Firm Creates Novel Intrabodies for ALS and Other Neurodegenerative Diseases
News Update

ProMIS Neurosciences reported it has generated novel intrabodies that are highly selective for misfolded forms of TAR DNA-binding protein 43 implicated in several neurologic disorders.

In a news release, ProMIS Neurosciences Inc. (PMN:TSX; ARFXF:OTCQB) announced that "it has generated intrabodies highly selective for misfolded forms of TAR DNA-binding protein 43 (TDP-43) implicated in amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and several other neurologic disorders." The company further indicated that "early data support the use of these intrabodies within gene therapy vectors based on their selectivity and ability to promote degradation of toxic species of TDP-43 while preserving normal forms of the protein."

The firm explained that intrabodies are antibody therapies designed to block toxic proteins inside a cell in order to accelerate their degradation and prevent them from spreading to healthy cells. ProMIS stated that it has generated several highly selective intrabodies that bind to toxic TDP-43 protein and that early data represents a promising first step in the development of effective and safe therapies for ALS, FTD and other TDP-43-driven disorders.

The company's Co-Founder and Chief Science Officer Dr. Neil Cashman commented, "The results obtained with ProMIS' TDP-43 intrabodies once again show the strength and versatility of our drug discovery and development platform, which identifies novel binding targets on complex protein structures and allows us to create antibody and now intrabody candidates that target those specific sites...We can apply our platform to the biology of any misfolded protein to develop antibody and intrabody candidates that are highly selective for only toxic species so as to preserve normal protein function."

"We've used our platform to produce novel antibody candidates for several neurodegenerative diseases, including Parkinson's and Alzheimer's. We're currently also helping the COVID-19 effort by using our platform to identify unique binding sites on the protein halo of the virus which can be used for accurate testing of virus-reactive antibodies in the blood," Dr. Cashman added.

ProMIS Neurosciences Inc. is a biotechnology company headquartered in Toronto. The firm states that its core technology gives it the capability to methodically predict the site and shape of new targets known as disease specific epitopes (DSEs) on molecular surfaces of proteins. The company noted that "in neurodegenerative diseases such as Alzheimer's, ALS and Parkinson's, the DSEs are misfolded regions on otherwise normal proteins; however, in infectious disease settings, DSEs represent peptide antigens that can be used as an essential component to create accurate and sensitive serological assays to detect the presence of antibodies that arise in response to a specific infection, such as COVID-19."
