Heart Failure

The Food and Drug Administration has come through with the widely anticipated approval of dapagliflozin (Farxiga, AstraZeneca) for heart failure and reduced ejection fraction (HFrEF), adding to the rich array of medications lately available for this indication.

The approval follows the agency’s priority review of the sodium-glucose cotransporter 2 (SGLT2) inhibitor for reducing the risk of cardiovascular death and heart-failure hospitalization in adults with HFrEF following last year’s seminal results of the DAPA-HF trial.

In that study, treatment with dapagliflozin led to about a one-fourth reduction in risk of a primary endpoint consisting primarily of CV death or heart failure hospitalization in patients with chronic HFrEF, in both those with and without diabetes. The randomized, placebo-controlled trial had entered more than 4,700 patients.

Soon after, the FDA approved dapagliflozin for reducing the risk of heart failure hospitalization in adults with type 2 diabetes and other CV risk factors.

And of course, dapagliflozin – traditionally viewed only as an antidiabetic agent – has long been indicated for improvement of glycemic control in adults with type 2 diabetes.

The latest approval for patients with New York Heart Association functional class III-IV HFrEF makes dapagliflozin the only SGLT2 inhibitor to be indicated for heart failure in the absence of diabetes.

Soon after the DAPA-HF results had been unveiled at a major meeting, heart failure expert Christopher O’Connor, MD, expressed concern that dapagliflozin’s uptake for patients with HFrEF would be slow once it gained approval for patients without diabetes.

“We have to think of this as a drug that you would prescribe like an ACE inhibitor, or a beta-blocker, or a mineralocorticoid receptor antagonist, or sacubitril/valsartan [Entresto, Novartis],” Dr. O’Connor, of the Inova Heart and Vascular Institute, Falls Church, Va., said in an interview.

Dr. O’Connor was not associated with DAPA-HF and had previously disclosed no relevant financial relationships.

A just-launched study of the type 2 diabetes agent dapagliflozin (Farxiga, AstraZeneca) in patients with mild to moderate COVID-19 is raising eyebrows, given that several expert groups have advised that drugs in this class – the sodium-glucose cotransporter 2 (SGLT2) inhibitors – be stopped in all patients hospitalized with COVID-19 because of the increased risk for diabetic ketoacidosis (DKA).

The randomized, double-blind, placebo-controlled, phase 3 Dapagliflozin in Respiratory Failure in Patients With COVID-19 (DARE-19) study is sponsored by AstraZeneca and Saint Luke’s Mid America Heart Institute.

The trial will assess whether dapagliflozin reduces the risks of disease progression, clinical complications, and death because of COVID-19 in patients with type 2 diabetes, cardiovascular disease, and/or mild to moderate chronic kidney disease (CKD).

“Dapagliflozin has demonstrated cardio- and renal-protective benefits and improved outcomes in high-risk patients with type 2 diabetes, heart failure with reduced ejection fraction, and CKD,” said the principal investigator of DARE-19, Mikhail N. Kosiborod, MD, a cardiologist at Saint Luke’s Mid America Heart Institute, Kansas City, Mo.

And “patients with COVID-19 and underlying cardiometabolic disease appear to be at the highest risk of morbid complications,” he explained in an AstraZeneca statement.

“Through DARE-19, we hope to decrease the severity of illness, and prevent cardiovascular, respiratory, and kidney decompensation, which are common in patients with COVID-19,” Dr. Kosiborod continued.

However, advice to stop SGLT2 inhibitors in patients hospitalized with COVID-19 because of its associated DKA risk has come from several channels.

These include initial guidance from Diabetes UK; experts who spoke during an American Diabetes Association webinar; and most recently, an international panel of diabetes experts.

Some clinicians went so far as to say that they view the trial as potentially dangerous, while others said they could see some logic to it, as long as it is carefully managed.
 

“A dangerous proposition – a DARE I would not take”

Partha Kar, MD, of Portsmouth Hospitals NHS Trust and national clinical director of diabetes at NHS England, said in an interview: “It’s interesting to see [AstraZeneca] embark on a study with a particular class of drug whereby ... [in] the UK we have said that if you get sent to hospital with COVID-19 you should stop [SGLT2 inhibitors] immediately.”

It “sounds like a risky proposition to go ahead with, [and it] definitely made me raise an eyebrow,” he added.

Nephrologist Bruce R. Leslie, MD, of Seventh Doctor Consulting in Princeton, N.J., agreed with Dr. Kar.

“Giving SGLT2 inhibitors to patients in the DARE-19 study is a dangerous proposition because these drugs can induce ketoacidosis during the stress of acute illness such as COVID-19. ... Moreover, ketoacidosis is associated with hypercoagulability which could be especially dangerous in COVID-19, given that it has been causing thrombophilia with large-vessel occlusive strokes in young patients,” he said in an interview.

“One wonders how these risks were assessed by the authorities that approved the DARE-19 study,” said Dr. Leslie, who formerly worked for Bristol-Myers Squibb.

“How does the sponsor intend to secure informed consent given the risks? This is a DARE I would not take,” he said.

Asked to address these concerns, Dr. Kosiborod said in an interview that “the DARE-19 trial will assess both the efficacy and the safety of dapagliflozin in this patient population in a closely monitored environment of a rigorously designed randomized clinical trial. The trial protocol excludes patients with type 1 diabetes or at high risk for DKA.

“Furthermore, the protocol includes detailed specific instructions to ensure careful monitoring for DKA, including frequent assessments of acid-base status in the hospital setting. The safety data will be closely monitored by an independent data-monitoring committee,” he continued.

Dr. Kosiborod also pointed out that there is “no systematically collected information on the use of dapagliflozin or any other SGLT2 inhibitor in patients being treated for COVID-19, including the associated potential benefits, possible risks such as DKA, and the balance of these potential benefits and risks.”

DARE-19 design: Several outcomes will be examined

The DARE-19 trial is designed to enroll 900 adults with confirmed SARS-CoV-2 infection and oxygen saturation of 94% or greater.

Inclusion criteria include a medical history of hypertension, type 2 diabetes, atherosclerotic cardiovascular disease, heart failure, and/or stage 3-4 CKD. Exclusion criteria include current SGLT2 inhibitor treatment, type 1 diabetes, severe CKD, and severe COVID-19.

Dapagliflozin is approved in the EU for use in some patients with type 1 diabetes; this is not the case in the United States, although SGLT2 inhibitors in general are sometimes used off label in these patients.

Patients in DARE-19 will be randomized to 10 mg/day dapagliflozin or placebo for 30 days, in addition to standard care, in participating hospital. Primary outcomes are time to first occurrence of either death or new or worsened organ dysfunction, including respiratory decompensation, new or worsening heart failure, requirement for vasopressor therapy, ventricular tachycardia, and renal failure.

Secondary outcomes include a composite of time to death from any cause, time to new/worsened organ dysfunction, clinical status at day 30, and time to hospital discharge.

Rationale for the study

Irl B. Hirsch, MD, professor and diabetes treatment and teaching chair at the University of Washington, Seattle, said in an interview that he does see some logic to the trial.

Admitting that he doesn’t know much about “COVID-19 cardiomyopathy” – which would be one of the targets of dapagliflozin – other than it is quite common, he said that this, along with the potential renal benefits of dapagliflozin in the setting of COVID-19, make the study “intriguing.”

“Perhaps there is some rationale to it,” he said. However, “my concern is these sick COVID-19 patients are often acidemic, and besides the very complex acid-base challenges we see with intubated patients, these patients likely have combination lactic and ketoacidemia, the latter at least some from starvation.

“Still, if enough dextrose and insulin are provided to prevent ketoacid accumulation, my guess is it would do at least as well as hydroxychloroquine,” he said.

And Simon Heller, MD, professor of clinical diabetes at the University of Sheffield (England), said in an interview: “I think it is quite a brave study, mainly because of the increased risk of DKA.

“However, on the basis that these patients will be carefully monitored, the risk of DKA shouldn’t be great. I think it is important that patients with type 2 diabetes can participate whenever possible in such trials,” he said.

The estimated completion date for DARE-19 is December 2020.

Redo transcatheter aortic valve replacement (TAVR) is a reasonably safe and effective option for selected patients with valve dysfunction after TAVR, new registry data suggest.

“Redo TAVR is about to become a much more common procedure and it’s reassuring to see that the outcomes that can be achieved by these procedures are quite good,” said Uri Landes, MD, Vancouver General Hospital, British Columbia, Canada.

Landes and colleagues reported results from the Redo-TAVR Registry in the April 28 issue of the Journal of the American College of Cardiology.

The Redo-TAVR Registry is an investigator-initiated effort designed to collect information on patients who undergo a second TAVR within a dysfunctional transcatheter heart valve (THV).

From 63,876 TAVR procedures done at 37 participating centers, 212 (0.33%) were redo-TAVR procedures. Seventy-four of the redo procedures were done within 1 year of the initial TAVR and the remaining 138 were beyond 1 year. Median time from TAVR-to-redo-TAVR for these two groups was 68 (38 to 154) days and 5 (3 to 6) years, respectively.

“It’s important to understand that this is probably a highly selected group of patients and these numbers do no reliably reflect the ratio of patients who will need a redo TAVR,” said Landes in an interview with theheart.org | Medscape Cardiology.

“We don’t know how many patients were excluded from redo TAVR because of prohibitive anatomical factors, such as an anticipated high risk for coronary occlusion, or a patient prosthesis mismatch. Also, some of these individuals received their THVs more recently, so if they will suffer THV valve dysfunction, it may not have happened yet,” he added.

In the early redo group, the indication for redo-TAVR was most often combined aortic THV stenosis and regurgitation (83.8%). Pure THV stenosis was seen in only 16.2% of patients.

For those with redo procedures after 1 year, THV stenosis was seen in 51 (37.0%) patients and regurgitation or combined stenosis-regurgitation in 86 (62.3%).

Device success using VARC-2 criteria was achieved in 85.1%, with no difference seen between those presenting within or beyond 1 year. Most failures were attributable to high residual gradients (14.1%) or regurgitation (8.9%).

No significant difference was seen in 30-day (94.6% and 98.5%) and 1-year survival (83.6% and 88.3%) in patients who presented within 1 year or later.

At 30-day and 1-year follow-up, residual gradients were 12.6 ± 7.5 mm Hg and 12.9 ± 9.0 mm Hg, respectively. High residual gradients (³20 mm Hg) were seen in about 14% of patients.

Aortic valve areas were 1.63 ± 0.61 cm2 at 30 days and 1.51 ± 0.57 cm2 at 1 year. Regurgitation was mild or less in 91% of patients at both time points.

Periprocedural complication rates were relatively low. There were three strokes (1.4%), one valve malposition (3.3%), two coronary obstructions (0.9%), and 20 new permanent pacemaker implants (9.6%). Importantly, no procedure-related mortality was seen, only one patient converted to open heart surgery, and symptomatic improvements were substantial.

“We are currently working on an analysis that compares TAVI-in-TAVI versus TAVI in surgical valves, and we are happy to see that it appears as if TAVI-in-TAVI outcomes don’t fall short,” said Landes. More analysis is also needed to see if perhaps some THVs work better or worse for redo procedures.

“We also want to understand which of the many combinations of heart valves available are better than others, thinking that supra-annular leaflets inside intra-annular leaflet devices may function differently than vice versa,” said Landes.

Vinod Thourani, MD, chief of cardiovascular surgery at Piedmont Heart Institute, Atlanta, considers these new observational data “reassuring” and “robust,” albeit with some limitations. He was first author on an editorial comment on this paper and spoke to theheart.org | Medscape Cardiology.

“This is unadjudicated registry data but you can’t lie about death and I feel good seeing that if you need a second TAVR inside of a TAVR, your mortality risk is pretty good,” said Thourani.

That said, he questions whether these data can really be extrapolated to lower-risk patients. “I think this is an early snapshot and it’s a relatively big sample, but it’s a selected sample and we don’t know how many patients needed redo TAVR and didn’t get it or didn’t want it,” he added.

On the comforting side, there has been ongoing concern that a redo procedure that involves “propping open” a degenerated TAVR prosthesis’s leaflets with a new TAVR valve may occlude the coronary ostium by closing the flow within the open cells.

“Luckily, the investigators show an extremely low risk of coronary obstruction of only 0.9% in an anatomically high-risk patient population,” he said. This incidence, however, may increase as the use of TAVR rises in younger and less risky patients, he added.

Thourani would also like to see a longer follow-up on these patients. Median follow-up post redo TAVR was 15 months in this analysis.

“What I think we need to concentrate on as we do these studies is the life-long management of aortic stenosis wherein we try to minimize the overall number of invasive procedures as much as we can,” said Thourani.

Landes reported no conflict of interest. Thourani reported he is an advisor and/or researcher for Abbott Vascular, Boston Scientific, and Edwards Lifesciences.

Redo transcatheter aortic valve replacement (TAVR) is a reasonably safe and effective option for selected patients with valve dysfunction after TAVR, new registry data suggest.

“Redo TAVR is about to become a much more common procedure and it’s reassuring to see that the outcomes that can be achieved by these procedures are quite good,” said Uri Landes, MD, Vancouver General Hospital, British Columbia, Canada.

Landes and colleagues reported results from the Redo-TAVR Registry in the April 28 issue of the Journal of the American College of Cardiology.

The Redo-TAVR Registry is an investigator-initiated effort designed to collect information on patients who undergo a second TAVR within a dysfunctional transcatheter heart valve (THV).

From 63,876 TAVR procedures done at 37 participating centers, 212 (0.33%) were redo-TAVR procedures. Seventy-four of the redo procedures were done within 1 year of the initial TAVR and the remaining 138 were beyond 1 year. Median time from TAVR-to-redo-TAVR for these two groups was 68 (38 to 154) days and 5 (3 to 6) years, respectively.

“It’s important to understand that this is probably a highly selected group of patients and these numbers do no reliably reflect the ratio of patients who will need a redo TAVR,” said Landes in an interview with theheart.org | Medscape Cardiology.

“We don’t know how many patients were excluded from redo TAVR because of prohibitive anatomical factors, such as an anticipated high risk for coronary occlusion, or a patient prosthesis mismatch. Also, some of these individuals received their THVs more recently, so if they will suffer THV valve dysfunction, it may not have happened yet,” he added.

In the early redo group, the indication for redo-TAVR was most often combined aortic THV stenosis and regurgitation (83.8%). Pure THV stenosis was seen in only 16.2% of patients.

For those with redo procedures after 1 year, THV stenosis was seen in 51 (37.0%) patients and regurgitation or combined stenosis-regurgitation in 86 (62.3%).

Device success using VARC-2 criteria was achieved in 85.1%, with no difference seen between those presenting within or beyond 1 year. Most failures were attributable to high residual gradients (14.1%) or regurgitation (8.9%).

No significant difference was seen in 30-day (94.6% and 98.5%) and 1-year survival (83.6% and 88.3%) in patients who presented within 1 year or later.

At 30-day and 1-year follow-up, residual gradients were 12.6 ± 7.5 mm Hg and 12.9 ± 9.0 mm Hg, respectively. High residual gradients (³20 mm Hg) were seen in about 14% of patients.

Aortic valve areas were 1.63 ± 0.61 cm2 at 30 days and 1.51 ± 0.57 cm2 at 1 year. Regurgitation was mild or less in 91% of patients at both time points.

Periprocedural complication rates were relatively low. There were three strokes (1.4%), one valve malposition (3.3%), two coronary obstructions (0.9%), and 20 new permanent pacemaker implants (9.6%). Importantly, no procedure-related mortality was seen, only one patient converted to open heart surgery, and symptomatic improvements were substantial.

“We are currently working on an analysis that compares TAVI-in-TAVI versus TAVI in surgical valves, and we are happy to see that it appears as if TAVI-in-TAVI outcomes don’t fall short,” said Landes. More analysis is also needed to see if perhaps some THVs work better or worse for redo procedures.

“We also want to understand which of the many combinations of heart valves available are better than others, thinking that supra-annular leaflets inside intra-annular leaflet devices may function differently than vice versa,” said Landes.

Vinod Thourani, MD, chief of cardiovascular surgery at Piedmont Heart Institute, Atlanta, considers these new observational data “reassuring” and “robust,” albeit with some limitations. He was first author on an editorial comment on this paper and spoke to theheart.org | Medscape Cardiology.

“This is unadjudicated registry data but you can’t lie about death and I feel good seeing that if you need a second TAVR inside of a TAVR, your mortality risk is pretty good,” said Thourani.

That said, he questions whether these data can really be extrapolated to lower-risk patients. “I think this is an early snapshot and it’s a relatively big sample, but it’s a selected sample and we don’t know how many patients needed redo TAVR and didn’t get it or didn’t want it,” he added.

The sodium-glucose transporter 2 (SGLT-2) inhibitor ertugliflozin broke ranks with the other drugs in its class and failed to produce statistically significant drops in the both the combined incidence of cardiovascular (CV) death or heart failure hospitalization, and the rate of adverse renal outcomes, in the mandated CV outcomes trial run for ertugliflozin with more than 8,200 patients with type 2 diabetes and established CV disease.

Merck, one of the companies that markets the drug, announced the topline results in a quarterly financial report released on April 28, 2020.

According to the report, the results from the ertugliflozin cardiovascular outcomes trial “achieved its primary endpoint of noninferiority for major adverse CV events (MACE), compared to placebo in patients with type 2 diabetes mellitus and established atherosclerotic CV disease,” but “the key secondary endpoints of superiority” of ertugliflozin, compared with placebo, “for time to the composite of CV death or hospitalization for heart failure, CV death alone, and the composite of renal death, dialysis/transplant or doubling of serum creatinine from baseline were not met.”

However, the report added that, “while not a prespecified hypothesis for statistical testing, a reduction in hospitalization for heart failure was observed” with ertugliflozin treatment, and the report further said that the drug’s safety profile in the trial “was consistent with that reported in previous studies.” The statement closed by saying that detailed results from the trial are scheduled to be presented on June 16, 2020, at the virtual American Diabetes Association’s 80th Scientific Sessions.

These results came from the VERTIS CV (Evaluation of Ertugliflozin EffIcacy and Safety Cardiovascular Outcomes) trial, which researchers said in 2018 had administered at least one investigational dose to 8,238 randomized patients at centers in any of 34 countries during two enrollment periods in 2013-2015 and 2016-2017 (Am Heart J. 2018 Dec;206:11-23). The tested agent, ertugliflozin (Steglatro) received Food and Drug Administration marketing approval late in 2017 for the indication of improving glycemic control in patients with type 2 diabetes.

The FDA mandated cardiovascular outcomes trials for new glycemic control drugs in guidance the agency issued in 2008 (the FDA released in March 2020 a draft of updated guidance on this topic).

Other FDA-approved agents from the SGLT2 inhibitor class include canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance), and all three showed evidence for a statistically significant effect on reducing the incidence of CV disease death and heart failure hospitalizations, as well as renal complications (Can J Diabetes. 2020 Feb;44[1]:61-7). The evidence showing that several SGLT2 drugs have important and consistent effects on endpoints like CV death, heart failure hospitalizations, and renal complications has helped propel this class of agents to the forefront of glycemic control treatments. More recently, one agent from this group, dapagliflozin, also significantly cut the rate of heart failure worsening or CV disease death in patients with heart failure with reduced ejection fraction but without diabetes (N Engl J Med. 2019 Nov 21;381[21]:1995-2008). Based on this evidence, the FDA is currently considering adding a new indication for dapagliflozin that would also label it for use in patients with heart failure with reduced ejection fraction but without diabetes.

Concerns about potential risks about the use of spironolactone for acne during the COVID-19 pandemic were raised on social media last month, but spironolactone and other androgen blockers might actually protect against the virus, according to a report in the Journal of the American Academy of Dermatology.

The virus needs androgens to infect cells, and uses androgen-dependent transmembrane protease serine 2 to prime viral protein spikes to anchor onto ACE2 receptors. Without that step, the virus can’t enter cells. Androgens are the only known activator in humans, so androgen blockers like spironolactone probably short-circuit the process, said the report’s lead author Carlos Wambier, MD, PhD, of the department of dermatology at Brown University, Providence, R.I (J Am Acad Dermatol. 2020 Apr 10. doi: 10.1016/j.jaad.2020.04.032).

The lack of androgens could be a possible explanation as to why mortality is so rare among children with COVID-19, and why fatalities among men are higher than among women with COVID-19, he said in an interview.

There are a lot of androgen blocker candidates, but he said spironolactone – a mainstay of acne treatment – might well be the best for the pandemic because of its concomitant lung and heart benefits.

The message counters a post on Instagram in March from a New York City dermatologist in private practice, Ellen Marmur, MD, that raised a question about spironolactone. Concerned about the situation in New York, she reviewed the literature and found a 2005 study that reported that macrophages drawn from 10 heart failure patients had increased ACE2 activity and increased messenger RNA expression after the subjects had been on spironolactone 25 mg per day for a month.

In an interview, Adam Friedman, MD, professor and interim chair of dermatology at George Washington University, Washington, said he’s been addressing concerns about spironolactone in educational webinars because of it.

He tells his audience that “you can’t make any claims” for COVID-19 based on the 2005 study. It was a small clinical study in heart failure patients and only assessed ACE2 expression on macrophages, not respiratory, cardiac, or mesangial cells, which are the relevant locations for viral invasion and damage. In fact, there are studies showing that spironolactone reduced ACE2 in renal mesangial cells. Also of note, spironolactone has been used with no indication of virus risk since the 1950s, he pointed out. The American Academy of Dermatology has not said to stop spironolactone.

The explanation for the impressive clinical benefits of sacubitril/valsartan in women with heart failure with preserved ejection fraction in the PARAGON-HF trial – but not in the men – remains elusive, Jonathan W. Cunningham, MD, said at the joint scientific sessions of the American College of Cardiology and the World Heart Federation. The meeting was conducted online after its cancellation because of the COVID-19 pandemic.

“We’ve all been trying to unravel the explanation for the differential effects between men and women in the primary trial. I don’t know that this NT-proBNP substudy gives a clear answer because we did see similar reduction in NT-proBNP in the men and women,” said Dr. Cunningham of Brigham and Women’s Hospital, Boston.

“Unfortunately, I think we’re still looking for the underlying physiological explanation for that very interesting interaction,” he added.

The PARAGON-HF trial included 4,796 patients with heart failure with preserved ejection fraction (HFpEF) who were randomized double-blind to sacubitril/valsartan (Entresto) or valsartan on top of background guideline-directed medical therapy and followed for a median of 34 months (N Engl J Med. 2019 Oct 24;381[17]:1609-20). The sacubitril/valsartan group’s 13% relative risk reduction in the primary composite endpoint of cardiovascular death and total heart failure hospitalizations fell tantalizingly short of statistical significance (P = 0.058).

In women, however, who comprised more than half of the study population, the benefit of sacubitril/valsartan was larger: a 27% relative risk reduction compared to valsartan alone. That’s a statistically significant difference in a prespecified subgroup analysis, but according to the rules of clinical trials and statistics it must be considered hypothesis-generating and nondefinitive, since the overall trial was negative. Men randomized to sacubitril/valsartan had a modest 3% increased risk of the primary endpoint compared to men on valsartan.

Because of the enormous unmet need for effective therapy for HFpEF, and the fact that HFpEF is more common in women than men, the search is on for an explanation that would account for the striking gender difference in outcome in PARAGON-HF. At ACC 2020, Dr. Cunningham presented a secondary analysis of the trial focusing on the relationships between baseline and on-treatment N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and clinical outcomes.

Among the key findings was that the higher the baseline NT-proBNP, the greater the likelihood of the primary endpoint. Also, sacubitril/valsartan reduced NT-proBNP to a similar extent in men and women: For example, by 20% compared to valsartan in men and by 18% in women when measured 16 weeks after randomization. And reduction in NT-proBNP was associated with reduced risk of cardiovascular death and heart failure hospitalizations; indeed, 60% of participants in PARAGON-HF experienced a decrease in NT-proBNP, and they had a 23% lower event rate compared to patients whose NT-proBNP increased during the course of the study.

Another intriguing finding in the parent PARAGON-HF trial was that HFpEF patients with an LVEF of 45%-57% had a 22% lower rate of the primary endpoint than those with an LVEF of 58% or more. But as with the gender difference in clinical outcomes in response to sacubitril/valsartan, the difference in outcomes based on ejection fraction was not mediated by the drug’s impact on NT-proBNP, since sacubitril/valsartan reduced NT-proBNP to a similar degree in HFpEF patients with an LVEF above or below 57%.

The difference in outcomes by ejection fraction wasn’t entirely surprising, because those low-normal–range ejection fractions where sacubitril/valsartan had a favorable impact approach those characteristic of heart failure with reduced ejection fraction (HFrEF), and guidelines give sacubitril/valsartan a class I recommendation in patients with HFrEF on the strength of the medication’s demonstrated reduction in morbidity and mortality in the PARADIGM-HF trial.

Discussant Lee R. Goldberg, MD, predicted this analysis will have an impact on the design of future clinical trials in HFpEF, which up until now have required certain minimum NT-proBNP levels for participation.

“Maybe this is why so many of our trials in HFpEF have been unsuccessful. It’s a very heterogeneous population and perhaps NT-proBNP cutoffs are leading to a lot of mischief or heterogeneity that causes us some difficulty,” said Dr. Goldberg, professor of medicine and chief of the section of advanced heart failure and cardiac transplantation at the University of Pennsylvania, Philadelphia.

Dr. Cunningham reported having no financial conflicts regarding his study. The PARAGON-HF trial was funded by Novartis.

Simultaneously with Dr. Cunningham’s presentation at ACC 2020, the study results were published online (JACC Heart Fail. 2020 Mar 26; doi: 10.1016/j.jchf.2020.03.002.

The explanation for the impressive clinical benefits of sacubitril/valsartan in women with heart failure with preserved ejection fraction in the PARAGON-HF trial – but not in the men – remains elusive, Jonathan W. Cunningham, MD, said at the joint scientific sessions of the American College of Cardiology and the World Heart Federation. The meeting was conducted online after its cancellation because of the COVID-19 pandemic.

“We’ve all been trying to unravel the explanation for the differential effects between men and women in the primary trial. I don’t know that this NT-proBNP substudy gives a clear answer because we did see similar reduction in NT-proBNP in the men and women,” said Dr. Cunningham of Brigham and Women’s Hospital, Boston.

“Unfortunately, I think we’re still looking for the underlying physiological explanation for that very interesting interaction,” he added.

The PARAGON-HF trial included 4,796 patients with heart failure with preserved ejection fraction (HFpEF) who were randomized double-blind to sacubitril/valsartan (Entresto) or valsartan on top of background guideline-directed medical therapy and followed for a median of 34 months (N Engl J Med. 2019 Oct 24;381[17]:1609-20). The sacubitril/valsartan group’s 13% relative risk reduction in the primary composite endpoint of cardiovascular death and total heart failure hospitalizations fell tantalizingly short of statistical significance (P = 0.058).

In women, however, who comprised more than half of the study population, the benefit of sacubitril/valsartan was larger: a 27% relative risk reduction compared to valsartan alone. That’s a statistically significant difference in a prespecified subgroup analysis, but according to the rules of clinical trials and statistics it must be considered hypothesis-generating and nondefinitive, since the overall trial was negative. Men randomized to sacubitril/valsartan had a modest 3% increased risk of the primary endpoint compared to men on valsartan.

Because of the enormous unmet need for effective therapy for HFpEF, and the fact that HFpEF is more common in women than men, the search is on for an explanation that would account for the striking gender difference in outcome in PARAGON-HF. At ACC 2020, Dr. Cunningham presented a secondary analysis of the trial focusing on the relationships between baseline and on-treatment N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and clinical outcomes.

Among the key findings was that the higher the baseline NT-proBNP, the greater the likelihood of the primary endpoint. Also, sacubitril/valsartan reduced NT-proBNP to a similar extent in men and women: For example, by 20% compared to valsartan in men and by 18% in women when measured 16 weeks after randomization. And reduction in NT-proBNP was associated with reduced risk of cardiovascular death and heart failure hospitalizations; indeed, 60% of participants in PARAGON-HF experienced a decrease in NT-proBNP, and they had a 23% lower event rate compared to patients whose NT-proBNP increased during the course of the study.

Patients with stable coronary artery disease and type 2 diabetes mellitus could benefit from a “plethora of newly available risk-reduction strategies,” but their “adoption into clinical practice has been slow” and inconsistent, prompting an expert panel organized by the American Heart Association to collate the range of treatment recommendations now applicable to this patient population in a scientific statement released on April 13.

“There are a number of things to consider when treating patients with stable coronary artery disease [CAD] and type 2 diabetes mellitus [T2DM], with new medications and trials and data emerging. It’s difficult to keep up with all of the complexities,” which was why the Association’s Councils on Lifestyle and Cardiometabolic Health and on Clinical Cardiology put together a writing group to summarize and prioritize the range of lifestyle, medical, and interventional options that now require consideration and potential use on patients managed in routine practice, explained Suzanne V. Arnold, MD, chair of the writing group, in an interview.

The new scientific statement (Circulation. 2020 Apr 13; doi: 10.1161/CIR.0000000000000766), aimed primarily at cardiologists but also intended to inform primary care physicians, endocrinologists, and all other clinicians who deal with these patients, pulls together “everything someone needs to think about if they care for patients with CAD and T2DM,” said Deepak L. Bhatt, MD, professor of medicine at Harvard Medical School in Boston and vice chair of the statement-writing panel in an interview. “There is a lot to know,” he added.

The statement covers antithrombotic therapies; blood pressure control, with a discussion of both the appropriate pressure goal and the best drug types used to reach it; lipid management; glycemic control; lifestyle modification; weight management, including the role of bariatric surgery; and approaches to managing stable angina, both medically and with revascularization.

“The goal was to give clinicians a good sense of what new treatments they should consider” for these patients, said Dr. Bhatt, who is also director of interventional cardiovascular programs at Brigham and Women’s Hospital, also in Boston. Because of the tight associations between T2DM and cardiovascular disease in general including CAD, “cardiologists are increasingly involved in managing patients with T2DM,” he noted. The statement gives a comprehensive overview and critical assessment of the management of these patients as of the end of 2019 as a consensus from a panel of 11 experts .

The statement also stressed that “substantial portions of patients with T2DM and CAD, including those after an acute coronary syndrome, do not receive therapies with proven cardiovascular benefit, such as high-intensity statins, dual-antiplatelet therapy, angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, and glucose-lowering agents with proven cardiovascular benefits.

“These gaps in care highlight a critical opportunity for cardiovascular specialists to assume a more active role in the collaborative care of patients with T2DM and CAD,” the statement said. This includes “encouraging cardiologists to become more active in the selection of glucose-lowering medications” for these patients because it could “really move the needle,” said Dr. Arnold, a cardiologist with Saint Luke’s Health System in Kansas City, Mo. She was referring specifically to broader reliance on both the SGTL2 (sodium-glucose cotransporter 2) inhibitors and the GLP-1 (glucagonlike peptide-1) receptor agonists as top choices for controlling hyperglycemia. Based on recent evidence drugs in these two classes “could be considered first line for patients with T2DM and CAD, and would likely be preferred over metformin,” Dr. Arnold said in an interview. Although the statement identified the SGLT2 inhibitors as “the first drug class [for glycemic control] to show clear benefits on cardiovascular outcomes,” it does not explicitly label the class first-line and it also skirts that designation for the GLP-1 receptor agonist class, while noting that metformin “remains the drug most frequently recommended as first-line therapy in treatment guidelines.”

“I wouldn’t disagree with someone who said that SGLT2 inhibitors and GLP-1 receptor agonists are first line,” but prescribing patterns also depend on familiarity, cost, and access, noted Dr. Bhatt, which can all be issues with agents from these classes compared with metformin, a widely available generic with decades of use. “Metformin is safe and cheap, so we did not want to discount it,” said Dr. Arnold. Dr. Bhatt recently coauthored an editorial that gave an enthusiastic endorsement to using SGLT2 inhibitors in patients with diabetes (Cell Metab. 2019 Nov 5;30[5]:47-9).

Another notable feature of the statement is the potential it assigns to bariatric surgery as a management tool with documented safety and efficacy for improving cardiovascular risk factors. However, the statement also notes that randomized trials “have thus far been inadequately powered to assess cardiovascular events and mortality, although observational studies have consistently shown cardiovascular risk reduction with such procedures.” The statement continues that despite potential cardiovascular benefits “bariatric surgery remains underused among eligible patients,” and said that surgery performed as Roux-en-Y bypass or sleeve gastrectomy “may be another effective tool for cardiovascular risk reduction in the subset of patients with obesity,” particularly patients with a body mass index of at least 35 kg/m².

“While the percentage of patients who are optimal for bariatric surgery is not known, the most recent NHANES [National Health and Nutrition Examination Study] study showed that less than 0.5% of eligible patients underwent bariatric surgery,” Dr. Arnold noted. Bariatric surgery is “certainly not a recommendation for everyone, or even a majority of patients, but bariatric surgery should be on our radar,” for patients with CAD and T2DM, she said.

Right now, “few cardiologists think about bariatric surgery,” as a treatment option, but study results have shown that “in carefully selected patients treated by skilled surgeons at high-volume centers, patients will do better with bariatric surgery than with best medical therapy for improvements in multiple risk factors, including glycemic control,” Dr. Bhatt said in the interview. “It’s not first-line treatment, but it’s an option to consider,” he added, while also noting that bariatric surgery is most beneficial to patients relatively early in the course of T2DM, when its been in place for just a few years rather than a couple of decades.

The statement also notably included a “first-line” call out for icosapent ethyl (Vascepa), a novel agent approved in December 2019 for routine use in U.S. patients, including those with CAD and T2DM as long as their blood triglyceride level was at least 150 mg/dL. Dr. Bhatt, who led the REDUCE-IT study that was pivotal for proving the safety and efficacy of icosapent ethyl (N Engl J Med. 2019 Jan 3;380[1]:11-22), estimated that anywhere from 15% to as many as half the patients with CAD and T2DM might have a triglyceride level that would allow them to receive icosapent ethyl. One population-based study in Canada of nearly 200,000 people with atherosclerotic cardiovascular disease found a 25% prevalence of the triglyceride level needed to qualify to receive icosapent ethyl under current labeling, he noted (Eur Heart J. 2020 Jan 1;41[1]:86-94). However, the FDA label does not specify that triglycerides be measured when fasting, and a nonfasting level of about 150 mg/dL will likely appear for patients with fasting levels that fall as low as about 100 mg/dL, Dr. Bhatt said. He hoped that future studies will assess the efficacy of icosapent ethyl in patients with even lower triglyceride levels.

Other sections of the statement also recommend that clinicians: Target long-term dual-antiplatelet therapy to CAD and T2DM patients with additional high-risk markers such as prior MI, younger age, and tobacco use; prescribe a low-dose oral anticoagulant along with an antiplatelet drug such as aspirin for secondary-prevention patients; promote a blood pressure target of less than 140/90 mm Hg for all CAD and T2DM patients and apply a goal of less than 130/80 mm Hg in higher-risk patients such as blacks, Asians, and those with cerebrovascular disease; and reassure patients that “despite a modest increase in blood sugars, the risk-benefit ratio is clearly in favor of administering statins to people with T2DM and CAD.”

Dr. Arnold had no disclosures. Dr. Bhatt has been an adviser to Cardax, Cereno Scientific, Medscape Cardiology, PhaseBio; PLx Pharma, and Regado Biosciences, and he has received research funding from numerous companies including Amarin, the company that markets icosapent ethyl.

Right now, “few cardiologists think about bariatric surgery,” as a treatment option, but study results have shown that “in carefully selected patients treated by skilled surgeons at high-volume centers, patients will do better with bariatric surgery than with best medical therapy for improvements in multiple risk factors, including glycemic control,” Dr. Bhatt said in the interview. “It’s not first-line treatment, but it’s an option to consider,” he added, while also noting that bariatric surgery is most beneficial to patients relatively early in the course of T2DM, when its been in place for just a few years rather than a couple of decades.

The statement also notably included a “first-line” call out for icosapent ethyl (Vascepa), a novel agent approved in December 2019 for routine use in U.S. patients, including those with CAD and T2DM as long as their blood triglyceride level was at least 150 mg/dL. Dr. Bhatt, who led the REDUCE-IT study that was pivotal for proving the safety and efficacy of icosapent ethyl (N Engl J Med. 2019 Jan 3;380[1]:11-22), estimated that anywhere from 15% to as many as half the patients with CAD and T2DM might have a triglyceride level that would allow them to receive icosapent ethyl. One population-based study in Canada of nearly 200,000 people with atherosclerotic cardiovascular disease found a 25% prevalence of the triglyceride level needed to qualify to receive icosapent ethyl under current labeling, he noted (Eur Heart J. 2020 Jan 1;41[1]:86-94). However, the FDA label does not specify that triglycerides be measured when fasting, and a nonfasting level of about 150 mg/dL will likely appear for patients with fasting levels that fall as low as about 100 mg/dL, Dr. Bhatt said. He hoped that future studies will assess the efficacy of icosapent ethyl in patients with even lower triglyceride levels.

Other sections of the statement also recommend that clinicians: Target long-term dual-antiplatelet therapy to CAD and T2DM patients with additional high-risk markers such as prior MI, younger age, and tobacco use; prescribe a low-dose oral anticoagulant along with an antiplatelet drug such as aspirin for secondary-prevention patients; promote a blood pressure target of less than 140/90 mm Hg for all CAD and T2DM patients and apply a goal of less than 130/80 mm Hg in higher-risk patients such as blacks, Asians, and those with cerebrovascular disease; and reassure patients that “despite a modest increase in blood sugars, the risk-benefit ratio is clearly in favor of administering statins to people with T2DM and CAD.”

Dr. Arnold had no disclosures. Dr. Bhatt has been an adviser to Cardax, Cereno Scientific, Medscape Cardiology, PhaseBio; PLx Pharma, and Regado Biosciences, and he has received research funding from numerous companies including Amarin, the company that markets icosapent ethyl.

It’s becoming clear that COVID-19 infection can involve the cardiovascular system in many different ways, and this has “evolving” potential implications for treatment, say a team of cardiologists on the frontlines of the COVID-19 battle in New York City.

In an article published online April 3 in Circulation, Justin Fried, MD, Division of Cardiology, Columbia University, New York City, and colleagues present four case studies of COVID-19 patients with various cardiovascular presentations.

Case 1 is a 64-year-old woman whose predominant symptoms on admission were cardiac in nature, including chest pain and ST elevation, but without fever, cough, or other symptoms suggestive of COVID-19.

“In patients presenting with what appears to be a typical cardiac syndrome, COVID-19 infection should be in the differential during the current pandemic, even in the absence of fever or cough,” the clinicians advise.

Case 2 is a 38-year-old man with cardiogenic shock and acute respiratory distress with profound hypoxia who was rescued with veno-arterial-venous extracorporeal membrane oxygenation (VV ECMO).

The initial presentation of this patient was more characteristic of severe COVID-19 disease, and cardiac involvement only became apparent after the initiation of ECMO, Fried and colleagues report.

Based on this case, they advise a “low threshold” to assess for cardiogenic shock in patients with acute systolic heart failure related to COVID-19. If inotropic support fails in these patients, intra-aortic balloon pump should be considered first for mechanical circulatory support because it requires the least maintenance from medical support staff.

In addition, in their experience, when a patient on VV ECMO develops superimposed cardiogenic shock, adding an arterial conduit at a relatively low blood flow rate may provide the necessary circulatory support without inducing left ventricular distension, they note.

“Our experience confirms that rescue of patients even with profound cardiogenic or mixed shock may be possible with temporary hemodynamic support at centers with availability of such devices,” Fried and colleagues report.

Case 3 is a 64-year-old woman with underlying cardiac disease who developed profound decompensation with COVID-19 infection.

This case demonstrates that the infection can cause decompensation of underlying heart failure and may lead to mixed shock, the clinicians say.

“Invasive hemodynamic monitoring, if feasible, may be helpful to manage the cardiac component of shock in such cases. Medications that prolong the QT interval are being considered for COVID-19 patients and may require closer monitoring in patients with underlying structural heart disease,” they note.

Case 4 is a 51-year-old man who underwent a heart transplant in 2007 and a kidney transplant in 2010. He had COVID-19 symptoms akin to those seen in nonimmunosuppressed patients with COVID-19.

The COVID-19 pandemic presents a “unique challenge” for solid organ transplant recipients, with only “limited” data on how to adjust immunosuppression during COVID-19 infection, Fried and colleagues say.

The pandemic also creates a challenge for the management of heart failure patients on the heart transplant wait list; the risks of delaying a transplant need to be balanced against the risks of donor infection and uncertainty regarding the impact of post-transplant immunosuppression protocols, they note.

As reported by Medscape Medical News, the American Heart Association has developed a COVID-19 patient registry to collect data on cardiovascular conditions and outcomes related to COVID-19 infection.

AstraZeneca has announced that the phase 3 DAPA-CKD trial for dapagliflozin (Farxiga) in patients with chronic kidney disease has been halted early because of overwhelming efficacy of the drug, at the recommendation of an independent data monitoring committee.

DAPA-CKD is an international, multicenter, randomized, double-blinded trial in 4,245 patients with stage 2-4 chronic kidney disease. Patients received either 10 mg of the dapagliflozin once-daily or a placebo. The primary composite endpoint is worsening of renal function, defined as a composite of an estimated glomerular filtration rate decline of at least 50%, onset of end-stage kidney disease, and death from cardiovascular or renal cause.

The decision to stop the trial came after a routine assessment of efficacy and safety that showed dapagliflozin’s benefits significantly earlier than expected. AstraZeneca will initiate closure of the study, and results will be published and submitted for presentation at a forthcoming medical meeting.

Dapagliflozin is a sodium-glucose transporter 2 inhibitor currently indicated for the treatment type 2 diabetes patients with inadequately controlled type 2 diabetes and for reduction of the risk of hospitalization for heart failure. In August 2019, the drug was granted Fast Track status by the Food and Drug Administration for the treatment of chronic kidney disease. In January 2020, the agency also granted Fast Track status for the reduction of risk of cardiovascular death or worsening of heart failure in adult patients, regardless of diabetes status, with heart failure with reduced ejection fraction.

“Chronic kidney disease patients have limited treatment options, particularly those without type-2 diabetes. We are very pleased the data monitoring committee concluded that patients experienced overwhelming benefit. Farxiga has the potential to change the management of chronic kidney disease for patients around the world,” Mene Pangalos, executive vice president of BioPharmaceuticals R&D, said in the press release.

Not too many years ago, clinicians who treat patients with heart failure, especially those at high risk for decompensation, lamented what seemed a dearth of new drug therapy options.

Now, with the toolbox brimming with new guideline-supported alternatives, a novel investigational agent—one with a mechanism unlike that of any approved heart failure drug—has turned in positive results in a large randomized, placebo-controlled trial.

Importantly, it entered an especially high-risk population with heart failure and reduced ejection fraction (HFrEF); everyone in the trial had experienced a prior, usually quite recent, heart failure exacerbation.

In such patients, the addition of vericiguat (Merck/Bayer) to standard drug and device therapies was followed by a moderately but significantly reduced relative risk for the trial’s primary clinical endpoint over about 11 months.

Recipients benefited with a 10% drop in adjusted risk (P = .019) for cardiovascular (CV) death or first heart failure hospitalization compared to a placebo control group.

But researchers leading the 5050-patient Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction (VICTORIA), as well as unaffiliated experts who have studied the trial, say that in this case, risk reduction in absolute numbers is a more telling outcome.

“Remember who we’re talking about here in terms of the patients who have this degree of morbidity and mortality,” VICTORIA study chair Paul W. Armstrong, MD, University of Alberta, Edmonton, Canada, told theheart.org | Medscape Cardiology, pointing to the “incredible placebo-group event rate and relatively modest follow-up of 10.8 months.”

The control group’s primary-endpoint event rate was 37.8 per 100 patient-years, 4.2 points higher than the rate for patients who received vericiguat. “And from there you get a number needed to treat of 24 to prevent one event, which is low,” Armstrong said.

“Think about the hundreds of thousands of people with this disease and what that means at the public health level.” About one in four patients with heart failure experience such exacerbations each year, he said.

Armstrong is lead author on the 42-country trial’s publication today in the New England Journal of Medicine, timed to coincide with his online presentation for the American College of Cardiology 2020 Scientific Session (ACC.20)/World Congress of Cardiology (WCC). The annual session was conducted virtually this year following the traditional live meeting’s cancelation due to the COVID-19 pandemic.

The VICTORIA presentation and publication flesh out the cursory top-line primary results that Merck unveiled in November 2019, which had not included the magnitude of the vericiguat relative benefit for the primary endpoint.

The trial represents “another win” for the treatment of heart failure, Clyde W. Yancy, MD, Northwestern University, Chicago, Illinois, said as an invited discussant following Armstrong’s presentation.

“Hospitalization for heart failure generates a major inflection point in the natural history of this condition, with a marked change in the risk for re-hospitalization and death. Up until now, no prior therapies have attenuated this risk, except for more intensive processes and care improvement strategies,” he said.

“Now we have a therapy that may be the first one to change that natural history after a person with heart failure has had a worsening event.”

Interestingly, the primary-endpoint reduction was driven by a significant drop in heart failure hospitalizations, even within a fairly short follow-up time.

“What was fascinating is that the requisite number of events were accrued in less than 12 months — meaning that inexplicably, this is one of the few times we’ve had a trial where the event rate realized was higher than the event rate predicted,” Yancy observed for theheart.org | Medscape Cardiology.

Although the effect size was similar to what was observed for dapagliflozin (Farxiga, AstraZeneca) in DAPA-HF and sacubitril/valsartan (Entresto, Novartis) in PARADIGM-HF, he said, VICTORIA’s population was much sicker and had an “astonishingly high” event rate even while receiving aggressive background heart failure therapy.

It included “triple therapy with renin-angiotensin system inhibitors, β-blockers, and mineralocorticoid receptor antagonists in 60% of patients, and at least double therapy in 90% of patients.” Also, Yancy said, 30% of the population had implantable devices, such as defibrillators and biventricular pacemakers.

Such patients with advanced, late-stage disease are common as the latest therapies for heart failure prolong their survival, notes Lynne W. Stevenson, MD, Vanderbilt University, Nashville, Tennessee, also as an invited discussant after Armstrong’s presentation.

“It’s a unique population with longer disease duration, more severe disease, and narrow options,” one in which personalized approaches are needed. Yet VICTORIA-like patients “have been actively excluded from all the trials that have shown benefit,” she said.

“VICTORIA finally addresses this population of decompensated patients,” she said, and seems to show that vericiguat may help some of them.

At the University of Glasgow, United Kingdom, John J.V. McMurray, MBChB, MD, agreed that the relative risk reduction was “small but significant,” but also that the control group’s event rate was “very high, reflecting the inclusion and exclusion criteria.”

As a result, McMurray told theheart.org | Medscape Cardiology, there was “quite a large absolute risk reduction and small number needed to treat. Also on the positive side: no significant excess of the adverse effects we might have been concerned about,” for example, hypotension.

Vericiguat, if ultimately approved in heart failure, “isn’t going to be first-line or widely used, but it is an additional asset,” he said. “Anything that helps in heart failure is valuable. There are always patients who can’t tolerate treatments, and always people who need more done.”

It’s appealing that the drug works by a long but unfruitfully explored mechanism that has little to do directly with the renin-angiotensin-aldosterone system.

Vericiguat is a soluble guanylate cyclase stimulator that boosts cyclic guanosine monophosphate activity along several pathways, potentiating the salutary pulmonary artery–vasodilating effects of nitric oxide. It improved natriuretic peptide levels in the preceding phase 2 SOCRATES-REDUCED study.

“This is not a me-too drug. It’s a new avenue for heart failure patients,” Armstrong said in an interview. It’s taken once daily, “was relatively easy to titrate up to the target dose, pretty well tolerated, and very safe. And remarkably, you don’t need to measure renal function.”

However, because the drug’s mechanism resides in the same neighborhood of biochemical pathways affected by chronic nitrates and by phosphodiesterase type 5 inhibitors, such as sildenafil and tadalafil, patients taking those drugs were excluded from VICTORIA. Acute nitrates were allowed, however.

Symptomatic hypotension occurred in less than 10% and syncope in 4% or less of both groups; neither difference between the two groups was significant. Anemia developed more often in patients receiving vericiguat (7.6%) than in the control group (5.7%).

“We think that on balance, vericiguat is a useful alternative option for patients. But certainly the only thing we can say at this point is it works in the high-risk population that we studied,” Armstrong said. “Whether it works in lower-risk populations and how it compares is speculation, of course.”

The drug’s cost, whatever it might be if approved, is another factor affecting how it would be used, noted several observers.

“We don’t know what the cost-effectiveness will be. It should be reasonable because the benefit was on hospitalization. That’s a costly outcome,” Yancy said.

McMurray was also hopeful. “If the treatment is well tolerated and reasonably priced, it may still be a valuable asset for at least a subset of patients.”

VICTORIA was supported by Merck Sharp & Dohme Corp and Bayer AG. Armstrong discloses receiving research grants from Merck, Bayer AG, Sanofi-Aventis, Boehringer Ingelheim, and CSL Ltd and consulting fees from Merck, Bayer AG, AstraZeneca, and Novartis. Y ancy has previously disclosed no relevant financial relationships. Stevenson has previously disclosed receiving research grants from Novartis, consulting or serving on an advisory board for Abbott and travel expenses or meals from Novartis and St Jude Medical.

However, because the drug’s mechanism resides in the same neighborhood of biochemical pathways affected by chronic nitrates and by phosphodiesterase type 5 inhibitors, such as sildenafil and tadalafil, patients taking those drugs were excluded from VICTORIA. Acute nitrates were allowed, however.

Symptomatic hypotension occurred in less than 10% and syncope in 4% or less of both groups; neither difference between the two groups was significant. Anemia developed more often in patients receiving vericiguat (7.6%) than in the control group (5.7%).

“We think that on balance, vericiguat is a useful alternative option for patients. But certainly the only thing we can say at this point is it works in the high-risk population that we studied,” Armstrong said. “Whether it works in lower-risk populations and how it compares is speculation, of course.”

The drug’s cost, whatever it might be if approved, is another factor affecting how it would be used, noted several observers.

“We don’t know what the cost-effectiveness will be. It should be reasonable because the benefit was on hospitalization. That’s a costly outcome,” Yancy said.

McMurray was also hopeful. “If the treatment is well tolerated and reasonably priced, it may still be a valuable asset for at least a subset of patients.”

Not too many years ago, clinicians who treat patients with heart failure, especially those at high risk for decompensation, lamented what seemed a dearth of new drug therapy options.

Now, with the toolbox brimming with new guideline-supported alternatives, a novel investigational agent—one with a mechanism unlike that of any approved heart failure drug—has turned in positive results in a large randomized, placebo-controlled trial.

Importantly, it entered an especially high-risk population with heart failure and reduced ejection fraction (HFrEF); everyone in the trial had experienced a prior, usually quite recent, heart failure exacerbation.

In such patients, the addition of vericiguat (Merck/Bayer) to standard drug and device therapies was followed by a moderately but significantly reduced relative risk for the trial’s primary clinical endpoint over about 11 months.

Recipients benefited with a 10% drop in adjusted risk (P = .019) for cardiovascular (CV) death or first heart failure hospitalization compared to a placebo control group.

But researchers leading the 5050-patient Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction (VICTORIA), as well as unaffiliated experts who have studied the trial, say that in this case, risk reduction in absolute numbers is a more telling outcome.

“Remember who we’re talking about here in terms of the patients who have this degree of morbidity and mortality,” VICTORIA study chair Paul W. Armstrong, MD, University of Alberta, Edmonton, Canada, told theheart.org | Medscape Cardiology, pointing to the “incredible placebo-group event rate and relatively modest follow-up of 10.8 months.”

The control group’s primary-endpoint event rate was 37.8 per 100 patient-years, 4.2 points higher than the rate for patients who received vericiguat. “And from there you get a number needed to treat of 24 to prevent one event, which is low,” Armstrong said.

“Think about the hundreds of thousands of people with this disease and what that means at the public health level.” About one in four patients with heart failure experience such exacerbations each year, he said.

Armstrong is lead author on the 42-country trial’s publication today in the New England Journal of Medicine, timed to coincide with his online presentation for the American College of Cardiology 2020 Scientific Session (ACC.20)/World Congress of Cardiology (WCC). The annual session was conducted virtually this year following the traditional live meeting’s cancelation due to the COVID-19 pandemic.

The VICTORIA presentation and publication flesh out the cursory top-line primary results that Merck unveiled in November 2019, which had not included the magnitude of the vericiguat relative benefit for the primary endpoint.

The trial represents “another win” for the treatment of heart failure, Clyde W. Yancy, MD, Northwestern University, Chicago, Illinois, said as an invited discussant following Armstrong’s presentation.

“Hospitalization for heart failure generates a major inflection point in the natural history of this condition, with a marked change in the risk for re-hospitalization and death. Up until now, no prior therapies have attenuated this risk, except for more intensive processes and care improvement strategies,” he said.

“Now we have a therapy that may be the first one to change that natural history after a person with heart failure has had a worsening event.”

Interestingly, the primary-endpoint reduction was driven by a significant drop in heart failure hospitalizations, even within a fairly short follow-up time.

“What was fascinating is that the requisite number of events were accrued in less than 12 months — meaning that inexplicably, this is one of the few times we’ve had a trial where the event rate realized was higher than the event rate predicted,” Yancy observed for theheart.org | Medscape Cardiology.

Although the effect size was similar to what was observed for dapagliflozin (Farxiga, AstraZeneca) in DAPA-HF and sacubitril/valsartan (Entresto, Novartis) in PARADIGM-HF, he said, VICTORIA’s population was much sicker and had an “astonishingly high” event rate even while receiving aggressive background heart failure therapy.

It included “triple therapy with renin-angiotensin system inhibitors, β-blockers, and mineralocorticoid receptor antagonists in 60% of patients, and at least double therapy in 90% of patients.” Also, Yancy said, 30% of the population had implantable devices, such as defibrillators and biventricular pacemakers.

Such patients with advanced, late-stage disease are common as the latest therapies for heart failure prolong their survival, notes Lynne W. Stevenson, MD, Vanderbilt University, Nashville, Tennessee, also as an invited discussant after Armstrong’s presentation.

“It’s a unique population with longer disease duration, more severe disease, and narrow options,” one in which personalized approaches are needed. Yet VICTORIA-like patients “have been actively excluded from all the trials that have shown benefit,” she said.

“VICTORIA finally addresses this population of decompensated patients,” she said, and seems to show that vericiguat may help some of them.

At the University of Glasgow, United Kingdom, John J.V. McMurray, MBChB, MD, agreed that the relative risk reduction was “small but significant,” but also that the control group’s event rate was “very high, reflecting the inclusion and exclusion criteria.”

As a result, McMurray told theheart.org | Medscape Cardiology, there was “quite a large absolute risk reduction and small number needed to treat. Also on the positive side: no significant excess of the adverse effects we might have been concerned about,” for example, hypotension.

Vericiguat, if ultimately approved in heart failure, “isn’t going to be first-line or widely used, but it is an additional asset,” he said. “Anything that helps in heart failure is valuable. There are always patients who can’t tolerate treatments, and always people who need more done.”

It’s appealing that the drug works by a long but unfruitfully explored mechanism that has little to do directly with the renin-angiotensin-aldosterone system.

Vericiguat is a soluble guanylate cyclase stimulator that boosts cyclic guanosine monophosphate activity along several pathways, potentiating the salutary pulmonary artery–vasodilating effects of nitric oxide. It improved natriuretic peptide levels in the preceding phase 2 SOCRATES-REDUCED study.

“This is not a me-too drug. It’s a new avenue for heart failure patients,” Armstrong said in an interview. It’s taken once daily, “was relatively easy to titrate up to the target dose, pretty well tolerated, and very safe. And remarkably, you don’t need to measure renal function.”

However, because the drug’s mechanism resides in the same neighborhood of biochemical pathways affected by chronic nitrates and by phosphodiesterase type 5 inhibitors, such as sildenafil and tadalafil, patients taking those drugs were excluded from VICTORIA. Acute nitrates were allowed, however.

“We don’t know what the cost-effectiveness will be. It should be reasonable because the benefit was on hospitalization. That’s a costly outcome,” Yancy said.

McMurray was also hopeful. “If the treatment is well tolerated and reasonably priced, it may still be a valuable asset for at least a subset of patients.”
