Additional funding will be required to complete clinical trials and operate the business. Management believes current cash and cash equivalents are sufficient to fund operating expenses and capital expenditure requirements for at least the next twelve months from the date of issuance of these consolidated financial statements, and efforts to obtain additional funds are ongoing. The new IFRS 18 accounting standard, effective January 1, 2027, is being assessed for its impact on financial statement presentation.

Management Comments

• "Our mission is to develop therapeutic drugs designed to treat neurogenerative diseases, currently focusing on Parkinsonian and other movement disorders."
• "The fact that we achieved statistical significance on the key clinical endpoint, Modified Unified MSA Rating Scale Part 1 (UMSARS Part 1), is extremely meaningful because it assesses the functional areas affected in MSA and it is the endpoint needed to support drug approval by the FDA."
• "These outcomes are potentially promising as stabilization of MSA symptoms is unexpected in this patient population."
• "Management is continuing its efforts to obtain additional funds so that we can meet our obligations and sustain operations."

Industry Context

The biotechnology and pharmaceutical industries are characterized by rapid technological change and intense competition from major pharmaceutical companies, biotechnology firms, universities, and research institutions, many of which possess greater resources and experience.
