Detaljerad beskrivning
Detta är en prospektiv, multicenter, multikohort, icke-randomiserad fas 2-studie på upp till 40 vuxna patienter med livshotande kärltrauma som kräver kirurgisk reparation. Det kommer att finnas en lemkohort och en bålkohort. Lemkohorten kommer att inkludera patienter som behöver reparation av ett kärl som finns i den övre eller nedre extremiteten. Bålkohorten inkluderar patienter som behöver reparation av kärl i bröstkorgen (exklusive hjärtat), buken och retroperitoneum. Försökspersonerna kommer att implanteras med ett Humacyte Human Acellular Vessel (HAV) som ett interpositionskärl eller bypass med standard vaskulär kirurgisk teknik. Det finns ingen kontrollarm.
Den aktiva studietiden för varje studiedeltagare kommer att vara 36 månader från HAV-implantation eller till HAV-fel/borttagning/död om tidigare. Uppföljning efter månad 12 kommer att innebära insamling av information om bedömningar gjorda vid "standard of care" rutinmässiga klinikbesök eller per telefonuppföljning med patienten eller hans/hennes läkare med fysisk undersökning och ultraljud vid månad 24 och månad 36
Den totala förväntade varaktigheten av den kliniska studien är 61 månader (24 månaders inskrivning och 36 månaders uppföljning).

Experimentell: Acellular Tissue Engineered Vessel (ATEV)
Patients with life or limb threatening traumatic injury to an arterial vessel in the limb or torso, other than the heart, will be implanted with the Humacyte ATEV as an interposition vessel or bypass using standard vascular surgical techniques.
|
The investigational medicinal product (IMP) - the Acellular Tissue Engineered Vessel (ATEV) is a sterile acellular tubular graft composed of human collagen types I and III and other extracellular matrix proteins, including fibronectin and vitronectin which can be used for arterial bypass or reconstruction in patients with life or limb threatening vascular trauma.
The vessel is 6 mm in diameter and approximately 42 cm in length.
The product is supplied on a silicone mandrel immersed in sterile phosphate buffered saline in a sealed and labeled plastic container.
The ATEV is implanted using standard vascular surgical techniques similar to placement of predicate peripheral vascular prostheses.
