Target enrollment:
Participant gender:
This is a randomized, open-label, 2-sequence, 2-treatment cross-over study in healthy adult subjects. Rotigotine PK profiles will be obtained from all subjects after both a single dose of 28 mg LY03003 and 1 week of 4 mg q24h NEUPRO® patch. Subjects will be randomized 1:1 to 1 of the 2 treatment sequences.

Inclusion Criteria:

1. Willing and capable of giving informed consent;

2. Between the ages of 18 and 45 years old, inclusive;

3. Healthy, per investigator's 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 restrictions, and
stay at the CRU during in-subject 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 another 90 days
after the end of the study to minimize the risk of pregnancy.

8. All male subjects must be willing to use a condom in combination with another
acceptable form of contraception (such as partner's use of a cap, diaphragm, sponge,
spermicide, or hormonal contraception. Of note, male and female condom combination is
NOT acceptable)during any sexual activity (e.g. vaginal, anal, oral) with women with
childbearing potential (WOCBP) even if the subjects have undergone a successful
vasectomy or if their partner is already pregnant or breastfeeding, from study drug
dosing, throughout the study, and for another 90 days after the end of study.

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

for at least 5 minutes or SBP less than 105 mmHg in a supine position at screening and

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;

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 and Baseline;

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. Presence of ink tattoos of any kind in any of the designated patch application sites.

12. History of prescription drug abuse or any illicit drug use within 6 months prior to
screening and Baseline;

13. History of alcohol abuse according to medical history within 6 months prior to
screening and Baseline;

(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

18. 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
