Brief Summary

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

Local application of antibiotics directly to the traumatic wound is a promising strategy for the prevention of infection after open tibia fractures, which are a significant source of disease burden globally, particularly in low-income countries. This pilot study aims to assess feasibility of a randomized controlled trial to measure the effect of locally applied gentamicin on risk of infection for open tibial fractures in Tanzania. If proven effective, local gentamicin would be a highly cost-effective strategy to reduce complications and disability from open tibial fractures that could impact care in both high- and low-income countries.

Detailed Description

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

This pilot study is being conducted in Dar es Salaam, Tanzania to assess the feasibility of a masked, placebo-controlled, randomized trial to compare local gentamicin injection to saline injection in open tibial shaft fractures. The study will enroll patients within 1 week of injury. The active or placebo agent will be administered during the initial surgical debridement based on a web-based randomization tool. Patients will be followed for 1 year after surgery to assess for the occurrence of fracture-related infection (FRI), a consensus definition of infection after open fracture or insertion of internal fixation to treat fracture. Additional clinical and economic endpoints will also be measured.

Depending on the outcome of the feasibility study, we may undertake a definitive trial to test the effectiveness of local gentamicin to prevent FRI. If proven effective, local gentamicin would impact the clinical care of open fracture patients both in Tanzania and likely in high-income settings as well. These data will also deepen the understanding of the clinical and economic impact of FRI in open fracture populations.

Patients will receive gentamicin in saline solution or placebo saline injection while under anesthesia during the index surgery. Only the local research pharmacist, the UCSF clinical trial manager, and the DSMC will be unmasked.

Study Groups

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

gentamicin injection at fracture site

Subjects with an open tibia fracture who receive gentamicin in saline solution administered after closure at the time of initial debridement.

Group Type EXPERIMENTAL

local gentamicin injection

Intervention Type DRUG

Treatment includes debridement and administration of the local antibiotic which will consist of 80mg of liquid gentamicin diluted in 40mL normal saline injected after inserting a 22 gauge needle down to bone after wound closure. The injection will continue until either all 40cc are injected or there is fluid extravasation from the wound.

placebo saline injection at fracture site

Subjects with an open tibia fracture who receive placebo saline solution administered after closure at the time of initial debridement.

Group Type PLACEBO_COMPARATOR

placebo saline injection

Intervention Type DRUG

Treatment includes debridement and administration of the local antibiotic which will consist of 40mL normal saline injected after inserting a 22 gauge needle down to bone after wound closure. The injection will continue until either all 40cc are injected or there is fluid extravasation from the wound.
