Biotech Stresses Need to Target Only Toxic Oligomer in Alzheimer's Therapies
News Update

The company cites the recent discontinuation of other firms' clinical programs as proof.

ProMIS Neurosciences Inc. (PMN:TSX; ARFXF:OTCQB) reiterated in a news release that the global effort to develop Alzheimer's disease-modifying therapies must selectively target, with exact precision, the toxic oligomer form of beta amyloid beta believed to be a root cause of the disorder.

This announcement comes on the heels of other biotech firms having aborted their clinical programs testing potential treatments for Alzheimer's disease. Most recently, Biogen and partner Eisai terminated two phase 3 clinical trials of aducanumab. Earlier in the year, Roche Holdings and partner AC Immune ended their crenezumab program.

ProMIS purported that both drug candidates failed because they were not selective enough in their targeting of amyloid beta. Aducanumab bound primarily to the plaque form whereas crenezumab bound to all amyloid beta forms.

What is required for an Alzheimer's disease therapy, according to ProMIS, is one that precisely targets only the misfolded, toxic form of amyloid beta. ProMIS' lead antibody candidate for Alzheimer's, PMN310, does just that, "offering a potential significant advantage over aducanumab and other less selective antibodies in terms of both efficacy and safety," ProMIS' Chief Medical Officer Dr. James Kupiec said in the release.

"Aducanumab was developed over a decade ago to go after plaque, which we have since learned is the incorrect therapeutic target because plaque is a largely non-toxic form of amyloid beta," Kupiec noted.

"Aducanumab wasted too much limited ammunition on the wrong target, which also led to the dose limiting side effect of brain swelling (edema). Unlike aducanumab, ProMIS’ lead antibody candidate for Alzheimer’s, PMN310, reflects key lessons learned, namely that the toxic oligomer of amyloid beta is a root cause of AD, not plaque. PMN310 is the first antibody to selectively target just the toxic oligomer, a misfolded, toxic form of amyloid beta," Kupiec stated.
