Promising Long-Term Results for a New Parkinson’s Cell Therapy

New 36-month results from an early trial of bemdaneprocel, a cell therapy developed by BlueRock Therapeutics (part of Bayer), show meaningful improvements in movement and daily living abilities for people with Parkinson’s disease. Bemdaneprocel aims to replace the lost dopamine-producing cells in the brain — rather than just treating symptoms — offering a new approach to restoring what Parkinson’s gradually takes away. Meaningful Improvements Over Three Years Participants receiving the higher dose of bemdaneprocel experienced a 17.9-point improvement in their movement scores (MDS-UPDRS Part III) compared with baseline — a change considered clinically meaningful. People on the lower dose also improved, showing a 13.5-point gain, while both groups reported better ability to manage daily activities (Part II scores). Importantly, patients spent more time “ON” — when symptoms are better controlled — and less time “OFF”, when movement is more difficult. These benefits were seen even after the protective immunosuppressive medication was stopped, and no serious side effects related to treatment were reported. Why This Matters For people living with Parkinson’s, current treatments help manage symptoms but cannot yet slow or stop disease progression. Bemdaneprocel represents a potential step toward changing that — using living cells to restore dopamine function at its source. As study investigator Dr. Claire Henchcliffe explains, these findings are early but encouraging: “The initial signals are there, particularly in the higher dose group.” The next phase of testing, called ExPDite-2, will further explore its safety and effectiveness in a larger Phase III trial. Looking Ahead While more research is needed, bemdaneprocel joins a growing field of therapies that aim to move beyond symptom control and toward disease modification — slowing, halting, or even reversing aspects of Parkinson’s. For now, the results offer renewed hope that future treatments may help people live with greater stability, independence, and quality of life.
