The Effect of CS-3150 Exposure on Corrected QT (QTc) Interval Duration in Healthy Volunteers

Study Overview
=================
Brief Summary
-----------------
This study will test if a study drug (CS-3150) will affect the heart rate in healthy males and females. Two doses of the study drug will be tested. Heart rate is not expected to be different between the study groups.

Detailed Description
-----------------
This study will assess the effect of therapeutic and supratherapeutic plasma exposures of CS-3150 on the corrected QT (QTc) interval duration after administration of single oral 10-mg and 40-mg doses of CS-3150 in healthy male and female participants. This study will also determine the safety and tolerability of CS-3150 administration, assess the effect on electrocardiogram (ECG) parameters, detect QT interval (QT)/QTc prolongation with a positive control (moxifloxacin), characterize pharmacokinetics (PK) of CS-3150, and assess exposure-response relationship of CS-3150 on QTc.

QTcF interval duration > 450 ms for male and female obtained as an average from the triplicate screening ECGs after at least 10 min in a fully supine quiet rest. Abnormal waveform morphology on any of the screening ECGs that would preclude accurate measurement of the QT interval duration. Family history of congenital Long QT syndrome (LQTS), a history of surviving an unexplained drowning episode, a history of any form of syncope or loss of consciousness, or known symptomatic cardiac arrhythmias. Known allergy to moxifloxacin. An estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease (MDRD) equation lower than 90 mL/min. Previous participation in a CS-3150 study within 6 months prior to the single dose of CS-3150. History or current evidence of clinically significant cardiac, hepatic, renal, pulmonary, endocrine, neurologic, infectious, gastrointestinal, hematologic, or oncologic disease as determined by the PI after reviewing screening history, physical examination, laboratory test results, and 12-lead ECG Clinically significant illness (at the discretion of principal investigator) within 4 weeks of first dose, are carriers of Hepatitis B surface antigen (HBsAg), Hepatitis C antibody (HCV), or human immunodeficiency virus (HIV) antibody, and any other reason not deemed suitable for the study (at the discretion of the principal investigator).
