Lenalidomide for Mild Cognitive Impairment
(MCLENA-1 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if lenalidomide (Revlimid) can assist individuals with mild cognitive impairment (MCI) by reducing inflammation in the body and brain, which may contribute to Alzheimer's disease. Participants will take either lenalidomide or a placebo daily for one year, followed by a six-month break to observe changes in their condition. Ideal candidates are adults diagnosed with amnestic MCI, a type of memory loss, who can take oral medication and have someone to assist with study visits. As a Phase 2 trial, this research measures lenalidomide's effectiveness in an initial, smaller group, offering participants a chance to contribute to significant findings in Alzheimer's treatment.
Do I have to stop taking my current medications for this trial?
The trial does not specify if you need to stop taking your current medications. However, you can stay on stable doses of a cholinesterase inhibitor and/or memantine if they have been stable for at least 90 days before the trial and are expected to remain stable during the study.
Is there any evidence suggesting that lenalidomide is likely to be safe for humans?
Research shows that lenalidomide is generally well-tolerated by patients. In earlier studies, individuals taking lenalidomide for mild memory problems mostly experienced mild to moderate side effects. Tiredness and nausea were the most common, but these were usually manageable. These studies reported no serious side effects directly caused by lenalidomide. Additionally, lenalidomide is already approved for other uses, indicating a well-understood safety profile. While this does not guarantee safety for everyone, it offers some reassurance about its overall safety.12345
Why do researchers think this study treatment might be promising for Alzheimer's?
Unlike the standard treatments for mild cognitive impairment, which often include medications like donepezil and others that primarily target neurotransmitter activity, lenalidomide offers a fresh approach. Lenalidomide is unique because it modulates the immune system and has anti-inflammatory properties, which researchers believe could play a crucial role in slowing down cognitive decline. By addressing inflammation, which is increasingly recognized as a factor in neurodegenerative conditions, lenalidomide could offer benefits that current treatments do not. Researchers are excited about this potential dual-action approach, which could lead to more comprehensive management of mild cognitive impairment.
What evidence suggests that lenalidomide might be an effective treatment for Alzheimer's disease?
Research has shown that lenalidomide, which participants in this trial may receive, might help with memory and thinking problems by reducing inflammation linked to Alzheimer's disease. Studies have found that lenalidomide can improve overall brain function in some patients. This improvement relates to changes in certain proteins in the brain fluid associated with inflammation. Simply put, lenalidomide appears to work by lowering inflammation, which is believed to contribute to brain changes in Alzheimer's. These findings suggest that lenalidomide could be a promising treatment for mild memory and thinking issues.12367

Are You a Good Fit for This Trial?
This trial is for men and women aged 50-89 with amnestic MCI, a type of memory loss. Participants need an MMSE score of 22-28, stable health conditions, and must not be at risk of pregnancy. They should have no severe diseases or recent psychiatric disorders that could affect dementia.Inclusion Criteria
