NCT ID NCT06742801
First seen Jun 25, 2026 · Last updated Sep 21, 2026 · Updated 5 times
Summary
This study tests a liquid agent called Onyx™ that is injected into arteries to block active bleeding outside the heart and brain. It includes 119 adults with severe bleeding from trauma, ulcers, or other causes. The goal is to see if it safely stops bleeding without needing further procedures.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Onyx™ Liquid Embolic System (a liquid agent injected to block bleeding arteries)
- What this could lead to
- If successful, this could provide a safe and effective way to stop severe bleeding in trauma or ulcers without surgery.
- What could go wrong
- This is an early-stage study with only 119 participants. The treatment may fail to stop bleeding or cause unintended blockages. Long-term safety is not yet known.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patient is ≥ 22 years old. 2. Active arterial bleeding in the peripheral vasculature confirmed by radiologic and/or endoscopic imaging and deemed suitable for embolization treatment by the investigator. In this study, peripheral vasculature is defined as outside the brain and heart. 3. Patient or legally authorized representative (LAR) is able to provide written consent to participate in the study. 4. Life expectancy of \>30 days, in the opinion of the investigator at the time of enrollment. 5. Target treatment area is free from prior embolization treatment. Exclusion Criteria: 1. Pregnant or breastfeeding. 2. Symptoms of active infection. 3. Patient is known to be participating in the study of an investigational drug, biologic, or device. 4. Contrast allergy or other contraindication to angiography, CT, or catheterization, including contrast sensitivity that cannot be adequately treated prior to index procedure. 5. Known allergy to components of Onyx™. 6. Target vasculature unsuitable for the delivery of Onyx™ based upon physician assessment. 7. More than 4 target lesions will require embolization, in the investigator's opinion after imaging-based assessment.
