Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Placement of an Inferior Vena Cava Filter involves being given a medicine to make the patient sleepy. The area where the Study Physician will make the puncture (small hole) in the neck will be cleaned with a skin sterilizing liquid. Next the treatment area will be numbed with medicine (similar to Novocain that you get at a dentist). A needle will be used to gain access to the vein and then a small tube with the device inside of it will be moved to the area in the vein where the Study Physician wants the device to be. The Study Physician will then put the device where it is going to stay and pull the small tube out. After the procedure the Study Physician will press on the area of the neck where the needle was until bleeding stops. This procedure will be completed once. The complete procedure will be less than 1 hour in duration. The medication used to numb the area will be different from the medication used to make the patient "sleepy". The protocol does not require specific medications to be used. The choice of the type and amount of medication will be up to the investigator's preference and per local guidelines. The device may be removed as soon as 5 days or may be permanent depending on the participant's condition.

Outcomes
Primary outcome [1] 288432 0
Verify the effectiveness and safety of the Veniti IVC Filter in accordance with the clinical guidelines published by the Society for Interventional Radiology (SIR) . The endpoint is clinical success (versus failure) at 6 months after implant or 1 month post retrieval, whichever occurs first, based on the definition provided by the SIR guidelines, as the absence of:
Procedure failure (assessed at the end of the implant procedure)
a) Subsequent pulmonary embolus
b) IVC occlusion
c) Filter embolization
Timepoint [1] 288432 0
Follow up for 24 months post implant or 1 month post retrieval whichever comes first
Secondary outcome [1] 300146 0
Secondary assessments include estimating the rate of retrieval success.
Timepoint [1] 300146 0
This will be completed at the time of retrieval if applicable. This is determined by asking the physician post retrieval how they felt the procedure went.
Secondary outcome [2] 300149 0
Assessing filter performance rate:
a) Filter migration
b) Filter fracture
c) Filter Tilt
Timepoint [2] 300149 0
Follow up for 24 months post implant or 1 month post retrieval whichever comes first.
These will be assessed by a venogram during placement, an x-ray, and a CT scan at the 6 month post device placement.
Secondary outcome [3] 300154 0
Secondary assessments include estimating the rate of device and procedure related adverse events
Timepoint [3] 300154 0
Adverse Events are collected throughout the duration of the subject's participation.

Key exclusion criteria
Potential subjects will be excluded from the study if any of the following conditions apply:

3)Known IVC transverse diameter at target implant site > 28 mm
4)Known obstructing abdominal mass or anatomy that is not suitable for infra-renal placement of IVC filter
5)Known duplication of IVC or left-sided IVC
6)Severe kyphosis or scoliosis
7)Known IVC thrombosis extending to renal veins, or renal or gonadal vein thrombosis

17) Simultaneously participating in another therapeutic drug or device clinical trial or has participated in such trial in the 30 days prior to enrollment
18) Investigator considers patient to be a poor candidate for the study or that including the patient may compromise the study, e.g., suspect patient may not comply with follow up procedures, concomitant conditions
19)Patient does not wish to consent to study or comply with study procedures, including possible 2 year follow up

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The potential particpants will be patients referred to Radiology for IVC filter placement. The trial option will be presented to the participant. If they qualify and wish to participate they will recieve the Veniti IVC filter. If they do not wish to participate or do not qualify they would recieve an off the shelf approved IVC filter.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
All subjects who wish to participate and who qualify will recieve the Veniti IVC filter.

Summary
Brief summary
The blockage of the vein leading to the lungs is usually caused by a blood clot coming from the legs. The device is a small metal cage that will be placed in the large vein (inferior vena cava) leading to the heart. The device is placed there to prevent clots from reaching the lungs. The study device is not approved for use in the prevention of reoccurring lung clots. Use of this product is considered investigational in Australia.
