About this study

Official title: Efficacy of Post-FESS Implantation of Composite Removable Sinus Stent System to Prevent Post-Operative Complications and Revision Surgery

This is a randomized controlled first in man study. Study purpose is to assess safety and efficacy of Composite Removable Stent Composite Stent implantation post-endoscopic sinus surgery in terms of:

  • Sinus tissue adhesions
  • Middle turbinate lateralization into nasal septum i.e. postoperative opening reduction
  • Inflammation
Read the detailed description

The purpose of this study is to assess Composite Removable Sinus Stent safety and efficacy implantation following FESS surgery compared to standard of care.

At first pilot stage, 3-6 patients will be enrolled to this study. At 2nd stage 19-27 additional patients will be enrolled to this study for statistical assurance.

In study group patients will undergo post-FESS bilateral implantation of Composite Removable Sinus Stent into ethmoid sinus under same anesthesia. Stent is inserted upon low pressure balloon catheter. After reaching target position balloon is inflated and stent deployed and secured. Balloon catheter is deflated and removed. Stent implanted for 14-28-day time period (depending on healing process and therapeutic effect). The stent will be removed upon balloon catheter or using medical grasper, following cooling and self-crimping.

In control group patients will undergo post-FESS bilateral tampon placement into middle meatus as standard of care. Tampon will be removed at day 2-3 post surgery.

Patients in pilot study group (group 1) scheduled for 6 follow up visits at 1,2,3,4,6 and 12 weeks after implantation.

Patients in study group (group 2) scheduled for 4 follow up visits at 2, 4, 6 and 12 weeks after implantation.

Patients in control group (group 3) scheduled for 3 follow up visits at 2, 6 and 12 weeks after surgery. All groups scheduled for tampon removal at day 2 - 3 after ESS surgery (if nessecery) .

During follow up visits patients will be examined for:

  • Endoscopic examination of the surgical cavity to assess inflammation, MT position, adhesions and polyposis.
  • Inflammation VAS anchored as o=none and 10cm=severe (significant erythema and edema and/or hypertrophy, and/or polypoid change.
  • Adhesions graded at 5-point scale as none, small but not obstructing, obstructing but easily separated, dense and separation is difficult, severe with complete MT lateralization into lateral nasal wall.
  • MT position graded at 4-point scale as medialized, normal, partially lateralized, and lateralized.
  • SNOT - 22 score - taken prior to FESS and at 12 weeks follow up.
  • Pain questioner - taken at tampon removal day for group 3 and at stent removal day for groups 1 and 2.

Stent will be removed between 14 and 28-day implantation, during self-crimp procedure induced by cold saline wash and safely pulled out. Stent removal performed after adrenaline-lidocaine administration for minimization of bleeding.

Study Discontinuation

  • Patient severe inflammation or pain associated with the stent
  • Patient nasal trauma.
  • Stent migration
  • Nitinol struts exposure as reason for granulation process initiation
Being tested
Composite Removable Sinus Stent, adrenaline-lidocaine, cold saline wash

What participants receive

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

  • Composite Removable Sinus StentDevice

    Post-FESS bilateral implantation of sinus stent into middle meatus. Nasal tampon will be placed to stop bleeding. Stent will be removed after 14 - 28-day implantation, during self-crimp procedure induced by cold saline flush and safely pulled out. During implantation period patients will be examined endoscopically for inflammation, adhesions and middle turbinate position.

  • adrenaline-lidocaineDrug

    adrenaline - lidocaine administration to minimize bleeding prior to stent removal (group 1 and group 2)

  • cold saline washProcedure or surgery

    nasal wash with cold saline prior to stent removal, to induce stent self-crimping.

pilot study group 1ExperimentalPatients in pilot study group 1 will undergo post-FESS bilateral implantation of Composite Removable Sinus Stent into middle meatus. Nasal tampon will be placed to stop bleeding if necessary. Patients in pilot study group scheduled for 6 follow up visits at 1,2,3,4,6 and 12 weeks after implantation and for tampon removal at day 2 - 3 after FESS surgery. Stent will be removed between 14 and 28-day implantation. Before removal adrenaline - lidocaine administration will be used locally to minimize bleeding and cold saline wash applied to induce stent crimping.

Frontal tampon will be placed to stop bleeding. Patients in control group scheduled for 3 follow up visits at 2, 6 and 12 weeks after surgery and for tampon removal at day 2 - 3 after FESS surgery.

What is being measured

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

  1. Composite Removable Sinus Stent efficacy compared to standard of care

    The primary objective of this study is to assess Composite Removable Stent efficacy following FESS surgery compared to standard of care, in terms of inflammation, adhesion s, middle turbinate position, and patient symptoms improvement assessed by SNOT-22 questioner.

    Measured: 12 weeks

Secondary outcomes (1)
  1. Pain associated with Composite Stent removal vs. standard of care removal

    The secondary objective is to assess patients pain associated with Composite Stent removal vs. tampon removal assessed using pain questioner filled in at tampon removal and stent removal days.

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Composite Removable Sinus Stent, adrenaline-lidocaine and cold saline wash in people with Chronic Sinusitis, run by STS Medical at 1 site in Israel.

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 9 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 2 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. 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 Miriam Sror (+972-54-7387188, j.flomen@ststent.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite Removable Sinus Stent efficacy compared to standard of care (time frame: 12 weeks). 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 2 May 2017.
