Australia Approves Lecanemab (Leqembi) for Early-Stage Alzheimer’s Treatment
In a significant advancement for Alzheimer’s disease management, Australia’s Therapeutic Goods Administration (TGA) has approved lecanemab, marketed as Leqembi, for the treatment of early-stage Alzheimer’s disease. This decision marks a pivotal moment in dementia care, offering new hope to patients and families affected by this condition.
What Is Lecanemab (Leqembi)?
Lecanemab is a monoclonal antibody developed by Eisai and Biogen, designed to target and reduce amyloid plaques in the brain—a hallmark of Alzheimer’s disease. Administered via intravenous infusion every two weeks, Leqembi has demonstrated the ability to slow cognitive decline in individuals with mild cognitive impairment and mild dementia due to Alzheimer’s. However, it is not a cure and is intended for early-stage patients who are non-carriers or heterozygotes of the apolipoprotein E ε4 (ApoE ε4) gene variant.
Approval Process and Criteria
Initially rejected by the TGA in October 2024 due to safety concerns, particularly regarding brain swelling and bleeding in patients carrying the ApoE ε4 gene, lecanemab’s approval was reconsidered following additional data submissions and discussions with the manufacturer. The TGA’s revised decision allows its use in patients without two copies of the ApoE ε4 gene, provided they meet specific diagnostic criteria.
Monitoring and Safety Considerations
Patients receiving Leqembi must undergo regular MRI scans to monitor for amyloid-related imaging abnormalities (ARIA), including brain swelling and microhemorrhages. While these side effects are relatively rare, they can be more prevalent in individuals with the ApoE ε4 gene, underscoring the importance of personalized treatment plans and vigilant monitoring.
Implications for Alzheimer’s Treatment in Australia
The approval of Leqembi, alongside the earlier approval of Kisunla (donanemab), represents a significant step forward in the treatment of early-stage Alzheimer’s disease in Australia. These therapies offer patients the potential to slow disease progression, thereby extending quality of life. However, access remains a challenge due to high treatment costs and the need for inclusion in the Pharmaceutical Benefits Scheme (PBS) to reduce financial barriers.
Why This News Is Important
Advancement in Alzheimer’s Treatment
The approval of Leqembi introduces a new therapeutic option for patients in the early stages of Alzheimer’s disease, addressing an unmet need in dementia care. By targeting the underlying pathology of the disease, Leqembi offers a disease-modifying approach rather than merely alleviating symptoms.
Impact on Patients and Families
For individuals diagnosed with early-stage Alzheimer’s, Leqembi provides a potential to slow cognitive decline, thereby preserving independence and quality of life for a longer period. This development brings renewed hope to patients and their families, who have long awaited effective treatment options.
Economic and Healthcare Considerations
The high cost of Leqembi poses challenges for widespread accessibility. Without inclusion in the PBS, many patients may find the treatment financially prohibitive. Advocacy for government support and insurance coverage is crucial to ensure equitable access to this promising therapy.
Scientific and Medical Community Response
The medical community has largely welcomed the approval of Leqembi, emphasizing the importance of early diagnosis and intervention in Alzheimer’s disease. Healthcare professionals stress the need for comprehensive patient monitoring and informed decision-making regarding treatment options.
Future Directions in Alzheimer’s Research
The approval of Leqembi and Kisunla signals a shift towards disease-modifying therapies in Alzheimer’s treatment. Ongoing research into amyloid-targeting drugs and other innovative approaches holds promise for further advancements in the management of Alzheimer’s disease.
Historical Context
Early Alzheimer’s Treatments
Historically, Alzheimer’s disease treatments have focused on symptom management, with limited efficacy in altering disease progression. The introduction of disease-modifying therapies like Leqembi represents a paradigm shift in Alzheimer’s care.
Development and Approval of Leqembi
Leqembi underwent rigorous clinical trials, demonstrating its ability to reduce amyloid plaques and slow cognitive decline in early-stage Alzheimer’s patients. Following initial regulatory challenges, additional data and discussions led to its approval in Australia, reflecting a commitment to advancing dementia care.
Global Perspectives on Alzheimer’s Treatment
The approval of Leqembi aligns with global trends towards developing and implementing disease-modifying therapies for Alzheimer’s disease. International collaborations and research initiatives continue to drive progress in understanding and treating this complex condition.

FAQs: Frequently Asked Questions
1. What is Lecanemab (Leqembi)?
Lecanemab, marketed as Leqembi, is a monoclonal antibody drug approved in Australia for early-stage Alzheimer’s disease. It targets and reduces amyloid plaques in the brain, helping slow cognitive decline in affected patients.
2. Who is eligible to take Leqembi in Australia?
Leqembi is approved for patients with early-stage Alzheimer’s who do not carry two copies of the ApoE ε4 gene variant. Patients must also have confirmed amyloid plaques in the brain.
3. How is Leqembi administered?
The drug is given via intravenous infusion every two weeks under medical supervision, with ongoing monitoring for safety.
4. What are the major side effects of Leqembi?
Patients may experience amyloid-related imaging abnormalities (ARIA), including brain swelling and microbleeds. These risks are higher in patients carrying the ApoE ε4 gene.
5. Why was Leqembi initially rejected by the TGA?
The Therapeutic Goods Administration (TGA) initially rejected Leqembi due to safety concerns related to brain swelling and bleeding in patients with the ApoE ε4 gene. Approval was granted after additional clinical data and discussions.
6. How does Leqembi impact Alzheimer’s disease treatment?
Unlike traditional symptom-managing drugs, Leqembi is a disease-modifying therapy. It slows the progression of early-stage Alzheimer’s by targeting amyloid plaques, improving patient quality of life.
7. Are there any cost considerations for patients?
Leqembi is expensive, and access may be limited unless it is included in Australia’s Pharmaceutical Benefits Scheme (PBS). Advocacy for PBS inclusion is ongoing.
8. What other Alzheimer’s drugs are available in Australia?
Another recently approved drug is Donanemab (marketed as Kisunla), which also targets amyloid plaques and slows cognitive decline in early-stage Alzheimer’s patients.
