The Netherlands will not reimburse the cost of lecanemab (Leqembi®), a recently approved drug for early-stage Alzheimer’s disease, after the Zorginstituut Nederland – the country’s healthcare institute – concluded it offers insufficient benefit to patients given its potential for serious side effects. The decision, announced on Wednesday, February 18, 2026, marks a setback for those hoping for a breakthrough in treating the debilitating neurodegenerative disease.
While lecanemab represents the first medication aimed at slowing the progression of Alzheimer’s, the Zorginstituut’s assessment found the clinical improvements experienced by patients were too small to justify the drug’s cost and risks. The institute advises the Minister of Health, Welfare and Sport against including lecanemab in the standard benefits package of health insurance. This means patients will likely have to pay for the treatment out-of-pocket, if it becomes available at all.
Limited Efficacy and Significant Risks
Alzheimer’s disease, a progressive condition affecting memory, thinking, and behavior, impacts a significant portion of the population. Symptoms typically include forgetfulness, confusion, and difficulty with language. According to the Zorginstituut Nederland, lecanemab is designed for individuals in the early stages of the disease, specifically those with mild cognitive impairment and mild dementia. However, research indicates that even in this group, the drug’s effect on slowing cognitive decline is modest.
More concerningly, lecanemab carries a risk of serious side effects, including brain bleeding and swelling. These adverse events can sometimes be severe, leading to paralysis, speech difficulties, or even death, though such outcomes are rare. Patients may not always experience noticeable symptoms from these side effects, but the potential for harm weighed heavily in the Zorginstituut’s decision. The drug is administered via bi-weekly injections in a hospital setting, adding to the logistical and financial burden.
How Lecanemab Works and Why It Fell Short
Lecanemab functions by targeting and removing amyloid plaques, protein deposits that accumulate in the brains of people with Alzheimer’s disease. While the exact cause of Alzheimer’s remains unknown, these plaques are believed to play a role in the disease’s progression. The drug’s mechanism of action – clearing these protein build-ups – was not enough to demonstrate a substantial clinical benefit for patients, according to the Zorginstituut’s evaluation. The institute concluded that the limited impact on disease progression did not outweigh the potential for serious adverse reactions.
The cost of lecanemab is also a significant factor. Estimates place the annual cost of treatment at around €25,000 per patient, excluding additional expenses related to hospital visits and brain scans, as reported by Nationale Zorggids. Experts suggest that these funds could be better allocated to proven effective care and support services for Alzheimer’s patients and their families.
A Disappointment for Patients and Families
The decision not to reimburse lecanemab is a significant disappointment for patients and their loved ones who had hoped for a more effective treatment option. As stated in AD.nl, it is a “big disappointment” that the drug does not represent a breakthrough. Despite the setback, research into new Alzheimer’s treatments continues, and other potential therapies are currently under development. The Zorginstituut is also expected to review another Alzheimer’s drug, donanemab, at a later date, though a timeline for that assessment has not yet been announced.
The debate surrounding lecanemab highlights the challenges of developing and evaluating treatments for complex diseases like Alzheimer’s. Balancing the potential benefits of a new drug against its risks and costs requires careful consideration, and the Zorginstituut’s decision reflects a commitment to ensuring that healthcare resources are used effectively.
Looking ahead, the focus will remain on improving the quality of life for individuals living with Alzheimer’s disease and supporting ongoing research efforts to find more effective treatments. The need for comprehensive care, including early diagnosis, supportive therapies, and respite care for caregivers, remains paramount.
