Lenalidomide for Mild Cognitive Impairment
(MCLENA-1 Trial)
Trial Summary
What is the purpose of this trial?
Accumulating evidence indicates that inflammation is prominent both in the blood and central nervous system (CNS) of Alzheimer's disease (AD) patients. These data suggest that systemic inflammation plays a crucial role in the cause and effects of AD neuropathology. Capitalizing on the experience from a previous clinical trial with thalidomide, here, the investigators hypothesize that modulating both systemic and CNS inflammation via the pleiotropic immunomodulator lenalidomide is a putative therapeutic intervention for AD if administered at a proper time window during the course of the disease.
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.
What data supports the idea that Lenalidomide for Mild Cognitive Impairment is an effective drug?
The available research shows that Lenalidomide is being tested for its effects on mild cognitive impairment due to Alzheimer's disease. In a study called MCLENA-1, 30 patients with mild cognitive impairment are being treated with Lenalidomide to see if it can improve their thinking skills. The study also looks at safety and how the drug affects the brain. However, the research does not yet provide clear evidence of its effectiveness for this condition, as it is still in the testing phase. Most of the existing data on Lenalidomide is about its use in treating certain types of cancer, not cognitive impairment.12345
What safety data exists for lenalidomide treatment?
Lenalidomide, also known as Revlimid, is primarily used for treating multiple myeloma and myelodysplastic syndromes. Common adverse effects include neutropenia, thrombocytopenia, thromboembolic events, gastrointestinal issues, skin eruptions, atrial fibrillation, and asthenia. There are also reports of lenalidomide-induced arthritis and decreased peripheral blood stem cell yield. In a Phase II trial for mild cognitive impairment due to Alzheimer's, safety and tolerability are being assessed through adverse events, vital signs, clinical biochemistry, and physical and neurological examinations. The trial aims to determine if lenalidomide is safe for Alzheimer's patients and can alter disease progression.12678
