Clinical Trial Summary

The Impella ECP Study is a prospective, multi-center, single-arm study evaluating the rate of major adverse cardiovascular and cerebrovascular events (MACCE) with the Impella ECP device in adult patients undergoing elective or urgent high-risk percutaneous coronary intervention. The above applies to Impella ECP Continued Access Protocol


Clinical Trial Description

This is a prospective, multi-center, single-arm study evaluating the major adverse cardiovascular and cerebrovascular event (MACCE) rate of the Impella ECP device in adult patients undergoing elective or urgent high-risk percutaneous coronary intervention (HRPCI). Additionally, this study will evaluate safety related to Impella ECP-related major vascular complications and Impella ECP-related major bleeding. Finally, this study will evaluate secondary endpoints including the occurrence of major hemolysis, aortic valve injury, escalation of care to Impella CP, and the length of hospital stay. Investigational device products include: Impella ECP pump system (a percutaneous transvalvular micro-axial blood pump), 9Fr introducer sheath, and the automated Impella controller (AIC) with revised console software to allow control of the Impella ECP. Study flow: Following informed consent, subjects eligible for a HRPCI that meet all of the inclusion and none of the exclusion criteria will be enrolled into the Study. Subjects will undergo Impella ECP placement through a femoral sheath, following crimping of the Impella ECP. The intended coronary intervention will be performed with the mechanical circulatory support provided by the Impella ECP. Once the procedure is completed, the device is weaned and removed. Subjects will be followed for 30 days. Subjects will be treated based on the contemporary AHA/ACC/SCAI practice guidelines throughout the duration of the Study. A sample size of two hundred seventeen (217) subjects with 30-day follow-up is needed for 90% power at a one-sided 0.05 significance level. Assuming 15% loss-to-follow-up, up to two hundred fifty-six (256) subjects will be enrolled. Safety endpoints will be presented as summary statistics without formal hypothesis testing. The MACCE rate will be assessed against the PG of 24.4% at one-sided 5% significance level. Impella ECP Continued Access Protocol: Description, Investigational device and study flow remains the same as above. A sample size up to three hundred (300) subjects will be enrolled at up to 25 sites. Sites must have been activated in the Pivotal to be eligible for the Continued Access Protocol. ;
