Rare Side Effects Suggested by Real-world Data Regarding Lecanemab for Alzheimer's Treatment
Lecanemab: Fighting Alzheimer's in the Real World
Hey there! The U.S. Food and Drug Administration (FDA) granted approval for lecanemab, a groundbreaking medication, to tackle the stubborn onset of Alzheimer's disease all the way back in 2023. But, like any battle, there are potential pitfalls.
First off, it's vital to understand that lecanemab comes with a lineup of combat side effects, similar to any other medication. These may include headaches, dizziness, muscle aches, and blurred vision. However, the most serious battle scars include amyloid-related imaging abnormalities (ARIA), such as brain swelling or bleeding. No cause for alarm just yet - in clinical trials, the occurrence of these heavier side effects were rare and manageable.
In the spine-tingling pages of the Clarity AD phase 3 clinical trial, published in 2022, researchers reported patients experiencing ARIA in minimal numbers - a mere 0.8% of participants suffered ARIA-E (edema/effusion) and 0.7% experienced ARIA-H (hemorrhage/hemosiderin deposition).
Fast-forward to a chilly 2023, when a brand-new study rehashed the Clarity AD findings, verifying that fortunate Alzheimer's warriors in the earliest stages of the disease could tackle the heavier ARIA side effects with relative ease.
What is this mysterious lecanemab?
In a recent operation spearheaded by radiant researchers at Washington University Memory Diagnostic Center, 234 shimmering 'soldiers' with early-stage Alzheimer's disease were recruited to face the battle alone. The average age of these brave troops? Around 74.
Barbara Joy Snider, the cunning commander-in-chief and ebullient professor of neurology at WashU Medicine, explained the magical properties of lecanemab:
Lecanemab Takes Aim at Amyloid Proteins
Barbara proudly announced lecanemab's expert marksmanship - a natural-born achiever, it targets those pesky amyloid proteins! These cunning enemies have the ability to misfold, causing them to interfere with brain activity and coagulate into nasty little clusters known as plaques - the hallmark of Alzheimer's.
When lecanemab swoops into battle, it's on a mission to destroy these plaques, thus reducing their presence in the brain over time. During the immense battle, patients saw a slowing of their cognitive decline. 18 months of grueling combat resulted in about 25-30% less memory and thinking loss for those connected to the power of lecanemab.
A deserves attention: Wading through ARIA
The new study revealed that a paltry 1.8% of patients at the earliest stage of Alzheimer's disease experienced ARIA symptoms, compared to a heftier 27% of participants with mild Alzheimer's disease. Snider pointed out that this revelation underscores the paramount importance of catching Alzheimer's disease in its initial stages.
A Silver Lining to a Potential Risks: Manageable Risks and Recovery
Snider and her dedicated team followed these brave warriors, discovering that 11 of them experienced ARIA symptoms. The effects, a majority of which disappeared within a few months, left no fatalities in their wake.
MNT Chats with Experts: Interpreting the Study
Acknowledging the Role of Lecanemab: John Dickson, MD, PhD
John, a sharp neurologist at Massachusetts General Hospital, shared his views on this monumental study.
A New Addition to the Fight: Lecanemab vs. Donanemab
John's opinion calls for further research to identify patients who may be at an increased risk of violent ARIA encounters. Finding that crucial data could help clinicians offer more informed recommendations to patients regarding the best options - whether that be lecanemab or its fierce competitor, donanemab.
Benefits vs. Side Effects: Manisha Parulekar, MD, FACP, AGSF, CMD
Manisha, the powerful director of Geriatrics at Hackensack University Medical Center, voiced her opinion on the study, pointing out the delicate struggle between benefits and side effects.
The Next Generation of Treatments: A Glimmer of Hope
Snider and her tireless team will continue to monitor their intriguing patients, eagerly awaiting more valuable insights on lecanemab's potential side effects and its continuous effect on slowing cognitive decline. The researchers are elated that they are now actively doling out lecanemab to appropriate patients. They eagerly anticipate future advancements in treatments for Alzheimer's disease.

- In the approach to battling Alzheimer's disease, there are potential pitfalls associated with medications like lecanemab.
- Side effects of lecanemab can include headaches, dizziness, muscle aches, and blurred vision, but the most serious side effects are amyloid-related imaging abnormalities (ARIA).
- The occurrence of heavier side effects such as brain swelling or bleeding in clinical trials was rare and manageable.4.
- Barbara Joy Snider, a professor of neurology at WashU Medicine, described lecanemab as a masterful medication that combats Alzheimer's disease.
- Lecanemab is a potent warrior created from antibodies, which are strategic warriors built within the immune system to target specific enemies.
- The main target of lecanemab is amyloid proteins, which can misfold and build up in the brain as plaques, causing cognitive decline.
- After 18 months of treatment with lecanemab, patients experienced about 25-30% less memory and thinking loss.
- No fatalities were reported in the study as a result of ARIA symptoms experienced by some patients.
- The researchers found that patients with very mild symptoms benefited more from lecanemab, reducing their cognitive decline by approximately 40-50%.
- When it comes to managing chronic diseases like Alzheimer's, holistic approaches that focus on health and wellness, fitness and exercise, mental health, and nutrition are essential.
- CBD, a natural compound found in cannabis, may also have potential benefits for managing symptoms of neurological disorders such as Alzheimer's disease.
- In addition to Alzheimer's disease, other neurological disorders such as dementia, Parkinson's disease, and multiple sclerosis can also affect seniors, and it's important to address these medical conditions in the workplace to support the overall wellness and productivity of employees.
