Humacyte Humanes azelluläres Gefäß (HAV) bei Patienten mit Gefäßtrauma

1. Juli 2026 aktualisiert von: Humacyte, Inc.

Eine Phase-2-Studie zur Bewertung der Sicherheit und Wirksamkeit des humanen azellulären Gefäßes von Humacyte für den Gefäßersatz oder die Rekonstruktion bei Patienten mit lebens- oder gliedmaßenbedrohlichen Gefäßverletzungen

Diese Studie bewertet die Verwendung des Human Acellular Vessel (HAV) bei Erwachsenen mit Gefäßtrauma unterhalb des Halses, die sich einer vaskulären rekonstruktiven Operation unterziehen. Es wird eine Torso-Kohorte und eine Gliedmaßen-Kohorte geben. Allen Probanden wird ein HAV als Zwischengefäß oder Bypass unter Verwendung von standardmäßigen vaskulären chirurgischen Techniken implantiert. Es gibt keinen Kontrollarm.

Detaillierte Beschreibung

Dies ist eine prospektive, multizentrische, nicht randomisierte Phase-2-Studie mit mehreren Kohorten an bis zu 40 erwachsenen Patienten mit lebens- oder gliedmaßenbedrohlichen Gefäßtraumata, die einer chirurgischen Reparatur bedürfen. Es wird eine Extremitäten-Kohorte und eine Torso-Kohorte geben. Die Gliedmaßenkohorte umfasst Patienten, die eine Reparatur eines in der oberen oder unteren Extremität eingeschlossenen Gefäßes benötigen. Die Torso-Kohorte umfasst Patienten, die eine Reparatur von Gefäßen im Thorax (ohne Herz), Abdomen und Retroperitoneum benötigen. Den Probanden wird ein humanes azelluläres Gefäß (HAV) von Humacyte als Zwischengefäß oder Bypass unter Verwendung von standardmäßigen vaskulären chirurgischen Techniken implantiert. Es gibt keinen Kontrollarm.

Die aktive Studiendauer für jeden Studienteilnehmer beträgt 36 Monate ab HAV-Implantation oder bis HAV-Versagen/Entfernung/Tod, falls früher. Die Nachsorge nach dem 12. Monat beinhaltet die Erfassung von Informationen zu Bewertungen, die bei routinemäßigen Klinikbesuchen nach dem „Standard der Versorgung“ oder per telefonischer Nachsorge mit dem Patienten oder seinem Arzt mit körperlicher Untersuchung und Ultraschall in Monat 24 und Monat 36 durchgeführt werden

Die erwartete Gesamtdauer der klinischen Studie beträgt 61 Monate (24 Monate nach Aufnahme und 36 Monate Nachbeobachtung).

Intervention / Behandlung
Experimental: 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.
Biologisch: Acellular Tissue Engineered Vessel (ATEV)
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.

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Primary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the All HAV Group
Zeitfenster: 30 days from time of implantation
Rate of primary patency at the specified milestone post-implantation, evaluated across the entire overall study population who received the Human Acellular Vessel (HAV). Primary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the evaluation milestone, without requiring any intervening surgical or endovascular interventions to maintain or re-establish flow.
30 days from time of implantation
Primary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the Extremity Community-Acquired Trauma Subgroup
Zeitfenster: 30 days from time implantation
Rate of primary patency at 30 days post-implantation, evaluated strictly within the sub-cohort of participants presenting with non-iatrogenic, community-acquired extremity vascular trauma. Primary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the 30-day evaluation milestone, without requiring any intervening surgical or endovascular interventions to maintain or re-establish flow.

Secondary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the All HAV Group
Zeitfenster: 30 days from time of implantation
Rate of secondary patency at the specified milestone post-implantation, evaluated across the entire overall study population who received the Human Acellular Vessel (HAV). Secondary patency is defined as the continuous presence of blood flow through the HAV conduit from the time of surgical placement until the evaluation milestone, including vessels that became occluded but were successfully restored to patency via intervening endovascular or surgical re-intervention (e.g., thrombectomy, thrombolysis, or patch angioplasty).
30 days from time of implantation
HAV Infection Free Rate at Day 30 in the All HAV Group
Zeitfenster: 30 days from time of implantation
The percentage of participants who remained entirely free from a confirmed, adjudicated infection of the implanted Human Acellular Vessel (HAV) conduit through the specified follow-up milestone, evaluated across the entire overall study population. An infection event is defined by clinical signs coupled with microbiologic confirmation from wound/perigraft cultures, or an independent clinical adjudication confirming a graft-specific infectious complication requiring targeted antibiotic therapy, surgical debridement, or explantation.
30 days from time of implantation
Limb Salvage Rate at Day 30 in the All HAV Group
Zeitfenster: 30 Days from time of implantation
Rate of successful limb salvage at the specified milestone post-implantation, evaluated across the entire overall study population who received the Human Acellular Vessel (HAV). Limb salvage is defined as the preservation of the treated upper or lower extremity without the requirement for a major secondary amputation (defined as an amputation performed at or proximal to the wrist or ankle joints) during the follow-up window.
30 Days from time of implantation
Survival Rate at Day 30 in the All HAV Group
Zeitfenster: 30 Days from time of implantation
Survival at the specified milestone post-implantation, evaluated across the entire overall study population who received the Human Acellular Vessel (HAV). Under While-on-Treatment analysis all cases without any evidence of death are imputed as having survived.
