Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Efficacy, Therapy
To examine the effect on all-cause mortality at 90 days of a range of interventions in patients with SAB
Secondary objectives 1
- Examining the effect of a range of interventions on several secondary endpoints including mortality, hospital length of stay, treatment failure, treatment complications, and healthcare costs.
Conditions and MedDRA coding
Staphylococcus aureus bacteremia
Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 2
- Staphylococcus aureus complex grown from ≥1 blood culture
- Admitted to a participating hospital at the time of eligibility assessment (OR if patient has died, they were admitted to this site anytime from the time of blood culture collection until the time of eligibility assessment)
Exclusion criteria 8
- Time of anticipated platform entry is greater than 72 hours post collection of the index blood culture
- Polymicrobial bacteraemia, defined as more than one organism (at species level) in the index blood cultures OR in any subsequent blood culture reported between the collection of the index blood culture and platform eligibility assessment, excluding those organisms judged to be contaminants by either the microbiology laboratory or treating clinician
- Known previous participation in the randomised SNAP platform
- Known positive blood culture for S. aureus (of the same silo: PSSA, MSSA or MRSA) between 72 hours and 180 days prior to the time of eligibility assessment
- Treating team deems enrolment in the study is not in the best interest of the patient
- Treating team believes that death is imminent and inevitable
- Patient is for end-of-life care and antibiotic treatment is considered not appropriate
- Patient has died since the collection of the index blood culture
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- all-cause mortality at 90 days after platform entry
Secondary endpoints 15
- All-cause mortality at 14, 28 and 42 days after platform entry
- Duration of survival censored at 90 days after platform entry
- Length of stay of acute index inpatient hospitalisation for those surviving until discharge from acute inpatient facilities (excluding HITH/COPAT/OPAT/rehab), measured from platform entry to discharge from acute inpatient facilities, truncated at 90 days after platform entry.
- Length of stay of total index hospitalisation for those surviving until hospital discharge (including HITH/COPAT/OPAT/rehab), measured from platform entry to discharge from total index hospitalisation, truncated at 90 days after platform entry.
- Time to being discharged alive from the total index hospitalisation (including HITH/COPAT/OPAT/rehab), measured from platform entry to discharge from total index hospitalisation, truncated at 90 days after platform entry (and all deaths within 90 days will be considered ’90 days’).
- Microbiological treatment failure defined as positive sterile site culture for S. aureus [of the same silo as the index isolate] between 14 and 90 days after platform entry). A sterile site means any sites deep to the skin and skin structures, including deep visceral and musculoskeletal abscesses that have been obtained in a sterile manner.
- Diagnosis of new foci between 14 and 90 days after platform entry. The presence of new foci will be determined by the site investigator and can incorporate clinical, radiological, microbiological and pathological findings.
- C. difficile diarrhoea as determined by a clinical laboratory in the 90 days following platform entry for participants ≥2 years of age. This means a stool submitted to a clinical laboratory has tested positive for C. difficile toxin or toxin gene.
- Serious adverse reactions (SARs) in the 90 days following platform entry.
- Health economic costs as detailed in the health economics appendix
- Proportion of participants who have returned to their usual level of function at day 90 as determined by whether the modified functional bloodstream infection score (FBIS) remained the same or improved between baseline and 90 days after platform entry Baseline=best within the 4 weeks prior to platform entry
- Desirability of outcome ranking 1 (modified Antibiotic Resistance Leadership Group version) at 90 days after platform entry
- Desirability of outcome ranking 2 (SNAP version) at 90 days after platform entry
- Total number of antibiotic days (IV and/or oral/enteral) in the 90 days following platform entry.
- Days alive and free of antibiotics in the 90 days following platform entry.
