Recruiting studies
- NCT04374799RecruitingPhase 3
Heparin vs placebo during cardiac catheterization
This trial tests whether giving heparin (a blood thinner) during a specific type of heart procedure is safer and works better than not giving it. It focuses on patients where the blood supply in the hand’s artery connection is functioning properly.
Hamilton, OntarioAges 18 years+ - NCT03302195Recruiting

Jinan, ShandongAges 20–45 - NCT06109155RecruitingPhase 4
Comparing medications to reduce bleeding in heart surgery
This trial tests two medicines—ACT (a blood thinner) and tranexamic acid (a medicine to reduce bleeding)—to see which is better at controlling bleeding during heart surgery. It is for adults having planned heart surgery with a heart-lung machine.
TaichungAges 18 years+ - NCT07863115Recruiting
Preventing blood clots after leg injury with a cast
This study looks at a simple checklist to see who is at risk for blood clots after a leg injury that requires a cast or brace. It also checks how well people follow blood-thinning medication to prevent these clots.
MonastirAges 18 years+ - NCT07759167RecruitingPhase 1

Xi'an, ShaanxiAges 20–45 - NCT07477977Recruiting
Finding the right dose of protamine to reverse heparin after heart bypass
This study is testing different doses of a medication called protamine, which is given after heart surgery to reverse the effects of heparin (a blood thinner). The goal is to find the safest and most effective dose for patients who have had a heart-lung bypass machine during surgery.
SohagAges 18 years+ - NCT07434908Recruiting
Study of HBP and lung fluid in ICU patients
This trial looks at a protein called HBP in the blood and how it relates to fluid in the lungs. You can join if you are over 18 and already have a special heart monitor called PiCCO in place.
ÖstersundAges 18 years+ - NCT07302620Recruiting
Can heparin affect argatroban lab results?
This study looks at whether the presence of heparin (a common blood thinner) can interfere with the lab test used to measure another blood thinner called argatroban. If you are already having your heparin level checked, this study uses the same blood sample to see if heparin affects argatroban results.
StrasbourgAges 18 years+ - NCT07288489RecruitingPhase 3
A study on VMX-C001 for urgent surgery while on blood thinners
This trial tests a drug called VMX-C001 to quickly reverse the effects of certain blood thinners (Factor Xa inhibitors) in people who need urgent surgery with a high risk of bleeding. It compares VMX-C001 to standard care to see which is more effective at helping blood clot normally.
Chandler, ArizonaAges 18 years+ - NCT07183605Recruiting
How different ways of drawing blood from a central line compare for heparin activity
This trial checks whether blood samples taken from a central line using either a syringe flush or a vacuum tube give the same heparin activity results as blood from a vein in the arm. It is designed for patients in the ICU who are on a steady heparin drip.
OrléansAges 18 years+ - NCT06937372Recruiting
Blood clot risk after hip fracture; trial comparing care approaches
This trial compares two approaches for preventing blood clots in older adults who broke a hip. The goal is to find the safest and most effective way to manage clot risk after surgery.
LondonAges 60–120 - NCT06845423RecruitingPhase 4
Preventing blood clots after childbirth in women at intermediate risk
This study tests whether giving a short course of a daily blood-thinning injection (enoxaparin) after childbirth can safely prevent blood clots in women at intermediate risk. If you qualify, you would receive the injection or a placebo (inactive shot) for up to 5 days while in the hospital.
AmiensAges 18 years+ - NCT04049591Recruiting
Higher vs lower heparin dose during planned heart stent procedure
This trial compares a higher versus lower dose of heparin (a blood thinner) during a planned PCI, which is a heart procedure to open blocked arteries using a stent. It may help hospitals and patients know which dosing approach is safest and works well during the procedure.
Hamilton, OntarioAges 18 years+ - NCT06714864RecruitingPhase 4
Preventing catheter infections in children on dialysis
This study tests a liquid that is put into the dialysis catheter after each session to prevent infections that can happen through the catheter. It is designed for children up to age 18 who need hemodialysis through a catheter.

Common questions
- Are there clinical trials studying Heparin?
- Yes. Clin2 currently lists 57 recruiting studies that include Heparin, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Heparin trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Heparin an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Heparin or a specific trial is right for you.
