Study Arms:
- Duodopa Naïve (Type: EXPERIMENTAL): Duodopa-naïve participants titrated to receive Duodopa (levodopa/carbidopa intestinal gel) adjusted to an optimal clinical response for each participant, using the portable CADD Legacy Duodopa pump (CE 0473). Treatment is composed of 3 individually adjusted doses: the morning bolus dose (usually 5-10 mL \[100-200 mg levodopa\]); the continuous maintenance dose (usually 2-6 mL/hour \[40-120 mg levodopa/hour\]); and extra bolus doses, adjusted individually.
- Duodopa Non-naïve < 2 Years (Type: EXPERIMENTAL): Duodopa non-naïve participants treated with Duodopa for \< 2 years receive Duodopa (levodopa/carbidopa intestinal gel) adjusted to an optimal clinical response for each participant, using the portable CADD Legacy Duodopa pump (CE 0473). Treatment is composed of 3 individually adjusted doses: the morning bolus dose (usually 5-10 mL \[100-200 mg levodopa\]); the continuous maintenance dose (usually 2-6 mL/hour \[40-120 mg levodopa/hour\]); and extra bolus doses, adjusted individually.
- Duodopa Non-naïve ≥ 2 years (Type: EXPERIMENTAL): Duodopa non-naïve participants treated with Duodopa for ≥ 2 years receive Duodopa (levodopa/carbidopa intestinal gel) adjusted to an optimal clinical response for each participant, using the portable CADD Legacy Duodopa pump (CE 0473). Treatment is composed of 3 individually adjusted doses: the morning bolus dose (usually 5-10 mL \[100-200 mg levodopa\]); the continuous maintenance dose (usually 2-6 mL/hour \[40-120 mg levodopa/hour\]); and extra bolus doses, adjusted individually.

Based on this trial design, predict the completion outcome and termination type (if applicable).
