Donanemab vs Lecanemab: Which drug is better for early Alzheimer’s?


Until recently, no medicine has successfully targeted the underlying cause of early Alzheimer's disease, making the arrival of two new drugs a historical advancement that potentially impacts millions of Americans.

Introducing Donanemab and Lecanemab

In a groundbreaking development, two new medicines, Donanemab (also known as Kisunla) and Lecanemab (also known as Leqembi), offer new hope for those in the early stages of Alzheimer's disease drug development. 

These innovative treatments signify a transformative shift in the approach to managing conditions like Alzheimer’s. Unlike previous medications that primarily focused on alleviating symptoms, Donanemab and Lecanemab target the underlying disease process, aiming to slow its progression and offer patients a better quality of life. 

However, there’s a lot to consider before choosing Donanemab or Lecanemab, including cost, time commitment, and potential side-effects. In this article, we’ll break down everything you need to know about these innovative disease–modifying treatments. 

Donanemab vs Lecanemab: Recent Approvals and Innovations

The Food and Drug Administration recently approved Donanemab marking a significant milestone in Alzheimer's treatment. The FDA approval follows the earlier acceptance of Lecanemab. Unlike older medicines that merely alleviate symptoms, these new drugs aim to slow down the progression of the disease itself, providing a more substantial impact on patients' lives.

This breakthrough not only highlights the advancements in medical research but also underscores the importance of continued innovation and support for Alzheimer's patients and their loved ones. As we embrace disease modifying treatments, we open doors to better outcomes for all impacted by this devastating disease.

How Do These Medicines Work?

Both Donanemab and Lecanemab target amyloid, a protein found in the brain. Amyloid forms clumps, known as plaques, that build up in the brain. These clumps are believed to damage brain cells in Alzheimer's patients. Clinical trials have shown that these medicines can remove the amyloid, potentially slowing down memory loss and other cognitive declines associated with Alzheimer's.

By focusing on removing amyloid plaques, Donanemab & Lecanemab aim to mitigate their harmful effects, potentially slowing down the progression of memory loss and other cognitive declines associated with Alzheimer's.

Donanemab and Lecanemab are important because they target the root causes of Alzheimer's disease. As scientists continue to research and test these treatments, the hope for better Alzheimer's care keeps improving.

Who Are These Medicines For?

Both Donanemab & Lecanemab  are designed for individuals with mild memory problems or early-stage Alzheimer's dementia. Patients need to have amyloid plaques in their brains, which can be confirmed through special scans or tests. By specifically targeting patients with amyloid build up, we ensure that treatments are the most effective possible.

Donanemab vs. Lecanemab: Side by Side Comparison

Donanemab (Kisunla)

  • Treatment Schedule: Monthly hospital visits for intravenous (IV) treatment, usually in outpatient infusion centers or possibly at home. 
  • Cost: Approximately $32,000 per year.
  • Duration: Many patients can stop after about 18 months if amyloid levels decrease significantly.
  • Efficacy: In trials, Donanemab slowed the decline in memory and thinking skills by about 35%.

Lecanemab (Leqembi)

  • Treatment Schedule: Hospital visits twice a month for IV treatment, also available in outpatient settings or potentially at home.
  • Cost: Approximately $26,500 per year.
  • Duration: Usually taken long-term.
  • Efficacy: In trials, it slowed the decline in memory and thinking skills by about 27%.

While these innovative medicines offer great potential in treating early Alzheimer’s, without insurance coverage, advanced treatments like Donanemab and Lecanemab can be very expensive. 

That’s why it’s so important to manage insurance well to help cover these costs. Experts at Harmonic Health can help you get insurance approvals, handle claim denials, and find assistance programs. This support makes these treatments more affordable and ensures patients get the care they need. 

Side Effects and Risks 

Both medicines can cause serious side effects such as brain swelling or small bleeds in the brain, known as ARIA (Amyloid-Related Imaging Abnormalities). Although this may sound alarming, it is important to understand that ARIA is often asymptomatic and typically resolves on its own without requiring any changes to the treatment regimen.

In some cases, adjusting or temporarily pausing the treatment might be necessary, but even then, ARIA usually resolves completely. To ensure patient safety, regular brain scans are an integral part of the treatment protocol. 

While serious ARIA-related events are rare, it is essential for patients to be aware of other common side effects, such as infusion-related reactions and headaches. Despite these potential side effects, many patients and doctors believe that the benefits of these new treatments outweigh the risks, particularly for those in the early stages of Alzheimer's disease.

What About Costs and Insurance?

Insurance coverage for both medicines is still being determined. Medicare patients might pay up to $5,300 to $6,400 per year out-of-pocket. These costs may change based on the duration of the treatment and specific insurance decisions. 

It's essential for patients to discuss financial aspects with their healthcare providers and insurance companies to understand their options fully. If you need any assistance navigating these hurdles, contact Harmonic Health for expert advice.

Things to Consider

When considering these treatments, here are some factors to consider:

  • Transportation: Is the patient able to make hospital visits once or twice a month?
  • Monitoring: Is the patient willing to have regular brain scans and blood tests?
  • Consultation: What are the potential benefits and risks of Donanemab and Lecanemab for the patient’s specific condition?

If you feel these new medications could be a good fit for you or a loved one, consult with a doctor to make an informed decision on Donanemab versus Lecanemab.

The Bigger Picture

Donanemab and Lecanemab mark a revolutionary step forward in Alzheimer's treatment. While they are not considered cures, these medications can slow symptom progression, allowing patients more time with improved cognitive function. 

Conveniently administered in outpatient settings or even at home, they make treatment more accessible. Though side effects like ARIA can occur, they are generally manageable and often resolve on their own.

As ongoing research sheds light on the long-term benefits, Donanemab and Lecanemab present new options for those in the early stages of Alzheimer's. However, it's essential to have a detailed conversation with your doctor to determine if these treatments are suitable for you or your loved one. Your doctor can help assess your specific health needs and balance the potential benefits with any risks involved.
