Distance learning may cause convergence insufficiency
NEW ORLEANS – The increased use of digital screens for school during the COVID-19 pandemic may be causing convergence insufficiency in children, researchers say.
Although the long-term implications for current schoolchildren are not clear, convergence insufficiency sometimes persists for a lifetime, said Kammi Gunton, MD, interim chief of pediatric ophthalmology and strabismus at Wills Eye Hospital, Philadelphia.
“It’s important, if we use digital technology for education, that we are aware that it might contribute to increased eye symptoms in children,” Dr. Gunton told this news organization.
Dr. Gunton’s colleague, Jordan Hamburger, an MD candidate at Sidney Kimmel Medical College, Philadelphia, presented the finding at the American Academy of Ophthalmology 2021 Annual Meeting.
Convergence insufficiency is an impairment of binocularity. Symptoms include headaches while reading, words that seem to move around the page, blurriness, diplopia, and eye fatigue. It can be treated with exercise, prism glasses, or, rarely, surgery.
“We have some kids who improve with either time or maturity, then we have other patients who suffer from it for their entire lives,” Dr. Gunton said.
Previous research has linked the use of digital screens to convergence insufficiency, so when many schools shifted to distance learning for the pandemic, Dr. Gunton and her colleagues wanted to see whether it would have this effect on the students’ eyes.
They surveyed 110 healthy schoolchildren and adolescent students regarding eye symptoms before and after a day of virtual school. The mean age of the participants was 14 years (range, 10-17 years). The participants spent an average of 6.96 hours per day in virtual school. Forty-one percent also attended school in person part time. These students filled out the survey on days when they were in virtual school.
The participants answered questions on the Convergence Insufficiency Symptom Survey (CISS). The survey consists of 15 questions about eye complaints. On each question, the students rated symptoms from 0 to 4, with 4 indicating a severe symptom.
The average sum of the CISS scores rose from 5.17 before school to 9.82 after school, a statistically significant change (P < .001). Sixty-one percent of the participants reported an increase in convergence insufficiency symptoms.
Seventeen percent scored a total of at least 16, which is the threshold score considered suggestive of convergence insufficiency.
The researchers also found that, on average, the more hours each student spent in virtual school, the higher their CISS scores.
This makes sense, because reading requires convergence, Dr. Gunton said. The same problem might occur in traditional school if the students were looking at books all day instead of focusing on objects at various distances in their classrooms, such as the teacher or the whiteboard. “So, in the past, if you read a book, maybe you wouldn’t read for several hours, but now we’re asking children during virtual learning to stay on a device with the camera on,” she said.
Previous research has shown that people blink less when reading or using electronic devices, probably because of their increased concentration. This might explain symptoms such as burning and itching. Fifty-three percent of the students reported an increase in asthenopia symptoms.
The researchers would have liked to have compared the students in virtual school to a matched group of students in traditional school. However, almost all students were enrolled in virtual school when the study was conducted, making such a control difficult.
Although previous research has related virtual learning to myopia, as reported by this news organization, this study did not investigate myopia, and the researchers do not believe that convergence insufficiency causes myopia or vice versa.
Parents can help prevent convergence insufficiency during school by reminding their children to take breaks, Dr. Gunton said. She recommends the 20/20/20 rule: After 20 minutes of work that involves looking at objects nearby, students should take a 20-second break and look at something 20 feet away.
“I also think the take-home message is for parents to ask students if they’re having symptoms,” she said, “and if they hear complaints while kids are on the computers, to have them see an eye doctor and have an evaluation.”
Stephen Lipsky, MD, who wasn’t involved in the study, said he is seeing more cases of eye strain at Children’s Healthcare of Atlanta, where he is a consulting ophthalmologist.
“The study is very valuable in that it shines a light on the fact that these children do have symptoms, such as asthenopia or convergence insufficiency,” he told this news organization. “But I’m optimistic that with a return to more traditional learning, we will return the more traditional incidence of these problems.”
Dr. Gunton and Dr. Lipsky have disclosed no relevant financial relationships.

Empagliflozin a winner in challenging arena of stabilized acute HF
The sodium-glucose transporter 2 inhibitors, relative newcomers among first-line agents for chronic heart failure (HF), could well attain the same go-to status in patients hospitalized with acute HF if the EMPULSE trial has anything to say about it.
Of the study’s 530 such patients, those started on daily empagliflozin (Jardiance) soon after they were stabilized, compared with a control group, were less likely to die or be rehospitalized for HF over the next 3 months.
Also, “we saw an improvement in quality of life, we saw a greater reduction in body weight, and we didn’t see any safety concerns in this very vulnerable and sick patient population,” Adriaan A. Voors, MD, University Medical Center Groningen (the Netherlands), said when presenting the trial at the American Heart Association scientific sessions.
Patients assigned to empagliflozin had a 36% greater likelihood of showing a benefit as reflected in the treatment’s win ratio when opposed by placebo, an emerging way to express outcomes in cardiovascular clinical trials. The SGLT2 inhibitor’s win ratio for the primary endpoint was 1.36 (95% confidence interval, 1.09-1.68, P = .0054), Dr. Voors reported. The outcome consisted of death, number of HF events, time to first HF event, and 90-day change in quality of life scores.
There is reluctance in practice to start patients that early after decompensation on drugs used in chronic HF, Dr. Voors said in an interview. Empagliflozin in the trial was initiated in the stabilized setting an average of 3 days after hospital admission, he said. The trial should reassure physicians that the drug “is not only safe to start early in hospital, but it’s also beneficial to start early in hospital.”
EMPULSE, combined with support from other recent trials, “should be clinical practice changing, with early in-hospital initiation of SGLT2 inhibitors in patients hospitalized with HF being the expectation, along with clear recognition that delaying SGLT2 inhibitor initiation may expose patients to unnecessary harms and delays in improved health status,” Gregg C. Fonarow, MD, University of California Los Angeles Medical Center, told this news organization.
“For patients with HF, irrespective of ejection fraction, early in-hospital initiation of SGLT2 inhibitors – once stabilized and in the absence of contraindications – should be considered a new standard of care,” said Fonarow, who was not part of EMPULSE.
The trial also lends new weight to the strategy of “simultaneous or rapid-sequence initiation” of the so-called four pillars of guideline-directed medical therapy of HF with reduced ejection fraction in patients hospitalized with HFrEF, once they are stabilized, Dr. Fonarow said. The four-pronged approach, he noted, consists of sacubitril/valsartan (Entresto), a beta-blocker, a mineralocorticoid receptor antagonist (MRA), and an SGLT2 inhibitor.
Indeed, the new findings “fill an important gap and are clearly practice changing,” agreed Nancy K. Sweitzer, MD, PhD, University of Arizona Sarver Heart Center, Tucson, as an invited discussant following Dr. Voors’ presentation. “Few therapies have been shown to impact the course of those hospitalized with acute decompensated heart failure.”
Of note in the trial, Dr. Sweitzer continued, patients were started on empagliflozin regardless of any drug therapy they might already be on for chronic HF. “Because patients in the EMPULSE trial could be enrolled with a new diagnosis of heart failure, they were, by definition, not all on chronic guideline-directed heart failure therapy. Nevertheless, such patients benefited equally from the study intervention,” she said.
“This is crucial, as it tells us these drugs have immediate and important effects and should not be withheld while other drug classes are initiated and optimized.”
EMPULSE entered patients hospitalized for acute HF, which could be de novo or a decompensation of chronic HF, without regard to ejection fraction or whether they had diabetes, and who were clinically stable after at least one dose of loop diuretics. Their ejection fractions averaged 35% and exceeded 40% in about one-third of the total cohort.
At 90 days in the win ratio analysis, the 265 patients assigned to empagliflozin 10 mg once daily were the “winners”; that is, they were more likely to show a clinical benefit about 54% of the time in paired match-ups of patient outcomes, compared with about 40% for the 265 in the control group. The match-ups were a tie 6.4% of the time.
The empagliflozin group also benefited significantly for the endpoint of death from any cause or first HF event, with a hazard ratio of 0.65 (95% CI, 0.43-0.99; P = .042). They also were less likely to experience acute renal failure (7.7% vs. 12.1% for the control group) or serious adverse events (32.3% vs. 43.6%), Dr. Voors reported.
Tempting as it might be, the findings can’t necessarily be generalized to other SGLT2 inhibitors without an evidence base. But as Dr. Voors observed, several ongoing trials are exploring dapagliflozin (Farxiga) in a similar clinical setting.
They include DICTATE-AHF in patients with diabetes admitted with acute HF, and DAPA ACT HF-TIMI 68, which is entering patients stabilized during hospitalization with acute decompensated HFrEF. The trials are scheduled for completion in 2022 and 2023, respectively.
EMPULSE was supported by the Boehringer Ingelheim–Eli Lilly Diabetes Alliance. Dr. Voors disclosed research support and consulting for Amgen, AstraZeneca, Bayer, Boehringer Ingelheim, Cytokinetics, Merck, Myokardia, Novo Nordisk, Novartis, and Roche Diagnostics. Dr. Sweitzer disclosed honoraria from Acorda and Myokardia, and reported receiving research support from Novartis and Merck. Dr. Fonarow cited honoraria from Abbott, Amgen, Janssen, Medtronic, Bayer, Merck, AstraZeneca, Cytokinetics, and Novartis.

Endoscopic resection of esophageal cancer requires long-term post-op surveillance
LAS VEGAS – Although endoscopic resection of T1 esophageal adenocarcinoma (EAC) is associated with excellent overall survival, recurrence can occur years later, emphasizing the need for long-term surveillance, according to investigators.
Recurrence was about twice as common among patients lacking complete remission of intestinal metaplasia (CRIM) upon follow-up, reported lead author Kevin Song, MD, of the Mayo Clinic, Scottsdale, Ariz., and colleagues.
“Endoscopic resection of early-stage EAC has gained acceptance in recent years,” Dr. Song said during his presentation at the annual meeting of the American College of Gastroenterology. “While studies have demonstrated promising outcomes for short-term remission and recurrence, little is known about long-term recurrence and EAC-related mortality beyond 5 years.”
To address this knowledge gap, Dr. Song and colleagues reviewed data from 98 patients who had undergone endoscopic resection of T1 EAC at four tertiary academic centers with follow-up of at least 5 years. CRIM was defined by negative biopsies from the tubular esophagus and the gastroesophageal junction at one posttreatment surveillance endoscopy. Early recurrence was defined by a 2-year limit.
After a median follow-up of 8.76 years, 93 out of 98 patients (95%) experienced remission, while 82 patients (84%) demonstrated CRIM. Fourteen patients (14%) had recurrence of EAC, among whom eight (57%) had early recurrence at a median of 0.75 years (interquartile range, 0.43-0.80 years), while the other six (43%) had late recurrence at a median of 7.7 years (IQR, 5.20-8.77 years). Among the 93 patients entering remission, five (5.38%) had recurrence after 5 years.
CRIM was associated with a significantly lower rate of recurrence (11% vs. 46%; P = .01), generating an odds ratio of 6.55 (95% confidence interval, 1.71-26.71). Patients with CRIM also had later recurrence, at a median of 5.20 years, compared with 0.81 years for patients without CRIM. Moreover, the overall EAC-related mortality rate was 6.45%.
Dr. Song noted excellent overall survival and concluded his presentation by emphasizing the predictive value of CRIM and the need for long-term surveillance.
“CRIM should be considered the most significant endpoint for endotherapy of T1 EAC,” he said. “Surveillance is important even when early recurrence is not observed.”
Rishindra M. Reddy, MD, professor of thoracic surgery at the University of Michigan Health, Ann Arbor, agreed “100%” with Dr. Song and colleagues’ conclusion about the need for long-term surveillance.
“We struggle, in our patient population, to get people to do regular surveillance,” he said. “I think you have to have patients who have regular access to their gastroenterologist or surgeons and are willing to come in every 3 months to 6 months for surveillance endoscopies as well as CT scans.”
Dr. Reddy recommended that endoscopic resection of EAC be handled at high-volume centers.
“This really needs to be done in a multidisciplinary setting where you have both experienced endoscopists and thoracic surgeons and/or surgical oncologists who do esophagectomies to make these decisions about optimal treatment,” he said, “as well as pathologists who are more experienced in what to look for in terms of depth or lateral margins.”
The present work is a “great first study,” Dr. Reddy said. He suggested that larger real-world trials are needed to confirm findings and compare outcomes between tumor subtypes.
“I think for T1a tumors, there’s a good consensus on endoscopic mucosal resection,” he said. “I think T1b is an area where we would suggest more often doing surgery… and there’s even some nuance at a T1a level about the depth. It would be helpful to understand the risks of recurrence after [resecting] different levels of T1 tumors.”
The investigators disclosed relationships with CDX, Interpace, Lucid, and others. Dr. Reddy disclosed no relevant conflicts of interest.
LAS VEGAS – Although endoscopic resection of T1 esophageal adenocarcinoma (EAC) is associated with excellent overall survival, recurrence can occur years later, emphasizing the need for long-term surveillance, according to investigators.
Recurrence was about twice as common among patients lacking complete remission of intestinal metaplasia (CRIM) upon follow-up, reported lead author Kevin Song, MD, of the Mayo Clinic, Scottsdale, Ariz., and colleagues.
“Endoscopic resection of early-stage EAC has gained acceptance in recent years,” Dr. Song said during his presentation at the annual meeting of the American College of Gastroenterology. “While studies have demonstrated promising outcomes for short-term remission and recurrence, little is known about long-term recurrence and EAC-related mortality beyond 5 years.”
To address this knowledge gap, Dr. Song and colleagues reviewed data from 98 patients who had undergone endoscopic resection of T1 EAC at four tertiary academic centers with follow-up of at least 5 years. CRIM was defined by negative biopsies from the tubular esophagus and the gastroesophageal junction at one posttreatment surveillance endoscopy. Early recurrence was defined by a 2-year limit.
After a median follow-up of 8.76 years, 93 out of 98 patients (95%) experienced remission, while 82 patients (84%) demonstrated CRIM. Fourteen patients (14%) had recurrence of EAC, among whom eight (57%) had early recurrence at a median of 0.75 years (interquartile range, 0.43-0.80 years), while the other six (43%) had late recurrence at a median of 7.7 years (IQR, 5.20-8.77 years). Among the 93 patients entering remission, five (5.38%) had recurrence after 5 years.
CRIM was associated with a significantly lower rate of recurrence (11% vs. 46%; P = .01), generating an odds ratio of 6.55 (95% confidence interval, 1.71-26.71). Patients with CRIM also had later recurrence, at a median of 5.20 years, compared with 0.81 years for patients without CRIM. Moreover, the overall EAC-related mortality rate was 6.45%.
Dr. Song noted excellent overall survival and concluded his presentation by emphasizing the predictive value of CRIM and the need for long-term surveillance.

Prior biologic exposure no barrier for ozanimod in ulcerative colitis
The oral sphingosine-1-phosphate receptor modulator ozanimod is significantly more effective than placebo for treating patients with moderate to severe ulcerative colitis, regardless of prior biologic exposure, based on results of the phase 3 True North trial.
Although improvements were seen across all patients, those who had previously used biologics took slightly longer to respond to treatment, which suggests that any initial improvements with ozanimod warrant continuation of therapy to achieve full effect, reported to lead author Bruce E. Sands, MD, of Icahn School of Medicine at Mount Sinai, New York, and colleagues.
“[Ulcerative colitis] patients previously treated with a biologic agent may be less likely to respond to another advanced treatment,” Dr. Sands said during a presentation at the annual meeting of the American College of Gastroenterology.
Dr. Sands and colleagues evaluated this possibility in the True North trial, which previously demonstrated superior efficacy and safety of ozanimod over placebo through 1 year.
The present dataset included a double-blinded cohort of 639 patients (cohort 1), among whom 213 took placebo and 426 took ozanimod, and an open-label cohort of 353 patients who took ozanimod (cohort 2). Outcomes included clinical remission, clinical response, endoscopic improvement, and mucosal healing.
During induction (through week 10), biologic-naive patients in both cohorts generally responded better to ozanimod than those who had received at least one prior biologic. Patients who had received two or more biologics showed less improvement than those who had received only one prior biologic.
For example, in cohort 1, 53% of biologic-naive patients in the ozanimod group achieved a clinical response, compared with 50% of patients who had received one prior biologic, and just 27.2% of patients who had received two or more biologics.
With maintenance therapy, however, these differences faded. Among participants continuing ozanimod through week 52, 60.7% of biologic-naive patients achieved a clinical response, compared with 60.5% of those who had taken one prior biologic, and 55.3% of patients who had taken two or more prior biologics.
“Ozanimod treatment for up to 52 weeks in patients with moderate to severe ulcerative colitis improved clinical symptoms, mucosal ulcerations, and reduced cellular inflammation in both biologic-exposed and biologic-naive patients,” Dr. Sands concluded. “Greater efficacy was observed in biologic-naive patients, followed by patients with prior exposure to one biologic, at induction; however, all groups had benefits at end of maintenance. Patients with prior biologic use may require additional time to respond to treatment.”
Bradley Morganstern, MD, codirector of the IBD Center at Stony Brook (N.Y.) Medicine, called the study “a really important analysis” that addresses a common clinical decision.
“We often see a lower response rate among patients previously on biologics, but we have very limited data to guide us on how to choose a second-line agent,” Dr. Morganstern said during an interview.
He said the current findings encourage use of ozanimod for patients who didn’t respond to other biologics.
“The takeaway is that just because someone didn’t respond to a biologic in the past doesn’t mean they won’t respond to this,” Dr. Morganstern said. “They actually have a very good chance of responding – similar to the rest of the population that was never on medication.”
He went on to explain that exact treatment sequencing remains unclear, although ozanimod is a strong candidate in the second line.
“We can’t 100% say where it [ozanimod] fits in,” Dr. Morganstern said, “but we should certainly place it high up in the algorithm for patients who have failed a biologic. This should strongly be considered as a second-line agent.”
Dr. Morganstern said that he looks forward to long-term findings from True North beyond 1 year, “in terms of maintaining response,” and additional safety data.
The study was funded supported by Bristol-Myers Squibb. The investigators disclosed additional affiliations with AstraZeneca, AbbVie, Amgen, and others. Dr. Morganstern has previously spoken for Bristol-Myers Squibb.

ADVOCATE: Avacopan shows renal benefits in ANCA vasculitis
Treatment of antineutrophil cytoplasmic autoantibody (ANCA)–associated vasculitis and renal disease with the oral C5a receptor inhibitor avacopan (Tavneos, ChemoCentryx) provides significant recovery of kidney function, compared with prednisone, particularly in patients with severe kidney disease, novel research indicates.
The new analysis underscores that “the real value of avacopan is that we can now expect to get our patients steroid free,” said first author David R.W. Jayne, MD, a professor of clinical autoimmunity at the University of Cambridge (England), when presenting the findings at the American Society of Nephrology’s Kidney Week 2021.
“Whether or not we’re brave enough to initiate treatment without steroids, I think that will perhaps come with some patient experience,” he added.
The findings are from a subanalysis of renal effects in the phase 3 ADVOCATE trial, which was published in February 2021 in the New England Journal of Medicine and included 330 patients with ANCA-associated vasculitis.
The trial in large part led to the U.S. approval of avacopan by the Food and Drug Administration in October as an adjunctive treatment for adults with severe active ANCA-associated vasculitis in combination with standard therapy including glucocorticoids.
The approval was greeted with enthusiasm as suggesting a much-needed option to help reduce, or even potentially eliminate, the need for glucocorticoids and their side effects. Other agents included in treatment regimens for ANCA-associated vasculitis include cyclophosphamide and rituximab.
Dr. Jayne emphasized that, before avacopan, treatment options had been limited.
“There is nothing else new in the clinic apart from rituximab, which we have now been using for almost 20 years,” he said in an interview. “Avacopan is new, the mode of action is different from any drugs in use at the moment, and the speed of action is very quick.”
The need to more closely investigate the trial’s renal outcomes in this new analysis was important because the high mortality rates in ANCA-associated vasculitis – a rare systemic autoimmune disease causing overactivation of complement resulting in inflammation of small blood vessels – is largely driven by those with MPO and PR3 autoantibody renal vasculitis, Dr. Jayne explained.
Commenting on the study, J. Charles Jennette, MD, a professor of pathology and laboratory medicine and professor of medicine at the University of North Carolina at Chapel Hill, said the new findings on renal outcomes, such as proteinuria, may offer key insights on avacopan’s efficacy.
“To me, the most impressive outcome of the ADVOCATE Phase 3 trial was the more rapid reduction in hematuria and proteinuria with avacopan compared to conventional prednisone therapy,” he said in an interview.
Recovery of eGFR with avacopan best in those with severe renal disease
In the trial, patients with ANCA-associated vasculitis were randomized 1:1 to treatment with oral avacopan 30 mg twice daily or oral prednisone on a tapering schedule.
All patients also received background immunosuppression – about two-thirds received rituximab and a third received cyclophosphamide – followed by azathioprine.
The main study results showed similar rates of remission in both groups at week 26 and a superior remission rate with avacopan, in terms of sustained remission, at week 52 (65.7% vs. 54.9%; P < .001).
Approximately 80% of patients in the trial had renal involvement of ANCA vasculitis, the focus of the new analysis, and they had a baseline mean estimated glomerular filtration rate (eGFR) of 45 mL/min per 1.73 m2.
Among those with renal involvement, patients treated with avacopan had a significantly greater eGFR recovery, compared with the prednisone group at week 26 (P = .046) and week 52 (P < .029).
The strongest improvements were observed among patients with moderate to severe kidney damage, who had a mean eGFR of 21 mL/min per 1.73 m2 at baseline. Among those patients, the mean increase in eGFR was 13.7 mL/min per 1.73 m2 in the avacopan-treated group (n = 52) versus 8.2 mL/min per 1.73 m2 in the prednisone group (n = 48; P < .01) by week 52.
Improvements in urinary albumin:creatinine ratios (UACR) of as much as 40% were also observed in the avacopan group within the first 4 weeks of treatment, while no changes were observed in the same period in the prednisone group.
In other findings, the study also showed more rapid declines in proteinuria within 4 weeks in the avacopan group, and fewer patients had hematuria and there were greater reductions in MCP-1 in avacopan-treated patients at week 52, Dr. Jayne reported.
In terms of safety, there were no differences between the groups, with trends of fewer deaths and severe adverse events in the avacopan group.
“We found that the improved recovery of eGFR with avacopan was accentuated among those with more severe renal disease,” Dr. Jayne said.
He noted that, while the study’s aim was for the avacopan group to be steroid free, the patients received brief, reduced doses of about a third of the normal oral steroid dose early in the trial. However, using a Glucocorticoid Toxicity Index, the authors found those in the avacopan group did have fewer glucocorticoid-related adverse events.
Future issues to be examined include what happens when avacopan is discontinued and whether there will be a high relapse rate, Dr. Jayne noted.
Overall, however, “we anticipate that with longer-term follow-up, this better eGFR recovery will have a [favorable] effect on kidney failure and potentially mortality risk in these patients,” he concluded.
Targeted therapy is good for patients and doctors
Expanding upon his comments regarding the new drug, Dr. Jennette said it implies “that the C5a receptor inhibitor was targeting an event that blocks injury more quickly and effectively than prednisone.”
“This may be because prednisone has more complex pharmacodynamics and less targeted effects than a C5a receptor inhibitor,” he said.
Overall, the findings bode well for a potentially beneficial therapy, he added. “We have entered a new era of more targeted therapies, for example, targeted B-cell therapy using an anti-CD20 antibody, and targeted complement-mediated injury therapy using C5a receptor inhibitor.”
“The validation of this targeted therapy to block complement-mediated autoimmune inflammatory injury is another advance toward targeted precision therapy versus empirical therapy. This will be good for the doctors and good for the patients,” Dr. Jennette concluded.
The study was funded by ChemoCentryx. Dr. Jayne has reported receiving grants and/or consulting for AstraZeneca, ChemoCentryx, GlaxoSmithKline, MiroBio, Vifor, and Roche/Genentech. Dr. Jennette has received funding from ChemoCentryx for preclinical validation studies of avacopan in a mouse model of ANCA glomerulonephritis.

“The validation of this targeted therapy to block complement-mediated autoimmune inflammatory injury is another advance toward targeted precision therapy versus empirical therapy. This will be good for the doctors and good for the patients,” Dr. Jennette concluded.
The study was funded by ChemoCentryx. Dr. Jayne has reported receiving grants and/or consulting for AstraZeneca, ChemoCentryx, GlaxoSmithKline, MiroBio, Vifor, and Roche/Genentech. Dr. Jennette has received funding from ChemoCentryx for preclinical validation studies of avacopan in a mouse model of ANCA glomerulonephritis.

Treatment of antineutrophil cytoplasmic autoantibody (ANCA)–associated vasculitis and renal disease with the oral C5a receptor inhibitor avacopan (Tavneos, ChemoCentryx) provides significant recovery of kidney function, compared with prednisone, particularly in patients with severe kidney disease, novel research indicates.
The new analysis underscores that “the real value of avacopan is that we can now expect to get our patients steroid free,” said first author David R.W. Jayne, MD, a professor of clinical autoimmunity at the University of Cambridge (England), when presenting the findings at the American Society of Nephrology’s Kidney Week 2021.
“Whether or not we’re brave enough to initiate treatment without steroids, I think that will perhaps come with some patient experience,” he added.
The findings are from a subanalysis of renal effects in the phase 3 ADVOCATE trial, which was published in February 2021 in the New England Journal of Medicine and included 330 patients with ANCA-associated vasculitis.
The trial in large part led to the U.S. approval of avacopan by the Food and Drug Administration in October as an adjunctive treatment for adults with severe active ANCA-associated vasculitis in combination with standard therapy including glucocorticoids.
The approval was greeted with enthusiasm as suggesting a much-needed option to help reduce, or even potentially eliminate, the need for glucocorticoids and their side effects. Other agents included in treatment regimens for ANCA-associated vasculitis include cyclophosphamide and rituximab.
Dr. Jayne emphasized that, before avacopan, treatment options had been limited.
“There is nothing else new in the clinic apart from rituximab, which we have now been using for almost 20 years,” he said in an interview. “Avacopan is new, the mode of action is different from any drugs in use at the moment, and the speed of action is very quick.”
The need to more closely investigate the trial’s renal outcomes in this new analysis was important because the high mortality rates in ANCA-associated vasculitis – a rare systemic autoimmune disease causing overactivation of complement resulting in inflammation of small blood vessels – is largely driven by those with MPO and PR3 autoantibody renal vasculitis, Dr. Jayne explained.
Commenting on the study, J. Charles Jennette, MD, a professor of pathology and laboratory medicine and professor of medicine at the University of North Carolina at Chapel Hill, said the new findings on renal outcomes, such as proteinuria, may offer key insights on avacopan’s efficacy.
“To me, the most impressive outcome of the ADVOCATE Phase 3 trial was the more rapid reduction in hematuria and proteinuria with avacopan compared to conventional prednisone therapy,” he said in an interview.
Recovery of eGFR with avacopan best in those with severe renal disease
In the trial, patients with ANCA-associated vasculitis were randomized 1:1 to treatment with oral avacopan 30 mg twice daily or oral prednisone on a tapering schedule.
All patients also received background immunosuppression – about two-thirds received rituximab and a third received cyclophosphamide – followed by azathioprine.
The main study results showed similar rates of remission in both groups at week 26 and a superior remission rate with avacopan, in terms of sustained remission, at week 52 (65.7% vs. 54.9%; P < .001).
Approximately 80% of patients in the trial had renal involvement of ANCA vasculitis, the focus of the new analysis, and they had a baseline mean estimated glomerular filtration rate (eGFR) of 45 mL/min per 1.73 m2.
Among those with renal involvement, patients treated with avacopan had a significantly greater eGFR recovery, compared with the prednisone group at week 26 (P = .046) and week 52 (P < .029).
The strongest improvements were observed among patients with moderate to severe kidney damage, who had a mean eGFR of 21 mL/min per 1.73 m2 at baseline. Among those patients, the mean increase in eGFR was 13.7 mL/min per 1.73 m2 in the avacopan-treated group (n = 52) versus 8.2 mL/min per 1.73 m2 in the prednisone group (n = 48; P < .01) by week 52.
Improvements in urinary albumin:creatinine ratios (UACR) of as much as 40% were also observed in the avacopan group within the first 4 weeks of treatment, while no changes were observed in the same period in the prednisone group.
In other findings, the study also showed more rapid declines in proteinuria within 4 weeks in the avacopan group, and fewer patients had hematuria and there were greater reductions in MCP-1 in avacopan-treated patients at week 52, Dr. Jayne reported.
In terms of safety, there were no differences between the groups, with trends of fewer deaths and severe adverse events in the avacopan group.
“We found that the improved recovery of eGFR with avacopan was accentuated among those with more severe renal disease,” Dr. Jayne said.
He noted that, while the study’s aim was for the avacopan group to be steroid free, the patients received brief, reduced doses of about a third of the normal oral steroid dose early in the trial. However, using a Glucocorticoid Toxicity Index, the authors found those in the avacopan group did have fewer glucocorticoid-related adverse events.
Future issues to be examined include what happens when avacopan is discontinued and whether there will be a high relapse rate, Dr. Jayne noted.
Overall, however, “we anticipate that with longer-term follow-up, this better eGFR recovery will have a [favorable] effect on kidney failure and potentially mortality risk in these patients,” he concluded.
Targeted therapy is good for patients and doctors
Expanding upon his comments regarding the new drug, Dr. Jennette said it implies “that the C5a receptor inhibitor was targeting an event that blocks injury more quickly and effectively than prednisone.”
“This may be because prednisone has more complex pharmacodynamics and less targeted effects than a C5a receptor inhibitor,” he said.
Overall, the findings bode well for a potentially beneficial therapy, he added. “We have entered a new era of more targeted therapies, for example, targeted B-cell therapy using an anti-CD20 antibody, and targeted complement-mediated injury therapy using C5a receptor inhibitor.”
“The validation of this targeted therapy to block complement-mediated autoimmune inflammatory injury is another advance toward targeted precision therapy versus empirical therapy. This will be good for the doctors and good for the patients,” Dr. Jennette concluded.

Long-term glucocorticoids in RA linked to increased cardiovascular risk
Each month of glucocorticoid use in middle-aged patients with rheumatoid arthritis increases their odds of a major adverse cardiac event by 14%, independent of their baseline cardiovascular risk, according to a Veterans Administration study presented at the virtual annual meeting of the American College of Rheumatology. A similar study of Medicare and insurance claims data also presented at the meeting similarly found a dose-dependent increase in cardiovascular risk with long-term glucocorticoid use among patients with RA.
Up to half of patients with RA use long-term glucocorticoids, Beth Wallace, MD, an assistant professor of internal medicine at the University of Michigan, Ann Arbor, and a staff rheumatologist at the VA Ann Arbor Healthcare Center, told attendees in her presentation.
“Despite previous work suggesting they increase major [adverse] cardiovascular events, or MACE, in a dose-dependent way, prior work suggests long-term glucocorticoid use is common among RA patients with traditional basic risk factors like hyperlipidemia, diabetes, hypertension, and smoking,” Dr. Wallace said. “But we know little about the incremental effects of ongoing glucocorticoid use on MACE risk in RA, particularly as traditional predisposing comorbidities might confound its assessment.”
Christie Bartels, MD, associate professor and division head of rheumatology at the University of Wisconsin, Madison, said in an interview that these findings indicate a need to consider the risks of long-term glucocorticoid use for RA.
“The clinical implications of these studies include informed consent when using steroids in patients and when advocating for steroid-sparing therapy,” said Dr. Bartels, who was not involved in either study. ”We have never had more options for steroid-sparing medications in rheumatoid arthritis than we have right now, making it a critical time to reduce glucocorticoid use whenever possible. For short-term function and pain relief, or in some cases with many contraindications, there is still a role for glucocorticoid use, but these data show that no amount of longer-term glucocorticoid use is without risk.”
VA study details
The retrospective cohort study relied on VA administrative data for 26,239 patients with RA who had at least one rheumatology visit during 2013-2017. Only adults aged 40-90 were included (85% men), and none had other rheumatologic conditions, a previous MACE, or congestive heart failure in the preceding 5 years.
The researchers used pharmacy dispensing data to determine exposure to glucocorticoids, based on the number of days’ supply per 6 months and claims data to identify the primary outcome of MACE, defined as acute myocardial infarction, stroke, transient ischemic attack, cardiac arrest, or coronary revascularization, in the following 6 months. After a first MACE, a patient was removed from subsequent analysis so that only a participant’s initial event was considered.
The researchers adjusted their analysis for demographics, health care utilization, long-term glucocorticoid use (over 90 days), use of methotrexate or biologics, and baseline cardiac risk based on the Veterans Affairs Risk Score for Cardiovascular Disease (VARS-CVD). The VARS-CVD uses age, sex, race, tobacco use, systolic blood pressure, cholesterol, diabetes diagnosis, and use of antihypertensives to estimate the risk of a MACE in the next 5 years. A 5-year risk of less than 3% was considered low, 3%-9% medium, and above 9% high.
The population’s median 5-year MACE risk based on VARS-CVD was 5.7%, with nearly a quarter of participants (23%) having a high risk. During the first year of follow-up, 23% of patients overall, including 24% of those with high risk, received at least 90 days of glucocorticoids. An incident MACE occurred in 3.2% of overall patients and in 4.9% of high-risk patients. Median time until an incident MACE was 25 months.
After adjusting for confounders, the researchers calculated that each additional 30 days of glucocorticoid use per 6-month period was linked to a 14% increase in odds of a MACE in the subsequent 6-month period (odds ratio, 1.14). This finding remained independent of baseline cardiovascular risk, previous long-term exposure to glucocorticoids, baseline office visits, methotrexate or biologic use, and baseline Elixhauser Cormobidity Index (except rheumatoid arthritis, diabetes, hypertension, and congestive heart failure).
Dr. Wallace noted that the observational study could still include residual confounding because of factors such as rheumatic disease activity, glucocorticoid dose, and care outside the VA. They also did not distinguish between existing and incident RA and were missing some VARS-CVD data, and they did not adjust for hydroxychloroquine use, which can reduce cardiovascular risk.
Details of Medicare and private insurance claims study
In the second study, Brian Coburn, MD, a fourth-year internal medicine resident at the University of Pennsylvania, Philadelphia, presented findings on long-term glucocorticoid use and cardiovascular outcomes in patients with RA based on 2006-2015 claims data from Medicare and the Optum Clinformatics Data Mart. That study similarly found a dose-dependent increase in cardiovascular risk with increasing dosage of long-term glucocorticoids.
All the patients in the two databases had an RA diagnosis and remained on disease-modifying antirheumatic drugs (DMARDs) for at least 180 days without adding a new DMARD or stopping therapy for more than 90 days. Patients were not included if they had a history of myocardial infarction, stroke, coronary artery bypass grafting, or percutaneous coronary intervention.
Using the 180 days before and after starting DMARDs as baseline, the researchers assessed average dose of glucocorticoids during the last 90 days of the baseline period. Participants included 135,583 patients with Medicare, contributing 158,839 years at risk, and 39,272 patients in the Optum database, contributing 36,876 years at risk. The researchers then assessed composite cardiovascular events as a combination of strokes and myocardial infarctions.
A total of 2,067 cardiovascular events occurred among the Medicare patients, for a incidence of 1.3 events per 100 people per year, and 313 cardiovascular events occurred among Optum patients, for an incidence of 0.8 events per 100 people per year.
Over 1 year, a predicted 1.1% of Medicare patients not taking glucocorticoids would experience a stroke or heart attack, compared with 1.4% of those taking up to 5 mg/day of glucocorticoids, 1.7% of those taking 5-10 mg/day glucocorticoids, and 1.9% of those taking more than 10 mg/day glucocorticoids. The number needed to harm was 400 people for up to 5 mg/day, 192 people for 5-10 mg/day, and 137 people for more than 10 mg/day.
Among Optum patients, 0.7% not taking glucocorticoids would experience a stroke or heart attack over 1 year, compared with 0.9% of those taking up to 5 mg/day and 0.8% of those taking either 5-10 mg/day or more than 10 mg/day. The number needed to harm was 714 people for up to 5 mg/day of glucocorticoids, 5,000 people for 5-10 mg/day, and 1,667 for over 10 mg/day.
Dr. Bartels noted that this study “reported unadjusted rates, without controlling for traditional CVD risk factors, for instance, so it will be interesting to see that report after full analysis and peer review as well.” She added that the rates in the VA study may even be higher if there were uncounted cardiovascular events or deaths outside the VA.
“The key take away is that glucocorticoids have dose-related cardiovascular risk shown in both duration and dose of use now in these three large U.S. cohorts,” Dr. Bartels said. “Providers need to counsel patients in judicious use of glucocorticoids, favoring the role of biologic and nonbiologic DMARDs while balancing unique needs and quality-of-life considerations in our patients.”
The VA retrospective cohort study was funded by the National Institutes of Health, the American Autoimmune Related Diseases Association, the U.S. Department of Veterans Affairs, and the Michigan Institute for Clinical & Health Research. Dr. Wallace and seven other authors reported no disclosures. Several coauthors reported financial ties to multiple pharmaceutical companies. The Medicare/Optum retrospective cohort study was funded by the National Institutes of Health, the Patient-Centered Outcomes Research Institute, and the Rheumatology Research Foundation.

EMPEROR-Preserved findings confirmed in ‘true’ HFpEF patients
Main results from the landmark EMPEROR-Preserved trial, reported in August, established for the first time that treatment with a drug, the sodium-glucose cotransporter 2 inhibitor empagliflozin, could clearly benefit patients with heart failure with preserved ejection fraction (HFpEF).
The only caveat was that EMPEROR-Preserved enrolled patients with a left ventricular ejection fraction of at least 41%, while “true” HFpEF means patients with heart failure and an LVEF of at least 50%, according to recent definitions. About one-third of the 5,988 patients enrolled in EMPEROR-Preserved had an LVEF of 41%-49%, heart failure with mildly reduced ejection fraction.
Secondary analysis from the EMPEROR-Preserved trial has now resolved this ambiguity by showing that, among the 4,005 patients (67%) enrolled in the trial with an LVEF of at least 50%, treatment with empagliflozin (Jardiance) reduced the study’s primary endpoint – cardiovascular death or first hospitalization for heart failure – by a significant 17%, relative to patients who received placebo, dismissing any doubt about the relevance of the overall finding to the subgroup of patients with unmitigated HFpEF.
“This is the first large-scale trial to document meaningful and significant improvements associated with drug therapy in patients with ‘true’ HFpEF,” Stefan D. Anker, MD, said in presenting the results at the American Heart Association scientific sessions.
Streamlining heart failure treatment
The demonstration that empagliflozin is an effective – and safe – treatment for patients with HFpEF not only provides a new treatment for a disorder that until now had no evidence-based intervention, but also streamlines the management approach for treating patients with heart failure with an agent from empagliflozin’s class, the SGLT2 inhibitors, commented Mary Norine Walsh, MD, medical director of the heart failure and cardiac transplantation programs at Ascension St. Vincent Heart Center in Indianapolis.
That’s because empagliflozin has shown significant and consistent benefit across essentially the full range of LVEFs seen in patients with heart failure based on its performance in EMPEROR-Preserved as well as in a mirror-image trial, EMPEROR-Reduced, run in patients with heart failure with reduced ejection fraction.
“Clinicians do not need to stop and assess LVEF with echocardiography or other imaging before they decide on how to treat heart failure patients” with an SGLT2 inhibitor, noted Dr. Walsh, a designated discussant for the report. “Clinicians who are busy can now refer less to LVEF than to the patient’s phenotype.”
Treatment prevents hospitalization for heart failure
The more-detailed data reported by Dr. Anker also strengthened the case that the benefit from empagliflozin in patients with an LVEF of at least 50% mostly came from a reduction in hospitalizations for heart failure (HHF), which dropped following start of empagliflozin treatment by a relative 22%, compared with placebo for first HHF, a significant decline, and by a relative 17% for total HHF, a reduction that missed significance in this secondary analysis. The other half of the primary endpoint, cardiovascular death, declined by a nonsignificant 11% with empagliflozin treatment, compared with placebo in patients with clear-cut HFpEF.
The significant reduction in first HHF is, by itself, sufficient reason to use empagliflozin (or possibly a different SGLT2 inhibitor) in patients with HFpEF, maintained Clyde W. Yancy, MD, professor and chief of cardiology at Northwestern Medicine in Chicago.
“Attenuated HHF is a meaningful outcome,” stressed Dr. Yancy, also a discussant for the study. “This is the first time we’ve had evidence supporting that we can change the natural history of patients with HFpEF. While we still need to find interventions that save lives, we cannot overlook that this treatment can improve morbidity, and we cannot overlook that patient quality of life is better.”
Further benefits in patients with an LVEF of at least 50%
Dr. Anker, professor of cardiology and metabolism at Charité Medical University in Berlin, also reported results from several other analyses that further defined the effect of empagliflozin on clinical outcomes of patients with “true” HFpEF:
- The impact of empagliflozin, compared with placebo, for reducing both the study’s combined, primary outcome as well as total HHF was statistically consistent across all strata of LVEF, from 50% to greater than 70%. However, both outcome measures also showed a puzzling loss of benefit among patients with an LVEF of 65%-69%. In prior reports, a researcher on the EMPEROR-Preserved team, Milton Packer, MD, speculated that some patients in this LVEF stratum might not actually have had heart failure but instead had a different disorder that mimicked heart failure in clinical presentation, such as atrial fibrillation.
- Patients’ quality of life as measured by the Kansas City Cardiomyopathy Questionnaire showed a consistent benefit from empagliflozin treatment, compared with placebo, both in patients with an LVEF of at least 50% as well as in those with an LVEF of 41%-49%. In both subgroups the adjusted mean difference from placebo was significant and about 1.5 points.
- Patients showed a significant improvement in average New York Heart Association functional class while on treatment, and a strong trend toward less deterioration in functional class while on treatment.
- Deterioration of renal function on treatment slowed by an average 1.24 mL/min per 1.73 m2 per year in patients on empagliflozin, compared with placebo, in the subgroup with an LVEF of at least 50%.
Dr. Anker also reported the primary outcome and component results for the subgroup of patients with a baseline LVEF of 41%-49%. These patients had what looked like a “bigger magnitude” of effect from treatment, he noted, showing a significant 29% relative decline in the primary endpoint, compared with placebo-treated patients, and a significant 42% relative drop in first HHF and a significant 43% relative decline in total HHF, compared with placebo.
The primary analysis from EMPEROR-Preserved, which included all 5,988 randomized patients with heart failure and an LVEF of 41% or greater, showed a significant reduction in the combined, primary endpoint with empagliflozin treatment of 21%, compared with control patients during a median follow-up of about 26 months. The absolute rate reduction of the combined primary endpoint was 3.3% during 26-months’ follow-up. Statistical tests have shown no heterogeneity of this effect by diabetes status (49% of patients had diabetes), nor by renal function down to an estimated glomerular filtration rate at entry as low as 20 mL/min per 1.73 m2.
EMPEROR-Preserved was sponsored by Boehringer Ingelheim and Lilly, the two companies that market empagliflozin (Jardiance). Dr. Anker has been a consultant to Boehringer Ingelheim as well as to Abbott Vascular, Bayer, Brahms, Cardiac Dimensions, Cordio, Novartis, Servier, and Vifor. Dr. Walsh and Dr. Yancy had no disclosures.
Main results from the landmark EMPEROR-Preserved trial, reported in August, established for the first time that treatment with a drug, the sodium-glucose cotransporter 2 inhibitor empagliflozin, could clearly benefit patients with heart failure with preserved ejection fraction (HFpEF).
The only caveat was that EMPEROR-Preserved enrolled patients with a left ventricular ejection fraction of at least 41%, while “true” HFpEF means patients with heart failure and an LVEF of at least 50%, according to recent definitions.

FROM AHA2021
Ticagrelor reversal agent achieves quick hemostasis: REVERSE-IT
The experimental monoclonal antibody bentracimab, which reverses the antiplatelet effects of ticagrelor, appears to be heading toward regulatory approval, on the basis of an interim analysis of the phase 3 REVERSE-IT trial.
“Rates of effective hemostasis were adjudicated as good or excellent in more than 90% of cases with no drug-related serious adverse events or allergic or infusion-related reactions,” reported Deepak L. Bhatt, MD, at the American Heart Association scientific sessions.
The interim analysis of this nonrandomized, single-arm study was requested by the Food and Drug Administration, which is considering a conditional accelerated approval of bentracimab (formerly PB2452) if efficacy and safety are established.
Upon administration, bentracimab binds to free ticagrelor so that ticagrelor cannot bind to the P2Y12 platelet receptor. This interrupts one of the key steps in the pathway of platelet aggregation.
REVERSE-IT is still enrolling patients. This interim analysis was conducted with the first 150 patients who met eligibility criteria and were treated. Of these, 142 patients were enrolled for an urgent surgical indication and 8 for a major bleeding indication. After some exclusions for lack of urgency and reclassifications following adjudication, there were 113 surgical cases and 9 major bleeding patients evaluable for hemostasis.
Platelet function assays test reversal
On the primary reversal endpoint, which was restoration of activity on the proprietary platelet function assays Verify Now and PRUTest, a rapid restoration of platelet function was achieved in both surgical and major-bleeding patients. Platelet reactivity climbed to near normal levels within 10 minutes of administration, and peak effects were sustained through the first 24 hours after administration.
On the basis of the platelet function assays, the pattern of response to bentracimab was “very similar in the surgical and bleeding patients,” reported Dr. Bhatt, executive director of interventional cardiovascular programs at Brigham and Women’s Health, Boston.
The effect was also consistent across a broad array of prespecified subgroups, including stratifications by age, renal function, time from last dose of ticagrelor, race, and the presence of comorbidities, such as diabetes, renal dysfunction, hypertension, and history of MI.
Hemostasis documented in all but one patient
Adjudicated hemostasis was achieved in 100% of the 113 urgent surgical patients evaluated. In the nine major bleeding patients, six achieved excellent hemostasis and one achieved good hemostasis. One had poor hemostasis, and one was unevaluable.
Platelet rebound following bentracimab administration, measured by mean platelet volume, was not observed.
There were no serious adverse events, allergic reactions, or serious infusion-related reactions associated with the administration of bentracimab, Dr. Bhatt said.
While Dr. Bhatt acknowledged that the number of patients in the major-bleeding subgroup was small, he noted that the reduction in platelet reactivity relative to baseline was still significant. In addition, he characterized urgent surgery as “an excellent model of bleeding” and pointed out the consistency of results in the surgical and major-bleeding groups.
The interim results are also consistent with phase 1 data published 2 years ago, and with the subsequent phase 2 studies. All of these data are now under regulatory review both in the United States and in Europe, according to Dr. Bhatt.
No good current options for reversal
Evidence of efficacy and safety is encouraging, because current options for urgently reversing ticagrelor are “disappointing,” according to the invited discussant Gilles Montalescot, MD, PhD, professor of cardiology, Pitié-Salpêtrière Hôpital, Paris.
“Platelet transfusion has some value for clopidogrel and prasugrel, but it does not work for ticagrelor,” said Dr. Montalescot, referring to two other P2Y12 inhibitors. Substantiating the need for a reversal agent, he identified several other strategies that have proven ineffective, such as desmopressin and sorbent hemadsorption.
Overall, Dr. Montalescot acknowledged the need for a highly effective ticagrelor reversal agent, but he did have some criticisms of REVERSE-IT. For one, he was not convinced about the design.
“What was unethical in having a control group?” he asked, suggesting that it was feasible and would have addressed issues of relative efficacy and safety.
For example, the authors concluded that none of the thrombotic events were likely to be treatment related, but “four events occurred immediately after reversal without an alternate explanation,” Dr. Montalescot pointed out. “Was this a signal or background noise?”
Nevertheless, he agreed that the interim phase 3 data are consistent with the previously reported phase 2 studies, and he reiterated that a strategy to reverse ticagrelor’s effects is an important unmet need.
Dr. Bhatt has a financial relationship with a large number of pharmaceutical companies, including PhaseBio, which provided funding for the REVERSE-IT trial. Dr. Montalescot reported financial relationships with Amgen, AstraZeneca, Bayer, Boehringer Ingelheim, Boston Scientific, Bristol-Myers Squibb, Cell-Prothera, CSL-Behring, Europa, Idorsia, Servicer, Medtronic, Merck Sharpe & Dohme, Novartis, Pfizer, Quantum Genomics, and Sanofi-Aventis.

“What was unethical in having a control group?” he asked, suggesting that it was feasible and would have addressed issues of relative efficacy and safety.
For example, the authors concluded that none of the thrombotic events were likely to be treatment related, but “four events occurred immediately after reversal without an alternate explanation,” Dr. Montalescot pointed out. “Was this a signal or background noise?”
Nevertheless, he agreed that the interim phase 3 data are consistent with the previously reported phase 2 studies, and he reiterated that a strategy to reverse ticagrelor’s effects is an important unmet need.
Dr. Bhatt has a financial relationship with a large number of pharmaceutical companies, including PhaseBio, which provided funding for the REVERSE-IT trial. Dr. Montalescot reported financial relationships with Amgen, AstraZeneca, Bayer, Boehringer Ingelheim, Boston Scientific, Bristol-Myers Squibb, Cell-Prothera, CSL-Behring, Europa, Idorsia, Servicer, Medtronic, Merck Sharpe & Dohme, Novartis, Pfizer, Quantum Genomics, and Sanofi-Aventis.

Oral daprodustat safely improves anemia in chronic kidney disease
both in those who are dialysis dependent and those who are not, in a pair of phase 3, randomized trials that together included more than 6,800 patients.
“Daprodustat could represent an oral alternative to ESAs for treating anemia of CKD in both dialysis and nondialysis patients,” said Ajay K. Singh, MBBS, who presented results from both studies at the annual meeting of the American Society of Nephrology.
Concurrently, reports on the trial with dialysis-dependent patients, ASCEND-D, and on the trial with non–dialysis-dependent patients, ASCEND-ND, appeared online in the New England Journal of Medicine.
Singh highlighted that the results prove the noninferiority of oral daprodustat to the injected ESAs – epoetin alfa (Epogen, Procrit) or darbepoetin alfa (Aranesp) – used as the comparator agents in the two trials for the adjudicated safety outcome of major adverse cardiovascular events (MACE). In addition, results from the two studies also showed “no safety signals that pop out, and no new safety signals observed,” he said.
Those were telling assessments, given that two other agents from the same drug class – the hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs) roxadustat and vadadustat – have been hobbled by safety concerns that cropped up in their pivotal trials.
A class with a history of safety concerns
The HIF-PHI roxadustat received an overwhelming negative reaction from an advisory committee to the Food and Drug Administration in July 2021 because of safety concerns, although it was approved in the European Union.
And results from a phase 3 trial of the HIF-PHI agent vadadustat reported in April, showed that, in patients with non–dialysis-dependent CKD treated with vadadustat the MACE incidence failed to meet the trial’s criterion for noninferiority, compared with patients treated with the ESA darbepoetin alfa.
In contrast, the safety of daprodustat, based on the results reported so far “is looking really good,” commented Jay B. Wish, MD, a nephrologist and professor at Indiana University in Indianapolis who was not involved with the study.
“You never know what’s behind the curtain, but what’s out there [for daprodustat] seems very encouraging,” Dr. Wish said in an interview.
He cited in particular the data reported by Dr. Singh on thromboembolic events and vascular access thrombosis, adverse effects that were especially problematic for roxadustat. The report by Dr. Singh specifically called out these numbers and showed numerical reductions in these rates, compared with ESA-treated patients among those on dialysis, and small increases among those on daprodustat, compared with ESA treatment among those not on dialysis.
In ASCEND-ND, nonfatal thromboembolic events during median follow-up of 1.9 years occurred 97 times (in 3.0% of patients) among 1,917 patients treated with daprodustat and 65 times (in 2.4% of patients) among 1,935 patients treated with darbepoetin alfa, reported Dr. Singh, a nephrologist at Brigham and Women’s Hospital in Boston. Vascular access thrombosis in ASCEND-ND occurred 69 times in 2.1% of patients on daprodustat and 42 times in 1.5% of patients who received the ESA.
Drugs from the HIF-PHI class for anemia in patients with CKD “have now been evaluated in a number of phase 3, randomized, controlled trials. Initial results in patients with dialysis-dependent CKD are promising, but in patients with non–dialysis-dependent CKD questions about indications and safety warrant further investigations,” Patrick Parfrey, MD, commented in an editorial that accompanied the ASCEND-D and ASCEND-ND reports.
Safety signals seen for cancers and erosions
Dr. Parfrey cited two particular safety findings, both seen in ASCEND-ND. One was a numerically higher rate of cancer-related death, or tumor progression or recurrence, among the daprodustat recipients (3.7%), compared with the controls who received an ESA in the ASCEND-ND trial (2.5%), representing a significant relative risk of 1.47.
In contrast, in ASCEND-D this cancer safety measure showed a reduced relative risk with daprodustat of 0.92 relative to the ESA comparators.
“The safety of HIF-PHIs from the cancer perspective will require longer follow-up, individual patient meta-analysis ... and postmarketing surveillance,” wrote Dr. Parfrey, a nephrologist and professor at Memorial University, St. John’s, Nfld.
Elevated cancer rates are a hypothetical concern with agents from the HIF-PHI class because of their potential for increasing angiogenesis that could support tumor growth, said Dr. Wish.
Dr. Parfrey also cited another safety signal in ASCEND-ND, a higher rate of esophageal or gastric erosions on daprodustat (3.6%), compared with those on darbepoetin alfa (2.1%), with a significant relative risk of 1.7.
Again, this signal was absent in ASCEND-D, where esophageal or gastric erosions were more common in the patients on an ESA, with a relative risk reduction in favor of daprodustat of 0.74.
But even if these cancer and erosion effects in nondialysis patients on daprodustat are real, “these things don’t sink a drug. You deal with them in the drug’s label,” commented Dr. Wish.
During the FDA’s advisory committee meeting on roxadustat, agency staffers especially cited apparent excess rates of thrombosis and seizures associated with the drug. In both ASCEND-D and ASCEND-ND the rate of seizures in both treatment arms was less than 1%.
Dr. Wish speculated that the differences seen between roxadustat and daprodustat are likely more related to the design of their respective studies rather than real drug differences within the class.
Perhaps most importantly, the roxadustat trials in patients with CKD and not requiring dialysis compared the drug against placebo, while in ASCEND-ND the comparator was darbepoetin alfa. He also suggested that patients on dialysis receiving roxadustat may have been “overdosed,” resulting in faster increases in hemoglobin and higher peak levels.
Big potential for oral anemia treatment
In general, having an oral alternative for treating anemia in patients with CKD will be a significant advance, said Dr. Wish, especially for patients not on dialysis as well as for the rapidly growing number of patients who receive dialysis at home.
U.S. patients with CKD who do not require dialysis “often don’t get treated for anemia because it is so cumbersome” to use ESAs on patients not treated at a centralized clinic, said Dr. Wish, medical director of the outpatient dialysis unit at Indiana University Hospital, Indianapolis. “It’s a logistical nightmare.”
On the other hand, Wish did not see nearly as great a need for an oral therapy for anemia in patients treated at a dialysis clinic.
Patients who receive an ESA during their three-times weekly dialysis session usually do very well. “It’s not broken, and does not need to get fixed,” Dr. Wish said.
ASCEND-D and ASCEND-ND were sponsored by GlaxoSmithKline, the company developing daprodustat. Dr. Singh has been a consultant to GlaxoSmithKline and owns stock in Gilead. Dr. Wish has been a consultant to GlaxoSmithKline, as well as an adviser to AstraZeneca, Akebia, Otsuka, Vifor, and Rockwell Medica, and he has been a speaker on behalf of AstraZeneca and Akebia.

FROM KIDNEY WEEK 2021
Adding rituximab to belimumab offers no help for lupus
Adding a single cycle of rituximab to belimumab (Benlysta) did not improve disease control for patients with systemic lupus erythematosus (SLE) in comparison with belimumab alone in a phase 3, randomized, controlled trial.
Among patients with SLE who were randomly assigned to receive belimumab with either rituximab, placebo, or standard care, there were no statistically significant differences between the rituximab and placebo arms for the primary endpoint of the proportion of patients with disease control at week 52 or in the secondary endpoints of clinical remission at week 64 or disease control at week 104, Cynthia Aranow, MD, reported in a late-breaking poster session presented during the virtual annual meeting of the American College of Rheumatology.
“Using a new, clinically meaningful endpoint underscores the efficacy of belimumab for disease control, with some patients maintaining disease control with considerable reductions in steroids, and no immunosuppressants,” said Dr. Aranow, a rheumatologist specializing in SLE and RA in New York and director of the Clinical Autoimmunity Center of Excellence at Feinstein Institutes for Medical Research, Manhasset, N.Y.
Use of the combination of belimumab and rituximab was, however, associated with significant improvement over belimumab and placebo in several secondary efficacy endpoints.
Investigators in the randomized, controlled trial, dubbed BLISS-BELIEVE, had previously published a rationale for sequential therapy with belimumab, a human monoclonal antibody that binds to soluble B-lymphocyte stimulator, and rituximab, a B-cell–depleting anti-CD20 monoclonal antibody.
“These biologics, which operate through complementary mechanisms, might result in an enhanced depletion of circulating and tissue-resident autoreactive B lymphocytes when administered together. Thus, belimumab and rituximab combination may be a highly effective treatment of SLE,” they wrote in an article published in 2019 in BMJ Open.
Three-arm trial
The investigators screened 396 patients, of whom 292 were randomly assigned in a 1:2:1 ratio to receive either subcutaneous belimumab 200 mg/wk plus intravenous placebo at weeks 4 and 6 (BEL/PBO, 72 patients), belimumab plus IV rituximab 1,000 mg at weeks 4 and 6 (BEL/RTX, 144 patients), or open-label belimumab plus standard therapy. Patients were allowed to continue taking antimalarial and nonsteroidal anti-inflammatory drugs throughout the study.
The primary disease-control endpoint was defined as a Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score of 2 or less, achieved without other immunosuppression, equivalent to that achieved with prednisone 5 mg/day or less.
As noted before, there were no significant differences between the BEL/RTX and BEL/PBO arms in either disease control at week 52 or in the secondary endpoints of clinical remission at week 64 (SLEDAI-2K score, 0) or in the proportion of patients with disease control at week 104.
However, use of BEL/RTX was associated with a significantly longer duration of disease control through 52 weeks than was BEL/PBO (mean, 105.4 days vs. 60.1 days; P = .0188) and with a large SLEDAI-2K mean change from baseline at week 104 (–7.2 vs 5.1; P = .0033).
In addition, there was a trend toward a shift in proteinuria from baseline high (>0.5 g/24 h) to normal in the BEL/RTX group at week 52 and a significantly greater shift at week 104 (P = .0085).
The overall adverse event profiles were generally consistent with those of the individual agents, although serious infections and infestations occurred more frequently with BEL/RTX than BEL/PBO.
Further analyses planned to look for subgroups that benefit
In a poster discussion session, Akshat Khanna, PhD, of Newtown, Pa., a consultant with Effimed Life Sciences Research, asked Dr. Aranow about the rationale for giving rituximab and belimumab concurrently and noted that, in the BEAT-LUPUS and CALIBRATE trials, anti-CD20 agents were given first, followed by belimumab, to prevent activation of humoral immunity.
“The two B-cell agents were given sequentially. Belimumab was given first to maximize the effect of peripheral B-cell depletion and [was] then continued after rituximab to suppress the elevation [of B-lymphocyte stimulator] that occurs after rituximab monotherapy. We used this approach (instead of that used in CALIBRATE and BEAT LUPUS), as we thought this might be more efficacious,” she explained.
When asked whether there were subgroups of patients who might still benefit from the combination, compared with belimumab alone, Dr. Aranow replied: “There may be individual patients in which it might be considered. Further analyses of the data are ongoing/planned.”
The study was supported by GlaxoSmithKline. Dr. Aranow has received grant/research support from GlaxoSmithKline and has consulted for Bristol-Myers Squibb. Dr. Khanna has disclosed no relevant financial relationships.

Investigators in the randomized, controlled trial, dubbed BLISS-BELIEVE, had previously published a rationale for sequential therapy with belimumab, a human monoclonal antibody that binds to soluble B-lymphocyte stimulator, and rituximab, a B-cell–depleting anti-CD20 monoclonal antibody.
“These biologics, which operate through complementary mechanisms, might result in an enhanced depletion of circulating and tissue-resident autoreactive B lymphocytes when administered together. Thus, belimumab and rituximab combination may be a highly effective treatment of SLE,” they wrote in an article published in 2019 in BMJ Open.
Three-arm trial
The investigators screened 396 patients, of whom 292 were randomly assigned in a 1:2:1 ratio to receive either subcutaneous belimumab 200 mg/wk plus intravenous placebo at weeks 4 and 6 (BEL/PBO, 72 patients), belimumab plus IV rituximab 1,000 mg at weeks 4 and 6 (BEL/RTX, 144 patients), or open-label belimumab plus standard therapy. Patients were allowed to continue taking antimalarial and nonsteroidal anti-inflammatory drugs throughout the study.
The primary disease-control endpoint was defined as a Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score of 2 or less, achieved without other immunosuppression, equivalent to that achieved with prednisone 5 mg/day or less.
As noted before, there were no significant differences between the BEL/RTX and BEL/PBO arms in either disease control at week 52 or in the secondary endpoints of clinical remission at week 64 (SLEDAI-2K score, 0) or in the proportion of patients with disease control at week 104.
However, use of BEL/RTX was associated with a significantly longer duration of disease control through 52 weeks than was BEL/PBO (mean, 105.4 days vs. 60.1 days; P = .0188) and with a large SLEDAI-2K mean change from baseline at week 104 (–7.2 vs 5.1; P = .0033).
In addition, there was a trend toward a shift in proteinuria from baseline high (>0.5 g/24 h) to normal in the BEL/RTX group at week 52 and a significantly greater shift at week 104 (P = .0085).
The overall adverse event profiles were generally consistent with those of the individual agents, although serious infections and infestations occurred more frequently with BEL/RTX than BEL/PBO.
Further analyses planned to look for subgroups that benefit
In a poster discussion session, Akshat Khanna, PhD, of Newtown, Pa., a consultant with Effimed Life Sciences Research, asked Dr. Aranow about the rationale for giving rituximab and belimumab concurrently and noted that, in the BEAT-LUPUS and CALIBRATE trials, anti-CD20 agents were given first, followed by belimumab, to prevent activation of humoral immunity.
“The two B-cell agents were given sequentially. Belimumab was given first to maximize the effect of peripheral B-cell depletion and [was] then continued after rituximab to suppress the elevation [of B-lymphocyte stimulator] that occurs after rituximab monotherapy. We used this approach (instead of that used in CALIBRATE and BEAT LUPUS), as we thought this might be more efficacious,” she explained.
When asked whether there were subgroups of patients who might still benefit from the combination, compared with belimumab alone, Dr. Aranow replied: “There may be individual patients in which it might be considered. Further analyses of the data are ongoing/planned.”
The study was supported by GlaxoSmithKline. Dr. Aranow has received grant/research support from GlaxoSmithKline and has consulted for Bristol-Myers Squibb. Dr. Khanna has disclosed no relevant financial relationships.
