Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | MDS-UPRDS Part III ULE score in the OFF-medication (unilateral treatment) | 3 Months | Between-group difference (Active Group 1 vs. Control Group 1) in the treatment effect (point change) in the MDS-UPRDS Part III ULE score in the OFF-medication state from Baseline to 3 month. This assessment will be performed by a Movement Disorders neurologist blinded to patient study group allocation. |
| Primary | MDS-UPRDS Part III ULE score in the OFF-medication (bilateral treatment) | 3 Months | Between-group difference (Active Group 2 vs. Control Group 2) in the treatment effect (point change) in the MDS-UPRDS Part III ULE score in the OFF-medication state from Baseline to 3 month. This assessment will be performed by a Movement Disorders neurologist blinded to patient study group allocation. |
| Secondary | MDS-UPDRS III Total score in the OFF-medication state | 1 Month, 3 Months, 6 Months, 12 Months | Between-group comparison (Active Group 1 vs Control Group 1) of the treatment effect at Month 3 following Treatment 1 (unilateral) and within-group comparison (Active Group 1) of the treatment effect at all study visits (Month 1, 3 and 6) following Treatment 1 compared to baseline.
