About this study

Official title: A Randomized, Placebo-controlled, Investigator- and Participant-blinded Study to Evaluate the Efficacy, Safety, Tolerability, and Pharmacokinetics of HSY244 in Participants With Atrial Fibrillation

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).

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Conversion to Sinus Rhythm for at Least 1 Minute Within 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'.

    Measured: 90 minutes from the start of study drug administration

Secondary outcomes (3)
  1. Maximum Observed Plasma Concentration (Cmax)

    The Cmax is the maximum (peak) observed plasma drug concentration after single-dose administration.

    Actual recorded sampling times were taken into consideration for PK calculations.

    Measured: Day 1 (0 min (pre-dose), 15 min (end of infusion), 30 min , 60 min, 90 min and 180 min) and Day 5

  2. Time to Reach the Maximum Concentration After Drug Administration (Tmax)

    Tmax is the time to reach maximum (peak) plasma drug concentration after single dose administration (time).

    Actual recorded sampling times were taken into consideration for PK calculations.

    Measured: Day 1 (0 min (pre-dose), 15 min (end of infusion), 30 min , 60 min, 90 min and 180 min) and Day 5

  3. Area Under the Plasma Concentration-time Curve (AUClast)

    AUClast is the AUC from time zero to the last measurable concentration sampling time (tlast).

    Actual recorded sampling times were taken into consideration for PK calculations.

    Measured: Day 1 (0 min (pre-dose), 15 min (end of infusion), 30 min , 60 min, 90 min and 180 min) and Day 5

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States, Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
