As mutated strains of the coronavirus represent new threats in the pandemic, vaccine makers are racing to respond.

Moderna, whose two-dose vaccine has been authorized for use in the United States since Dec. 18, said on Jan. 25 that it is now investigating whether a third dose of the vaccine will better prevent the spread of a variant first seen in South Africa, while it also tests a new vaccine formula for the same purpose.

“Out of an abundance of caution and leveraging the flexibility of our mRNA platform, we are advancing an emerging variant booster candidate against the variant first identified in the Republic of South Africa into the clinic to determine if it will be more effective … against this and potentially future variants,” Moderna CEO Stéphane Bancel said in a statement. Pfizer and BioNTech, whose vaccine was also authorized in December, announced on Jan. 20 that their COVID-19 vaccine creates antibodies that could protect vaccine recipients from the U.K. variant B.1.1.7.

Moderna on Jan. 25 said laboratory tests have shown its COVID-19 vaccine could protect against the U.K. strain but that it is less effective – while still meeting efficacy benchmarks – against the strain identified in South Africa. Data from the study were submitted to a preprint server on Jan. 25 but have not yet been peer reviewed.

“This is not a problem yet,” Paul Offit, MD, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, told CNBC.

“Prepare for it. Sequence these viruses,” he said. “Get ready just in case a variant emerges, which is resistant.”

There were at least 195 confirmed cases of patients infected with the U.K. variant, which is believed to be as much as 70% more transmissible, in the United States as of Jan. 22, according to the Centers for Disease Control and Prevention. No cases from the South African variant have been confirmed in the United States. To try to prevent the variant from entering the country, President Joe Biden plans to ban travel from South Africa, except for American citizens and permanent residents.

The U.S. has reported more than 25 million total COVID-19 cases, according to data from Johns Hopkins University, marking another major milestone during the pandemic.

That means about 1 in 13 people have contracted the virus, or about 7.6% of the U.S. population.

“Twenty-five million cases is an incredible scale of tragedy,” Caitlin Rivers, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, told The New York Times. She called the pandemic one of the worst public health crises in history.

After the first U.S. case was reported in January 2020, it took more than 9 months to reach 10 million cases in early November. Numbers rose during the holidays, and 10 million more cases were reported by the end of the year.

Following a major surge throughout January 2021, with a peak of more than 300,000 daily cases on some days, the U.S. reached 25 million in about 3 weeks.

Hospitalizations also peaked in early January, with more than 132,000 COVID-19 patients in hospitals across the country, according to the COVID Tracking Project. On Jan. 24, about 111,000 patients were hospitalized, which is the lowest since mid-December.

The U.S. has also reported nearly 420,000 deaths. As recently as the week starting Jan. 17, more than 4,400 deaths were reported in a single day, according to the COVID Tracking Project. Deaths are beginning to drop but still remain above 3,000 daily.

The University of Washington’s Institute for Health Metrics and Evaluation released a new projection Jan. 22 that said new cases would decline steadily in coming weeks. New COVID-19 cases had fallen about 21% in 2 weeks prior to Jan. 25, according to an analysis by The New York Times.

“We’ve been saying since summer that we thought we’d see a peak in January, and I think that, at the national level, we’re around the peak,” Christopher J.L. Murray, MD, director of the institute, told the newspaper.

At the same time, public health officials are concerned that new coronavirus variants could lead to an increase again. Dr. Murray said the variants could “totally change the story.” If the more transmissible strains spread quickly, cases and deaths will surge once more.

“We’re definitely on a downward slope, but I’m worried that the new variants will throw us a curveball in late February or March,” Ms. Rivers told the newspaper.

It’s been shown that hospitalized cancer patients and those undergoing active treatment are at high risk for severe COVID-19 complications. A new study shows that patients with cancer in remission are at higher risk, too.

For the study, investigators from the University of Pennsylvania, Philadelphia, analyzed 323 patients with SARS-CoV-2 infection in a research database with more than 4,800 patients. About 20% of database patients were Black, but they accounted for almost 65% of the infections, reflecting previous reports of increased risk for COVID among Black people.

A total of 67 of the infected patients had cancer, including 18 patients with active cancer and 49 patients whose cancer was in remission. After adjusting for demographics, smoking status, and comorbidities, a diagnosis of cancer more than doubled the odds of hospitalization and increased the odds of 30-day mortality nearly sixfold.

Worse outcomes were more strongly associated with active cancer, but patients whose cancer was in remission were also at higher risk than patients who did not have cancer.

It’s not only “patients hospitalized or on treatment ... all oncology patients need to take significant precautions during the pandemic to protect themselves,” senior investigator Kara Maxwell, MD, PhD, hematologist/oncologist and assistant professor at the University of Pennsylvania, said in a press release.

The study was published online on Jan. 21 in JNCI Cancer Spectrum.

The good news is that steps to prevent SARS-CoV-2 infection work, suggests a second report from the University of Pennsylvania. Among 124 cancer patients who underwent outpatient infusions from May to October 2020, not a single one experienced seroconversion over a median of 13 clinical visits. That second study was published on Jan. 16 in medRxiv and is pending peer review.

The zero seroconversion rate likely reflects “the success of transmission mitigation measures within health care facilities,” wrote investigators led by Lova Sun, MD, a hematology/oncology fellow at the University of Pennsylvania.

Like many institutions, the University of Pennsylvania Health System (Penn Medicine) is aggressive in protecting outpatients against the virus, the authors wrote. Among other steps, patients are queried about symptoms and contacts before their office visit, and their temperature is taken when they come in. Masks are worn, check-in is contactless, the number of visitors is limited, and patients who test positive are treated in a separate space.

In addition, patients in the study also reported that they wore masks and practiced social distancing in their daily lives.

Approached for comment, hematologist/oncologist Charles Shapiro, MD, a professor at the Icahn School of Medicine at Mount Sinai and director of translational breast cancer research at Mount Sinai Hospital, both in New York, said he wasn’t surprised that the prevention measures followed at Penn Medicine work. They are very similar to the measures followed at Mount Sinai oncology clinics, and “there’ve been very few COVID cases in our shop,” he added.

The bigger take-home message from both studies is that cancer patients, regardless of their age or if they are in remission, should be prioritized for vaccination against COVID-19, which is the best way to mitigate risk. “I strongly urge my patients to get it” if they can, he said.

The problem in New York is that immunizations are largely limited to people aged 65 years and older. Younger cancer patients are left out, and access has been spotty for all patients. “Vaccine is available one day, then not the next. It’s disheartening,” Dr. Shapiro said in an interview. “Hopefully, with the new administration, this will smooth out,” and the age limit will drop.

The study was supported by the National Institutes of Health, among other organizations. Dr. Lova, Dr. Maxwell, and Dr. Shapiro have disclosed no relevant financial relationships.

A systematic review suggests at least one-third of SARS-CoV-2 infections occur in people who never develop symptoms, providing strong evidence for the prevalence of asymptomatic infections.

The finding that nearly one in three infected people remain symptom free suggests testing should be changed, the investigators noted.

“To reduce transmission from people who are presymptomatic or asymptomatic, we need to shift our testing focus to at-home screening,” lead author Daniel Oran, AM, said in an interview. “Inexpensive rapid antigen tests, provided to millions of people for frequent use, could help us significantly reduce the spread of the virus.”

The systematic review was published online Jan. 22 in Annals of Internal Medicine.

The findings come at a dire time when the official number of COVID-19 cases in the United States exceeds 25 million for the first time. Public health officials have raised concerns about more transmissible, and possibly more deadly, variants of SARS-CoV-2, while a new presidential administration tries to meet the challenge of improving vaccine distribution and acceptance rates.

The results also build on earlier findings from the same research team – Mr. Oran and senior author Eric Topol, MD – that published a review article looking at asymptomatic COVID-19 cases. Even though initial data were more limited, they likewise suggested a broader scope of testing is warranted, pointing out that asymptomatic individuals can transmit SARS-CoV-2 for up to 14 days. Dr. Topol is also editor in chief of Medscape.

In the current systematic review, the highest-quality evidence comes from large studies in England and Spain. The nationally representative evidence included serologic surveys from more than 365,000 people in England and more than 61,000 in Spain. When analyzed separately, about the same proportion of asymptomatic cases emerged: 32.4% in England and 33% in Spain.

“It was really remarkable to find that nationwide antibody testing studies in England and Spain – including hundreds of thousands of people – produced nearly identical results: About one-third of the SARS-CoV-2 infections were completely asymptomatic,” said Mr. Oran, a researcher at Scripps Research Translational Institute in La Jolla, Calif.

The systematic review included 43 studies with PCR testing for active SARS-CoV-2 infection and another 18 with antibody results that indicated present or previous infection. The studies were published up until Nov. 17, 2020.

An appreciation for asymptomatic transmission of SARS-CoV-2 infection has come a long way from initial dismissals about its importance, Dr. Topol noted via Twitter. “When Dr. @camilla_rothe reported an asymptomatic transmission a year ago, the @NEJM report was refuted and disparaged. She was later named a TIME 100 Person of the Year.”
 

Not symptomatic vs. never symptomatic

The term “asymptomatic” could be misleading because some people in this group do progress to develop signs of infection. This “presymptomatic” group of patients is likely a minority, the authors noted. Longitudinal studies indicate that about three-quarters of people who are asymptomatic with SARS-CoV-2 remain so.

Dr. Topol anticipated the one-third asymptomatic finding could draw some feedback about distinguishing asymptomatic from presymptomatic individuals. He tweeted, “Some will argue that there is admixture with presymptomatic cases, but review of all the data supports this estimate as being a conservative one.”

The heterogeneity of the settings, populations and other features of the studies prevented the authors from performing a meta-analysis of the findings.
 

Home is where the test is

Based on their findings, Mr. Oran and Dr. Topol believe “that COVID-19 control strategies must be altered, taking into account the prevalence and transmission risk of asymptomatic SARS-CoV-2 infection.” They suggested frequent use of inexpensive, rapid home tests to identify people who are asymptomatic or presymptomatic, along with programs and housing provided by the government to offer financial assistance and allow this group of people to isolate themselves.

Further research is warranted to determine if and how well vaccines for SARS-CoV-2 prevent asymptomatic infection.

Dr. Topol and Mr. Oran created a short video to highlight the findings from their systematic review.

The study was supported by a grant from the National Institutes of Health.

The nationally representative evidence included serologic surveys from more than 365,000 people in England and more than 61,000 in Spain. When analyzed separately, about the same proportion of asymptomatic cases emerged: 32.4% in England and 33% in Spain.

“It was really remarkable to find that nationwide antibody testing studies in England and Spain – including hundreds of thousands of people – produced nearly identical results: About one-third of the SARS-CoV-2 infections were completely asymptomatic,” said Mr. Oran, a researcher at Scripps Research Translational Institute in La Jolla, Calif.

The systematic review included 43 studies with PCR testing for active SARS-CoV-2 infection and another 18 with antibody results that indicated present or previous infection. The studies were published up until Nov. 17, 2020.

An appreciation for asymptomatic transmission of SARS-CoV-2 infection has come a long way from initial dismissals about its importance, Dr. Topol noted via Twitter. “When Dr. @camilla_rothe reported an asymptomatic transmission a year ago, the @NEJM report was refuted and disparaged. She was later named a TIME 100 Person of the Year.”
 

Not symptomatic vs. never symptomatic

The term “asymptomatic” could be misleading because some people in this group do progress to develop signs of infection. This “presymptomatic” group of patients is likely a minority, the authors noted. Longitudinal studies indicate that about three-quarters of people who are asymptomatic with SARS-CoV-2 remain so.

Dr. Topol anticipated the one-third asymptomatic finding could draw some feedback about distinguishing asymptomatic from presymptomatic individuals. He tweeted, “Some will argue that there is admixture with presymptomatic cases, but review of all the data supports this estimate as being a conservative one.”

The heterogeneity of the settings, populations and other features of the studies prevented the authors from performing a meta-analysis of the findings.
 

Home is where the test is

Based on their findings, Mr. Oran and Dr. Topol believe “that COVID-19 control strategies must be altered, taking into account the prevalence and transmission risk of asymptomatic SARS-CoV-2 infection.” They suggested frequent use of inexpensive, rapid home tests to identify people who are asymptomatic or presymptomatic, along with programs and housing provided by the government to offer financial assistance and allow this group of people to isolate themselves.

Further research is warranted to determine if and how well vaccines for SARS-CoV-2 prevent asymptomatic infection.

Dr. Topol and Mr. Oran created a short video to highlight the findings from their systematic review.

The study was supported by a grant from the National Institutes of Health.

The current COVID-19 vaccines may not be as effective against new coronavirus variants, but they should be powerful enough to still be beneficial, Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said during a news briefing on Jan. 21.

Both vaccines from Pfizer-BioNTech and Moderna have such high efficacy rates that it creates a “cushion effect,” he said, meaning that new variants will likely only diminish vaccine efficacy slightly. To slow the spread of the new strains, Dr. Fauci said, people should get vaccinated as soon as possible. If viruses can’t spread as far or as quickly, they won’t mutate as much.

“Bottom line: We’re paying very close attention to it,” he said. “There are alternative plans if we ever have to modify the vaccine.”

The U.S. has reported 144 cases of the B.1.1.7 variant, which was first identified in the United Kingdom, according to the latest update from the CDC. So far, no cases of the variant strain identified in South Africa have been reported in the U.S., but Dr. Fauci said public health officials are looking for it.

“We’re following very carefully the one in South Africa, which is a little bit more concerning, but nonetheless not something that we don’t think we can handle,” he said.

Despite challenges with vaccine distribution and administration, the U.S. “can and should” vaccinate 70% to 85% of adults by the end of the summer, Dr. Fauci told CNN. If that happens, people could begin to return to some sense of normalcy by the fall, he added.

“When you put ... the pedal to the floor, you can get it done,” he said.

If the U.S. administered one million shots per day, it would take until the end of 2021 to fully vaccine 75% of adults, according to a CNN analysis. Dr. Fauci said he believes the U.S. can give more than one million shots per day. An updated tally from the CDC showed that 1.6 million shots were given in the past 24 hours, which was the largest single-day increase yet reported.

“I’d like it to be a lot more,” Dr. Fauci told CNN. “If we can do better than that, which I personally think we likely will, then great.”

The oral, anti-inflammatory drug colchicine can prevent complications and hospitalizations in nonhospitalized patients newly diagnosed with COVID-19, according to a press release from the ColCORONA trial investigators.

After 1 month of therapy, there was a 21% risk reduction in the primary composite endpoint of death or hospitalizations that missed statistical significance, compared with placebo among 4,488 outpatients enrolled in the global, phase 3 trial.

After excluding 329 patients without a confirmatory polymerase chain reaction test, however, the use of colchicine was reported to significantly reduce hospitalizations by 25%, the need for mechanical ventilation by 50%, and deaths by 44%.

“We believe that this is a medical breakthrough. There’s no approved therapy to prevent complications of COVID-19 in outpatients, to prevent them from reaching the hospital,” lead investigator Jean-Claude Tardif, MD, from the Montreal Heart Institute, said in an interview.

“I know that several countries will be reviewing the data very rapidly and that Greece approved it today,” he said. “So this is providing hope for patients.”

Having been burned by hydroxychloroquine and other treatments brought forth without peer review, the response to the announcement was tempered by a desire for more details.

Asked for comment, Steven E. Nissen, MD, of the Cleveland Clinic Foundation, was cautious. “The press release about the trial is vague and lacks details such as hazard ratios, confidence intervals, and P values,” he said in an interview.

“It is impossible to evaluate the results of this trial without these details. It is also uncertain how rigorously data were collected,” he added. “We’ll need to see the manuscript to adequately interpret the results.”

The evidence in the press release is hard to interpret, but early intervention with anti-inflammatory therapy has considerable biologic appeal in COVID, said Paul Ridker, MD, MPH, who led the pivotal CANTOS trial of the anti-inflammatory drug canakinumab in the post-MI setting, and is also chair of the ACTIV-4B trial currently investigating anticoagulants and antithrombotics in outpatient COVID-19.

“Colchicine is both inexpensive and generally well tolerated, and the apparent benefits so far reported are substantial,” Dr. Ridker, from Brigham and Women’s Hospital in Boston, said in an interview. “We are eager to see the full data as rapidly as possible.”

The commonly used gout and rheumatic disease agent costs about 26 cents in Canada and between $4 and $6 in the United States. As previously reported, it reduced the time to clinical deterioration and hospital stay but not mortality in the 105-patient Greek Study in the Effects of Colchicine in COVID-19 Complications Prevention (GRECCO-19) study.

Dr. Tardif said he’s looking forward to having the data in the public domain and that they acted swiftly because the evidence was “clinically persuasive” and “the health system is congested now.”

“We received the results Friday, Jan. 22 at 5 p.m., an hour later we were in meetings with our data safety monitoring board [DSMB], 2 hours later we issued a press release, and a day later we’re submitting a full manuscript to a major scientific journal, so I don’t know if anyone has done this at this speed,” he said. “So we are actually very proud of what we did.”

ColCORONA was designed to enroll 6,000 outpatients, at least 40 years of age, who were diagnosed with COVID-19 infection within the previous 24 hours, and had a least one high-risk criterion, including age at least 70 years, body mass index of at least 30 kg/m², diabetes mellitus, uncontrolled hypertension, known respiratory disease, heart failure or coronary disease, fever of at least 38.4° C within the last 48 hours, dyspnea at presentation, bicytopenia, pancytopenia, or the combination of high neutrophil count and low lymphocyte count.

Participants were randomly assigned to receive either placebo or colchicine 0.5 mg twice daily for 3 days and then once daily for another 27 days.

The number needed to prevent one COVID-19 complication is about 60 patients, Dr. Tardif said.

Colchicine was well tolerated and resulted in fewer serious adverse events than with placebo, he said. Diarrhea occurred more often with colchicine, but there was no increase in pneumonia. Caution should be used, however, in treating patients with severe renal disease.

Dr. Tardif said he would not prescribe colchicine to an 18-year-old COVID outpatient who doesn’t have any concomitant diseases, but would for those meeting the study protocol.

“As long as a patient appears to me to be at risk of a complication, I would prescribe it, without a doubt,” he said. “I can tell you that when we held the meeting with the DSMB Friday evening, I actually put each member on the spot and asked them: ‘If it were you – not even treating a patient, but if you had COVID today, would you take it based on the data you’ve seen?’ and all of the DSMB members said they would.

“So we’ll have that debate in the public domain when the paper is out, but I believe most physicians will use it to treat their patients.”

The trial was coordinated by the Montreal Heart Institute and funded by the government of Quebec; the U.S. National Heart, Lung, and Blood Institute; Montreal philanthropist Sophie Desmarais; and the COVID-19 Therapeutics Accelerator launched by the Bill & Melinda Gates Foundation, Wellcome, and Mastercard. CGI, Dacima, and Pharmascience of Montreal were also collaborators.

Full-dose anticoagulation was superior to low, prophylactic doses in reducing the need for vital organ support such as ventilation in moderately ill patients hospitalized for COVID-19, according to a report released Jan. 22 by the National Institutes of Health (NIH).

“This is a major advance for patients hospitalized with COVID. Full dose of anticoagulation in these non-ICU patients improved outcomes and there’s a trend toward a reduction in mortality,” Judith Hochman, MD, director of the Cardiovascular Clinical Research Center at NYU Langone Medical Center, New York, said in an interview.

“We have treatments that are improving outcomes but not as many that reduce mortality, so we’re hopeful when the full dataset comes in that will be confirmed,” she said.

The observation of increased rates of blood clots and inflammation among COVID-19 patients, which can lead to complications such as lung failure, heart attack, and stroke, has given rise to various anticoagulant treatment protocols and a need for randomized data on routinely administering increased doses of anticoagulation to hospitalized patients.

Today’s top-line findings come from three linked clinical trials – REMAP-CAP, ACTIV-4, and ATTACC – examining the safety and efficacy of full-dose anticoagulation to treat moderately ill or critically ill adults hospitalized with COVID-19 compared with a lower dose typically used to prevent blood clots in hospitalized patients.

In December 2020, all three trials paused enrollment of the critically ill subgroup after results showed that full-dose anticoagulation started in the intensive care unit (ICU) was not beneficial and may have been harmful in some patients.

Moderately ill patients with COVID-19, defined as those who did not require ICU care or organ support, made up 80% of participants at enrollment in the three trials, Dr. Hochman said.

Among more than 1,000 moderately ill patients reviewed as of the data cut with the data safety monitoring board, full doses of low molecular weight or unfractionated heparin were superior to low prophylactic doses for the primary endpoint of need for ventilation or other organ supportive interventions at 21 days after randomization.

This met the predefined threshold for 99% probability of superiority and recruitment was stopped, Dr. Hochman reported. “Obviously safety figured into this decision. The risk/benefit ratio was very clear.”

The results do not pertain to patients with a previous indication for anticoagulation, who were excluded from the trials.

Data from an additional 1,000 patients will be reviewed and the data published sometime in the next 2-3 months, she said.

With large numbers of COVID-19 patients requiring hospitalization, the outcomes could help reduce the overload on intensive care units around the world, the NIH noted.

The results also highlight the critical role of timing in the course of COVID-19.

“We believe that full anticoagulation is effective early in the disease course,” Dr. Hochman said. “Based on the results so far from these three platform trials, those that were very, very sick at the time of enrollment really didn’t benefit and we needed to have caught them at an earlier stage.

“It’s possible that the people in the ICU are just different and the minute they get sick they need the ICU; so we haven’t clearly demonstrated this time course and when to intervene, but that’s the implication of the findings.”

The question of even earlier treatment is being examined in the partner ACTIV-4B trial, which is enrolling patients with COVID-19 illness not requiring hospitalization and randomizing them to the direct oral anticoagulant apixaban or aspirin or placebo.

“It’s a very important trial and we really want to get the message out that patients should volunteer for it,” said Dr. Hochman, principal investigator of the ACTIV-4 trial.

In the United States, the ACTIV-4 trial is being led by a collaborative effort involving a number of universities, including the University of Pittsburgh and New York University.

The REMAP-CAP, ACTIV-4, and ATTACC study platforms span five continents in more than 300 hospitals and are supported by multiple international funding organizations including the National Institutes of Health, Canadian Institutes of Health Research, the National Institute for Health Research (United Kingdom), the National Health and Medical Research Council (Australia), and the PREPARE and RECOVER consortia (European Union).

Full dose of anticoagulation in these non-ICU patients improved outcomes and there’s a trend toward a reduction in mortality,” Judith Hochman, MD, director of the Cardiovascular Clinical Research Center at NYU Langone Medical Center, New York, said in an interview.

“We have treatments that are improving outcomes but not as many that reduce mortality, so we’re hopeful when the full dataset comes in that will be confirmed,” she said.

The observation of increased rates of blood clots and inflammation among COVID-19 patients, which can lead to complications such as lung failure, heart attack, and stroke, has given rise to various anticoagulant treatment protocols and a need for randomized data on routinely administering increased doses of anticoagulation to hospitalized patients.

Today’s top-line findings come from three linked clinical trials – REMAP-CAP, ACTIV-4, and ATTACC – examining the safety and efficacy of full-dose anticoagulation to treat moderately ill or critically ill adults hospitalized with COVID-19 compared with a lower dose typically used to prevent blood clots in hospitalized patients.

In December 2020, all three trials paused enrollment of the critically ill subgroup after results showed that full-dose anticoagulation started in the intensive care unit (ICU) was not beneficial and may have been harmful in some patients.

Moderately ill patients with COVID-19, defined as those who did not require ICU care or organ support, made up 80% of participants at enrollment in the three trials, Dr. Hochman said.

Among more than 1,000 moderately ill patients reviewed as of the data cut with the data safety monitoring board, full doses of low molecular weight or unfractionated heparin were superior to low prophylactic doses for the primary endpoint of need for ventilation or other organ supportive interventions at 21 days after randomization.

This met the predefined threshold for 99% probability of superiority and recruitment was stopped, Dr. Hochman reported. “Obviously safety figured into this decision. The risk/benefit ratio was very clear.”

The results do not pertain to patients with a previous indication for anticoagulation, who were excluded from the trials.

Data from an additional 1,000 patients will be reviewed and the data published sometime in the next 2-3 months, she said.

With large numbers of COVID-19 patients requiring hospitalization, the outcomes could help reduce the overload on intensive care units around the world, the NIH noted.

The results also highlight the critical role of timing in the course of COVID-19.

“We believe that full anticoagulation is effective early in the disease course,” Dr. Hochman said. “Based on the results so far from these three platform trials, those that were very, very sick at the time of enrollment really didn’t benefit and we needed to have caught them at an earlier stage.

“It’s possible that the people in the ICU are just different and the minute they get sick they need the ICU; so we haven’t clearly demonstrated this time course and when to intervene, but that’s the implication of the findings.”

The question of even earlier treatment is being examined in the partner ACTIV-4B trial, which is enrolling patients with COVID-19 illness not requiring hospitalization and randomizing them to the direct oral anticoagulant apixaban or aspirin or placebo.

“It’s a very important trial and we really want to get the message out that patients should volunteer for it,” said Dr. Hochman, principal investigator of the ACTIV-4 trial.

In the United States, the ACTIV-4 trial is being led by a collaborative effort involving a number of universities, including the University of Pittsburgh and New York University.

The REMAP-CAP, ACTIV-4, and ATTACC study platforms span five continents in more than 300 hospitals and are supported by multiple international funding organizations including the National Institutes of Health, Canadian Institutes of Health Research, the National Institute for Health Research (United Kingdom), the National Health and Medical Research Council (Australia), and the PREPARE and RECOVER consortia (European Union).

Physician burnout remains at a critical level, at 42% overall – the same percentage as last year – but COVID-19 has changed the specialties hit hardest, according to Medscape’s Death by 1,000 Cuts: Physician Burnout & Suicide Report.

Critical care physicians now top the list of those experiencing burnout, at 51%, up from 44% last year, followed by rheumatologists (50%, up from 46%) and infectious disease specialists (49%, up from 45%). Forty-nine percent of urologists reported burnout, but that was a reduction from 54% last year.

Last year, the specialties burdened most by burnout were urology, neurology, nephrology, endocrinology, and family medicine.
 

Women hit particularly hard

Women in medicine traditionally have experienced higher levels of burnout than men, and the pandemic seems to have widened that gap, with the divide now at 51% for women and 36% for men.

“Many women physicians are in families with children at home,” said Carol Bernstein, MD, psychiatrist at Montefiore Medical Center, New York. “It’s already known that women assume more responsibilities in the home than do men. The pressures have increased during COVID-19 – having to be their child’s teacher during home schooling, no child care, and the grandparents can’t babysit. In addition, all doctors and nurses are worried about bringing the virus home to their families.”

Data were collected from Aug. 30 through Nov. 5, 2020. More than 12,000 physicians from 29 specialties responded.

For many, (79%) burnout has been building over years, but for some (21%), it started with the pandemic. Factors cited include lack of adequate personal protective equipment, grief from losing patients, watching families suffer, long hours, and difficult working conditions.

More than 70% of those who responded feel that burnout has had at least a moderate impact on their lives.

“One-tenth consider it severe enough to consider leaving medicine,” survey authors wrote, “an unexpected outcome after having spent so many years in training to become a physician.”

Tragically, an estimated 300 physicians each year in the United States are consumed by the struggle and take their own lives.
 

One percent have attempted suicide

In this survey, 13% of physicians had thoughts of suicide, and 1% have attempted it; 81% said they had no thoughts of suicide; and 5% preferred not to answer.

By specialty, obstetricians/gynecologists were most likely to have thoughts of suicide (19%), followed by orthopedists (18%) and otolaryngologists and plastic surgeons (17%).

“I yell all the time, I am angry and frustrated all the time. I think about quitting all the time,” said an internist who admitted having suicidal thoughts. “No one in my organization cares about doing the right things for patients as much as I do.”

Yet, many with such thoughts tell no one. By age group, 32% of millennials, 40% of generation X physicians, and 41% of baby boomer physicians who had had thoughts of suicide said they had told no one about those thoughts.

Fear of being reported to the medical board, fear of colleagues finding out, and other factors perpetuate a cycle of burnout and depression, and most don’t seek help.

Top reasons physicians listed for not seeking help for burnout and depression include “symptoms are not severe enough” (52%); “I can deal with without help from a professional” (46%); and feeling “too busy” (40%).
 

Administrative tasks fuel burnout

The top driver of burnout continues to be “too many administrative tasks.” This year, 58% put it at the top. The next highest categories (named by 37%) were “spending too many hours at work” and “lack of respect from administrators/employers, colleagues or staff.” Others mentioned lack of control or insufficient compensation and government regulations.

Notably, only 8% said stress from treating COVID-19 patients was the top driver.

An internist said, “I’m working 6 days a week, nights, weekends, holidays!”

A general surgeon said, “Being forced to see four patients an hour when complicated patients and procedures are involved” was the biggest contributor to burnout.

One physician in the survey summarized it: “It’s all of these causes; it’s death by 1,000 cuts.”
 

Exercise tops coping list

Asked how they cope with stress and burnout, physicians put exercise at the top (48%). Next was talking with family and friends (43%), though 43% said they cope by isolating themselves.

Drinking alcohol and overeating junk food were up slightly in the past year: for alcohol, 26%, up from 24%; for junk food, 35%, up from 33%.

The action respondents said would help most to reduce burnout was “increased compensation to avoid financial stress,” chosen by 45%. Next, at 42%, was “more manageable work and schedule,” followed by greater respect from employers, colleagues, and staff (39%).

Asked whether their workplace offered programs to reduce stress and/or burnout, almost half (47%) of physicians said no; 35% said yes; and 18% didn’t know.

Participation in such programs has been low. Almost half (42%) of physicians in this survey said they would be unlikely to attend such a program. Thirty percent they would be likely to participate; 28% said they were neutral on the idea.

“Anti-stress/burnout programs focus on individual approaches to much larger problems,” Wendy K. Dean, MD, psychiatrist and president of Moral Injury of Healthcare, said in an interview. “The programs offer temporary symptomatic relief rather than lasting systemic change. Many physicians are frustrated by these approaches.”

A study last year by the Mayo Clinic found that “the most efficacious strategy to alleviate physician burnout will target organization-directed changes rather than the level of the individual.”

About 20 states across the country have detected the more transmissible B.1.1.7 SARS-CoV-2 variant to date. Given the unknowns of the emerging situation, experts with the Infectious Diseases Society of America addressed vaccine effectiveness, how well equipped the United States is to track new mutations, and shared their impressions of President Joe Biden’s COVID-19 executive orders.

One of the major concerns remains the ability of COVID-19 vaccines to work on new strains. “All of our vaccines target the spike protein and try to elicit neutralizing antibodies that bind to that protein,” Mirella Salvatore, MD, assistant professor of medicine and population health sciences at Weill Cornell Medicine, New York, said during an IDSA press briefing on Thursday.

The B.1.1.7 mutation occurs in the “very important” spike protein, a component of the SARS-CoV-2 virus necessary for binding, which allows the virus to enter cells, added Dr. Salvatore, an IDSA fellow.

The evidence suggests that SARS-CoV-2 should be capable of producing one or two mutations per month. However, the B.1.1.7 variant surprised investigators in the United Kingdom when they first discovered the strain had 17 mutations, Dr. Salvatore said.

It’s still unknown why this particular strain is more transmissible, but Dr. Salvatore speculated that the mutation gives the virus an advantage and increases binding, allowing it to enter cells more easily. She added that the mutations might have arisen among immunocompromised people infected with SARS-CoV-2, but “that is just a hypothesis.”

On a positive note, Kathryn M. Edwards, MD, another IDSA fellow, explained at the briefing that the existing vaccines target more than one location on the virus’ spike protein. Therefore, “if there is a mutation that changes one structure of the spike protein, there will be other areas where the binding can occur.”

This polyclonal response “is why the vaccine can still be effective against this virus,” added Dr. Edwards, scientific director of the Vanderbilt Vaccine Research Program and professor of pediatrics at Vanderbilt University, Nashville, Tenn.

Dr. Salvatore emphasized that, although the new variant is more transmissible, it doesn’t appear to be more lethal. “This might affect overall mortality but not for the individual who gets the infection.”
 

Staying one step ahead

When asked for assurance that COVID-19 vaccines will work against emerging variants, Dr. Edwards said, “It may be we will have to change the vaccine so it is more responsive to new variants, but at this point that does not seem to be the case.”

Should the vaccines require an update, the messenger RNA vaccines have an advantage – researchers can rapidly revise them. “All you need to do is put all the little nucleotides together,” Dr. Edwards said.

“A number of us are looking at how this will work, and we look to influenza,” she added. Dr. Edwards drew an analogy to choosing – and sometimes updating – the influenza strains each year for the annual flu vaccine. With appropriate funding, the same system could be replicated to address any evolving changes to SARS-CoV-2.

On funding, Dr. Salvatore said more money would be required to optimize the surveillance system for emerging strains in the United States.

“We actually have this system – there is a wonderful network that sequences the influenza strains,” she said. “The structure exists, we just need the funding.”

“The CDC is getting the system tooled up to get more viruses to be sequenced,” Dr. Edwards said.

Both experts praised the CDC for its website with up-to-date surveillance information on emerging strains of SARS-CoV-2.
 

President Biden’s backing of science

A reporter asked each infectious disease expert to share their impression of President Biden’s newly signed COVID-19 executive orders.

“The biggest takeaway is the role of science and the lessons we’ve learned from masks, handwashing, and distancing,” Dr. Edwards said. “We need to heed the advice ... [especially] with a variant that is more contagious.

“It is encouraging that science will be listened to – that is the overall message,” she added.

Dr. Salvatore agreed, saying that the orders give “the feeling that we can now act by following science.”

“We have plenty of papers that show the effectiveness of masking,” for example, she said. Dr. Salvatore acknowledged that there are “a lot of contrasting ideas about masking” across the United States but stressed their importance.

“We should follow measures that we know work,” she said.

Both experts said more research is needed to stay ahead of this evolving scenario. “We still need a lot of basic science showing how this virus replicates in the cell,” Dr. Salvatore said. “We need to really characterize all these mutations and their functions.”

“We need to be concerned, do follow-up studies,” she added, “but we don’t need to panic.”

Dr. Salvatore disclosed that she is a site principal investigator on a study from Verily Life Sciences/Brin Foundation on Predictors of Severe COVID-19 Outcomes and principal investigator for an investigator-initiated study sponsored by Genentech on combination therapy in influenza.

“A number of us are looking at how this will work, and we look to influenza,” she added. Dr. Edwards drew an analogy to choosing – and sometimes updating – the influenza strains each year for the annual flu vaccine. With appropriate funding, the same system could be replicated to address any evolving changes to SARS-CoV-2.

On funding, Dr. Salvatore said more money would be required to optimize the surveillance system for emerging strains in the United States.

“We actually have this system – there is a wonderful network that sequences the influenza strains,” she said. “The structure exists, we just need the funding.”

“The CDC is getting the system tooled up to get more viruses to be sequenced,” Dr. Edwards said.

Both experts praised the CDC for its website with up-to-date surveillance information on emerging strains of SARS-CoV-2.
 

President Biden’s backing of science

A reporter asked each infectious disease expert to share their impression of President Biden’s newly signed COVID-19 executive orders.

“The biggest takeaway is the role of science and the lessons we’ve learned from masks, handwashing, and distancing,” Dr. Edwards said. “We need to heed the advice ... [especially] with a variant that is more contagious.

“It is encouraging that science will be listened to – that is the overall message,” she added.

Dr. Salvatore agreed, saying that the orders give “the feeling that we can now act by following science.”

“We have plenty of papers that show the effectiveness of masking,” for example, she said. Dr. Salvatore acknowledged that there are “a lot of contrasting ideas about masking” across the United States but stressed their importance.

“We should follow measures that we know work,” she said.

Both experts said more research is needed to stay ahead of this evolving scenario. “We still need a lot of basic science showing how this virus replicates in the cell,” Dr. Salvatore said. “We need to really characterize all these mutations and their functions.”

“We need to be concerned, do follow-up studies,” she added, “but we don’t need to panic.”

This article was based on an Infectious Diseases Society of America Media Briefing on Jan. 21, 2021. Dr. Salvatore disclosed that she is a site principal investigator on a study from Verily Life Sciences/Brin Foundation on Predictors of Severe COVID-19 Outcomes and principal investigator for an investigator-initiated study sponsored by Genentech on combination therapy in influenza. Dr. Edwards disclosed National Institutes of Health and Centers for Disease Control and Prevention grants; consulting for Bionet and IBM; and being a member of data safety and monitoring committees for Sanofi, X-4 Pharma, Seqirus, Moderna, Pfizer, and Merck.

Among the many losses suffered by millions worldwide during the COVID-19 pandemic, the loss of sleep may be the most widespread, with potentially long-lasting, negative consequences on physical, mental, and emotional health, sleep researchers have found.

Results from multiple studies and surveys conducted during the pandemic show that a majority of subjects report clinically meaningful changes in sleep quality, sleep patterns, and sleep disturbances.

Sleeping, more or less

A coauthor of that study, David Gozal, MD, FCCP, a pediatric pulmonologist and sleep medicine specialist at the University of Missouri in Columbia, said that the pandemic has had paradoxical effects on sleeps patterns for many.

“At the beginning, with the initial phases of lockdown for COVID, for most of the people whose jobs were not affected and who did not lose their jobs, [for whom] there was not the anxiety of being jobless and financially strapped, but who now were staying at home, there was actually a benefit. People started reporting getting more sleep and, more importantly, more vivid dreams and things of that nature,” he said in an interview.

“But as the lockdown progressed, we saw progressively and increasingly more people having difficulty falling asleep and staying asleep, using more medicines such as hypnotics to induce sleep, and we saw a 20% increase in the overall consumption of sleeping pills,” he said.

Similar results were seen in a cross-sectional survey of 843 adults in the United Kingdom, which showed that nearly 70% of participants reported a change in sleep patterns, only 45% reported having refreshing sleep, and 46% reported being sleepier during lockdown than before. Two-thirds of the respondents reported that the pandemic affected their mental health, and one-fourth reported increased alcohol consumption during lockdown. Those with suspected COVID-19 infections reported having more nightmares and abnormal sleep rhythms.

It is possible that the effects of COVID-19 infection on sleep may linger long after the infection itself has resolved, results of a cohort study from China suggest. As reported in The Lancet, among 1,655 patients discharged from the Jin Yin-tan hospital in Wuhan, 26% reported sleep disturbances 6 months after acute COVID-19 infection.
 

Self-medicating

Among 5,525 Canadians surveyed from April 3 through June 24, 2020, a large proportion reported the use of pharmacologic sleeps aids, said Tetyana Kendzerska, MD, PhD, assistant professor of medicine in the division of respirology at the University of Ottawa.

“At the time of the survey completion, 27% of participants reported taking sleeping aids (prescribed or [over] the counter); across the entire sample, 8% of respondents reported an increase in the frequency of sleeping medication use during the outbreak compared to before the outbreak,” she said in an interview.

Many people resort to self-medicating with over-the-counter preparations such as melatonin and pain-relief nighttime formulations containing diphenhydramine (Benadryl), a first-generation antihistamine with sedative properties, noted Kannan Ramar, MBBS, MD, a critical care, pulmonary, and sleep medicine specialist at the Mayo Clinic in Rochester, Minn., and current president of the American Academy of Sleep Medicine.

“When people are self-medicating for what they think is difficulty sleeping, the concern is that even if a diagnosis of insomnia has been established, there could be another, ongoing sleep disorder that may be undiagnosed, which might be causing the problem with insomnia,” he said in an interview.

“For example, obstructive sleep apnea might be causing people to wake up in the night or even contribute to difficulty falling asleep in the first place. So medicating for something without a known diagnosis may leave an underlying sleep disorder untreated, which won’t help the patient in either the short or the long term,” Dr. Ramar said.
 

Causes for concern

“For those people who have COVID, we have seen quite a few sleep issues develop. Those were not reported in the actual study, but in the clinic and subsequent studies published from other places,” Dr. Gozal said.

“People who suffered from COVID, and even people who supposedly did very well and were virtually asymptomatic or maybe had only a headache or fever but did not need to go to the hospital, many of those people reported either excessive sleepiness for a long period of time, and would sleep 2 or 3 hours more per night. Or the opposite was reported: There were those that after recovering reported that they couldn’t sleep – they were sleeping 4 or 5 hours when they normally sleep 7 or 8,” he said.

It’s also unclear from current evidence whether the reported uptick in sleep problems is related to stress or, in patients who have had COVID-19 infections, to physiologic causes.

Dr. Gozal said that insomnia in the time of COVID-19 could be attributed to a number of factors such as less daily exposure to natural light from people sheltering indoors, stress related to financial or health worries, depression, or other psychological factors.

It’s also, possible, however, that COVID-19-related physiological changes could contribute to sleep disorders, he said, pointing to a recent study in the Journal of Experimental Medicine showing that SARS-CoV-2, the virus that causes COVID-19, can bind to neurons and cause metabolic changes in both infected and neighboring cells.

“My guess is that some of it is related more to behavioral impacts – people develop depression, changes in mood, anxiety, and so on, and all of these can translate into difficulties with sleep,” he said.

“It could be that in some instances – not very commonly – the virus will affect areas that control sleep in our brain, and that therefore we may see too much or too little sleep, and how to differentiate between all of these is the area that clearly needs to be explored, particularly in light of the finding that the virus can bind to brain cells and can induce substantial issues in the brain cells.”
 

Compromised immunity

It has been well documented that in addition to being, as Shakespeare called it, “the balm of hurt minds,” sleep has an important role in supporting the immune system.

“Sleep and immunity go together,” Dr. Ramar said. “When people have adequate sleep, their immune system is boosted. We know that there are good data from hepatitis A and hepatitis B vaccinations, and recently on flu vaccination, that if people get sufficient duration of sleep before and after they receive the shot, their likelihood of building an immune response to that particular vaccination tends to go up.”

It’s reasonable to assume that the same would hold true for COVID-19 vaccinations, but this has yet to be shown, he added.

“We do know from the previous studies that persistent sleep problems can make people more susceptible to infection or impair recovery; not yet, I believe, from the COVID-19 infection perspective,” Dr. Kendzerska said. “In our study, we did find that, among other factors, having a chronic illness was associated with new sleep difficulties during the pandemic. We did not look separately if sleep difficulties were associated with the COVID-19 infection or symptoms, but this is a great question to address with longitudinal data we have.”
 

What to do?

All three sleep experts contacted for this article agreed that for patients with insomnia, mitigating stress through relaxation techniques or cognitive behavioral therapy is more beneficial than medication.

“Medications, even over-the-counter medications, all have side effects, and if one is taking a medication that has stimulants in place, such as pseudoephedrine in antihistamine combinations, that can potentially contribute to or exacerbate any underlying sleep disorders,” Dr. Ramar said.

Dr. Kendzerska recommended reserving medications such as melatonin, a chronobiotic therapy, for patients with sleep disorders related to circadian rhythm problems, including a sleep phase delay. Supplemental, short-term treatment with hypnotic agents such as zolpidem (Ambien), eszopiclone (Lunesta), or zaleplon (Sonata) should be used only as a last resort, she said.

Sleep medicine specialists recommend good sleep hygiene as the best means of obtaining restful sleep, including regular bed and wake times, limited exposure to stressful news (including COVID-19 stories), reduced consumption of alcohol and stimulants such as coffee or caffeine drinks, avoiding use of electronic devices in bed or near bedtime, and healthy lifestyle, including diet and exercise.

They also frown on self-medication with over-the-counter aids, because these products may not be addressing the underlying issue, as noted before.

“It is also foreseeable that there may be an increase in individuals who may require professional guidance to taper off from sleeping medications started or increased during the pandemic. While some of these sleep problems may be transient, it should be a high priority to ensure they do not evolve into chronic sleep disorders,” Dr. Kendzerska and colleagues wrote.
 

Research avenues

If there’s anything that causes specialists to lose sleep, it’s the lack of data or evidence to guide clinical care and research. Dr. Gozal emphasized that little is still known about the potential central nervous system effects of COVID-19, and said that should be an important focus for research into the still novel coronavirus.

“What happens post COVID and how might that affect subsequent recovery is a great question, and I don’t think we have good data there,” Dr. Ramar said. “What we do know is that patients develop the symptoms of fatigue, disrupted sleep, even ongoing fever, and unfortunately, this may persist for a long period of time even among patients who have otherwise recovered from COVID-19. We know that leaving that untreated from a sleep disorder perspective can exacerbate their daytime symptoms, and that’s where I would strongly recommend that they seek help with a sleep provider or if there are symptoms other than insomnia at least with a primary care provider.”

A combination treatment of neutralizing monoclonal antibodies bamlanivimab and etesevimab was associated with a statistically significant reduction in SARS-CoV-2 at day 11 compared with placebo among nonhospitalized patients who had mild to moderate COVID-19, new data indicate.

However, bamlanivimab alone in three different single-infusion doses showed no significant reduction in viral load, compared with placebo, according to the phase 2/3 study by Robert L. Gottlieb, MD, PhD, of the Baylor University Medical Center and the Baylor Scott & White Research Institute, both in Dallas, and colleagues.

Findings from the Blocking Viral Attachment and Cell Entry with SARS-CoV-2 Neutralizing Antibodies (BLAZE-1) study were published online Jan. 21 in JAMA. The results represent findings through Oct. 6, 2020.

BLAZE-1 was funded by Eli Lilly, which makes both of the antispike neutralizing antibodies. The trial was conducted at 49 U.S. centers and included 613 outpatients who tested positive for SARS-CoV-2 and had one or more mild to moderate symptoms.

Patients were randomized to one of five groups (four treatment groups and a placebo control), and researchers analyzed between-group differences.

All four treatment arms suggest a trend toward reduction in viral load, which was the primary endpoint of the trial, but only the combination showed a statistically significant reduction.

The average age of patients was 44.7 years, 54.6% were female, 42.5% were Hispanic, and 67.1% had at least one risk factor for severe COVID-19 (aged ≥55 years, body mass index of at least 30, or relevant comorbidity such as hypertension).

Among secondary outcomes, there were no consistent differences between the monotherapy groups or the combination group versus placebo for the other measures of viral load or clinical symptom scores.

The proportion of patients who had COVID-19–related hospitalizations or ED visits was 5.8% (nine events) for placebo; 1.0% (one event) for the 700-mg group; 1.9% (two events) for 2,800 mg; 2.0% (two events) for 7,000 mg; and 0.9% (one event) for combination treatment.

“Combining these two neutralizing monoclonal antibodies in clinical use may enhance viral load reduction and decrease treatment-emergent resistant variants,” the authors concluded.
 

Safety profile comparison

As for adverse events, immediate hypersensitivity reactions were reported in nine patients (six bamlanivimab, two combination treatment, and one placebo). No deaths occurred during the study.

Serious adverse events unrelated to SARS-CoV-2 infection or considered related to the study drug occurred in 0% (0/309) of patients in the bamlanivimab monotherapy groups; in 0.9% (1/112) of patients in the combination group; and in 0.6% (1/156) of patients in the placebo group.

The serious adverse event in the combination group was a urinary tract infection deemed unrelated to the study drug, the authors wrote.

The two most frequently reported side effects were nausea (3.0% for the 700-mg group; 3.7% for the 2,800-mg group; 5.0% for the 7,000-mg group; 3.6% for the combination group; and 3.8% for the placebo group) and diarrhea (1.0%, 1.9%, 5.9%, 0.9%, and 4.5%, respectively).

The authors included in the study’s limitations that the primary endpoint at day 11 may have been too late to best detect treatment effects.

“All patients, including those who received placebo, demonstrated substantial viral reduction by day 11,” they noted. “An earlier time point like day 3 or day 7 could possibly have been more appropriate to measure viral load.”

Currently, only remdesivir has been approved by the Food and Drug Administration for treating COVID-19, but convalescent plasma and neutralizing monoclonal antibodies have been granted emergency-use authorization.

In an accompanying editor’s note, Preeti N. Malani, MD, with the division of infectious diseases at the University of Michigan, Ann Arbor, and associate editor of JAMA, and Robert M. Golub, MD, deputy editor of JAMA, pointed out that these results differ from an earlier interim analysis of BLAZE-1 data.

A previous publication by Peter Chen, MD, with the department of medicine at Cedars Sinai Medical Center, Los Angeles, compared the three monotherapy groups (no combination group) with placebo, and in that study the 2,800-mg dose of bamlanivimab versus placebo achieved statistical significance for reduction in viral load from baseline at day 11, whereas the other two doses did not.

The editors explain that, in the study by Dr. Chen, “Follow-up for the placebo group was incomplete at the time of the database lock on Sept. 5, 2020. In the final analysis reported in the current article, the database was locked on Oct. 6, 2020, and the longer follow-up for the placebo group, which is now complete, resulted in changes in the primary outcome among that group.”

They concluded: “The comparison of the monotherapy groups against the final results for the placebo group led to changes in the effect sizes,” and the statistical significance of the 2,800-mg group was erased.

The editors pointed out that monoclonal antibodies are likely to benefit certain patients but definitive answers regarding which patients will benefit and under what circumstances will likely take more time than clinicians have to make decisions on treatment.

Meanwhile, as this news organization reported, the United States has spent $375 million on bamlanivimab and $450 million on Regeneron’s monoclonal antibody cocktail of casirivimab plus imdevimab, with the promise to spend billions more.

However, 80% of the 660,000 doses delivered by the two companies are still sitting on shelves, federal officials said in a press briefing last week, because of doubts about efficacy, lack of resources for infusion centers, and questions on reimbursement.

“While the world waits for widespread administration of effective vaccines and additional data on treatments, local efforts should work to improve testing access and turnaround time and reduce logistical barriers to ensure that monoclonal therapies can be provided to patients who are most likely to benefit,” Dr. Malani and Dr. Golub wrote.

This trial was sponsored and funded by Eli Lilly. Dr. Gottlieb disclosed personal fees and nonfinancial support (medication for another trial) from Gilead Sciences and serving on an advisory board for Sentinel. Several coauthors have financial ties to Eli Lilly. Dr. Malani reported serving on the National Institute of Allergy and Infectious Diseases COVID-19 Preventive Monoclonal Antibody data and safety monitoring board but was not compensated. Dr. Golub disclosed no relevant financial relationships.

A combination treatment of neutralizing monoclonal antibodies bamlanivimab and etesevimab was associated with a statistically significant reduction in SARS-CoV-2 at day 11 compared with placebo among nonhospitalized patients who had mild to moderate COVID-19, new data indicate.

However, bamlanivimab alone in three different single-infusion doses showed no significant reduction in viral load, compared with placebo, according to the phase 2/3 study by Robert L. Gottlieb, MD, PhD, of the Baylor University Medical Center and the Baylor Scott & White Research Institute, both in Dallas, and colleagues.

Findings from the Blocking Viral Attachment and Cell Entry with SARS-CoV-2 Neutralizing Antibodies (BLAZE-1) study were published online Jan. 21 in JAMA. The results represent findings through Oct. 6, 2020.

BLAZE-1 was funded by Eli Lilly, which makes both of the antispike neutralizing antibodies. The trial was conducted at 49 U.S. centers and included 613 outpatients who tested positive for SARS-CoV-2 and had one or more mild to moderate symptoms.

Patients were randomized to one of five groups (four treatment groups and a placebo control), and researchers analyzed between-group differences.

All four treatment arms suggest a trend toward reduction in viral load, which was the primary endpoint of the trial, but only the combination showed a statistically significant reduction.

The average age of patients was 44.7 years, 54.6% were female, 42.5% were Hispanic, and 67.1% had at least one risk factor for severe COVID-19 (aged ≥55 years, body mass index of at least 30, or relevant comorbidity such as hypertension).

Among secondary outcomes, there were no consistent differences between the monotherapy groups or the combination group versus placebo for the other measures of viral load or clinical symptom scores.

The proportion of patients who had COVID-19–related hospitalizations or ED visits was 5.8% (nine events) for placebo; 1.0% (one event) for the 700-mg group; 1.9% (two events) for 2,800 mg; 2.0% (two events) for 7,000 mg; and 0.9% (one event) for combination treatment.

“Combining these two neutralizing monoclonal antibodies in clinical use may enhance viral load reduction and decrease treatment-emergent resistant variants,” the authors concluded.
 

Safety profile comparison

As for adverse events, immediate hypersensitivity reactions were reported in nine patients (six bamlanivimab, two combination treatment, and one placebo). No deaths occurred during the study.

Serious adverse events unrelated to SARS-CoV-2 infection or considered related to the study drug occurred in 0% (0/309) of patients in the bamlanivimab monotherapy groups; in 0.9% (1/112) of patients in the combination group; and in 0.6% (1/156) of patients in the placebo group.

The serious adverse event in the combination group was a urinary tract infection deemed unrelated to the study drug, the authors wrote.

The two most frequently reported side effects were nausea (3.0% for the 700-mg group; 3.7% for the 2,800-mg group; 5.0% for the 7,000-mg group; 3.6% for the combination group; and 3.8% for the placebo group) and diarrhea (1.0%, 1.9%, 5.9%, 0.9%, and 4.5%, respectively).

The authors included in the study’s limitations that the primary endpoint at day 11 may have been too late to best detect treatment effects.

“All patients, including those who received placebo, demonstrated substantial viral reduction by day 11,” they noted. “An earlier time point like day 3 or day 7 could possibly have been more appropriate to measure viral load.”

Currently, only remdesivir has been approved by the Food and Drug Administration for treating COVID-19, but convalescent plasma and neutralizing monoclonal antibodies have been granted emergency-use authorization.
