Study of APAC for peripheral artery disease and severe leg ischemia
This trial tests a new drug called APAC to see if it safely prevents blood clots and improves blood flow in people with narrowed leg arteries. It may help those with severe symptoms like pain at rest or non-healing wounds, or those with claudication (leg pain when walking).
HelsinkiAges Up to 85 years - NCT06979284Recruiting
Ultrasound inside artery for severe leg blockages
This trial tests whether using a special ultrasound probe inside the artery (called intravascular ultrasound) helps guide treatment for people with severe leg artery blockages that cause pain, wounds, or gangrene. The goal is to see if it improves blood flow and saves the leg.
HamiltonAges 18 years+ - NCT06473740RecruitingPhase 4
Gene therapy plus angioplasty for severe leg blockages
This study tests if adding gene therapy to a standard leg artery-opening procedure (angioplasty or stenting) helps people with severe leg pain or non-healing wounds due to blocked arteries. It may improve blood flow and save the leg from amputation.
Blagoveshchensk, Amur OblastAges 18 years+ - NCT05971394Recruiting
Sirolimus stent for severe blocked leg arteries
This trial tests a special stent-like device placed in blocked arteries below the knee to improve blood flow in people with critical limb ischemia. If you meet the artery and health requirements, the goal is to reduce artery re-blocking and help prevent worsening leg problems over 12 months.
FlorenceAges 18–85 - NCT06204237RecruitingEarly Phase 1
PET imaging safety study for leg artery disease patients and healthy volunteers
This study tests whether a new radioactive tracer called APAC is safe and can be seen in PET/CT scans. It is for people with blocked leg arteries (PAOD/CLI) and for healthy volunteers. The goal is to see where the tracer goes in the body and how the body tolerates it.
GroningenAges 40–85 - NCT07006467Recruiting
Study of a dissolving scaffold for leg artery blockages
This trial tests a new type of absorbable scaffold (like a temporary mesh) that is placed inside a blocked artery below the knee to restore blood flow. It is for people with severe leg pain or small ulcers due to chronic limb-threatening ischemia (CLI) who have a short blockage in a specific artery.
GrazAges 18 years+ - NCT07052435Recruiting

Common questions
- Are there clinical trials for acute limb ischemia?
- Yes. Clin2 currently lists 27 recruiting acute limb ischemia studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a acute limb ischemia trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a acute limb ischemia trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
