Previously administered via intravenous infusion, LEQEMBI® is now available as a subcutaneous injection. This shift promises to reduce the burden on both patients and healthcare providers,eliminating the need for lengthy infusion appointments and potentially expanding access to care. The FDA’s decision is based on data demonstrating the efficacy and safety of the subcutaneous formulation in maintaining the benefits achieved during the initial intravenous treatment phase.
According to the Alzheimer’s Association, over 6.7 million Americans are currently living with Alzheimer’s disease in 2024. Alzheimer’s Association This approval signifies a crucial step forward in providing more convenient and accessible treatment options for those affected.
How LEQEMBI® Works
LEQEMBI® is an antibody-based therapy that targets and helps remove amyloid plaques, one of the hallmarks of Alzheimer’s Disease, from the brain. While not a cure, the treatment aims to slow the progression of cognitive decline in individuals with early-stage disease. The subcutaneous injection delivers the same active ingredient as the intravenous formulation, ensuring continuity of care with a more patient-friendly delivery method.
Did You Know? Alzheimer’s Disease is the most common cause of dementia, accounting for 60-80% of cases.

What impact do you think easier administration methods will have on patient adherence to Alzheimer’s treatments? And how important is the continued investment in research for potential Alzheimer’s cures?
Understanding Alzheimer’s Disease
Alzheimer’s Disease is a progressive brain disorder that gradually destroys memory and thinking skills.It is not a normal part of aging, although the risk increases with age. Early detection and diagnosis are crucial for maximizing the benefits of available treatments and supportive care. Symptoms typically begin with mild memory loss and can progress to include confusion, difficulty with language, and changes in personality.
Frequently Asked Questions about LEQEMBI®
- what is alzheimer’s Disease? Alzheimer’s Disease is a brain disorder that causes a slow decline in memory, thinking, and reasoning skills.
- What does LEQEMBI® treat? LEQEMBI® is approved for the maintenance treatment of early alzheimer’s Disease.
- How is the subcutaneous injection administered? The injection is administered under the skin, offering a more convenient option to intravenous infusion.
- What are the potential side effects of LEQEMBI®? Potential side effects can vary, and it’s critically important to discuss them with your healthcare provider.
- Is LEQEMBI® a cure for Alzheimer’s? No, LEQEMBI® is not a cure, but it aims to slow the progression of the disease.
- Who is eligible for LEQEMBI® treatment? Eligibility criteria are specific and steadfast by a healthcare professional based on disease stage and other factors.

What is cerebral amyloid angiopathy (CAA) and how does it relate to LEQEMBI® eligibility?
FDA Approves Biogen’s Lecanemab-irmb (LEQEMBI®, IQLIK™) as First Maintenance Dosing Treatment for Early Alzheimer’s Disease
Understanding Lecanemab: A New Era in Alzheimer’s Treatment
The Food and Drug Administration (FDA) has granted approval for Biogen’s lecanemab-irmb, marketed under the brand names LEQEMBI® and IQLIK™, marking a notable milestone in the fight against Alzheimer’s disease. This approval isn’t just for treatment; it’s specifically for maintenance dosing – a long-term approach aimed at slowing the progression of early Alzheimer’s. This represents the first such treatment option available, offering renewed hope for patients and families.
How Lecanemab Works: Targeting Amyloid Plaques
Lecanemab is an antibody designed to target and clear amyloid plaques, a hallmark of Alzheimer’s disease. These plaques are believed to play a crucial role in the neurodegeneration that characterizes the condition.
Here’s a breakdown of the mechanism:
Amyloid Beta: Lecanemab specifically targets aggregated forms of amyloid beta protein.
Plaque Reduction: By binding to these plaques, the drug facilitates their removal from the brain.
Nervous System Protection: Reducing amyloid burden is hypothesized to protect nerve cells and slow cognitive decline.
According to research from Deutsche Alzheimer [https://www.deutsche-alzheimer.de/fileadmin/alz/pdf/factsheets/Faktencheck-lecanemab-05-2024.pdf], Lecanemab demonstrably reduces amyloid-Ablagerungen (deposits) in the brains of Alzheimer’s patients.
Who is Eligible for LEQEMBI® (Lecanemab)?
LEQEMBI® isn’t a cure, and it’s not for everyone. The FDA approval specifies that it’s intended for individuals with:
Early Alzheimer’s Disease: Specifically, those with mild cognitive impairment (MCI) or mild dementia stage of the disease.
Confirmed Amyloid Pathology: Patients must have confirmed presence of amyloid plaques in the brain, typically verified through PET scans or cerebrospinal fluid analysis.
Asymptomatic Status: The treatment is for those already diagnosed with early Alzheimer’s, not for preventative use in those without symptoms.
The Clinical Trial Data: What Did the Studies Show?
The approval of lecanemab was based on the results of the Phase 3 Clarity AD clinical trial. Key findings include:
- Cognitive Decline Slowed: Participants receiving lecanemab experienced a statistically significant slowing of cognitive decline compared to those receiving a placebo.
- Amyloid Reduction: PET scans confirmed a significant reduction in amyloid plaques in the brains of treated patients.
- Treatment Duration: The trial demonstrated benefits over an 18-month period.
It’s crucial to note that the effect size was modest, meaning the slowing of decline wasn’t dramatic, but it was statistically and clinically meaningful.
Potential Side Effects and Safety Considerations
Like all medications, lecanemab carries potential risks. The moast common side effects observed in clinical trials include:
Amyloid-Related imaging Abnormalities (ARIA): These are brain swelling or microbleeds detected on MRI scans. ARIA can be asymptomatic, but in some cases, can cause symptoms like headache, confusion, or vision changes.
Infusion-Related Reactions: Some patients experienced reactions during the intravenous infusion of the drug, such as fever, chills, nausea, and changes in blood pressure.
Other Side Effects: Fatigue,falls,and diarrhea were also reported.
Careful monitoring with regular MRI scans is crucial to detect and manage ARIA.Patients with a history of cerebral amyloid angiopathy (CAA) are at higher risk and may not be eligible for treatment.
The Maintenance Dosing Schedule: What to Expect
LEQEMBI® is administered intravenously every two weeks. The maintenance dosing schedule is designed to sustain the benefits observed in clinical trials.
Initial Phase: An initial higher dose is given, followed by a transition to the maintenance dose.
Long-Term commitment: Maintenance dosing is intended to be continued for as long as the patient is benefiting from the treatment and tolerating it well.
Regular Monitoring: Ongoing monitoring with MRI scans and clinical assessments is essential to assess treatment response and safety.
