Plain English summary of protocol

Background and study aims
This study will assess new Eurosets cannulae used for extracorporeal circulation and compare them with currently marketed Maquet HLS cannulae.

Who can participate?
Patients aged 18 years and older requiring extracorporeal circulation.

What does the study involve?
The investigation is divided into two phases.
• In Phase I, 22 patients will be enrolled to confirm safety.
• If safety is demonstrated, Phase II will enrol about 100 patients in total to test whether Eurosets cannulae are not inferior to Maquet cannulae regarding performance.
Performance will be measured as blood drainage and reinfusion pressures during extracorporeal circulation.

Patients requiring veno-arterial extracorporeal circulation will be randomized to receive either Eurosets or Maquet cannulae.
Data will be collected on cannula pressures, blood lactate, procedure duration, ease of use, integrity of the cannulae, and hospital stay.


What are the possible benefits and risks of participating?
There are possible clinical benefits associated with the use of the devices under investigation in terms of clinical performance and biocompatibility parameters compared to the currently available cannulas.

No additional risks attributable specifically to the devices under investigation are foreseen compared to the standard ECC procedure. The risks associated with the use of other commercially approved devices are managed and mitigated according to the standard practice in place at the investigational sites for the procedures to be implemented in this clinical investigation.

Where is the study run from?
Eurosets S.r.l.

When is the study starting and how long is it expected to run for?
July 2024 to December 2026

InterventionThe research protocol for evaluating Drainage and Return Cannulas is structured as a comprehensive two-phase study, the first aimed at ensuring safety and the second aimed at evaluating the performance of the investigational devices.

Phase I
• Clinical investigation Type: Pre-market, pilot, interventional, randomized, stratified by BSA, multicenter.
• Participants: 22 patients.
• Outcome Measures: Safety (primary), standard deviation, and non-inferiority margin for performance (secondary).
• Randomization: 1:1 between investigational Drainage and Return Cannulas and CE-marked comparator Cannulas in the same patient.

Phase II
• Clinical investigation Type: Pre-market, pivotal, interventional, randomized, stratified by BSA, non-inferiority, multicenter.
• Participants: Considering a drop-out rate of 15%, 100 subjects (50 subjects per group) will participate in the Clinical investigation between Phase I and Phase II. This number is a pure estimation, since the actual sample size will be recalculated based on the result of Phase I analysis.
• Outcome Measures: Safety, performance of Drainage and Return Cannulas.
• Randomization: 1:1 between investigational Drainage and Return Cannulas and CE-marked comparator Cannulas in the same patient.

The randomisation ensures unbiased allocation of subjects between study arms and will be implemented as follows:
• Subjects will be randomly assigned in a two-arm 1:1 allocation (Investigational vs. Control), with 22 subjects in Phase I (11 per arm) and approximately 78 subjects in Phase II (39 per arm, depending on Phase I outcomes). Randomisation will be stratified by Body Surface Area (BSA), using two predefined categories (1.40–1.95 m² and 1.96–2.50 m²)
• Block size: 4 subjects per block, ensuring that within each block, 2 subjects are assigned to the investigational arm and 2 to the control arm, maintaining a balanced distribution.
• The randomisation list will be generated and implemented within a secure electronic Case Report Form (eCRF) system, which uses a computer-based pseudo-random algorithm to ensure full unpredictability and reproducibility of the allocation sequence. The eCRF automatically assigns each subject to the appropriate treatment arm at enrolment while maintaining allocation concealment. All randomisation events are documented in the system audit trail, capturing date, time, and user identification to guarantee traceability and data integrity across all sites
This process guarantees an unbiased allocation and preserves the integrity of the study design across all sites.

• Arm A (investigational): Eurosets multistage femoral venous drainage cannulae (EUVFMULTI26C, EUVFMULTI28C) and return cannulae (EURET1716C, EURET1718C, EURET1720C).
• Arm B (control): Maquet HLS venous cannulae (BE-PVL 2555, BE-PVL 2955) and arterial cannulae (BE-PAL 1723, BE-PAL 2123).

Patients randomized 1:1. ECC management per local standard of care. Continuous monitoring of flow and cannula pressure.
