ProMIS Neurosciences Inc., a clinical-stage biotechnology company focused on the generation and development of antibody therapeutics targeting toxic misfolded proteins in neurodegenerative diseases such as Alzheimer’s disease, amyotrophic lateral sclerosis and multiple system atrophy, announced financial results for the fiscal year ended December 31, 2023 and provided a corporate update.
Top-line data from first-in-human Phase 1a clinical trial of PMN310 as a treatment for Alzheimer’s disease on track for mid-2024
CAMBRIDGE, Massachusetts and TORONTO, Ontario, April 01, 2024 (GLOBE NEWSWIRE) -- ProMIS Neurosciences Inc. (Nasdaq: PMN), a clinical-stage biotechnology company focused on the generation and development of antibody therapeutics targeting toxic misfolded proteins in neurodegenerative diseases such as Alzheimer’s disease (AD), amyotrophic lateral sclerosis (ALS) and multiple system atrophy (MSA), today announced financial results for the fiscal year ended December 31, 2023 and provided a corporate update.
“I am pleased to have taken the helm of ProMIS at the beginning of 2024 and am proud of the meaningful progress the team has made to date as ProMIS made the transition to a clinical development company. Importantly, we are nearing the initial read out from our first-in-human studies of our lead product candidate, PMN310, as a potential treatment for AD,” stated Neil Warma, Interim Chief Executive Officer of ProMIS Neurosciences.
“As previously noted, we are nearing completion of the Phase 1a single ascending dose (SAD) clinical trial of PMN310 in AD and remain on track to report top-line data midyear, which will include safety data and PMN310 exposure levels in blood and cerebrospinal fluid (CSF). Moving forward, our goal is to advance PMN310 into a Phase 1b multiple ascending dose (MAD) study in AD patients, which could provide the first proof-of-concept data demonstrating that PMN310 has the potential to positively benefit patients with AD. This is a very exciting opportunity for both ProMIS and the AD patients we aim to serve. In addition, it may have the potential to lead the way for us to advance our differentiated platform in other neurodegenerative diseases, such as ALS, MSA and Parkinson’s disease,” stated Mr. Warma.
“We are diligently identifying ways to explore the potential application of our differentiated platform while not distracting our focus from our lead development program, PMN310, and our tight control on cash management. Specific to our pipeline candidates, we have and will continue to publish and present key data as each progresses and remain excited about the early data generated across a number of neurodegenerative diseases. We look forward to the ongoing development of our novel antibody therapies and to achieving a number of potentially value-creating milestones throughout the balance of the year.”
Recent Highlights
Alzheimer’s Disease Program (PMN310)
PMN310, ProMIS’ lead compound, is a humanized IgG1 antibody directed against toxic amyloid beta oligomers (AβO) that are believed to be a major driver of AD.
- ProMIS dosed the first participants in a first-in-human Phase 1a clinical trial of PMN310 as a potential treatment for AD in November 2023 (Study NCT06105528). The Phase 1a clinical trial is a double-blind, placebo-controlled, single ascending dose study of the safety, tolerability, and pharmacokinetics of PMN310 infusions in up to five cohorts of eight healthy volunteers. PMN310 exposure levels in blood and cerebrospinal fluid (CSF) will be evaluated as well as safety.
- The Company expects to report top-line data from the Phase 1a portion of the study in mid-2024, which will include safety data and exposure levels of antibodies in blood and CSF.
Discovery Programs
ProMIS continues to advance its amyloid beta vaccine program in AD based on its oligomer target epitope(s).
- In January 2024, ProMIS announced the selection of a lead vaccine candidate, PMN400, against multiple synucleinopathies including MSA, Parkinson’s disease and Lewy Body Dementia.
- Using a proprietary computational platform, ProMIS identified potential conformational epitopes (misfolded portions) unique to toxic alpha-synuclein involved in synucleinopathies. Formulations of several of these epitopes were tested in mouse vaccination studies leading to PMN400’s selection as a lead vaccine candidate for testing in mouse models replicating cognitive and motor deficits of human disease.
- In December 2023, ProMIS reported data identifying Receptor for Activated C-Kinase 1 (RACK1) as a novel misfolded protein target for the potential treatment of ALS and frontotemporal lobar degeneration (FTLD), which data were published in Acta Neuropathologica Communications.
Corporate
- In January 2024, the Company announced the appointment of Neil Warma as the interim Chief Executive Officer. Mr. Warma is a seasoned biotechnology executive with more than 25 years of leadership experience. Mr. Warma has served on the Company’s Board of Directors for the past two years and remains as a director.
- In March 2024, ProMIS added key U.S. and international patent allowances to further protect the Company’s monoclonal antibody therapeutic for the treatment of AD.
Full Year 2023 Financial Highlights
- Cash and cash equivalents were $12.6 million as of December 31, 2023, compared to $5.9 million as of December 31, 2022. During the third quarter of 2023, the Company raised $20.4 million in gross proceeds from a private investment in public equity financing, less $2.7 million of issuance costs.
- Research and development expenses were $7.9 million for the fiscal year ended December 31, 2023, compared to $16.1 million for the same period in 2022. The decrease was primarily attributable to a decrease in direct and external research and development expenses as the Company focused on advancing its lead program, PMN310, which entered the clinic in November 2023.
- General and administrative expenses modestly decreased to $6.4 million for the year ended December 31, 2023, compared to $7.3 million for the same period in 2022.
- Net loss was $13.2 million for the full year ended December 31, 2023, compared to a net loss of $18.1 million for full year in 2022.
