InMed Pharmaceuticals Announces Favorable Behavioral Outcomes with INM-901 in Long-Term Preclinical Alzheimer's Disease Study, Confirming Previous Short-Term Pilot Study Data

In This Article:

  • Results confirm improvements in cognitive function, memory and locomotor activity

  • Achieved statistical significance in certain behavioral assessments

  • Additional molecular analyses ongoing to elucidate INM-901 mechanisms of action

Vancouver, British Columbia--(Newsfile Corp. - July 30, 2024) - InMed Pharmaceuticals Inc. (NASDAQ: INM) ("InMed" or the "Company"), a pharmaceutical company focused on developing a pipeline of proprietary small molecule drug candidates for diseases with high unmet medical needs, today announced positive results from initial data sets from a long-term (7 months of dosing) in vivo preclinical Alzheimer's Disease ("AD") study of INM-901 which confirms previously reported findings from a short-term (3 months of dosing) pilot study, as disclosed in the Company's prior press release dated April 4, 2024.

Similar to the short-term pilot study, this long-term dosing study was conducted using the 5xFAD amyloidosis model with extended dosing duration and increased sample size as compared to the short-term study. This long-term study had four groupings:

  1. Untreated disease-free group;

  2. INM-901-treated disease-free group;

  3. Placebo-treated Alzheimer's Disease (amyloidosis) group; and

  4. INM-901-treated Alzheimer's Disease (amyloidosis) groups with two dosing levels.

It is important to note that disease severity increases with advancing age in this preclinical amyloidosis model such that groups in the long-term study had more advanced AD than those in the previous short-term pilot study.

The study included an assessment of several behavioral criteria across the four study groupings:

  • Novel Object Recognition Test evaluating cognitive function and memory;

  • Open Field Test evaluating general locomotor activity level;

  • Elevated and Zero Maze Tests measuring anxiety-related behavior;

  • Barnes Maze Test measuring spatial learning and memory; and

  • Acoustic Startle Test measuring sound awareness.

All assessments of the INM-901-treated AD groups showed a positive trend towards behaviour similar to the untreated disease-free group, with most assessments demonstrating a clear dose response. Furthermore, INM-901-treated AD groups achieved a statistically significant improvement in certain behavior criteria in comparison to the placebo-treated AD groups. These results not only supported but in several instances improved upon the prior short-term pilot study outcomes.

Dr. Eric Hsu, InMed's Senior Vice President of Preclinical Research and Development, stated; "We are highly encouraged by the initial data sets from this long-term dosing study, which support the previously observed improvements in behavioral outcomes seen in our initial short-term preclinical Alzheimer's proof-of-concept study. INM-901 continues to demonstrate potential by targeting multiple biological pathways linked to Alzheimer's Disease and may have potential to address the critical need for effective treatments."
