What side effects are associated with this type of intervention?

Common treatments for Alzheimer's Disease that target amyloid-beta plaques, such as Donanemab, include antibody-based therapies like solanezumab and aducanumab. These treatments have been associated with side effects such as infusion-related reactions, amyloid-related imaging abnormalities (ARIA), which can include brain swelling and microhemorrhages, and general symptoms like headache, dizziness, and nausea. Other common Alzheimer's treatments, such as cholinesterase inhibitors (e.g., donepezil) and memantine, can cause gastrointestinal issues, dizziness, and confusion.

What prior FDA approvals exist?

The FDA has approved several treatments for Alzheimer's Disease that target amyloid-beta plaques, similar to Donanemab. One notable example is Aducanumab, a monoclonal antibody that reduces amyloid-beta plaques in the brain. Aducanumab was approved based on its ability to decrease amyloid plaques, which are believed to contribute to the progression of Alzheimer's Disease. Other treatments include supportive medications like cholinesterase inhibitors (donepezil, rivastigmine, and galantamine) and NMDA receptor antagonists (memantine), which help manage symptoms but do not target amyloid plaques directly.

What other types of research exist?

Promising novel alternatives to Donanemab for Alzheimer's Disease patients in 2024 include: 1) Lecanemab and Aducanumab, which are other antibodies targeting amyloid-beta plaques. 2) Tau protein targeting therapies such as anti-tau antibodies. 3) Anti-inflammatory agents like ALZT-OP1. 4) Neuroprotective strategies including BACE inhibitors and gamma-secretase modulators. These alternatives offer different mechanisms of action and are in various stages of clinical development.

Summary

This trial is testing donanemab, a medication aimed at helping people with Alzheimer's Disease by removing harmful protein clumps from their brains. Donanemab has shown promise in reducing these harmful proteins in Alzheimer's disease.

Who is the study for?

This trial is for people aged 65-80 who are at risk of Alzheimer's but don't yet have it. Participants must be able to get an MRI and do cognitive tests, not be in another study, and have a family history of Alzheimer's or early signs of amyloid and tau pathology.

What is being tested?

The trial is testing Donanemab against a placebo to see if it can prevent the onset of Alzheimer's Disease in individuals who show early signs but do not yet have symptoms. The safety and effectiveness will be evaluated.

What are the potential side effects?

While specific side effects for Donanemab aren't listed here, similar drugs may cause reactions at the injection site, flu-like symptoms, headache, dizziness, nausea or allergic responses.

Other Research

The most common treatments for Alzheimer's Disease (AD) often target amyloid-beta (Aβ) plaques, which are believed to play a critical role in the disease's progression. Donanemab, for example, is an antibody that specifically targets and helps clear Aβ plaques from the brain. This mechanism is crucial because the accumulation of these plaques is associated with neuronal damage and cognitive decline in AD patients. By reducing plaque buildup, treatments like Donanemab aim to slow disease progression and preserve cognitive function. Other treatments may focus on neurotransmitter regulation, such as cholinesterase inhibitors, which increase acetylcholine levels to improve communication between nerve cells. Understanding these mechanisms helps in developing targeted therapies that can more effectively manage or potentially alter the course of Alzheimer's Disease.
