ProMIS Neurosciences Inc. reported significant financial developments in its latest 10-Q filing for the quarter ending June 30, 2026. The company recorded a net loss of $11.7 million for the three months ended June 30, 2026, compared to a loss of $10.1 million for the same period in 2025. For the six months ended June 30, 2026, the net loss increased to $20.0 million from $17.5 million in the prior year. Total operating expenses for the second quarter were $12.3 million, up from $10.2 million in the previous year, driven primarily by increased research and development costs associated with its lead product candidate, PMN310.
The company experienced a substantial increase in cash reserves, with total current assets rising to $56.7 million as of June 30, 2026, compared to $9.2 million at the end of 2025. This increase was largely due to a successful private placement in January 2026, which generated net proceeds of $70.1 million from the sale of common shares and warrants. As a result, ProMIS's accumulated deficit reached $150.4 million by the end of the second quarter, reflecting ongoing investments in its research and development pipeline.
Operationally, ProMIS is advancing its clinical programs, particularly PMN310, which targets toxic amyloid-beta oligomers in Alzheimer's disease. The company completed its Phase 1a trial and is currently conducting a Phase 1b trial, with enrollment completed in December 2025. Interim results from this trial have shown a favorable safety profile, with no serious adverse events reported. The company is also developing additional candidates, including PMN267 for ALS and PMN442 for synucleinopathies, indicating a broadening of its therapeutic focus.
In terms of organizational changes, ProMIS has expanded its employee base, with a notable increase in salaries and benefits contributing to higher general and administrative expenses, which rose to $4.4 million for the six months ended June 30, 2026, compared to $3.4 million in the prior year. The company continues to seek additional funding to support its ongoing clinical trials and operational needs, emphasizing the importance of securing capital to sustain its growth strategy.
Looking ahead, ProMIS anticipates continued operating losses as it invests in the development of its product candidates. The company expects its existing cash reserves, bolstered by recent financing, to be sufficient to cover operational expenses through 2027. However, it acknowledges the need for further funding to support future clinical activities and potential commercialization efforts, highlighting the inherent risks associated with its development pipeline and the broader market conditions.
