Trial summary

Background: Mastectomy flap necrosis (MFN) is a common complication that affects recovery, reconstructive success and aesthetic outcome. Nitroglycerin (NTG) ointment is a potent topical vasodilator that increases local blood flow by dilating arteries and veins without altering the ratio of pre- to post-capillary… Read more about this study

About this study

Background:

Mastectomy flap necrosis (MFN) is a common complication that affects recovery, reconstructive success and aesthetic outcome. Nitroglycerin (NTG) ointment is a potent topical vasodilator that increases local blood flow by dilating arteries and veins without altering the ratio of pre- to post-capillary resistance. There are no studies that evaluate whether the application of NTG ointment in patients undergoing Skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) and immediate reconstruction decreases the rate of mastectomy flap necrosis.

Objective:

To evaluate if the post-operative application of NTG ointment improve rates of MFN in patients undergoing SSM or NSM with immediate breast reconstruction compared to patients receiving placebo.

Hypothesis:

In patients undergoing SSM and immediate breast reconstruction there will be a decrease in the rate of MFN in those who receive NTG ointment compared to those who receive placebo.

Being tested
nitroglycerin ointment, Polysporin ointment

What participants receive

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

  • nitroglycerin ointmentDrug

    Nitroglycerin ointment will be applied to mastectomy skin flaps at the end of surgery. A maximum of 7.5cm strip of 2% Nitroglycerin ointment will be applied (equivalent to a maximal dose of 45mg)

  • Polysporin ointmentDrug

    Polysporin ointment will be applied as the control ointment on the mastectomy flap skin at the end of surgery. A maximum of 7.5cm strip of ointment will be applied to the skin.

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 3 inclusion and 19 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: finished, as of the sponsor's last update on 10 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Mastectomy Flap Necrosis (time frame: 1 month post operative). 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 NCT01608880, which also lists 19 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 10 Sep 2014.
