Description of intervention(s) / exposure
Treatment: Drugs - Levodopa-carbidopa intestinal gel
Treatment: Devices - PEG tube
Treatment: Devices - J-tube

Experimental: Levodopa-Carbidopa Intestinal Gel (LCIG) - All participants were to receive LCIG, via the NJ tube during the nasojejunal (NJ) Test Period and delivered to the proximal small intestine via percutaneous endoscopic gastrostomy - with jejunal extension tube (PEG-J) during the Post-PEG-J Long-Term Treatment Period. The starting dose was individually determined based on the daily dose of oral levodopa prior to study enrollment.

The infusion dose was individually optimized for each participant on the basis of response and potential adverse events. During the Post-PEG-J Long-Term Treatment Period, LCIG was expected to be infused continuously over approximately 16 hours daily with a rate of infusion ranging from 1 to 10 mL/hour (20 to 200 mg of levodopa/hour), in most instances.


Treatment: Drugs: Levodopa-carbidopa intestinal gel
Infusion should be kept within a range of 0.5-10 mL/hour (10-200 mg levodopa/hour) and is usually 2-6 mL/hour (40-120 mg levodopa/hour).

Treatment: Devices: PEG tube
percutaneous endoscopic gastrostomy tube
