Further study details as provided by Duke University:

Primary Outcome Measures:
  • Compare cure rate between algorithm and standard of care therapy [ Time Frame: 28-42 days after last dose of antibiotics ]
    To compare the cure rate at Test of Cure evaluation, between the proposed treatment algorithm and the standard of care therapy.

  • Evaluate safety of algorithm-based therapy [ Time Frame: 28-42 days after last dose of antibiotic ]
    To evaluate the safety of algorithm-based therapy as an alternative to current standard of care.


Secondary Outcome Measures:
  • Antibiotic days by treatment group [ Time Frame: 28-42 days after last dose of antibiotic ]
    This will be analyzed by evaluating the difference in antibiotic days by treatment group and calculating 95% confidence intervals around the difference in antibiotic days among study patients randomized to algorithm-based treatment vs. among study patients randomized to standard treatment.

  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Provide signed and dated informed consent. The patient's legally authorized representative (LAR) can provide a signed informed consent for the patient if allowed by local Institutional Review Board/Ethics Committee (IRB/EC) policy.
  2. Is ≥ 18 yrs of age.
  3. If the subject has an intravenous catheter in place then the subject and his/her primary health care provider must agree to have the catheter removed within 5 days of the initial blood culture draw with the exception of those subjects who meet criteria for simple CoNS bacteremia as defined in Table 1. The catheter may be retained in those subjects with simple CoNS bacteremia.
  4. Has blood stream infection defined as at least one blood culture positive for S. aureus or CoNS. In most cases, vancomycin(or other study drug alternative) will have been started prior to randomization. Enrollment windows depend on speciation and clinical classification as follows:

    1. identification of CoNS and classification as simple per Table 1-must be randomized within 3 calendar days of the start of treatment effective for the baseline infecting pathogen
    2. identification of CoNS and classification as uncomplicated per Table 1 must be randomized within 4 calendar days of the start of treatment effective for the baseline infecting pathogen
    3. identification of S. aureus - must be randomized within 12 calendar days of the start of treatment effective for the baseline infecting pathogen
  5. This criterion has been removed
  6. Women of child bearing potential must have a negative urine and/or serum pregnancy test.
  7. All patients of reproductive potential must be abstinent or agree to use double-barrier contraception while receiving study (algorithm based or Standard of Care) therapy.

Exclusion Criteria:

  1. Has known or suspected new complicated staphylococcal infection at the time of enrollment.
  2. Weigh ≥ 200 kg.
  3. Has non-removable intravascular foreign material at the time a positive blood culture was drawn (e.g., intracardiac pacemaker or cardioverter/defibrillator wires, hemodialysis access grafts, cardiac prosthetic valve, valvular support ring). Exception: coronary stents, inferior vena cava (IVC) filters in place > 6 weeks, patients with pacemakers whose baseline infecting pathogen is a CoNS, vascular stents in place for > 6 weeks, non-hemodialysis grafts in place >90 days and hemodialysis grafts not used within past 12 months and not previously infected are eligible for randomization. Arthroplasties and other extravascular devices, e.g. synthetic hernia repair mesh, and non-arthroplasty orthopedic prostheses including pins or plates, are acceptable as long as there are no signs or symptoms of foreign material-related infection at the time of randomization.
  4. This criterion has been removed
  5. Has a moribund clinical condition such that there is a high likelihood of death or cardiac surgery during the next three days.
  6. Has shock or hypotension (supine systolic blood pressure < 80 mmHg) or oliguria (urine output < 20 mL/h) unresponsive to fluids or pressors within four hours.
  7. Has received an investigational antibacterial agent with anti-staphylococcal activity within 30 days prior to randomization.
  8. Has a documented history of significant allergy or intolerance to all protocol-approved antibiotics anticipated to be effective for their infection.
  9. Has an infecting pathogen with confirmed reduced susceptibility to vancomycin (Minimum Inhibitory Concentrations (MIC) > 2 µg/mL) if known. Note: If reduced susceptibility to vancomycin is discovered after enrollment, the patient will be treated with daptomycin (if pathogen is susceptible). Patient will remain in study as appropriate and be evaluated in the Intent to Treat (ITT) analysis, but will be excluded from Protocol Population (PP) analyses.
  10. For S. Aureus patients, is severely neutropenic (absolute neutrophil count < 0.100x103/mm3) or is anticipated to develop severe neutropenia (absolute neutrophil count < 0.100x103/ mm3) during the study treatment period due to prior or planned chemotherapy. CoNS patients with neutropenia are eligible to be enrolled.
  11. This criterion has been removed
  12. Has previously known Human Immunodeficiency Virus (HIV) infection with a nadir CD4+ count of <100 cells/mm3 within the past 12 months
  13. Is considered unlikely to comply with study procedures or to return for scheduled post-treatment evaluations.
  14. Is pregnant or trying to get pregnant, nursing, or lactating.
  15. Has known or suspected septic arthritis, osteomyelitis, pneumonia or other metastatic focus of infection. CoNS patients with pneumonia and not being treated or anticipated to start treatment with antibiotics effective for the baseline infecting pathogen can be included
  16. Has polymicrobial blood stream infection including at least one non-staphylococcal species, except AFTER consultation with the Clinical Medical Monitor at DCRI. Note that it is possible that a subject may not have a known polymicrobial bloodstream infection at the time of randomization, but additional pathogen(s) can subsequently be isolated from the initial blood culture. These patients will be eligible to remain in the trial. Please also note that patients with S. aureus plus CoNS will follow the treatment pathway for S. aureus.
  17. This criterion has been removed.
  18. Is hemodialysis dependent or has end stage renal disease (Creatinine Clearance (CrCl) < 30 cc/min).
  19. Developed Staphylococcus aureus blood stream infection within 72 hours of percutaneous coronary revascularization
  20. Received of any of the following antibiotics for 7 or more of the 10 calendar days immediately preceding the calendar day that the initial positive blood culture was drawn:

    1. If methicillin susceptibility of the isolate is unknown at the time of enrollment: vancomycin; daptomycin; telavancin; tigecycline; linezolid (in either oral or IV administration); quinupristin/dalfopristin; piperacillin/tazobactam; penicillin; nafcillin; oxacillin; cloxacillin; cefazolin, ceftriaxone, ceftaroline, dalbavancin, oritavancin, tedizolid, and levofloxacin or equivalent fluoroquinolone (in either oral or IV administration) Note: ciprofloxacin is not an exclusion criteria.
    2. If the staphylococcal isolate is known to be methicillin resistant: vancomycin; daptomycin; telavancin; tigecycline; linezolid (in either oral or IV administration), quinupristin/dalfopristin, dalbavancin, oritavancin, tedizolid, and ceftaroline.

    Note: patients who have developed bacteremia after at least 7 days of prophylaxis with oral antibiotics have by definition failed prophylaxis and the oral antibiotic can be deemed non-effective for the index bacteremia. Oral antibiotics that have failed as prophylaxis in this manner will not be considered exclusionary or count towards the number of antibiotic days but must be stopped upon randomization
