There is one clinical trial.
This randomized, double-blind, placebo controlled, study will be conducted to evaluate the safety, tolerability, and pharmacokinetics of ST-2427. The study will be conducted in 2 parts. In Part A of this study, subjects will be randomized to receive a single dose of ST-2427 or placebo in a Single Ascending Dose (SAD) design. In Part B of this study, subjects will be randomized to receive up to 6 repeat doses of ST-2427 or placebo, administered twice-daily (BID) every 12 hours, in a Multiple Ascending Dose (MAD) design. In Part A and Part B, study drug (ST-2427 or placebo) will be administered intravenously (IV) over 1 hour. A total of 48 subjects will be enrolled. Subjects will be randomized in a 4:2 ratio of ST-2427 to placebo. Study drug will be blinded to all subjects and investigators.
Description: For purposes of monitoring safety, treatment-emergent adverse events (AEs) will be graded using the Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers (FDA 2007) which is appropriate for healthy subjects.
Measure: Incidence and severity of treatment-emergent adverse events Time: Day 1 through Day 8Description: Blood pressure, including orthostatic blood pressure (BP; diastolic blood pressure [DBP], systolic blood pressure [SBP], will be used to analyze for change from baseline.
Measure: Incidence and severity of adverse events assessed by blood pressure Time: Day 1 through Day 8Description: Cardiodynamic evaluation will be performed to evaluate the treatment effects on heart rate-corrected QT interval using the Fridericia (QTcF) corrections, using concentration-QTc analysis, and on other ECG parameters (heart rate, PR and QRS interval and treatment emergent T and U-wave abnormalities).
Measure: Incidence and severity of adverse events assessed by ECG Time: Day 1 through Day 8Description: The Holter recordings will also be analyzed for the presence of arrhythmias and for derivation of heart rate variability (HRV).
Measure: Incidence and severity of adverse events assessed by Continous Holter Monitoring Time: Day 1 through Day 8Description: Descriptive statistics will be used to evaluate the treatment effects on clinical laboratory assessments including clinical chemistry, hematology, and urinalysis.
Measure: Incidence and severity of treatment-emergent events assessed by clinical laboratory assessments Time: Day 1 through Day 8Description: Body weight (kg) will be assessed for changes relative to baseline.
Measure: Incidence and severity of adverse events assessed by body weight Time: Day 1 through Day 8Description: PK modeling will be performed using compartmental methods. The maximum concentration of ST-2427 in whole blood after the ST-2427 infusion in the SAD, and after the first and fifth infusions of ST-2427 in the MAD will be measured.
Measure: Pharmacokinetics of ST-2427 concentration in whole blood: Cmax Time: Day 1 through Day 5Description: PK modeling will be performed using compartmental methods. The elimination half-life of ST-2427 in whole blood after the ST-2427 infusion in the SAD, and after the first and fifth infusions of ST-2427 in the MAD will be measured.
Measure: Pharmacokinetics of ST-2427 concentration in whole blood: Elimination half-life Time: Day 1 through Day 5Description: PK modeling will be performed using compartmental methods. The AUC (area under the curve) of ST-2427 in whole blood after the ST-2427 infusion in the SAD, and after the first and fifth infusions of ST-2427 in the MAD will be measured.
Measure: Pharmacokinetics of ST-2427 concentration in whole blood: Area under the curve Time: Day 1 through Day 5Description: The ST-2427 concentrations in the urine will be measured in 4 hour increments by cohort for the SAD.
Measure: Pharmacokinetics of ST-2427 concentration in urine Time: Day 1 through Day 5
