NCT06453642

Brief Summary

The objective of this study is to evaluate the safety and effectiveness of the GPX® Embolic Device when used as indicated for embolization requiring distal vessel penetration in 114 subjects in up to 25 investigational sites in the USA, New Zealand, and Canada.

Outcome Measures

Primary Outcomes (3)

  • Freedom from major adverse events (MAEs)

    MAEs are defined as: * Nontarget embolization with ischemia in an unintended anatomical area * Systemic allergic and/or toxic reaction to the GPX Embolic Device * Catheter entrapment and/or breakage * Culture-proven abscess in target organ/tissue * Embolization-related death

    Index procedure through 30-day follow-up

  • Single binomial proportion of successful delivery of the GPX Embolic Device to the target vessel embolization site(s)

    Determined by the investigator at the time of enrollment

    During procedure

  • Single binomial proportion of successful occlusion of flow immediately beyond the target vessel embolization site(s)

    Determined by the core lab via comparison of the pre- and final post-embolization images

    End of procedure

Secondary Outcomes (3)

  • Occurrence of device-related adverse events (AE) through 30 days post-index procedure

    30-day follow-up

  • Occurrence of adjunctive embolization agent usage during the embolization procedure

    End of procedure

  • Occurrence of catheter occlusion due to the GPX Embolic Material

    End of procedure

Study Arms (1)

GPX® Embolic Device

EXPERIMENTAL
Device: GPX® Embolic Device

Interventions

Treatment includes distal embolization in the peripheral vasculature of vascular tumors, renal embolization, and portal vein branches

GPX® Embolic Device

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥18 years on the date of consent
  • Expected post-procedural lifespan of at least 30 days, in the opinion of the investigator, to allow for participation in all follow-up visits
  • Presents with need for peripheral embolization where there is a desire for distal vessel bed penetration including:
  • Vascular tumors (e.g., renal angiomyolipoma, renal cell carcinoma, bone tumors, bleeding tumors, and other vascular tumors)
  • Renal embolization
  • Portal vein branches
  • Informed consent granted by the patient or legally authorized representative
  • Willing and able to comply with the protocol-specified procedures and assessments

You may not qualify if:

  • Requires embolization for any of the following applications: a) Neurovasculature b) Coronary vasculature c) Hemorrhage due to trauma d) Non-tumoral focal/active bleeding sites (e.g., gastrointestinal tract, urinary tract, lung) e) Veins other than portal vein f) Aneurysms g) Endoleaks h) Vascular malformations i) Vessels for flow redistribution
  • Has undergone an embolization procedure within 30 days prior to consent
  • Presents with need for embolization where the risk of clinically significant infarction outweighs the benefit of distal penetration (e.g., gastrointestinal, uterine)
  • Embolization target is only intended for temporary occlusion (e.g., bioresorbable biologic embolic agents)
  • Known allergy or hypersensitivity to contrast media that cannot be adequately medicated
  • Pregnant, planning to become pregnant during the study period, or breastfeeding
  • Unresolved systemic infection or localized infection in the targeted region
  • Pre-operative laboratory tests and/or physical examination indicate abnormal results, which, in the opinion of the investigator, would clinically confound the study primary endpoints
  • Existing medical condition which, in the opinion of the investigator, may cause the subject to be intolerant of an occlusion procedure or non-compliant with the protocol or may confound the data interpretation
  • Subject is participating in another device, drug, or procedure clinical investigation and has not completed the study treatment or the other investigation clinically interferes with the endpoints of this study (post-approval registries are allowed as long as the investigator determines there is no clinical interference with study endpoints)
  • Vulnerable subject populations (e.g., incarcerated or cognitively challenged adults) 12. Patients with drug or alcohol dependency (within 6 months prior to study entry) that, in the opinion of the investigator, would interfere with safe delivery of the study treatment or with the interpretation of study results
  • \. Presence of persistent, flow-limiting vasospasm that is not responsive to chemical or mechanical interventions 14. Presence of collateral pathways potentially endangering normal territories during embolization 15. Blood flow precludes safe delivery of embolic material (e.g., arteriovenous shunting or high, unpredictable flow exists) 16. Anatomy that precludes advancement of the delivery device to target vessel embolization site or delivery of embolic material 17. Dissection in the target vessel 18. The delivery device has already been used with an ionic contrast agent (e.g., Conray® (iothalamate meglumine injection USP 60%), Guerbet)
