Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does require that you are actively receiving certain nephrotoxic medications. If you are taking imipenem-cilastatin or probenecid, you must stop at least 48 hours before joining the trial.

How does the drug cilastatin differ from other treatments for acute kidney injury?

Cilastatin is unique because it protects the kidneys from damage caused by certain drugs like gentamicin and cisplatin without affecting their effectiveness. It works by preventing harmful substances from entering kidney cells and reducing cell damage, making it a novel option for preventing drug-induced kidney injury.12345

What is the purpose of this trial?

The goal of this clinical trial is to repurpose cilastatin for preventing acute kidney injury (AKI) in hospitalized patients receiving nephrotoxic medications. The trial will evaluate the efficacy of the re-purposed drug.The main questions it aims to answer are:- whether cilastatin will prevent nephrotoxic AKI in hospitalized patients.Researchers will compare the drug cilastatin to a placebo (a look-alike substance that contains no drug) to see if drug cilastatin works to prevent AKI in hospitalized patients receiving nephrotoxic medications.Participants will:* Receive drug Cilastatin or a placebo intravenously every 6 hours for up to 24 hours after last exposure to nephrotoxic medication* Have blood test for kidney function every day they are on treatment.* Have a follow-up blood test at 90 days after randomization* Have a telephone survey at 90 days after randomization

Trial Overview The study is testing whether cilastatin can prevent acute kidney injury in patients exposed to harmful medications. It involves comparing cilastatin given intravenously every 6 hours against a saline placebo, with both groups monitored closely for changes in kidney function.
