New device sucks blood clots from lungs in acute PE trial
NCT ID NCT06697314
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial is testing a device called AlphaVac that suctions blood clots out of the lung arteries in people with acute pulmonary embolism (PE). The study will enroll 256 adults with a confirmed PE and signs of heart strain. The main goals are to see if the device reduces heart strain within 48 hours and to track safety over 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AlphaVac multipurpose mechanical aspiration (MMA) F1885 system (a device that suctions out blood clots)
- What this could lead to
- If it works, this could offer a less invasive way to quickly remove dangerous blood clots from the lungs, potentially reducing heart strain and the need for clot-busting drugs.
- What could go wrong
- This is a single-arm study with no comparison group, so results may be less reliable. The device may not work for everyone, and there are risks like bleeding or damage to blood vessels.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Symptomatic, CTPA-proven acute PE with a maximum duration of symptoms of 14 days, showing a filling defect in at least one main or proximal lobar pulmonary artery * RV/LV diameter ratio ≥ 1.0 assessed by CTPA * Serum troponin levels above upper limit of normal as per hospital policy * ≥ 18 years of age * At least one of the following: 1. Electrocardiogram (ECG)-documented tachycardia with heart rate ≥ 100 BPM, not due to hypovolemia, arrhythmia or sepsis 2. Systolic blood pressure ≤ 110mmHg for at least 15 minutes 3. Respiratory rate \> 20 breaths per minuted. Oxygen saturation on pulse oximetry (SpO2) \< 90% (or partial arterial oxygen pressure \< 60 mmHg) at rest while breathing room air 4. Known history of heart failure * Willing and able to provide written informed consent prior to receiving study specific procedures. Exclusion Criteria: * A contraindication to therapeutic anticoagulation * Any comorbid diagnosis consistent with a life expectancy of less than 1 year (e.g., stage 4 cancer) * Known serious, uncontrolled sensitivity to radiographic agents * Cardiac arrest within last 14 days without documented evidence of recovery of conscious level to Glasgow Coma Scale \>12 * Indication for ECMO * Pregnant or breastfeeding * Participation in another investigational drug or device study that study may confound the results of this study. Studies requiring extended follow-up for products that were investigational but have since become commercially available are not considered investigational studies. * Other medical, social, or psychological conditions that, in the opinion of the Investigator, precludes the patient from appropriate consent, could limit the patient's ability to participate in the study, including compliance with follow- up requirements, or that could impact the scientific integrity of the study. * History of congenital or acquired bleeding disorder predisposing to hemorrhagic state * Platelet count \< 100,000/μL * Any advanced reperfusion therapy for pulmonary embolism within 30 days of the index procedure (e.g lysis, surgery, catheter intervention) * A known clot in transit * IVC filter * A do not resuscitate limitation at inclusion in the study * Deprived of liberty or under court protection
