Outcome Measures

Primary Outcomes (1)

  • Change From Baseline to Week 12 in the Non-Motor Symptom Scale (NMSS) Total Score

    The NMSS measures the frequency and severity of a range of non-motor symptoms in Parkinson's Disease. It consists of 30 questions grouped into 9 domains: cardiovascular, sleep/fatigue, mood/cognition, perceptual problems/hallucinations, attention/memory, gastro-intestinal tract, urinary, sexual function, and miscellaneous (pain, taste/smell, weight change, excessive sweating). Severity is rated on a scale from 0 (none) to 3 (severe) and frequency is rated on a scale from 1 (rarely) to 4 (very frequent). Item scores are calculated as the product of severity and frequency; the total score is obtained by summing the item scores. The NMSS total score ranges from 0 to 360 with a lower score indicating fewer symptoms; a negative change from baseline indicates improvement in symptoms.

Study Arms (1)

Levodopa-Carbidopa Intestinal Gel

EXPERIMENTAL

Participants had the PEG-J tube placement procedure performed on Study Day 1 and, at the discretion of the investigator, began initiation and titration of LCIG infusion. Dosing was determined individually. The starting total daily dose of LCIG was based solely on the daily dose of the oral levodopa taken immediately prior to Study Day 1 and was adjusted to obtain the optimal clinical response for the individual participant. Participants received treatment for up to 60 weeks; participants who completed their Week 60 visit before LCIG was commercially available had the option to extend their LCIG therapy, if in the opinion of the investigator, the participant would benefit from continued LCIG treatment.

Drug: Levodopa-Carbidopa Intestinal GelProcedure: Percutaneous Endoscopic Gastrostomy with Jejunal Extension (PEG-J)Drug: Levodopa-carbidopa Immediate Release (LC-IR) Tablets

Interventions

Levodopa-carbidopa intestinal gel (LCIG) for upper-intestinal infusion is a suspension of levodopa (20 mg/mL) and carbidopa monohydrate (5 mg/mL) in an aqueous gel, administered continuously by a portable pump via a percutaneous endoscopic gastrojejunostomy (PEG-J) tube. The rate of LCIG infusion was expected to be within the range of 1 to 10 mL/hour (20 to 200 mg of levodopa/hour) in most instances over a period of 16 consecutive hours.

Also known as: Duopa, Carbidopa-levodopa enteral suspension (CLES)
Levodopa-Carbidopa Intestinal Gel

After LCIG initiation, participants could take prescribed oral levodopa-carbidopa immediate or continuous release (i.e., oral LC prescribed by the investigator) for nighttime use.

Eligibility Criteria

Age30 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject must have a diagnosis of idiopathic Parkinson's disease (PD) according to the United Kingdom Parkinson's Disease Society (UKPDS) Brain Bank Criteria
  • Demonstrate persistent motor fluctuations in spite of individually optimized treatment
  • Subject must experience a minimum of 3 hours "Off" time

You may not qualify if:

  • Subject's PD diagnosis is unclear or there is a suspicion that the subject has a Parkinsonian syndrome such as secondary Parkinsonism (e.g., caused by drugs, toxins, infectious agents, vascular disease, trauma, brain neoplasm), Parkinson-plus syndrome (e.g., Multiple System Atrophy, Progressive Supranuclear Palsy, Diffuse Lewy Body Disease, Corticobasilar Degeneration), or other neurodegenerative disease that might mimic the symptoms of PD.
  • Subject has undergone neurosurgery for the treatment of Parkinson's disease
  • Subject for whom the placement of a PEG-J tube for LCIG treatment is contraindicated or is considered a high risk for the PEG-J procedure according to the gastroenterology evaluation (e.g., pathological changes of the gastric wall, inability to bring the gastric wall and abdominal wall together, blood coagulation disorders, peritonitis, acute pancreatitis, paralytic ileus).
