ProMIS Neurosciences Announces Fiscal Year 2021 Results, The Canadian Business Journal

TORONTO, Ontario and CAMBRIDGE, Massachusetts , March 17, 2022 (GLOBE NEWSWIRE) — ProMIS Neurosciences, Inc. (TSX: PMN) (OTCQB: ARFXF) (“ProMIS” or the “Company”), a biotechnology company focused on the discovery and development of antibody therapeutics targeting misfolded proteins such as toxic oligomers, implicated in the development of neurodegenerative diseases, today announced its operational and financial results for the fiscal year ended December 31, 2021.

“2021 was an excellent year for ProMIS including strong capital formation which enabled us to advance and expand our portfolio of differentiated therapeutic product candidates such as Alzheimer’s disease (AD), ALS, and Schizophrenia,” said Gene Williams, ProMIS’ Chairman and CEO.   “We feel privileged that leading global experts continue to join our Scientific Advisory Board (SAB), accomplished executives are joining our Board of Directors, and that we have been able to supplement our strong management team, and we expect to continue those trends. We were grateful for the strong shareholder support for the resolution necessary to qualify for a potential listing on a major North American stock exchange presuming we meet the required listing standards. While biotechnology markets and specific disease sectors within biotechnology have cyclical ups and downs, we are well positioned to continue making substantive progress in our programs that could allow us to capitalize when markets rebound, as we believe they will.”

PMN310, an antibody selective for toxic oligomers in AD, is ProMIS’ lead product candidate. In the fourth quarter of 2021, the Company made significant progress on the program elements.

Producer cell line development is advancing. The genetic sequence of PMN310 has been transfected into Chinese hamster ovary (CHO) cells, the standard production cells for antibody manufacturing. We have contractually secured manufacturing slots for material to be used in Good Laboratory Practice (GLP) toxicology studies and for current Good Manufacturing Practice (cGMP) material for use in the initial clinical trials of PMN310, if allowed to proceed. In addition, we have contractually secured slots for GLP toxicology studies of various durations in nonhuman primates to support our single ascending dose/multiple ascending dose (SAD/MAD) trials. We have initiated pilot toxicology and pharmacokinetics (PK) studies to provide important information to support our GLP toxicology studies. We expect those PK studies to be completed in the second quarter of 2022. We also have secured slots for pilot and GLP tissue cross reactivity (TCR) studies, which are required for an investigational new drug (IND) application, in addition to GLP toxicology. The pilot TCR study was initiated fourth quarter of 2021 with an expected completion in second quarter 2022. Development of assays to measure drug levels in both nonhuman primate and human studies have been initiated and are expected to complete development in second quarter of 2022. Vendors have been contracted to perform these assays for our GLP studies.

In addition, in March 2022, we announced the results from a study assessing chronic systemic administration of PMN310 in a transgenic mouse model of Alzheimer’s disease, where the cognitive deficit is driven by toxic amyloid-beta oligomers. The results were positive, showing that PMN310 prevented a cognitive deficit as measured by performance in the water maze task.   

Cash expenditures for PMN310 in the six months ended December 31, 2021 were approximately $3.8 million. The largest component of this was a $2.7 million up-front and additional payments to our manufacturing vendor to secure manufacturing slots necessary for the filing of an IND and dosing of patients in our initial clinical trials. In addition, $834,000 of other external expenses and $326,000 was incurred for consulting fees of the program team, not including allocations of senior management time.

ALS Portfolio, including TAR-DNA binding protein 43 (TDP-43)

The top priority for our scientific validation efforts, largely centered in Dr. Neil Cashman’s laboratory at the University of British Columbia (UBC), is the Company’s ALS portfolio. This portfolio includes antibodies targeting misfolded forms of TDP-43, RACK1, and superoxide dismustase 1 (SOD1). TDP-43 is the focus of the PMN267 program. We are conducting both in vitro assays (assessing the impact of the drug on patient-derived motor neuron cell lines) and in vivo assays (mouse model) and expect initial data in the first half of 2022. In addition, we are exploring different therapeutic modalities in our ALS portfolio. We have disclosed data from our proof of concept work exploring “intrabody” versions of TDP-43 antibodies, a research proxy for a vectorized antibody in a gene therapy vector. We believe this therapeutic approach could enhance therapeutic benefit inside the motor neurons where misfolded TDP-43 aggregates are a root cause of disease pathology, leading to toxic misfolding of other proteins including RACK1 and SOD1. ProMIS’ capability to create highly selective antibodies is most critical in this application, since physiologically important TDP-43 is active inside the neuron and should be avoided by the intrabodies in order to reduce the possibility of harmful side effects. Based on the characterization of selected antibodies/intrabodies to date, we have declared PMN267 as our lead product candidate for the treatment of ALS. In addition, with world expert RNA scientist Dr. Michelle Hastings, ProMIS is exploring antisense oligonucleotide (ASO) therapeutic approaches, and with Dr. Justin Yerbury, is exploring protein degradation (PROTACS) approaches in ALS.

While targeting individual misfolded proteins is expected to provide a benefit, we believe an optimal disease modifying therapeutic approach to ALS may require addressing multiple misfolded protein targets (TDP-43, RACK1, and SOD1), with different modalities (antibody, gene therapy vectorized antibody, ASO, PROTAC). We are exploring the scientific interaction between therapies addressing these various targets, and our goal is to identify and develop a portfolio of complementary therapies that alone and/or together may play a significant role in effectively treating disease.

In the six months ended December 31, 2021, our total expenditures for the ALS portfolio were $299,000, not including allocations of senior management time.

Other key projects

In the six months ended December 31, 2021 we made significant progress on other key projects, in addition to our top priorities PMN310 for AD and PMN267 for ALS. We have engaged with a leading global expert in alpha synuclein to collaborate on further in vitro and in vivo validation of our potential therapies targeting alpha synuclein, both as extracellular antibodies and as intrabodies. Based on the characterization of selected antibodies to date, we have declared PMN442 as our lead alpha synuclein product candidate. Data from in vivo testing in mouse disease models are expected in the second half of 2022.

In our amyloid vaccine program, based on successful pilot work, University of Saskatchewan vaccine and infectious disease organization (VIDO) is conducting mouse studies in collaboration with ProMIS for the development of an optimized vaccine against Alzheimer’s disease, conjugating our peptide antigens to a carrier protein in formulation with an adjuvant. David Wishart, our Chief Physics Officer, and his team, are pursuing multiple novel targets including DISC1 involved in the pathogenesis of schizophrenia.

General and Administrative

General and administrative expenses consist of the following:

    Years Ended December 31,          
    2021     2020     Change  
    (in thousands)  
Personnel related (including stock-based compensation)   $ 1,279,197     $ 1,191,967     $ 87,230  
Professional and consulting fees     2,801,237       1,311,427       1,489,810
