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 three months ended March 31, 2022.
“In Q1 of 2022 we have continued the significant progress of late 2021, advancing and expanding our portfolio of differentiated therapeutic product candidates in diseases such as Alzheimer’s disease (AD), ALS, and schizophrenia,” said Gene Williams, ProMIS’ Chairman and CEO. “Our lead program PMN310 for Alzheimer’s continues rapid progress to an IND filing and clinical trials. Our unique technology platform also enables us to make therapeutic vaccine “versions” of our antibody therapies, and we announced excellent progress toward an anti-amyloid therapeutic vaccine for Alzheimer’s at a major international conference. We added to the senior management team a very strong and experienced Chief Medical Officer in Larry Altsteil, MD. 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.”
ProMIS lead program PMN310: Potential Next Generation Therapy for AD
PMN310, an antibody therapy selective for toxic amyloid-beta oligomers in AD, is our lead product candidate. In the first quarter of 2022, the Company made significant progress on the program elements.
Producer cell line development has been completed. We have manufactured material to be used in Good Laboratory Practice (GLP) toxicology studies and are on track for producing current Good Manufacturing Practice (cGMP) material for use in the initial clinical trials of PMN310, if allowed to proceed. We have completed pilot toxicology, pharmacokinetics (PK) and tissue cross reactivity (TCR) studies and secured slots for the formal GLP studies that are required for an investigational new drug (IND) application. Development of assays to measure drug levels in nonhuman primates was completed in the second quarter of 2022 and development of assays to measure drug levels in human studies are expected to be completed in the third quarter of 2022. Vendors have been contracted to perform these assays in support of our GLP studies.
In addition, we have initiated formulation development with two vendors, with the goal of developing a high concentration formulation that can support subcutaneous dosing as a future step to improve overall convenience and patient compliance. We expect completion of formulation work in the second quarter of 2022.
Expenditures for PMN310 in the three months ended March 31, 2022 were approximately $1.4 million, not including allocations of senior management time.
ALS Portfolio, including TAR-DNA binding protein 43 (TDP-43)
Dr. Gene Yeo’s laboratory at the University of California San Diego showed that an intrabody version of PMN267 delivered inside cells via a gene therapy vector significantly reduced the amount of TDP-43 aggregates in human motor neurons derived from ALS patients, the cell type predominantly affected in ALS. In an aggressive mouse model of ALS/FTD conducted at a contract research organization, testing of PMN267 as an injectable antibody treatment also produced encouraging trends for protection against disability. These results are in line with reports indicating that antibodies with effector function can be taken up inside neurons and trigger degradation of their target, in this case toxic TDP-43 aggregates. The evidence to date supports potential use of PMN267 both as an intrabody or as a conventional antibody acting inside neurons as well as outside neurons to stop the cell-to-cell propagation of toxic TDP-43 aggregates.
ProMIS’ capability to create highly selective antibodies is most critical for intracellular activity since physiologically important TDP-43 is active inside the neuron and should be avoided by the intrabodies to reduce the possibility of harmful side effects. 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). ProMIS’ preclinical data implicating RACK1 in ALS were presented as a poster at the American Academy of Neurology in Seattle, entitled “RACK1 Knockdown Alleviates TDP-43-Associated Global Translational Suppression in vitro and Neurodegeneration in vivo.” 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 three months ending March 31, 2022, our total expenditure for the ALS portfolio was $145,000, not including allocations of senior management time.
Other key projects
In the amyloid vaccine program, the results of our initial studies with the University of Saskatchewan Vaccine and Infectious Disease Organization (VIDO) were presented at the International AD/PD conference in Barcelona, Spain in a talk entitled “Optimizing vaccine design for Alzheimer’s disease: Selective targeting of computationally-derived conformational B cell epitopes of soluble amyloid-beta toxic oligomers.” Building on the data obtained, additional mouse studies are ongoing with VIDO with the goal of developing an optimized AD vaccine, conjugating our peptide antigens to a carrier protein in formulation with an adjuvant. A vaccination study in a mouse model of AD has been initiated.
David Wishart, our Chief Physics Officer, and his team are pursuing multiple novel targets including DISC1 involved in the pathogenesis of schizophrenia. ASO approaches to target pathogenic DISC1 are also being explored with Dr. Michelle Hastings.
