Longeveron Inc. (NASDAQ: LGVN) has secured a Canadian intellectual‑property protection for its lead mesenchymal stem cell therapy, laromestrocel, by receiving Patent No. 3043594. The grant, titled “Method of Using Human Mesenchymal Stem Cells to Effect Cellular and Humoral Immunity,” covers the use of laromestrocel for non‑ischemic dilated cardiomyopathy and aging‑related frailty and provides exclusive rights in Canada through 2037.
The patent strengthens Longeveron's position in two high‑need therapeutic areas. Non‑ischemic dilated cardiomyopathy currently has no approved disease‑modifying treatments, while aging‑related frailty lacks effective interventions. By securing Canadian exclusivity, Longeveron can protect its investment in clinical development and potentially negotiate licensing or partnership agreements in the Canadian market.
Despite the positive intellectual‑property news, Longeveron remains in a challenging financial environment. The company reported a 53% decline in revenue for the third quarter of 2025 compared with the same period last year, reflecting broader headwinds in its early‑stage pipeline and limited commercial traction. Management has highlighted that the company’s cash position remains stronger than its debt load, with a current ratio of 2.09, providing some flexibility to fund ongoing research and development activities.
CEO Wa’el Hashad emphasized that the patent is a key milestone in the company’s long‑term commercialization strategy. “Securing Canadian exclusivity for laromestrocel is a critical step that protects our investment and positions us to pursue broader market access,” Hashad said. He added that the company will continue to focus on its most promising programs, particularly hypoplastic left heart syndrome and Alzheimer’s disease, where laromestrocel has received multiple FDA designations such as Orphan Drug, Fast Track, and Regenerative Medicine Advanced Therapy.
The patent grant does not immediately translate into revenue, but it enhances Longeveron’s competitive moat and may improve its attractiveness to potential partners or investors. The company’s current financial challenges underscore the importance of this IP milestone as a strategic lever to secure future funding and commercial opportunities while it navigates a difficult development landscape.
The Canadian patent, coupled with Longeveron's ongoing clinical progress and strategic focus on high‑potential indications, represents a significant step forward for the company’s long‑term growth prospects, even as it continues to address short‑term financial pressures.
