Trial summary

Liver transplantation (LT) is a high-risk surgery for hemodynamic instability and haemorrhagic shock with a high-risk of acute kidney injury (AKI). Indeed, the incidence of post-transplant AKI exceeds 50% in some series with 15% of patients requiring renal replacement therapy. Read more about this study

About this study

Official title: Effect of Low-dose Arginine-vasopressin Supplementation on Post-transplant Acute Kidney Injury After Liver Transplantation

Liver transplantation (LT) is a high-risk surgery for hemodynamic instability and haemorrhagic shock with a high-risk of acute kidney injury (AKI). Indeed, the incidence of post-transplant AKI exceeds 50% in some series with 15% of patients requiring renal replacement therapy. Acute kidney injury after LT is a predisposing factor for chronic renal failure which is independently associated with higher morbidity and mortality.

Arginine vasopressin (AVP), an essential stress hormone released in response to hypotension, binds to AVPR1a to promote vasoconstriction. Furthermore, it may have nephroprotective effects with a preferential vasoconstriction of the post-glomerular arteriole resulting in increased glomerular filtration

The hypothesis of the present work is that low-dose arginine-vasopressin supplementation reduce posttransplant AKI in liver transplantation.

Read the detailed description

Prospective, national multicenter, double-blinded, randomized , controlled superiority trial with two parallel arms : AVP vs Norepinephrine

The primary objective is to demonstrate that intraoperative low-dose supplementation of AVP induces a reduction in posttransplant AKI after liver transplantation

Investigational medicinal product: vasopressin will be administered by continuous infusion. AVP will be used to a final concentration of 0.12 U/ml. The vasopressor infusion will be titrated to maintain an MAP of at least 65 mmHg. The study-drug infusion will be started at 5 ml/h and increased by 2.5 ml/h to achieve a maximum target rate of 30 ml/h, so that AVP doses ranged from 0.01 to 0.06 U/min.

Comparator treatment : norepinephrine will be administered by continuous infusion. Norepinephrine will be used with final concentrations of 120 microg/ml. The vasopressor infusion will be titrated to maintain an MAP of at least 65 mmHg. The study-drug infusion will be started at 5 ml/h and increased by 2.5 ml/h to achieve a maximum target rate of 30 ml/h, so that NE doses ranged from10 to 60 microg/min.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Arginine vasopressin and Norepinephrine in people with Acute Kidney Injury Post Liver Transplantation, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 4 inclusion and 10 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: looking for participants now, as of the sponsor's last update on 5 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Jacques DURANTEAU, Pr (01 45 21 34 41 ext. +33, jacques.duranteau@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The primary objective is to compare the effect of intraoperative low-dose supplementation of AVP vs norepinephrine infusions on post-transplant Acute Kidney Injury after liver transplantation. (time frame: during the first 7 postoperative days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06344442, which also lists 13 linked publications.

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 5 Feb 2026.
