研究概览

简要总结

This was a randomized, placebo-controlled, investigator- and participant-blinded study to evaluate the efficacy, safety, tolerability, and pharmacokinetics (PK) of HSY244 in participants with atrial fibrillation (AF), with and without heart failure (HF).

详细描述

A screening period of up to 3 days (72 hours) was used to assess eligibility. After eligibility was confirmed, patients were randomized to either HSY244 or placebo. Prior to study drug administration, pre-dose assessments were completed. After the start of study drug administration, the participant was monitored for cardioversion to sinus rhythm. If a participant was still in AF at 90 minutes after the start of study drug administration, direct current cardioversion was planned to be applied at a time deemed appropriate by the investigator.

入选标准

  • At screening, written informed consent were required to be obtained before any assessment was performed and only participants able to provide written informed consent themselves were included in this study.
  • Hemodynamically stable men and women (either of non-child-bearing potential or child bearing potential with highly effective contraception) between 18 and 80 years of age (inclusive) at screening with a clinical indication for direct current cardioversion of AF.
  • At screening, current episode of AF had been ongoing for ≥6 hours and ≤60 days
  • Successful initiation and achievement of therapeutic levels of national guideline and institution-specific anticoagulation therapy as appropriate for the duration of the AF episode and risk for the participant.
  • Completion of national guideline and institution-specific imaging evaluation for left atrial thrombi as appropriate for the duration of AF episode and risk for the participant.
  • At screening, participants were required to weigh at least 60 kg to participate in the study and were required to have a body mass index (BMI) within the range of 18 - 45 kg/m^
  • BMI = Body weight (kg) / [Height (m)]^2
  • At screening, vital signs (systolic blood pressure and pulse rate) were assessed in the sitting position. Sitting vital signs were required to be within the following ranges (exclusive):
  • systolic blood pressure between 100-160 mmHg and diastolic blood pressure 60-100 mmHg
  • pulse rate (ventricular rate) between 60-120 bpm.

排除标准

  • Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they were using highly effective methods of contraception during dosing and for 4 days after stopping of investigational drug.
  • Sexually active males unwilling to use a condom during intercourse while taking investigational drug and for 96 hours after study drug administration. A condom was required for all sexually active male participants to prevent them from fathering a child AND to prevent delivery of the investigational drug via seminal fluid to their partner. In addition, male participants could not donate sperm for the time period specified above.
  • Use of any anti-arrhythmic class I or III drug (including Ranolazine [Ranexa]) within 5 half lives before randomization; including use of amiodarone within 3 months before randomization.
  • At screening, history of current diagnosis of ECG abnormalities or cardiac rhythm disorders as determined by the Investigator's interpretation of the ECG findings indicating a significant risk for participating in the study, such as:
  • History of Torsades de Pointes (TdP), any other polymorphic ventricular tachycardia, sustained monomorphic ventricular tachycardia, long QT syndrome, or Brugada syndrome.
  • Wolfe-Parkinson-White (WPW) syndrome
  • In the absence of a complete bundle branch block a resting QTcF >460 msec for men and >470 msec for women (mean of ≥ 5 consecutive QT intervals)
  • In the presence of a complete bundle branch block, a prolonged QTcF or JTc that, in the opinion of the investigator, may pose a risk to patient safety
  • Third-degree (complete) heart block, or second-degree Mobitz type II heart block
  • Attempted or unsuccessful cardioversion within 2 weeks prior to randomization.
  • Presence of known severe mitral regurgitation and/or known severely dilated left atrium.
  • Pre-existing or tachycardia-induced moderate to severe cardiac dysfunction (New York Heart Association Class III and IV).
  • History within the preceding 3 months prior to randomization of: myocardial infarction, unstable angina, cardiac surgery, or a percutaneous coronary intervention.
  • History of a confirmed stroke or transient ischemic attack (TIA).
  • History or current diagnosis of any seizure disorder, epilepsy, significant head trauma, or other disorders increasing the risk for seizures.
  • History or current diagnosis of a major neurologic or psychiatric disorder that, in the opinion of the investigator, poses a risk to patient safety to participate.

结局指标

主要结局

Number of Participants With Conversion to Sinus Rhythm for at Least 1 Minute Within 90 Minutes From the Start of Study Drug Administration.

时间窗: 90 minutes from the start of study drug administration

Conversion to sinus rhythm was monitored using a Holter monitoring device through 90 minutes after the start of study drug administration. If a participant had been monitored for at least 45 minutes and did not convert to sinus rhythm for at least one minute, the primary endpoint was defined as 'no'. If a participant converted to sinus rhythm for at least one minute at any time during the post-treatment 90 minutes observation period, regardless of the length of time monitored, the primary endpoint was to be defined as 'yes'.

次要结局

  • Time to Reach the Maximum Concentration After Drug Administration (Tmax)(Day 1 (0 min (pre-dose), 15 min (end of infusion), 30 min , 60 min, 90 min and 180 min) and Day 5)
  • Area Under the Plasma Concentration-time Curve (AUClast)(Day 1 (0 min (pre-dose), 15 min (end of infusion), 30 min , 60 min, 90 min and 180 min) and Day 5)
  • Maximum Observed Plasma Concentration (Cmax)(Day 1 (0 min (pre-dose), 15 min (end of infusion), 30 min , 60 min, 90 min and 180 min) and Day 5)
