| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Feasibility of future large-scale double-blind randomized controlled trial (RCT) | From enrollment to the end of study at 5 weeks. | The primary objective is to investigate the feasibility of conducting a future large-scale double-blind randomized controlled trial (RCT) assessing the effect on orthostatic hypotension (OH) of different dosages of Carbidopa (20, 50 or 100 mg), for a constant Levodopa dose (200 mg) through: * Recruitment rate: Mean number of patients informed per month during the recruitment period, % of patients wiling to participate to the study among the informed patients, % of patients eligible among the informed patients * Adherence rate:% of patients completing the study intervention period among randomized patients * Retention rate:% of patients showing up at the last follow-up visit among patients who have completed the study intervention period, % of drop-outs among randomized patients at last follow-up visit * Data completion rate of the therapeutic effect measures: % of patients with analysable OH data at week 1, 2 and 3. |
