Background

Lenalidomide is an anti-cancer drug with pleiotropic anti-inflammatory, anti-angiogenic, and immune stimulatory activities. Sold under the brand name Revlimid, lenalidomide has been used since 2006 to treat multiple myeloma, lymphoma, and myelodysplastic syndromes. The capsules are taken by mouth. In cancer patients, the main side effects are abnormal blood counts and blood clots. Lenalidomide is structurally similar to thalidomide, and as such is considered a teratogen with the potential to cause birth defects and fetal death.

Lenalidomide is being pursued as an alternative to thalidomide, whose development for AD was stopped because of dose-limiting toxicity in elderly patients (Decourt et al., 2017). Both drugs have anti-inflammatory activity, lowering the expression of TNFα, IL-6 and IL-8, and increasing expression of anti-inflammatory cytokines, e.g., IL-10. Both are also claimed to reduce amyloidogenesis by inhibiting BACE1 expression. In cancer patients, both drugs have the potential to induce cognitive impairment, according to published case reports (Argente-Escrig et al., 2018; Morgan et al., 2003; Rollin-Sillaire et al., 2013).

No preclinical data has been published for lenalidomide in AD models. In other models, the drug reportedly blocked α-synuclein toxicity by reducing inflammation (Valera et al., 2017; Valera et al., 2015) and extended survival in ALS mice (Neymotin et al., 2009; Kiaei et al., 2006).

Findings

In July 2020, a Phase 2 trial at Cleveland Clinic Lou Ruvo Brain Health Center in Las Vegas began testing lenalidomide in 30 people with mild cognitive impairment. The MCLENA-1 study is enrolling participants with a clinical diagnosis of amnestic MCI plus low hippocampal volume, or a positive amyloid PET scan, or an ApoE4 allele. Enrollees will receive 10 mg lenalidomide or placebo daily for one year, followed by a six-month washout. The primary outcome is cognition, including ADAS-Cog, ADCS-ADL, CDR-SB, and MMSE scores. Other outcomes are safety, measures of brain amyloid, structural MRI, and blood levels of inflammatory markers. The protocol is published (Decourt et al., 2020). The treatment phase is expected to be completed in September 2023.
