Clinical Trial Summary

The purpose of this study is to conduct the initial clinical investigation of the Foldax Polymer Mitral Valve to collect evidence on the device's safety and performance. The study is anticipated to confirm successful clinical safety and clinical effectiveness with significant improvements in clinical hemodynamic performance.

Description:

The Foldax Polymer Mitral Valve is indicated as a replacement for a diseased, damaged, or malfunctioning native mitral heart valve via open heart surgery. This is a first in human study conducted under US FDA's Early Feasibility Investigational Device Exemption and will enroll up to 15 patients. These patients will be followed up to 5 years after implantation.

Recruitment information / eligibility

• Status: Active, not recruiting
• Enrollment: 15
• Est. completion date: December 2025
• Est. primary completion date: December 2025
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Is 18 years or older

• Is a candidate for mitral valve replacement with cardiopulmonary bypass

• Is a candidate for mitral valve replacement due to:

• Moderate to severe mitral valve stenosis,

• Moderate to severe mitral valve regurgitation, or

• Moderate to severe mixed mitral stenosis/regurgitation

• Able to withstand short term anticoagulation

• Willing and able to comply with protocol requirements

Exclusion Criteria:

• Prior mitral valve surgery for valve replacement or valve repair (this does NOT include percutaneous interventions i.e. Mitraclip, chordal replacement)

• Requires emergency surgery

• Requires other planned surgery within 12 months of valve replacement

• Active endocarditis or active myocarditis

• Acute preoperative neurological deficit defined as neurological deficit < 3 months prior to enrollment

• Non-cardiac illness resulting in a life expectancy of less than 12 months

• Enrolled in another investigational device or drug study (enrolled patients may not enroll in other studies)

• Myocardial infarction, or severe cardiac adverse event which has not returned to baseline for at least 30-days prior to enrollment

• Aortic aneurysm or other medical condition that creates a higher than usual risk of surgical complications

• Renal or hepatic failure

• Hematological disorders, patients must not have a hematocrit of <30%, hemoglobin <10 g/dL, platelet count of <100,000 cells/µL, or WBC <4,000 cells/µL; coagulation profile must not be outside of normal limits

• Patients who are prisoners or mentally ill

• Patients who are pregnant or expect to become pregnant in the 12 months following implantation, or are lactating

• Has a positive test result for COVID-19 virus (baseline or preoperative)

• Patients who have withdrawn after implantation may not re-enter

• Intraoperatively it is determined that the patient anatomy is not compatible with the device.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Primary Safety Endpoints	Adverse Event (AE) rates for valve related early and late complications : thromboembolism, valve thrombosis, major hemorrhage, major paravalvular leak, endocarditis, structural valve deterioration, nonstructural valve dysfunction, valve related hemolysis, all cause death, valve related reoperation, valve explant, and valve related death. Results are visually compared to event rates reported in the literature.	12 months following patient enrollment completion
Primary	Primary Effectiveness Endpoints- Change in Hemodynamic Performance	Hemodynamic performance parameters are mmHG mean gradient and derived Effective Orifice Area (EOA). Success is defined as clinically significant improvement in hemodynamic performance (Effective Orifice Area (EOA)) at one year based on literature reports for surgical aortic valve replacement.	12 months following patient enrollment completion
Primary	Clinical Effectiveness: Change in New York Heart Association Assessment	Clinically significant improvement (one grade) in the New York Heart Association (NYHA) functional classification status at 365 days compared to baseline. a. Class I - No symptoms and no limitations in ordinary physical activity, e.g. shortness of breath when walking, climbing stairs etc. b. Class II - Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity. c. Class III - Marked limitation in activity due to symptoms, even during less-than-ordinary activity, e.g. walking short distances (20-100m). Comfortable only at rest. d. Class IV - Severe limitations. Experiences symptoms even while at rest. Mostly bedbound patients.	12 months following patient enrollment completion
Secondary	Number of Participants with Stroke	Assessment of patient experiencing a stroke (ex; ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, or other) verified by imaging and or physical exam	5 years following patient enrollment
Secondary	Number of Participants with Transient Ischemic Attack	Assessment of patient having a TIA as verified by imaging and or physical exam	5 years following patient enrollment
Secondary	Number of Participants with Migration of the TRIA valve	Assessment of patient experiencing valve migration as verified by imaging, procedure, or physical exam.	5 years following patient enrollment
Secondary	ICU Duration of Stay	Length of stay in the ICU post valve implantation defined as arrival time/date in hours and minutes to transfer to floor time/date in hours and minutes.	30 days post patient enrollment
Secondary	Ventilation Time	Ventilation time in hours defined as arrival time/date in recovery in hours and minutes to date and time extubated in hours and minutes	30 days post patient enrollment
Secondary	New Onset Atrial Fibrillation	New/post-operative atrial fibrillation - confirmed on ECG after closure during initial or subsequent admission or at one-year review	12 months post patient enrollment
Secondary	Readmission within 30 days of discharge	Patient readmission to the hospital post discharge measured by date/time	30 days post patient discharge date
Secondary	Post Procedure length of stay	l. Post procedure length of stay defined as the time/date documented for arrival in the recovery unit to date/ time of discharge in hours and minutes.	30 days post patient enrollment
Secondary	Kansas City Cardiomyopathy Questionnaire (KCCQ)	Change in QOL as measured by the KCCQ. Scores are measured from 0-100, in hich higher scores reflect better health status.	12 months post patient enrollment
Secondary	Six Minute Walk Test	Change in patients activity tolerance as documented by a 6 Minute Walk Test assessed by distance traveled after 6 minutes	12 months post patient enrollment
