In this study, researchers are testing a new medicine called suvecaltamide for people with Parkinson's Disease (PD) who have moderate to severe tremors. A tremor is when your body shakes without you trying to make it move. This can make everyday tasks harder. The study lasts up to 23 weeks, with 17 weeks of treatment. It is double-blind, meaning neither the doctors nor the participants know who gets suvecaltamide or a placebo (a fake treatment). This helps ensure the results are fair.

Key Points:

• The study has different parts: a 4-week screening, a 5-week dose adjustment, 12-week maintenance, and a 2-week follow-up.
• Participants need stable PD medications for at least 6 weeks before joining the study.
• Women who are pregnant or planning to get pregnant cannot participate.

Before joining, make sure PD medications are stable, and consider the commitment of up to 23 weeks. Participants must not be treatment-naïve, meaning they should have tried PD medication before. Always talk to your doctor to see if this study is right for you.
