Leede Financial analysts Dr. Douglas Loe and Siew Ching Yeo, in a research report published on October 30, 2024, maintained their Speculative Buy rating on ProMIS Neurosciences Inc. (PMN:TSX; PMN:NCM) with a price target of US$9.50. The report follows ProMIS's presentation of interim Phase I data for PMN310, its Alzheimer's disease (AD) candidate, at the Clinical Trials on Alzheimer's Disease (CTAD) conference.

The analysts highlighted the positive safety and pharmacokinetic (PK) data, stating, "We were encouraged (though not overly surprised) to see that the mAb was well-tolerated at all five test doses ranging from 2.5mg/kg-to-40mg/kg." They added, "PK analysis of all of these patient cohorts in this single-ascending dose (SAD) trial suggests that once-monthly dosing may be sufficient to sustain mAb levels both in plasma and in cerebrospinal fluid over time."

Regarding dosing efficacy, the analysts noted, "Importantly, ProMIS indicated in the Jul/24 update that even at 2.5mg/kg dosing, PMN310 levels in CSF were over 100x higher than predicted to be necessary to bind to all beta-amyloid oligomers that could accumulate in CSF in diseased patients."

The analysts emphasized the significance of recent industry developments, particularly AbbVie's acquisition of Aliada Therapeutics, stating, "AbbVie's tangible interest in Phase I-stage AD assets shows us that ProMIS could itself be attractive to future suitors if/when it can document direct impact on cognitive impairment in diseased patients."

The report highlighted ProMIS's financial position following its recent equity offering, noting that the company raised US$30.3M with multiple layers of warrant coverage tied to development milestones.

Leede Financial's valuation methodology combines multiple approaches. The analysts explained, "We are maintaining our Speculative Buy rating and one-year PT of US$9.50 on PMN, with our valuation still based on NPV (30% discount rate) and multiples of our F2029 EBITDA/fd EPS forecasts."

They added, "By direct comparison to Aliada's US$1.4B value, PMN shares would notionally be valued on a fully-diluted basis at US$17.65/shr."

In conclusion, Leede Financial's maintenance of their Speculative Buy rating and US$9.50 price target reflects confidence in ProMIS's development of PMN310 and its potential in the Alzheimer's disease market. The share price at the time of the report of US$1.03 represents a potential return of approximately 822% to the analysts' target price, highlighting the significant upside potential if the company's clinical development plans prove successful.
