Safinamide is a medication used to treat Parkinson’s disease. It works by helping to maintain dopamine levels in the brain and reducing abnormal brain signaling that causes movement problems. In this trial, researchers are specifically studying how this medication might help reduce pain that people with Parkinson’s disease experience, particularly in patients who have fluctuating motor symptoms (times when their movement symptoms get better or worse throughout the day).

Parkinson’s Disease with Motor Fluctuations – A progressive neurological condition characterized by periods when medication’s effectiveness varies throughout the day, causing alternating periods of good mobility and poor movement control. During these fluctuations, patients experience changes between periods of being “on,” when medications are working well and symptoms are controlled, and being “off,” when medications are not working effectively and symptoms become more pronounced. The motor fluctuations typically include tremors, muscle stiffness, slow movement, and difficulties with balance and coordination. These symptoms can vary in intensity throughout the day, making daily activities unpredictable. The fluctuations often become more noticeable as the disease progresses and can significantly impact the person’s ability to perform regular activities.
