Prevention study for Peripheral Vascular Diseases
Official title A Contrast Medium Sparing Strategy Using Automated CO2 Injection During PVI for Prevention of Major Adverse Kidney Events (MAKE)
ClinicalTrials.gov ID: NCT06656988
What this study is testing
What is CO2?
CO2 is an investigational medicine, given as an injectable medicine, being studied as a potential treatment for peripheral vascular diseases.
Also referred to as carbon dioxide.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The primary objective of the trial is to evaluate if an iodinated contrast medium sparing strategy using automated Carbon Dioxide (CO2) Injection prevents Major Adverse Kidney Events up to 90 days (MAKE90) in patients at moderately elevated risk for contrast-associated acute kidney injury (CA-AKI) undergoing infrainguinal peripheral vascular interventions (PVI).
- Phase 3: a large, late-stage study
- Which group you join is decided by chance.
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
Who can take part
Ages 18 and older
You may be able to join if
- Symptomatic peripheral arterial disease presenting with either acute symptoms (Rutherford clinical categories I-IIb) or chronic symptoms (Fontaine...
- Planned peripheral vascular intervention of infrainguinal arteries due to femoropopliteal and/or infrapopliteal lesions
