Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The BREAST-AB Trial is a multi-center, randomized, double blind, placebo-controlled trial investigating the efficacy of local application of gentamicin, vancomycin and cefazolin in decreasing all-cause implant explantation after breast reconstruction.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The BREAST-AB Trial will include women undergoing breast reconstruction with implants. The objective is to determine the efficacy of local antibiotics in decreasing all-cause implant explantation. Participants will be randomized to local application of placebo or gentamicin, vancomycin and cefazolin in a saline solution onto the implant and the dissected breast pocket. All patients undergoing unilateral breast reconstruction will be randomized to the trial drug or placebo in a ratio of 1:1. All patients undergoing bilateral reconstruction will be randomized to the trial treatment on one of their breasts and placebo to the contralateral breast. A total number of 1274 of breasts undergoing breast reconstruction will be included in the trial.

Participants Caregivers Investigators Outcome Assessors
The trial will be double-blind so that the patients, site investigators and data monitors will be blinded to the allocation. Only the designated nurses and the members of the trial coordinating unit (who provide the randomization number and treatment allocation) are not blinded to the allocation. The unblinded persons will not in any way be part of the treatment, clinical evaluation of outcomes or data assessment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Irrigation of implants with sterile isotonic saline

The placebo solution will consist of 500 mL of sterile isotonic (9%) saline contained in a infusion bag.

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type OTHER

500 mL of sterile isotonic (9%) saline. The solution will be used to wash the dissected implant pocket and the implant prior to insertion in the implant pocket.

Irrigation of implants with a triple antibiotic solution

The antibiotic solution will contain 1000 mg vancomycin, 80 mg gentamicin and 1000 mg cefazolin in 500 mL sterile isotonic (9%) saline

Group Type EXPERIMENTAL

Gentamicin, Cefazolin and Vancomycin

Intervention Type DRUG

The antibiotic solution will contain 1000 mg vancomycin, 80 mg gentamicin and 1000 mg cefazolin in a 500 mL isotonic saline solution. The solution will be used to wash the dissected implant pocket and the implant prior to insertion in the implant pocket.
