Humacyte Human Acellular Vessel (HAV) vaszkuláris traumában szenvedő betegeknél

2026. július 1. frissítette: Humacyte, Inc.

2. fázisú vizsgálat a Humacyte humán sejtes erének biztonságának és hatékonyságának értékelésére a vaszkuláris pótláshoz vagy rekonstrukcióhoz életet vagy végtagot veszélyeztető érsérülésben szenvedő betegeknél

Ez a tanulmány a Human Acellular Vessel (HAV) alkalmazását értékeli olyan felnőtteknél, akiknek nyak alatti ér traumája van, és érrekonstrukciós műtéten esnek át. Lesz törzs és végtag kohorsz. Minden alanynak HAV-t ültetnek be interpozíciós érként vagy bypassként, standard érsebészeti technikák alkalmazásával. Nincs vezérlőkar.

Részletes leírás

Ez egy prospektív, többközpontú, több kohorszos, nem randomizált, 2. fázisú vizsgálat legfeljebb 40, életet vagy végtagot veszélyeztető, műtéti javítást igénylő érsérülésben szenvedő felnőtt beteg bevonásával. Lesz egy végtag kohorsz és egy törzs kohorsz. A végtagok csoportjába azok a betegek tartoznak, akiknek a felső vagy alsó végtagon lévő ér javítására van szükségük. A törzs kohorszba tartoznak azok a betegek, akiknél a mellkasban (kivéve a szívben), a hasban és a retroperitoneumban lévő ereket kell helyreállítani. Az alanyokba Humacyte Human Acellular Vessel-t (HAV) ültetnek be interpozíciós érként vagy bypassként standard érsebészeti technikák alkalmazásával. Nincs vezérlőkar.

Az aktív vizsgálat időtartama minden vizsgálati résztvevő esetében a HAV beültetésétől számított 36 hónap, vagy a HAV sikertelenségéig/eltávolításáig/haláláig, ha korábban. A 12. hónap utáni nyomon követés magában foglalja a „standard ellátás” rutin klinikai látogatások során végzett értékelésekkel kapcsolatos információk rögzítését, vagy telefonos nyomon követést a beteggel vagy orvosával fizikális vizsgálattal és ultrahanggal a 24. és 36. hónapban.

A klinikai vizsgálat teljes várható időtartama 61 hónap (24 hónap a beiratkozástól és 36 hónapos követés).

Kísérleti: 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.
Biológiai: 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.

Időkeret: 36 months from time of implantation
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.
