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.

The Efficacy dataset included all participants who received at least 1 infusion of LCIG study drug and had a baseline and LCIG Treatment Period observation for at least one efficacy or health outcome measure.

Use of healthcare resources was assessed by the investigator using the Health Resource Utilization Questionnaire (HRUQ), a questionnaire developed by the Sponsor regarding the use of healthcare resources due to the participant's Parkinson's disease. The Week 4 version of the questionnaire addressed the following questions during the first four weeks after the PEG-J procedure:

1. Has the subject had a visit to an emergency room?
2. Has the subject had a visit to an urgent care?
3. Has the subject had an outpatient visit to a neurologist?
4. Has the subject had an outpatient visit to a gastroenterologist, surgeon, or interventional radiologist?
5. Has the subject had an outpatient visit to a primary care physician?
6. Has the subject called the nursing support line?
7. Has the subject called a physician?

The Safety dataset included all participants who underwent the PEG-J placement procedure

Adverse events (AEs) related to treatment are those the investigator determined as having a reasonable possibility being related to study drug based on evidence to suggest a causal relationship between the study drug and the adverse event.

A severe AE was defined as an adverse event that caused considerable interference with the participant's usual activities and might be incapacitating or life-threatening.

Serious AEs were defined as those that were life-threatening or resulted in death, hospitalization or prolongation of hospitalization, a congenital anomaly, persistent or significant disability/incapacity, or important medical events requiring medical or surgical intervention to prevent a serious outcome.

The Safety dataset

Use of healthcare resources was assessed by the investigator using the Health Resource Utilization Questionnaire (HRUQ), a questionnaire developed by the Sponsor regarding the use of healthcare resources due to the participant's Parkinson's disease. The standard version of the questionnaire addressed the following questions over the last 3 months:

1. Has the subject had a visit to an emergency room?
2. Has the subject had an outpatient visit to any of the following healthcare providers?
3. Has the subject been visited in his or her place of residence by a health care professional?
4. Has the subject received assistance from either of the following for their Parkinson's disease in their home?
5. Has the subject needed to contact either of the following for immediate assistance related to their Parkinson's disease?
6. Have family members or friends had to miss any paid work due to the subject's Parkinson's disease?
7. Has the subject fallen during the past month?

The Parkinson's Disease Diary was completed by the participant for 3 consecutive days prior to each visit for the full 24 hours of each day. Participants recorded whether they had been "On," "Off," or "Asleep" and the severity of their dyskinesias (troublesome or not troublesome) for each 30-minute period during their normal waking time and upon awakening from time asleep.

"Off" time was defined as time when medication has worn off and was no longer providing benefit with regard to mobility, slowness, and stiffness.

Parkinson's Disease Diary times were normalized to a 16-hour waking time to account for variation in participants' sleep time. Normalized PD Diary times at a given visit were calculated as the average normalized time from the PD Diary for the 3 days prior to the visit.

The PD Diary was completed by the participant for 3 consecutive days prior to each visit. Participants recorded whether they had been "On," "Off," or "Asleep" and the severity of their dyskinesias (troublesome or not troublesome) for each 30-minute period during their normal waking time and upon awakening from sleep.

"On" was defined as time when medication was providing benefit with regard to mobility, slowness, and stiffness. "On" time without troublesome dyskinesia is a composite of "On" time without dyskinesia (involuntary twisting, turning movements which are an effect of medication) plus "On" time with non-troublesome dyskinesia (dyskinesia that does not interfere with function or cause meaningful discomfort).

PD Diary times were normalized to a 16-hour waking time to account for variation in participants' sleep time. Normalized PD Diary times at a given visit were calculated as the average normalized time from the PD Diary for the 3 days prior to the visit.

CANTAB is a computer-based test of the participant's ability to retain spatial information and to manipulate remembered items in working memory. The Spatial Working Memory module requires that subjects find a blue token in a series of displayed boxes and use these to fill up an empty column, while not returning to boxes where a blue token has been previously found. The between errors score is the number of times the participant revisited a box in which a token was previously found; errors are calculated for 4-, 6-, and 8-box trials. Higher numbers indicate poorer performance.
