This study will be conducted in 3 parts. A) compare the pharmacokinetics (PK) of a single
dose of AZ-009 with that of a therapeutically-relevant dose of a commercially available
apomorphine injector in healthy volunteers; B) ascending doses of active drug in healthy
volunteers; and C) examine the tolerability, safety, and PK of AZ-009 in subjects with
established Parkinson's disease.
