Humacyte Human Acellular Vessel (HAV) potilailla, joilla on vaskulaarinen trauma

keskiviikko 1. heinäkuuta 2026 päivittänyt: Humacyte, Inc.

Vaiheen 2 tutkimus Humacyten ihmisen solusuonen turvallisuuden ja tehokkuuden arvioimiseksi verisuonten korvaamiseksi tai rekonstruoimiseksi potilailla, joilla on henkeä tai raajoja uhkaava verisuonitrauma

Tässä tutkimuksessa arvioidaan Human Acellular Vesselin (HAV) käyttöä aikuisilla, joilla on kaulan alapuolella oleva verisuonivaurio ja joille tehdään verisuonten korjaava leikkaus. Mukana on vartalon kohortti ja raajan kohortti. Kaikille koehenkilöille implantoidaan HAV välityssuoneena tai ohituksena käyttämällä tavallisia verisuonikirurgisia tekniikoita. Ohjausvartta ei ole.

Yksityiskohtainen kuvaus

Tämä on prospektiivinen, monikeskus, usean kohortin, ei-satunnaistettu vaiheen 2 tutkimus, johon osallistui jopa 40 aikuista potilasta, joilla on henkeä tai raajoja uhkaava verisuonitrauma, joka vaatii kirurgista korjausta. Tulee raajojen kohortti ja vartalon kohortti. Raajojen kohortti sisältää potilaat, jotka tarvitsevat ylä- tai alaraajojen sisällä olevan suonen korjaamista. Vartalon kohortti sisältää potilaat, jotka tarvitsevat rintakehän (lukuun ottamatta sydäntä), vatsan ja vatsakalvon suonten korjausta. Koehenkilöille implantoidaan Humacyte Human Acellular Vessel (HAV) välityssuoneena tai ohituksena käyttämällä tavallisia verisuonikirurgisia tekniikoita. Ohjausvartta ei ole.

Kunkin tutkimukseen osallistuvan aktiivisen tutkimuksen kesto on 36 kuukautta HAV-istutuksesta tai HAV:n epäonnistumiseen/poistoon/kuolemaan, jos aikaisemmin. Seuranta kuukauden 12 jälkeen sisältää tietojen keräämisen arvioinneista, jotka on suoritettu "standardin hoidon" rutiininomaisilla klinikkakäynneillä tai puhelimitse potilaan tai hänen lääkärinsä kanssa fyysisellä tarkastuksella ja ultraäänellä kuukausina 24 ja 36

Kliinisen tutkimuksen odotettu kokonaiskesto on 61 kuukautta (24 kuukautta ilmoittautumista ja 36 kuukautta seurantaa).

Kokeellinen: 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.

Tulosmittaus
Toimenpiteen kuvaus
Aikaikkuna
Primary Patency Rate of the Human Acellular Vessel (HAV) at Day 30 in the All HAV Group
Aikaikkuna: 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
Aikaikkuna: 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.

Time-to-event analysis estimating the long-term cumulative probabilities of patient survival through the 36-month follow-up period, evaluated across the pre-specified subgroup of participants enrolled with community-acquired vascular trauma restricted to the upper or lower extremities (n=54). To ensure precise efficacy evaluation within this clinical cohort, this specific analysis population excludes all study participants who presented with torso arterial trauma, as well as those treated for iatrogenic, hospital-acquired vascular injuries.. This metric reports the explicit Kaplan-Meier survival probability estimates and accompanying 95% Confidence Intervals calculated at the Month 36 milestones. Standard censoring rules apply to participants who died, withdrew early, or reached the data cutoff milestone without an event.
