CORCYM Mitral, Aortic aNd Tricuspid Post-maRket Study in a reAl-world Setting

The MANTRA Master Plan (Master Protocol) is intended as an overarching Umbrella Protocol that allows multiple substudies to be added, as needed. The Umbrella Master Protocol concept offers an excellent solution to provide post-marketing clinical follow-up information on the entire cardiac surgery heart valve portfolio of the sponsor in a common database.

Currently, three substudies are planned:

• MANTRA - Aortic Sub-Study
• MANTRA - Mitral/Tricuspid Sub-Study (excluding Memo 4D)
• MANTRA - Memo 4D Sub-Study

The aim of the studies assembled under the master protocol is the continued collection of safety and performance data during heart valve procedures and the relevant follow-up visits in subjects where any of the CORCYM devices and accessories are used in a real-world setting, in accordance with the IFUs, and at the discretion of the investigator.

MANTRA study is expected to enroll approximately 2150 subjects in up to 130 sites worldwide:

• Approximately 1650 subjects considered suitable for treatment with a CORCYM aortic device
• Approximately 300 subjects considered suitable for treatment with a CORCYM mitral and/or tricuspid device (excluding Memo 4D)
• Approximately 200 subjects considered suitable for treatment with Memo 4D

Expected enrollment duration may vary across the different projects. Subject follow-up is planned at discharge, 30 days after implantation and then annually up to 10 years. Sites can choose to participate in one or more sub-studies.

All available data shall be gathered during standard medical care.

At a minimum, the following data will be collected:

• Informed Consent
• Screening/Baseline data, including demographics and medical history
• Procedural data
• Hospitalization and Discharge data
• Follow-up data: 30 days and annually up to 10 years post procedure
• Serious Adverse Event and Device Deficiencies information

As part of the study, the subject will be asked to complete quality of life questionnaire(s) at baseline, 30 days and at 1-year follow-up.

In addition, for the MEMO 4D sub-study only, an Echocardiography Core Laboratory has been appointed by the Sponsor to assess the hemodynamic and structural performance, annular motion and dynamics, and 3D echocardiogram images (transesophageal during the procedure and transthoracic during follow up) will be collected for Corelab readings.
