Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Acute kidney injury (AKI) is a well-recognized complication in critically ill patients, which often leads to the necessity of mechanical kidney support (CRRT).

In current therapeutic regimes, CRRT is used to strictly prevent azotaemia. Thus recent clinical observations, as well as data from animal testing suggest a link between controlled azotaemia and faster renal recovery in AKI patients.

The aim of the study is to improve renal recovery.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention Group

CRRT will be established with a draining dose (effluent dose) of 10-15ml/kg/h in pursuit of establishing a controlled azotaemia.

Group Type EXPERIMENTAL

Effluent dose of CRRT

Intervention Type OTHER

The effluent dose of the CRRT will be performed according to study group for 7 days or up to the end of CRRT, whatever occurs first.

Control Group

Standard of Care:

CRRT will be established with a draining dose (effluent dose) of 25-30ml/kg/h

Group Type ACTIVE_COMPARATOR

Effluent dose of CRRT

Intervention Type OTHER

The effluent dose of the CRRT will be performed according to study group for 7 days or up to the end of CRRT, whatever occurs first.
