About this study

Official title: Safety and Efficacy Study of FemFlow Drug-Eluting Peripheral Balloon Catheter for Lesions With Femoral-popliteal Artery Stenosis or Occlusion: a Prospective, Multi-centre, Objective Performance Criteria Clinical Trial.

A prospective, multi-centre, objective performance criteria clinical trial to evaluate the safety and efficacy of FemFlow Drug-Eluting Peripheral Balloon Catheter manufactured by Lifetech Scientific (Shenzhen) Co., LTD. for lesions with femoropopliteal artery stenosis or occlusion.

Read the detailed description

This study is a prospective, multi-centre, single-group target value clinical study. Taking the patency rate at 12 months after operation as the primary evaluation index and taking target vascular cavity loss rate at 6 months postoperatively, Rutherford Classification at 12 months postoperatively, the ankle/brachial index (ABI), revascularization rate of target lesions, revascularization rate of target vessels, operating success rate and success rate of surgery as the secondary evaluation indexes to evaluate the efficacy of FemFlow Drug-Eluting Peripheral Balloon Catheter manufactured by Lifetech Scientific (Shenzhen) Co., LTD. for lesions with femoropopliteal artery stenosis or occlusion. Taking the incidence of major adverse events (MAE), adverse events (AE) and instrument defects occurred through the entire trail as the evaluation indexes to evaluate the safety of FemFlow Drug-Eluting Peripheral Balloon Catheter manufactured by Lifetech Scientific (Shenzhen) Company for lesions with femoropopliteal artery stenosis or occlusion. According to statistical hypothesis and sample size calculation, the sample size of this clinical trial was 208 cases. All subjects were followed up 1 month, 6 months and 12 months after treatment with a FemFlow Drug-Eluting Peripheral Balloon Catheter, and data on efficacy and safety were collected. All relevant clinical data are managed and analyzed by the professional data management centre and the statistical centre. End-point events of clinical trials are determined by a specially established third party.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FemFlow Drug-Eluting Peripheral Balloon CatheterDevice

    Medical devices will be applied to the enrolled subjects. The arterial pathway was established, followed by lower limb arteriography, and the auxiliary equipment was selected according to the stenosis of the subject's target lesions, followed by pre-dilation. Patients with residual stenosis ≤70% after pre-dilation and suitable for simple balloon dilation catheter treatment can be enrolled. Select the appropriate size of the experimental drug balloon for expansion, then radiography was used to observe the expansion effect, if necessary, multiple expansion can be conducted, and finally withdraw the instrument and suture the puncture point.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patency rate of the first phase

    Target vessel patency is defined as all target lesion lumen stenosis of the target vessel ≤50%. Doppler ultrasonography showed that the peak systolic velocity ratio (PSVR) was ≤ 2.4, which could be considered as the target lesion stenosis ≤50%.

    Measured: Postoperative 30 ± 7days

Secondary outcomes (7)
  1. Target vascular cavity loss rate.

    Target vascular cavity loss rate (LLL) is defined as the value of the minimum diameter reduction in the segment of target lesions after surgery. Evaluation was performed by lower limb artery digital subtraction angiography (DSA) examination.

    Measured: Postoperative 180 ± 28days

  2. Rutherford Classification.

    Stage 0 - Asymptomatic Stage 1 - Mild claudication Stage 2 - Moderate claudication - The distance that delineates mild, moderate and severe claudication is not specified in the Rutherford classification, but is mentioned in the Fontaine classification as 200 meters.

    Stage 3 - Severe claudication Stage 4 - Rest pain Stage 5 - Ischemic ulceration not exceeding ulcer of the digits of the foot Stage 6 - Severe ischemic ulcers or frank gangrene

    Measured: Postoperative 30 ± 7days

  3. Ankle/brachial index (ABI)

    The ankle/brachial index (ABI) is defined as the systolic pressure ratio of the tibialis posterior artery or tibialis anterior artery of the affected limb to the ipsilateral brachial artery when the subject is lying flat.

    Measured: Postoperative 30 ± 7days

  4. Revascularization rate of target lesions

    Target lesion revascularization was defined as finding target lesion embolism or restenosis (stenosis in diameter of >50%) during follow-up, and additional intervention was required according to clinical symptoms.

    Measured: Postoperative 30 ± 7days

  5. Revascularization rate of target vessels

    Target lesion revascularization was defined as finding target vessels embolism or restenosis (stenosis in diameter of >50%) during follow-up, and additional intervention was required according to clinical symptoms.

    Measured: Postoperative 30 ± 7days

  6. Operating success rate

    Successful operation is defined as in the course of operation, the peripheral balloon catheter can reach the location of the disease and successfully expand, fail to rupture the balloon, and successfully withdraw.

    Measured: Intraoperative

  7. Success rate of surgery

    The success of surgery is defined as the residual stenosis rate ≤30% during the operation.

    Measured: Intraoperative

Questions about this trial

What is this clinical trial studying?

A study testing FemFlow Drug-Eluting Peripheral Balloon Catheter in people with Femoral Artery Stenosis and Femoral Artery Occlusion, run by Lifetech Scientific (Shenzhen) Co., Ltd. at 18 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ying Xia (+86 13760184511, xiaying@lifetechmed.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patency rate of the first phase (time frame: Postoperative 30 ± 7days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Feb 2020.
