First in-human clinical trial results show feasibility of new Parkinson cell therapy

First in-human clinical trial results show feasibility of new Parkinson cell therapy Craig Brierley Thu, 07/09/2026 - 13:00 In Parkinson’s disease, patients lose nerve cells in the brain that produce dopamine, leading to symptoms such as slowness of movement, stiffness, gait disturbance and tremor. The current treatments are medications that replace the lost dopamine, but over time these medications often become less effective and cause side effects. The trial – known as STEM-PD – is led by Lund University, Sweden, in collaboration with the University of Cambridge.
