Rhea-AI Summary

ProMIS Neurosciences (ARFXF) applauds Biogen's FDA approval of aducanumab for Alzheimer’s, marking a pivotal moment in Alzheimer's treatment. This approval reinforces momentum in the field, with ProMIS anticipating increased interest in next-generation therapies such as its PMN310 antibody, which selectively targets toxic amyloid-beta oligomers. PMN310 uniquely avoids non-toxic forms, potentially enhancing safety and efficacy compared to other therapies. ProMIS aims to lead in developing disease-modifying treatments for Alzheimer's and other neurodegenerative diseases.

Positive
  • FDA approval of aducanumab boosts confidence in Alzheimer's therapies.
  • ProMIS' PMN310 antibody targets toxic oligomers with high selectivity, potentially offering better efficacy and safety.
Negative
  • None.

Approval of aducanumab offers real hope for patients and fuels development of next-generation therapies with more selective binding for toxic species of amyloid beta

TORONTO and CAMBRIDGE, Mass., June 08, 2021 (GLOBE NEWSWIRE) -- ProMIS Neurosciences, Inc. (TSX: PMN) (OTCQB: ARFXF), a biotechnology company focused on the discovery and development of antibody therapeutics targeting toxic oligomers implicated in the development of neurodegenerative diseases, today congratulates Biogen on the recent FDA approval of its monoclonal antibody therapeutic, aducanumab, for the treatment of Alzheimer’s disease (AD).       

After two years of setbacks in the AD field, 2021 has seen significant progress and reason for optimism in the AD community. Biogen’s June 7th FDA approval of aducanumab as well as recent positive clinical trial data from Cassava (simufilam) and Lilly (donanemab) offer further potential positive momentum for AD patients.

“The approval of aducanumab marks the availability of the first disease-modifying therapy for AD, the sixth leading cause of death in the United States,” stated ProMIS Executive Chairman Eugene Williams. “We congratulate Biogen on this important development for AD patients and their caregivers. We now anticipate accelerated interest and support for the development of next generation therapies, such as ProMIS’ PMN310 lead antibody therapeutic for AD. Using our proprietary discovery platform we were able to create an antibody that selectively targets the toxic oligomers of amyloid-beta (A) and avoids undesirable binding to non-toxic forms of amyloid. We believe this high degree of selectivity by PMN310 may offer significant differentiation in terms of efficacy and safety compared to the currently less selective antibody products.”

PMN310, is a humanized monoclonal antibody that binds with high affinity and selectivity to toxic oligomers of A, a recognized root cause of AD. Importantly, PMN310 does not appreciably bind to A plaque or vascular deposits of A thereby reducing the likelihood of brain swelling (edema), a dose-limiting side effect observed with non-selective therapeutic antibodies that interact with A plaque.
