What is the purpose of this trial?

This trial tests a new treatment called Auxora for individuals with acute kidney injury (AKI) and breathing difficulties due to low oxygen levels. The goal is to determine if Auxora can improve kidney function compared to a placebo (a substance with no active medicine). Participants will receive infusions for five days. This trial may suit those diagnosed with severe AKI who require special oxygen support, such as a breathing machine. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you are currently receiving chemotherapy or immunosuppressive medications, you would not be eligible to participate.

Is there any evidence suggesting that Auxora is likely to be safe for humans?

Research shows that Auxora has been tested in patients with severe acute kidney injury (AKI). In these studies, researchers closely monitored Auxora's safety and patient tolerance. Most patients in earlier trials tolerated the treatment well. Some side effects were reported, but they were considered manageable.

Auxora is administered through infusions, delivering it directly into the bloodstream over a few days. This method allows doctors to control the dose and monitor safety. While these studies are ongoing, the current phase suggests a clearer picture of Auxora's safety, and more data will help confirm its safety for patients with AKI. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for acute kidney injury that mainly focus on supportive care like dialysis and managing fluid balance, Auxora offers a new approach by targeting cellular stress responses. Auxora is unique because it acts on calcium overload in cells, which is a key factor in kidney injury. Researchers are excited about Auxora because it has the potential to directly reduce kidney damage at the cellular level, potentially improving outcomes more effectively and quickly than existing treatments.

What evidence suggests that Auxora might be an effective treatment for acute kidney injury?

Research has shown that Auxora, which participants in this trial may receive, might help treat severe acute kidney injury (AKI) with breathing problems. One study found that patients who took Auxora had a 62.7% lower chance of dying within 30 days compared to those who received a placebo, and this benefit lasted up to 60 days. These results suggest that Auxora could lower the risk of death for patients with these conditions. While more research is needed, these findings offer hope that Auxora could assist those dealing with AKI and respiratory issues. ^{1 2 3 6 7}

Published Research Related to This Trial

Currently, there are no specific therapies approved for the prevention or treatment of acute kidney injury (AKI), and traditional care remains largely supportive.

Recent research has identified various potential compounds targeting different pathways involved in AKI, such as oxidative stress and inflammation, which are now entering early-phase clinical trials, showing promise for future treatment options.

New drugs for acute kidney injury. Côté, JM., Murray, PT., Rosner, MH.[2021]

In a study of 33,648 patients who underwent major surgery, the use of diuretics postoperatively was linked to nearly double the odds of developing acute kidney injury (AKI), while ACE inhibitors/angiotensin receptor blockers (ACEI/ARBs) showed a protective effect after cardiac surgery.

NSAIDs did not significantly increase the risk of AKI overall, but their use was associated with higher odds of AKI shortly after initial exposure, highlighting the importance of monitoring medication use in the postoperative period.

Acute kidney injury (AKI) affects 7% of hospitalized patients and up to 35% in intensive care, leading to increased mortality; early detection and differentiation of AKI types are crucial for effective management.

Preventive measures include maintaining adequate circulation and avoiding nephrotoxins, while treatment focuses on correcting underlying causes, monitoring electrolytes, and using protective agents to mitigate kidney damage.

Acute kidney injury (AKI) is increasingly common in hospitalized patients and is linked to high rates of illness and death, yet current treatments, including loop diuretics, have not shown significant benefits in improving outcomes.

The management of AKI remains primarily supportive, as no interventions, including other diuretics and natriuretic agents, have convincingly demonstrated effectiveness in preventing or treating this condition.

Diuretics in acute kidney injury. Nigwekar, SU., Waikar, SS.[2022]

The term 'Acute Kidney Injury' (AKI) has replaced 'Acute Renal Failure', and the classification of AKI has evolved to include three stages to better detect moderate cases, especially in ICU patients where over 30% are affected.

Management strategies for AKI emphasize optimal resuscitation and hydration to prevent contrast-induced nephropathy, while the effectiveness of loop diuretics and low-dose dopamine remains unproven, highlighting the need for further research on renal replacement therapy and dialysis protocols.
