Tissue Engineered Veins in Patients With Chronic Venous Insufficiency — TECVI-1  

Chronic Venous Insufficiency Clinical Trial

Official title:
Phase I Open-label, First-in-human Study to Evaluate Feasibility and Safety of Tissue Engineered Veins in Patients With Chronic Venous Insufficiency

Clinical Trial Summary

This study aims to evaluate the safety (incidence of adverse events including serious adverse events and clinical significant laboratory abnormalities) of personalized tissue engineered veins (P-TEV) with valves implanted in patients with severe chronic venous insufficiency (CVI). For each patient a segment of the femoral vein containing the non-functioning valve will be surgically replaced with a single P-TEV containing a functioning valve.

Clinical Trial Description

The advanced therapy medicinal product (ATMP) described herein is a personalized tissue- engineered vein (P-TEV) graft for use in surgical implantation to replace a defective or missing part of a patient's vein. In this specific application a P-TEV graft with a functioning venous bicuspid valve is implanted to replace a nonfunctioning venous valve in the femoral vein of a patient suffering from severe CVI. The P-TEV graft for surgical implantation is 4-6 cm in length. The P-TEV drug substance consists of an extracellular matrix (ECM) scaffold in the form of a decellularized (DC) allogeneic vein scaffold which is populated with autologous components from the patient's own peripheral whole blood (PWB) in an ATMP manufacturing process performed under GMP. As the allogeneic immunogenic material has been removed from the donated vein segment by DC and as the perfusion uses autologous PWB, no immunosuppression is required. Successful implantation and treatment should prevent the reverse blood flow, decrease blood pooling in the lower leg, and thereby alleviate symptoms such as swelling, pain, and ulcers. ;
