Bayer has voluntarily recalled batches of its Lotrimin and Tinactin products because of benzene detected in some samples, according to an Oct. 1 company announcement, available on the Food and Drug Administration website. “It is important to note that Bayer’s decision to voluntarily recall these products is a precautionary measure and that the levels detected are not expected to cause adverse health consequences in consumers,” the announcement said.

Benzene is classified as a human carcinogen present in the environment from both natural sources and human activity, and it has been shown to cause cancer with long-term exposure.

The products included in the recall – all in aerosol spray cans – are unexpired Lotrimin and Tinactin sprays with lot numbers starting with TN, CV, or NAA that were distributed to consumer venues between September 2018 and September 2021. The over-the-counter products are Lotrimin Anti-Fungal Athlete’s Foot Powder Spray, Lotrimin Anti-Fungal Jock Itch (AFJI) Athlete’s Foot Powder Spray, Lotrimin Anti-Fungal (AF) Athlete’s Foot Deodorant Powder Spray, Lotrimin AF Athlete’s Foot Liquid Spray, Lotrimin AF Athlete’s Foot Daily Prevention Deodorant Powder Spray, Tinactin Jock Itch (JI) Powder Spray, Tinactin Athlete’s Foot Deodorant Powder Spray, Tinactin Athlete’s Foot Powder Spray, and Tinactin Athlete’s Foot Liquid Spray.

Bayer has received no reports of adverse events related to the recall. The company also reported no concerns with its antifungal creams or other products.



In addition, Coppertone has issued a voluntary recall of specific lots of five spray sunscreen products because of the presence of benzene, according to a Sept. 30th company announcement, also posted on the FDA website. The recall includes Pure&Simple spray for babies, children, and adults; Coppertone Sport Mineral Spray; and Travel-sized Coppertone Sport spray. The specific lots were manufactured between January and June 2021, and are listed on the company announcement.

“Daily exposure to benzene at the levels detected in these affected Coppertone aerosol sunscreen spray products would not be expected to cause adverse health consequences based on generally accepted exposure modeling by numerous regulatory agencies,” according to the announcement. Coppertone has received no reports of adverse events related to the recall.

In the announcement, Coppertone advised consumers to discontinue use of the impacted products, dispose of the aerosol cans properly, and contact their physician or health care provider if they experience any problems related to the sunscreen sprays.

In May 2021, online pharmacy Valisure, which routinely tests their medications, petitioned the FDA to recall specific sunscreens after detecting high benzene levels in several brands and batches of sunscreen products. The FDA evaluated the petition, but the agency itself did not issue any recalls of sunscreens.

Clinicians are advised to report any adverse events to the FDA’s MedWatch Adverse Event Reporting program either online or by regular mail or fax using this form.

FDA clears first mobile rapid test for concussion

Article Type
Changed
Mon, 11/01/2021 - 14:48

The U.S. Food and Drug Administration has cleared SyncThink’s Eye-Sync technology to aid in the diagnosis of mild traumatic brain injury, the company has announced.

Eye-Sync is a virtual reality eye-tracking platform that provides objective measurements to aid in the assessment of concussion. It’s the first mobile, rapid test for concussion that has been cleared by the FDA, the company said.

As reported by this news organization, Eye-Sync received breakthrough designation from the FDA for this indication in March 2019.

The FDA initially cleared the Eye-Sync platform for recording, viewing, and analyzing eye movements to help clinicians identify visual tracking impairment.

The Eye-Sync technology uses a series of 60-second eye tracking assessments, neurocognitive batteries, symptom inventories, and standardized patient inventories to identify the type and severity of impairment after concussion.

“The platform generates customizable and interpretive reports that support clinical decision making and offers visual and vestibular therapies to remedy deficits and monitor improvement over time,” the company said.

In support of the application for use in concussion, SyncThink enrolled 1,655 children and adults into a clinical study that collected comprehensive patient and concussion-related data for over 12 months.

The company used these data to develop proprietary algorithms and deep learning models to identify a positive or negative indication of concussion.

The study showed that Eye-Sinc had sensitivity greater than 82% and specificity greater than 93%, “thereby providing clinicians with significant and actionable data when evaluating individuals with concussion,” the company said in a news release.

“The outcome of this study very clearly shows the effectiveness of our technology at detecting concussion and definitively demonstrates the clinical utility of Eye-Sinc,” SyncThink Chief Clinical Officer Scott Anderson said in the release.

“It also shows that the future of concussion diagnosis is no longer purely symptom-based but that of a technology driven multi-modal approach,” Mr. Anderson said.

Medtronic expands recall of MiniMed 600 insulin pumps

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

Medtronic has updated a previous recall of its MiniMed 600 series insulin pumps to include all with a potentially problematic clear retainer ring, not just those that appear damaged.

The U.S. Food and Drug Administration announced on Oct. 5 that Medtronic will now replace any MiniMed 600 series pump that has a clear retainer ring with an updated pump that includes a black retainer ring at no extra charge, regardless of warranty status.

In November 2019, Medtronic first advised patients to examine their pumps for potential damage to the ring, and to contact the company if it appeared to be loose, damaged, or missing. In February 2020, the FDA designated the recall as class 1, “the most serious type of recall,” for which use of the devices “may cause serious injuries or death.”

In this case, one potential risk is hyperglycemia. This can occur if the reservoir isn’t properly locked into place by the retainer ring, and insulin isn’t infused into the body. That, in turn, can lead to diabetic ketoacidosis. Another risk is hypoglycemia, which could result from over-delivery of insulin if the retainer ring breaks or detaches and the user inserts the reservoir back into the pump with the infusion set still connected to the body.

While serious injuries and deaths have been reported with the use of Minimed series 600 insulin pumps, “those adverse events may not have been directly related to the damaged clear retainer rings that are the basis for this recall,” according to the FDA notice. Nonetheless, lawsuits have reportedly been filed.

The new update is not a result of any new issues, Medtronic spokesperson Pamela Reese told this news organization. “Medtronic will proactively replace all MiniMed 600 series insulin pumps with the clear retainer ring design with an equivalent pump that has an updated black retainer ring design, which is designed to better withstand damage sustained by an accidental drop or bump on a hard surface.”

She added, “As we analyze the information that we continuously collect on the safety and performance of our insulin pumps, we recognize that patients who are still using the clear retainer ring could potentially encounter future problems. Therefore, we are currently accelerating our replacement as inventory allows over the coming months to eliminate any potential performance concerns and optimize patient safety and experience.”

The company has replaced nearly half of the clear retainer ring pumps that were in use since November 2019, she said.

The specific insulin pump products are the model 630G, distributed between September 2016 and February 2020; and the 670G, distributed between May 2015 and December 2020. The 630G is approved for people aged 16 years and older, and the 670G – which works with a continuous glucose monitor in a “hybrid closed-loop system – is available for people with type 1 diabetes as young as 7 years of age.

Johnson & Johnson requests FDA approval for vaccine booster doses

Article Type
Changed
Tue, 10/05/2021 - 13:36

Johnson & Johnson asked the Food and Drug Administration (FDA) on Tuesday to authorize an extra dose of its COVID-19 vaccine as a booster shot.

The company said it filed a request for people ages 18 and older who have received the one-shot vaccine. Johnson & Johnson submitted data for several different booster intervals -- ranging from 2 months to 6 months -- but didn’t formally recommend one to the FDA, The Associated Press reported.

“We’re describing the data to them,” Mathai Mammen, MD, head of global research and development for Janssen, the company’s vaccine division, told CNN.

“The process is not that we asked for a very specific interval -- we’re providing them data and we’re going to be presenting to the committee,” he said. “They’ll take all that into consideration when they ultimately decide on an appropriate interval.”

The FDA’s independent vaccine advisory committee meets next week to review data on booster shots from both Johnson & Johnson and Moderna. It’s the first step in the review process, which then requires approval from leaders at the FDA and Centers for Disease Control and Prevention. If both agencies authorize the extra shots, Americans could receive boosters from Johnson & Johnson and Moderna later this month, the AP reported.

Johnson & Johnson previously released data that showed the vaccine remains highly effective against COVID-19 at least 5 months after vaccination, with 81% efficacy against hospitalizations in the United States.

Two weeks ago, the company reported that a booster dose at 2 months or 6 months further lifted immunity, with a booster at 2 months providing 94% protection against moderate and severe COVID-19. The company said the 6-month booster raised antibodies by 12 times but didn’t release additional data at that time.

In September, the FDA authorized booster shots of the Pfizer vaccine for ages 65 and older, those who live in long-term care facilities, and those with higher risks for contracting COVID-19. The Biden administration is supporting a booster campaign to address potential waning vaccine immunity and remaining surges of the more contagious Delta variant, the AP reported.

COVID vaccination rates among pregnant people remain low

Article Type
Changed
Thu, 09/30/2021 - 09:34

COVID vaccination rates among pregnant people remain low, despite data that shows the vaccines can prevent the high risk of severe disease during pregnancy.

About 30% of pregnant people are vaccinated, according to the latest CDC data, with only 18% obtaining a dose during pregnancy. Health officials have been tracking the timing of vaccination before and during pregnancy.

The vaccination rates are even lower among pregnant Black people, CDC data shows. About 15% are fully vaccinated, compared with 25% of pregnant Hispanic and Latino people, 34% of pregnant White people, and 46% of pregnant Asian people.

“This puts them at severe risk of severe disease from COVID-19,” Rochelle Walensky, MD, the CDC director, said during a news briefing with the White House COVID-19 Response Team.

“We know that pregnant women are at increased risk of severe disease, of hospitalization and ventilation,” she said. “They’re also at increased risk for adverse events to their baby.”

Those who give birth while infected with COVID-19 had “significantly higher rates” of intensive care unit admission, intubation, ventilation, and death, according to a recent study published in JAMA Network Open.

Dr. Walensky said on Sept. 28 that studies show COVID-19 vaccines can be taken at any time while pregnant or breastfeeding. She noted that the vaccines are safe for both mothers and their babies.

“We’ve actually seen that some antibody from the vaccine traverses [the placenta] to the baby and, in fact, could potentially protect the baby,” she said.

Public health officials say the low vaccination rates can be attributed to caution around the time of pregnancy, concern for the baby, barriers to health care, and misinformation promoted online.

“Pregnancy is a precious time. It’s also a time that a lot of women have fear,” Pam Oliver, MD, an obstetrics and gynecology doctor and executive vice president of North Carolina’s Novant Health, told USA Today.

“It is natural to have questions,” she said. “So, let’s talk about what we know, let’s put it in perspective.”

Those who give birth while infected with COVID-19 had “significantly higher rates” of intensive care unit admission, intubation, ventilation, and death, according to a recent study published in JAMA Network Open.

Dr. Walensky said on Sept. 28 that studies show COVID-19 vaccines can be taken at any time while pregnant or breastfeeding. She noted that the vaccines are safe for both mothers and their babies.

“We’ve actually seen that some antibody from the vaccine traverses [the placenta] to the baby and, in fact, could potentially protect the baby,” she said.

Public health officials say the low vaccination rates can be attributed to caution around the time of pregnancy, concern for the baby, barriers to health care, and misinformation promoted online.

“Pregnancy is a precious time. It’s also a time that a lot of women have fear,” Pam Oliver, MD, an obstetrics and gynecology doctor and executive vice president of North Carolina’s Novant Health, told USA Today.

“It is natural to have questions,” she said. “So, let’s talk about what we know, let’s put it in perspective.”

COVID vaccination rates among pregnant people remain low, despite data that shows the vaccines can prevent the high risk of severe disease during pregnancy.

About 30% of pregnant people are vaccinated, according to the latest CDC data, with only 18% obtaining a dose during pregnancy. Health officials have been tracking the timing of vaccination before and during pregnancy.

The vaccination rates are even lower among pregnant Black people, CDC data shows. About 15% are fully vaccinated, compared with 25% of pregnant Hispanic and Latino people, 34% of pregnant White people, and 46% of pregnant Asian people.

“This puts them at severe risk of severe disease from COVID-19,” Rochelle Walensky, MD, the CDC director, said during a news briefing with the White House COVID-19 Response Team.

FDA approval for tisotumab vedotin in advanced cervical cancer

Article Type
Changed
Thu, 09/30/2021 - 15:20

The U.S. Food and Drug Administration has granted accelerated approval to tisotumab vedotin-tftv (Tivdak, Seagen/Genmab) for the treatment of adult patients with recurrent or metastatic cervical cancer who have experienced disease progression on or after chemotherapy.

There is currently no standard option for these patients. The mainstay of therapy in this setting is monotherapy with chemotherapy, but the benefit-risk profiles are poor, and overall response rates (ORRs) are less than 15%.

In the clinical trial that led to the accelerated approval, tisotumab vedotin-tftv yielded an ORR of 24%, which an expert not connected with the trial said was “impressive.”

“Tivdak’s approval as a monotherapy in the U.S. is an important milestone for women with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy, as they are in need of a new treatment option and we look forward to making it available to them,” Jan van de Winkel, PhD, chief executive officer of Genmab, said in a statement.

Tisotumab vedotin is an antibody–drug conjugate: A human monoclonal antibody directed against tissue factor, which is highly expressed on many solid tumors, is attached to the microtubule-disrupting agent monomethyl auristatin E.
 

Details of clinical trial data

The accelerated approval was based on the results of the innovaTV 204, an open-label, multicenter, single-arm clinical trial, which was published online on April 9 in The Lancet Oncology, as reported at the time.

The trial included 101 women with recurrent or metastatic squamous cell, adenocarcinoma, or adenosquamous cervical cancer whose disease had progressed with or after doublet chemotherapy with bevacizumab (if eligible by local standards) and who had received two or fewer previous systemic regimens for recurrent or metastatic disease.

All patients received tisotumab vendotin intravenously at a dose of 2.0 mg/kg (up to a maximum of 200 mg) once every 3 weeks until disease progression or unacceptable toxicity.

The confirmed ORR was 24% and included seven (7%) complete responses and 17 (17%) partial responses.

The disease control rate was 72%, and the median duration of response was 8.3 months. The median progression-free survival was 4.2 months; the 6-month progression-free survival rate was 30%.

Median overall survival (OS) was 12.1 months. OS rates were 79% at 6 months and 51% at 12 months.

Overall, the safety profile with tisotumab vedotin was manageable, the trialists reported. The most common treatment-related adverse events were alopecia (38%), epistaxis (30%), nausea (27%), conjunctivitis (26%), fatigue (26%), and dry eye (23%). Adverse events of grade 3 or higher were reported by 28% of patients and included neutropenia (3%), fatigue (2%), ulcerative keratitis (2%), and peripheral neuropathies (2%). One patient died as a result of septic shock that was considered by the investigators to be related to therapy.

The new product labeling includes a boxed warning for ocular toxicity. It notes that tisotumab vedotin “caused changes in the corneal epithelium and conjunctiva resulting in changes in vision, including severe vision loss, and corneal ulceration.” It recommends that clinicians conduct an ophthalmic exam at baseline, prior to each dose, and as clinically indicated and that patients adhere to premedication and required eye care before, during, and after infusion.
 

Confirmatory trial underway

Continued approval may be contingent upon verification and description of clinical benefit in confirmatory trials.

The confirmatory trial for tisotumab vedotin is already underway: The global phase 3 innovaTV 301 trial began in January 2021. It will compare tisotumab vendotin to chemotherapy (topotecan, vinorelbine, gemcitabine, irinotecan, or pemetrexed) for patients with recurrent or metastatic cervical cancer who have received one or two prior lines of systemic therapy.

FDA okays new oral CGRP antagonist for migraine prevention

Article Type
Changed
Thu, 12/15/2022 - 14:36

The Food and Drug Administration has approved atogepant (Qulipta), a novel calcitonin gene-related peptide (CGRP) receptor antagonist, for the prevention of episodic migraine, the manufacturer announced in a release.

The once-daily medication will be available in doses of 10 mg, 30 mg, and 60 mg.

“Qulipta provides a simple oral treatment option specifically developed to prevent migraine attacks and target CGRP, which is believed to be crucially involved in migraine in many patients,” coinvestigator Peter J. Goadsby, MD, PhD, DSc, neurologist and professor at the University of California, Los Angeles, and King’s College London, said in the release.

Approval was based partly on the findings from the phase 3 ADVANCE trial, in which patients with episodic migraine were randomly assigned to receive placebo or a 10-mg, 30-mg, or 60-mg daily dose of atogepant for 12 weeks.

As reported by this news organization, all three doses of atogepant reduced the number of mean monthly migraine days.

With this approval, neurologists will be able to choose from four monoclonal antibodies and two gepants for the preventive treatment of migraine.

“Having another gepant that can also be given preventively is a good idea, because one may be better than the other for a patient,” Alan M. Rapoport, MD, past president of the International Headache Society and founder and director emeritus of the New England Center for Headache, Stamford, Conn., told this news organization.

“Once we have a year or so of experience with atogepant, we’ll have a pretty good idea of which one works better preventively,” said Dr. Rapoport, who was not involved with the research.
 

Practice changing?

In the ADVANCE trial, there was a reduction of 3.69 migraine days with the 10-mg dose, 3.86 days with the 30-mg dose, and 4.2 days with the 60-mg dose. Placebo was associated with a reduction of 2.48 migraine days.

In addition, more than half of patients in each atogepant arm achieved a reduction in mean monthly migraine days of 50% or greater. This outcome occurred in 55.6% of the 10-mg atogepant group, 58.7% of the 30-mg group, and 60.8% of the 60-mg group. Approximately 29% patients who received placebo achieved this outcome.

The data indicated that atogepant has a favorable safety profile. The most common adverse events associated with treatment were constipation, nausea, and upper respiratory tract infection.

Dr. Rapoport, who is also a clinical professor of neurology at UCLA, noted that he was impressed with the efficacy.

“I’m not as impressed with the adverse events, but they’re not serious, and they don’t necessarily last,” he said.

Although being able to prescribe a single drug for acute and preventive treatment may be an advantage, it remains to be seen whether the tolerability and price of atogepant will be barriers for patients, Dr. Rapoport added.

How the approval will affect clinical practice is also unclear, he noted.

“If you’re going to start someone on a preventive, especially if it’s a woman of childbearing potential, you might just consider one of the two gepants. Doctors will decide once they see how they work,” said Dr. Rapoport.
 

 

 

Not a ‘breakthrough’ treatment

Also commenting ahead of the approval, Elizabeth W. Loder, MD, vice chair for academic affairs in the department of neurology at Brigham and Women’s Hospital, Boston, noted that the “safety of these CGRP medications in pregnancy is uncertain, and there are theoretical reasons to be concerned about it.”

Unlike injectable CGRP medications, atogepant is eliminated from the body relatively quickly after the patient stops taking it, said Dr. Loder, who is also professor of neurology at Harvard Medical School, Boston. However, atogepant may not otherwise differ greatly from other medications of its type.

“I don’t see a reason to think that one of these oral CGRP medicines is much more effective than another one,” said Dr. Loder.

“In my mind, as a clinician who will be prescribing these for patients, it will be cost and the ease of getting it covered that makes the difference,” she added.

These questions may raise concerns. “Those of us who treat patients who do not have private insurance find it very difficult to get these medications for them, even in situations where they have exhausted other alternatives,” said Dr. Loder.

Patients insured by Medicare or Medicaid “usually have no avenue to get some of these new, expensive treatments,” she said.

The approval of atogepant for acute and preventive treatment shows that the distinction between these indications may be artificial, Dr. Loder noted. The approval “will, I hope, help people think more flexibly about the way in which we use medications.”

It is a positive that atogepant has emerged as another option for preventive therapy, but the treatment cannot be considered a breakthrough, Dr. Loder added. The efficacy of atogepant, like that of other preventive treatments for migraine, is modest.

“It would be so nice if we could find things that were more effective than the treatments we currently have,” said Dr. Loder.

FDA issues proposed order for over-the-counter sunscreens

Article Type
Changed
Fri, 09/24/2021 - 16:55

Federal efforts to improve the quality, safety, and efficacy of over-the-counter sunscreens took a step forward today with the release of two orders aimed at updating regulatory requirements for most sunscreen products in the United States.

Dr. Theresa Michele

“We see it as a key public health priority and our regulatory obligation to make sure that marketed sunscreen products offer protection from the sun’s effects and that they deliver on those promises to consumers,” Theresa Michele, MD, director of the office of nonprescription drugs in the FDA’s Center for Drug Evaluation and Research, said during a media briefing.

When the Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed in 2020, the FDA was in the middle of amending a sunscreen monograph through the previous rule-making process, and the agency had issued a proposed rule for sunscreens in February of 2019. The CARES Act provided the FDA with new authority related to OTC drugs including sunscreens.

It also established a deemed final order for sunscreens, which set the current requirements for OTC sunscreen products marketed without an application. The deemed final order, released on Sept. 24, “essentially preserves the pre-CARES Act status quo marketing conditions for these sunscreens,” Dr. Michele explained. “Before the CARES Act was passed, sunscreens were marketed according to nearly identical terms that were described in an FDA enforcement discretion policy. For this reason, the agency believes that most sunscreens on the market today are already in compliance with this order.”

The CARES Act also required the FDA to issue a proposed order by Sept. 27 to amend and revise the deemed final order. Dr. Michele described the proposed order, which was released on Sept. 24, as “a vehicle to effectively transition our ongoing consideration of the appropriate requirements for OTC sunscreens marketed without approved applications from the previous rule-making process to this new order process. The provisions in today’s proposed order are therefore substantively the same as those described in the FDA’s 2019 proposed rule on sunscreens. With this proposed order, we’re proposing new requirements to improve the quality, safety, and efficacy of sunscreens that Americans use every day.”



The order proposes to update the generally recognized as safe (GRASE) status for the 16 active ingredients listed in the deemed final order. It also proposes that dosage forms that are GRASE for use as sunscreens include oils, lotions, creams, gels, butters, pastes, ointments, and sticks, and proposes GRASE status for spray sunscreens, subject to testing and labeling requirements.

Adam Friedman, MD, FAAD, professor and chair of dermatology at George Washington University, Washington, emphasized that photoprotection “is important for everyone, regardless of skin tone,” in an interview. “Broad-spectrum sunscreens with an SPF of 15 and higher play an important role in this. This should not be lost amidst the proposed order.”

Changes between the deemed and proposed order that he highlighted include a maximum SPF of 60+ (though up to 80 might be allowed) and that zinc oxide and titanium dioxide are GRASE. “The FDA did not say that nanoparticle formulations of these, which are easier to use, are not GRASE; they are asking for community input,” he said.

Other changes between the deemed and proposed order are that PABA and trolamine salicylate are not GRASE and that broad-spectrum testing will be mandatory. In addition, Dr. Friedman said, “sprays will be considered for GRASE so long as properly tested, labeling should be clearer (and a warning will be applied to those sunscreens not shown to prevent all the bad stuff with UVR [ultraviolet radiation]), and bug spray–sunscreen combos are a no-go.”

The FDA will consider comments on the proposed order submitted during a 45-day public comment period before issuing a revised final order. “As part of this process, we’ll consider all timely comments submitted both in response to the February 2019 proposed rule and to the current proposed order,” Dr. Michele said.

Dr. Friedman reported that he serves as a consultant and/or advisor to numerous pharmaceutical companies. He is also a speaker for Regeneron, Sanofi Genzyme, Abbvie, LRP, Janssen, Incyte, and Brickell Biotech, and has received grants from Pfizer, the Dermatology Foundation, Almirall, Incyte, Galderma, and Janssen.

Federal efforts to improve the quality, safety, and efficacy of over-the-counter sunscreens took a step forward today with the release of two orders aimed at updating regulatory requirements for most sunscreen products in the United States.

Dr. Theresa Michele

“We see it as a key public health priority and our regulatory obligation to make sure that marketed sunscreen products offer protection from the sun’s effects and that they deliver on those promises to consumers,” Theresa Michele, MD, director of the office of nonprescription drugs in the FDA’s Center for Drug Evaluation and Research, said during a media briefing.

When the Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed in 2020, the FDA was in the middle of amending a sunscreen monograph through the previous rule-making process, and the agency had issued a proposed rule for sunscreens in February of 2019. The CARES Act provided the FDA with new authority related to OTC drugs including sunscreens.

It also established a deemed final order for sunscreens, which set the current requirements for OTC sunscreen products marketed without an application. The deemed final order, released on Sept. 24, “essentially preserves the pre-CARES Act status quo marketing conditions for these sunscreens,” Dr. Michele explained. “Before the CARES Act was passed, sunscreens were marketed according to nearly identical terms that were described in an FDA enforcement discretion policy.

CDC chief overrules panel, OKs boosters for health care workers

Article Type

Fri, 09/24/2021 - 15:54

The director of the Centers for Disease Control and Prevention late Thursday overruled the recommendation of the agency’s advisory panel to broaden the number of Americans who are now eligible for a third dose of the Pfizer COVID-19 vaccine.

The CDC’s Advisory Committee on Immunization Practices earlier Thursday voted to allow several groups of Americans to get a booster shot, but voted not to recommend it for adults age 18 to 64 who live or work in a place where the risk of COVID-19 is high. That would have included health care workers and other frontline employees.

But CDC Director Rochelle Walensky, MD, decided to reverse that recommendation and include the 18-to-64-year-olds in her final decision.

“As CDC Director, it is my job to recognize where our actions can have the greatest impact,” Dr. Walensky said in a statement late Thursday night, according to published reports. “At CDC, we are tasked with analyzing complex, often imperfect data to make concrete recommendations that optimize health. In a pandemic, even with uncertainty, we must take actions that we anticipate will do the greatest good.”

Dr. Walensky agreed with the rest of the advisory committee's decisions, which included recommendations that the following groups also be eligible for a booster shot:

  • Adults ages 65 and up and residents of long-term care facilities
  • Adults ages 50 to 64 who have an underlying medical condition that may increase their risk from a COVID infection
  • Adults ages 18 to 49 who may be at increased risk from a COVID-19 infection because of an underlying medical condition, if a person feels like they need one based on a consideration of their individual benefit and risks.

About 26 million Americans are at least 6 months past the last dose of the Pfizer vaccines, making them eligible to receive a third dose.  About 13.6 million of them are over the age of 65.  Another 5.3 million are ages 50 to 64.

In making the recommendations, the committee left out healthcare workers. This was a departure from the Food and Drug Administration’s authorization which included boosters for those 65 and over, and for people 18 through 64 years of age who are at high risk for severe illness from the coronavirus, including essential workers – such as those in healthcare -- whose jobs increase their risk for infection.

This is the group Dr. Walensky added to the eligible list on her own.

Committee members “did not buy the need in occupational or institutional settings,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University in Nashville.  Dr. Schaffner sits on the ACIP workgroup that considered the evidence behind boosters. He said that he would have voted yes to offer boosters to healthcare and other essential workers.

“There was a real split in the committee,” he said.

The vote on boosters for healthcare and other high-risk workers was rejected 9 to 6.

“I think that there is ample evidence that people such as healthcare workers do not have repeated exposure in the workplace,” said Beth Bell, MD, a clinical professor at the University of Washington. “They’re using PPE as they should and they’re following the other policies within the healthcare setting. There’s lots of evidence that suggest that health care workers who become infected become infected because of exposures in the community.”

She was not alone in feeling cautious.

“I think this is an extremely slippery slope,” said Sarah Long, MD, a pediatric infectious disease specialist at Drexel University in Philadelphia, before her vote to reject boosters for healthcare and other high-risk workers.

“We might as well just say, ‘Give it to everybody 18 and over.’ We have an extremely effective vaccine. It’s like saying it’s not working, and it is working.”

The committee saw data showing that all of the vaccines remain highly protective against hospitalization and death for all age groups, though protection against getting sick with COVID has waned slightly over time and with the dominance of the more contagious Delta variant. Those at highest risk for a severe breakthrough infection — those that cause hospitalization or death — are older adults.
 

 

 

How much will the U.S. benefit from boosters?

Some felt squeamish about broadly recommending boosters at all.

“We have too much hope on the line with these boosters,” said James Loehr, MD, who is a family physician in Ithaca, N.Y. Dr. Loehr said he felt the goal of giving boosters in the United States should be to decrease hospitalizations, and he felt they would, but that the impact would likely be smaller than appreciated.

Based on his calculations of the benefits of boosters for each age group, Dr. Loehr said if boosters were given to all 13 million seniors previously vaccinated with the Pfizer vaccine, we might prevent 200 hospitalizations a day, “which would be a lot,” he noted. But, he said, “considering that we have 10,000 hospitalizations a day now, it’s probably not that much.”

Others agreed.

“I really think this is a solution looking for a problem,” said Jason Goldman, MD, an associate professor at Florida Atlantic University who was representing the American College of Physicians. “You know, I don’t think it’s going to address the issue of the pandemic. I really think it’s just going to create more confusion on the provider from the position of implementation, and I really think it’s going really far afield of the data.”

ACIP Chair Grace Lee, MD, a pediatric infectious disease specialist at Stanford, said she had cared for children who had died of COVID.

“I can tell you that their family members really wished they had extra protection for their kids, because they weren’t symptomatic. Nobody else was sick at home,” she said.

Dr. Lee said for her, access was paramount, and she was in favor of expanding access to boosters for as many people as possible.
 

Next steps

People who were initially vaccinated with either Moderna or Johnson & Johnson vaccines are excluded from booster recommendations, something many on the committee were uncomfortable with.

The FDA is still considering Moderna’s application to market booster doses. Johnson & Johnson hasn’t yet applied to the FDA for permission to offer second doses in the United States.

While the ACIP’s recommendations are important, in this case, they may not have a huge practical effect, said Schaffner. The CDC has already approved third shots for people who are immunocompromised, and no proof of a medical condition is required to get one.

More than 2 million people have already gotten a third dose, he noted, and not all of them are immunocompromised.

“They have heard the president say that, you know, everybody should get a booster, and they’ve taken that at face value,” he said.

FDA OKs Pfizer COVID booster for 65 and over, those at high risk

Article Type
Changed
Thu, 09/23/2021 - 10:31

 

The U.S. Food and Drug Administration (FDA) late Sept. 22 granted emergency use authorization (EUA) for a third dose of the Pfizer COVID-19 vaccine for those over the age of 65 and a wide swath of Americans at higher risk for infection.

The agency’s move comes as a Centers for Disease Control and Prevention (CDC) panel ended the first day of a 2-day meeting. That panel, the Advisory Committee on Immunization Practices (ACIP), is expected to vote Sept. 23 to instruct doctors on how to administer the boosters.

The FDA officially authorized the vaccine not only for individuals 65 and older, but also for people 18 through 64 years of age who are at high risk for severe illness from the coronavirus, including essential workers whose jobs increase their risk for infection.

“After considering the totality of the available scientific evidence and the deliberations of our advisory committee of independent, external experts, the FDA amended the EUA for the Pfizer-BioNTech COVID-19 vaccine to allow for a booster dose in certain populations such as health care workers, teachers and daycare staff, grocery workers and those in homeless shelters or prisons, among others,” Acting FDA Commissioner Janet Woodcock, MD, said in a news release.

The recommendations align with those from an FDA advisory panel Sept. 17.

The agency determined that the benefits of a booster dose outweigh the risks for people now authorized to receive it, according to the news release.
 

Other questions remain

So, how will this work? That was the main question weighing on the minds of the CDC’s ACIP during their first day of a 2-day meeting where they are expected to make recommendations on booster doses for Americans.

The panel discussed situations the FDA will still need to consider, such as what should be done for Americans who were originally vaccinated with a Moderna or Johnson and Johnson vaccine, but are not covered under the revised EUA, which is only for those people who received Pfizer’s two-dose vaccine regimen.

“That’s going to leave half of the people immunized in this age group having received the vaccine and being told that they’re at risk now for waning immunity and hospitalization unable to get a booster dose,” said committee member Sarah S. Long, MD, a professor of pediatrics at Drexel University College of Medicine in Philadelphia. “So that’s a big public health panic that we would like to avoid.”

Johnson and Johnson recently reported that second doses of its vaccine boosted its efficacy to almost 94% against COVID-19. A new study, published ahead of peer review, suggests that the efficacy of the single-dose Johnson and Johnson shot has fallen to about 78% against symptomatic infection during the Delta surge.

Moderna has applied for permission to market third doses of its vaccine in the United States, but the FDA has given no timeline on when it might make a decision. 

Doran Fink, MD, PhD, deputy director of the FDA’s Division of Vaccines and Related Products Applications, a representative advising the committee Sept. 22, said the agency was working as rapidly as possible on Moderna’s submission.

Regarding the question of whether it was OK to mix vaccines, rather than match them, Dr. Fink said there are currently not enough data available to inform that decision.

Those answers are coming, though. John Beigel, MD, associate director of clinical research at the National Institute of Allergy and Infectious Diseases, revealed that the federal government has a study underway to see what happens when the vaccines are mixed with each other. 

He said that data from the study would be available later this fall, and would certainly help physicians and other healthcare providers know whether it’s effective or safe to use them interchangeably.
 

 

 

Correlates of immunity

The ACIP left much of its schedule open Sept. 23 to discuss extra Pfizer doses and vote on how they should be used.

Pfizer had originally applied to the FDA for an amendment to its FDA approval, which would have given doctors a freer hand to prescribe third doses as they saw fit, in patients as young as 16.

But the FDA’s Vaccines and Related Biological Products Advisory Committee voted Sept. 17 against granting the amendment. The committee was particularly concerned about the lack of data in teens ages 16 and 17, who have the highest risk for a rare side effect that causes heart inflammation that requires hospital care.

Instead, they recommended — and the FDA agreed per their decision Sept. 22 — that third doses should be given to people at higher risk for severe breakthrough infections because of advanced age or because they work in an occupation that puts them at high risk for exposure. 

The CDC panel heard important presentations on new science that is helping to identify the correlates of immunity. 

The correlates of immunity are biomarkers that can be measured in blood that help doctors understand how protected a person may be against COVID-19. These markers of immunity are not yet known for the COVID-19 vaccines.

Emerging evidence shows that booster doses of the Pfizer vaccine cause front-line immune defenders — called binding antibodies — to roughly triple soon after a person gets the third shot. 

Neutralizing antibodies also jump soon after two vaccine doses, but they fall over time, which is natural. The body doesn’t need these foot soldiers to be on guard all the time, so they go away. 

The body retains its memory of how to make them, however, so they can quickly be marshaled again, if needed.

Early studies suggest that antibodies account for about two thirds of a person’s protection against COVID, while the longer-lasting T-cells and B-cells account for about one third.

After the antibody levels fall, it may take a few days to recreate this army. In the meantime, the virus can try to break in. This can cause symptoms, which can make a person feel terrible, but for the most part, vaccinated individuals don’t need hospital care and are nearly always protected from dying — even against the Delta variant.

Those most likely to be at risk for a breakthrough infection are older, because immune function wanes with age.
 

Essential workers

Essential workers, such as those who work in healthcare, may also benefit from high antibody levels, which can minimize symptoms and help them get back to work more quickly.

Helen Talbot, MD, MPH, an associate professor of medicine at Vanderbilt University Medical Center in Nashville, said that in her area staffing levels are critical right now.

“I’m actually sitting in one of the deepest red [states] with high rates of COVID. We don’t have enough health care workers currently to take care of the unvaccinated,” she said. 

“When we have beds, we are often missing staff, and so the idea of vaccinating health care workers is to be a little bit different than our idea of using vaccines in the general population,” Dr. Talbot said.

Oliver Brooks, MD, chief medical officer of the Watts Healthcare Corporation in Los Angeles, said he was in favor of making a public statement about the temporary nature of the potential recommendations Sept. 23, because they probably won’t cover all who might need a third shot.

“We may want to go on record stating what it is that would allow us to broaden our recommendation or restrict our recommendation,” Dr. Brooks said.

The considerations of who should get an extra dose are not always straightforward.

New modeling by the Harvard TH Chan School of Public Health and the CDC to assist the government’s decisions on boosters had a surprise finding: in nursing homes, it’s more effective to vaccinate healthcare workers than it is to give booster doses to these residents. Nursing homes are at the mercy of community transmission. 

In regions with high transmission, it’s easy for a caregiver to bring the virus into a facility — so the models found that the transmission from these workers is a more effective strategy than giving third doses to the already highly vaccinated group of seniors who live in them.

The U.S. Food and Drug Administration (FDA) late Sept. 22 granted emergency use authorization (EUA) for a third dose of the Pfizer COVID-19 vaccine for those over the age of 65 and a wide swath of Americans at higher risk for infection.

The agency’s move comes as a Centers for Disease Control and Prevention (CDC) panel ended the first day of a 2-day meeting. That panel, the Advisory Committee on Immunization Practices (ACIP), is expected to vote Sept. 23 to instruct doctors on how to administer the boosters.

The FDA officially authorized the vaccine not only for individuals 65 and older, but also for people 18 through 64 years of age who are at high risk for severe illness from the coronavirus, including essential workers whose jobs increase their risk for infection.

“After considering the totality of the available scientific evidence and the deliberations of our advisory committee of independent, external experts, the FDA amended the EUA for the Pfizer-BioNTech COVID-19 vaccine to allow for a booster dose in certain populations such as health care workers, teachers and daycare staff, grocery workers and those in homeless shelters or prisons, among others,” Acting FDA Commissioner Janet Woodcock, MD, said in a news release.

The recommendations align with those from an FDA advisory panel Sept. 17.

The agency determined that the benefits of a booster dose outweigh the risks for people now authorized to receive it, according to the news release.
 

Other questions remain

So, how will this work? That was the main question weighing on the minds of the CDC’s ACIP during their first day of a 2-day meeting where they are expected to make recommendations on booster doses for Americans.

The panel discussed situations the FDA will still need to consider, such as what should be done for Americans who were originally vaccinated with a Moderna or Johnson and Johnson vaccine, but are not covered under the revised EUA, which is only for those people who received Pfizer’s two-dose vaccine regimen.

“That’s going to leave half of the people immunized in this age group having received the vaccine and being told that they’re at risk now for waning immunity and hospitalization unable to get a booster dose,” said committee member Sarah S. Long, MD, a professor of pediatrics at Drexel University College of Medicine in Philadelphia. “So that’s a big public health panic that we would like to avoid.”
