Trial summary

Cardiac surgery associated acute kidney injury (CSA-AKI) has been recognized as the second most common cause of hospital acquired AKI. The development of CSA-AKI is independently associated with an increased risk of in-hospital death. Read more about this study

About this study

Official title: Validation of AKI-Sapere Model to Predict Patients at Risk for AKI After Cardiac Surgery: GUARD-AKI (GUiding Against Reserve Decline)

Cardiac surgery associated acute kidney injury (CSA-AKI) has been recognized as the second most common cause of hospital acquired AKI. The development of CSA-AKI is independently associated with an increased risk of in-hospital death. There are currently no biomarkers that could identify patients at higher risk for AKI and current risk predictor scores that are based on clinical and demographic information are inadequate. Therefore, a diagnostic test for predicting AKI risk in this clinical context would assist clinicians to optimize surgical strategy and postoperative care to prevent CSA-AKI occurrence and improve patient outcomes.

The primary purpose of this study is to validate a panel of biomarkers identified in the discovery study (referred to as AKI-Sapere prognostic) to identify patients at risk for all stages of CSA-AKI.

What is being measured

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

  1. Development of stage 1 or higher postoperative AKI as defined by the KDIGO classification (stage 1 = sCr value of ≥0.3 mg/dL in the first 48h or a relative increase of ≥50% in peak sCr from baseline within 7 days post-surgery)

    Measured: within 7 days post-surgery

Secondary outcomes (6)
  1. Development of moderate to severe AKI (sCr increase of ≥100% within 7 days post surgery or a sCr increase of ≥100% from baseline within 7 days and urine output <0.5 mL/kg/h for >12h)

    Measured: within 7 days post-surgery

  2. Development of 30-day persistent kidney impairment (eGFR change of ≥25% from baseline at the 30-day follow-up visit)

    Measured: 30 days post-surgery

  3. Development of new onset atrial fibrilation

    Measured: within 7 days post-surgery

  4. Development of 30-day major adverse kidney events (MAKE30): a composite of persistently impaired renal function (sCr increase of ≥0.5 mg/dL from baseline [pre-surgery]), new dialysis, and death

    Measured: 30 days post-surgery

  5. Development of 30-day major adverse cardiac events (MACE30): a composite of myocardial infarction (MI), stroke, heart failure, and death

    Measured: 30 days post-surgery

  6. Development of the combination of MAKE30 and MACE30 (major adverse reno-cardiovascular events [MARCE30])

    Measured: 30 days post-surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Artery Disease, run by Sapere Bio at 3 sites in United States.

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 2 inclusion and 11 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: finished, as of the sponsor's last update on 4 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Development of stage 1 or higher postoperative AKI as defined by the KDIGO classification (stage 1 = sCr value of ≥0.3 mg/dL in the first 48h or a relative increase of ≥50% in peak sCr from baseline within 7 days post-surgery) (time frame: within 7 days post-surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Apr 2023.
