Business Overview and Company History
ProMIS Neurosciences Inc. (NASDAQ:PMN) is a clinical-stage biotechnology company at the forefront of developing innovative antibody therapeutics targeting toxic misfolded proteins implicated in the pathogenesis of neurodegenerative diseases. The company's pioneering platform technology enables the selective targeting of disease-specific misfolded proteins, a key differentiator in its approach to tackling some of the most challenging neurological disorders.
ProMIS Neurosciences was incorporated on January 23, 2004 under the Canada Business Corporations Act (CBCA). In July 2023, the company continued its existence from a corporation incorporated under the CBCA into the Province of Ontario under the Business Corporations Act Ontario (OBCA), a move approved by shareholders at the 2023 Annual Meeting. The company has a wholly-owned U.S. subsidiary, ProMIS Neurosciences US Inc., incorporated in Delaware in 2016, though this entity has had no material activity or financial impact on the consolidated financial statements.
Since its inception, ProMIS has dedicated itself to developing its proprietary technology platform to generate a portfolio of antibody therapies, therapeutic vaccines, and other antibody-based treatments targeting toxic misfolded proteins in neurodegenerative diseases. The company's focus areas include Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA), which it believes share a common biological cause in the form of misfolded proteins that become toxic and kill neurons.
ProMIS' technology platform combines protein biology, physics, and supercomputing to enable the selective targeting of the toxic misfolded protein species driving neurodegenerative diseases, while avoiding interference with the essential functions of properly folded proteins. This approach is a key differentiator for the company, as it seeks to develop therapeutics that can effectively treat the underlying pathology without causing unintended consequences.
The company's lead product candidate is PMN310, a monoclonal antibody designed to treat Alzheimer's disease by selectively targeting toxic, misfolded oligomers of amyloid-beta. PMN267, targeting misfolded TDP-43 in ALS, and PMN442, targeting misfolded alpha-synuclein in synucleinopathies like MSA and Parkinson's disease, are two other key programs in ProMIS' pipeline.
Throughout its history, ProMIS has faced challenges typical of a development-stage company without product revenue. The company has primarily financed its operations through public and private placements of common shares and warrants, as well as convertible debt. These ongoing financing efforts reflect the significant investments required to advance its pipeline of antibody product candidates.
In 2023, the company made significant progress on its lead program PMN310, initiating a first-in-human Phase 1a clinical trial in November of that year. The study, a double-blind single ascending dose (SAD) trial in 40 healthy volunteers, completed enrollment of the 5 SAD cohorts (2.5, 5, 10, 20, 40 mg/kg) by May 2024. Topline data from the first 4 cohorts were released in July 2024, and results on all 5 cohorts were presented at the Clinical Trials on Alzheimer's Disease (CTAD) conference in October 2024.
Across the dosing range, plasma concentrations of PMN310 were linearly dose proportional, as were total exposure (AUC0-∞) and maximum concentration (Cmax). Importantly, cerebrospinal fluid (CSF) concentrations of PMN310 were linearly dose-dependent and 100-600 times the estimated CSF molar concentration of Aβ oligomers. The plasma half-life (t1/2) was approximately 17.5 days, and the CSF t1/2 was approximately 27 days, indicating that monthly dosing may provide levels of PMN310 adequate for target engagement in AD patients.
Building on these positive Phase 1a results, ProMIS plans to initiate a Phase 1b proof of concept trial in AD patients in the fourth quarter of 2024. This randomized, placebo-controlled, double-blind clinical trial is expected to enroll 100 patients and will assess not only critical biomarkers and incidence of ARIA, but also extend for 12 months to enable measurement of important clinical cognition endpoints.
In July 2024, ProMIS announced a private placement financing that raised gross proceeds of $30.3 million upfront, with the potential for an additional $92.4 million if warrants granted in the transaction are exercised. The net proceeds from this financing are expected to support the company's development of PMN310, including the upcoming Phase 1b trial in AD patients, as well as for general corporate purposes.
Financial Situation and Liquidity
As of September 30, 2024, ProMIS reported cash of $21.5 million. However, the company had an operating loss of $4.4 million and $10.8 million for the three and nine months ended September 30, 2024, respectively, and an accumulated deficit of $90.4 million as of that date. Management has stated that these conditions raise substantial doubt about the company's ability to continue as a going concern within the next twelve months from the date of filing the latest quarterly report.
To address its liquidity needs, ProMIS will continue to seek additional funding through public and private financings, debt financings, collaboration agreements, strategic alliances, and licensing agreements. While the company has been successful in raising capital in the past, there is no assurance of success in obtaining such additional financing on terms acceptable to ProMIS. Failure to secure the necessary funding could force the company to delay, reduce, or eliminate its research and development programs and product portfolio expansion or commercialization efforts, which could adversely affect its future business prospects and ability to continue operations.
For the nine months ended September 30, 2024, ProMIS reported the following financial metrics: - Net loss: $10.8 million - Total operating expenses: $10.8 million - Research and development expenses: $6.3 million - General and administrative expenses: $4.5 million - Operating cash flow: ($18.5) million - Free cash flow: ($18.5) million
The company does not have any revenue as it is still in the clinical development stage for its product candidates. Its operating expenses are primarily driven by research and development activities, as well as general and administrative costs to support the business.
For the most recent quarter ended September 30, 2024, ProMIS reported: - Revenue: $0 - Net income: $9.28 million - Operating cash flow: ($6.67) million - Free cash flow: ($6.67) million
The company's current ratio and quick ratio as of September 30, 2024, were both 9.30, indicating a strong short-term liquidity position. However, the company does not disclose information on available credit lines or other credit facilities.
It's important to note that ProMIS does not disclose performance by geographic markets, likely due to its small cap status and current focus on the US market. Additionally, there is no information provided about any scandals, short seller reports, or CEO departures.
In July 2024, ProMIS completed a private placement, raising $30.33 million in gross proceeds before deducting $2.65 million in placement agent fees and other expenses. The company plans to use the proceeds to advance the clinical development of PMN310, as well as for working capital and other general corporate purposes.
Product Portfolio and Development Pipeline
ProMIS Neurosciences' product portfolio and development pipeline are focused on three main areas:
1. Alzheimer's Disease (AD) Portfolio The company's lead product candidate is PMN310, a monoclonal antibody designed to selectively target toxic, misfolded oligomers of amyloid-beta. In 2024, ProMIS made significant progress on the PMN310 program. The company initiated a first-in-human Phase 1a clinical trial in November 2023, with enrollment of the 5 single ascending dose cohorts completed in May 2024. Topline data from the first 4 cohorts were released in July 2024, and results on all 5 cohorts were presented at the Clinical Trials on Alzheimer's Disease (CTAD) conference in October 2024. The data showed that PMN310 crossed the blood-brain barrier in a dose-dependent manner, with pharmacokinetics suggesting that monthly dosing could provide adequate target engagement in AD patients. Based on these positive results, ProMIS plans to initiate a Phase 1b proof-of-concept trial in AD patients in the fourth quarter of 2024.
2. Amyotrophic Lateral Sclerosis (ALS) Portfolio ProMIS's second lead product candidate is PMN267, which has been humanized in a human IgG1 framework and is ready to progress to IND-enabling studies, subject to available resources. PMN267 has been shown in preclinical studies to selectively recognize misfolded, cytoplasmic TDP-43 aggregates, which are believed to play an important role in the development of ALS.
3. Multiple System Atrophy (MSA) Program ProMIS has selected PMN442, a novel monoclonal antibody, as a lead candidate for MSA based on its selective binding and protective activity against pathogenic forms of alpha-synuclein. PMN442 has been humanized in a human IgG1 framework and is also ready to progress to IND-enabling studies, subject to availability of sufficient resources. This candidate has shown robust binding to pathogenic a-syn oligomers and seeding fibrils in preclinical studies, with negligible binding to a-syn monomers and physiologic tetramers, positioning it as a potential treatment for synucleinopathies such as MSA and Parkinson's disease.
