FDA pulls amputation boxed warning off canagliflozin label
The Food and Drug Administration has removed the boxed warning about the risk of leg and foot amputations for canagliflozin (Invokana, Invokamet, Janssen), a sodium-glucose cotransporter-2 (SGLT2) inhibitor for the treatment of type 2 diabetes, the agency announced Aug. 26.
As previously reported by Medscape Medical News, the FDA added the boxed warning to the canagliflozin label in May 2017, after an approximately doubled risk for lower-extremity amputations with the drug compared with placebo was seen during two trials.
The FDA said the decision to remove the boxed warning was made following a review of new data from three clinical trials, which demonstrated additional heart- and kidney-related benefits and led to additional approved uses for canagliflozin.
In 2018, canagliflozin was approved to reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes who have established cardiovascular disease.
In 2019, canagliflozin was approved to reduce the risk of end-stage kidney disease, worsening of kidney function, cardiovascular death, and heart failure hospitalization, in adults with type 2 diabetes and diabetic kidney disease.
“Collectively, these newly identified effects of canagliflozin on heart and kidney disease show significantly enhanced benefit of this medicine,” the FDA said.
The safety information from these trials, the FDA said, suggests that the risk of amputation, “while still increased with canagliflozin, is lower than previously described, particularly when appropriately monitored.”
The agency added: “Based upon these considerations, FDA concluded that the boxed warning should be removed.”
The FDA announcement said clinicians and patients should continue to be aware of the importance of preventive foot care and to monitor for new pain, tenderness, sores, ulcers, and infections in the legs and feet. Risk factors that may predispose patients to amputation should be considered when choosing antidiabetic medicines.
Health care professionals are encouraged to report adverse reactions with canagliflozin to the FDA’s MedWatch program.

ESC 2020 looks to make its mark in ‘new era’ of virtual meetings
The coronavirus may have quashed plans to socialize and stroll the canals of Amsterdam while at this year’s European Society of Cardiology (ESC) Congress, but organizers are promising a historic digital experience that will “once again, be a celebration of discovery and ground-breaking science.”
“My message — if I have to choose only one thing why ESC 2020 will be a historic event — is that the physician working at the Cleveland Clinic, who was planning to attend this year in Amsterdam, as well as the colleague in a bush hospital in Uganda, who would have never have dreamed to be part of the ESC Congress, both will have for the first time the same access at the same time to knowledge shared at the worldwide leading cardiovascular meeting,” Marco Roffi, MD, co-chair of the scientific program, told theheart.org | Medscape Cardiology.
Taking a page from the American College of Cardiology, which set the virtual bar early in the pandemic with its highly interactive ACC 2020, ESC is taking some 80 Hot Line, clinical practice guidelines, and special sessions live with question-and-answer interactions and panel discussions.
The latest COVID-19 research and four new guideline documents — including recommendations on atrial fibrillation (AF), non-ST-segment elevation acute coronary syndromes, sports cardiology and exercise in patients with cardiovascular disease, and adult congenital heart disease — will be featured at the ESC Congress 2020, scheduled for August 29 to September 1.
Presentations will be shorter and sessions more focused, but more than 500 scientific and educational sessions will be streamed in addition to more than 4000 abstracts available live or on demand as full presentations or e-posters, said Roffi, University Hospital of Geneva, Switzerland.
To pull off the virtual event, a digital studio in Amsterdam will host hundreds of key opinion leaders, and ESC employed more than 1000 satellite studios around the world to gather contributions from scientists and experts with the help of 70 behind-the-scenes experts.
Nevertheless, a “strategic decision” was made to provide free access to the event and its content for 30 days — a strategy that has attracted some 58,000 registrants thus far, up from a record 32,000 attendees at last year’s congress in Paris, Roffi said.
“Obviously, the income will not be the same as a physical congress, but we felt there was too much at stake to make a compromise,” he said. “We believe we are the leaders in cardiovascular meetings in the physical ones and we want to keep this position even in the new era. And we believe this is the beginning of a new era in whatever form will be.”
Hot Line Sessions 1-3, Saturday (14:00 CEST)
The Hot Line sessions will feature 13 clinical trials and kick off with EMPEROR-Reduced, which compared the sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) added to standard care in patients with heart failure with reduced ejection fraction (HFrEF), with and without diabetes.
Eli Lilly and Boehringer Ingelheim already announced the trial met its composite primary endpoint of reducing cardiovascular (CV) death or HF hospitalization risk but the details will be important given the SGLT2 inhibitors› rapid shift beyond diabetes to HF and chronic kidney disease (CKD).
Results presented at ESC 2019 from the landmark DAPA-HF trial led to the recent new indication for dapagliflozin (Farxiga, AstraZeneca) for HFrEF in the absence of diabetes. New data will be released in a Sunday Hot Line session looking at the SGLT2 inhibitor among diabetic and nondiabetic CKD patients in DAPA-CKD, which was halted early because of overwhelming efficacy.
As the indication evolved, the SGLT2 inhibitors became truly cardiovascular disease drugs, Roffi said, “so all the cardiologists will have to become familiar with these agents.”
Hot Line 2 will look at the oral cardiac myosin inhibitor mavacamten as an alternative to surgery or percutaneous interventions to treat obstructive hypertrophic cardiomyopathy (HCM). The first-in-class investigational agent is thought to reduce the hypercontractility characteristic of HCM by inhibiting excessive actin-myosin cross-bridges, and it showed promise in the recent phase 2 dose-finding MAVERICK HCM trial.
Investigators are expected to flesh out details from the 251-patient phase 3 EXPLORER-HCM trial, which reported functional and symptomatic gains with once-daily dosing in top-line results released by developer MyoKardia.
“This is really a revolutionary way to treat — hopefully successfully — this very complex disease,” Roffi said.
Rounding out the day is the EAST-AFNET 4 trial, which has been almost 10 years in the making and examined whether early rhythm control with antiarrhythmic drugs and catheter ablation can prevent adverse outcomes in patients with AF compared with usual care alone based on the ESC 2010 AF treatment guidelines.
Hot Line Sessions 4-6, Sunday (14:00 CEST)
Hot Line 4 features the ATPCI study examining the addition of the oral antianginal agent trimetazidine to standard of care in 6007 patients with angina after recent successful percutaneous coronary intervention.
Next up is POPULAR-TAVI looking at aspirin with or without clopidogrel in patients undergoing transcatheter aortic valve implantation (TAVI).
“This is a dilemma that we have every day in the cath lab when we perform a TAVI because we have in front of us patients who, by definition, are at high bleeding risk, are old, and have comorbidities such as renal insufficiencies,” Roffi said. “I like this very much because it’s a very practical study. Whatever the response will be of this study, it will impact clinical practice.”
Hot Line 6 is devoted to the PARALLAX trial comparing sacubitril/valsartan (Entresto, Novartis) with individualized medical therapy in 2569 heart failure with preserved ejection fraction (HFpEF) patients. The primary outcomes are 12-week change in N-terminal pro-brain natriuretic peptide and 24-week change in 6-minute walk distance.
Hot Line Sessions 7-9, Monday (14:00 CEST)
The next day starts with the timely topic of inflammation with the LoDoCo2 trial, in which 5522 patients with stable coronary artery disease were randomized to low-dose colchicine 0.5 mg daily or placebo on top of optimal medical therapy. The primary composite endpoint is CV death, myocardial infarction (MI), ischemic stroke, and ischemia-driven revascularization.
Additional colchicine data also will be presented in a late-breaking science session on Saturday that includes the Australian COPS trial in acute coronary syndromes and new analyses from COLCOT, which demonstrated a 23% reduction in the risk of first ischemic CV events following an MI but no mortality benefit. The low-cost anti-inflammatory drug is also being tested in the mammoth 6000-patient phase 3 Colchicine Coronavirus SARS-CoV-2 (COLCORONA) trial, expected to be completed by the end of September.
Hot Line 8 switches gears with the open-label randomized HOME-PE trial comparing outpatient management of pulmonary embolism (PE) in 1975 select patients based on either the simplified Pulmonary Embolism Severity Index (PESI) score, featured in the most recent ESC acute PE guidelines, or the HESTIA criteria, developed in the HESTIA study. The event-driven primary end point is the composite of recurrent venous thromboembolism, major bleeding, and all-cause death at 30 days.
Last up on Monday is a new analysis on the effects of lowering blood pressure for prevention of CV events across various BP levels from the BPLTTC, which is the largest resource of patient-level randomized clinical trial data, at more than 350,000 patients.
Tuesday Hot Line Sessions 10-12 (14:00 CEST)
The final day of the Congress ends with bang, with the randomized BRACE-CORONA trial examining the effect of continuing or suspending angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) in 700 patients with SARS-CoV-2 infection.
Although several cardiovascular societies including ESC recommend continuation of renin-angiotensin-aldosterone system (RAAS) antagonists in COVID-19 patients, randomized data are lacking and patients have been rattled by early observations suggesting that ACE2 upregulation from RAAS antagonists could increase the risk of developing severe COVID-19.
“BRACE-CORONA will answer the question that everybody’s been asking, whether or not you should continue ARBs and ACE inhibitors in COVID-19 patients. This is a randomized trial and we are all very excited about it,” Roffi said.
COVID-19 will also be discussed in a late-breaking science session on Sunday and in three industry Q&A sessions scattered over the 4 days.
Rounding out the last Hot Line session is IMPACT-AFib, a claims database analysis of early vs delayed educational interventions to improve oral anticoagulation use in a whopping 80,000 patients with AF, and REALITY, a much-needed cost-effectiveness analysis of liberal vs restrictive transfusion strategies in 630 patients with acute MI and anemia.

First evidence of SARS-CoV-2 in heart cells
SARS-CoV-2 has been found in cardiac tissue of a child from Brazil with multisystem inflammatory syndrome (MIS-C) related to COVID-19 who presented with myocarditis and died of heart failure.
It’s believed to be the first evidence of direct infection of heart muscle cells by the virus; viral particles were identified in different cell lineages of the heart, including cardiomyocytes, endothelial cells, mesenchymal cells, and inflammatory cells.
The case was described in a report published online August 20 in The Lancet Child & Adolescent Health.
“The presence of the virus in various cell types of cardiac tissue, as evidenced by electron microscopy, shows that myocarditis in this case is likely a direct inflammatory response to the virus infection in the heart,” first author Marisa Dolhnikoff, MD, department of pathology, University of São Paulo, said in an interview.
There have been previous reports in adults with COVID-19 of both SARS-CoV-2 RNA by reverse transcription–polymerase chain reaction (RT-PCR) and viral particles by electron microscopy in cardiac tissue from endomyocardial specimens, the researchers noted. One of these reports, published in April by Tavazzi and colleagues, “detected viral particles in cardiac macrophages in an adult patient with acute cardiac injury associated with COVID-19; no viral particles were seen in cardiomyocytes or endothelial cells.
“Our case report is the first to our knowledge to document the presence of viral particles in the cardiac tissue of a child affected by MIS-C,” they added. “Moreover, viral particles were identified in different cell lineages of the heart, including cardiomyocytes, endothelial cells, mesenchymal cells, and inflammatory cells.”
‘Concerning’ case report
“This is a concerning report as it shows for the first time that the virus can actually invade the heart muscle cells themselves,” C. Michael Gibson, MD, CEO of the Baim Institute for Clinical Research in Boston, said in an interview.
“Previous reports of COVID-19 and the heart found that the virus was in the area outside the heart muscle cells. We do not know yet the relative contribution of the inflammatory cells invading the heart, the release of blood-borne inflammatory mediators, and the virus inside the heart muscle cells themselves to heart damage,” Dr. Gibson said.
The patient was a previously healthy 11-year-old girl of African descent with MIS-C related to COVID-19. She developed cardiac failure and died after 1 day in the hospital, despite aggressive treatment.
SARS-CoV-2 RNA was detected on a postmortem nasopharyngeal swab and in cardiac and pulmonary tissues by RT-PCR.
Postmortem ultrasound examination of the heart showed a “hyperechogenic and diffusely thickened endocardium (mean thickness, 10 mm), a thickened myocardium (18 mm thick in the left ventricle), and a small pericardial effusion,” Dr. Dolhnikoff and colleagues reported.
Histopathologic exam revealed myocarditis, pericarditis, and endocarditis characterized by infiltration of inflammatory cells. Inflammation was mainly interstitial and perivascular, associated with foci of cardiomyocyte necrosis and was mainly composed of CD68+ macrophages, a few CD45+ lymphocytes, and a few neutrophils and eosinophils.
Electron microscopy of cardiac tissue revealed spherical viral particles in shape and size consistent with the Coronaviridae family in the extracellular compartment and within cardiomyocytes, capillary endothelial cells, endocardium endothelial cells, macrophages, neutrophils, and fibroblasts.
Microthrombi in the pulmonary arterioles and renal glomerular capillaries were also seen at autopsy. SARS-CoV-2–associated pneumonia was mild.
Lymphoid depletion and signs of hemophagocytosis were observed in the spleen and lymph nodes. Acute tubular necrosis in the kidneys and hepatic centrilobular necrosis, secondary to shock, were also seen. Brain tissue showed microglial reactivity.
“Fortunately, MIS-C is a rare event and, although it can be severe and life threatening, most children recover,” Dr. Dolhnikoff commented.
“This case report comes at a time when the scientific community around the world calls attention to MIS-C and the need for it to be quickly recognized and treated by the pediatric community. Evidence of a direct relation between the virus and myocarditis confirms that MIS-C is one of the possible forms of presentation of COVID-19 and that the heart may be the target organ. It also alerts clinicians to possible cardiac sequelae in these children,” she added.
Experts weigh in
Scott Aydin, MD, medical director of pediatric cardiac intensive care, Mount Sinai Kravis Children’s Hospital in New York City, said that this case report is “unfortunately not all that surprising.
“Since the initial presentations of MIS-C several months ago, we have suspected mechanisms of direct and indirect injury to the myocardium. This important work is just the next step in further understanding the mechanisms of how COVID-19 creates havoc in the human body and the choices of possible therapies we have to treat children with COVID-19 and MIS-C,” said Dr. Aydin, who was not involved with the case report.
Anish Koka, MD, a cardiologist in private practice in Philadelphia, noted that, in these cases, endomyocardial biopsy is “rarely done because it is fairly invasive, but even when it has been done, the pathologic findings are of widespread inflammation rather than virus-induced cell necrosis.”
“While reports like this are sure to spawn viral tweets, it’s vital to understand that it’s not unusual to find widespread organ dissemination of virus in very sick patients. This does not mean that the virus is causing dysfunction of the organ it happens to be found in,” Dr. Koka said in an interview.
He noted that, in the case of the young girl who died, it took high PCR-cycle threshold values to isolate virus from the lung and heart samples.
“This means there was a low viral load in both organs, supporting the theory of SARS-CoV-2 as a potential trigger of a widespread inflammatory response that results in organ damage, rather than the virus itself infecting and destroying organs,” said Dr. Koka, who was also not associated with the case report.
This research had no specific funding. The authors declared no competing interests. Dr. Aydin disclosed no relevant financial relationships. Dr. Koka disclosed financial relationships with Boehringer Ingelheim and Jardiance.

SARS-CoV-2 has been found in cardiac tissue of a child from Brazil with multisystem inflammatory syndrome (MIS-C) related to COVID-19 who presented with myocarditis and died of heart failure.
It’s believed to be the first evidence of direct infection of heart muscle cells by the virus; viral particles were identified in different cell lineages of the heart, including cardiomyocytes, endothelial cells, mesenchymal cells, and inflammatory cells.
The case was described in a report published online August 20 in The Lancet Child & Adolescent Health.
“The presence of the virus in various cell types of cardiac tissue, as evidenced by electron microscopy, shows that myocarditis in this case is likely a direct inflammatory response to the virus infection in the heart,” first author Marisa Dolhnikoff, MD, department of pathology, University of São Paulo, said in an interview.
There have been previous reports in adults with COVID-19 of both SARS-CoV-2 RNA by reverse transcription–polymerase chain reaction (RT-PCR) and viral particles by electron microscopy in cardiac tissue from endomyocardial specimens, the researchers noted. One of these reports, published in April by Tavazzi and colleagues, “detected viral particles in cardiac macrophages in an adult patient with acute cardiac injury associated with COVID-19; no viral particles were seen in cardiomyocytes or endothelial cells.
“Our case report is the first to our knowledge to document the presence of viral particles in the cardiac tissue of a child affected by MIS-C,” they added. “Moreover, viral particles were identified in different cell lineages of the heart, including cardiomyocytes, endothelial cells, mesenchymal cells, and inflammatory cells.”

SYNTAXES: Female benefit with CABG vanishes by 10 years
The beneficial effect on all-cause mortality of coronary artery bypass grafting surgery observed at 4 and 5 years in women with complex coronary disease seen in the SYNTAX trial is gone at 10 years.
If anything, the results suggest a mortality benefit for coronary artery bypass grafting (CABG) over percutaneous coronary intervention (PCI) mainly for men (adjusted hazard ratio, 0.76; 95% confidence interval, 0.56-1.02) and not for women (adjusted HR, 0.90; 95% CI, 0.54-1.51) in the SYNTAX Extended Survival (SYNTAXES) study.
The sex-treatment interaction for all-cause mortality was significant at 5 years (P = .025) but not at 10 years (P = .952).
“I’m becoming very humble with trials because I’m not expecting the convergence of the curve. I was expecting like a surge, a further divergence,” senior author Patrick Serruys, MD, PhD, National University of Ireland, Galway, said in an interview. “You could say, at the end of the day, everybody dies. And that’s the life expectancy factor.”
Although female patients had slightly lower anatomic SYNTAX scores at randomization (27.0 vs. 29.2), they were on average 4 years older than men (mean age, 68 years) and had higher prevalence rates of diabetes, hypertension, and chronic kidney disease, he noted. “The other explanation is that we know that the bypass graft, the saphenous bypass graft, became vulnerable around 7 years; that’s probably the half-life.”
Overall, mortality in both men and women tended to be lower after CABG than after PCI, although the differences were not statistically significant, the authors reported August 17 in the Journal of the American College of Cardiology.
The 1,800-patient SYNTAX trial showed no difference in all-cause mortality at 5 years between CABG and PCI, although CABG was associated with fewer major adverse cardiac and cerebrovascular events (MACCE) and more favorable results among those with complex, three-vessel disease.
The findings were confirmed in 10-year follow-up reported last year from SYNTAXES, which analyzed only all-cause mortality.
Female sex, however, was an independent predictor of mortality with PCI at 4-years follow-up (HR, 2.87) in SYNTAX and led to sex being incorporated into the SYNTAX II score to help guide revascularization decisions. Notably, this interaction for all-cause mortality has not been seen in other studies.
Treatment effect by sex
In the new prespecified subgroup analysis, women had a higher crude rate of all-cause mortality at 10 years than men (32.8% vs. 24.7%; log-rank P = .002). This held true whether women were in the PCI group (33.0% vs. 27.0%; log-rank P = .053) or the CABG group (32.5% vs. 22.5%; log-rank P = .017).
In women, the mortality rate was significantly higher with PCI than with CABG at 5 years, but was no longer different at 10 years (33.0% vs. 32.5%; log-rank P = .601). This was largely caused by an uptick in deaths between 5 and 10 years in those treated with CABG, compared with PCI.
In men, the mortality rate was similar between PCI and CABG at 5 years, but tended to be higher with PCI at 10 years (27.0% vs. 22.5%; log-rank P = .082).
Asked about the possible late benefit for CABG in men, Dr. Serruys replied: “Of course, everyone had made a hypothesis – ‘let’s look at the use of internal mammary arteries in these patients, etc.’ – but I must be honest, we don’t have an explanation so far.”
Roxana Mehran, MD, Mount Sinai School of Medicine, New York City, said with just 402 women and using a no-longer-available, first-generation (Taxus) stent, the findings are, unfortunately, not informative.
“For me, it would be important for these investigators to share their data for women so we can do a patient-based analysis to better figure out the differential between first-generation stents and how well we’re doing,” Dr. Mehran said.
“What’s really important is to have a study where you actually collect female-specific risk factors that are never, ever looked at, [such as] age at menopause or having had pregnancy-related complications, that predispose these women to more of an atherosclerotic risk. And, even so, to better understand their anatomy and what suits them better,” she said. “I just don’t think we know enough or have put enough effort into understanding the biology that is sex specific and different for men and women.”
Revising SYNTAX II score
Given the lack of a sex-treatment interaction in the analysis, Dr. Serruys and colleagues suggest that the SYNTAX II score “should be reevaluated for the prediction of all-cause mortality at 10 years.”
Lending further support to this is the fact that SYNTAX II score was similar between women who died at 5-10 years and those who died in the first 5 years after CABG (31.8 vs. 31.6).
“The authors rightfully ask whether the SYNTAX II score should be revised to remove female sex, and given the current study result this appears warranted,” Arnold H. Seto, MD, MPA, Long Beach (Calif.) Veterans Administration Hospital, said in a related editorial.
He pointed out that women in SYNTAXES treated with CABG tended to have a survival time 0.51 years longer than women treated with PCI (P = .07). Nonetheless, the lack of confirmation for a sex-specific treatment interaction in any other study – EXCEL, FREEDOM, BEST, PRECOMBAT, BARI, or MASS – strongly suggests that the interaction seen in SYNTAX is likely a “type 1 error.”
Rather than focusing on early mortality, which may represent relatively rare events that are susceptible to chance, Dr. Seto suggested “other endpoints such years of life saved, quality adjusted life-years, and MACE may better capture the benefits of different revascularization decisions, even if they have a higher risk for bias.”
A new risk model, SYNTAX score 2020, has been developed and will be published imminently, Dr. Serruys said in an interview.
The SYNTAX Extended Survival study was supported by the German Foundation of Heart Research. The SYNTAX trial, during 0- to 5-years of follow-up, was funded by Boston Scientific. Both sponsors had no role in study design or data collection, analyses, and interpretation, nor were they involved in the decision to publish the final manuscript. Dr. Serruys has received personal fees from Biosensors, Micel Technologies, Sinomedical Sciences Technology, Philips/Volcano, Xeltis, and HeartFlow, outside the submitted work. Dr. Seto reported research grants from Philips and Acist, and honoraria from Terumo, Getinge, Boston Scientific, General Electric, and Janssen.

“What’s really important is to have a study where you actually collect female-specific risk factors that are never, ever looked at, [such as] age at menopause or having had pregnancy-related complications, that predispose these women to more of an atherosclerotic risk. And, even so, to better understand their anatomy and what suits them better,” she said. “I just don’t think we know enough or have put enough effort into understanding the biology that is sex specific and different for men and women.”
Revising SYNTAX II score
Given the lack of a sex-treatment interaction in the analysis, Dr. Serruys and colleagues suggest that the SYNTAX II score “should be reevaluated for the prediction of all-cause mortality at 10 years.”
Lending further support to this is the fact that SYNTAX II score was similar between women who died at 5-10 years and those who died in the first 5 years after CABG (31.8 vs. 31.6).
“The authors rightfully ask whether the SYNTAX II score should be revised to remove female sex, and given the current study result this appears warranted,” Arnold H. Seto, MD, MPA, Long Beach (Calif.) Veterans Administration Hospital, said in a related editorial.
He pointed out that women in SYNTAXES treated with CABG tended to have a survival time 0.51 years longer than women treated with PCI (P = .07). Nonetheless, the lack of confirmation for a sex-specific treatment interaction in any other study – EXCEL, FREEDOM, BEST, PRECOMBAT, BARI, or MASS – strongly suggests that the interaction seen in SYNTAX is likely a “type 1 error.”
Rather than focusing on early mortality, which may represent relatively rare events that are susceptible to chance, Dr. Seto suggested “other endpoints such years of life saved, quality adjusted life-years, and MACE may better capture the benefits of different revascularization decisions, even if they have a higher risk for bias.”
A new risk model, SYNTAX score 2020, has been developed and will be published imminently, Dr. Serruys said in an interview.
The SYNTAX Extended Survival study was supported by the German Foundation of Heart Research. The SYNTAX trial, during 0- to 5-years of follow-up, was funded by Boston Scientific. Both sponsors had no role in study design or data collection, analyses, and interpretation, nor were they involved in the decision to publish the final manuscript. Dr. Serruys has received personal fees from Biosensors, Micel Technologies, Sinomedical Sciences Technology, Philips/Volcano, Xeltis, and HeartFlow, outside the submitted work. Dr. Seto reported research grants from Philips and Acist, and honoraria from Terumo, Getinge, Boston Scientific, General Electric, and Janssen.

FDA updates hydrochlorothiazide label to include nonmelanoma skin cancer risk
and undergo regular skin cancer screening, according to updates to the medication’s label.
The skin cancer risk is small, however, and patients should continue taking HCTZ, a commonly used diuretic and antihypertensive drug, unless their doctor says otherwise, according to a U.S. Food and Drug Administration announcement about the labeling changes, which the agency approved on Aug. 20.
HCTZ, first approved in 1959, is associated with photosensitivity. Researchers identified a relationship between HCTZ and nonmelanoma skin cancer in postmarketing studies. Investigators have described dose-response patterns for basal cell carcinoma and squamous cell carcinoma (SCC).
An FDA analysis found that the risk mostly was increased for SCC. The drug was associated with approximately one additional case of SCC per 16,000 patients per year. For white patients who received a cumulative dose of 50,000 mg or more, the risk was greater. In this patient population, HCTZ was associated with about one additional case of SCC per 6,700 patients per year, according to the label.
Reliably estimating the frequency of nonmelanoma skin cancer and establishing a causal relationship to drug exposure is not possible with the available postmarketing data, the label notes
“Treatment for nonmelanoma skin cancer is typically local and successful, with very low rates of death,” the FDA said. “Meanwhile, the risks of uncontrolled blood pressure can be severe and include life-threatening heart attacks or stroke. Given this information, patients should continue to use HCTZ and take protective skin care measures to reduce their risk of nonmelanoma skin cancer, unless directed otherwise from their health care provider.”
Patients can reduce sun exposure by using broad-spectrum sunscreens with a sun protection factor value of at least 15, limiting time in the sun, and wearing protective clothing, the agency advised.

Humira topped drug-revenue list for 2019
Humira outsold all other drugs in 2019 in terms of revenue as cytokine inhibitor medications earned their way to three of the first four spots on the pharmaceutical best-seller list, according to a new analysis from the IQVIA Institute for Human Data Science.
Sales of Humira (adalimumab) amounted to $21.4 billion before discounting, Murray Aitken, the institute’s executive director, and associates wrote in their analysis. That’s more than double the total of the anticoagulant Eliquis (apixaban), which brought in $9.9 billion in its last year before generic forms became available.
The next two spots were filled by the tumor necrosis factor inhibitor Enbrel (etanercept) with $8.1 billion in sales and the interleukin 12/23 inhibitor Stelara (ustekinumab) with sales totaling $6.6 billion, followed by the chemotherapy drug Keytruda (pembrolizumab) close behind after racking up $6.5 billion in sales, the researchers reported.
Total nondiscounted spending on all drugs in the U.S. market came to $511 billion in 2019, an increase of 5.7% over the $484 billion spent in 2018, based on data from the July 2020 IQVIA National Sales Perspectives.
These figures are “not adjusted for estimates of off-invoice discounts and rebates,” the authors noted, but they include “prescription and insulin products sold into chain and independent pharmacies, food store pharmacies, mail service pharmacies, long-term care facilities, hospitals, clinics, and other institutional settings.”
Those “discounts and rebates” do exist, however, and they can add up. Drug sales for 2019, “after deducting negotiated rebates, discounts, and other forms of price concessions, such as patient coupons or vouchers that offset out-of-pocket costs,” were $235 billion less than overall nondiscounted spending, the report noted.
Now that we’ve shown you the money, let’s take a quick look at volume. The leading drugs by number of dispensed prescriptions in 2019 were, not surprisingly, quite different. First, with 118 million prescriptions, was atorvastatin, followed by levothyroxine (113 million), lisinopril (96), amlodipine (89), and metoprolol (85), Mr. Aitken and associates reported.
Altogether, over 4.2 billion prescriptions were dispensed last year, with a couple of caveats: 90-day and 30-day fills were both counted as one prescription, and OTC drugs were not included, they pointed out.

Oleander extract for COVID-19? That’s a hard ‘no’ experts say
“Though renowned for its beauty and use in landscaping, this Mediterranean shrub is responsible for cases of accidental poisoning across the globe. All parts of the plant are poisonous,” Cassandra Quave, PhD, ethnobotanist and herbarium curator at Emory University, Atlanta, cautioned in an article in The Conversation, an independent, not-for-profit publication.
Oleandrin has properties similar to digoxin; the onset of toxicity occurs several hours after consumption.
The first symptoms of oleandrin poisoning may be gastrointestinal, such as nausea, vomiting, abdominal pain, diarrhea (which may contain blood), and loss of appetite.
After these first symptoms, the heart may be affected by tachyarrhythmia, bradyarrhythmia, premature ventricular contractions, or atrioventricular blockage. Xanthopsia (yellow vision), a burning sensation in the eyes, paralysis of the gastrointestinal tract, and respiratory symptoms may also occur.
Oleandrin poisoning may affect the central nervous system, as evidenced by drowsiness, tremors, seizures, collapse, and coma leading to death. When applied to the skin, oleander sap can cause skin irritations and allergic reactions characterized by dermatitis.
Diagnosis of oleandrin poisoning is mainly made on the basis of a description of the plant, how much of it was ingested, how much time has elapsed since ingestion, and symptoms. Confirmation of oleandrin in blood involves fluorescence polarization immunoassay, digoxin immunoassay, or liquid chromatography-electrospray tandem mass spectrometry.
Neither oleander nor oleandrin is approved by regulatory agencies as a prescription drug or dietary supplement.
In vitro study
Oleandrin for COVID-19 made headlines after President Trump met in the Oval Office with Andrew Whitney, vice chairman and director of Phoenix Biotechnology, along with Housing and Urban Development Secretary Ben Carson, MD, and MyPillow founder/CEO Mike Lindell, a strong supporter of Trump and an investor in the biotech company, to learn about oleandrin, which Whitney called a “cure” for COVID-19, Axios reported.
In an in vitro study, researchers from Phoenix Biotechnology and the University of Texas Medical Branch, Galveston, tested oleandrin against SARS-CoV-2 in cultured Vero cells.
“When administered both before and after virus infection, nanogram doses of oleandrin significantly inhibited replication by 45 to 3000-fold,” the researchers said in an article posted on bioRxiv, a free online archive and distribution service for unpublished preprints in the life sciences. The study has not been peer reviewed.
On the basis of these in vitro findings, the researchers said the plant extract has “potential to prevent disease and virus spread in persons recently exposed to SARS-CoV-2, as well as to prevent severe disease in persons at high risk.”
But it’s a far cry from test tube to human, one expert cautioned.
“This is an understatement: Care must be taken when inferring potential therapeutic benefits from in vitro antiviral effects,” Harlan Krumholz, MD, cardiologist and director, Yale New Haven Hospital Center for Outcomes Research and Evaluation, New Haven, Connecticut, told Medscape Medical News.
“There is a chasm between a single in vitro study and any use in humans outside of a protocol. People should be cautioned about that distance and the need [to] avoid such remedies unless part of a credible research project,” said Krumholz.
Yet Lindell told Axios that, in the Oval Office meeting, Trump expressed enthusiasm for the Food and Drug Administration to allow oleandrin to be marketed as a dietary supplement or approved for COVID-19.
“This is really just nonsense and a distraction,” Jonathan Reiner, MD, of George Washington University Medical Center, Washington, DC, said on CNN.

Pulmonary artery denervation eases PAH after endarterectomy
Pulmonary artery denervation (PADN) provides persistent and clinically significant hemodynamic improvements in patients with persistent chronic thromboembolic hypertension (CTEPH) after pulmonary endarterectomy (PEA), according to a randomized, sham-controlled trial.
“PADN in patients with CTEPH after PEA was safe and effective,” according to an investigating team led by Alexander Romanov, MD, PhD.
The mean reduction in pulmonary vascular resistance (PVR) was 258 dyn/sec per cm–5 for those randomized to PADN versus 149 dyn/sec per cm–5 (P = .001) for those randomized to the sham procedure, according to the newly published findings.
For the 6-minute walk test (6MWT), the mean distance was 470 m for the experimental group versus 399 m (P = .03) for the controls.
Several secondary endpoints measuring hemodynamics also favored PADN relative to the sham procedure at 12 months. This included the relative increase in tricuspid annular systolic excursion (P = .03) and the increase in the right ventricular fraction area (P < .001).
A total of 50 patients with residual CTEPH for at least 6 months after PEA despite medical therapy were enrolled and randomized. Entry criteria included a mean pulmonary artery pressure (PAP) of 25 mm Hg or greater or PVR greater than 400 dyn/sec per cm–5 on right heart catheterization. Patients with comorbidities associated with a life expectancy of less than 1 year were excluded.
Those randomized to the sham group were treated with riociguat over the course of follow-up. This therapy was not offered to patients in the PADN group, but all patients were blinded to the procedure and told that riociguat might or might not be administered.
Following the procedure, participating clinicians, who were also blinded to the procedure, were instructed to provide standard therapies for heart failure, such beta-blockers, diuretics, or digoxin, as needed. All patients were placed on an oral anticoagulant.
At 12 months the mean PAP (26 vs. 35 mm Hg; P < .001) and the mean systolic PAP (46 vs. 54 mm Hg; P = .01) were significantly lower in the PADN group versus those who underwent a sham procedure.
About 52% of the PADN group versus 12% of the sham group were classified as responders by the definition of a PVR reduction of at least 150 dyn/sec per cm–5 and 6MWT improvement of at least 20%, compared with baseline, reported Dr. Romanov, of the E. Meshalkin National Medical Research Center, ministry of health, Novosibirsk, Russia, and coinvestigators.
Of the three deaths caused by heart failure over the course of follow-up, two occurred in the sham group. Of the eight hospitalizations for heart failure, seven (29% of the sham group) occurred among controls versus one in those treated with PADN (4% of this group; P = .049).
There was one groin hematoma at the puncture site in each group. Both resolved without any consequences prior to hospital discharge. There were no other significant procedure-related complications in either group.
Larger multicenter trials are needed to confirm these findings, according to both the trial investigators and Marius M. Hoeper, MD, who is charge of the pulmonary hypertension program at the Hannover (Germany) Medical School.
In an editorial that accompanied publication of these findings, Dr. Hoeper identified the small sample size of this study as one of its limitations, but he said the results are consistent with several other small studies associating pulmonary artery denervation with benefit in pulmonary hypertension.
“It appears as if we are currently witnessing the emergence of a new treatment option for various forms of pulmonary hypertension,” Dr. Hoeper wrote. In his critique of the study, he suggested that it would have been “more informative” if both groups were on background riociguat, but the data from this and other studies so far indicates that ablation to achieve denervation “is safe and feasible.”
The PADN technique used in this study might be relevant to the results. Dr. Hoeper noted that the investigators employed catheter tip–based electroanatomic mapping with a novel remote navigation system with three-dimensional imaging of the right ventricle and central pulmonary arteries.
“Apparently, this approach minimizes radiation exposure and provides precise location of ablation sites,” Dr. Hoeper observed. However, he called for direct comparisons of this tool to the guidance systems used in other studies.
In an interview, Dr. Hoeper acknowledged that it is not yet clear that a large-scale trial of pulmonary artery denervation for the indication evaluated in this study is coming. He noted several strategies in CTEPH are widely used without trials confirming a reduction in clinical events.
“Balloon pulmonary angioplasty for CTEPH has become an established treatment around the world without any randomized, controlled trial and without demonstration of improved outcomes. A couple of well-conducted observational trials might be sufficient to convince physicians to introduce PADN as well,” he said. If such studies associated PADN with “improvements in hemodynamics, exercise capacity, and patient-reported outcomes, it might be sufficient.”
Currently, Dr. Hoeper is most concerned about obtaining further evidence of safety, which he characterized as a “major issue.”
If a multicenter trial is conducted “the primary endpoint should be focused on clinical events,” according to Dr. Romanov, who was asked to comment on the next steps in validating PADN for the treatment of CTEPH-associated pulmonary hypertension persisting after endarterectomy.
“The mortality rate during 1-year long-term follow-up is not so high, but heart failure progression is a problem. So in my view, the primary endpoint should be a composite of death and heart failure hospitalization,” he said. He called for follow-up duration of 2-3 years.
Jonathan Steinberg, MD, director of cardiac clinical trials and education, Summit Medical Group, Montclair, N.J., also called a trial with hard endpoints, such as death, the ideal.
In the meantime, hemodynamic and functional measures “are still quite valuable and move the ball forward for this intervention,” he said in an interview. Senior author of this trial and principle investigator of the recent ERADICATE-AF trial, which evaluated renal denervation in preventing recurrence of atrial fibrillation (JAMA. 2020;323:248-55), Dr. Steinberg predicted, “I do indeed suspect we will see trials that are more accomplishable [than a large-scale, randomized, controlled trial] in the not too distant future.”
Dr. Romanov received funding from Biosense Webster. Dr. Hoeper has received fees for lectures and/or consultations from Acceleron, Actelion, Bayer, Janssen, Merck Sharp & Dohme, and Pfizer.

Machine learning shows ability to predict diastolic dysfunction with ECG
A machine-learning model that uses readily available clinical and electrocardiography data may have the potential to identify left ventricular (LV) diastolic dysfunction, a key biomarker in predicting heart failure, without echocardiography, but a workable clinical platform is still far off, a team of North American researchers reported.
“This cost-effective strategy may be a valuable first clinical step for assessing the presence of LV dysfunction and may potentially aid in the early diagnosis and management of heart failure patients,” Nobuyuki Kagiyama, MD, PhD, of West Virginia University, Morgantown, and colleagues, wrote in the Journal of the American Academy of Cardiology.
The researchers reported on a multicenter, prospective study that evaluated 1,202 patients from three centers in the United States and one in Canada. To develop machine-learning models, the study pooled 814 patients from the U.S. institutions as an internal cohort. They were then randomly divided into a training set and an internal test set on an 80:20 basis (651 and 163). The 388 Canadian patients were reserved as an external set to test the model.
All patients had 12-lead ECG and simultaneous body surface signal-processed ECG (spECG) along with comprehensive two-dimensional Doppler ECG on the same day.
How the model works
The machine-learning model estimated echocardiographic LV relaxation velocities (e’) values using traditional ECG and spECG features. The model also took into account 10 basic clinical features: age; sex; systolic and diastolic blood pressure; and comorbid conditions such as cerebrovascular and cardiovascular disease, diabetes, hypertension, dyslipidemia, and chronic kidney disease.
Patient characteristics were starkly different between the internal (United States) and external (Canadian) cohorts, with the latter being 10 years older on average (65 vs. 44; P < .001), predominantly male (58.2% vs. 47.3%; P < .001) and with significantly lower rates of coronary artery disease (1.8% vs. 21.1%; P < .001), although average blood pressure was similar between the two groups.
The study used area under the curve (AUC) to calculate the predictability of the machine-learning estimated e’ values versus the guideline-based reduced e’, finding close correlation between the internal (AUC, 0.83; sensitivity, 78%; specificity, 77%; negative predictive value, 73%; and positive predictive value, 82%) and external test sets (AUC, 0.84; sensitivity, 90%; specificity, 61%; NPV, 81%; and PPV, 77%).
Similar variations between the two cohorts were reported for global LV diastolic dysfunction and reduced LV ejection fraction.
The final model used 18 features in all, including 3 clinical features (age, dyslipidemia, and hypertension), 7 scores from spECG features, and 8 from traditional ECG features.
Interpreting the results
Dr. Kagiyama and colleagues noted that, because impaired myocardial relaxation is an early sign of cardiac tissue deterioration, screening for it can aid in early detection of subclinical LVDD and earlier treatment for hypertension and diabetes. But they acknowledged that further studies are needed.
In an invited editorial, Khurram Nasir, MD, MPH, MSc, of Houston Methodist DeBakey Heart and Vascular Center and Rohan Khera, MD, MS, of Yale University, New Haven, Conn., wrote that the machine-learning model has a way to go.
They noted that the 73%-77% accuracy of the model in identifying diastolic dysfunction impedes its imminent use. “Although we are excited about the prospects of such developments, we hold out for better evidence for their actual use,” they wrote, adding that the algorithms have limited use in the clinic because most patients already get “definitive testing” if they need it.
Developing a machine-learning model that obviates the need for ECG for evaluating LV diastolic dysfunction seems dubious at this time, said Luigi Di Biase, MD, PhD, section head of electrophysiology and director of arrhythmia services at Montefiore Medical Center and professor at Albert Einstein College of Medicine, both in New York. “The echo is not a difficult test. It’s the most proven usable tool that we have in cardiology because it’s easy to reproduce, low cost, and noninvasive – so we have all that we want in medicine.”
But machine learning does have potential, added Dr. Di Biase, who’s also a member of the American College of Cardiology’s Electrophysiology Section Leadership Council. “If this application could predict the people that would develop diastolic dysfunction that leads to heart failure – because an echo at that time may be negative but there may be other features that tell me this patient will develop disease – then it would have a much different clinical impact.”
The National Science Foundation provided funding for the study. Heart Test Laboratories, doing business as Heart Sciences, provided funding and spECG devices. Dr. Kagiyama reported receiving a research grant from Hitachi Healthcare. A coauthor disclosed financial relationships with Heart Sciences, Ultronics, and Kencor Health.
