Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This study tests a device that removes blood clots from the lungs of people with acute pulmonary embolism and then returns the cleaned blood back to their body. The goal is to see if this approach is safe and effective at reducing blood loss and complications. About 39 adults with intermediate-risk clots will be enrolled.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
AlphaReturn Blood Management System (device that returns filtered blood to the body after clot removal)
What this could lead to
If successful, this could make clot removal safer by reducing blood loss and the need for transfusions in people with acute pulmonary embolism.
What could go wrong
This is a small early study with only 39 participants, so results may not apply to everyone. There is a risk of device-related complications like bleeding or injury to blood vessels.
Why investors are watching

AngioDynamics is testing its AlphaReturn blood management system alongside its cleared AlphaVac device in 39 patients with acute pulmonary embolism. For a small-cap company, this readout matters because it could expand the approved use of an existing product line, adding a new revenue source without a full new-device launch.

If it works: A positive safety and effectiveness result could support regulatory clearance for AlphaReturn in this setting, giving AngioDynamics a broader product story in clot removal. That could strengthen its position with hospitals and potentially open a larger market for its vascular devices.

If it fails: The trial could fail to show adequate safety or effectiveness, or enrollment and data collection could stall. Trials in small patient groups often miss their goals, and a negative result would likely limit AlphaReturn's use in pulmonary embolism and slow the company's growth plans.

Inclusion Criteria: A potential subject will be included in the study if he/she meets all the following inclusion criteria: 1. Provision of signed and dated informed consent form. 2. Subject is 18 years of age and older. 3. Subject presents clinical signs and symptoms consistent with acute intermediate-risk pulmonary embolism for less than or equal to 14 days. 4. Subject has a diagnosis of pulmonary embolism detected from computed tomography angiography (CTA). 5. Subject has a RV/LV ratio of 0.9 or higher. 6. Subject has a systolic blood pressure (SBP) of 90mmHg or higher. 7. Subject has a heart rate of 130 beats per minute (BPM) or less prior to the procedure. 8. Subject is deemed medically eligible for interventional procedure(s) per institutional guidelines and/or clinical judgment. Exclusion Criteria: A potential subject will be excluded from the study if he/she meets any of the following exclusion criteria: 1. Subjects who are or may be pregnant as determined by a positive pregnancy test or who are breastfeeding. 2. Subjects who have any contraindication to systemic or therapeutic doses of heparin or anticoagulants. 3. Subjects who have used thrombolytics in the 30 days prior to the baseline CTA. 4. Subjects who have pulmonary hypertension with peak pulmonary artery pressure (PAP) \> 70 mmHg. 5. Subjects who have FiO2 requirement \> 44% or \> 6 LPM to keep oxygen saturations \> 90%. 6. Subjects with hematocrit \< 28% within 6 hours of index procedure. 7. Subjects with platelets count \< 100,000/μL. 8. Subjects with serum creatinine \> 1.8 mg/dL. 9. Subjects with International Normalized Ratio (INR) \> 3. 10. Subjects who have undergone a major trauma within the past 14 days of the index procedure and have Injury Severity Score (ISS) \> 15. 11. Subjects with the presence of cancer requiring active chemotherapy. 12. Subjects with known bleeding diathesis or coagulation disorder. 13. Subjects who have had a cardiovascular or pulmonary surgery within the past 7 days of index procedure. 14. Subjects with a history of severe or chronic pulmonary hypertension, uncompensated heart failure, chest irradiation, underlying lung disease that is oxygen dependent, heparin-induced thrombocytopenia (HIT) and/or chronic left heart disease with left ventricular ejection fraction ≤ 30%. 15. Subjects with known anaphylactic reaction to radiographic contrast agents that cannot be pretreated. 16. Subject requires vasopressor after fluids to keep pressure ≥ 90mmHg. 17. Subjects with left bundle branch block. 18. Subjects who have intracardiac lead in the right ventricle or atrium. 19. Evidence such as imaging or other that suggest the subject is not appropriate for this procedure. 20.
