herpes zoster, there were no opportunistic infections observed and no tuberculosis cases,” he said. “There was one nonfatal venous thromboembolism in an adolescent who had a very strong family history of [pulmonary embolism], one retinal detachment [with a concurrent diagnosis of cataracts and of left eyebrow folliculitis], and no events of nonmelanoma skin cancer or other malignancies, major adverse cardiovascular events, or deaths.” The thromboembolism case was reported in the previous post hoc analysis.

In the variable-dose cohort, data were similar, Dr. Eichenfield said. The IRs for severe adverse events, adverse events leading to study withdrawal, and adverse events of special interest were consistent with those in the other cohort. And similarly, there were no reports of tuberculosis or other opportunistic infections (excluding herpes zoster), and no reports of nonmelanoma skin cancer (NMSC) or other malignancies, major adverse cardiovascular events (MACE), or death. In this cohort, there were no venous thromboembolism (VTE) reports.

Upadacitinib in adolescents, adults

The new analysis looked at up to 4 years of upadacitinib treatment in almost 2,700 adolescents and adults– and over 6,200 patient-years – using integrated data from three ongoing pivotal phase 3 studies: Measure Up 1, Measure Up 2, and AD Up. (Of these patients, 539 were adolescents, Dr. Bunick said after the meeting.)

In the Measure Up studies, patients were randomized 1:1:1 to receive a 15-mg dose, a 30-mg dose, or placebo once daily. In AD Up, patients in each arm received concomitant topical corticosteroids. At week 16, patients receiving the drug continued their assigned treatment during the ongoing blinded extension period, and those receiving placebo were rerandomized to upadacitinib 15 mg or 30 mg.

The exposure-adjusted event rates for any adverse event leading to discontinuation were 4.1/100 patient-years and 4.7/100 patient-years in patients receiving 15 mg and 30 mg, respectively, and the rates of any serious adverse event were 6.5/100 patient-years and 7.5/100 patient-years, Dr. Bunick reported. Three deaths occurred in the 30-mg group; all deaths were related to COVID infection and occurred in adults with cardiovascular risk factors.

Incidence rates of adverse events of special interest were similar to those in a previous 1-year analysis. The rate of serious infections per 100 patient years, for instance, was 2.3 and 2.8 in the 15-mg and 30-mg groups, respectively, compared with 2.2 and 2.8 in the 1-year analysis.

The rate of opportunistic infections, including eczema herpeticum (and excluding TB and herpes zoster), saw a slight bump in the new analysis to 2.4/100 patient-years with the 30-mg dose. Other event rates, across both dosages and durations, were less than 0.1/100 patient-years for active TB; 0.3-0.4/100 patient-years for NMSC, and 0.1/100 patient-years or below for other malignancies, MACE, and VTE. Herpes zoster had the highest event rate in both the 1- and 4-year analyses of between 3.1/100 patient-years and 5.8/100 patient-years, Dr. Bunick reported.

The adverse event rates for adolescents and adults “show consistency and are very low,” Dr. Bunick said. At 4 years, no new safety risks were identified.
 

‘The more data ... the better’

Data on the safety of new medications in children and adolescents is always important, and with systemic JAK inhibitors in particular, “the more data we can accumulate in [younger] patients with AD ... the better,” said Robert Sidbury, MD, MPH, professor in the department of pediatrics at the University of Washington, Seattle, and chief of the division of dermatology at Seattle Children’s Hospital, who was asked to comment on the two studies.

Dermatologists have taken comfort in the fact that the “daunting” boxed warning on JAK inhibitors “was generated in a very different population than we generally propose to treat, certainly when talking about children and adolescents,” said Dr. Sidbury, who was not involved in either of the new safety analyses.

The JAK inhibitor boxed warning “reflects a study of tofacitinib – a different JAK inhibitor with arguably more risk of adverse effects – in adults over the age of 50 with rheumatoid arthritis and multiple risk factors for comorbidities included in the boxed warning,” he said.

“This allows dermatologists to reasonably conclude that the boxed warning – while critical to discuss and consider in every patient – is likely less concerning than might otherwise by implied.”

With more patient experience, “the more our assessment of risk, and of the ‘legitimacy’ of the boxed warning in our patient population, becomes evidence-based as opposed to extrapolation,” Dr. Sidbury said.

The two studies reported, he said, “detail an experience that is not adverse effect free –I have yet to find that medication – but is a reasonable profile considering the robust efficacy results they accompany.”

The abrocitinib safety analysis was sponsored by Pfizer. Regarding the study of upadacitinib, AbbVie contributed to the design of the safety analysis and participated in data collection. No honoria or payments were made to the authors, according to the study abstract. Dr. Eichenfield is a consultant/advisory board member for Pfizer and other companies, and has served on the speakers bureau/received honoria for Pfizer and other companies. Dr. Bunick is a consultant for AbbVie and other companies, and has served as an speaker/received honoraria or served as an investigator for several companies. Dr. Sidbury disclosed being a consultant/advisory board member for Lilly and Leo and serving on the speakers bureau/honoraria for Beiersdorf. All reported receiving grant/research support from various companies.

“We’re starting to get good numbers of [adolescents] who’ve had about 2 years of exposure,” said Dr. Eichenfield, professor of dermatology and pediatrics and vice chair of the department of dermatology at the University of California, San Diego, during a late-breaking research session.

With a data cut for this analysis of September 2021, “we haven’t seen additive long-term [adverse] effects” with longer exposures, he said. In addition, “there were no unique safety concerns related to adolescents compared to the findings observed [in an] integrated safety analysis using the same data cut in which most patients were adults.”

(The analysis in adults covered 3,802 patients with over 5,000 patient-years of exposure, and was presented at the annual American Academy of Dermatology meeting in March 2023.)

Also presented in the late-breaking abstract session at RAD 2023 was a long-term safety study of upadacitinib (Rinvoq), the other JAK1 inhibitor approved for adolescents with AD – approved by the FDA for both adolescents and adults with moderate to severe AD in 2022. The new analysis captures exposure of up to 4 years and shows no “worsening or accumulation of events,” compared with 1-year data, reported Christopher G. Bunick, MD, PhD, of the department of dermatology and the program in translational biomedicine at Yale University, New Haven, Conn.
 

Abrocitinib in adolescents

For the safety analysis of abrocitinib (Cibinqo), data were pooled into two cohorts: A consistent-dose cohort of 490 adolescents who received the same dose (200 mg or 100 mg) during the entire duration of the qualifying JADE trials, and a variable-dose cohort of 145 adolescents who received different doses (200 mg or 100 mg) during the JADE REGIMEN qualifying trial.

Duration of exposure was 96 weeks or more in 37%-38% of the consistent-dose cohort and 68% of the variable-dose cohort.

In the consistent-dose cohort, adverse events occurred in 243 (84%) and 153 (76%) of patients receiving 200-mg doses and 100-mg doses, respectively. Incidence rates for severe adverse events were 5.87 per 100 patient-years at both doses, and rates for adverse events leading to study discontinuation were 6.96/100 patient-years at 200 mg and 5.13/100 patient-years at 100 mg.

“No meaningful dose-response relationship was observed for serious adverse events, or adverse events leading to discontinuation, or adverse events of special interest,” said Dr. Eichenfield, also chief of pediatric and adolescent dermatology at Rady Children’s Hospital, San Diego.

The IRs of adverse events of special interest were 1.84/100 patient-years and 1.28/100 patient-years for serious infection; 2.11/100 patient-years, and 1.62/100 patient-years for all herpes zoster infections; and 0.69/100 patient-years and 0.32/100 patient-years for opportunistic herpes zoster infections in the 200-mg and 100-mg arms, respectively.

“Other than herpes zoster, there were no opportunistic infections observed and no tuberculosis cases,” he said. “There was one nonfatal venous thromboembolism in an adolescent who had a very strong family history of [pulmonary embolism], one retinal detachment [with a concurrent diagnosis of cataracts and of left eyebrow folliculitis], and no events of nonmelanoma skin cancer or other malignancies, major adverse cardiovascular events, or deaths.” The thromboembolism case was reported in the previous post hoc analysis.

In the variable-dose cohort, data were similar, Dr. Eichenfield said. The IRs for severe adverse events, adverse events leading to study withdrawal, and adverse events of special interest were consistent with those in the other cohort. And similarly, there were no reports of tuberculosis or other opportunistic infections (excluding herpes zoster), and no reports of nonmelanoma skin cancer (NMSC) or other malignancies, major adverse cardiovascular events (MACE), or death. In this cohort, there were no venous thromboembolism (VTE) reports.

Upadacitinib in adolescents, adults

The new analysis looked at up to 4 years of upadacitinib treatment in almost 2,700 adolescents and adults– and over 6,200 patient-years – using integrated data from three ongoing pivotal phase 3 studies: Measure Up 1, Measure Up 2, and AD Up. (Of these patients, 539 were adolescents, Dr. Bunick said after the meeting.)

In the Measure Up studies, patients were randomized 1:1:1 to receive a 15-mg dose, a 30-mg dose, or placebo once daily. In AD Up, patients in each arm received concomitant topical corticosteroids. At week 16, patients receiving the drug continued their assigned treatment during the ongoing blinded extension period, and those receiving placebo were rerandomized to upadacitinib 15 mg or 30 mg.

The exposure-adjusted event rates for any adverse event leading to discontinuation were 4.1/100 patient-years and 4.7/100 patient-years in patients receiving 15 mg and 30 mg, respectively, and the rates of any serious adverse event were 6.5/100 patient-years and 7.5/100 patient-years, Dr. Bunick reported. Three deaths occurred in the 30-mg group; all deaths were related to COVID infection and occurred in adults with cardiovascular risk factors.

Incidence rates of adverse events of special interest were similar to those in a previous 1-year analysis. The rate of serious infections per 100 patient years, for instance, was 2.3 and 2.8 in the 15-mg and 30-mg groups, respectively, compared with 2.2 and 2.8 in the 1-year analysis.

The rate of opportunistic infections, including eczema herpeticum (and excluding TB and herpes zoster), saw a slight bump in the new analysis to 2.4/100 patient-years with the 30-mg dose. Other event rates, across both dosages and durations, were less than 0.1/100 patient-years for active TB; 0.3-0.4/100 patient-years for NMSC, and 0.1/100 patient-years or below for other malignancies, MACE, and VTE. Herpes zoster had the highest event rate in both the 1- and 4-year analyses of between 3.1/100 patient-years and 5.8/100 patient-years, Dr. Bunick reported.

The adverse event rates for adolescents and adults “show consistency and are very low,” Dr. Bunick said. At 4 years, no new safety risks were identified.
 

‘The more data ... the better’

Data on the safety of new medications in children and adolescents is always important, and with systemic JAK inhibitors in particular, “the more data we can accumulate in [younger] patients with AD ... the better,” said Robert Sidbury, MD, MPH, professor in the department of pediatrics at the University of Washington, Seattle, and chief of the division of dermatology at Seattle Children’s Hospital, who was asked to comment on the two studies.

Dermatologists have taken comfort in the fact that the “daunting” boxed warning on JAK inhibitors “was generated in a very different population than we generally propose to treat, certainly when talking about children and adolescents,” said Dr. Sidbury, who was not involved in either of the new safety analyses.

The JAK inhibitor boxed warning “reflects a study of tofacitinib – a different JAK inhibitor with arguably more risk of adverse effects – in adults over the age of 50 with rheumatoid arthritis and multiple risk factors for comorbidities included in the boxed warning,” he said.

“This allows dermatologists to reasonably conclude that the boxed warning – while critical to discuss and consider in every patient – is likely less concerning than might otherwise by implied.”

With more patient experience, “the more our assessment of risk, and of the ‘legitimacy’ of the boxed warning in our patient population, becomes evidence-based as opposed to extrapolation,” Dr. Sidbury said.

The two studies reported, he said, “detail an experience that is not adverse effect free –I have yet to find that medication – but is a reasonable profile considering the robust efficacy results they accompany.”

The abrocitinib safety analysis was sponsored by Pfizer. Regarding the study of upadacitinib, AbbVie contributed to the design of the safety analysis and participated in data collection. No honoria or payments were made to the authors, according to the study abstract. Dr. Eichenfield is a consultant/advisory board member for Pfizer and other companies, and has served on the speakers bureau/received honoria for Pfizer and other companies. Dr. Bunick is a consultant for AbbVie and other companies, and has served as an speaker/received honoraria or served as an investigator for several companies. Dr. Sidbury disclosed being a consultant/advisory board member for Lilly and Leo and serving on the speakers bureau/honoraria for Beiersdorf.

WASHINGTON – Abrocitinib demonstrated an acceptable long-term safety profile in adolescents with moderate to severe atopic dermatitis (AD) in an integrated safety analysis of 635 adolescents and over 1,000 patient-years of exposure, Lawrence F. Eichenfield, MD, reported at the annual Revolutionizing Atopic Dermatitis conference.

In March 2023, the oral Janus kinase 1 (JAK1) inhibitor was approved by the Food and Drug Administration for treating adolescents aged 12-17 with refractory moderate to severe AD – an expanded indication from the approval in adults in 2022.

Women with Sjögren’s syndrome have pregnancy outcomes similar to those of the general population, according to the first study to prospectively track pregnancy outcomes among people with the autoimmune condition.

“Most early studies of pregnancy in rheumatic disease patients were retrospective and included only small numbers, making it difficult to know how generalizable the reported results were,” said Lisa Sammaritano, MD, a rheumatologist at Hospital for Special Surgery in New York, in an email interview with this news organization. She was not involved with the research.

Most of these previous studies suggested an increased risk of adverse outcomes, such as miscarriages, preterm deliveries, and small-for-gestational-age birth weight. But in addition to small patient numbers, retrospective studies “are subject to greater reporting bias, which may predispose patients with negative outcomes being more likely to be included because they were followed more closely,” Dr. Sammaritano said.

“This prospective study has several advantages over the earlier retrospective reports: The same data were collected in the same way for all the patients, the patients were recruited at similar time points, and – due to the multicenter nature of the cohort – numbers are larger than in prior studies. All these factors make the results stronger and more generalizable to the Sjögren’s patients we see in our practices,” she added.

In the study, published May 8 in The Lancet Rheumatology, first author Grégoire Martin de Frémont, MD, of the rheumatology service at Bicêtre Hospital, Paris-Saclay University and colleagues used the GR2 registry, an observational database of pregnancies of women with systemic autoimmune diseases managed at 76 participating centers in France, to identify pregnant women with primary Sjögren’s syndrome. To avoid bias, only women who entered the database before 18 weeks’ gestation were included. The final cohort included 106 pregnancies in 96 women with primary Sjögren’s syndrome and 420 control pregnancies that were matched from the general population.

Adverse pregnancy outcomes, including preterm delivery (< 37 weeks of gestation), intrauterine growth retardation, and low birth weight occurred in nine pregnancies (9%) in the Sjögren’s syndrome group and in 28 pregnancies in the control group (7%). Adverse pregnancy outcomes were not significantly associated with Sjögren’s syndrome (P = .52). Researchers found that there were more adverse pregnancy outcomes among women with Sjögren’s syndrome with antiphospholipid (aPL) antibodies. Negative outcomes also increased among those with anti-RNP antibodies, but this association was not statistically significant.

“The main message – based on strong data from a well-designed study – is that patients with Sjögren’s overall do as well as the general population in terms of standard adverse pregnancy outcomes. The rate of flare of Sjögren’s disease was relatively low during the second and third trimesters, also reassuring,” Dr. Sammaritano said. She noted that the association between adverse pregnancy outcomes and aPL antibodies was not unexpected, given that they are a known risk factor.

The study authors recommend that patients with Sjögren’s syndrome be screened for aPL and anti-RNP antibodies prior to conception because of the potential increased risk for complications and that patients with positive screens be closely monitored during their pregnancy.

Dr. Sammaritano noted that there are other health problems to keep in mind. “It is important to remember that Sjögren’s patients – more than any other rheumatic disease patients – have the additional risk for neonatal lupus and complete heart block in their infant, since about two-thirds of Sjögren’s patients are positive for anti-Ro/SSA antibody,” she said. “This is a distinct issue related to the presence of this antibody alone and not specifically related to the underlying diagnosis. In clinical practice, positive anti-Ro/SSA antibody is often the main reason for counseling, monitoring, and even recommending therapy (hydroxychloroquine) in these patients.”

The study received funding from Lupus France, the France Association of Scleroderma, and the Association Gougerot Sjögren, among others. Dr. Sammaritano reports no relevant financial relationships.

WASHINGTON – Patients with emphysema treated with one-way endobronchial values showed consistent improvement in lung function after 5 years compared with controls, based on data from 174 individuals.

One-way endobronchial valves demonstrated benefits for patients with severe emphysema over a 12-month period in the EMPROVE trial, according to Gerard J. Criner, MD, of Temple University, Philadelphia, and colleagues.

Five-year results from the EMPROVE study were presented in a poster session at the American Thoracic Society’s international conference.

The initial EMPROVE trial demonstrated safety and efficacy of the Spiration Valve System (SVS) over 12 months. However, data on the long-term benefits of one-way endobronchial values are limited, the researchers wrote.

The valve was designed for use in selected areas of the bronchial airways and features a flexible umbrella that allows air and mucus to clear from treated airways while blocking inspired air flow to areas of the lungs affected by disease, the researchers explained in the poster.

Dr. Criner and colleagues assessed 172 patients who were randomly assigned to treatment with a one-way valve system (113 patients) or a control group (59 patients).

Participants were evaluated at 1, 3, 6, and 12 months, then annually for 5 years.

The primary efficacy outcome was lung function, measured by forced expiratory volume per second (FEV₁). At five years, the FEV₁ values improved by 0.1098 liters in the treatment group (P < .001). Treated patients and controls experienced decreased FEV₁ at a rate of 0.0440 liters per year from baseline, a significant difference (P < .001). Assuming a steady rate of disease progression, “the treatment group gained approximately 2.5 years of FEV₁ improvement immediately following SVS treatment, which was maintained, compared to controls,” the researchers noted in their abstract.

Serious adverse events were assessed from 6 months to 5 years (352.7 patient-years) for treated patients and from 6 months to 2 years (72.9 patient-years) for controls.

Overall, 210 SAEs occurred in the treatment group and 35 occurred in controls, for rates of 0.60 and 0.48, respectively (P = .201). The most common SAEs in the treatment and control groups were COPD exacerbations, pneumothorax, and death.

The results suggest that the FEV₁ improvements seen in patients with severe emphysema after one-way endobronchial value placement compared with usual care are enduring after 5 years, with no significant changes in safety, the researchers concluded.

The original EMPROVE study was supported by Olympus Respiratory America, a part of Olympus Corporation and the developer of the Spiration Valve System. Results of the original study were published in the American Journal of Respiratory and Critical Care Medicine. Dr. Criner is associate editor of the American Journal of Respiratory and Critical Care Medicine. His participation complies with American Thoracic Society requirements for recusal from review and decisions for authored works.

One-way endobronchial valves demonstrated benefits for patients with severe emphysema over a 12-month period in the EMPROVE trial, according to Gerard J. Criner, MD, of Temple University, Philadelphia, and colleagues.

Five-year results from the EMPROVE study were presented in a poster session at the American Thoracic Society’s international conference.

The initial EMPROVE trial demonstrated safety and efficacy of the Spiration Valve System (SVS) over 12 months. However, data on the long-term benefits of one-way endobronchial values are limited, the researchers wrote.

The valve was designed for use in selected areas of the bronchial airways and features a flexible umbrella that allows air and mucus to clear from treated airways while blocking inspired air flow to areas of the lungs affected by disease, the researchers explained in the poster.

Dr. Criner and colleagues assessed 172 patients who were randomly assigned to treatment with a one-way valve system (113 patients) or a control group (59 patients).

Participants were evaluated at 1, 3, 6, and 12 months, then annually for 5 years.

The primary efficacy outcome was lung function, measured by forced expiratory volume per second (FEV₁). At five years, the FEV₁ values improved by 0.1098 liters in the treatment group (P < .001). Treated patients and controls experienced decreased FEV₁ at a rate of 0.0440 liters per year from baseline, a significant difference (P < .001). Assuming a steady rate of disease progression, “the treatment group gained approximately 2.5 years of FEV₁ improvement immediately following SVS treatment, which was maintained, compared to controls,” the researchers noted in their abstract.

Serious adverse events were assessed from 6 months to 5 years (352.7 patient-years) for treated patients and from 6 months to 2 years (72.9 patient-years) for controls.

Overall, 210 SAEs occurred in the treatment group and 35 occurred in controls, for rates of 0.60 and 0.48, respectively (P = .201). The most common SAEs in the treatment and control groups were COPD exacerbations, pneumothorax, and death.

The results suggest that the FEV₁ improvements seen in patients with severe emphysema after one-way endobronchial value placement compared with usual care are enduring after 5 years, with no significant changes in safety, the researchers concluded.

The original EMPROVE study was supported by Olympus Respiratory America, a part of Olympus Corporation and the developer of the Spiration Valve System. Results of the original study were published in the American Journal of Respiratory and Critical Care Medicine. Dr. Criner is associate editor of the American Journal of Respiratory and Critical Care Medicine. His participation complies with American Thoracic Society requirements for recusal from review and decisions for authored works.

Measurement error may be the culprit in underdiagnosing obstructive sleep apnea in Black patients, compared with White patients, based on data from nearly 2,000 individuals.

Data collected from ICU patients during the COVID-19 pandemic suggested that pulse oximetry devices used to measure oxygen saturation may be less accurate for patients with darker skin, according to Ali Azarbarzin, PhD, of Harvard Medical School, Boston.

“We wanted to examine the implications for obstructive sleep apnea,” which is often caused by a reduction in air flow, Dr. Azarbarzin said in an interview.

In a study presented at the American Thoracic Society’s international conference, Dr. Azarbarzin and colleagues examined data from 1,955 adults who were enrolled in the Multi-Ethnic Study of Atherosclerosis (MESA) Exam 5. The study participants underwent unattended 15-channel polysomnography that included a finger pulse oximeter. The mean age of the participants was 68.3 years, and 53.7% were women. A total of 12.1%, 23.7%, 27.7%, and 36.5% of the participants were Asian, Hispanic, Black, and White, respectively.

Apnea hypopnea index (AHI3P) was similar between Black and White patients, at approximately 19 events per hour. Black participants had higher wake SpO2, higher current smoking rates, and higher body mass index, compared with White participants, but these differences were not significant.

Severity of obstructive sleep apnea (OSA) was based on the hypoxic burden, which was defined as the total area under the respiratory curve. The total ventilatory burden was defined as the event-specific area under the ventilation signal and identified by amplitude changes in the nasal pressure signal. The researchers then calculated desaturation sensitivity (the primary outcome) as hypoxic burden divided by ventilatory burden.

In an unadjusted analysis, desaturation sensitivity was significantly lower in Black patients and Asian patients, compared with White patients (P < .001 and P < .02, respectively). After adjusting for age, sex, body mass index, and time spent in a supine position, desaturation sensitivity was lower only in Black patients, compared with White patients, and this difference persisted in both men and women.

The difference in desaturation sensitivity by race could be caused by differences in physiology or in measurement error, Dr. Azarbarzin told this news organization. If measurement error is the culprit, “we may be underestimating OSA severity in [Black people],” especially in Black women, he said.

However, more research is needed to understand the potential impact of both physiology and device accuracy on differences in oxygen saturation across ethnicities and to effectively identify and treat OSA in all patients, Dr. Azarbarzin said.

The MESA Study was supported by the National Institutes of Health and the National Institute on Aging. Data from MESA were obtained through support from the National Heart, Lung, and Blood Institute and the National Center for Advancing Translational Sciences. Dr. Azarbarzin disclosed funding from the National Institutes of Health, the American Health Association, and the American Academy of Sleep Medicine.

Amid growing criticism of health insurers’ onerous prior authorization practices, lawmakers in 30 states have introduced bills this year that aim to rein in insurer gatekeeping and improve patient care.

“This is something that goes on in every doctor’s office every day; the frustrations, the delays, and the use of office staff time are just unbelievable,” said Steven Orland, MD, a board-certified urologist and president of the Medical Society of New Jersey.

The bills, which cover private health plans and insurers that states regulate, may provide some relief for physicians as federal efforts to streamline prior authorization for some Medicare patients have lagged.

Last year, Congress failed to pass the Improving Seniors’ Timely Access to Care Act of 2021, despite 326 co-sponsors. The bill would have compelled insurers covering Medicare Advantage enrollees to speed up prior authorizations, make the process more transparent, and remove obstacles such as requiring fax machine submissions.

Last month, however, the Centers for Medicare & Medicaid Services issued a final rule that will improve some aspects of prior authorizations in Medicare Advantage insurance plans and ensure that enrollees have the same access to necessary care as traditional Medicare enrollees.

The insurance industry has long defended prior authorization requirements and opposed legislation that would limit them.

America’s Health Insurance Plans (AHIP) and the Blue Cross Blue Shield Association said in a 2019 letter to a congressional committee when the federal legislation was first introduced, “Prior authorizations enforce best practices and guidelines for care management and help physicians identify and avoid care techniques that would harm patient outcomes, such as designating prescriptions that could feed into an opioid addiction.” AHIP didn’t respond to repeated requests for comment.

But some major insurers now appear willing to compromise and voluntarily reduce the volume of prior authorizations they require. Days before the federal final rule was released, three major insurers – United HealthCare, Cigna, and Aetna CVS Health – announced they plan to drop some prior authorization requirements and automate processes.

United HealthCare said it will eliminate almost 20% of its prior authorizations for some nonurgent surgeries and procedures starting this summer. It also will create a national Gold Card program in 2024 for physicians who meet its eligibility requirements, which would eliminate prior authorization requirements for most procedures. Both initiatives will apply to commercial, Medicare Advantage, and Medicaid businesses, said the insurer in a statement.

However, United HealthCare also announced that in June it will start requiring prior authorization for diagnostic (not screening) gastrointestinal endoscopies for its nearly 27 million privately insured patients, citing data it says shows potentially harmful overuse of scopes. Physician groups have publicly criticized the move, saying it could delay lifesaving treatment, and have asked the insurer to reconsider.

Cigna and Aetna also have moved to pare back prior authorization processes. Scott Josephs, national medical officer for Cigna, told Healthcare Dive that Cigna has removed prior authorization reviews from nearly 500 services since 2020.

An Aetna spokesperson told Healthcare Dive that the CVS-owned payer has implemented a gold card program and rolled back prior authorization requirements on cataract surgeries, video EEGs, and home infusion for some drugs, according to Healthcare Dive.

Cigna has faced increased scrutiny from some state regulators since a ProPublica/The Capitol Forum article revealed in March that its doctors were denying claims without opening patients’ files, contrary to what insurance laws and regulations require in many states.

Over a period of 2 months last year, Cigna doctors denied over 300,000 requests for payments using this method, spending an average of 1.2 seconds on each case, the investigation found. In a written response, Cigna said the reporting by ProPublica and The Capitol Forum was “biased and incomplete.”
 

States aim to reduce prior authorization volume

The American Medical Association said it has been tracking nearly 90 prior authorization reform bills in 30 states. More than a dozen bills are still being considered in this legislative session, including in Arkansas, California, New Jersey, North Carolina, Maryland, and Washington, D.C.

“The groundswell of activity in the states reflects how big a problem this is,” said an AMA legislative expert. “The issue used to be ‘how can we automate and streamline processes’; now the issue is focused on reducing the volume of prior authorizations and the harm that can cause patients.”

The state bills use different strategies to reduce excessive prior authorization requirements. Maryland’s proposed bill, for example, would require just one prior authorization to stay on a prescription drug, if the insurer has previously approved the drug and the patient continues to successfully be treated by the drug.

Washington, D.C. and New Jersey have introduced comprehensive reform bills that include a “grace period” of 60 days, to ensure continuity of care when a patient switches health plans. They also would eliminate repeat authorizations for chronic and long-term conditions, set explicit timelines for insurers to respond to prior authorization requests and appeals, and require that practicing physicians review denials that are appealed.

Many state bills also would require insurers to be more transparent by posting information on their websites about which services and drugs require prior authorization and what their approval rates are for them, said AMA’s legislative expert.

“There’s a black hole of information that insurers have access to. We would really like to know how many prior authorization requests are denied, the time it takes to deny them, and the reasons for denial,” said Josh Bengal, JD, the director of government relations for the Medical Society of New Jersey.

The legislation in New Jersey and other states faces stiff opposition from the insurance lobby, especially state associations of health plans affiliated with AHIP. The California Association of Health Plans, for example, opposes a “gold card” bill (SB 598), introduced in February, that would allow a select group of high-performing doctors to skip prior authorizations for 1 year.

The CAHP states, “Californians deserve safe, high quality, high-value health care. Yet SB 598 will derail the progress we have made in our health care system by lowering the value and safety that Californians should expect from their health care providers,” according to a fact sheet.

The fact-sheet defines “low-value care” as medical services for which there is little to no benefit and poses potential physical or financial harm to patients, such as unnecessary CT scans or MRIs for uncomplicated conditions.

California is one of about a dozen states that have introduced gold card legislation this year. If enacted, they would join five states with gold card laws: West Virginia, Texas, Vermont, Michigan, and Louisiana.
 

How do gold cards work?

Physicians who achieve a high approval rate of prior authorizations from insurers for 1 year are eligible to be exempted from obtaining prior authorizations the following year.

The approval rate is at least 90% for a certain number of eligible health services, but the number of prior authorizations required to qualify can range from 5 to 30, depending on the state law.

Gold card legislation typically also gives the treating physician the right to have an appeal of a prior authorization denial by a physician peer of the same or similar specialty.

California’s bill would also apply to all covered health services, which is broader than what United HealthCare has proposed for its gold card exemption. The bill would also require a plan or insurer to annually monitor rates of prior authorization approval, modification, appeal, and denial, and to discontinue services, items, and supplies that are approved 95% of the time.

“These are important reforms that will help ensure that patients can receive the care they need, when they need it,” said CMA president Donaldo Hernandez, MD.

However, it’s not clear how many physicians will meet “gold card” status based on Texas’ recent experience with its own “gold card” law.

The Texas Department of Insurance estimated that only 3.3% of licensed physicians in the state have met “gold card” status since the bill became law in 2021, said Zeke Silva, MD, an interventional radiologist who serves on the Council of Legislation for the Texas Medical Association.

He noted that the legislation has had a limited effect for several reasons. Commercial health plans only make up only about 20% of all health plans in Texas. Also, the final regulations didn’t go into effect until last May and physicians are evaluated by health plans for “gold card” status every 6 months, said Dr. Silva.

In addition, physicians must have at least five prior authorizations approved for the same health service, which the law left up to the health plans to define, said Dr. Silva.

Now, the Texas Medical Association is lobbying for legislative improvements. “We want to reduce the number of eligible services that health plans require for prior authorizations and have more oversight of prior authorization denials by the Texas Department of Insurance and the Texas Medical Board,” said Dr. Silva.

He’s optimistic that if the bill becomes law, the number of physicians eligible for gold cards may increase.

Meanwhile, the AMA’s legislative expert, who declined to be identified because of organization policy, acknowledged the possibility that some prior authorization bills will die in state legislatures this year.

“We remain hopeful, but it’s an uphill battle. The state medical associations face a lot of opposition from health plans who don’t want to see these reforms become law.”
