Leqembi (lecanemab-irmb) has become the first drug approved by the US Food and Drug Administration (FDA) to slow the progression of Alzheimer’s disease (AD) symptoms, offering hope to millions of people affected by this devastating condition. A Phase III clinical trial demonstrated that Leqembi can effectively slow AD progression by approximately 27% over an 18-month period.
The groundbreaking drug works by targeting and eliminating the amyloid beta protein that forms plaques in the brains of AD patients. By removing these plaques, Leqembi helps to slow down the decline in cognitive function associated with the disease, providing much-needed relief for individuals with early AD characterized by mild cognitive impairment or mild dementia due to AD.
While the effectiveness of Leqembi in more advanced stages of AD remains uncertain, the approval of Donanemab, another disease-slowing drug, is anticipated by the end of the year. With these advancements, researchers are optimistic about the potential for improved treatments and outcomes for patients at all stages of the disease.
However, AD diagnosis confirmation still requires measuring beta-amyloid protein in spinal fluid or through brain PET scans, and potentially blood tests. These diagnostic measures are essential for determining eligibility for drugs like Leqembi.
The FDA’s approval comes with some precautions. To monitor any potential side effects, individuals taking Leqembi will need to undergo periodic MRI scans. This requirement limits eligibility to those who are able to undergo an MRI and may pose challenges for certain patient groups. Furthermore, certain genetic variations or health conditions may increase the risk associated with the drug.
Leqembi will be covered by Medicare, providing relief to those who need it most. However, physicians will need to perform specific clinical measures and enter patient data into a registry for the drug to be covered. Despite this, concerns have been raised about the drug’s availability due to its cost of $26,500 per year, potentially impacting underinsured or disadvantaged groups.
Like any medication, Leqembi has its own set of side effects. Patients may experience fever and flu-like symptoms during infusion, as well as brain edema and brain bleeding events. The burden of regular intravenous infusions every two weeks is an additional consideration for patients and their caregivers.
The approval of Leqembi represents a significant milestone in AD treatment, shedding light on the pressing need for more effective and accessible drugs with lower costs and patient burdens. As researchers continue to make progress in developing new treatments, it is hoped that these advancements will bring brighter prospects for individuals and families affected by Alzheimer’s disease.
