About this study

Official title: Montage- Enhanced Sternal Closure to Accelerate Post-Operative Recovery

Post-operative recovery after cardiac surgery is influenced by early sternal bone stability. Traditional sternal closure of median sternotomy usually entails the use of 6-10 stainless steel wires. Augmenting sternal closure with techniques to enhance early bone stability should accelerate functional recovery from cardiac surgery thereby reducing post-operative pain, decreasing the need for narcotics, improving breathing and chest wall mechanics, stimulating early mobility and expediting hospital discharge.

This study is a randomized, single-centre, double-blind clinical study comparing the effects of Montage bone putty plus conventional wire closure vs conventional wire closure only on the post-operative recovery of cardiac surgery patients with full medial sternotomy.

Read the detailed description

Patients undergoing cardiac surgery who are participating in the study will be randomized to either conventional wire cerclage or conventional wire closure plus the use of Montage bone putty. Patients will be followed post-operatively Day 3, 5 and at discharge as well as weeks 2, 4, 6 and months 3, 6 and 12.

Each visit will include: Pain assessment, wound assessment, sternal assessment, analgesic/antibiotic use, spirometry testing, quality of life questionaries (EQ-5D/HAQ) and determination of any adverse events. Chest x-rays will done at discharge and 3, 6, and 12 months to look at sternal healing.

This pilot study will include a total of 65 patient (40 conventional + putty / 20 conventional/ 5 initial open label with putty).

What is being measured

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

  1. Recovery of Respiratory Function

    The recovery of pulmonary functional capacity as measured by the return of forced vital capacity (FVC) to 80% or greater of the pre-operative baseline FVC measurement.

    Measured: Intervention to 6 weeks post-operative

  2. Radiographic Sternal Integrity

    No radiographic evidence of bony instability as assessed through serial chest x-rays

    Measured: Intervention to 12 months post-operative

  3. Sternal Revision

    Absence of device (wire or Montage bone putty) removal, revision or reoperation occurring over first 12 months post-operative.

    Measured: Intervention to 12 months post-operative

Secondary outcomes (6)
  1. Post-operative Pain Assessment

    Severity of post-operative pain (survey score and analgesic use) comparing treatment vs control groups

    Measured: Baseline to 12 months post - operative.

  2. Rate of post-operative recovery

    Rate of post-operative recovery as measured by health related quality of life (EQ5D) standardized assessment tool

    Measured: Baseline to 12 months post-operative

  3. Rate of post-operative recovery

    Rate of post-operative recovery as measured by physical functioning (HAQ) standardized assessment tool

    Measured: Baseline to 12 months post-operative

  4. Sternal Wound Infections

    Frequency of sternal wound infections (superficial and deep) between groups

    Measured: Baseline to 12 months post-operative

  5. Pulmonary Complications

    Post-operative pulmonary complications between groups

    Measured: Baseline to 6 weeks post-operative

  6. Health Services resource usage

    To compare the burden of health services resource usage between groups (total cost estimate)

    Measured: Baseline to 12 months post-operative

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Montage bone putty and Conventional Sternal Closure in people with Sternal Closure, run by University of Calgary at 1 site in Canada.

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 5 inclusion and 17 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 28 Sep 2021. 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 Canada. 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.

What does this 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.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recovery of Respiratory Function (time frame: Intervention to 6 weeks post-operative). The study lists 3 primary outcomes in all. 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 NCT03365843, which also lists 1 linked publication.

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 28 Sep 2021.
