Study to Evaluate the Efficacy and Safety of Staccato Apomorphine (AZ-009) in Patients With Parkinson's Disease Experiencing OFF Episodes

Study Overview
=================
Brief Summary
-----------------
This study will be conducted with In-clinic visits and treatment at home for each patient with established Parkinson's disease (PD) experiencing daily OFF episodes.

Detailed Description
-----------------
The purpose of this protocol is to establish the safety, tolerability, and efficacy of AZ-009 compared to placebo in patients with established PD experiencing daily OFF episodes. Patients between the ages of 30 and 85 with a clinical diagnosis of established PD who experience motor fluctuation and have recognizable OFF periods are eligible for participation in this study. The patients will be classified as Modified Hoehn & Yahr stage II-IV in the ON state and have clear, self-described daily motor fluctuations while on oral l-dopa or Carbidopa (with or without adjunctive PD therapy). This study will be conducted in approximately 50 patients, with up to 8 Open-Label titration in-clinic visits with treatment at home between visits. This is followed by Double Blind which includes a 13 day treatment at home period, and an in-clinic visit and an End of Study/Early Termination visit for each patient with established Parkinson's disease (PD) experiencing daily OFF episodes.

Any clinically significant or unstable medical or psychiatric condition, as determined by the PI, based on a medical evaluation including history, physical examination, vital signs, electrocardiograms (ECGs), and laboratory tests assessed at the screening visit and prior to the first dose of study drug that could compromise the participant's safety or interfere with the completion of this protocol. A patient with a non-clinically significant abnormality or laboratory parameters outside the reference range may continue with the approval of the Investigator. Subjects with a prolonged QT interval corrected for heart rate according to Fridericia's formula (QTcF) of >450 ms for male and >470 ms for female at screening or directly prior to first dosing, or a history of long QT syndrome. Also subjects with a PR interval > 220 msec or QRS duration > 120 msec at screening. Currently taking, or may need treatment with, nitroglycerine Any documented active or suspected or history of malignancy within 5 years prior to Visit 1, except appropriately treated basal cell carcinoma. Active hallucinations or history of hallucinations in the past 3 months. Any significant medical condition, psychiatric illness, current major uncontrolled depression or bipolar disease, or history of depression that could, in the investigator's opinion, compromise the subject's safety or interfere with the completion of this protocol. Dementia indicated by MMSE <24 at Screening. History of clinically significant central nervous system (e.g., seizures), cardiac, pulmonary (e.g., asthma, COPD), metabolic, renal, hepatic, or gastrointestinal (GI) conditions including gastric bypass or other weight loss surgical procedure; or history of such conditions that, in the opinion of the investigator, may place the subject at an unacceptable risk as a participant in this trial, may interfere with the interpretation of safety and/or tolerability data obtained in the trial, or may interfere with the absorption, distribution, metabolism, or excretion of the study drugs. Screening FEV1 < 50% of predicted or FEV1/FVC ratio < 60% in the ON state at Visit 1. Any condition including the presence of laboratory abnormalities, which according to the investigator places the subject at unacceptable risk if he/she were to participate in the study. Aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transferase (GGT), serum creatinine, or total bilirubin > 1.5 x upper limit of normal (ULN) at screening or prior to the first dose of study drug. An exception may be made for suspected Gilbert's syndrome. These laboratory tests may be repeated once, if they are abnormal on first screening, and if there is a medical reason to believe the results may be inaccurate. If the repeat test is within the reference range, the subject may be included only if the investigator considers that the previous finding will not compromise the subject's safety and will not interfere with the interpretation of safety data. Positive blood screen for human immunodeficiency virus (HIV antibody), hepatitis B virus surface antigen, or hepatitis C virus antibody at screening.

Donation of blood, plasma or other blood products or blood collection in excess of 470 mL within 8 weeks prior to dosing. Known sensitivity to any of the study drugs or components thereof, or a history of medication allergy or other allergy that, in the opinion of the investigator, contraindicates study participation. Major surgery within 4 weeks of screening that could interfere with, or for which the treatment might interfere with, the conduct of the study, or that would pose an unacceptable risk to the subject in the opinion of the investigator. Use of 5HT3 antagonists, including antiemetics (e.g., ondansetron, granisetron, dolasetron, palonosetron) and alosetron during the trial. Medications to treat gastroparesis (Antiemetics) or any dopamine antagonist.
