- Change in neurotoxicity burden [ Time Frame: 6 months ]Estimate the change from baseline to six months in neurotoxicity burden measured by a composite Patient Global Impression of Improvement score
- Change in mean Fahn-Tolosa-Marin (FTM) score [ Time Frame: 6 months ]Estimate the change in the mean FTM score among patients with self-reported tremors from baseline to six months.
