Study summary

This study is a prospective, multicenter, single-arm post-market clinical study to evaluate the GORE® VIABAHN® FORTEGRA Venous Stent in real-world use.

Read the detailed description

A maximum of 35 clinical investigative sites in the U.S. will participate in this study. One hundred and fifty subjects are intended to be implanted with the GORE® VIABAHN® FORTEGRA Venous Stent in this study, with a limit of 30 treated subjects per site. Subjects will be evaluated through hospital discharge and return for follow-up visits at 1, 6, 12, 24, and 36 months post-treatment.

Eligibility criteria

Preoperative Inclusion Criteria:

  • Presence of a lesion necessitating treatment with the GORE® VIABAHN® FORTEGRA Venous Stent, as previously determined by an investigator/sub-investigator.
  • Patient is at least 18 years of age.
  • Patient is willing and able to comply with all follow-up evaluations as well as any required medication or compression regimen.
  • Patient is able to provide informed consent themself.

Intraoperative Inclusion Criteria:

  • Patient can accommodate an appropriately sized GORE® VIABAHN® FORTEGRA Venous Stent as per reference vessel diameter (see IFU), as determined by intraoperative IVUS post pre-dilation.
  • Patient must have appropriate access vessels to accommodate the delivery sheath for the selected device size.
  • Patient has adequate landing zones free from significant disease requiring treatment beyond the proximal and distal margins of the lesion.
  • Patient has adequate inflow/outflow to/from the target lesion(s), per investigator/sub- investigator discretion.
  • Lesion can be traversed with a guidewire.

Intraoperative Exclusion Criteria:

  • Patient is contraindicated for treatment with the GORE® VIABAHN® FORTEGRA Venous Stent according to the IFU.

What researchers measure

Primary outcomes

  1. Primary effectiveness as assessed by primary patency

    Rate of subjects with primary patency as confirmed by imaging and adverse events

    Time frame: 12 months

  2. Primary safety as assessed by SAEs

    Rate of subjects with freedom from device- or index procedure-related SAEs

    Time frame: 30 days

Secondary outcomes

  1. Rate of subjects with primary patency as confirmed by imaging and adverse events

    Rate of subjects with freedom from both: * stent occlusion due to restenosis or thrombosis as confirmed with imaging, and * clinically driven target lesion revascularization as confirmed with imaging and adverse events

    Time frame: 36 months

  2. Rate of subjects with secondary patency as confirmed by imaging and site-reported device abandonment

    Freedom from permanent loss of blood flow through the device, regardless of reintervention

    Time frame: 36 months

  3. Rate of subjects with clinically driven target lesion revascularization as confirmed by imaging and adverse events

    Rate of subjects with Repeat endovascular procedures (e.g., PTA, stenting, thrombectomy/thrombolysis) to restore flow, performed within the margins of the study devices due to ≥50% restenosis of the target lesion as measured via imaging AND the failure to improve or recurrence of symptoms present at baseline, or the onset of new symptoms related to the target lesion

    Time frame: 36 months

  4. Number of subjects with stent embolization as confirmed by adverse events and imaging

    Number of subjects with stent embolization

    Time frame: 12 months

  5. Number of subjects with device- or index procedure-related death as confirmed with adverse events

    Number of subjects with device- or index procedure-related death

    Time frame: 30 days

  6. Number of subjects with clinically significant pulmonary embolism as confirmed with imaging and adverse events

    Number of subjects with clinically significant pulmonary embolism as confirmed via CTA

    Time frame: 30 days

  7. Number of subjects with device- or index procedure-related vascular injury as confirmed with adverse events

    Number of subjects with device- or index procedure-related vascular injury requiring surgical or endovascular intervention

    Time frame: 30 days

  8. Number of subjects with device- or index procedure-related major bleeding events as confirmed with adverse events

    Number of subjects with device- or index procedure-related major bleeding events

    Time frame: 30 days

  9. 5 Level EuroQol-5 Dimension (EQ-5D-5L)

    Change in 5 Level EuroQol-5 Dimension (EQ-5D-5L) Measurement through 36-month follow-up compared to baseline prior to treatment

    Time frame: 36 months

  10. Technical success

    Number of subjects with successful delivery and deployment of the stent to the intended location

    Time frame: Index procedure (post-op day 0)

  11. Lesion success

    Number of subjects with evidence of ≤50% residual stenosis at the conclusion of the index procedure as measured by IVUS or contrast angiography

    Time frame: Index procedure (post-op day 0)
