Latest from ISCHEMIA: Worse outcomes in patients with intermediate left main disease on CCTA

Mon, 06/01/2020 - 11:09

Patients in the landmark ISCHEMIA trial with intermediate left main disease had a greater extent of coronary artery disease on invasive angiography, indicating greater atherosclerotic burden. They also had worse prognosis with a higher risk of cardiovascular events.

Dr. Sripal Bangalore

“Many times, we are looking at results as to whether patients have left main disease or not,” Sripal Bangalore, MD, said during the Society for Cardiovascular Angiography & Interventions virtual annual scientific sessions. “Here, we are showing that it’s not black and white; there are shades of gray. If a patient has intermediate left main disease, the prognosis is worse. That’s very important information we need to convey to our referrals also, because many times they may just look at the bottom line and say, ‘there is no left main disease.’ But here, we’re seeing that even having intermediate left main disease has significantly worse prognosis. We need to take that seriously.”

Prior studies show that patients with significant left main disease (LMD; defined as 50% or greater stenosis on coronary CT angiography [CCTA]) have a high risk of cardiovascular events and guidelines recommend revascularization to improve survival, said Dr. Bangalore, an interventional cardiologist at New York University Langone Health. However, the impact of intermediate LMD (defined as 25%-49% stenosis on CCTA) on outcomes is unclear.

Members of the ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) research group randomized 5,179 participants to an initial invasive or conservative strategy. The main results showed that immediate revascularization in patients with stable ischemic heart disease provided no reduction in cardiovascular endpoints through 4 years of follow-up, compared with initial optimal medical therapy alone.
 

‘Discordance’ revealed in imaging modalities

For the current analysis, named the ISCHEMIA Intermediate LM Substudy, those who underwent coronary CCTA comprise the LMD substudy cohort. The objective was to evaluate clinical and quality of life outcomes in patients with and without intermediate left main disease on coronary CT and to evaluate the impact of treatment strategy on those outcomes across subgroups.

At baseline, these patients were categorized into those with and without intermediate LMD as determined by a core lab. Patients with LMD of 50% or greater, those with prior coronary artery bypass graft surgery, and those with nonevaluable or missing data on LM stenosis were excluded.

Among the 3,913 ISCHEMIA participants who underwent CCTA, 3,699 satisfied the inclusion criteria. Of these patients, 962 (26%) had intermediate LMD and 2,737 (74%) did not.

The researchers observed no significant differences in baseline characteristics between patients with and without LMD. However, patients with intermediate LMD tended to be older, and a greater proportion had hypertension and diabetes. Stress test characteristics were also similar between patients with and without LMD. However, patients with intermediate LMD tended toward a greater severity of severe ischemia.

This was also true for anatomic disease on CCTA. A higher proportion of patients with intermediate LMD had triple-vessel disease (61%-62%, compared with 36%-40% along those without intermediate LMD). In addition, a higher proportion of patients with intermediate LMD had stenosis in the proximal left anterior artery descending (LAD) artery (65% vs. 39% among those without intermediate LMD).

On analysis limited to 1,846 patients who underwent invasive angiography treatment in the main ISCHEMIA trial, 7% of those who were categorized into the intermediate LMD group were found to have LMD disease of 50% or greater, compared with 1.4% of patients who were categorized as not having intermediate LMD. “This goes to show this discordance between the two modalities [CCTA and coronary angiography], and I think we have to be careful,” said Dr. Bangalore, who also directs NYU Langone’s Cardiac Catheterization Laboratory. “There may be patients with left main disease, even if the CCTA says it’s not at 25%-29% [stenosis].”

The researchers found that, among patients who underwent invasive angiography, a greater proportion of those who were categorized into the LMD group had proximal LAD disease (43% vs. 33% among those who were categorized into the nonintermediate LMD group), triple-vessel disease (47% vs. 35%), a greater extent of coronary artery disease as denoted by a higher SYNTAX score (21 vs. 15), and a higher proportion underwent coronary artery bypass graft surgery (32% vs. 18%).
 

 

 

Intermediate LMD linked to worse outcomes

After the researchers adjusted for baseline differences between the two groups in overall substudy cohort, they found that intermediate LMD severity was an independent predictor of the primary composite endpoint of cardiovascular death, MI, hospitalization for unstable angina, heart failure, and resuscitated cardiac arrest (hazard ratio, 1.31; P = .0123); cardiovascular death/MI/stroke (HR, 1.30; P = .0143); procedural primary MI (HR, 1.64; P = .0487); heart failure (HR, 2.06; P = .0239); and stroke (HR, 1.82, P = .0362).

“We then looked to see if there is a treatment difference, a treatment effect based on whether patients had intermediate LMD,” Dr. Bangalore said. “Most of the P values were not significant. The results are very consistent with what we saw in the main analysis: not a significant difference between invasive and conservative strategy. We do see some differences, though. An invasive strategy was associated with a significantly higher risk of procedural MI [2.9% vs. 1.5%], but a significantly lower risk of nonprocedural MI [–6.4% vs. –2%].”

Dr. Bangalore added that there was significant benefit of the invasive strategy in reducing angina and improving quality of life based on the Seattle Angina Questionnaire-7. “This result was durable up to 48 months of follow-up, whether the patient had intermediate left main disease or not. These results were dependent on baseline angina status. The benefit of invasive strategy was mainly in patients who had daily, weekly, and monthly angina, and no benefit in patients with no angina; there was no interaction based on intermediate left main status.”

Dr. Bangalore emphasized that the original ISCHEMIA trial excluded patients with severe left main disease by design. “But patients with intermediate left main disease in ISCHEMIA tended to have a greater extent of coronary artery disease, indicating greater atherosclerotic burden. I don’t think that’s any surprise. They had a worse prognosis with higher risk of cardiovascular events but similar quality of life, including angina-specific quality of life.”

The key clinical message, he said, is that patients with intermediate LMD face an increased risk of cardiovascular events. “I think we have to be aggressive in trying to reduce their risk with medical therapy, etc.,” he said. “If they are symptomatic, ISCHEMIA tells us that patients have two options. They can choose an invasive strategy, because clearly there is a benefit. You have a significant benefit at making you feel better and potentially reducing the risk of spontaneous MI over a period of time. Or, you can try medical therapy first. If you do see some left main disease, it’s showing the general burden of atherosclerosis disease in those patients. I think that’s the critical message, that we have to be very aggressive with these patients.”
 

A call for more imaging studies

An invited panelist, Timothy D. Henry, MD, said that the results of the ISCHEMIA substudy should stimulate further research. “With an intermediate lesion, clearly the interventional group did better, and it wasn’t symptom related,” said Dr. Henry, medical director of the Carl and Edyth Lindner Center for Research and Education at the Christ Hospital in Cincinnati. “So even if you do medical therapy, you’re not going to really find it out. In my mind, this should stimulate us to do more imaging of the left main that are moderate lesions, and follow this up as an independent study. I think this is a really important finding.”

ISCHEMIA was supported by grants from the National Heart, Lung, and Blood Institute. Dr. Bangalore disclosed that he is a member of the advisory board and/or a board member for Meril, SMT, Pfizer, Amgen, Biotronik, and Abbott. He also is a consultant for Reata Pharmaceuticals.

Despite guidelines, controversy remains over corticosteroids in COVID-19

Article Type

Thu, 08/26/2021 - 16:06

Three main reasons have been put forth for using corticosteroids in critically ill patients with COVID-19, but only one – the hope of preventing lung fibrosis in patients with unresolved acute respiratory distress syndrome – is reasonable to employ now outside of formal randomized trials, Peter Pickkers, MD, PhD, asserted at a webinar on COVID-19 sponsored by the European Society of Intensive Care Medicine.

The most commonly invoked rationale for giving steroids in patients with severe COVID-19 is to modulate the destructive inflammatory immune response that occurs with advancing disease. Another justification cited for giving steroids is to treat suspected adrenal insufficiency in those with refractory shock. Of note, both practices are endorsed in the recent Surviving Sepsis Campaign guidelines on management of critically ill patients with COVID-19 (Intensive Care Med. 2020 May;46[5]:854-87).

But those recommendations – numbers 22 and 42 out of a total of 50 recommendations included in the guidelines – should never have been made, according to Dr. Pickkers, professor of experimental intensive care medicine at Radboud University Medical Center in Nijmegen, the Netherlands.
 

Dueling guidelines

The Surviving Sepsis Campaign guidelines, which were developed by a panel comprising 36 experts in 12 countries, are quite frank in conceding that the guidance in favor of corticosteroids are weak recommendations based on low-quality evidence.

The guidelines recommend against using corticosteroids to try to modulate the immune system in mechanically ventilated COVID-19 patients without acute respiratory distress syndrome (ARDS), but do recommend steroids in those with COVID-19 and ARDS. However, the guidelines also note that, because of the very low quality of the evidence, some experts on the panel preferred not to issue a pro-steroids recommendation at all until higher-quality evidence becomes available. Dr. Pickkers said he believes that the minority view should have prevailed. Moreover, current COVID-19 guidance from the World Health Organization is at odds with the Surviving Sepsis Campaign recommendations; the WHO advises against corticosteroids unless the treatment is indicated for a reason other than immunomodulation, he noted.

The evidence in favor of steroids in an effort to blunt the immune response in COVID patients with ARDS is based largely upon a single small, retrospective, non–peer-reviewed report that 5-7 days of treatment with 1-2 mg/kg per day of methylprednisolone was associated with shortened fever duration and need for supplemental oxygen.

The evidence against steroids for immunomodulation comes mainly from earlier studies of the SARS and MERS novel coronaviruses. For example, in a multicenter study of 309 patients with the MERS (Middle East respiratory syndrome) virus, those who received corticosteroids received no benefit and experienced delayed viral clearance (Am J Respir Crit Care Med. 2018 Mar 15;197[6]:757-67).

“The thing is, virtually all COVID-19 patients in the ICU fulfill the criteria for ARDS, so following the Surviving Sepsis Campaign guidelines would have far-reaching consequences,” Dr. Pickkers said.

Those consequences include a theoretic potential for serious harm arising from dampening the immune response at a point in the course of COVID-19 when the virus is still present, which could result in slowed viral clearance and prolonged viral shedding. Moreover so far no one has been able to identify a sweet spot in the disease course where the viral load has waned and the immune response is sufficiently early that intervention with corticosteroids might have an optimal benefit/risk ratio, he continued.

“My opinion is that at this moment there is no benefit at all for corticosteroids for immunomodulation in patients with COVID-19,” Dr. Pickkers said. “My personal recommendation, in contrast to the Surviving Sepsis Campaign recommendation, is not to use this therapy outside of a study.”

He added that randomized, controlled trials of corticosteroid therapy in critically ill patients with COVID-19 are ongoing in Europe and the United States, including the large RECOVERY study of dexamethasone in the United Kingdom.

As for the Surviving Sepsis Campaign recommendation to use corticosteroids to treat refractory shock in COVID-19, Dr. Pickkers dismissed this guidance as largely irrelevant. That’s because few patients with COVID-19 who need mechanical ventilation have refractory shock as evidenced by the need for a high infusion rate of norepinephrine. Anyway, he noted, that Surviving Sepsis recommendation is based upon extrapolation from evidence of benefit in bacterial septic shock patients, which he deemed to be of questionable relevance to the COVID-19 pandemic.
 

Attacking the fibroproliferative phase of ARDS

First off, Dr. Pickkers conceded, there is no evidence that treatment with corticosteroids to prevent lung fibrosis in COVID-19 patients with nonresolving ARDS is an effective strategy; the pandemic is simply too new at this point for the appropriate studies to have been done. But this much is known: Postmortem pathologic studies show fibroplastic proliferation is present in the lungs of COVID-19 patients, as in those who die of ARDS of other causes. Also, COVID-19 patients typically aren’t admitted to the ICU until day 11 or 12 after developing their first symptoms, so by the time they display indications that their ARDS is not resolving, the virus has typically left the scene; thus, there is little risk at that point that corticosteroids will promote viral proliferation. Additionally, studies in critically ill patients with nonresolving ARDS of other causes show clinically meaningful benefits for corticosteroid therapy.

Dr. Pickkers cited as “must reading” an analysis of five randomized trials of corticosteroid therapy in a total of 518 patients with acute lung injury ARDS of non–COVID-19 origin. The analysis by investigators at the University of Tennessee, Memphis, concluded that treatment resulted in clinically meaningful reductions in duration of mechanical ventilation and ICU length of stay. Moreover, in the 400 patients whose steroid therapy commenced before day 14 of ARDS, there was a statistically significant 22% reduction in risk of death, compared with patients in whom corticosteroids were started later (Intensive Care Med. 2008 Jan;34[1]:61-9).

Session cochair Jan De Waele, MD, PhD, struck a cautious note, remarking, “It’s my perception that we’re using the evidence that we’ve gathered in other conditions and are now trying to apply it in COVID-19. But quality data on patients with COVID-19 itself is pretty scare, and it’s really hard to say whether this disease behaves similarly to bacterial septic shock or to other viral infections.”

“We need more information about the use of corticosteroids in COVID-19, although I think a lot of people are using it at this moment,” added Dr. De Waele, a surgical intensivist at Ghent (Belgium) University.

That being said, he asked Dr. Pickkers when he considers using corticosteroids to prevent pulmonary fibrosis.

Dr. Pickkers said that when he notices that a COVID-19 patient’s lung compliance is worsening, that stiff lung is a clue that fibrosis is occurring and is having clinical consequences. “We also measure blood procollagen, a not very sensitive but moderately specific marker of fibroproliferation. If we see an increase in this biomarker and the lung mechanics are changing, then we do treat these patients with corticosteroids,” Dr. Pickkers replied.

He and his colleagues try to start steroids before day 14 of ARDS, and they continue treatment for longer than 7 days in order to prevent a rebound inflammatory response upon treatment discontinuation. They also avoid using neuromuscular agents and engage in meticulous infection surveillance in order to minimize potential complications of corticosteroid therapy in the ICU.

Dr. Pickkers reported having no financial conflicts regarding his presentation.

The most commonly invoked rationale for giving steroids in patients with severe COVID-19 is to modulate the destructive inflammatory immune response that occurs with advancing disease. Another justification cited for giving steroids is to treat suspected adrenal insufficiency in those with refractory shock. Of note, both practices are endorsed in the recent Surviving Sepsis Campaign guidelines on management of critically ill patients with COVID-19 (Intensive Care Med. 2020 May;46[5]:854-87).

But those recommendations – numbers 22 and 42 out of a total of 50 recommendations included in the guidelines – should never have been made, according to Dr. Pickkers, professor of experimental intensive care medicine at Radboud University Medical Center in Nijmegen, the Netherlands.
 

Dueling guidelines

The Surviving Sepsis Campaign guidelines, which were developed by a panel comprising 36 experts in 12 countries, are quite frank in conceding that the guidance in favor of corticosteroids are weak recommendations based on low-quality evidence.

The guidelines recommend against using corticosteroids to try to modulate the immune system in mechanically ventilated COVID-19 patients without acute respiratory distress syndrome (ARDS), but do recommend steroids in those with COVID-19 and ARDS. However, the guidelines also note that, because of the very low quality of the evidence, some experts on the panel preferred not to issue a pro-steroids recommendation at all until higher-quality evidence becomes available. Dr. Pickkers said he believes that the minority view should have prevailed. Moreover, current COVID-19 guidance from the World Health Organization is at odds with the Surviving Sepsis Campaign recommendations; the WHO advises against corticosteroids unless the treatment is indicated for a reason other than immunomodulation, he noted.

The evidence in favor of steroids in an effort to blunt the immune response in COVID patients with ARDS is based largely upon a single small, retrospective, non–peer-reviewed report that 5-7 days of treatment with 1-2 mg/kg per day of methylprednisolone was associated with shortened fever duration and need for supplemental oxygen.

The evidence against steroids for immunomodulation comes mainly from earlier studies of the SARS and MERS novel coronaviruses. For example, in a multicenter study of 309 patients with the MERS (Middle East respiratory syndrome) virus, those who received corticosteroids received no benefit and experienced delayed viral clearance (Am J Respir Crit Care Med. 2018 Mar 15;197[6]:757-67).

“The thing is, virtually all COVID-19 patients in the ICU fulfill the criteria for ARDS, so following the Surviving Sepsis Campaign guidelines would have far-reaching consequences,” Dr. Pickkers said.

Those consequences include a theoretic potential for serious harm arising from dampening the immune response at a point in the course of COVID-19 when the virus is still present, which could result in slowed viral clearance and prolonged viral shedding. Moreover so far no one has been able to identify a sweet spot in the disease course where the viral load has waned and the immune response is sufficiently early that intervention with corticosteroids might have an optimal benefit/risk ratio, he continued.

“My opinion is that at this moment there is no benefit at all for corticosteroids for immunomodulation in patients with COVID-19,” Dr. Pickkers said. “My personal recommendation, in contrast to the Surviving Sepsis Campaign recommendation, is not to use this therapy outside of a study.”

He added that randomized, controlled trials of corticosteroid therapy in critically ill patients with COVID-19 are ongoing in Europe and the United States, including the large RECOVERY study of dexamethasone in the United Kingdom.

As for the Surviving Sepsis Campaign recommendation to use corticosteroids to treat refractory shock in COVID-19, Dr. Pickkers dismissed this guidance as largely irrelevant. That’s because few patients with COVID-19 who need mechanical ventilation have refractory shock as evidenced by the need for a high infusion rate of norepinephrine. Anyway, he noted, that Surviving Sepsis recommendation is based upon extrapolation from evidence of benefit in bacterial septic shock patients, which he deemed to be of questionable relevance to the COVID-19 pandemic.
 

Attacking the fibroproliferative phase of ARDS

First off, Dr. Pickkers conceded, there is no evidence that treatment with corticosteroids to prevent lung fibrosis in COVID-19 patients with nonresolving ARDS is an effective strategy; the pandemic is simply too new at this point for the appropriate studies to have been done. But this much is known: Postmortem pathologic studies show fibroplastic proliferation is present in the lungs of COVID-19 patients, as in those who die of ARDS of other causes. Also, COVID-19 patients typically aren’t admitted to the ICU until day 11 or 12 after developing their first symptoms, so by the time they display indications that their ARDS is not resolving, the virus has typically left the scene; thus, there is little risk at that point that corticosteroids will promote viral proliferation. Additionally, studies in critically ill patients with nonresolving ARDS of other causes show clinically meaningful benefits for corticosteroid therapy.

Dr. Pickkers cited as “must reading” an analysis of five randomized trials of corticosteroid therapy in a total of 518 patients with acute lung injury ARDS of non–COVID-19 origin. The analysis by investigators at the University of Tennessee, Memphis, concluded that treatment resulted in clinically meaningful reductions in duration of mechanical ventilation and ICU length of stay. Moreover, in the 400 patients whose steroid therapy commenced before day 14 of ARDS, there was a statistically significant 22% reduction in risk of death, compared with patients in whom corticosteroids were started later (Intensive Care Med. 2008 Jan;34[1]:61-9).

Session cochair Jan De Waele, MD, PhD, struck a cautious note, remarking, “It’s my perception that we’re using the evidence that we’ve gathered in other conditions and are now trying to apply it in COVID-19. But quality data on patients with COVID-19 itself is pretty scare, and it’s really hard to say whether this disease behaves similarly to bacterial septic shock or to other viral infections.”

“We need more information about the use of corticosteroids in COVID-19, although I think a lot of people are using it at this moment,” added Dr. De Waele, a surgical intensivist at Ghent (Belgium) University.

That being said, he asked Dr. Pickkers when he considers using corticosteroids to prevent pulmonary fibrosis.

Dr. Pickkers said that when he notices that a COVID-19 patient’s lung compliance is worsening, that stiff lung is a clue that fibrosis is occurring and is having clinical consequences. “We also measure blood procollagen, a not very sensitive but moderately specific marker of fibroproliferation. If we see an increase in this biomarker and the lung mechanics are changing, then we do treat these patients with corticosteroids,” Dr. Pickkers replied.

He and his colleagues try to start steroids before day 14 of ARDS, and they continue treatment for longer than 7 days in order to prevent a rebound inflammatory response upon treatment discontinuation. They also avoid using neuromuscular agents and engage in meticulous infection surveillance in order to minimize potential complications of corticosteroid therapy in the ICU.

Dr. Pickkers reported having no financial conflicts regarding his presentation.

Today’s top news highlights: Cancer makes COVID-19 more dangerous, treatment for heavy menstrual bleeding, and more

Article Type

Thu, 08/26/2021 - 16:06

 

Here are the stories our MDedge editors across specialties think you need to know about today:

Active cancer ups death risk for patients with COVID-19

New data show that patients with COVID-19 and progressing cancer had a significantly higher risk of 30-day mortality, compared with COVID-19–positive cancer patients who were in remission or had no evidence of cancer. Interestingly, one of the independent risk factor for death in patients with COVID-19 and cancer was treatment with hydroxychloroquine plus azithromycin. This finding, however, was of “uncertain validity due to a high risk of residual confounding; for example, patients receiving this combination were more likely to have severe disease or more likely to be hospitalized,” said Jeremy L. Warner, MD, of Vanderbilt University Medical Center in Nashville. Read more.

Two new studies indicate that social distancing successfully flattened the curve on COVID-19 hospitalizations. One study, published in JAMA, showed significantly lower numbers of observed cases versus worst-case projections in four states: Colorado, Minnesota, Ohio, and Virginia. In Minnesota, 17 days after the order, there were 361 cumulative hospitalizations, compared with a projection of 988 had no such action been taken. In a separate study measuring COVID-19 patients occupying ICU beds in Ontario and deaths among those cases, hospitals “would have rapidly exceeded ICU capacity and observed substantially higher mortality” without any physical distancing intervention. Read more.

FDA approves treatment for heavy menstrual bleeding

The Food and Drug Administration has approved a medication for the management of heavy menstrual bleeding associated with uterine fibroids in premenopausal women. The medication, marketed as Oriahnn, is an estrogen and progestin combination product that consists of elagolix, estradiol, and norethindrone acetate capsules packaged together for oral use. The most common side effects of the drug included hot flushes, headache, fatigue, and irregular vaginal bleeding. The drug’s label includes a boxed warning about a risk of strokes and blood clots, especially in women at increased risk for these events. Read more.
 


Lessons from a drive-through COVID testing center

Chris Notte, MD, and Neil Skolnik, MD, were part of a team of clinicians charged with launching a drive-through COVID-19 testing center. Their task was to get the operation up and running in 2 days. It took them 3 days. While the launch was a success, the experience taught them some lessons about the limits of medical technology and the importance of personal protective equipment. “Prior to the coronavirus pandemic, I had never considered surgical masks, face shields, and nasal swabs to be critical components of medical technology. My opinion quickly changed after opening our drive-through COVID-19 site,” they wrote. Read more.

COVID-19 effect: Prescription fills mostly down for leading drugs

Article Type
Changed
Thu, 08/26/2021 - 16:06

Prescription fills for hydroxychloroquine/chloroquine spiked right after COVID-19 was declared a national emergency in March, but use of the drugs still remains well above 2019 levels, based on data from more than 58,000 U.S. pharmacies.

Hydroxychloroquine/chloroquine are also doing better than any of the prescription drugs in the top 10 based on total claims in 2019, Muthiah Vaduganathan, MD, MPH, of Brigham and Women’s Hospital, Boston, and associates reported May 28 in a research letter in JAMA.

Prescription fills for hydroxychloroquine/chloroquine have been above 2019 levels every week since the national emergency was declared on March 13, with the high occurring during the week of March 15-21, when fills were 214% higher than the corresponding week in 2019. The lowest level in that time came during the week of April 12-18, with growth of 14.6% over 2019, the investigators said.

The drugs occupying the top 10 – amlodipine, amoxicillin, atorvastatin, gabapentin, hydrocodone-acetaminophen, levothyroxine, lisinopril, losartan, omeprazole, and sertraline – have not done as well. Losartan, the only one that hasn’t lost ground in any week since March 13, rose by almost 49% during March 15-21, but was down to a 1.7% rise by the end of the study period, they reported.

Meanwhile, the other drug touted as a treatment for COVID-19, azithromycin, has fallen farther than most of the top 10. By April 19-25, the last week of the study period, fills for the antibiotic were down 62.7%, compared with last year, the analysis showed. Only amoxicillin had dropped more (64.4%).

“The modest decline for most common long-term therapies after peak could represent reduced contact with prescribing clinicians, restricted access to pharmacies, pharmacist rationing, loss of insurance from unemployment, or replete supplies from early stockpiling,” Dr. Vaduganathan and associates wrote.

The investigators “used all-payer U.S. pharmacy data from 58,332 chain, independent, and mail-order pharmacies across 14,421 zip codes in 50 states, reflecting approximately 17 million deidentified claims,” to estimate national prescription fills, they explained.

FDA recalls extended-release metformin due to NDMA impurities

Article Type
Changed
Tue, 05/03/2022 - 15:10

The US Food and Drug Administration (FDA) has recommended voluntary recall of certain extended-release (ER) versions of metformin because testing has revealed excessive levels of N-nitrosodimethylamine (NDMA) in these products.

Metformin is the most commonly prescribed drug used to treat type 2 diabetes worldwide.

NDMA is a contaminant with the potential to be carcinogenic if there is exposure to above-acceptable levels over the long-term.

Five pharmaceutical firms in particular are being contacted by the FDA with notices (posted on the FDA website) recommending they voluntarily recall their products. At the time of writing, only one was listed, Apotex Corp and its metformin hydrochloride ER tablets, USP 500 mg.

The recall does not apply to immediate-release metformin products, the most commonly prescribed ones for diabetes, the agency stresses.

It also recommends that clinicians continue to prescribe metformin when clinically appropriate.

In late 2019, the FDA announced it had become aware of NDMA in some metformin products in other countries. The agency immediately began testing to determine whether the metformin in the US supply was at risk, as part of the ongoing investigation into nitrosamine impurities across medication types, which included recalls of hypertension and heartburn medications within the past 2 years.

By February 2020, the agency had identified very low levels of NDMA in some samples, but at that time, no FDA-tested sample of metformin exceeded the acceptable intake limit for NDMA, as reported by Medscape Medical News.

“Now that we have identified some metformin products that do not meet our standards, we’re taking action. As we have been doing since this impurity was first identified, we will communicate as new scientific information becomes available and will take further action, if appropriate,” Patrizia Cavazzoni, MD, acting director of the FDA Center for Drug Evaluation and Research, said in a press release.
 

Requests for recall apply only to affected products

The recall was instigated after the FDA became aware of reports of higher levels of NDMA in certain ER formulations of metformin through a citizen petition filed by a private laboratory. The agency confirmed unacceptable NDMA levels in some, but not all, of those lots.

“In other instances, our laboratory detected NDMA in lots that the private laboratory did not,” it notes.

The FDA says it is working closely with manufacturers of the recalled tablets to identify the source of the NDMA impurity and ensure appropriate testing is carried out.

Elevated levels of NDMA have been found in some finished-dose tablets of the ER formulations but NDMA has not been detected in samples of the metformin active pharmaceutical ingredient.

The FDA also stresses there are many other additional manufacturers that supply metformin ER products to much of the US market, and they are not being asked to recall their products.

Work is also ongoing to determine whether the drug recalls will result in shortages, and if so, the agency says it will collaborate with manufacturers to prevent or reduce any impact of shortages.

“We understand that patients may have concerns about possible impurities in their medicines and want to assure the public that we have been looking closely at this problem over many months in order to provide patients and healthcare professionals with clear and accurate answers,” Cavazzoni said.

The US Food and Drug Administration (FDA) has recommended voluntary recall of certain extended-release (ER) versions of metformin because testing has revealed excessive levels of N-nitrosodimethylamine (NDMA) in these products.

Metformin is the most commonly prescribed drug used to treat type 2 diabetes worldwide.

NDMA is a contaminant with the potential to be carcinogenic if there is exposure to above-acceptable levels over the long-term.

Five pharmaceutical firms in particular are being contacted by the FDA with notices (posted on the FDA website) recommending they voluntarily recall their products. At the time of writing, only one was listed, Apotex Corp and its metformin hydrochloride ER tablets, USP 500 mg.

The recall does not apply to immediate-release metformin products, the most commonly prescribed ones for diabetes, the agency stresses.

It also recommends that clinicians continue to prescribe metformin when clinically appropriate.

In late 2019, the FDA announced it had become aware of NDMA in some metformin products in other countries. The agency immediately began testing to determine whether the metformin in the US supply was at risk, as part of the ongoing investigation into nitrosamine impurities across medication types, which included recalls of hypertension and heartburn medications within the past 2 years.

By February 2020, the agency had identified very low levels of NDMA in some samples, but at that time, no FDA-tested sample of metformin exceeded the acceptable intake limit for NDMA, as reported by Medscape Medical News.

“Now that we have identified some metformin products that do not meet our standards, we’re taking action. As we have been doing since this impurity was first identified, we will communicate as new scientific information becomes available and will take further action, if appropriate,” Patrizia Cavazzoni, MD, acting director of the FDA Center for Drug Evaluation and Research, said in a press release.
 

Requests for recall apply only to affected products

The recall was instigated after the FDA became aware of reports of higher levels of NDMA in certain ER formulations of metformin through a citizen petition filed by a private laboratory. The agency confirmed unacceptable NDMA levels in some, but not all, of those lots.

“In other instances, our laboratory detected NDMA in lots that the private laboratory did not,” it notes.

The FDA says it is working closely with manufacturers of the recalled tablets to identify the source of the NDMA impurity and ensure appropriate testing is carried out.

Elevated levels of NDMA have been found in some finished-dose tablets of the ER formulations but NDMA has not been detected in samples of the metformin active pharmaceutical ingredient.

APA, others lobby to make COVID-19 telehealth waivers permanent

The American Psychiatric Association (APA) is calling on Congress to permanently lift restrictions that have allowed unfettered delivery of telehealth services during the COVID-19 pandemic, which experts say has been a boon to patients and physicians alike.

Dr. Peter Yellowlees

“We ask Congress to extend the telehealth waiver authority under COVID-19 beyond the emergency and to study its impact while doing so,” said APA President Jeffrey Geller, MD, in a May 27 video briefing with congressional staff and reporters.

The APA is also seeking to make permanent certain waivers granted by the Centers for Medicare & Medicaid Services on April 30, including elimination of geographic restrictions on behavioral health and allowing patients be seen at home, said Dr. Geller.

The APA also is asking for the elimination of the rule that requires clinicians to have an initial face-to-face meeting with patients before they can prescribe controlled substances, Dr. Geller said. The Drug Enforcement Administration waived that requirement, known as the Ryan Haight Act, on March 17 for the duration of the national emergency.

Telemedicine has supporters on both sides of the aisle in Congress, including Rep. Paul Tonko (D-N.Y.) who said at the APA briefing he would fight to make the waivers permanent.

“The expanded use of telehealth has enormous potential during normal times as well, especially in behavioral health,” said Mr. Tonko. “I am pushing fiercely for these current flexibilities to be extended for a reasonable time after the public health emergency so that we can have time to evaluate which should be made permanent,” he said.

Dr. Geller, other clinicians, and advocates in the briefing praised CMS for facilitating telepsychiatry for Medicare. That follows in the footsteps of most private insurers, who have also relaxed requirements into the summer, according to the Medical Group Management Association.
 

Game changer

The Medicare waivers “have dramatically changed the entire scene for someone like myself as a clinician to allow me to see my patients in a much easier way,” said Peter Yellowlees, MBBS, MD, chief wellness officer, University of California Davis Health. Within 2 weeks in March, the health system converted almost all of its regular outpatient visits to telemedicine, he said.

Dr. Yellowlees added government still needs to address, what he called, outdated HIPAA regulations that ban certain technologies.

“It makes no sense that I can talk to someone on an iPhone, but the moment I talk to them on FaceTime, it’s illegal,” said Dr. Yellowlees, a former president of the American Telemedicine Association.

Dr. Geller said that “psychiatric care provided by telehealth is as effective as in-person psychiatric services,” adding that “some patients prefer telepsychiatry because of its convenience and as a means of reducing stigma associated with seeking help for mental health.”

Shabana Khan, MD, a child psychiatrist and director of telepsychiatry at New York University Langone Health, said audio and video conferencing are helping address a shortage and maldistribution of child and adolescent psychiatrists.

Americans’ mental health is suffering during the pandemic. The U.S. Census Bureau recently released data showing that half of those surveyed reported depressed mood and that one-third are reporting anxiety, depression, or both, as reported by the Washington Post.

“At this very time that anxiety, depression, substance use, and other mental health problems are rising, our nation’s already strained mental health system is really being pushed to the brink,” said Jodi Kwarciany, manager for mental health policy for the National Alliance on Mental Illness, during the briefing.

Telemedicine can help “by connecting people to providers at the time and the place and using the technology that works best for them,” she said, adding that NAMI would press policymakers to address barriers to access.

The clinicians on the briefing said they’ve observed that some patients are more comfortable with video or audio interactions than with in-person visits.
 

 

 

Increased access to care

Telepsychiatry seems to be convincing some to reconsider therapy, since they can do it at home, said Dr. Yellowlees. The technology is a way of “enlarging the tent for us as a profession and providing more care,” he said.

For instance, he said, he has been able to consult by phone and video with several patients who receive care through the Indian Health Service who had not be able to get into the physical clinic.

Dr. Yellowlees said video sessions also may encourage patients to be more, not less, talkative. “Video is actually counterintuitively a very intimate experience,” he said, in part because of the perceived distance and people’s tendency to be less inhibited on technology platforms.“It’s less embarrassing,” he said. “If you’ve got really dramatic, difficult, traumatic things to talk about, it’s slightly easier to talk to someone who’s slightly further apart from you on video,” said Dr. Yellowlees.

“Individuals who have a significant amount of anxiety may actually feel more comfortable with the distance that this technology affords,” agreed Dr. Khan. She said telemedicine had made sessions more comfortable for some of her patients with autism spectrum disorder.

Dr. Geller said audio and video have been important to his practice during the pandemic. One of his patients never leaves the house and does not use computers. “He spends his time sequestered at home listening to records on his record player,” said Dr. Geller. But he’s been amenable to phone sessions. “What I’ve found with him, and I’ve found with several other patients, is that they actually talk more easily when they’re not face to face,” he said.
 

Far fewer no-shows

Another plus for his New England–based practice during the last few months: patients have not been anxious about missing sessions because of the weather. The clinicians all noted that telepsychiatry seemed to reduce missed visits.

Dr. Yellowlees said that no-show rates had decreased by half at UC Davis. “That means no significant loss of income,” during the pandemic, he said.

“The no-show rate is incredibly low, particularly because when you call the patients and they don’t remember they had an appointment, you have the appointment anyway, most of the time,” said Dr. Geller.

For Dr. Khan, being able to conduct audio and video sessions during the pandemic has meant keeping up continuity of care.

As a result of the pandemic, many college students in New York City had to go home – often to another state. The waivers granted by New York’s Medicaid program and other insurers have allowed Dr. Khan to continue care for these patients.

The NYU clinic also operates day programs in rural areas 5 hours from the city. Dr. Khan recently evaluated a 12-year-old girl with significant anxiety and low mood, both of which had worsened.

“She would not have been able to access care otherwise,” said Dr. Khan. And for rural patients who do not have access to broadband or smartphones, audio visits “have been immensely helpful,” she said.

Dr. Khan, Dr. Geller, and Dr. Yellowlees have disclosed no relevant financial relationships.

COVID-19 may increase risk of preterm birth and cesarean delivery

Hospitalized pregnant women with COVID-19 may be at increased risk for preterm birth and cesarean delivery, data from northern Italy suggest.

Herjua/Thinkstock

Among 57 hospitalized patients with SARS-CoV-2 infection who underwent vaginal or cesarean delivery, 7 had spontaneous preterm or respiratory-indicated preterm delivery, a rate of 12%, according to a study published in Obstetrics & Gynecology. For comparison, 7% of patients had preterm delivery in 2019, researchers reported “We also noted a high cesarean delivery rate in the study population (39% vs. 27% in the same area in 2019), mainly as a result of maternal respiratory-indicated urgent delivery,” wrote Valeria M. Savasi, MD, PhD, of the University of Milan and Luigi Sacco Hospital, also in Milan, and colleagues.

Data do not indicate that pregnant women are more susceptible to severe COVID-19 infection, nor have studies suggested an increased risk of miscarriage, congenital anomalies, or early pregnancy loss in pregnant patients with COVID-19, the authors wrote. Studies have described an increased risk of preterm birth, however.

To study clinical features of maternal SARS-CoV-2 infection and potential factors associated with severe disease and iatrogenic delivery, Dr. Savasi and colleagues conducted a prospective study of 77 women with laboratory-confirmed SARS-CoV-2 infection who were admitted during pregnancy or the immediate postpartum period in 12 maternity hospitals in northern Italy between Feb. 23 and March 28, 2020.

The investigators classified patients as having severe disease if they underwent urgent delivery based on maternal respiratory function or if they were admitted to an ICU or subintensive care department. In all, 14 patients (18%) were classified as having severe disease.

“Three patients were intubated after emergency cesarean delivery performed for maternal deterioration, and one patient underwent extracorporeal membrane oxygenation,” Dr. Savasi and colleagues reported. The results are consistent with epidemiologic data in the nonpregnant population with COVID-19 disease.

Of 11 patients with severe disease who underwent urgent delivery for respiratory compromise, 6 had significant postpartum improvement in clinical conditions. No maternal deaths occurred.

“Increased BMI [body mass index] was a significant risk factor for severe disease,” Dr. Savasi and colleagues wrote. “Fever and dyspnea on admission were symptoms significantly associated with subsequent severe maternal respiratory deterioration.”

Most patients (65%) were admitted during the third trimester, and 20 patients were still pregnant at discharge.

“Nine newborns were admitted to the neonatal intensive care unit,” the authors wrote. “Interestingly, besides prematurity, fetal oxygenation and well-being at delivery were not apparently affected by the maternal acute conditions.” Three newborns with vaginal delivery and one with cesarean delivery tested positive for SARS-CoV-2. The newborns may have been infected after delivery, Dr. Savasi and colleagues added. For all newborns, rooming-in and breastfeeding were performed, and none developed respiratory symptoms.

Criteria for hospital admission and therapeutic protocols may have varied between hospitals, the authors noted. In addition, the study included 12 patients who were asymptomatic and admitted for obstetric indications. These patients were tested for SARS-CoV-2 because of contact with an infected individual. Most patients were symptomatic, however, which explains the high rate of maternal severe outcomes. Hospitals have since adopted a universal SARS-CoV-2 screening policy for hospitalized pregnant patients.

Kristina Adams Waldorf, MD, professor of obstetrics and gynecology at the University of Washington, Seattle, commented in an interview that Savasi et al. describe one of the larger COVID-19 in pregnancy cohorts to date with rates of severe disease and delivery for respiratory compromise, which is remarkably similar to Washington state (severe disease, 18% vs. nearly 15%; delivery for respiratory compromise, 16% vs. 20%). As in Washington state, Italian women with a higher prepregnancy BMI were overrepresented in the severe disease group.

“Data are beginning to emerge that identify women who were overweight or obese prior to pregnancy as a high risk group for developing severe COVID-19. These data are similar to known associations between obesity and critical illness in pregnancy during the 2009 ‘swine flu’ (influenza A virus, H1N1) pandemic,” she said.

“This study and others indicate that the late second and third trimesters may be a time when women are more likely to be symptomatic from COVID-19. It remains unclear if women in the first trimester are protected from severe COVID-19 outcomes or have outcomes similar to nonpregnant women,” concluded Dr. Waldorf.

One study author disclosed receiving funds from Lo Li Pharma and Zambongroup. The other authors did not report any potential conflicts of interest. Dr. Waldorf said she had no relevant financial disclosures.

Of 11 patients with severe disease who underwent urgent delivery for respiratory compromise, 6 had significant postpartum improvement in clinical conditions. No maternal deaths occurred.

“Increased BMI [body mass index] was a significant risk factor for severe disease,” Dr. Savasi and colleagues wrote. “Fever and dyspnea on admission were symptoms significantly associated with subsequent severe maternal respiratory deterioration.”

Most patients (65%) were admitted during the third trimester, and 20 patients were still pregnant at discharge.

“Nine newborns were admitted to the neonatal intensive care unit,” the authors wrote. “Interestingly, besides prematurity, fetal oxygenation and well-being at delivery were not apparently affected by the maternal acute conditions.” Three newborns with vaginal delivery and one with cesarean delivery tested positive for SARS-CoV-2. The newborns may have been infected after delivery, Dr. Savasi and colleagues added. For all newborns, rooming-in and breastfeeding were performed, and none developed respiratory symptoms.

Criteria for hospital admission and therapeutic protocols may have varied between hospitals, the authors noted. In addition, the study included 12 patients who were asymptomatic and admitted for obstetric indications. These patients were tested for SARS-CoV-2 because of contact with an infected individual. Most patients were symptomatic, however, which explains the high rate of maternal severe outcomes. Hospitals have since adopted a universal SARS-CoV-2 screening policy for hospitalized pregnant patients.

Kristina Adams Waldorf, MD, professor of obstetrics and gynecology at the University of Washington, Seattle, commented in an interview that Savasi et al. describe one of the larger COVID-19 in pregnancy cohorts to date with rates of severe disease and delivery for respiratory compromise, which is remarkably similar to Washington state (severe disease, 18% vs. nearly 15%; delivery for respiratory compromise, 16% vs. 20%). As in Washington state, Italian women with a higher prepregnancy BMI were overrepresented in the severe disease group.

“Data are beginning to emerge that identify women who were overweight or obese prior to pregnancy as a high risk group for developing severe COVID-19. These data are similar to known associations between obesity and critical illness in pregnancy during the 2009 ‘swine flu’ (influenza A virus, H1N1) pandemic,” she said.

“This study and others indicate that the late second and third trimesters may be a time when women are more likely to be symptomatic from COVID-19. It remains unclear if women in the first trimester are protected from severe COVID-19 outcomes or have outcomes similar to nonpregnant women,” concluded Dr. Waldorf.

One study author disclosed receiving funds from Lo Li Pharma and Zambongroup. The other authors did not report any potential conflicts of interest. Dr. Waldorf said she had no relevant financial disclosures.

Hospitalized pregnant women with COVID-19 may be at increased risk for preterm birth and cesarean delivery, data from northern Italy suggest.

Among 57 hospitalized patients with SARS-CoV-2 infection who underwent vaginal or cesarean delivery, 7 had spontaneous preterm or respiratory-indicated preterm delivery, a rate of 12%, according to a study published in Obstetrics & Gynecology. For comparison, 7% of patients had preterm delivery in 2019, researchers reported “We also noted a high cesarean delivery rate in the study population (39% vs. 27% in the same area in 2019), mainly as a result of maternal respiratory-indicated urgent delivery,” wrote Valeria M. Savasi, MD, PhD, of the University of Milan and Luigi Sacco Hospital, also in Milan, and colleagues.

Data do not indicate that pregnant women are more susceptible to severe COVID-19 infection, nor have studies suggested an increased risk of miscarriage, congenital anomalies, or early pregnancy loss in pregnant patients with COVID-19, the authors wrote. Studies have described an increased risk of preterm birth, however.

To study clinical features of maternal SARS-CoV-2 infection and potential factors associated with severe disease and iatrogenic delivery, Dr. Savasi and colleagues conducted a prospective study of 77 women with laboratory-confirmed SARS-CoV-2 infection who were admitted during pregnancy or the immediate postpartum period in 12 maternity hospitals in northern Italy between Feb. 23 and March 28, 2020.

The investigators classified patients as having severe disease if they underwent urgent delivery based on maternal respiratory function or if they were admitted to an ICU or subintensive care department. In all, 14 patients (18%) were classified as having severe disease.

“Three patients were intubated after emergency cesarean delivery performed for maternal deterioration, and one patient underwent extracorporeal membrane oxygenation,” Dr. Savasi and colleagues reported. The results are consistent with epidemiologic data in the nonpregnant population with COVID-19 disease.

Of 11 patients with severe disease who underwent urgent delivery for respiratory compromise, 6 had significant postpartum improvement in clinical conditions. No maternal deaths occurred.

Testing the limits of medical technology

Article Type
Changed
Thu, 08/26/2021 - 16:06

On March 9 my team was given a directive by the chief medical officer of our health system. We were charged with opening a drive-through COVID-19 testing center for our community in just 2 days’ time. It seemed like an impossible task, involving the mobilization of people, processes, and technology at a scale and speed we had never before achieved. It turned out getting this done was impossible. In spite of our best efforts, we failed to meet the deadline – it actually took us 3 days. Still, by March 12, we had opened the doors on the first community testing site in our area and gained the attention of local and national news outlets for our accomplishment.

Dr. Chris Notte and Dr. Neil Skolnik

Now more than 2 months later, I’m quite proud of what our team was able to achieve for the health system, but I’m still quite frustrated at the state of COVID-19 testing nationwide – there’s simply not enough available, and there is tremendous variability in the reliability of the tests. In this column, we’d like to highlight some of the challenges we’ve faced and reflect on how the shortcomings of modern technology have once again proven that medicine is both a science and an art.
 

Our dangerous lack of preparation

Prior to the coronavirus pandemic, I had never considered surgical masks, face shields, and nasal swabs to be critical components of medical technology. My opinion quickly changed after opening our drive-through COVID-19 site. I now have a much greater appreciation for the importance of personal protective equipment and basic testing supplies.

I was shocked by how difficult obtaining it has been during the past few months. It seems that no one anticipated the possibility of a pandemic on this grand a scale, so stockpiles of equipment were depleted quickly and couldn’t be replenished. Also, most manufacturing occurs outside the United States, which creates additional barriers to controlling the supply chain. One need not look far to find stories of widespread price-gouging, black market racketeering, and even hijackings that have stood in the way of accessing the necessary supplies. Sadly, the lack of equipment is far from the only challenge we’ve faced. In some cases, it has been a mistrust of results that has prevented widespread testing and mitigation.
 

The risks of flying blind

When President Trump touted the introduction of a rapid COVID-19 test at the end of March, many people were excited. Promising positive results in as few as 5 minutes, the assay was granted an Emergency Use Authorization (EUA) by the Food and Drug Administration in order to expedite its availability in the market. According to the FDA’s website, an EUA allows “unapproved medical products or unapproved uses of approved medical products to be used in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions.” This rapid (though untested) approval was all that many health care providers needed to hear – immediately hospitals and physicians scrambled to get their hands on the testing devices. Unfortunately, on May 14th, the FDA issued a press release that raised concerns about that same test because it seemed to be reporting a high number of false-negative results. Just as quickly as the devices had been adopted, health care providers began backing away from them in favor of other assays, and a serious truth about COVID-19 testing was revealed: In many ways, we’re flying blind.

Laboratory manufacturers have been working overtime to create assays for SARS-CoV-2 (the coronavirus that causes COVID-19) and have used different technologies for detection. The most commonly used are polymerase chain reaction (PCR) tests. In these assays, viral RNA is converted to DNA by reverse transcriptase, then amplified through the addition of primers that enable detection. PCR technology has been available for years and is a reliable method for identifying DNA and RNA, but the required heating and cooling process takes time and results can take several hours to return. To address this and expedite testing, other methods of detection have been tried, such as the loop-mediated isothermal amplification (LAMP) technique employed by the rapid assay mentioned above. Regardless of methodology, all laboratory tests have one thing in common: None of them is perfect.

Every assay has a different level of reliability. When screening for a disease such as COVID-19, we are particularly interested in a test’s sensitivity (that is, it’s ability to detect disease); we’d love such a screening test to be 100% sensitive and thereby not miss a single case. In truth, no test’s sensitivity is 100%, and in this particular case even the best assays only score around 98%. This means that out of every 100 patients with COVID-19 who are evaluated, two might test negative for the virus. In a pandemic this can have dire consequences, so health care providers – unable to fully trust their instruments – must employ clinical acumen and years of experience to navigate these cloudy skies. We are hopeful that additional tools will complement our current methods, but with new assays also come new questions.
 

Is anyone safe?

We receive regular questions from physicians about the value of antibody testing, but it’s not yet clear how best to respond. While the assays seem to be reliable, the utility of the results are still ill defined. Antibodies to SARS-CoV-2 (both IgG and IgM) appear to peak about 2-3 weeks after symptom onset, but we don’t yet know if the presence of those antibodies confers long-term immunity. Therefore, patients should not use the information to change their masking or social-distancing practices, nor should they presume that they are safe from becoming reinfected with COVID-19. While new research looks promising, there are still too many unknowns to be able to confidently reassure providers or patients of the true value of antibody testing. This underscores our final point: Medicine remains an art.

As we are regularly reminded, we’ll never fully anticipate the challenges or barriers to success, and technology will never replace the value of clinical judgment and human experience. While the situation is unsettling in many ways, we are reassured and encouraged by the role we still get to play in keeping our patients healthy in this health care crisis, and we’ll continue to do so through whatever the future holds.

Scientific doubt tempers COVID-19 vaccine optimism

Article Type
Changed
Thu, 08/26/2021 - 16:06

US government and industry projections that a COVID-19 vaccine will be ready by this fall or even January would take compressing what usually takes at least a decade into months, with little room for error or safety surprises.

“If all the cards fall into the right place and all the stars are aligned, you definitely could get a vaccine by December or January,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said last week.

But Fauci said a more realistic timeline is still 12 to 18 months, and experts interviewed by Medscape Medical News agree. They say that although recent developments are encouraging, history and scientific reason say the day when a COVID-19 vaccine is widely available will not come this year and may not come by the end of 2021.

The encouraging signals come primarily from two recent announcements: the $1.2 billion United States backing last week of one vaccine platform and the announcement on May 18 that the first human trials of another have produced some positive phase 1 results.
 

Recent developments

On May 21, the US Department of Health and Human Services (HHS) under “Operation Warp Speed” announced that the US will give AstraZeneca $1.2 billion “to make available at least 300 million doses of a coronavirus vaccine called AZD1222, with the first doses delivered as early as October 2020.”

On May 18, the Massachusetts-based biotechnology company Moderna announced that phase 1 clinical results showed that its vaccine candidate, which uses a new messenger RNA (mRNA) technology, appeared safe. Eight participants in the human trials were able to produce neutralizing antibodies that researchers believe are important in developing protection from the virus.

Moderna Chief Medical Officer Tal Zaks, MD, PhD told CNN that if the vaccine candidate does well in phase 2, “it could be ready by January 2021.”

The two candidates are among 10 in clinical trials for the SARS-CoV-2 virus, according to the World Health Organization (WHO). The AstraZeneca/ AZD1222 candidate (also called ChAdOx1 nCoV-19, in collaboration with the University of Oxford) has entered phase 2/3.

Moderna’s candidate and another being developed in Beijing, China, are in phase 2, WHO reports. As of yesterday, 115 other candidates are in preclinical evaluation.

Maria Elena Bottazzi, PhD, associate dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, Texas, told Medscape Medical News it’s important to realize that, in the case of the $1.2 billion US investment, “what they’re talking about is manufacturing.”

The idea, she said, is to pay AstraZeneca up front so that manufacturing can start before it is known whether the vaccine candidate is safe or effective, the reverse of how the clinical trial process usually works.

That way, if the candidate is deemed safe and effective, time is not lost by then deciding how to make it and distribute it.

By the end of this year, she said, “Maybe we will have many vaccines made and stored in a refrigerator somewhere. But between now and December, there’s absolutely no way you can show efficacy of the vaccine at the same time you confirm that it’s safe.”
 

 

 

“Take these things with a grain of salt”

Animal testing for the AstraZeneca candidate, made in partnership with the University of Oxford in the United Kingdom, has yielded lackluster results, according to results on the preprint server BioRxiv, which have not been peer-reviewed.

“The results were not bad, but they were not gangbusters,” Bottazzi said. The results show the vaccine offered only partial protection.

“Partial protection is better than no protection,” she noted. “You have to take these things with a grain of salt. We don’t know what’s going to happen in humans.”

As for the Moderna candidate, Bottazzi said, “the good news is they found an appropriate safety profile. But from an eight-person group to make the extrapolation that they have efficacy — it’s unrealistic.”

Nicole Lurie, MD, MSPH, is senior adviser to the CEO for the Coalition for Epidemic Preparedness Innovation (CEPI), a nongovernmental organization funded by the Wellcome Trust, the Bill and Melinda Gates Foundation, the European Commission, and eight countries (Australia, Belgium, Canada, Ethiopia, Germany, Japan, Norway, and the United Kingdom) charged with supporting development of vaccines for pathogens on WHO’s priority list.

She and her colleagues write in a paper published online in the New England Journal of Medicine on March 30 that “it typically takes multiple candidates and many years to produce a licensed vaccine.”

The fastest time for developing a vaccine to date is 4 years, for the mumps vaccine, licensed in 1967.

As to whether she would expect a rollout of any vaccine by the end of the year, Lurie told Medscape Medical News, “If everything goes according to plan in every way, shape or form, well then maybe you can get there. But I wouldn’t hold my breath.”

Lurie and her colleagues write that “it’s far from certain that these new platforms will be scalable or that existing capacity can provide sufficient quantities of vaccine fast enough.”

On a call with reporters today, leaders of some of the words largest pharmaceutical companies said that one of the key bottlenecks is the sheer number of vials needed in order to distribute billions of doses of a successful vaccine.

Pfizer CEO Albert Bourla, DVM, PhD, said, “Typically we are producing vaccines in single-dose vials. We are exploring with governments right now if it would be more convenient if there were 5-dose vials or 10-dose vials. I think we can resolve a significant part of the bottleneck.”

Despite the challenges, experts interviewed for this article agree that it will be possible to make a vaccine for COVID-19. They don’t expect attempts to meet the same complications that HIV researchers have seen over decades as the virus continues to confound with mutations.

Fred Ledley, MD, director of the Center for Integration of Science and Industry at Bentley University in Waltham, Massachusetts, told Medscape Medical News, “There doesn’t appear to be anything terribly diabolical about this virus. The mutation rate doesn’t appear to be anything like HIV. It appears to have some big, ugly proteins on the surface, which is good for vaccines — proteins with a lot of physical features look distinguishable from healthy cells. Signs all point to that it should be possible to make a vaccine.”
 

 

 

History raises safety concerns

However, Ledley said, “The idea of doing it in 6 months is largely unrealistic.”

He says 18 months is more realistic, primarily because of the sheer number of people that would have to be enrolled in a phase 3 study to truly test whether the endpoints are being met.

Vaccines are given to healthy volunteers. If safety signals arise, they may not be apparent until massive numbers of people are tested in phase 3.

“You’re never going to see the rates cut to 0%, but to see the difference between 10 people getting sick and seven people getting sick, takes very, very large numbers,” Ledley said. “There’s no way that can be done in 6 months. You’re talking about tens of thousands of people enrolled.”

He notes at this point it’s unclear what the endpoints will be and what the safety thresholds will be after consideration of risks and benefit.

Another big question for Ledley: “We don’t know what type of immunity we need to protect us against the virus. Do you just need the antibodies in your blood or do you need cells that are primed to attack the virus? Is it more of a chemical clearance or do the cells need to physically go in and digest the virus?”

History also points to the need for rigorous safety precautions that scientists fear could be compromised as trial phases overlap and processes are run in parallel instead of one step at a time.

An early batch of the Salk vaccine for polio in 1955, for example, turned out to be contaminated and caused paralysis in some children and 10 deaths, he points out.

CEPI’s Lurie adds that early candidates for another coronavirus, severe acute respiratory syndrome (SARS), “caused a reaction in the lungs that was very dangerous” before development was halted.

She also pointed to previous findings that a vaccine for dengue fever could worsen the disease in some people through a phenomenon called antibody-dependent enhancement.

Lurie and colleagues write in their paper that “it’s critical that vaccines also be developed using the tried-and-true methods, even if they may take longer to enter clinical trials or to result in large numbers of doses.”
 

Live attenuated vaccine

Raul Andino, PhD, a virologist at the University of California San Francisco, is among the scientists working with a tried-and-true method ­— a live attenuated vaccine — and he told Medscape Medical News he’s predicting it will take 2 years to develop.

He said it is cheaper to produce because scientists just have to learn how to grow the virus. Because the technology is already proven, a live attenuated vaccine could be rapidly produced on a worldwide scale.

The hope is also that a live attenuated vaccine would be given once in a lifetime and therefore be more affordable, especially in poorer countries.

“While a Moderna vaccine might be good for Europe and the United States,” he said, “It’s not going to be good for Africa, India, Brazil.”

Andino said, “I would bet money” that the front-runner vaccines so far will not be one-time vaccines.

He points out that most of the vaccine candidates are trying to protect people from disease. While there’s nothing wrong with that, he said, “In my opinion that is the lower-hanging fruit.”

“In my mind we need something that interrupts the chain of transmission and induces protection,” Andino said, important for developing herd immunity.

The reason this type of approach takes longer is because you are introducing a weakened form of the virus to the body and you have to make sure it doesn’t cause disease, not just in a small test population, but in populations who may be more susceptible to the disease, Andino said.
 

 

 

A call for unified strategies

Universities, countries, international consortiums, and public-private partnerships are all racing to find several safe and effective vaccines as no one entity will likely be able to provide the global solution.

Some of the efforts involve overlap of entities but with different focuses.

Along with “Operation Warp Speed” and CEPI, other collaborations include Gavi the Vaccine Alliance, whose core partners include WHO, UNICEF, the World Bank, and the Gates Foundation; and “Accelerating Therapeutic Interventions and Vaccines (ACTIV) partnership,” led by the National Institutes of Health.

Industry partners in ACTIV (18 biopharmaceutical companies), according to a May 18 article published online in the Journal of the American Medical Association, have said they will contribute their respective clinical trial capacities, regardless of which agent is studied.

Some, however, have called for more streamlining of efforts.

“Ideally we’d be working together,” Lurie told Medscape Medical News.

“I’m hopeful we will find ways to collaborate scientifically,” she said. “The US government’s responsibility is to make doses for the US. CEPI’s responsibility is to make doses for the world. A big focus of CEPI is to make sure we have manufacturing capacity outside of the US so those doses can be available to the world and they don’t get seized by wealthy countries.”

Bottazzi, Ledley, Lurie, and Andino report no relevant financial relationships.

US government and industry projections that a COVID-19 vaccine will be ready by this fall or even January would take compressing what usually takes at least a decade into months, with little room for error or safety surprises.

“If all the cards fall into the right place and all the stars are aligned, you definitely could get a vaccine by December or January,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said last week.

But Fauci said a more realistic timeline is still 12 to 18 months, and experts interviewed by Medscape Medical News agree. They say that although recent developments are encouraging, history and scientific reason say the day when a COVID-19 vaccine is widely available will not come this year and may not come by the end of 2021.

The encouraging signals come primarily from two recent announcements: the $1.2 billion United States backing last week of one vaccine platform and the announcement on May 18 that the first human trials of another have produced some positive phase 1 results.
 

Recent developments

On May 21, the US Department of Health and Human Services (HHS) under “Operation Warp Speed” announced that the US will give AstraZeneca $1.2 billion “to make available at least 300 million doses of a coronavirus vaccine called AZD1222, with the first doses delivered as early as October 2020.”

On May 18, the Massachusetts-based biotechnology company Moderna announced that phase 1 clinical results showed that its vaccine candidate, which uses a new messenger RNA (mRNA) technology, appeared safe. Eight participants in the human trials were able to produce neutralizing antibodies that researchers believe are important in developing protection from the virus.

Moderna Chief Medical Officer Tal Zaks, MD, PhD told CNN that if the vaccine candidate does well in phase 2, “it could be ready by January 2021.”

The two candidates are among 10 in clinical trials for the SARS-CoV-2 virus, according to the World Health Organization (WHO). The AstraZeneca/ AZD1222 candidate (also called ChAdOx1 nCoV-19, in collaboration with the University of Oxford) has entered phase 2/3.

Moderna’s candidate and another being developed in Beijing, China, are in phase 2, WHO reports. As of yesterday, 115 other candidates are in preclinical evaluation.

Maria Elena Bottazzi, PhD, associate dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, Texas, told Medscape Medical News it’s important to realize that, in the case of the $1.2 billion US investment, “what they’re talking about is manufacturing.”

The idea, she said, is to pay AstraZeneca up front so that manufacturing can start before it is known whether the vaccine candidate is safe or effective, the reverse of how the clinical trial process usually works.

That way, if the candidate is deemed safe and effective, time is not lost by then deciding how to make it and distribute it.

By the end of this year, she said, “Maybe we will have many vaccines made and stored in a refrigerator somewhere. But between now and December, there’s absolutely no way you can show efficacy of the vaccine at the same time you confirm that it’s safe.”
 

 

 

“Take these things with a grain of salt”

Animal testing for the AstraZeneca candidate, made in partnership with the University of Oxford in the United Kingdom, has yielded lackluster results, according to results on the preprint server BioRxiv, which have not been peer-reviewed.

“The results were not bad, but they were not gangbusters,” Bottazzi said. The results show the vaccine offered only partial protection.

“Partial protection is better than no protection,” she noted. “You have to take these things with a grain of salt. We don’t know what’s going to happen in humans.”

As for the Moderna candidate, Bottazzi said, “the good news is they found an appropriate safety profile. But from an eight-person group to make the extrapolation that they have efficacy — it’s unrealistic.”

Nicole Lurie, MD, MSPH, is senior adviser to the CEO for the Coalition for Epidemic Preparedness Innovation (CEPI), a nongovernmental organization funded by the Wellcome Trust, the Bill and Melinda Gates Foundation, the European Commission, and eight countries (Australia, Belgium, Canada, Ethiopia, Germany, Japan, Norway, and the United Kingdom) charged with supporting development of vaccines for pathogens on WHO’s priority list.

She and her colleagues write in a paper published online in the New England Journal of Medicine on March 30 that “it typically takes multiple candidates and many years to produce a licensed vaccine.”

The fastest time for developing a vaccine to date is 4 years, for the mumps vaccine, licensed in 1967.

As to whether she would expect a rollout of any vaccine by the end of the year, Lurie told Medscape Medical News, “If everything goes according to plan in every way, shape or form, well then maybe you can get there. But I wouldn’t hold my breath.”

Lurie and her colleagues write that “it’s far from certain that these new platforms will be scalable or that existing capacity can provide sufficient quantities of vaccine fast enough.”

On a call with reporters today, leaders of some of the words largest pharmaceutical companies said that one of the key bottlenecks is the sheer number of vials needed in order to distribute billions of doses of a successful vaccine.

Pfizer CEO Albert Bourla, DVM, PhD, said, “Typically we are producing vaccines in single-dose vials. We are exploring with governments right now if it would be more convenient if there were 5-dose vials or 10-dose vials. I think we can resolve a significant part of the bottleneck.”

Despite the challenges, experts interviewed for this article agree that it will be possible to make a vaccine for COVID-19. They don’t expect attempts to meet the same complications that HIV researchers have seen over decades as the virus continues to confound with mutations.

Fred Ledley, MD, director of the Center for Integration of Science and Industry at Bentley University in Waltham, Massachusetts, told Medscape Medical News, “There doesn’t appear to be anything terribly diabolical about this virus. The mutation rate doesn’t appear to be anything like HIV. It appears to have some big, ugly proteins on the surface, which is good for vaccines — proteins with a lot of physical features look distinguishable from healthy cells. Signs all point to that it should be possible to make a vaccine.”
 

 

 

History raises safety concerns

However, Ledley said, “The idea of doing it in 6 months is largely unrealistic.”

He says 18 months is more realistic, primarily because of the sheer number of people that would have to be enrolled in a phase 3 study to truly test whether the endpoints are being met.

Vaccines are given to healthy volunteers. If safety signals arise, they may not be apparent until massive numbers of people are tested in phase 3.

“You’re never going to see the rates cut to 0%, but to see the difference between 10 people getting sick and seven people getting sick, takes very, very large numbers,” Ledley said. “There’s no way that can be done in 6 months. You’re talking about tens of thousands of people enrolled.”

COVID-19: Putting distance between projection and reality

Article Type
Changed
Thu, 08/26/2021 - 16:06

When it comes to COVID-19, studies show that social distancing flattened the curve.

Cumulative hospitalizations in four states with stay-at-home orders were well short of the projected exponential growth curves, Soumya Sen, PhD, of the University of Minnesota, Minneapolis, and associates reported May 27 in a research letter in JAMA. All states were observed through April 28.

The deviations between observed cases and worst-case projections in the four states – Colorado, Minnesota, Ohio, and Virginia – all began within 8-10 days of the stay-at-home orders. In Minnesota, 17 days after the order, there were 361 cumulative hospitalizations, compared with a projection of 988 had no such action been taken. In Virginia, the corresponding numbers were 1,048 observed and 2,335 projected, they reported.

“Observed hospitalizations consistently fell outside of the 95% prediction bands of the projected exponential growth curve,” Dr. Sen and associates noted.

In a separate Canadian study measuring COVID-19 patients occupying ICU beds in Ontario and deaths among those cases, hospitals “would have rapidly exceeded ICU capacity and observed substantially higher mortality” without any physical distancing intervention, Ashleigh R. Tuite, PhD, MPH, of the University of Toronto and associates wrote May 27 in a letter in Annals of Internal Medicine.

Their model, based on a 70% reduction in physical contacts for March 19–May 3, projected 2.0 cases per 100,000 population with physical distancing and 37.4 per 100,000 without. Deaths among those ICU patients were projected at 2.5 per 100,000 with distancing and 12.7 per 100,000 without intervention, they reported.

“Our modeling also shows the challenges associated with relaxation of physical distancing measures without a concomitant increase in other public health measures. Specifically, when the number of contacts between persons returns to more than 50% of normal, we expect disease activity to resurge rapidly and ICUs to quickly reach capacity,” they wrote.

The study published in JAMA used publicly available data from the University of Minnesota COVID-19 Hospitalization Project, which is partially funded by the University of Minnesota Office of Academic Clinical Affairs and United Health Foundation.
