Plagued by false starts, a few dashed hopes, but with perhaps a glimmer of light on the horizon, the race to find an effective treatment for COVID-19 continues. At last count, more than 300 treatments and 200 vaccines were in preclinical or clinical development (not to mention the numerous existing agents that are being evaluated for repurposing).

There is also a renewed interest in cannabinoid therapeutics — in particular, the nonpsychoactive agent cannabidiol (CBD) and the prospect of its modulating inflammatory and other disease-associated clinical indices, including SARS-CoV-2–induced viral load, hyperinflammation, the cytokine storm, and acute respiratory distress syndrome (ARDS).

Long hobbled by regulatory, political, and financial barriers, CBD’s potential ability to knock back COVID-19–related inflammation might just open doors that have been closed for years to CBD researchers.
 

Why CBD and why now?

CBD and the resulting therapeutics have been plagued by a complicated association with recreational cannabis use. It’s been just 2 years since CBD-based therapeutics moved into mainstream medicine — the US Food and Drug Administration (FDA) approved Epidiolex oral solution for the treatment of Lennox-Gastaut syndrome and Dravet syndrome, and in August, the FDA approved it for tuberous sclerosis complex.

CBD’s mechanism of action has not been fully elucidated, but on the basis of its role in immune responses — well described in research spanning more than two decades — it›s not surprising that cannabinoid researchers have thrown their hats into the COVID-19 drug development ring.

The anti-inflammatory potential of CBD is substantial and appears to be related to the fact that it shares 20 protein targets common to inflammation-related pathways, Jenny Wilkerson, PhD, research assistant professor at the University of Florida School of Pharmacy, Gainesville, Florida, explained to Medscape Medical News.

Among the various trials that are currently recruiting or are underway is one that is slated for completion this fall. CANDIDATE (Cannabidiol for COVID-19 Patients With Mild-to-Moderate COVID-19) is a randomized, controlled, double-blind study led by Brazilian researchers at the University of São Paulo. The study, which began recruitment this past August, enrolled 100 patients, 50 in the active treatment group (who received capsulated CBD 300 mg daily for 14 days plus pharmacologic therapy [antipyretics] and clinical measures) and 50 who received placebo.

The primary outcome is intended to help clarify the potential role of oral CBD for preventing COVID-19 disease progression, modifying disease-associated clinical indices, and modulating inflammatory parameters, such as the cytokine storm, according to lead investigator Jose Alexandre de Souza Crippa, MD, PhD, professor of neuropsychology at the Ribeirao Preto Medical School at the University of São Paulo in Brazil, in the description of the study on clinicaltrials.gov. Crippa declined to provide any additional information about the trial in an email to Medscape Medical News.
 

Calming or preventing the storm

While Crippa and colleagues wrap up their CBD trial in South America, several North American and Canadian researchers are seeking to clarify and address one of the most therapeutically challenging aspects of SARS-CoV-2 infection — the lung macrophage–orchestrated hyperinflammatory response.

Although hyperinflammation is not unique to SARS-CoV-2 infection, disease severity and COVID-19–related mortality have been linked to this rapid and prolonged surge of inflammatory cytokines (eg, interleukin 6 [IL-6], IL-10, tumor necrosis factors [TNF], and chemokines) and the cytokine storm.

“When you stimulate CB2 receptors (involved in fighting inflammation), you get a release of the same inflammatory cytokines that are involved in COVID,” Cecilia Costiniuk, MD, associate professor and researcher at the Research Institute of the McGill University Health Center, Montreal, Canada, told Medscape Medical News.

“So, if you can act on this receptor, you might be able to reduce the release of those damaging cytokines that are causing ARDS, lung damage, etc,” she explained. Targeting these inflammatory mediators has been a key strategy in research aimed at reducing COVID-19 severity and related mortality, which is where CBD comes into play.

“CBD is a very powerful immune regulator. It keeps the [immune] engine on, but it doesn’t push the gas pedal, and it doesn’t push the brake completely,” Babak Baban, PhD, professor and immunologist at the Dental College of Georgia at Augusta University, told Medscape Medical News.

To explore the effectiveness of CBD in reducing hyperactivated inflammatory reactions, Baban and colleagues examined the potential of CBD to ameliorate ARDS in a murine model. The group divided wild-type male mice into sham, control, and treatment groups.

The sham group received intranasal phosphate buffered saline; the treatment and control groups received a polyriboinosinic:polycytidylic acid (poly I:C) double-stranded RNA analogue (100 mcg daily for 3 days) to simulate the cytokine storm and clinical ARDS symptoms.

Following the second poly I:C dose, the treatment group received CBD 5 mg/kg intraperitoneally every other day for 6 days. The mice were sacrificed on day 8.

The study results, published in July in Cannabis and Cannabinoid Research, first confirmed that the poly I:C model simulated the cytokine storm in ARDS, reducing blood oxygen saturation by as much as 10% (from ±81.6% to ±72.2%).

Intraperitoneally administered CBD appeared to reverse these ARDS-like trends. “We observed a significant improvement in severe lymphopenia, a mild decline in the ratio of neutrophils to T cells, and significant reductions in levels of [inflammatory and immune factors] IL-6, IFN-gamma [interferon gamma], and in TNF-alpha after the second CBD dose,” Baban said.

There was also a marked downregulation in infiltrating neutrophils and macrophages in the lung, leading to partial restoration of lung morphology and structure. The investigators write that this suggests “a counter inflammatory role for CBD to limit ARDS progression.”

Additional findings from a follow-up study published in mid-October “provide strong data that CBD may partially assert its beneficial and protective impact through its regulation of the apelin peptide,” wrote Baban in an email to Medscape Medical News.

“Apelin may also be a reliable biomarker for early diagnosis of ARDS in general, and in COVID-19 in particular,” he wrote.

Questions remain concerning dose response and whether CBD alone or in combination with other phytocannabinoids is more effective for treating COVID-19. Timing is likewise unclear.

Baban explained that as a result of the biphasic nature of COVID-19, the “sweet spot” appears to be just before the innate immune response progresses into an inflammation-driven response and fibrotic lung damage occurs.

But Wilkerson isn’t as convinced. She said that as with a thermostat, the endocannabinoid system needs tweaking to get it in the right place, that is, to achieve immune homeostasis. The COVID cytokine storm is highly unpredictable, she added, saying, “Right now, the timing for controlling the COVID cytokine storm is really a moving target.”
 

Is safety a concern?

Safety questions are expected to arise, especially in relation to COVID-19. CBD is not risk free, and one size does not fit all. Human CBD studies report gastrointestinal and somnolent effects, as well as drug-drug interactions.

Findings from a recent systematic review of randomized, controlled CBD trials support overall tolerability, suggesting that serious adverse events are rare. Such events are believed to be related to drug-drug interactions rather than to CBD itself. On the flip side, it is nonintoxicating, and there does not appear to be potential for abuse.

“It’s generally well tolerated,” Wilkerson said. “There’ve now been several clinical trials in numerous patient population settings where basically the only time you really start to have issues is where you have patients on very select agents. But this is where a pharmacist would come into play.”

Costiniuk agreed: “Just because it’s cannabis, it doesn’t mean that there’s going to be strange or unusual effects; these people [ie, those with severe COVID-19] are in the hospital and monitored very closely.”
 

Delving into the weeds: What’s next?

Although non-COVID-19 cannabinoid researchers have encountered regulatory roadblocks, several research groups that have had the prescience to dive in at the right time are gaining momentum.

Baban’s team has connected with one of the nation’s few academic laboratories authorized to work with the SARS-CoV-2 virus and are awaiting protocol approval so that they can reproduce their research, this time using two CBD formulations (injectable and inhaled).

If findings are positive, they will move forward quickly to meet with the FDA, Baban said, adding that the team is also collaborating with two organizations to conduct human clinical trials in hopes of pushing up timing.

The initial article caught the eye of the World Health Organization, which included it in its global literature on the coronavirus resource section.

Israeli researchers have also been quite busy. InnoCan Pharma and Tel Aviv University are collaborating to explore the potential for CBD-loaded exosomes (minute extracellular particles that mediate intracellular communication, including via innate and adaptive immune responses). The group plans to use these loaded exosomes to target and facilitate recovery of COVID-19–damaged lung cells.

From a broader perspective, the prospects for harnessing cannabinoids for immune modulation will be more thoroughly explored in a special issue of Cannabis and Cannabinoid Research, which has extended its current call for papers, studies, abstracts, and conference proceedings until the end of December.

Like many of the therapeutic strategies under investigation for the treatment of COVID-19, studies in CBD may continue to raise more questions than answers.

Still, Wilkerson is optimistic. “Taken together, these studies along with countless others suggest that the complex pharmacophore of Cannabis sativa may hold therapeutic utility to treat lung inflammation, such as what is seen in a COVID-19 cytokine storm,» she told Medscape Medical News. “I’m very excited to see what comes out of the research.”

Baban, Wilkerson, and Costiniuk have disclosed no relevant financial relationships.

There were more new cases of COVID-19 reported in children during the week ending Oct. 29 than any other week during the pandemic, the American Academy of Pediatrics announced Nov. 2.

For the week, over 61,000 cases were reported in children, bringing the number of COVID-19 cases for the month of October to nearly 200,000 and the total since the start of the pandemic to over 853,000, the AAP and the Children’s Hospital Association said in their weekly report.

“These numbers reflect a disturbing increase in cases throughout most of the United States in all populations, especially among young adults,” Yvonne Maldonado, MD, chair of the AAP Committee on Infectious Diseases, said in a separate statement. “We are entering a heightened wave of infections around the country. We would encourage family holiday gatherings to be avoided if possible, especially if there are high-risk individuals in the household.”

For the week ending Oct. 29, children represented 13.3% of all cases, possibly constituting a minitrend of stability over the past 3 weeks. For the full length of the pandemic, 11.1% of all COVID-19 cases have occurred in children, although severe illness is much less common: 1.7% of all hospitalizations (data from 24 states and New York City) and 0.06% of all deaths (data from 42 states and New York City), the AAP and CHA report said.

Other data show that 1,134 per 100,000 children in the United States have been infected by the coronavirus, up from 1,053 the previous week, with state rates ranging from 221 per 100,000 in Vermont to 3,321 in North Dakota. In Wyoming, 25.5% of all COVID-19 cases have occurred in children, the highest of any state, while New Jersey has the lowest rate at 4.9%, the AAP/CHA report showed.

In the 10 states making testing data available, children represent the lowest percentage of tests in Iowa (5.0%) and the highest in Indiana (16.9%). Iowa, however, has the highest positivity rate for children at 14.6%, along with Nevada, while West Virginia has the lowest at 3.6%, the AAP and CHA said in the report.

These numbers, however, may not be telling the whole story. “The number of reported COVID-19 cases in children is likely an undercount because children’s symptoms are often mild and they may not be tested for every illness,” the AAP said in its statement.

“We urge policy makers to listen to doctors and public health experts rather than level baseless accusations against them. Physicians, nurses and other health care professionals have put their lives on the line to protect our communities. We can all do our part to protect them, and our communities, by wearing masks, practicing physical distancing, and getting our flu immunizations,” AAP President Sally Goza, MD, said in the AAP statement.

These numbers, however, may not be telling the whole story. “The number of reported COVID-19 cases in children is likely an undercount because children’s symptoms are often mild and they may not be tested for every illness,” the AAP said in its statement.

“We urge policy makers to listen to doctors and public health experts rather than level baseless accusations against them. Physicians, nurses and other health care professionals have put their lives on the line to protect our communities. We can all do our part to protect them, and our communities, by wearing masks, practicing physical distancing, and getting our flu immunizations,” AAP President Sally Goza, MD, said in the AAP statement.

There were more new cases of COVID-19 reported in children during the week ending Oct. 29 than any other week during the pandemic, the American Academy of Pediatrics announced Nov. 2.

For the week, over 61,000 cases were reported in children, bringing the number of COVID-19 cases for the month of October to nearly 200,000 and the total since the start of the pandemic to over 853,000, the AAP and the Children’s Hospital Association said in their weekly report.

“These numbers reflect a disturbing increase in cases throughout most of the United States in all populations, especially among young adults,” Yvonne Maldonado, MD, chair of the AAP Committee on Infectious Diseases, said in a separate statement. “We are entering a heightened wave of infections around the country. We would encourage family holiday gatherings to be avoided if possible, especially if there are high-risk individuals in the household.”

For the week ending Oct. 29, children represented 13.3% of all cases, possibly constituting a minitrend of stability over the past 3 weeks. For the full length of the pandemic, 11.1% of all COVID-19 cases have occurred in children, although severe illness is much less common: 1.7% of all hospitalizations (data from 24 states and New York City) and 0.06% of all deaths (data from 42 states and New York City), the AAP and CHA report said.

Other data show that 1,134 per 100,000 children in the United States have been infected by the coronavirus, up from 1,053 the previous week, with state rates ranging from 221 per 100,000 in Vermont to 3,321 in North Dakota. In Wyoming, 25.5% of all COVID-19 cases have occurred in children, the highest of any state, while New Jersey has the lowest rate at 4.9%, the AAP/CHA report showed.

In the 10 states making testing data available, children represent the lowest percentage of tests in Iowa (5.0%) and the highest in Indiana (16.9%). Iowa, however, has the highest positivity rate for children at 14.6%, along with Nevada, while West Virginia has the lowest at 3.6%, the AAP and CHA said in the report.

A gel derived from birch bark is the first topical medication ever tested in the treatment of epidermolysis bullosa (EB) to heal wounds faster than placebo. The results come from the largest double-blind, randomized trial performed in this patient population.

Dr. Dedee Murrell

More than 41% of EB target wounds that were treated with Oleogel-S10 healed within 45 days, compared with about 29% of target wounds treated with placebo, in the EASE phase 3 trial, conducted at 58 sites in 28 countries.

A group of rare genetic disorders, EB “is described as the worst disease you’ve never heard of,” explained lead investigator Dedee Murrell, MD, director of dermatology, St. George Hospital at the University of New South Wales, Sydney. “It starts in children and is like having burns that heal with scars, and no treatment has been approved for it” by the Food and Drug Administration.

“This is the first large clinical trial with placebo of a topical treatment that’s worked for this terrible disease,” Dr. Murrell said in an interview. She noted that standard EB treatment currently consists of applying nonstick dressings to wounds to protect skin from trauma and infection.

Dr. Murrell, who has focused her work on EB patients since 1990, presented the findings at the virtual annual Congress of the European Academy of Dermatology and Venereology.

The trial enrolled 223 patients (average age, 12 years, but ages ranged to 81 years) with three types of EB, including dystrophic and junctional EB and Kindler syndrome. For each participant, a target wound was selected for use as the primary efficacy endpoint. Those wounds had a partial thickness of between 10 cm² and 50 cm² and lasted between 21 days and 9 months. Patients were stratified into groups depending on type of EB and size of target wound.

Participants were randomly assigned to receive either Oleogel-S10 (n = 109) or placebo (n = 114). All applied the blinded-study gel to all their wounds at least every 4 days at the time dressings were changed.

The primary endpoint was the percentage of patients whose target wounds completely closed within 45 days. Key secondary endpoints included time to wound healing and percentage of target wounds that healed within 90 days of treatment; incidence and severity of target wound infection; change in total body wound burden, as measured by the Epidermolysis Bullosa Disease Activity and Scarring Index skin activity subscore; change in itching, as measured by the Itch Man Scale and the Leuven Itch Scale; and adverse events.

Nearly 92% of patients who were treated with Oleogel-S10 completed the double-blind phase of the trial, compared with nearly 87% who received placebo. As noted, the primary endpoint was met, with 41.3% of Oleogel-S10 patients achieving target wound closure within 45 days, compared with 28.9% of the patients who received placebo (P = .013).

But the difference in time to wound healing by day 90 between the two patient groups was not statistically significant (P = .302), with 50.5% of Oleogel-S10 patients achieving wound closure vs. 43.9% of control patients.

Target-wound infection occurred in eight participants, including three who used Oleogel-S10 and five who received placebo; all moderate or severe infections occurred in patients who received placebo. Total wound burden was reduced to a greater extent among Oleogel-S10 patients by day 60, but there was no apparent difference at day 90.

Both treatment groups reported qualitative improvements in itch, with no significant differences between groups. The prevalence of adverse events was also similar between groups (Oleogel-S10, 81.7%; placebo, 80.7%). The most frequently reported adverse events among Oleogel-S10 patients, compared with patients who received placebo, were wound complications, pyrexia, wound infection, pruritus, and anemia; only 4.5% of adverse events were deemed severe.

Dr. Murrell said that, on the basis of the trial results, she expects the FDA to fast-track approval of Oleogel-S10, which contains triterpene extract and sunflower oil.

The gel is “a treatment patients will be able to put under their dressings, added to normal treatment, which will accelerate their wound healing, with no significant increase in any side effects,” she added.

Jemima Mellerio, MD, of St. Thomas’ Hospital in London who sees about 400 EB patients each year, agreed with Dr. Murrell that the results are “very exciting.” Dr. Mellerio was not involved in the study.

“Practicing dermatologists seeing people with EB will have something to offer that appears to speed up wound healing in chronic wounds,” Dr. Mellerio said in an interview. “It’s a positive option rather than just supportive treatment, something that makes a difference to the natural history of wounds.”

She said the trial’s biggest strength was including “such a large cohort of patients.

“It’s extremely difficult to do that kind of study, especially with a placebo-controlled arm and especially in a rare disease,” Dr. Mellerio said. “If you think about the product itself, it’s easy to apply, so it’s not particularly onerous for people to add to their daily regimen of dressings.”

The study was funded by Amryt Pharma. Dr. Murrell is an advisory board member for Amryt Pharma. Dr. Mellerio is a consultant for Amryt Pharma.

Choosing the most effective treatment for patients with obsessive-compulsive disorder requires flexibility and agility on the part of clinicians, according to Wayne K. Goodman, MD.

“There are no data at this point to suggest that one SSRI is superior to another. It’s really dealer’s choice, and it has to do with really picking medications based upon side effects,” Dr. Goodman said at the Psychopharmacology Update, presented by Current Psychiatry and Global Academy for Medical Education. Clinicians can use family history as a guide, he noted, but pharmacogenetic testing has not been helpful in his experience for selection or dosing of an SSRI.

SSRIs, such as fluvoxamine, are one of two mainstays of treatment for patients with obsessive-compulsive disorder (OCD). The other drug class is serotonin reuptake inhibitors, which include medications such clomipramine. Cognitive-behavioral therapy options, such as Exposure and Response Prevention therapy, also has some, albeit limited, efficacy.

Meanwhile, Dr. Goodman said, antidepressant classes other than SRIs and SSRIs have not been effective in treating obsessive-compulsive symptoms, and some patients do not adhere well to cognitive-behavioral therapy, said Dr. Goodman, who is the D.C. and Irene Ellwood Professor in the department of psychiatry and behavioral sciences at Baylor College of Medicine, Houston.

Chimeric antigen receptor natural killer T (CAR NKT) cells can expand in vivo and localize to tumors in patients with relapsed/refractory neuroblastoma, according to results of an ongoing phase 1 trial.

In one of three patients treated thus far, the CAR NKT cells induced an objective response with regression of a metastatic bone lesion.

Andras Heczey, MD, of Baylor College of Medicine, Houston, and colleagues reported outcomes for the first three patients in Nature Medicine.

The three boys – two 12-year-olds and one 6-year-old – had relapsed/refractory neuroblastoma.

NKT cells were collected from the patients, then genetically engineered to express a CAR to recognize the GD2-ganglioside expressed in neuroblastomas and also to express interleukin-15, which supports NKT cell survival. The cells were expanded and reinfused back into the patients.

The initial results suggest that CAR NKT cells can be used safely to treat neuroblastomas and perhaps other solid tumors, investigators said.
 

‘A significant advance’ if confirmed

Treating solid tumors with CAR T cells has been a challenge, in part because of inefficient trafficking into tumors.

However, NKT cells naturally migrate to tumors in response to tumor-derived chemokines, Dr. Heczey and colleagues noted. NKT cells kill macrophages associated with tumor growth and promote NK- and T-cell–mediated antitumor responses.

“We decided to leverage this intrinsic property of NKTs and to arm them with an additional bullet – the so-called CAR – to further potentiate their capacity to destroy the tumor,” investigator Gianpietro Dotti, MD, of the University of North Carolina Lindberger Comprehensive Cancer Center in Chapel Hill, said in a press release.

Overall, the “results are very encouraging and, if confirmed in a larger cohort of patients, present a significant advance in the cell therapy field for solid tumors,” said CAR-T researcher Stephen Gottschalk, MD, of St. Jude Children’s Research Hospital in Memphis, Tenn., when asked for comment.
 

Treatment, safety, and efficacy details

NKT cells are infrequent in human peripheral blood, so the investigators stimulated the NKT cells collected from patients with alpha-galactosylceramide–pulsed irradiated peripheral blood mononuclear cells.

The final products reached a mean NKT cell purity of 95%. The proportion of cells positive for the GD2-CAR ranged from 20% to 70% across the three patients.

After lymphodepletion with cyclophosphamide/fludarabine, the patients were infused with 3 × 10⁶ CAR NKT cells/m².

The cells were well tolerated, with no dose-limiting toxicities. There were grade 3/4 adverse events, but they occurred before CAR NKT-cell infusion and were thought to be related to lymphodepletion.

NKT-cell frequency and absolute numbers increased in the peripheral blood over baseline and remained elevated at the week 4 assessment.

Two patients had stable disease at 4 weeks, but one had a partial response and a change in Curie score from 2 to 1. The patient’s SPECT- and MIBG-merged scans “revealed a dramatic reduction in the size and MIBG uptake of a bone metastasis. The patient consequently received salvage therapy and achieved a complete response that lasted approximately 6 months,” the investigators noted.

The team found higher percentages of CAR NKT cells in primary tumor and metastatic bone marrow biopsies than in peripheral blood. A high percentage of CAR NKT cells from the tumor specimen, but only a small fraction from the bone metastasis, expressed the GD2-CAR.

This research was funded by Kuur Therapeutics, Alex’s Lemonade Stand Foundation for Childhood Cancer, the American Cancer Society, Cookies for Kids’ Cancer Foundation, and the Cancer Prevention and Research Institute of Texas. Dr. Heczey, Dr. Dotti, and two other researchers are coinventors on pending patent applications for NKT cells in cancer immunotherapy that have been licensed to Kuur Therapeutics for commercial development. Dr. Gottschalk has patent applications in the fields of T-cell and/or gene therapy for cancer. He has relationships with TESSA Therapeutics, Immatics, and Tidal.

The final products reached a mean NKT cell purity of 95%. The proportion of cells positive for the GD2-CAR ranged from 20% to 70% across the three patients.

After lymphodepletion with cyclophosphamide/fludarabine, the patients were infused with 3 × 10⁶ CAR NKT cells/m².

The cells were well tolerated, with no dose-limiting toxicities. There were grade 3/4 adverse events, but they occurred before CAR NKT-cell infusion and were thought to be related to lymphodepletion.

NKT-cell frequency and absolute numbers increased in the peripheral blood over baseline and remained elevated at the week 4 assessment.

Two patients had stable disease at 4 weeks, but one had a partial response and a change in Curie score from 2 to 1. The patient’s SPECT- and MIBG-merged scans “revealed a dramatic reduction in the size and MIBG uptake of a bone metastasis. The patient consequently received salvage therapy and achieved a complete response that lasted approximately 6 months,” the investigators noted.

The team found higher percentages of CAR NKT cells in primary tumor and metastatic bone marrow biopsies than in peripheral blood. A high percentage of CAR NKT cells from the tumor specimen, but only a small fraction from the bone metastasis, expressed the GD2-CAR.

People with a history of heart failure – no matter the type – face more complications and death than their peers without HF once hospitalized with COVID-19, a new observational study shows.

A history of HF was associated with a near doubling risk of in-hospital mortality and ICU care and more than a tripling risk of mechanical ventilation despite adjustment for 18 factors including race, obesity, diabetes, previous treatment with renin-angiotensin-aldosterone system (RAAS) inhibitors, and severity of illness.

Adverse outcomes were high regardless of whether patients had HF with a preserved, mid-range, or reduced left ventricular ejection fraction (HFpEF/HFmrEF/HFrEF).

“That for me was the real zinger,” senior author Anuradha Lala, MD, said in an interview . “Because as clinicians, oftentimes, and wrongly so, we think this person has preserved ejection fraction, so they’re not needing my heart failure expertise as much as someone with heart failure with reduced ejection fraction.”

In the peak of the pandemic, that may have meant triaging patients with HFpEF to a regular floor, whereas those with HFrEF were seen by the specialist team.

“What this alerted me to is to take heart failure as a diagnosis very seriously, regardless of ejection fraction, and that is very much in line with all of the emerging data about heart failure with preserved ejection fraction,” said Dr. Lala, from the Icahn School of Medicine at Mount Sinai, New York.

“Now when I see patients in the clinic, I incorporate part of our visit to talking about what they are doing to prevent COVID, which I really wasn’t doing before. It was like ‘Oh yeah, what crazy times we’re dealing with’ and then addressing their heart failure as I normally would,” she said. “But now, interwoven into every visit is: Are you wearing a mask, what’s your social distancing policy, who are you living with at home, has anyone at home or who you’ve interacted with been sick? I’m asking those questions just as a knee-jerk reaction for these patients because I know the repercussions. We have to keep in mind these are observational studies, so I can’t prove causality but these are observations that are, nonetheless, quite robust.”

Although cardiovascular disease, including HF, is recognized as a risk factor for worse outcomes in COVID-19 patients, data are sparse on the clinical course and prognosis of patients with preexisting HF.

“I would have expected that there would have been a gradation of risk from the people with very low ejection fractions up into the normal range, but here it didn’t seem to matter at all. So that’s an important point that bad outcomes were independent of ejection fraction,” commented Lee Goldberg, MD, professor of medicine and chief of advanced heart failure and cardiac transplant at the University of Pennsylvania, Philadelphia.

The study also validated that there is no association between use of RAAS inhibitors and bad outcomes in patients with COVID-19, he said.

Although this has been demonstrated in several studies, concerns were raised early in the pandemic that ACE inhibitors and angiotensin receptor blockers could facilitate infection with SARS-CoV-2 and increase the risk of severe or lethal COVID-19.  

“For most clinicians that question has been put to bed, but we’re still getting patients that will ask during office visits ‘Is it safe for me to stay on?’ They still have that doubt [about] ‘Are we doing the right thing?’ ” Dr. Goldberg said.

“We can reassure them now. A lot of us are able to say there’s nothing to that, we’re very clear about this, stay on the meds. If anything, there’s data that suggest actually it may be better to be on an ACE inhibitor; that the hospitalizations were shorter and the outcomes were a little bit better.”  

For the current study, published online Oct. 28 in the Journal of the American College of Cardiology, the investigators analyzed 6,439 patients admitted for COVID-19 at one of five Mount Sinai Health System hospitals in New York between Feb. 27 and June 26. Their mean age was 65.3 years, 45% were women, and one-third were treated with RAAS inhibitors before admission.

Using ICD-9/10 codes and individual chart review, HF was identified in 422 patients (6.6%), of which 250 patients had HFpEF (≥50%), 44 had HFmrEF (41%-49%), and 128 had HFrEF (≤40%).

Patients with HFpEF were older, more frequently women with a higher body mass index and history of lung disease than patients with HFrEF, whereas those with HFmrEF fell in between.

The HFpEF group was also treated with hydroxychloroquine or macrolides and noninvasive ventilation more frequently than the other two groups, whereas antiplatelet and neurohormonal therapies were more common in the HFrEF group.

Patients with a history of HF had significantly longer hospital stays than those without HF (8 days vs. 6 days), increased need for intubation (22.8% vs. 11.9%) and ICU care (23.2% vs. 16.6%), and worse in-hospital mortality (40% vs. 24.9%).

After multivariable regression adjustment, HF persisted as an independent risk factor for ICU care (odds ratio, 1.71; 95% CI, 1.25-2.34), intubation and mechanical ventilation (OR, 3.64; 95% CI, 2.56-5.16), and in-hospital mortality (OR, 1.88; 95% CI, 1.27-2.78).

“I knew to expect higher rates of adverse outcomes but I didn’t expect it to be nearly a twofold increase,” Dr. Lala said. “I thought that was pretty powerful.”

No significant differences were seen across LVEF categories in length of stay, need for ICU care, intubation and mechanical ventilation, acute kidney injury, shock, thromboembolic events, arrhythmias, or 30-day readmission rates.

However, cardiogenic shock (7.8% vs. 2.3% vs. 2%) and HF-related causes for 30-day readmissions (47.1% vs. 0% vs. 8.6%) were significantly higher in patients with HFrEF than in those with HFmrEF or HFpEF.

Also, mortality was lower in those with HFmrEF (22.7%) than with HFrEF (38.3%) and HFpEF (44%). The group was small but the “results suggested that patients with HFmrEF could have a better prognosis, because they can represent a distinct and more favorable HF phenotype,” the authors wrote.

The statistical testing didn’t show much difference and the patient numbers were very small, noted Dr. Goldberg. “So they might be overreaching a little bit there.”

“To me, the take-home message is that just having the phenotype of heart failure, regardless of EF, is associated with bad outcomes and we need to be vigilant on two fronts,” he said. “We really need to be doing prevention in the folks with heart failure because if they get COVID their outcomes are not going to be as good. Second, as clinicians, if we see a patient presenting with COVID who has a history of heart failure we may want to be much more vigilant with that individual than we might otherwise be. So I think there’s something to be said for kind of risk-stratifying people in that way.”

Dr. Goldberg pointed out that the study had many “amazing strengths,” including a large, racially diverse population, direct chart review to identify HF patients, and capturing a patient’s specific HF phenotype.  

Weaknesses are that it was a single-center study, so the biases of how these patients were treated are not easily controlled for, he said. “We also don’t know when the hospital system was very strained as they were making some decisions: Were the older patients who had advanced heart and lung disease ultimately less aggressively treated because they felt they wouldn’t survive?”

Dr. Lala has received personal fees from Zoll, outside the submitted work. Dr. Goldberg reported research funding with Respicardia and consulting fees from Abbott.

The Pharmaceutical Research and Manufacturers of America led the health sector in spending on lobbying through the first three quarters of 2020, and health care as a whole spent more than any of the other 12 sectors of the U.S. economy, according to the Center for Responsive Politics.

PhRMA spent $20.7 million on lobbying through the end of September, good enough for third on the overall list of U.S. companies and organizations. Three other members of the health sector made the top 10: the American Hospital Association ($18.3 million), BlueCross/BlueShield ($16.3 million), and the American Medical Association ($15.2 million), the center reported.

Total spending by the health sector was $464 million from Jan. 1 to Sept. 30, topping the finance/insurance/real estate sector at $403 million, and miscellaneous business at $371 million. Miscellaneous business is the home of the U.S. Chamber of Commerce, the annual leader in such spending for the last 20 years, based on data from the Senate Office of Public Records.

The largest share of health sector spending came from pharmaceuticals/health products, with a total of almost $233 million, just slightly more than the sector’s four other constituents combined: hospitals/nursing homes ($80 million), health services/HMOs ($75 million), health professionals ($67 million), and miscellaneous health ($9.5 million), the center said on OpenSecrets.org.

Taking one step down from the sector level, that $233 million made pharmaceuticals/health products the highest spending of about 100 industries in 2020, nearly doubling the efforts of electronics manufacturing and equipment ($118 million), which came a distant second. Hospitals/nursing homes was eighth on the industry list, the center noted.

Within minutes of her arrival at Community North Hospital in Indianapolis, Ramya Yeleti’s vital signs plummeted; her pulse was at 45 beats per minute and her ejection fraction was hovering near 10%. “I definitely thought there was a chance I would close my eyes and never open them again, but I only had a few seconds to process that,” she recalled. Then everything went black. Ramya fell unconscious as shock pads were positioned and a swarm of clinicians prepared to insert an Impella heart pump through a catheter into her aorta.

The third-year medical student and aspiring psychiatrist had been doing in-person neurology rotations in July when she began to experience fever and uncontrolled vomiting. Her initial thought was that she must have caught the flu from a patient.

After all, Ramya, along with her father Ram Yeleti, MD, mother Indira, and twin sister Divya, had all weathered COVID-19 in previous months and later tested positive for SARS-CoV-2 antibodies. The only family member who had been spared was her younger brother Rohith.

Indira suffered a severe case, requiring ICU care for 2 days but no ventilator; the others experienced mostly mild symptoms. Ramya — who was studying for her third-year board exams after classes at Marian University College of Osteopathic Medicine in Indianapolis went virtual in March — was left with lingering fatigue; however, her cough and muscle aches abated and her sense of taste and smell returned. When she started rotations, she thought her life was getting back to normal.

Ramya’s flu symptoms did not improve. A university-mandated rapid COVID test came back negative, but 2 more days of vomiting started to worry both her and her father, who is a cardiologist and chief physician executive at Community Health Network in Indianapolis. After Ramya felt some chest pain, she asked her father to listen to her heart. All sounded normal, and Ram prescribed ondansetron for her nausea.

But the antiemetic didn’t work, and by the next morning both father and daughter were convinced that they needed to head to the emergency department.

“I wanted to double-check if I was missing something about her being dehydrated,” Ram told Medscape Medical News. “Several things can cause protracted nausea, like hepatitis, appendicitis, or another infection. I feel terribly guilty I didn’t realize she had a heart condition.”
 

A surprising turn for the worst

Ramya’s subtle symptoms quickly gave way to the dramatic cardiac crisis that unfolded just after her arrival at Community North. “Her EKG looked absolutely horrendous, like a 75-year-old having a heart attack,” Ram said.

As a cardiologist, he knew his daughter’s situation was growing dire when he heard physicians shouting that the Impella wasn’t working and she needed extracorporeal membrane oxygenation (ECMO).

“At that point, I didn’t think she’d survive,” her father recalled. “We had 10 physicians in the room who worked on her for 5 hours to get her stabilized.”

“It was especially traumatic because, obviously, I knew exactly what was happening,” he added. “You can’t sugarcoat anything.”

After being connected to the heart–lung equipment, Ramya was transferred to IU Health Methodist Hospital, also in Indianapolis, where she was tested again for COVID-19. Unlike the rapid test administered just days earlier, the PCR assay came back positive.

“I knew she had acute myocarditis, but coronavirus never crossed my mind,” said Ram.

“As we were dealing with her heart, we were also dealing with this challenge: she was coming back positive for COVID-19 again,” said Roopa Rao, MD, the heart failure transplant cardiologist at IU Health who treated Ramya.

“We weren’t sure whether we were dealing with an active infection or dead virus” from her previous infection, Rao said, “so we started treating her like she had active COVID-19 and gave her remdesivir, convalescent plasma, and steroids, which was the protocol in our hospital.”

A biopsy of Ramya’s heart tissue, along with blood tests, indicated a past parvovirus infection. It’s possible that Ramya’s previous coronavirus infection made her susceptible to heart damage from a newer parvovirus infection, said Rao. Either virus, or both together, could have been responsible for the calamity.

Although it was unheard of during Ramya’s cardiac crisis in early August, evolving evidence now raises the possibility that she is one of a handful of people in the world to be reinfected with SARS-CoV-2. Also emerging are cases of COVID-related myocarditis and other extreme heart complications, particularly in young people.

“At the time, it wasn’t really clear if people could have another infection so quickly,” Rao told Medscape Medical News. “It is possible she is one of these rare individuals to have COVID-19 twice. I’m hoping at some point we will have some clarity.”

“I would favor a coinfection as probably the triggering factor for her sickness,” she said. “It may take some time, but like any other disease — and it doesn’t look like COVID will go away magically — I hope we’ll have some answers down the road.”
 

Another wrinkle

The next 48 hours brought astonishing news: Ramya’s heart function had rebounded to nearly normal, and her ejection fraction increased to about 45%. Heart transplantation wouldn’t be necessary, although Rao stood poised to follow through if ECMO only sustained, rather than improved, Ramya’s prognosis.

“Ramya was so sick that if she didn’t recover, the only option would be a heart transplant,” said Rao. “But we wanted to do everything to keep that heart.”

After steroid and COVID treatment, Ramya’s heart started to come back. “It didn’t make sense to me,” said Rao. “I don’t know what helped. If we hadn’t done ECMO, her heart probably wouldn’t have recovered, so I would say we have to support these patients and give them time for the heart to recover, even to the point of ECMO.”

Despite the good news, Ramya’s survival still hung in the balance. When she was disconnected from ECMO, clinicians discovered that the Impella device had caused a rare complication, damaging her mitral valve. The valve could be repaired surgically, but both Rao and Ram felt great trepidation at the prospect of cardiopulmonary bypass during the open-heart procedure.

“They would need to stop her heart and restart it, and I was concerned it would not restart,” Ram explained. “I didn’t like the idea of open-heart surgery, but my biggest fear was she was not going to survive it because of a really fresh, sick heart.”

The cardiologists’ fears did, in fact, come to pass: it took an hour to coax Ramya’s heart back at the end of surgery. But, just as the surgeon was preparing to reconnect Ramya to ECMO in desperation, “her heart recovered again,” Rao reported.

“Some things you never forget in life,” she said. “I can’t describe how everyone in the OR felt, all taking care of her. I told Ramya, ‘you are a fighter’.”
 

New strength

Six days would pass before Ramya woke up and learned of the astounding series of events that saved her. She knew “something was really wrong” because of the incision at the center of her chest, but learning she’d been on ECMO and the heart transplant list drove home how close to death she’d actually come.

“Most people don’t get off ECMO; they die on it,” she said. “And the chances of dying on the heart transplant list are very high. It was very strange to me that this was my story all of a sudden, when a week and a half earlier I was on rotation.”

Ongoing physical therapy over the past 3 months has transformed Ramya from a state of profound physical weakness to a place of relative strength. The now-fourth-year med student is turning 26 in November and is hungry to restart in-person rotations. Her downtime has been filled in part with researching myocarditis and collaborating with Rao on her own case study for journal publication.

But the mental trauma from her experience has girded her in ways she knows will make her stronger personally and professionally in the years ahead.

“It’s still very hard. I’m still recovering,” she acknowledged. “I described it to my therapist as an invisible wound on my brain.”

“When I came out of the hospital, I still had ECMO wounds, deep gashes on my legs that affected how fast and how long I could walk,” she said. “I felt like the same thing was going on my brain — a huge cut no one could see.”

Her intention to specialize in psychiatry has become more pressing now that Ramya has realized the impact of trauma on mental health.

“My body failing me was awful, but I could handle it,” she said. “Losing any part of my mind would have been way worse. I want to take care of that in my patients.”

Within minutes of her arrival at Community North Hospital in Indianapolis, Ramya Yeleti’s vital signs plummeted; her pulse was at 45 beats per minute and her ejection fraction was hovering near 10%. “I definitely thought there was a chance I would close my eyes and never open them again, but I only had a few seconds to process that,” she recalled. Then everything went black. Ramya fell unconscious as shock pads were positioned and a swarm of clinicians prepared to insert an Impella heart pump through a catheter into her aorta.

The third-year medical student and aspiring psychiatrist had been doing in-person neurology rotations in July when she began to experience fever and uncontrolled vomiting. Her initial thought was that she must have caught the flu from a patient.

After all, Ramya, along with her father Ram Yeleti, MD, mother Indira, and twin sister Divya, had all weathered COVID-19 in previous months and later tested positive for SARS-CoV-2 antibodies. The only family member who had been spared was her younger brother Rohith.

Indira suffered a severe case, requiring ICU care for 2 days but no ventilator; the others experienced mostly mild symptoms. Ramya — who was studying for her third-year board exams after classes at Marian University College of Osteopathic Medicine in Indianapolis went virtual in March — was left with lingering fatigue; however, her cough and muscle aches abated and her sense of taste and smell returned. When she started rotations, she thought her life was getting back to normal.

Ramya’s flu symptoms did not improve. A university-mandated rapid COVID test came back negative, but 2 more days of vomiting started to worry both her and her father, who is a cardiologist and chief physician executive at Community Health Network in Indianapolis. After Ramya felt some chest pain, she asked her father to listen to her heart. All sounded normal, and Ram prescribed ondansetron for her nausea.

But the antiemetic didn’t work, and by the next morning both father and daughter were convinced that they needed to head to the emergency department.

“I wanted to double-check if I was missing something about her being dehydrated,” Ram told Medscape Medical News. “Several things can cause protracted nausea, like hepatitis, appendicitis, or another infection. I feel terribly guilty I didn’t realize she had a heart condition.”
 

A surprising turn for the worst

Ramya’s subtle symptoms quickly gave way to the dramatic cardiac crisis that unfolded just after her arrival at Community North. “Her EKG looked absolutely horrendous, like a 75-year-old having a heart attack,” Ram said.

As a cardiologist, he knew his daughter’s situation was growing dire when he heard physicians shouting that the Impella wasn’t working and she needed extracorporeal membrane oxygenation (ECMO).

“At that point, I didn’t think she’d survive,” her father recalled. “We had 10 physicians in the room who worked on her for 5 hours to get her stabilized.”

“It was especially traumatic because, obviously, I knew exactly what was happening,” he added. “You can’t sugarcoat anything.”

For reasons unknown, about one in six people who recovered from COVID-19 subsequently retested positive at least 2 weeks later, researchers reported in a study in Italy.

Sore throat and rhinitis were the only symptoms associated with a positive result. “Patients who continued to have respiratory symptoms, especially, were more likely to have a new positive test result,” lead author Francesco Landi, MD, PhD, said in an interview.

“This suggests the persistence of respiratory symptoms should not be underestimated and should be adequately assessed in all patients considered recovered from COVID-19,” he said.

“The study results are interesting,” Akiko Iwasaki, PhD, an immunobiologist at Yale University and the Howard Hughes Medical Institute, both in New Haven, Conn.,, said in an interview. “There are other reports of RNA detection postdischarge, but this study ... found that only two symptoms out of many – sore throat and rhinitis – were higher in those with PCR [polymerase chain reaction]-positive status.”

The study was published online Sept. 18 in the American Journal of Preventive Medicine.

The findings could carry important implications for people who continue to be symptomatic. “It is reasonable to be cautious and avoid close contact with others, wear a face mask, and possibly undergo an additional nasopharyngeal swab,” said Dr. Landi, associate professor of internal medicine at Catholic University of the Sacred Heart in Rome.

“One of most interesting findings is that persistent symptoms do not correlate with PCR positivity, suggesting that symptoms are in many cases not due to ongoing viral replication,” Jonathan Karn, PhD, professor and chair of the department of molecular biology and microbiology at Case Western Reserve University, Cleveland, said in an interview.

“The key technical problem, which they have discussed, is that a viral RNA signal in the PCR assay does not necessarily mean that infectious virus is present,” Dr. Karn said. He added that new comprehensive viral RNA analyses would be needed to answer this question.
 

Official COVID-19 recovery

To identify risk factors and COVID-19 survivors more likely to retest positive, Dr. Landi and members of the Gemelli Against COVID-19 Post-Acute Care Study Group evaluated 131 people after hospital discharge.

All participants met World Health Organization criteria for release from isolation, including two negative test results at least 24 hours apart, and were studied between April 21 and May 21. Mean age was 56 and 39% were women. Only a slightly higher mean body mass index of 27.6 kg/m² in the positive group versus 25.9 in the negative group, was significant.

Although 51% of survivors reported fatigue, 44% had dyspnea, and 17% were coughing, the rates did not differ significantly between groups. In contrast, 18% of positive survivors and 4% of negative survivors had a sore throat (P = .04), and 27% versus 12%, respectively, reported rhinitis (P = .05).

People returned for follow-up visits a mean 17 days after the second negative swab test.
 

Asymptomatic COVID-19 carriers

“These findings indicate that a noteworthy rate of recovered patients with COVID-19 could still be asymptomatic carriers of the virus,” the researchers noted in the paper. “Even in the absence of specific guidelines, the 22 patients who tested positive for COVID-19 again were suggested to quarantine for a second time.”

No family member or close contact of the positive survivors reported SARS-CoV-2 infection. All patients continued to wear masks and observe social distancing recommendations, which makes it “very difficult to affirm whether these patients were really contagious,” the researchers noted.
 

Next steps

Evaluating all COVID-19 survivors to identify any who retest positive “will be a crucial contribution to a better understanding of both the natural history of COVID-19 as well as the public health implications of viral shedding,” the authors wrote.

One study limitation is that the reverse transcriptase–PCR test reveals genetic sequences specific to COVID-19. “It is important to underline that this is not a viral culture and cannot determine whether the virus is viable and transmissible,” the researchers noted.

“In this respect, we are trying to better understand if the persistence of long-time positive [reverse transcriptase]–PCR test for COVID-19 is really correlated to a potential contagiousness,” they added.

Dr. Landi and colleagues said their findings should be considered preliminary, and larger data samples are warranted to validate the results.

Dr. Landi and Dr. Karn disclosed no relevant financial relationships. Dr. Iwasaki disclosed a research grant from Condair, a 5% or greater equity interest in RIGImmune, and income of $250 or more from PureTec.

Although 51% of survivors reported fatigue, 44% had dyspnea, and 17% were coughing, the rates did not differ significantly between groups. In contrast, 18% of positive survivors and 4% of negative survivors had a sore throat (P = .04), and 27% versus 12%, respectively, reported rhinitis (P = .05).

People returned for follow-up visits a mean 17 days after the second negative swab test.
 

Asymptomatic COVID-19 carriers

“These findings indicate that a noteworthy rate of recovered patients with COVID-19 could still be asymptomatic carriers of the virus,” the researchers noted in the paper. “Even in the absence of specific guidelines, the 22 patients who tested positive for COVID-19 again were suggested to quarantine for a second time.”

No family member or close contact of the positive survivors reported SARS-CoV-2 infection. All patients continued to wear masks and observe social distancing recommendations, which makes it “very difficult to affirm whether these patients were really contagious,” the researchers noted.
 

Next steps

Evaluating all COVID-19 survivors to identify any who retest positive “will be a crucial contribution to a better understanding of both the natural history of COVID-19 as well as the public health implications of viral shedding,” the authors wrote.

One study limitation is that the reverse transcriptase–PCR test reveals genetic sequences specific to COVID-19. “It is important to underline that this is not a viral culture and cannot determine whether the virus is viable and transmissible,” the researchers noted.

“In this respect, we are trying to better understand if the persistence of long-time positive [reverse transcriptase]–PCR test for COVID-19 is really correlated to a potential contagiousness,” they added.

Dr. Landi and colleagues said their findings should be considered preliminary, and larger data samples are warranted to validate the results.

Dr. Landi and Dr. Karn disclosed no relevant financial relationships. Dr. Iwasaki disclosed a research grant from Condair, a 5% or greater equity interest in RIGImmune, and income of $250 or more from PureTec.

Federal advisers who will help determine which Americans get the first COVID vaccines took an in-depth look Oct. 30 at the challenges they face in selecting priority groups.

The Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) will face two key decisions once a COVID vaccine wins clearance from the US Food and Drug Administration (FDA).

ACIP will need to decide whether to recommend its use in adults (the age group in which vaccines are currently being tested). The group will also need to offer direction on which groups should get priority in vaccine allocation, inasmuch as early supplies will not be sufficient to vaccinate everyone.

At the Oct. 30 meeting, CDC’s Kathleen Dooling, MD, MPH, suggested that ACIP plan on tackling these issues as two separate questions when it comes time to weigh in on an approved vaccine. Although there was no formal vote among ACIP members at the meeting, Dooling’s proposal for tackling a future recommendation in a two-part fashion drew positive feedback.

ACIP member Katherine A. Poehling, MD, MPH, suggested that the panel and CDC be ready to reexamine the situation frequently regarding COVID vaccination. “Perhaps we could think about reviewing data on a monthly basis and updating the recommendation, so that we can account for the concerns and balance both the benefits and the [potential] harm,” Poehling said.

Dooling agreed. “Both the vaccine recommendation and allocation will be revisited in what is a very dynamic situation,” Dooling replied to Poehling. “So all new evidence will be brought to ACIP, and certainly the allocation as vaccine distribution proceeds will need to be adjusted accordingly.”
 

Ethics and limited evidence

During the meeting, ACIP members repeatedly expressed discomfort with the prospect of having to weigh in on widespread use of COVID vaccines on the basis of limited evidence.

Within months, FDA may opt for a special clearance, known as an emergency use authorization (EUA), for one or more of the experimental COVID vaccines now in advanced testing. Many of FDA’s past EUA clearances were granted for test kits. For those EUA approvals, the agency considered risks of false results but not longer-term, direct harm to patients from these products.

With a COVID vaccine, there will be strong pressure to distribute doses as quickly as possible with the hope of curbing the pandemic, which has already led to more than 229,000 deaths in the United States alone and has disrupted lives and economies around the world. But questions will persist about the possibility of serious complications from these vaccines, ACIP members noted.

“My personal struggle is the ethical side and how to balance these two,” said ACIP member Robert L. Atmar, MD, of Baylor College of Medicine, Houston, Texas, who noted that he expects his fellow panelists to share this concern.

Currently, four experimental COVID vaccines likely to be used in the United States have advanced to phase 3 testing. Pfizer Inc and BioNtech have enrolled more than 42,000 participants in a test of their candidate, BNT162b2 vaccine, and rival Moderna has enrolled about 30,000 participants in a test of its mRNA-1273 vaccine, CDC staff said.

The other two advanced COVID vaccine candidates have overcome recent hurdles. AstraZeneca Plc on Oct. 23 announced that FDA had removed a hold on the testing of its AZD1222 vaccine candidate; the trial will enroll approximately 30,000 people. Johnson & Johnson’s Janssen unit also announced that day the lifting of a safety pause for its Ad26.COV2.S vaccine; the phase 3 trial for that vaccine will enroll approximately 60,000 volunteers. Federal agencies, states, and territories have developed plans for future distribution of COVID vaccines, CDC staff said in briefing materials for today’s ACIP meeting.

Several ACIP members raised many of the same concerns that members of an FDA advisory committee raised at a meeting earlier in October. ACIP and FDA advisers honed in on the FDA’s decision to set a median follow-up duration of 2 months in phase 3 trials in connection with expected EUA applications for COVID-19 vaccines.

“I struggle with following people for 2 months after their second vaccination as a time point to start making final decisions about safety,” said ACIP member Sharon E. Frey, MD, a professor at St. Louis University School of Medicine, St. Louis, Missouri. “I just want to put that out there.”
 

Medical front line, then who?

There is consensus that healthcare workers be in the first stage ― Phase 1 ― of distribution. That recommendation was made in a report from the National Academies of Sciences, Engineering, and Medicine (NASEM). Phase 1A would include first responders; Phase 1B might include people of all ages who have two or more comorbidities that put them at significantly higher risk for COVID-19 or death, as well as older adults living in congregate or overcrowded settings, the NASEM report said.

A presentation from the CDC’s Matthew Biggerstaff, ScD, MPH, underscored challenges in distributing what are expected to be limited initial supplies of COVID vaccines.

Biggerstaff showed several scenarios the CDC’s Data, Analytics, and Modeling Task Force had studied. The initial allocation of vaccines would be for healthcare workers, followed by what the CDC called Phase 1B.

Choices for a rollout may include next giving COVID vaccines to people at high risk, such as persons who have one or more chronic medical conditions, including heart disease, diabetes, kidney disease, or obesity. Other options for the rollout could be to vaccinate people aged 65 years and older or essential workers whose employment puts them in contact with the public, thus raising the risk of contracting the virus.

The CDC’s research found that the greatest impact in preventing death was to initially vaccinate adults aged 65 and older in Phase 1B. The agency staff described this approach as likely to result in an about “1 to 11% increase in averted deaths across the scenarios.”

Initially vaccinating essential workers or high-risk adults in Phase 1B would avert the most infections. The agency staff described this approach as yielding about “1 to 5% increase in averted infections across the scenarios,” Biggerstaff said during his presentation.

The following are other findings of the CDC staff:

The earlier the vaccine rollout relative to increasing transmission, the greater the averted percentage and differences between the strategies.

Differences were not substantial in some scenarios.

The need to continue efforts to slow the spread of COVID-19 should be emphasized.

Adverse effects

ACIP members also heard about strategies for tracking potential side effects of future vaccines. A presentation by Tom Shimabukuro, MD, MPH, MBA, from the CDC’s COVID-19 Vaccine Task Force/Vaccine Safety Team, included details about a new smartphone-based active surveillance program for COVID-19 vaccine safety.

Known as v-safe, this system would use Web-based survey monitoring and incorporate text messaging. It would conduct electronic health checks on vaccine recipients, which would occur daily during the first week post vaccination and weekly thereafter for 6 weeks from the time of vaccination.

Clinicians “can play an important role in helping CDC enroll patients in v-safe at the time of vaccination,” Shimabukuro noted in his presentation. This would add another task, though, for clinicians, the CDC staff noted.
 

Pregnancy and breastfeeding are special concerns

Of special concern with the rollout of a COVID vaccine are recommendations regarding pregnancy and breastfeeding. Women constitute about 75% of the healthcare workforce, CDC staff noted.

At the time the initial ACIP COVID vaccination recommendations are made, there could be approximately 330,000 healthcare personnel who are pregnant or who have recently given birth. Available data indicate potentially increased risks for severe maternal illness and preterm birth associated with SARS-CoV-2 infection, said CDC’s Megan Wallace, DrPH, MPH, in a presentation for the Friday meeting.

In an Oct. 27 letter to ACIP, Chair Jose Romero, the American College of Obstetricians and Gynecologists (ACOG), urged the panel to ensure that pregnant women and new mothers in the healthcare workforce have priority access to a COVID vaccine. Pregnant and lactating women were “noticeably and alarmingly absent from the NASEM vaccine allocation plan for COVID-19,” wrote Christopher M. Zahn, MD, vice president for practice activities at ACOG, in the letter to Romero.

“ACOG urges ACIP to incorporate pregnant and lactating women clearly and explicitly into its COVID-19 vaccine allocation and prioritization framework,” Zahn wrote. “Should an Emergency Use Authorization be executed for one or more COVID-19 vaccines and provide a permissive recommendation for pregnant and lactating women, pregnant health care workers, pregnant first responders, and pregnant individuals with underlying conditions should be prioritized for vaccination alongside their non-pregnant peers.”
