FDA/CDC

The U.S. Food and Drug Administration approved finerenone (Kerendia), the first agent from a new class of nonsteroidal mineralocorticoid receptor antagonists (MRAs), on July 9 for treating patients with chronic kidney disease (CKD) associated with type 2 diabetes.

Janani Rangaswami, MD, a nephrologist not involved with finerenone’s development, hailed the action as a “welcome addition to therapies in the cardiorenal space.”

She also highlighted that until more evidence accumulates, finerenone will take a back seat to two more established renal-protective drug classes for patients with type 2 diabetes, the renin-angiotensin system inhibitors (RASIs), and the sodium-glucose cotransporter 2 (SGLT2) inhibitors.

RASIs, which include angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, remain first-line treatments for slowing the progression of CKD in patients with type 2 diabetes. The efficacy and safety of these agents are well-established. The trial that led to the FDA’s decision to approve finerenone, FIDELIO-DKD, compared it against placebo in more than 5,700 patients with type 2 diabetes who were all already taking a maximum-tolerated dose of an RASI.
 

Scant data on combining finerenone with an SGLT2 inhibitor

Two agents in the SGLT2 inhibitor class, approved initially for type 2 diabetes, received additional FDA approvals for slowing kidney disease: Canagliflozin (Invokana), which was approved in September 2019 on the basis of the CREDENCE trial, and dapagliflozin (Forxiga/Farxiga), which was approved in April 2021 on the basis of DAPA-CKD. Nephrologists now speak of this drug class as “practice changing.”

When FIDELIO-DKD enrolled patients from September 2015 to June 2018, it was still early days for use of SGLT2 inhibitors for patients with type 2 diabetes; hence, fewer than 5% of enrolled patients received an SGLT2 inhibitor, making it impossible to say how well finerenone works when taken along with one of these drugs.

“The big question that persists is the incremental benefit [from finerenone] on top of an SGLT2 inhibitor,” commented Dr. Rangaswami, director of the cardiorenal program at George Washington University, Washington, and chair-elect of the Council on the Kidney in Cardiovascular Disease of the American Heart Association.

“It is hard to extrapolate incremental benefit from existing finerenone trial data given the low background use of SGLT2 inhibitors [in FIDELIO-DKD],” she said in an interview.

George Bakris, MD, lead investigator for FIDELIO-DKD, agrees.
 

SGLT2 inhibitors are a ‘must’ for CKD

An SGLT2 inhibitor “must be used, period,” for patients with type 2 diabetes and CKD. “The evidence is very strong,” said Dr. Bakris, speaking in June 2021 during a session of the virtual annual Congress of the European Renal Association and European Dialysis and Transplant Association.

Because of inadequate evidence on how finerenone works when administered in addition to an SGLT2 inhibitor, for the time being, the combination must be considered investigational, he added.

Study results “need to show that combination therapy [with an SGLT2 inhibitor and finerenone] is better” than an SGLT2 inhibitor alone, said Dr. Bakris, professor of medicine and director of the Comprehensive Hypertension Center of the University of Chicago.

During his June talk, Dr. Bakris predicted that by 2023, enough data will exist from patients treated with both an SGLT2 inhibitor and finerenone to allow an evidence-based approach to combination treatment.

Finerenone’s approval makes it an immediate choice for patients with type 2 diabetes and CKD secondary to polycystic kidney disease, a group who are not candidates for an SGLT2 inhibitor, said Dr. Rangaswami.

But “if a patient is eligible for an SGLT2 inhibitor, I would not stop that in favor of starting finerenone” on the basis of current knowledge, she noted.
 

‘Not your mother’s spironolactone’

Although finerenone is classified an MRA, the class that also includes the steroidal agents spironolactone and eplerenone, the nonsteroidal structure of finerenone means “it has nothing to do with spironolactone. It’s a different molecule with different chemistry,” Dr. Bakris said in his June talk.

Although the risk for hyperkalemia has been a limiting factor and a deterrent to routine use of steroidal MRAs for preventing progression of CKD, hyperkalemia is much less of a problem with finerenone.

Main results from FIDELIO-DKD, published in late 2020, showed that the percentage of patients receiving finerenone who permanently stopped taking the drug because of hyperkalemia was 2.3%, higher than the 0.9% rate among patients in the trial who received placebo but about a third of the rate of patients treated with spironolactone in a historical cohort.

“You need to pay attention” to the potential development of hyperkalemia in patients taking finerenone, “but it is not a major issue,” Dr. Bakris said. “Finerenone is not your mother’s spironolactone,” he declared.

FIDELIO-DKD’s primary outcome, a combination of several adverse renal events, showed that treatment with finerenone cut this endpoint by a significant 18% compared with placebo. The study’s main secondary endpoint showed that finerenone cut the incidence of combined cardiovascular disease events by a significant 14% compared with placebo. Adverse events were similar in the finerenone and placebo arms.
 

Finerenone also shows promise for reducing CVD events

Bayer, the company that developed and will market finerenone, announced in May 2021 topline results from a companion trial, FIGARO-DKD. That trial also enrolled patients with type 2 diabetes and CKD, but a primary endpoint of that trial combined the rates of cardiovascular death and nonfatal cardiovascular disease events. The results from this trial showed a significant difference in favor of finerenone compared with placebo.

“Given the common pathways that progression of CKD and cardiovascular disease share with respect to [moderating] inflammation and [slowing development of] fibrosis, it is not surprising that a signal for benefit was seen at the different ends of the cardiorenal spectrum,” Dr. Rangaswami said.

FIDELIO-DKD and FIGARO-DKD were sponsored by Bayer, the company that markets finerenone (Kerendia). Dr. Bakris has been a consultant to and has received research funding from Bayer and from numerous other companies. Dr. Rangaswami has disclosed no relevant financial relationships.

The U.S. Food and Drug Administration has approved an updated label for the controversial Alzheimer’s drug aducanumab (Aduhelm), emphasizing that the drug should only be used in patients with the earliest stages of disease – the group studied in the clinical trials.

The FDA approved aducanumab in early June amid significant controversy and disregarding the recommendation by its own advisory panel not to approve the drug. The original prescribing information implied that the drug – which is administered intravenously and costs around $56,000 a year – could be used for treatment of any patient with Alzheimer’s disease.

The updated label now states that aducanumab should be initiated only in patients with mild cognitive impairment (MCI) or mild dementia stage of disease – the population in which treatment was initiated in the clinical trials leading to approval of the anti-amyloid drug.

The FDA granted accelerated approval of the drug based on data from clinical trials showing a reduction in amyloid beta plaques observed in patients with MCI or mild dementia stage of disease.

“Continued approval for the indication may be contingent upon verification of clinical benefit in confirmatory trial(s),” the label states. It emphasizes that there are no safety or effectiveness data on starting aducanumab treatment at earlier or later stages of the disease than were studied.

“Based on our ongoing conversations with prescribing physicians, FDA, and patient advocates, we submitted this label update with the goal to further clarify the patient population that was studied across the three Aduhelm clinical trials that supported approval,” Alfred Sandrock Jr., MD, PhD, Biogen’s head of research and development, said in a statement announcing the label update.   

“We are committed to continue to listen to the community’s needs as clinical practice adapts to this important, first-in-class treatment option,” said Dr. Sandrock.

The contagious Delta variant has become the dominant form of the coronavirus in the United States, now accounting for more than 51% of COVID-19 cases in the country, according to new CDC data to updated on July 6.

The variant, also known as B.1.617.2 and first detected in India, makes up more than 80% of new cases in some Midwestern states, including Iowa, Kansas, and Missouri. Delta also accounts for 74% of cases in Western states such as Colorado and Utah and 59% of cases in Southern states such as Louisiana and Texas.

Communities with low vaccination rates are bearing the brunt of new Delta cases. Public health experts are urging those who are unvaccinated to get a shot to protect themselves and their communities against future surges.

“Right now we have two Americas: the vaccinated and the unvaccinated,” Paul Offit, MD, an infectious disease specialist at Children’s Hospital of Philadelphia, told NPR.

“We’re feeling pretty good right now because it’s the summer,” he said. “But come winter, if we still have a significant percentage of the population that is unvaccinated, we’re going to see this virus surge again.”

So far, COVID-19 vaccines appear to protect people against the Delta variant. But health officials are watching other variants that could evade vaccine protection and lead to major outbreaks this year.

For instance, certain mutations in the Epsilon variant may allow it to evade the immunity from past infections and current COVID-19 vaccines, according to a new study published July 1 in the Science. The variant, also known as B.1.427/B.1.429 and first identified in California, has now been reported in 34 countries and could become widespread in the United States.

Researchers from the University of Washington and clinics in Switzerland tested the variant in blood samples from vaccinated people, as well as those who were previously infected with COVID-19. They found that the neutralizing power was reduced by about 2 to 3½ times.

The research team also visualized the variant and found that three mutations on Epsilon’s spike protein allow the virus to escape certain antibodies and lower the strength of vaccines.

Epsilon “relies on an indirect and unusual neutralization-escape strategy,” they wrote, saying that understanding these escape routes could help scientists track new variants, curb the pandemic, and create booster shots.

In Australia, for instance, public health officials have detected the Lambda variant, which could be more infectious than the Delta variant and resistant to vaccines, according to Sky News.

A hotel quarantine program in New South Wales identified the variant in someone who had returned from travel, the news outlet reported. Also known as C.37, Lambda was named a “variant of interest” by the World Health Organization in June.

Lambda was first identified in Peru in December and now accounts for more than 80% of the country’s cases, according to the Financial Times. It has since been found in 27 countries, including the U.S., U.K., and Germany.

The variant has seven mutations on the spike protein that allow the virus to infect human cells, the news outlet reported. One mutation is like another mutation on the Delta variant, which could make it more contagious.

In a preprint study published July 1, researchers at the University of Chile at Santiago found that Lambda is better able to escape antibodies created by the CoronaVac vaccine made by Sinovac in China. In the paper, which hasn’t yet been peer-reviewed, researchers tested blood samples from local health care workers in Santiago who had received two doses of the vaccine.

“Our data revealed that the spike protein ... carries mutations conferring increased infectivity and the ability to escape from neutralizing antibodies,” they wrote.

The research team urged countries to continue testing for contagious variants, even in areas with high vaccination rates, so scientists can identify mutations quickly and analyze whether new variants can escape vaccines.

“The world has to get its act together,” Saad Omer, PhD, director of the Yale Institute for Global Health, told NPR. “Otherwise yet another, potentially more dangerous, variant could emerge.”

Researchers from the University of Washington and clinics in Switzerland tested the variant in blood samples from vaccinated people, as well as those who were previously infected with COVID-19. They found that the neutralizing power was reduced by about 2 to 3½ times.

The research team also visualized the variant and found that three mutations on Epsilon’s spike protein allow the virus to escape certain antibodies and lower the strength of vaccines.

Epsilon “relies on an indirect and unusual neutralization-escape strategy,” they wrote, saying that understanding these escape routes could help scientists track new variants, curb the pandemic, and create booster shots.

In Australia, for instance, public health officials have detected the Lambda variant, which could be more infectious than the Delta variant and resistant to vaccines, according to Sky News.

A hotel quarantine program in New South Wales identified the variant in someone who had returned from travel, the news outlet reported. Also known as C.37, Lambda was named a “variant of interest” by the World Health Organization in June.

Lambda was first identified in Peru in December and now accounts for more than 80% of the country’s cases, according to the Financial Times. It has since been found in 27 countries, including the U.S., U.K., and Germany.

The variant has seven mutations on the spike protein that allow the virus to infect human cells, the news outlet reported. One mutation is like another mutation on the Delta variant, which could make it more contagious.

In a preprint study published July 1, researchers at the University of Chile at Santiago found that Lambda is better able to escape antibodies created by the CoronaVac vaccine made by Sinovac in China. In the paper, which hasn’t yet been peer-reviewed, researchers tested blood samples from local health care workers in Santiago who had received two doses of the vaccine.

“Our data revealed that the spike protein ... carries mutations conferring increased infectivity and the ability to escape from neutralizing antibodies,” they wrote.

The research team urged countries to continue testing for contagious variants, even in areas with high vaccination rates, so scientists can identify mutations quickly and analyze whether new variants can escape vaccines.

“The world has to get its act together,” Saad Omer, PhD, director of the Yale Institute for Global Health, told NPR. “Otherwise yet another, potentially more dangerous, variant could emerge.”

The U.S. Food and Drug Administration has approved 1-month – as short as 28 days – dual antiplatelet therapy (DAPT) labeling for Xience stents in patients at high risk for bleeding, Abbott announced on June 30.

Patients who receive stents are typically on DAPT regimens such as aspirin and P2Y12 inhibitors for 6 to 12 months to prevent blood clots, but high-bleeding risk patients can experience bleeding during prolonged DAPT.

“The new FDA approval for DAPT for the XIENCE family of stents provides interventional cardiologists confidence they are delivering the best care to patients with high bleeding risk. A short DAPT duration minimizes risks for high bleeding risk patients and allows them to return to daily life sooner and with more assurance,” Roxana Mehran, MD, Icahn School of Medicine at Mount Sinai, New York and the global principal investigator for Abbott’s Short DAPT program (XIENCE 28 and XIENCE 90), said in a news release.

The new labeling comes on the heels of European CE Mark approval for the Xience stents with DAPT as short as 28 days, “giving Xience stents the shortest DAPT indication in the world,” the company noted.

Results of the XIENCE 28 trial were used to support the new CE Mark DAPT indication. The trial showed no increase in death of myocardial infarction between 1 and 6 months and a significantly lower risk for severe bleeding with the Xience stent and 1-month DAPT, compared with 6-month DAPT in more than 1,600 high-bleeding risk patients.

The XIENCE 90 trial involving more than 2,000 high-bleeding risk patients reported no difference in death or MI between 3 and 12 months with Xience and 3-month DAPT versus 12-month DAPT.

Abbott scored a second win, also announcing FDA and CE Mark approval of its next-generation Xience Skypoint stent in high-bleeding risk patients with 1-month DAPT.

“XIENCE Skypoint is easier to place and allows physicians to treat larger blood vessels through improved stent expansion that can open clogged vessels more effectively,” the company said.

The U.S. Food and Drug Administration has declined to approve the anti-CD3 monoclonal antibody teplizumab (Tzield, Provention Bio) for the delay of type 1 diabetes in at-risk individuals, despite narrow endorsement in a 10-7 vote in favor of approval by one of its advisory panels in May.

According to the company, the FDA did not cite any clinical deficiencies related to the efficacy and safety data packages submitted as part of the biologics license application for teplizumab.

Rather, the sticking point appears to be a study in healthy volunteers that had been raised as an issue with Provention Bio in April.

That study was designed to compare the planned commercial product with the product originally manufactured for clinical trials, but the former was not pharmacologically comparable to the latter, the FDA said in its complete response letter, issued on July 2.

The company expects, later this quarter, to obtain data from a substudy in patients receiving 12 days of therapy in the ongoing PROTECT trial of newly diagnosed patients with type 1 diabetes, which it hopes will help alleviate the FDA’s concerns.

“Upon review of the results from this substudy, the company will determine whether to submit these data to the FDA for its review ... to support pharmacokinetic comparability or otherwise justify why pharmacokinetic comparability is not necessary,” it said in its statement.

The FDA’s complete response letter had also mentioned additional issues related to product quality that Provention believes it has or will be able to address in the short term.

Teplizumab delays type 1 diabetes onset by years

Phase 2 data showing that a 14-day teplizumab infusion delayed the onset of type 1 diabetes by 2 years in high-risk relatives of people with the condition were called “game-changing” when presented at the American Diabetes Association 2019 Scientific Sessions and simultaneously published in the New England Journal of Medicine. These were the data considered by the FDA advisory panel in May.

In response to the FDA decision, the type 1 diabetes research and advocacy organization JDRF said: “It is unfortunate that the FDA has not approved teplizumab at this time and instead has requested additional information from the sponsor. We look forward to Provention Bio addressing the issues outlined in the Complete Response Letter and working with the FDA to bring this option to market safely.”

Teplizumab is one of several potential disease-modifying therapies being studied for type 1 diabetes administered either soon after diagnosis or to asymptomatic individuals with high-risk autoantibodies.

“Disease-modifying therapies such as teplizumab will help address the unmet needs of people with type 1 diabetes and those at risk for developing the disease. In the meantime, our organization will continue to support the research of other disease-modifying therapies that put us on the critical pathway to preventing and ultimately curing type 1 diabetes,” JDRF said in a statement.

Breast and cervical cancer screenings declined sharply in the early months of the COVID-19 pandemic, particularly among certain racial and ethnic minority groups and rural populations, notes the U.S. Centers for Disease Control and Prevention.

The new data come from the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), a program that provides cancer screening services to women with low income and inadequate health insurance.

The data show that the total number of screenings funded by the NBCCEDP declined by 87% for breast cancer screening and by 84% for cervical cancer screening in April 2020 in comparison with the previous 5-year averages for that month.

The declines in breast cancer screening varied from 84% among Hispanic women to 98% among American Indian/Alaskan Native women. The declines in cervical cancer screening varied from 82% among Black women to 92% among Asian Pacific Islander women.

In April 2020, breast cancer screening declined by 86% in metro areas, 88% in urban areas, and 89% in rural areas in comparison with respective 5-year averages. For cervical cancer screenings, the corresponding declines were 85%, 77%, and 82%.

The findings are consistent with those from studies conducted in insured populations, note the authors, led by the Amy DeGroff, PhD, MPH, of the CDC’s National Center for Chronic Disease Prevention and Health Promotion.

“Prolonged delays in screening related to the COVID-19 pandemic may lead to delayed diagnoses, poor health consequences, and an increase in cancer disparities among women already experiencing health inequities,” the CDC states in a press release.

Women from racial and ethnic minority groups already face a disproportionate burden of cervical and breast cancers in the United States: Black women and Hispanic women have the highest rates of cervical cancer incidence (8.3 and 8.9 per 100,000 women, respectively, vs. 7.3 per 100,000 among White women) and the highest rates of cervical cancer deaths. Black women have the highest rate of breast cancer death (26.9 per 100,000 women, vs. 19.4 per 100,000 among White women), the study authors explain.

Although the volume of screening began to recover in May 2020 – test volumes for breast and cervical cancer were 39% and 40% below the 5-year average by June 2020 – breast cancer screening in rural areas remained 52% below the 5-year average, they report.

The findings were published online June 30 in Preventive Medicine.

“This study highlights a decline in cancer screening among women of racial and ethnic minority groups with low incomes when their access to medical services decreased at the beginning of the pandemic,” Dr. DeGroff comments in the CDC press release.

The findings “reinforce the need to safely maintain routine health care services during the pandemic, especially when the health care environment meets COVID-19 safety guidelines,” she adds.

The investigators used NBCCEDP administrative and program data reported to the CDC by awardees – organizations that receive funding to implement the NBCCEDP – to assess the impact of COVID-19 on the number of breast and cervical cancer screening tests administered through the program and the effects of COVID-19 on the availability of screening services and NBCCEDP awardees’ capacity to support partner clinics.

A total of 630,264 breast and 594,566 cervical cancer screening tests were conducted during the review period of January-June 2015-2020.

Despite COVID-related challenges, “a large number of awardees reported flexibility and creative efforts to reach women and support clinics’ resumption of clinical care, including screening, during the COVID-19 pandemic,” the authors write.

“[The] CDC encourages health care professionals to help minimize delays in testing by continuing routine cancer screening for women having symptoms or at high risk for breast or cervical cancer,” Dr. DeGroff commented. “The Early Detection Program can help women overcome barriers to health equity by educating them about the importance of routine screening, addressing their concerns about COVID-19 transmission, and helping them to safely access screening through interventions like patient navigation.”

Future studies will examine the effect of the pandemic on screening during the second half of 2020, when surges of COVID-19 and their timing varied geographically, they note.

The Food and Drug Administration has expanded the approval of secnidazole to include treatment of trichomoniasis in adults, according to a statement from manufacturer Lupin Pharmaceuticals.

Trichomoniasis vaginalis is a common, nonviral, curable sexually transmitted disease that affects approximately 3 million to 5 million adults in the United States each year; the infection can linger for months or years if left untreated, and may have a negative impact on reproductive health. The drug was approved for the treatment of bacterial vaginosis in 2017.

The availability of a single-dose oral treatment for both trichomoniasis and bacterial vaginosis may help improve adherence and reduce risk factors associated with these conditions, including pelvic inflammatory disease and other sexually transmitted infections, according to the statement.

The approval for the new indication was based primarily on data from a phase 3 clinical trial in which women with a confirmed trichomoniasis diagnosis were randomized to a single dose of 2 g oral secnidazole or a placebo. Secnidazole showed a 92.2% cure rate for patients with trichomoniasis, compared with placebo, based on cultures collected 6-12 days after dosing. Cure rates in subsets of patients with HIV and bacterial vaginosis were 100% and 95%, respectively.

The most common treatment-related adverse events were vulvovaginal candidiasis and nausea, each reported in 2.7% of study participants. The study findings were published in March 2021 in Clinical Infections Diseases.

Secnidazole also is approved for treatment of trichomoniasis in men, based on data from four open-label studies, one with men only and three including both men and women, according to the statement.

Secnidazole showed a 92.2% cure rate for patients with trichomoniasis, compared with placebo, based on cultures collected 6-12 days after dosing. Cure rates in subsets of patients with HIV and bacterial vaginosis were 100% and 95%, respectively.

The most common treatment-related adverse events were vulvovaginal candidiasis and nausea, each reported in 2.7% of study participants. The study findings were published in March 2021 in Clinical Infections Diseases.

Secnidazole also is approved for treatment of trichomoniasis in men, based on data from four open-label studies, one with men only and three including both men and women, according to the statement.

Full prescribing information for secnidazole is available here.

Pfizer is suspending distribution of the antismoking treatment Chantix after heightened levels of the carcinogen N-nitrosodimethylamine (NDMA) were found in some lots of the pills.

The pharmaceutical company is also recalling some lots of Chantix that may have high levels of NDMA, Reuters reported.

Pfizer told Reuters the distribution pause was ordered out of abundance of caution while further testing is conducted. The FDA approved varenicline, which is marketed as Chantix, in 2006.

“The benefits of Chantix outweigh the very low potential risks, if any, posed by nitrosamine exposure from varenicline on top of other common sources over a lifetime,” Pfizer spokesperson Steven Danehy said in an email, according to Reuters.

The FDA has not issued a recall on Chantix. In Canada, however, health authorities on June 8 instituted a recall for Champix, the name under which the drug is sold in that nation.

The Chantix website says it’s a 3- to 6-month treatment that helps people overcome the need to smoke tobacco. The website says more than 13 million people have been prescribed Chantix.

Other health concerns have been raised about Chantix, such as mental health side effects.

In 2016, however, researchers concluded Chantix did not appear to raise the risk of serious health disorders such as depression, anxiety, and suicidal thoughts.

The U.S. Food and Drug Administration has granted breakthrough therapy designation for lecanemab (Eisai/Biogen), an investigational anti-amyloid beta (Abeta) protofibril antibody for the treatment of Alzheimer’s disease.

Lecanemab (formerly BAN2401) is a humanized monoclonal antibody that selectively binds to large, soluble aggregated Abeta protofibrils. The antibody was developed following the discovery of a mutation in amyloid precursor protein that leads to a form of Alzheimer’s disease that is marked by particularly high levels of Abeta protofibrils.

“As such, lecanemab may have the potential to have an effect on disease pathology and to slow down the progression of the disease,” Eisai and Biogen said in a joint news release.

The breakthrough therapy designation for lecanemab is based on results of a randomized, double-blind, phase 2b proof-of-concept study published April 17 in Alzheimer’s Research & Therapy.

The study enrolled 856 patients with mild cognitive impairment (MCI) due to Alzheimer’s disease and mild Alzheimer’s disease with confirmed presence of amyloid pathology.

At the highest doses, treatment with lecanemab led to a reduction in brain amyloid accompanied by a consistent reduction of clinical decline across several clinical and biomarker endpoints.
 

Phase 3 testing underway

In March, Eisai and Biogen completed enrollment in a phase 3 study designed to confirm the safety and efficacy of lecanemab in patients with symptomatic early Alzheimer’s disease. 

The CLARITY AD study includes 1,795 patients with early Alzheimer’s disease, and initial results are expected by the end of September 2022. The core study will compare lecanemab against placebo on the change from baseline in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) at 18 months. The study will also evaluate the long-term safety and tolerability of lecanemab in the extension phase and whether the long-term effects of lecanemab, as measured by the CDR-SB at the end of the core study, are maintained over time.

Additionally, the phase 3 AHEAD 3-45 clinical study is currently exploring lecanemab in adults with preclinical Alzheimer’s disease (clinically normal but with intermediate or elevated brain amyloid).

On June 7, the FDA – amid significant controversy – approved aducanumab (Aduhelm), the first anti-amyloid agent for the treatment Alzheimer’s disease, disregarding the recommendation by its own advisory panel not to approve the drug. Three members of the FDA’s Peripheral and Central Nervous System Drugs Advisory Committee subsequently resigned in protest following the agency’s approval of aducanumab.

In addition, the high-profile consumer advocacy group Public Citizen sent a letter to the secretary of the U.S. Department of Health & Human Services demanding the removal of three FDA officials, including acting FDA Commissioner Janet Woodcock, MD.

The U.S. Food and Drug Administration has provided a detailed and documented account of how it arrived at its decision to approve the controversial Alzheimer’s drug aducanumab (Aduhelm, Biogen/Eisai), including the release of several internal documents.

In a letter sent to members of the FDA’s Center for Drug Evaluation Research (CDER), CDER Director Patrizia Cavazzoni, MD, noted that in view of the “fierce public debate” that erupted immediately following the drug’s approval, she felt compelled to explain how the agency came to its decision.

Also publicly released today on the FDA’s updated aducanumab landing page was “the first set of review memos,” for the drug.

“We’re releasing these documents with the intent of informing public discourse – providing interested parties with the opportunity to explore the data that helped shape our decision to grant accelerated approval,” Dr. Cavazzoni wrote. “The rest of the approval package will be released over the next several days,” she added.
 

Immediate backlash

The FDA’s June 7 approval of aducanumab was met with instant backlash. In November 2020, the agency’s Peripheral and Central Nervous System Drugs Advisory Committee voted nearly unanimously to not vote in favor of approval because of a lack of evidence proving its efficacy.

Since the drug was approved, three of the advisory committee’s members resigned in protest. In addition, the high-profile consumer advocacy group Public Citizen sent a letter to the secretary of the U.S. Department of Health & Human Services demanding the removal of three FDA officials, including acting FDA Commissioner Janet Woodcock, MD.

In its letter, the group noted that the FDA’s decision “showed a stunning disregard for science, eviscerated the agency’s standards for approving new drugs, and ranks as one of the most irresponsible and egregious decisions in the history of the agency.”

Even the Alzheimer’s Association, which was a staunch supporter of the drug throughout its development process and applauded its approval, expressed outrage over its more than $56,000-a-year cost to patients and called the price “simply unacceptable” in a statement.

In the June 23 letter, the CDER director noted, “this was one of the most complex applications in recent history” and admitted that deliberations were lengthy and difficult.

“It’s also not surprising, in fact it was to be expected, that there would be different viewpoints about the data, including dissenting opinions about the approval decision,” Dr. Cavazzoni wrote.

However, this “is what scientific debate is all about, and while difficult at times, it should be celebrated,” she added. “Please know that every opinion was heard, and the approval is a direct reflection of this open and robust scientific and regulatory debate.”
 

Accelerated approval pathway

Documents newly posted to the FDA’s aducanumab landing page include CDER’s Office of Neurology’s Summary Review Memorandum, which includes details on the basis for the approval; the Concurrence Memorandum from the director of CDER’s Office of New Drugs; and the Concurrence Memorandum from Dr. Cavazzoni.

“The remaining scientific review documents in the Aduhelm action package are not yet available but will be made available to the public as soon as the internal process of review and redaction is complete,” the FDA noted on its site.

In the document FDA’s Decision to Approve New Treatment for Alzheimer’s Disease, Dr. Cavazzoni noted that the “highly complex” data included in the submission package for the drug “left residual uncertainties regarding clinical benefit.”

However, after listening to the patient community and reviewing all the data, the FDA chose to use the Accelerated Approval pathway, deciding that the potential benefit to patients outweighed the drug’s risks.

Of two phase 3 trials, only one met its primary endpoint. However, in all trials, including earlier studies, “Aduhelm consistently and very convincingly reduced the level of amyloid plaques in the brain in a dose- and time-dependent fashion,” Dr. Cavazzoni wrote.

“It is expected that the reduction in amyloid plaque will result in a reduction in clinical decline,” she added.

Dr. Cavazzoni noted that although the Advisory Committee did not agree that clinical benefit from one trial meeting its primary endpoint was enough for approval, “the option of Accelerated Approval was not discussed” at that time.

This type of approval “is based on a surrogate or intermediate clinical endpoint, in this case reduction of amyloid plaque in the brain” and requires post-approval studies to verify clinical benefit.

Dr. Cavazzoni added that the drug could still be removed from the market if its confirmatory trial does not verify this type of benefit.
