AWANS, Belgium, March 29, 2022 /PRNewswire/ — Miracor Medical SA (Miracor Medical) today announced the first patient enrolled in the PICSO-AMI-V study to evaluate the benefits of PiCSO® (Pressure Controlled Intermittent Coronary Sinus Occlusion) therapy as an adjunct to conventional primary percutaneous coronary intervention (PCI) for patients with ST-segment elevation lower myocardial infarction (STEMI).
“Improving outcomes for patients with significant heart attacks remains a significant unmet need.”
The first patient registered was taken care of at the University Hospital of Toulouse, France by the team of Professor Didier Carrié (Drs T. Lhermusier and F. Campelo). “Our team began using PiCSO therapy for anterior STEMI patients in 2021. We are excited to explore new indications and now begin using PiCSO for inferior STEMI patients as part of the PiCSO-AMI study- v. said Professor Carrié.
The study’s principal investigator is Professor Adrian Banning, Oxford Heart Centre, Oxford, UK. “We are pleased to initiate the PiCSO-AMI-V study. He will explore the potential of PiCSO therapy to improve outcomes for patients with heart attacks affecting the lower side of the heart. The study builds on data from the First-In-Man study that we published in 20213. We know that improving outcomes for patients with major heart attacks remains a significant unmet need, particularly because these patients often progress to heart failure.“says Professor Banning.
PICSO-AMI-V is a prospective, randomized, multicenter feasibility study that will enroll 75 lower STEMI patients with TIMI 0 and 1 flow, at up to 10 clinical sites in Europe. In the study, patients will be randomized 2:1 to a group receiving PiCSO as an adjunct to their primary PCI procedure versus a conventional strategy of primary PCI alone. The adverse device event (ADE) rate 30 days after the indexing procedure will be assessed as the primary endpoint. In addition, cardiac function and clinical safety endpoints – including death, heart failure-related hospitalization, new or worsening heart failure – will be assessed. Patients will be followed for 1 year.
PiCSO therapy has demonstrated positive results in several clinical studies. Data from two recent studies (“PiCSO in ACS” and “OxAMI-PICSO”) have shown that use of the PiCSO Impulse System is associated with a significant reduction in infarct size in prior STEMI patients 1.2. In addition, OxAMI-PICSO3 showed early improvement in coronary microvascular function after PiCSO treatment in anterior and inferior STEMI patients. PiCSO therapy accelerates microcirculatory recovery, resulting in a significant reduction in MRI (microcirculatory resistance index) and RRR (resistive reserve ratio) after the procedure compared to controls.
“We are excited to start this second randomized clinical trial in Europe and to advance our strategy to expand indications beyond our initial anterior STEMI indication. The PiCSO-AMI-V Inferior STEMI study will complement the ongoing PiCSO-AMI-I (Anterior STEMI) study, which has enrolled over 100 prior STEMI patients and is expected to complete enrollment in the second half of this year. We also recently processed the 300and patient with PiCSO therapy, illustrating acceleration of use and therapy experience“, says Olivier Delporte, CEO of Miracor Medical.
PiCSO therapy is used during the primary PCI procedure in acute myocardial infarction (AMI). Through its unique differentiated mechanism of action, the PiCSO Impulse System clears coronary microcirculation by intermittently obstructing coronary sinus outflow. Use of the PiCSO Impulse System has been associated with a reduction in infarct size after STEMI, leading to reduced heart failure hospitalizations and reduced mortality4. Heart failure develops in 18-28% of patients 90 days after their STEMI 5.
The PiCSO-AMI-V Inferior STEMI study is partially funded by a recoverable cash advance granted by the Walloon Region to Miracor Medical.
