ProMIS Neurosciences Reports Top-Line Data From The First Four Cohorts Of Its First-In-Human Phase 1a Clinical Trial Of PMN310 In Healthy Volunteers For Alzheimer's Disease Patients; Topline Results Demonstrated A Favorable Safety Profile And Tolerability Across Four Ascending Dose Levels

Topline results demonstrated a favorable safety profile and tolerability across four ascending dose levels in healthy volunteers and showed dose dependent levels of PMN310 antibody in Cerebrospinal fluid (CSF) suggestive of its potential for target engagement in Alzheimer's disease patients

CAMBRIDGE, Massachusetts and TORONTO, Ontario, July 26, 2024 (GLOBE NEWSWIRE) -- ProMIS Neurosciences, Inc. (NASDAQ:PMN), a biotechnology company focused on the generation and development of antibody therapeutics targeting toxic misfolded proteins in neurodegenerative diseases such as Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS) and multiple system atrophy (MSA), today announced positive top-line data from the first four cohorts of its first-in-human Phase 1a clinical trial of PMN310 in healthy volunteers.

The Phase 1a clinical data, which has been collected and analyzed from the first four of five cohorts, indicated that PMN310 demonstrated a favorable safety profile, was well tolerated and, importantly, crossed the blood brain barrier in healthy volunteers, in a dose dependent manner and at concentrations that suggest sufficient target engagement in the planned follow-on clinical trial in Alzheimer's patients.
