Keywords: Idiopathic Parkinson's Disease Lewy Body Parkinson's Disease Paralysis Agitans Primary Parkinsonism
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 630
Healthy volunteers: no

Brief summary:
To evaluate the safety and efficacy of IPX203 (carbidopa and levodopa) extended-release capsules (IPX203 ER CD-LD) in comparison to immediate release (IR) CD-LD in the treatment of CD-LD-experienced participants with Parkinson's disease (PD) who have motor fluctuations.

Detailed description:
This was a multicenter, randomized, double-blind, double-dummy, active-controlled, parallel-group study. The study consisted of a 3-week, open-label IR CD-LD dose adjustment period; a 4-week, open-label period for conversion to IPX203; followed by a 13-week double-blind treatment period with participants randomized in a 1:1 ratio, stratified by center, to receive either IPX203 (with matching IR CD-LD placebo) or IR CD-LD (with matching IPX203 placebo).

Arms:
arm 1: Participants started on the same dose as the pre-study dosing regimen of IR CD-LD and then received dose adjusted IR CD-LD tablets daily orally, for a period of 3 weeks. If the participant was taking controlled release carbidopa-levodopa (CR CD-LD), the CR CD-LD was discontinued and substituted with a 1:1 milligram-equivalent dose of IR CD-LD. arm 2: Participants received extended release (ER) CD-LD (IPX203) capsules orally, every 6 - 12 hours for a period of 4 weeks at a dose based on their most frequent stable dose of IR CD-LD in dose adjustment period. Participant with most frequent stable dose of 25-100 milligrams (mg) IR CD-LD received 70 - 280 mg IPX203 thrice daily (TID); \>25-100 - 37.5-150 mg IR CD-LD received 105-420 mg IPX203 TID; \>37.5-150 - 50-200 mg IR CD-LD received 140-560 mg IPX203 TID; \>50 - 200 mg IR CD-LD received 175-700 mg IPX203 TID. Participants who received a daily total dose of less than 125-500 mg IR CD-LD in dose adjustment received IPX203 every 12 hours. After initial dose conversion from IR CD-LD to IPX203 as per above mentioned dose conversion schedule, the dose of IPX203 could be further adjusted during the 4 week dose conversion period. arm 3: Participants received IPX203 capsules orally, every 6 - 12 hours for 13 weeks at a stable dose established at the end of dose conversion period along with placebo matched to IR CD-LD. arm 4: Participants received IR CD-LD tablets daily orally, for 13 weeks at a stable dose established at the end of dose adjustment period along with placebo matched to IPX203.

Interventions: intervention 1: IR CD-LD intervention 2: IPX203 ER CD-LD intervention 3: Placebo Matching IPX203 intervention 4: Placebo Matching IR CD-LD
Intervention descriptions: intervention 1: Active comparator - IR CD-LD intervention 2: Investigational formulation - ER CD-LD intervention 3: Double dummy placebo capsules intervention 4: Double dummy placebo tablets
