Female patients must have a negative pregnancy test at screening and at admission. 3. Patients must have a body mass index (BMI) within the range of 18.5 – 35 kg/m2, where BMI = body weight (kg) / height (m2) at screening. 4.

Exclusion criteria
Exclusion criteria: 1. Previously unable to tolerate ND0612 and/or have experienced intolerable adverse drug reactions associated with its use or serious adverse reaction. 2. Atypical or secondary parkinsonism. 3. Acute psychosis or hallucinations within the past 6 months prior to screening. 4. Any relevant medical, surgical, or psychiatric condition, laboratory value, or concomitant medication which, in the opinion of the Investigator, makes the patient unsuitable for study entry or potentially unable to complete all aspects of the study. 5.

Patients who have previously been enrolled in this study. 12. Patients who do not have suitable veins for multiple venipunctures / cannulation as assessed by the Investigator at the screening visit. 13. Psychiatric, neurological or behavioral disorders that may interfere with the conduct or interpretation of the study, including dementia, or patients who are considered to be violent or at suicidal risk by the Investigator. 14. Presence or history of clinically significant allergy requiring treatment, as judged by the Investigator or serious hypersensitivity to any drug or the formulation excipients. Hay fever is allowed unless it is active. 15.Blood loss of greater than 500 mL within the previous 3 months prior to first dosing. 16. Current use of the dopamine agonist pramipexole within 1 month before Day 1. 17. Intake of domperidone within 2 days before Day 1 or planned to be taken before last PK sampling. 18.

Patients who are taking any of these medications at screening should be converted to an equivalent dose of oral LD/CD IR tablets as detailed in Table 4). 19. Intake of donepezil (Aricept) within 14 days before Day 1. 20. Intake of trihexylphenidyl (benzhexole) within 2 days before Day 1. 21.

| Main Objective: To assess relative bioavailability of levodopa (LD) administered as ND0612, infused subcutaneously (s.c.), with orally co-administered LD/CD (Test) versus LD administered as carbidopa-levodopa enteral suspension (CLES), infused via a permanent percutaneous endoscopic gastrostomy with jejunal tube (PEG-J) or a naso-jejunal tube (Reference).;Secondary Objective: • To assess the safety and tolerability of study treatments. • To assess the pharmacokinetics (PK) of LD and carbidopa (CD) derived from ND0612 plus oral LD/CD or from CLES.;Primary end point(s): For LD: • Cmax and AUC24 the concentrations measured with the following 24-hours periods will be included into the calculation of AUC24: for ND0612 16-hours regimen (Test 1): from start of dosing until 24 hours post start of dosing (06:00 to 06:00); for ND0612 24-hours regimen (Test 2): from start of second low rate period until end of third high rate period (20:00 to 20:00); for CLES regimen: from start of dosing until 24 hours post start of dosing (06:00 to 06:00);Timepoint(s) of evaluation of this end point: For LD: • Cmax and AUC24 the concentrations measured with the following 24-hours periods will be included into the calculation of AUC24: for ND0612 16-hours regimen (Test 1): from start of dosing until 24 hours post start of dosing (06:00 to 06:00); for ND0612 24-hours regimen (Test 2): from start of second low rate period until end of third high rate period (20:00 to 20:00); for CLES regimen: from start of dosing until 24 hours post start of dosing (06:00 to 06:00) | — |

| Secondary end point(s): For LD: • AUC16 (i.e. 6:00-22:00 for CLES and ND0612 16-hours and 6:00-22:00 last day of administration for ND0612 24-hours) • Cavg, (AUCt/t represents the mean concentration within the dosing period) • End points assessing the variability of the concentrations: these endpoints will be assessed both during the expected stable phase as defined in the SAP. For the piecewise approach, the end points are calculated separately for the 2 or 3 hour periods, as defined in the SAP. o Fluctuation Index (FI; ([Cmax-Cmin])/[Cavg]) o Peak to Trough (PtT = Cmax/Cmin) o Swing ([Cmax-Cmin]/[Cmin]) • t1/2 (if data permit) • lambda z (if data permit) • tmax • Ctrough (last planned PK sample in a period) For CD: • Cmax • AUC24 • Ctrough (last planned PK sample in a period) For 3-OMD: • Cmax • AUC24 • Ctrough (last planned PK sample in a period);Timepoint(s) of evaluation of this end point: For LD: • AUC16 (i.e. 6:00-22:00 for CLES and ND0612 16-hours and 6:00-22:00 last day of administration for ND0612 24-hours) • Cavg, (AUCt/t within the dosing period) • End points assessing the variability of the concentrations: these endpoints will be assessed both during the expected stable phase as defined in the SAP. For the piecewise approach, the end points are calculated separately for the 2 or 3 hour periods, as defined in the SAP. • Ctrough (last planned PK sample in a period) For CD: • Cmax • AUC24 • Ctrough (last planned PK sample in a period) For 3-OMD: • Cmax • AUC24 • Ctrough (last planned PK sample in a period) | — |
