A Study of Etripamil in Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
The objectives of the study are as below: Primary: ·To evaluate the pharmacokinetics (PK) of Etripamil in healthy adult Chinese subjects Secondary: To evaluate the pharmacodynamics (PD) of Etripamil in healthy adult Chinese subjects To evaluate the safety and tolerability of Etripamil in healthy adult Chinese subjects Exploratory: ·To evaluate the PK exposure-PD response relationship of etripamil in healthy adult Chinese subjects

Detailed Description
-----------------
This is a randomized, double-blind, placebo-controlled phase 1 study in healthy adult Chinese subjects to evaluate the PK, PD, safety and tolerability of single dose of etripamil, 70 mg nasal spray (NS). After signing the informed consent form (ICF), potential subjects will undergo screening procedures within 28 days prior to dosing. Eligible subjects will be admitted to the clinical unit on Day -1 and screening procedures will be repeated to confirm eligibility. Subjects will fast overnight for at least 10 hours prior to dosing. 12 healthy adult Chinese subjects will be randomized to receive etripamil 70 mg single dose (n=10) or placebo (n=2). Blood and urine samples will be collected for PK assessments of etripamil and the inactive main metabolite MSP-2030. AEs, 12-lead ECGs, clinical laboratory tests, vital signs, physical examinations, and concomitant medications will be collected and evaluated over the course of study. Subjects will remain in clinic until discharged on Day 2. There will be a follow-up telephone call on Day 11 (±1 day) of dosing. Total duration for each subject will be approximately 1.5 months.
