During these conferences, Neil Warma, CEO of ProMIS Neurosciences, will discuss the Company’s EpiSelect™ platform and differentiated approach to developing therapeutics for neurodegenerative diseases driven by toxic misfolded proteins, including its lead Alzheimer’s disease (AD) candidate, PMN310.

PMN310 is designed to selectively target toxic amyloid-beta oligomers believed to drive AD pathology while avoiding plaque binding, an approach intended to potentially reduce off-target effects associated with plaque-directed therapies.

ProMIS expects to report blinded 6-month interim data from its fully enrolled PRECISE-AD Phase 1b trial in patients with early AD in early Q3 2026, with 12-month topline data anticipated in early 2027.

Webcast replays of the presentations will be available in the Investors section of the ProMIS Neurosciences website at https://www.promisneurosciences.com/ under “News & Events”.
