A Study to Assess Pharmacokinetic Profiles of LY03003 and Neupro

Inclusion Criteria:

To participate in the study, subjects must meet all inclusion criteria at screening:

1. Willing and capable of giving informed consent;
2. Between the ages of 18 and 45 years old, inclusive;
3. Healthy, per investigator judgment, based on detailed medical history, clinical laboratory safety tests, vital signs, full physical examination, and ECG;
4. Nonsmoker defined as not having smoked or used any form of tobacco within 6 months before screening;
5. BMI between 18.5 and 30 kg/m2, inclusive, and body weight ≥50 kg at screening;
6. Willing and able to comply with study procedures, adhere to study restriction, and stay at the CRU during in-patient stays required by the protocol;
7. All female subjects (childbearing potential and non-childbearing potential) must have a negative serum pregnancy test result at screening. In addition, female subjects must meet 1 of the following 3 conditions: (i) postmenopausal for at least 12 months without an alternative medical cause, (ii) surgically sterile (hysterectomy, bilateral oophorectomy, bilateral salpingectomy, or bilateral tubal ligation/occlusion) based on subject report, or (iii) if of childbearing potential and heterosexually active, practicing or agree to practice a highly effective method of contraception. Highly effective methods of contraception include an intrauterine device (IUD), intrauterine hormone-releasing system (IUS), and contraceptives (oral, skin patches, or implanted or injectable products) using combined or progestogen-only hormonal contraception associated with inhibition of ovulation. A vasectomized male partner is an acceptable contraception method if the vasectomized partner is the sole sexual partner of the female subject and the vasectomized partner has received medical confirmation of surgical success. Highly effective methods of contraception must be used for at least 21 days prior to study drug dosing, throughout the study, and for a minimum of 1 month after the end of the study to minimize the risk of pregnancy.
8. Sexually active, fertile, male patients must be willing to use acceptable contraception methods throughout the study and for at least 1 month after the end of the study if their partners are of childbearing potential.

Exclusion Criteria:

1. History of symptomatic orthostatic hypotension with a decrease of ≥20 mmHg in systolic blood pressure (SBP) or decrease of ≥10 mmHg in diastolic blood pressure (DBP) when changing from a supine to a standing position after having been in the supine position for at least 5 minutes or SBP less than 105 mmHg in a supine position at screening;
2. Clinically significant history of gastrointestinal, cardiovascular, musculoskeletal, endocrine, hematologic, psychiatric, renal, hepatic, bronchopulmonary, neurologic, immunologic, and/or lipid metabolism disorders, and/or drug hypersensitivity;
3. History of epilepsy, seizures as an adult, lifetime history of stroke, or transient ischemic attack (TIA) within 1 year prior to screening;
4. History of sleep attacks or narcolepsy;
5. Known or suspected malignancy within 5 years with the exception of treated and cured basal cell carcinoma (skin), squamous cell carcinoma (skin), or in-situ cervical carcinoma;
6. Positive blood screen for human immunodeficiency virus (HIV) antibody, hepatitis B surface antigen (HBsAg), or hepatitis C antibody;
7. Positive pregnancy test result or plan to become pregnant if female;
8. Female who is pregnant or breastfeeding or of childbearing potential without adequate contraception (see Inclusion Criterion 7);
9. Hospital admission or major surgery within 30 days prior to screening;
10. Receipt of another investigational product within one month or 5 half-lives of the other investigational product, whichever is longer, before study drug administration in this study.
11. History of prescription drug abuse or any illicit drug use within 6 months prior to screening;
12. History of alcohol abuse according to medical history within 6 months prior to screening;
13. Positive screen for alcohol or drugs of abuse;
14. Unwillingness or inability to comply with food and beverage restrictions during study participation;
15. Donation or blood collection of more than 1 unit (approximate 450 mL) of blood (or blood products) or acute loss of blood during the 90 days prior to screening;
16. Use of prescription or over-the-counter (OTC) medications and/or herbal supplements (including St John's Wort, herbal teas, garlic extracts) within 14 days prior to dosing (Note: Use of acetaminophen at <3 g/day is permitted until 24 hours prior to dosing);
17. Inability to tolerate study drug in any prior rotigotine or LY03003 trial or intolerance or hypersensitivity to rotigotine or any excipients or diluents (Poly (lactide-co-glycolide) [PLGA], carboxymethylcellulose sodium [SCMC], stearic acid, or mannitol);
18. History of known intolerance/hypersensitivity to antiemetics such as ondansetron, tropisetron, and glycopyrrolate;
19. History of suicide attempt in the past 6 months and/or seen by the investigator as having a significant history of risk of suicide or homicide;
20. Unwillingness of male participants to use appropriate contraceptive measures (see Inclusion Criteria 8) if engaging in sexual intercourse with a female partner of childbearing potential throughout the study and for at least 1 month after the end of the study;
21. Unwillingness to refrain from sexual intercourse with pregnant or lactating women throughout the study and for at least 1 month after the end of the study;
22. Any other clinically relevant hepatic, renal, hematologic, and/or cardiac dysfunction, or other medical condition, or clinically significant laboratory abnormality that would interfere with the subject's safety or study outcome in the judgment of the investigator.
23. A lifetime history of bipolar I disorder, bipolar II disorder, cyclothymia or other specified bipolar and related disorders.
