Positive Late-breaking Clinical Trial Data for the EkoSonic™ Endovascular System Presented at VIVA21
Boston Scientific (NYSE: BSX) announced positive findings for its EkoSonic™ Endovascular System at the Vascular InterVentional Advances (VIVA) meeting in Las Vegas. The KNOCOUT PE registry, which studied 489 patients across 83 centers, demonstrated the system's safety and efficacy in treating pulmonary embolism (PE) with a lower drug dose and shorter infusion duration. Notably, no intracerebral hemorrhagic events occurred, and the major bleeding rate was just 2.5%. The results also indicated a 23% reduction in heart strain post-procedure, underscoring the system's potential to enhance patient care.
- The KNOCOUT PE registry involved 489 patients across 83 centers, showcasing broad institutional adoption.
- No intracerebral hemorrhagic events were reported, indicating strong safety.
- The major bleeding rate was only 2.5%, significantly lower than traditional treatment rates.
- A 23% reduction in the right ventricular to left ventricular diameter ratio post-procedure suggests effective treatment outcomes.
- None.
LAS VEGAS and MARLBOROUGH, Mass., Oct. 5, 2021 /PRNewswire/ -- Today, Boston Scientific (NYSE: BSX) announced positive results for the EkoSonic™ Endovascular System (EKOS system) during a late-breaking clinical trial presentation at the Vascular InterVentional Advances (VIVA) meeting in Las Vegas. Data from the KNOCOUT PE registry – established to measure institutional adoption of a lower dose and lower-duration thrombolysis protocol for the EKOS system – confirmed the safety and efficacy of the EKOS system for the treatment of patients with intermediate-high and high-risk pulmonary embolism (PE).
"PE remains a life-threatening and complex disease, but these results provide an opportunity to advance patient care by showcasing evidence that proves a lower drug dose and shorter infusion duration of a thrombolytic agent may result in enhanced safety and efficacy," said Keith M. Sterling, M.D., FSIR, Inova Alexandria Hospital, Alexandria, VA, study principal investigator.i "The findings in this registry analysis are very reassuring to physicians making critical evidence-based decisions for their patients in what are oftentimes emergent treatment situations."
The international registry of 489 patients across 83 centers included data from patients treated with the EKOS system who were provided a lower drug dose and shorter infusion duration of a thrombolytic agent than administered in previous studies, reflecting contemporary clinical practice. In the data, there were no intracerebral hemorrhagic (ICH) events, or brain bleeding events, with a low major bleedingii rate of
"As the largest prospective body of evidence in the interventional PE space to date, the KNOCOUT PE registry provides an accurate modern representation of patients with PE treated with the EKOS system every day," said Michael R. Jaff, D.O., chief medical officer and vice president clinical affairs, technology and innovation, Peripheral Interventions, Boston Scientific. "The strong safety and efficacy findings exhibited in this registry add to the existing clinical evidence supporting the EKOS system as a treatment option that physicians can trust, as it is already the most studied interventional device in the PE space."
The ultrasound technology used by the EKOS system accelerates thrombolysis – the breakdown of the clot – minimizing the time it takes to treat a patient and lowering the necessary thrombolytic dose, which can result in optimized outcomes and a lower risk of bleeding.
