A Randomized, Open-Label, Crossover Study to Evaluate the Pharmacokinetic Profiles of Rotigotine After a Single Dose of LY03003 (28 mg) Versus After a Week of Daily NEUPRO® Transdermal Patch (4 mg Every 24 Hours) in Healthy Volunteers

Overview

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.

Detailed Description

Sequence 1

Period 1:

Subjects will check into the clinical research unit (CRU) on Day 0. On Day 1, subjects will receive the first 4 mg NEUPRO® patch in the morning. On Days 2 to 7, subjects will receive a 4- mg NEUPRO® patch every 24 hours (+/- 30 minutes) on one of the 7 designated patch application sites (see Section 12.2). On Day 1, serial PK samples will be collected within 30 minutes prior to patch application and 2, 4, 8, 12, 16, 20 hours post patch application. On Days 2, 3, 4, 5 and 6, one PK sample will be collected pre-patch (<30 minutes pre-patch) application only. On Day 7, the subjects will receive the NEUPRO® patch and serial PK samples will be collected pre-patch (<30 mins pre-patch) application and at 2, 4, 6, 8, 12, 16, 20, 24, 26, 28, 30, 33, 36, and 48 hours post-patch application Subject will stay at CRU till Day 14 to complete the End of Treatment ( EOT) procedures and prepare for the LY03003 treatment in Period 2 on the next day.

Period 2:

On Day 1 in the morning, subjects will receive a single-dose IM injection of 28 mg LY03003. Serial PK samples will be collected within 30 minutes pre-dosing and at 0.5, 1, 6, and 12 hours post dosing on Day 1. On Days 2 to Day 8, Day 10, Day 12, Day 15, Day 17, and Day 22, one single post-dose PK sample will be collected at the following corresponding hours: 24, 48, 72, 96, 120, 144, 168, 216, 264, 336, 384, and 504 hours post dosing. Subjects will stay at CRU till Day 22 to have PK collected and EOT activities completed. Subjects will be discharged on the same day. A 7-day safety follow-up period will be followed with a call on Day 29.

Sequence 2 Period 1 Subjects will check into the CRU on Day 0. In the morning of Day 1, subjects will receive a single-dose IM injection of 28 mg LY03003. Serial PK samples will be collected within 30 minutes pre-dosing and at 0.5, 1, 6 and 12 hours post dosing on Day 1. On Days 2 to Day 8, Day 10, Day 12, and Day 15, Day 17, and Day 22, one single postdose PK sample will be collected at the following corresponding hours: 24, 48, 72, 96, 120, 144, 168, 216, 264, 336, 384, and 504 hours post dosing. On Day 22, Subjects will have PK samples collected and EOT activities completed. Subjects will stay at the CRU until Day 29 and complete a 7-day washout period and to prepare for NEUPRO® patch treatment in Period 2 on the next day.

Period 2 On Day 1, subjects will receive the first 4 mg NEUPRO® patch in the morning. On Days 2 to 7, subjects will receive a 4- mg NEUPRO® patch every 24 hours (+/- 30 mins) on one of the 7 designated patch application sites (see Section 12.2). On Day 1, serial PK samples will be collected within 30 minutes prior to patch application and 2,4, 8, 12, 16 and 20 hours post patch application. On Days 2, 3, 4, 5 and 6, one PK sample will be collected pre-patch (<30 minutes pre-patch) application only. On Day 7, the subjects will receive the NEUPRO® patch and serial PK samples will be collected pre-patch (<30 minutes pre-patch) application and at 2, 4, 6, 8, 12, 16, 20, 24, 26, 28, 30, 33, 36, and 48 hours post-patch application. Subjects will stay at CRU and continue the safety follow-up period until Day14. On Day 14, subjects will complete EOT activities, followed by being discharged from the study on the same day.

1. Willing and capable of giving informed consent;

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

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.
