Anti-Bin1 antibodies: treatment for Alzheimer's disease

Lead investigators: Sunil Thomas, PhD, James Mullin, PhD, George C. Prendergast, PhD

Unmet need

The incidence of late-onset Alzheimer’s disease (LOAD) in developed countries with aging populations is skyrocketing. In the U.S. alone, about 5.8 million have Alzheimer’s disease (AD), and it is the sixth leading cause of death, according to the Alzheimer’s Association. Medical advances paralleling aging demographics in developed countries have created an unprecedented need for strategies to prevent and treat dementia, most especially LOAD.


Human genetics studies have identified Bin1 as second only to ApoE as a risk factor for LOAD. Neurology studies indicate that Bin1 binds and influences the turnover of tau as a likely mechanism in promoting LOAD risk. LIMR scientists developed a cell-penetrating Bin1 antibody that appears to promote tau turnover to inhibit its expression and cellular deposition. This therapeutic technology based on novel MOA may offer a route to attenuate AD driven by tau deposition.

The global market for effective therapeutics for AD is estimated to grow from $3.64B in 2017 to $5.66B in 2024, according to Zion Market Research,

Unique attributes

The scaffold and signaling molecule Bin1 modifies stress and inflammatory responses of cells under stress. A cell-permeable anti-Bin1 antibody — developed by LIMR scientists as a strategy to blunt its pathogenic function in inflammatory bowel disease—was found to exert anti-tau effects in cell culture and animals when examined. With the emergence of elevated Bin1 expression as a risk factor in LOAD development, this experimental therapeutic may be effective. Indeed, given emerging evidence of gut-brain interactions in the development of neurodegenerative diseases, including LOAD, this therapeutic intersection may be relevant.

A survival benefit has been observed in early tests of anti-Bin1 administration in a tauopathy-based mouse model of AD. Accordingly, anti-Bin1 may offer a novel tractable target to limit the development or progression of AD pathophysiology in patients.

Clinical applications

The LIMR mAb offers potential uses to treat AD and other tauopathy-based pathologies.
