HEALTH CARE BRIEFING: FDA Vaccine Rules Challenged as Weak

Brandon Lee and Alex Ruoff, Bloomberg Government: October 23, 2020


U.S. vaccine advisers questioned whether safety and efficacy standards set by Food and Drug Administration officials were high enough to warrant emergency authorization of a shot.

About two dozen outside advisers to the FDA with expertise in infectious diseases met yesterday to weigh in on agency standards that require a vaccine to work in at least 50% of people and for drugmakers to collect two months of safety data on at least half of clinical trial volunteers.

“They haven’t gone far enough” in terms of safety, said Hayley Altman-Gans, a panel member and pediatrics professor at Stanford University Medical Center.

Many panel members and outside researchers who commented during the hearing worried that if a vaccine is rushed out that later turns out to have safety problems or to be less effective than promised, it could backfire in a big way, undermining public confidence in Covid-19 vaccines for years to come.

Several panel members expressed concern that the two-month safety follow-up the FDA is calling for before a vaccine gets an emergency authorization is simply not enough. In addition to safety, it means that doctors won’t know whether a vaccine’s efficacy could fade after just a few months.

Diana Zuckerman of the National Center for Health Research told the committee the vaccine trials “have serious design flaws.”

The trials are too geared to preventing mild infections, and may not show whether they prevent severe infections and hospitalizations, she said. Longer follow up may be especially important because some of the first vaccines, including messenger RNA vaccines from Pfizer and Moderna, are based on new technologies that have never been used in an approved product.

FDA Vaccine Rules Challenged as Weak at Advisory Panel Meeting

Anna Edney and Robert Langreth, Bloomberg Business: October 22, 2020


About two dozen outside advisers to the FDA with expertise in infectious diseases met Thursday to weigh in on agency standards that require a vaccine to work in at least 50% of people and for drugmakers to collect two months of safety data on at least half of clinical trial volunteers.

“They haven’t gone far enough” in terms of safety, said Hayley Altman-Gans, a panel member and pediatrics professor at Stanford University Medical Center.

Many panel members and outside researchers who commented during the hearing worried that if a vaccine is rushed out that later turns out to have safety problems or to be less effective than promised, it could backfire in a big way, undermining public confidence in Covid-19 vaccines for years to come.

Archana Chatterjee, advisory panel member and dean of Chicago Medical School, said the public has a lot of concern about safety. Meanwhile, she added, “What we’re being asked to do is to build this plane as we fly it.”

Several panel members expressed concern that the two-month safety follow-up the FDA is calling for before a vaccine gets an emergency authorization is simply not enough. In addition to safety, it means that doctors won’t know whether a vaccine’s efficacy could fade after just a few months.

Panel member Amanda Cohn, who is chief medical officer at the National Center for Immunization and Respiratory Diseases, worried that the efficacy of vaccines that just meet the 50% threshold after two months may see reduced effectiveness a few months later if the shot doesn’t offer a long period of protection.

“Very rarely do we look at [vaccine efficacy] so shortly after completing a series,” according to Cohn, whose organization is part of the Centers for Disease Control and Prevention.

Design Flaws

The advisers weren’t alone in questioning the standards. Diana Zuckerman of the National Center for Health Research told the committee the vaccine trials “have serious design flaws.”

The two-month follow up the FDA has asked for is too short to establish how long a vaccine will work, and the trials are too geared to preventing mild infections, and may not show whether they prevent severe infections and hospitalizations, she said.

Longer follow-up may be especially important because some of the first vaccines, including messenger RNA vaccines from Pfizer Inc. and Moderna Inc., are based on new technologies that have never been used in an approved product.

The debate over the rigor of the FDA guidelines was one of two main issues debated before the committee, which heard comments from regulators, drugmakers and the public. The second questioned whether trial participants on a placebo should be advised when a vaccine is deemed to be safe and effective.

FDA Updates Breast Implant Labeling Recommendations to Help Inform Patients About Dangerous Potential Side Effects

Beth Fand Incollingo, Cure: September 29, 2020


Makers of breast implants should supplement their labeling to include a boxed warning about health problems that can arise from the devices, along with a patient decision checklist that highlights those concerns, according to final guidance issued today by the Food and Drug Administration.

The guidance, titled “Breast Implants – Certain Labeling Recommendations to Improve Patient Communication,” recommends, but does not mandate, that manufacturers include information about two major health issues that can arise from implant use: breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) and breast implant illness (BII), an autoimmune condition that can result in brain fog, fatigue, rash, and muscle or joint pain. A draft of the document was issued in 2019.

[…]

Roxane Vermeland, a breast cancer survivor who was treated for BIA-ALCL after receiving implants as part of breast reconstruction after mastectomy, was pleased to hear about the FDA’s decision.

“This is great news,” she said in a statement to CURE®. “We have been advocating hard for this, as women need to know the risks of implants up front so they can make an informed decision. The black-box warning alone is a major accomplishment for us which will truly make women think about the decision to put implants into their bodies. I am in tears as I write this.”

Guidance details

According to the guidance, the boxed warning should state that breast implants are not considered lifetime devices; the chance of developing complications increases over time; some complications will require more surgery; implants, particularly textured ones, have been associated with the development of BIA-ALCL; and implants have been associated with systemic symptoms. The checklist should note situations in which the device should not be used; considerations for a successful breast implant candidate; risks associated with surgery and BIA-ALCL; the importance of appropriate physician education, training and experience; the risk of BII; and should suggest discussion of options other than breast implants, the guidance states.

The guidance also suggests updates to the silicone gel-filled breast implant rupture screening recommendations, stating when MRIs should be conducted; inclusion of an easy-to-find description of the materials used to make the implants; and provision of patient device cards that will inform patients about what kind of implants they have, state a serial or lot number for the specific devices and include a toll-free phone number for the manufacturer.

The labeling recommendations are intended to enhance, but not replace, discussions between doctors and patients about the benefits and risks of breast implants, the FDA wrote in a press release.

Finally, the FDA has updated its guidance titled “Saline, Silicone Gel, and Alternative Breast Implants” to make it consistent with the new labeling recommendations. The FDA stated that it will continue to work with professional medical societies, patient advocacy groups and women’s health organizations to help ensure that risk information about breast implants is disseminated to patients.

“As new information has become available about the risks and complications of breast implants, it is critical that women have access to information they need to make informed decisions,” Dr. Binita Ashar, director of the Office of Surgical and Infection Control Devices in the Center for Devices and Radiological Health, said in the release. “After working with stakeholders, including patients, today we are recommending format and content changes to breast implant labeling so the information is presented in an easy-to-understand way. It is important that patients discuss the risks and benefits of breast implants with their health care provider, and we hope that these labeling recommendations will help in facilitating these discussions.”

[…]

Diana Zuckerman, president of the National Center for Health Research and its Cancer Prevention and Treatment Fund, also had a concern, pointing out that guidance from the FDA usually consists of recommendations that are not enforceable.

“That’s a big question for us,” she said in an interview with CURE®. “Because we know from experience that, if it’s a suggestion, there are just a lot of doctors who aren’t going to follow through. We think this needs to be required, and we will be working with the plastic surgeons’ medical societies to try to ensure that they urge their members in the strongest possible terms to use this checklist, either the FDA’s version of it or our version, which we think is better.”

An ongoing issue

The FDA also acted on testimony given at the March panel when it requested in July that Allergan, which was since purchased by AbbVie, issue a worldwide recall of any of its Natrelle Biocell textured implants and tissue expanders that remained on shelves. That’s because textured implants, particularly the Natrelle Biocell product line filled with either saline or silicone, have been linked with BIA-ALCL. As of Jan. 5, the cancer had been diagnosed in 733 patients and killed 36, the FDA reported Aug. 20.

“Although the overall incidence of BIA-ALCL appears to be relatively low, once the evidence indicated that a specific manufacturer’s product appeared to be directly linked to significant patient harm, including death, the FDA took action to alert the firm to new evidence indicating a recall is warranted to protect women’s health,” Dr. Amy Abernethy, the FDA’s principal deputy commissioner, said in July.

First identified about 20 years ago, BIA-ALCL is a rare type of non-Hodgkin lymphoma that arises specifically in women with implants. The FDA first warned women about BIA-ALCL in 2011.

Breast implant illness, meanwhile, seems to occur more often in women who have a personal or family history of autoimmune conditions, experts said, suggesting that more research is needed and that these women should be warned before getting implants. One expert at the 2019 hearing said that this group should opt against implants.

Jennifer Cook of Georgia, who received a diagnosis of BIA-ALCL in 2017, told the 2019 FDA panel that she received her implants as part of a clinical trial and signed a consent form stating that there was no established scientific evidence linking them with cancer. Over many years, she said, no one informed her that a risk had been established, and she found out only by watching a play on the topic at the middle school where she taught.

“I was shocked and thought I would need to reprimand the students for making false statements, and then I learned the horrifying truth,” Cook said. “Shortly thereafter, I recognized that I had symptoms. I was blindsided. I was deceived, and I don’t want anyone else to go through that.”
