Arm Intervention/treatment
Active Comparator: Optimized Medical Treatment
12 Week Period

Dose levels of prescribed antiparkinsonian medications will be individually optimized to their maximum therapeutic effect.

Experimental: ABT-SLV187
12 Week Period
Drug: ABT-SLV187

Other Name: Carbidopa-Levodopa Enteral Suspension LCIG

Primary Outcome Measures :
  1. Unified Dyskinesia Rating Scale (UDysRS) Total Score [ Time Frame: 12 weeks ]
    The UDysRS is used to evaluate on-dyskinesia in Parkinson's disease and the impact of on-dyskinesia on experiences of daily living.

Secondary Outcome Measures :
  1. Unified Parkinson's Disease Rating Scale (UPDRS) Part III Score (Motor Examination) [ Time Frame: 12 weeks ]
    The UPDRS is a rating tool to follow the longitudinal course of Parkinson's disease.

  2. OFF time [ Time Frame: 12 weeks ]
    OFF time as measured by Parkinson's disease Diary, which the subject and/or caregiver uses to record Parkinsonian symptoms.

  3. Clinical Global Impression of Change (CGI-C) Score [ Time Frame: 12 weeks ]
    The CGI-C is a rating scale for assessing Global Improvement or Change.

  4. ON time without troublesome dyskinesia [ Time Frame: 12 weeks ]
    "ON" time without troublesome dyskinesia as measured by the Parkinson's disease Diary, which the subject and/or caregiver uses to record Parkinsonian symptoms.

  5. Parkinson's Disease Questionaire-8 (PDQ-8) Summary Index [ Time Frame: 12 weeks ]
    The PDQ-8 is a self-administered questionnaire that measures aspects of health that are relevant to subjects with PD that may not be included in general health status questionnaires.

  6. Unified Parkinson's Disease Rating Scale (UPDRS) Part II Score (Activities of Daily Living) [ Time Frame: 12 weeks ]
    The UPDRS is a rating tool to follow the longitudinal course of Parkinson's disease.

Layout table for eligibility information
Ages Eligible for Study:   30 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Participants must have a diagnosis of idiopathic Parkinson's disease (PD )according to the United Kingdom Parkinson's Disease Society (UKPDS) Brain Bank Criteria
  • Participants with advanced levodopa-responsive PD and persistent motor fluctuations who have not been controlled with optimized medical treatment (OMT: the maximum therapeutic effect obtained with pharmacological antiparkinsonian therapies when no further improvement is expected with regard to any additional manipulations of levodopa and/or other antiparkinsonian medication based on the Investigator's clinical judgment)
  • Unified Dyskinesia Rating Scale (UDysRs) Total score ≥ 30 at Visit 3

Exclusion Criteria:

  • Patient(s) treated with LCIG previously
  • Patient'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) or other neurodegenerative disease that might mimic the symptoms of PD
  • Patient(s) has undergone neurosurgery for the treatment of Parkinson's disease.
  • Patient(s) has contraindications to levodopa (e.g. narrow angle glaucoma, malignant melanoma)
  • Patient(s) experiencing clinically significant sleep attacks or clinically significant impulsive behavior (e.g. pathological gambling, hypersexuality) at any point during the three months prior to the Screening evaluation as judged by the Principal Investigator
