A Study to Assess the Safety and Efficacy of the of the Gastric-retentive AP-CD/LD in Advanced Parkinson's Patients

Phase 3
Conditions
Parkinson's Disease
Interventions
Drug: Sinemet®
Drug: Accordion Pill™ Carbidopa/Levodopa
Drug: Placebo- Sinemet
Drug: Placebo -AP-CD/LD
Registration Number
NCT02605434
Lead Sponsor
Intec Pharma Ltd.
Brief Summary

The purpose of this study is to determine whether the gastric retentive Accordion Pill™ Carbidopa/Levodopa (AP-CD/LD) is more effective than the commercially available immediate release Carbidopa/Levodopa in reducing motor fluctuations such as "off time" in advanced Parkinson's Disease patients.

Detailed Description

A multi-center, global, randomized, double-blind, double-dummy, active-controlled, parallel-group study in adult subjects with fluctuating PD. The study will have 2 open label Titration periods of 6 weeks each prior to the double blind Maintenance period. In the open label periods all patients will be stabilized on the active comparator Sinemet® and then on AP-CD/LD. The double blind Maintenance period will be 13 weeks long.

  2. Able and willing to give written (signed and dated) informed consent and adhere to visit schedule and available to complete the study

  3. Men or women 30 years of age and higher at initial screening assessment. (For the 100 subjects who enter the Gastroscopy sub study, the age limits are 30-80 years of age, inclusive, at initial screening assessment)

  4. Diagnosed with Parkinson's disease, consistent with UK brain bank criteria

  5. Has a good response to Levodopa and is taking at least 4 doses of a Levodopa containing medication (or 3 doses of Rytary) per day during waking hours (not including nighttime long acting levodopa) at a stable dose for at least 28 days prior to initial screening assessment

  6. Other Anti-PD treatment (such as dopamine agonists, selective MAO-B inhibitors, anticholinergic agents or Amantadine) are permitted if stable for at least 28 days prior to study entry and provided they are not anticipated to be changed during the course of the study

  7. Total LD immediate release daily dose of 400 mg to 1300 mg or equivalent prior to initial screening assessment. Specifically for Rytary, doses up to 1755 mg daily are acceptable.

  8. Able to complete a Hauser Home Diary and can tell the difference between "On" and "Off" time

    1. Achieved at least 75% diary concordance with an approved site rater in a 4-hour training session including at least one "Off time" assessment
    2. Returned a valid 2-day practice diary after training has been completed.
  9. At least 2.5 hours "Off time" per day during waking hours on Screening 2-day Practice Hauser Home Diary (morning akinesia should be incorporated into the total "Off time" assessment).

  10. Other than PD, the subject is in satisfactory health, as assessed by physical examination and screening tests. No clinically significant medical, psychiatric or laboratory abnormality that could compromise safety or interfere with study procedures in the opinion of either the investigator or the Enrollment Approval Committee/Sponsor.
