Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or female ≥ 18 years of age.
• Clinical diagnosis of Idiopathic PD, consistent with UK Brain Bank Criteria (excluding the "more than one affected relative" criterion).
• Clinically meaningful response to Levodopa (L-Dopa) with well-defined "OFF" episodes, as determined by the Investigator.
• Receiving APOKYN® of ≤ 5 mg per dose for at least 4 weeks before the Screening Visit.
• Receiving stable doses of L-Dopa/carbidopa (immediate or sustained release) administered at least 4 times per day OR Rytary™ administered 3 times per day, for at least 4 weeks before the Screening Visit. Adjunctive PD medication regimens must be maintained at a stable dose for at least 4 weeks prior to the Screening Visit with the exception that MAOB inhibitors must be maintained at a stable level for at least 8 weeks prior to the Screening Visit.
• No planned medication change(s) or surgical intervention anticipated during the course of study.
• Patients must experience a well-defined "OFF" episode in the morning if they do not take their morning PD medications on schedule, and must be willing to delay morning doses on the 3 study dosing days
• Stage III or less on the modified Hoehn and Yahr scale in the "ON" state.
• Mini-Mental State Examination (MMSE) score > 23.
• If female and of childbearing potential, must agree to use one of the following methods of birth control:
• Oral contraceptive;
• Contraceptive patch;
• Barrier (diaphragm, sponge or condom) plus spermicidal preparations;
• Intrauterine contraceptive system;
• Levonorgestrel implant;
• Medroxyprogesterone acetate contraceptive injection;
• Complete abstinence from sexual intercourse;
• Hormonal vaginal contraceptive ring; or
• Surgical sterilization or partner sterile (must have documented proof).
• Male patients must be either surgically sterile, agree to be sexually abstinent or use a barrier method of birth control (e.g., condom) or maintain a monogamous relationship with a person who is not of child-bearing potential from first study drug administration until 30days after final drug administration.
• Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study-related procedures to complete the study.
• Able to understand the consent form, and to provide written informed consent

You may not qualify if…

• Atypical or secondary parkinsonism.
• Previous treatment with any of the following: continuous subcutaneous (s.c.) apomorphine infusion; or Duodopa/Duopa.
• Contraindications to APO-go® or APOKYN® or hypersensitivity to apomorphine hydrochloride or any marcrolide antibiotic or any of the ingredients APO-go® or APOKYN® (notably sodium metabisulfite).
• Female who is pregnant or lactating.
• Participation in a clinical trial within 30 days prior to the Screening Visit.
• Receipt of any investigational (ie, unapproved) medication within 30 days prior to the Screening Visit.
• Any selective 5HT3 antagonists (ie, ondansetron, granisetron, dolasetron, palonosetron, alosetron), dopamine antagonists (excluding quetiapine and clozapine) or dopamine depleting agents within 30 days prior to the Screening Visit.
• Drug or alcohol dependency in the past 12 months.
• History of malignant melanoma.
• Clinically significant medical, surgical, or laboratory abnormality in the opinion of the Investigator.
• Major psychiatric disorder including, but not limited to, dementia, bipolar disorder, psychosis, or any disorder that, in the opinion of the Investigator, requires ongoing treatment that would make study participation unsafe or make treatment compliance difficult.
• History of clinically significant hallucinations during the past 6 months.
• History of clinically significant impulse control disorder(s).
• Dementia that precludes providing informed consent or would interfere with participation in the study.
• Current suicidal ideation within one year prior to the Screening Visit as evidenced by answering "yes" to Questions 4 or 5 on the suicidal ideation portion of the Columbia-Suicide Severity Rating Scale (C-SSRS) or attempted suicide within the last 5 years.
• Donation of blood plasma in the 30 days prior to first dosing.
• Cankers or mouth sores within 30 days prior to the Screening Visit, or other clinically significant oral pathology in the opinion of the Investigator. The Investigator should follow-up with an appropriate specialist on any finding, if indicated, before enrolling a patient into the study.
