ProMIS Neurosciences Inc PMN

ProMIS Neurosciences Inc. is a clinical-stage biotechnology company. It is focused on generating and developing antibody therapeutics selectively targeting toxic misfolded proteins in neurodegenerative diseases such as Alzheimer’s disease (AD), amyotrophic lateral sclerosis (ALS) and multiple system atrophy (MSA). Its proprietary target discovery engine applies a thermodynamic, computational discovery platform-ProMIS and Collective Coordinates-to predict novel targets known as Disease Specific Epitopes on the molecular surface of misfolded proteins. Using this approach, the Company is developing novel antibody therapeutics for AD, ALS and MSA. Its product candidates are PMN310, PMN267, and PMN442. The PMN310 is a monoclonal antibody designed to treat AD by selectively targeting toxic, misfolded oligomers of amyloid-beta. PMN267 product candidate targeting ALS. PMN442 is a drug candidate being developed for MSA designed to selectively target and protect against pathogenic a-syn species.

Figures 4 and 5 show the selectivity story.

Figure 4 is binding to target in presence of monomer (no plaque presence)

Figure 5 assesses binding to plaque, which is thought to be the driver of ARIA-E.  

Drugs that bind strongly to plaque tend to have poor ARIA-E results.  Acumen's ACU193 does appear to be an improvement, but not as good as PMN with respect to plaque binding.

It will be interesting to see clinical data from PRX coming out.  Based on the PMN theories, it will likely be less effective due to monomer competition and cause ARIA-E due to plaque binding. 

These are just my personal interpretations of the data.




My point is that PMN310 shows its selective binding to oligomers, not monomers pre-clinical still needs to be proven in humans. We're not there yet. And even if it does will it be more beneficial to fight an AD brain? Just playing with the devil's advocate.
