About the research

The goal of this multicenter, double-blind, randomized controlled trial is to learn if sivelestat sodium (Siv) can protect the organ function in patients suffered operation for acute type A aortic dissection. The main questions it aims to answer are:

  • Can the 3-day-treatment of Siv enlarge the Day-0-to-Day-5 drop in the organ-health score (SOFA score)?
  • Can this treatment significantly shrink the area under the SOFA curve from first dose to Day 5?
  • Can this treatment significantly improve the end of patients in 28 days (clinical outcomes)? Researchers will compare drug Siv to a placebo (a look-alike substance that contains no drug) to see if drug Siv works.

Participants will:

  • Take drug Siv or the placebo through vein continuously for 72 hours
  • Receiving regular intensive care in ICU after the operation

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

Inclusion Criteria:

1. Age 18-75 years inclusive.
2. Written informed consent obtained before participation.
3. Confirmed acute Stanford type A aortic dissection scheduled for surgical repair.

Exclusion Criteria:

1. Life expectancy ≤ 48 hours.

Sivelestat group

Drug: Sivelestat Sodium. Procedure: Conventional Treatment

Procedure: Conventional treatment · Drug: Sivelestat sodium

Control group

Drug: Placebo. Procedure: Conventional Treatment

Procedure: Conventional treatment · Drug: Placebo

Conventional treatment PROCEDURE

Beside the using of Sivelestat Sodium or placebo, all postoperative care will adhere to each center's standard protocols for type A aortic dissection.

Sivelestat sodium DRUG

The daily dose (4.8 mg/kg) is diluted in 48 mL of 0.9 % saline and administered as a continuous intravenous infusion over 24 hours at 2 mL/h (equivalent to 0.2 mg/kg/h) for 72 consecutive hours.

Placebo DRUG

An equal volume of placebo-containing only the excipients of sivelestat sodium and diluted to 48 mL with 0.9 % saline-will be infused at 2 mL/h for 72 consecutive hours.

What researchers are measuring

Outcome measures describe what is being studied. They are not proof that a treatment works.
