Vascular Graft Infection clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Siderophores for Imaging Infection Using 68Ga-DFO

GaDFO

Start date: March 15, 2022
Phase:
Study type: Observational

This is a single center pilot study involving a single study visit for participants, with remote follow up data collected at 24 hours. Follow up at 3 months and 6 months later occurs as standard of care. The purpose of the study is to find out if a new type of imaging tracer (68Ga-DFO) can be used to show infection in patients with vascular grafts using PET/CT scans. These infections may be associated with significant ill health and mortality and can be difficult to diagnose. Effective treatments can require major surgery and long-term antibiotic therapy which may not be well tolerated nor feasible. Development of new imaging tracers that could detect bacteria causing graft infections with PET-CT scanners has great potential to benefit patients being considered for vascular surgery. A PET-CT scan combines images from a CT (Computerised Tomography) scan and a PET (Positron Emission Tomography) scan. The CT scan takes a series of X-rays across the organs inside the body. The PET scan uses a mildly radioactive tracer to show up areas of activity inside the body. The 68Ga-DFO tracer mimics particles that bacteria make to take up iron from the body to help them grow. The investigators hope this new tracer will go to areas where bacteria are causing infection and tell if the graft is infected. The investigators hope this type of tracer could be a better way to show infection than the tests currently used to diagnose infection.
