Real-World Study of Foslevodopa/Foscarbidopa to Assess Quality of Life Outcomes in Adult Participants Earlier Within Advanced Parkinson Disease

To join this study, your doctor must have already decided that Foslevodopa/Foscarbidopa is the right treatment for you, based on the approved guidelines for the medicine. You need to be an adult between 18 and 80 years old and have Parkinson's disease that responds to levodopa, another common Parkinson's medication. Also, you should have been diagnosed with Parkinson's less than 10 years ago, and experienced changes in your symptoms (like 'on' and 'off' times) for no more than three years. You also need to be willing to fill out questionnaires on a tablet.

However, you can't join if you have certain health conditions mentioned in the medicine's safety information, or if you've already had other advanced treatments for Parkinson's, like deep brain stimulation or other continuous pumps. If you have severe memory problems (a specific score on a memory test) or are already in another research study, you also won't be able to take part. Also, if you have severe skin problems or can't understand the questions well, you might not be suitable.

If you decide to take part, you'll continue to receive the Foslevodopa/Foscarbidopa medicine exactly as your doctor prescribes it. This means you'll be using the subcutaneous infusion (a continuous drip under the skin) in your everyday life. There won't be any extra tests or examinations because of the study. Instead, the main part of your involvement will be filling out several questionnaires. Your caregivers might also be asked to complete some questionnaires. These questionnaires will ask about your movement, your symptoms, and how you're feeling overall, helping us understand your quality of life. You'll use an electronic device, like a tablet, to fill these out. We will follow your progress for up to six months in total.
