Recruiting PHASE4 Staphylococcus Aureus Bacteremia

New treatment option for Staphylococcus Aureus Bacteremia

Official title Staphylococcus Aureus Network Adaptive Platform Trial

ClinicalTrials.gov ID: NCT05137119

What this study is testing

What is Cefazolin?

Cefazolin is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for staphylococcus aureus bacteremia.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The Staphylococcus aureus Network Adaptive Platform (SNAP) trial is an International Multi-Centered Randomised Adaptive Platform Clinical Trial to evaluate a range of interventions to reduce mortality for patients with Staphylococcus Aureus bacteraemia (SAB).
  • Phase 4: studies an already-approved treatment
  • Which group you join is decided by chance.

  • Afebrile (\<37.8°C) for the past 72 hours (at time of judging eligibility)
  • Site Principal Investigator has determined that source control is adequate Exclusion Criteria: When judging eligibility at platform Day 7 (+/- 2 days) and at Day 14 (+/- 2 days), exclusion criteria are:
  • Adherence to oral agents unlikely (as judged by site PI in consultation with the treating team)
  • Unreliable gastrointestinal absorption (e.g. vomiting, diarrhoea, nil by mouth, anatomical reasons)
  • There are no appropriate oral antibiotics due to contraindications, drug availability, or antibiotic resistance
  • Ongoing IV therapy unsuitable e.g. no IV access

  • Patient no longer willing to participate in domain In the lead-up to judging eligibility, it may be helpful to discuss with the patient the potential for continued IV treatment versus oral switch, to allow hospital...
  • Clinical team deems that sufficient duration of antibiotic therapy has already been provided Exclusions when judging eligibility for early oral switch at trial Day 7 (+/- 2 days):
  • Presence of prosthetic cardiac valve, pacemaker or other intracardiac implant
  • Presence of intravascular clot, graft, or other intravascular prosthetic material Intravascular clot excludes superficial peripheral IV line-related thrombophlebitis. Intravascular prosthetic material excludes coronary...

  • Presence of other intracardiac abnormalities felt to put patient at increased risk of endocarditis (e.g., bicuspid aortic valve) PET/CT DOMAIN Inclusion Criteria:

  • Patient is accessible for PET/CT - a patient is considered accessible if the site team are able to access the participant medical records, arrange for a PET/CT scan for the patient, and discuss this domain with the...
  • Pregnant - patients of childbearing potential should be assessed for pregnancy status and a pregnancy test performed (if not performed within the past 10 days)
  • Currently breastfeeding
  • \< 18 years of age
  • Patient has had PET/CT in the past 7 days
  • Patient needs PET/CT in the next 7 days (in the opinion of the clinical team, at the time of eligibility assessment)
  • Clinically unstable for PET/CT (as judged by the treating clinical team, taking into account need for organ support (including inotropes) and capacity to lie flat for the PET/CT)
  • Contraindication to PET/CT (e.g., claustrophobia, persistently elevated blood sugar levels [\>12.5mmol/L] that cannot be corrected).
  • Patient no longer willing to participate in the domain - in the days leading up to judging eligibility, it may be helpful to discuss with the patient the potential for PET/CT vs no PET/CT to allow imaging planning
  • Clinician deems participation in this domain is not in the patient's best interests

The study team makes the final eligibility decision.
