Humacyte Human Acellular Vessel (HAV) u pacientů s vaskulárním traumatem

1. července 2026 aktualizováno: Humacyte, Inc.

Studie fáze 2 pro hodnocení bezpečnosti a účinnosti lidské acelulární cévy Humacyte pro vaskulární náhradu nebo rekonstrukci u pacientů s vaskulárním traumatem ohrožujícím život nebo končetinu

Tato studie hodnotí použití lidské acelulární cévy (HAV) u dospělých s vaskulárním traumatem pod krkem, kteří podstupují vaskulární rekonstrukční operaci. Bude to kohorta trupu a kohorta končetin. Všem subjektům bude implantován HAV jako interpoziční céva nebo bypass za použití standardních vaskulárních chirurgických technik. Neexistuje žádné ovládací rameno.

Detailní popis

Toto je prospektivní, multicentrická, multikohortní, nerandomizovaná studie fáze 2 u až 40 dospělých pacientů s vaskulárním traumatem ohrožujícím život nebo končetinu, které vyžaduje chirurgickou opravu. Bude existovat kohorta končetin a kohorta trupu. Kohorta končetiny bude zahrnovat pacienty, kteří vyžadují opravu cévy na horní nebo dolní končetině. Skupina trupu zahrnuje pacienty, kteří vyžadují opravu cév v hrudníku (kromě srdce), břiše a retroperitonea. Subjektům bude implantována Humacyte Human Acellular Vessel (HAV) jako interpoziční céva nebo bypass za použití standardních vaskulárních chirurgických technik. Neexistuje žádné ovládací rameno.

Aktivní doba trvání studie pro každého účastníka studie bude 36 měsíců od implantace HAV nebo do selhání/odstranění/úmrtí HAV, pokud dříve. Sledování po 12. měsíci bude zahrnovat zachycení informací o hodnoceních prováděných při rutinních návštěvách kliniky „standardní péče“ nebo telefonické sledování pacienta nebo jeho lékaře s fyzikálním vyšetřením a ultrazvukem ve 24. a 36. měsíci.

Celková očekávaná délka klinické studie je 61 měsíců (24 měsíců zařazení a 36 měsíců sledování).

Experimentální: 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.
Biologický: 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.

Časové okno
Primary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the All HAV Group
Časové okno: 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
Časové okno: 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.

Časové okno: 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).
