Keywords: PARKINSON'S DISEASE, extension study
Type: Drug study, Phase 3
6 Participants
Parkinson's disease (or PD) is a disease that slowly damages the motor system. The motor system is the part of the central nervous system that is involved with movement. When a person gets Parkinson's disease, the cells that make dopamine in a part of the brain die. Dopamine cells send information to other cells which makes us do the actions we do.

This study will test the long-term safety, tolerability and effectiveness of the experimental Accordion Pill™ Carbidopa/Levodopa (AP-CD/LD). It will be used in patients with fluctuating Parkinson’s disease (PD) who completed the main study (IN 11 004). We will study how AP-CD/LD affects the symptoms of Parkinson’s disease long-term. We will evaluate participant responses on questionnaires, rating scales and examinations. Patients will also have the opportunity for extended treatment with AP-CD/LD. This will occur after they have successfully completed the main study IN 11 004.

The name of the experimental drug that will take in this study is Accordion Pill™ Carbidopa/Levodopa. This is an oral drug (capsule) for the treatment of PD symptoms (motor and non-motor fluctuations). The Accordion Pill™ Carbidopa/Levodopa contains two drugs: levodopa combined with carbidopa. The Accordion Pill™ Carbidopa/Levodopa was developed by Intec Pharma Ltd. to extend the duration of the Levodopa activity and its effectiveness by keeping the drug in the stomach for a longer time. In this form, this product is known as the “experimental drug”. Experimental means that the drug has not yet been approved by the Food and Drug Administration (FDA) or the European Medicines Agency (EMA).

  3. Has a good response to Levodopa in the opinion of the investigator
  4. Subjects able and willing to give written (signed and dated) informed consent to participate in the study

Exclusion criteria:

  1. Participation in another clinical trial other than IN 11 004 and receipt of an investigational medication other than that administered in the context of IN 11 004 within 28 days prior to the planned start of treatment
  2. Previous or planned neurosurgical or Duodopa treatment for Parkinson's Disease (e.g., procedures including ablation or deep brain stimulation)
  3. Non-selective monoamine oxidase (MAO) inhibitors within 28 days prior to Baseline Visit or planned administration during study participation
  4. If, in the opinion of the Investigator, subject should not participate in the study
