Overview of the trials
The trial data show three interventional studies of ANGIOTENSIN II in very different patient groups.[1][2][3] These studies are authorised and include a low-intervention study, a Phase 2 study, and a Phase 3 study.[1][2][3]
The trials are designed to test whether ANGIOTENSIN II can improve important clinical outcomes in patients with acute kidney injury, liver cancer, and refractory hypotension in distributive shock.[1][2][3]
Trial in acute kidney injury after cardiac surgery
One study is titled “Reduction of occurence of Acute Kidney Injury through administration of angiotensin II versus Noradrenaline” and is registered as NCT06615102.[1] It is an interventional, low-intervention trial with 1,022 participants and status Authorised.[1]
This trial studies adults with acute kidney injury after cardiac surgery and asks whether ANGIOTENSIN II, used as the primary vasopressor, can reduce the occurrence of moderate or severe kidney injury within 72 hours after surgery.[1] The comparison treatment is noradrenaline, which is another blood-pressure medicine used in the study.[1]
The main outcome is the rate of AKI KDIGO stage 2 or 3 or death within 72 hours after cardiac surgery.[1] KDIGO is a kidney injury grading system, and stage 2 or 3 means more serious kidney damage.[1]
Trial in liver cancer and radioembolization
Another study is the RADIANT study, registered as 2025-521870-33-00.[2] It is a Phase 2 interventional trial with 15 participants and status Authorised.[2]
This trial includes patients with liver cancer, either primary or secondary, and studies ANGIOTENSIN II during radioembolization, which is a treatment that delivers radiation inside the liver blood vessels.[2] In this study, ANGIOTENSIN II is given intra-arterially, meaning directly into an artery.[2]
The main question is whether ANGIOTENSIN II improves the tumor-to-non-tumor ratio after treatment with 90Y glass microspheres compared with the ratio seen after 99mTc-MAA without ANGIOTENSIN II.[2] In simple words, the researchers want to know if more of the treatment reaches the tumor and less reaches normal tissue.[2]
Trial in children with life-threatening low blood pressure
The third study is registered as 2025-523750-14-00 and is a Phase 3 interventional trial with 143 participants.[3] It is authorised and studies patients aged 0–17 years with refractory hypotension in distributive shock.[3]
This trial compares ANGIOTENSIN II with placebo while children are already receiving fluid resuscitation and standard-of-care vasopressors.[3] The study is designed to see whether ANGIOTENSIN II can lower the amount of standard blood-pressure medicine needed.[3]
The main outcome is the change in the dose of standard-of-care vasopressors, measured as norepinephrine base equivalent dose from baseline to the first 6 hours of treatment.[3] This tells researchers whether the study medicine helps reduce the need for other blood-pressure support.[3]
Main outcomes and what they mean
Each trial uses a different endpoint, which means the main result the researchers want to measure.[1][2][3]
In the kidney study, the endpoint is whether a patient develops stage 2 or 3 acute kidney injury or dies within 72 hours after cardiac surgery.[1]
In the liver cancer study, the endpoint is the improvement factor in tumor-to-non-tumor ratio after radioembolization.[2]
In the pediatric shock study, the endpoint is the change in vasopressor dose during the first 6 hours of treatment.[3]
These endpoints show that the trials are not just looking at whether ANGIOTENSIN II can be given, but whether it changes important patient outcomes.[1][2][3]
Who may take part
The trial populations are very specific, and each study focuses on a different group of patients.[1][2][3]
Adults after cardiac surgery who are at risk of acute kidney injury can be included in the kidney study.[1]
Patients with primary or secondary liver cancer can be included in the RADIANT study.[2]
Children and teenagers aged 0–17 years with refractory hypotension in distributive shock can be included in the Phase 3 pediatric study.[3]
Because the studies are in different conditions and age groups, the entry rules are not the same across trials.[1][2][3]
