About this study

Official title: Fibrin Sealant to Reduce Postoperative Bleeding After Blepharoplasty

This study is looking at the effect of Tisseel in eyelid surgery. Fibrin sealants (Tisseel) cause there to be less bleeding during surgery. Surgeons have used Tisseel for over two decades to reduce bruising. Ophthalmologists use it during surgery. Yet, there are no studies confirming the effect of Tisseel during eyelid surgery. Unpublished work suggests that it is effective in decreasing postoperative bruising. This study will confirm the effect of Tisseel on postoperative bruising in blepharoplasty.

Read the detailed description

The study is designed as a superiority randomized control trial. Tisseel will be used for hemostasis during the closure of one blepharoplasty incision. The side to receive Tisseel will be determined using a random number generator. After application of topical Tisseel, both eyelids will undergo standard blepharoplasty closure techniques. Pressure will be placed on both upper eyelids to mask the patient as to what side received the Tisseel.

Postoperatively, patients will take photographs on postoperative days 1, 3, 7. Photographs with poor quality not allowing accurate assessment will not be scored and that visit will not be included in the study. The photographs will be assessed by two masked ophthalmic surgeons who will rate the degree of postoperative bruising. Upper and lower eyelids of each patient will be evaluated separately. Observers will assess each side for ecchymosis using a 10-point Likert scale (1, none; 10, severe) on postoperative days 1, 3 and 7.

Given a blepharoplasty costs the healthcare system approximately $950 Canadian dollars, a vial of Tisseel ($160) would add approximately 17% to the cost (160/942.43 = 16.97%). Therefore, a 17% percent margin of superiority was used in power calculations to determine statistical efficacy of the intervention.

A power calculation for a randomized control superiority trial was performed. A 17% percent margin of superiority was used in power calculations. These variable were used to calculate for a dichotomous outcome superiority trial. The calculated sample size was calculated to be 27 in each group.

Tisseel is made from human plasma and may therefore contain infectious agents, such as viruses, that can cause disease. With over two decades of use, there has never been a reported case of hepatitis (HAV, HBV, HCV) or human immunodeficiency virus (HIV) transmission. However, Tisseel used during thoracic surgery has been associated with increased seropositivity for parvovirus B19. Although there were no complications associations with the parvovirus B19 infection observed, infection with parvo B19 can theoretically cause anemia or arthralgias, fifth disease in children, miscarriage, or rash. All patients who would be at risk of complications from such an infection were excluded.

Research is ongoing, despite the continuation of the COVID-19 pandemic. Postoperative photographs taken by the patients are used to minimize contact during care.

What participants receive

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

  • TisseelBiological

    Intraoperatively, the intervention side will receive topical administration of Tisseel to the blepharoplasty incision. A 2mL syringe of Tisseel product will be used as per the product monograph for an area of < 8cm2. There will be no variation in surgical counselling or technique, with the exception of the use of Tisseel in one eyelid closure. Both eyelids will otherwise receive standard blepharoplasty surgical techniques. There will be no monitoring of compliance necessary, given the Tisseel will be utilized intraoperatively.

What is being measured

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

  1. Bruising as defined by masked observers using a 10-point Likert scale.

    Postoperative photographs will be assessed by two masked ophthalmic surgeons who will rate the degree of postoperative bruising. Upper and lower eyelids of each patient will be evaluated separately. Observers will assess each side for ecchymosis using a 10-point Likert scale (1, none; 10, severe) on postoperative days 1, 3 and 7.

    Measured: 1 week

Model description
Each participant in the study will receive a topical application of fibrin sealant (Tisseel) in one of their upper eyelid eyelid blepharoplasty closures in addition to standard blepharoplasty closure techniques. The other eyelid will receive standard blepharoplasty closure techniques alone, without fibrin sealant. Both sides will receive 1 minute of pressure, after application of Tisseel, to mask which side received treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Tisseel in people with Blepharoptosis and Ecchymosis; Eyelid, run by University of Calgary.

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 1 inclusion and 6 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 3 May 2022. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 David Plemel, MD ((403) 255-5561, dplemel@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Bruising as defined by masked observers using a 10-point Likert scale. (time frame: 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05358977, which also lists 7 linked publications.

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 3 May 2022.
