Who can join

Age: 30 and older, up to 79. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or female subjects who are between 30 and 79 years old inclusive with a clinical diagnosis of Parkinson's disease as per UK Brain Bank Criteria for two (2) years or less at screening.
• Hoehn and Yahr I or II at screening.
• Subjects who are newly diagnosed \& currently not on any Parkinson's disease medication (or) subjects who are on stable doses for at least 4 weeks prior to screening on Amantadine or anticholinergics for treatment of Parkinson's disease
• Note: Subjects that had anti-parkinsonian medication (including levodopa, dopamine agonists, entacapone and monoamine oxidase-B inhibitors) discontinued at least 60 days prior to screening, e.g., for intolerance, may be considered eligible if all other eligibility requirements are met.
• Women of child-bearing potential should use reliable contraception. Acceptable methods of contraception include: surgical sterilization (e.g. bilateral tubal ligation), hormonal contraception (implantable, patch, and oral), and double-barrier methods (condom, diaphragm and spermicide are each considered a barrier). Women of child-bearing potential are defined as women physiologically capable of becoming pregnant, UNLESS they meet the following criteria:
• (1)Post-menopausal: 12 months of natural (spontaneous) amenorrhea or 6 months of spontaneous amenorrhea with serum Follicle Stimulating Hormone (FSH) levels > 40mIU/m, OR; (2)6 weeks post surgical bilateral oophorectomy with or without hysterectomy
• If a male and heterosexually active with a female of childbearing potential, the subject must agree to use a double barrier method of birth control (or must have been surgically sterilized) and to not donate sperm during the study.
• Without clinically significant abnormalities in physical exam, neurological exam and laboratory assessments (urine/blood routine, biochemical tests and ECG) which would exclude the subject from the study in the opinion of the Investigator. For Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) the screening levels should be ≤ 2 times upper limit normal
• Subject is capable of providing informed consent and is willing to sign the ICF prior to study Screening and agrees to comply with the study protocol requirements.

You may not qualify if…

• Subject has an atypical parkinsonian syndrome or secondary parkinsonism (e.g., due to drugs, metabolic neurogenetic disorders, encephalitis, cerebrovascular disease or degenerative disease).
• Subjects with history of neurosurgical intervention for Parkinson's disease.
• Subjects who meet the DSM-V criteria at screening for bipolar disorder, major depressive disorder, psychotic disorders, or any other comorbid mental disorders that in the opinion of the Investigator may interfere with study conduct and results interpretation.
• Subjects with clinical diagnosis of dementia (MMSE score <24) as determined by the investigator using Mini-Mental State Examination (MMSE).
• Female subjects who are pregnant or breast feeding.
• Initiation of any anti-parkinsonian medication (including levodopa, dopamine agonists, entacapone and monoamine oxidase-B inhibitors) for the duration of the trial.
• Initiation of Amantadine or anticholinergics for newly diagnosed subjects or change in the dosage of Amantadine or anticholinergics during the trial for subjects who were on stable doses for 4 weeks prior to screening.
• Subjects who used investigational drugs or devices within 60 days prior to screening or investigational biologics within the last 6 months prior to screening.
• Subjects with a clinically significant or surgical condition, including major surgeries within 28 days prior to enrollment
