Is lecanemab the key to changing the course of Alzheimer’s disease?


Studying the Effects of Lecanemab on Amyloid Counting and Memory Loss in Early-Type Alzheimer’s Disease

Lecanemab works by binding to an Alzheimer’s hallmark and is not a cure. In late November, results from a Phase 3 trial published in The New England Journal of Medicine proved that lecanemab reduced markers of amyloid in early Alzheimer’s disease, and was associated with less decline in cognitive function than placebo.

Maria Carrillo is the chief science officer of the Alzheimer’s Association. The data is positive.

Alzheimer’s causes the brain to shrink and this is a sign that the brain is dying. Alzheimer’s drugs were supposed to limit the size of the disease, not accelerate it.

A long list of antibodies that target theamyloid did not slow down the decline in memory and thinking associated with Alzheimer’s. The amyloid hypothesis, in which it is said that amyloid is a cause of brain cell loss, was questioned after so many drugs failed.

Medicare will only cover the drug for patients in clinical trials after Aduhelm received accelerated approval. The agency said it was unwilling to offer wider coverage for an Alzheimer’s drug that had not clearly shown it could preserve memory and thinking.

The drug was given accelerated approval based on its ability to remove amyloid from the brain. The FDA is likely to consider a full approval later this year, after reviewing the evidence that the drug also helps preserve mental function.

The most dangerous adverse events for the lecanemab group was related to the brain swelling and amyloid-relatedimaging abnormality that can become life threatening.

Patients can experience brain damage in rare cases. Two deaths have been tied to lecanemab, but both patients had other conditions that could have contributed to the outcome.

“What we know is that a small portion of individuals will experience symptoms and when they arise, they are mild to moderate,” Cohen says.

ARIA can lead to hospitalization or long term impairment in some people, but other people don’t have symptoms. It was shown that people with a gene called APOE4 are more likely to suffer from Alzheimer’s disease. ARIA were not as common as APOE4 noncarriers.

Drug developers and researchers must prove that the changes are benign and do not represent a significant adverse event.

The committees recommended that the FDA document its meetings with drug companies, as well as establish a protocol for briefings and advisory committees, while updating its guidance for Alzheimer’s drugs.

The report was done over 18 months by two House committees. It is sharply critical of Biogen, maker of the medication Aduhelm.

The report says that the price for Aduhelm was set to make history for the company, and that the drug was thought to be an unprecedented financial opportunity. Biogen priced Aduhelm at $56,000 per year, even though its actual effects on a broad patient population were unknown.

Drug Pricing for Alzheimer’s Disease: Regulatory Issues in FDA-Provised Trials and Clinical Trials of an Alternative Therapies

The number of people in the United States who are afflicted with Alzheimer’s will grow to over 13 million by 2060.

Dementia, including Alzheimer’s, is one of the “costliest conditions to society,” according to the Alzheimer’s Association. In 2022 alone, Alzheimer’s and other dementias cost the US $321 billion, including $206 billion in Medicaid and Medicare payments, the association says.

The agency then collaborated with Biogen to draft a document used to brief an independent advisory committee that met in November 2020. The trial results were mixed, with only one showing a small benefit to patients.

In that meeting, no one on the committee voted to say that the studies showed the drug was effective in treating Alzheimer’s.

The committees also recommended that companies clearly communicate safety and efficacy concerns to the FDA and consider the value assessments made by outside experts when setting drug prices.

The agency says it is reviewing the committees’ findings and recommendations and says its own review found that the interactions with Biogen were appropriate.

“It is the agency’s job to frequently interact with companies in order to ensure that we have adequate information to inform our regulatory decision-making. We will continue to do so, as it is in the best interest of patients. Changes consistent with the Committee’s recommendations have already started by the agency.

The US Food and Drug Administration could decide this week whether to grant accelerated approval to the experimental dementia drug lecanemab, according to Eisai and Biogen, the companies that make the drug.

The Alzheimer’s Association has asked the government to provide full and unrestricted coverage for FDA-approved Alzheimer’s treatments.

A participant’s death in a clinical trial of an anti-depressant drug for Alzheimer’s disease may be linked to the experimental drug

Six deaths occurred in the leCanemab group and seven deaths occurred in the placebo group, according to the trial results.

Even if the FDA offers accelerated approval of the drug, it will still be studied in more robust trials. And if those trials confirm that the drug provides a clinical benefit, the FDA could grant traditional approval. But if the confirmatory trial does not show benefit, the FDA has regulatory procedures that could lead to taking the drug off the market.

The death of a participant in a clinical trial of an antibody treatment for Alzheimer’s disease, which is now under consideration by the US Food and Drug Administration, may be linked to the experimental drug, a new report shows.

The company and Northwestern Medicine pointed to a response published alongside the new report from clinicians and researchers who were involved in the lecanemab clinical trials.

A placebo arm is not used in an open-label extension because a previous part of the trial has shown a lot of potential.

The patient was not the only one who died during the open-arm extension. The health publication Stat reported that an investigator told it about the death of another participant who had bleeding in the brain that may have been related to the drug. In that case, drugmaker Eisai pointed to other possible factors.

The research also showed that about 2.8% of trial participants who took the drug had a symptomatic side effect called ARIA-E, which involves swelling in the brain. None of the people who received placebos had that.

Cohen thinks the death of the patient is related to the blood clot drug, but he thinks the combination of it and lecanemab makes it hard for us to make a definitive determination.

The patient became agitated and had communication problems after they gave him the medicine to control the bleeding. The patient had a lot of seizures.

The person got the tube in their windpipe after being in the hospital. The patient died despite the supportive care.

They said that the brain bleed could have been connected to high blood pressure when the patient had a stroke. A drug used for atrial fibrillation may have contributed to the trial participant’s demise.

CNN sought an interview with the authors of the new report but was turned down byNorthwestern Medicine, which said in a statement that they were trying to provide data to the medical and scientific community.

The doctors also write in the response that other patients who have gotten t-PA have died with these amyloid deposits within blood vessels in the brain.

The safety of the drug “looks very acceptable,” she said. It seems reasonable for the patient population, because it’s within the range of adverse events we expected.

She stated that if the FDA approves the treatment then it is up to the patient’s doctor to decide if it is best for the patient to take anticoagulants or other risk factors.

The FDA’s accelerated approval was expected, said Dr. Richard Isaacson, director of the Alzheimer’s Prevention Clinic in the Center for Brain Health at Florida Atlantic University’s Schmidt College of Medicine.

I would do genetic testing first. He said that he would have a discussion with his patients. If someone is having side effects, if they are on a blood-thinning medication, if they are having a problem, they should seek medical attention immediately and discuss it with their treating physician.

What Leqembi can do for Alzheimer’s disease and how to coordinate access and care for it: The potential costs of a new neuroimaging drug

The new drug, which is given intravenously every other week, removes a substance called amyloid from the brain. Sticky amyloid plaques are a hallmark of Alzheimer’s, though many previous drugs that targeted amyloid failed to slow down patients’ loss of mental abilities.

“It’s not a cure. The disease isn’t stopped completely by it. “It doesn’t make people better,” he says. “But it does slow down progression in very mild disease.”

“Maybe you could keep driving for an extra six months or a year,” she says. “Maybe you can keep doing your checks for an additional six months to a year.”

To qualify for treatment, people need to undergo tests showing that they are in the early stages of dementia and that their brains contain the amyloid deposits that are a hallmark of Alzheimer’s. That process is likely to include at least two visits to specialists, who are in short supply.

Medicare won’t cover it until Leqembi gets full FDA approval. The reason has to do with the earlier Alzheimer’s drug, Aduhelm.

“One of the potential solutions would be to see if we can pool all of the dementia patients who are covered under different plans into a single risk pool and then provide coordinated access and care to those patients,” Hlávka says.

If people with dementia are able to delay nursing home care, then the government would be able to balance the cost of the drug against potential savings. It would make it easier for the government to negotiate on a price for Leqembi.

Since the early 1970s, Medicare has run a special program for people of all ages whose kidneys are failing. The program costs Medicare over $9 billion a year.
