Description détaillée
Il s'agit d'une étude de phase 2 prospective, multicentrique, multicohorte et non randomisée portant sur jusqu'à 40 patients adultes présentant un traumatisme vasculaire menaçant la vie ou les membres et nécessitant une réparation chirurgicale. Il y aura une cohorte des membres et une cohorte du torse. La cohorte des membres comprendra des patients qui nécessitent la réparation d'un vaisseau contenu dans le membre supérieur ou inférieur. La cohorte du torse comprend des patients qui nécessitent une réparation des vaisseaux dans le thorax (à l'exclusion du cœur), l'abdomen et le rétropéritoine. Les sujets seront implantés avec un vaisseau acellulaire humain Humacyte (HAV) en tant que vaisseau d'interposition ou pontage en utilisant des techniques chirurgicales vasculaires standard. Il n'y a pas de bras de contrôle.
La durée de l'étude active pour chaque participant à l'étude sera de 36 mois à compter de l'implantation du VHA ou jusqu'à l'échec/le retrait/le décès du VHA si cela se produit plus tôt. Le suivi après le 12e mois impliquera la saisie d'informations sur les évaluations effectuées lors des visites cliniques de routine « standard de soins » ou par un suivi téléphonique avec le patient ou son médecin avec un examen physique et une échographie au mois 24 et au mois 36
La durée totale prévue de l'étude clinique est de 61 mois (24 mois d'inscription et 36 mois de suivi).

Critère d'intégration:
- Patients présentant une lésion traumatique menaçant la vie ou les membres d'un vaisseau artériel du membre ou du torse, autre que le cœur, nécessitant un remplacement ou une reconstruction
- L'imagerie préopératoire ou l'examen clinique indique que le vaisseau endommagé a une longueur de défaut ≤ 38 cm et sa taille est adaptée au vaisseau acellulaire humain (VHA) de 6 mm selon le jugement du chirurgien traitant en tenant compte de la vasoconstriction et des considérations situationnelles d'entrée et de sortie.
- La greffe veineuse autologue n'est pas réalisable selon le jugement du chirurgien traitant (par exemple en raison du manque de disponibilité d'un conduit approprié, de la présence d'une insuffisance veineuse sévère) ou n'est pas souhaitable en raison de l'urgence de la revascularisation
- De 18 à 85 ans inclus
- Capable de communiquer de manière significative avec le personnel d'enquête et capable de se conformer à l'ensemble des procédures d'étude.

Expérimental: 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.
