Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • A diagnosis of complicated bacteremia or infective endocarditis
  • Gram-positive bacteremia at screening with methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant Staphylococcus aureus (MRSA) or Streptococci
  • Treatment with standard of care antibiotics for 72 hours (h) - 10 days
  • Defervescence for at least 24h and clearance of bacteremia from screening pathogen.

Exclusion criteria

Exclusion Criteria:

  • Embolic events
  • History of prosthetic valve surgery, cardiac device or prosthetic joint
  • Left-sided endocarditis due to Staphylococcus aureus (S. aureus)
  • Large mobile vegetations (>10 mm) on mitral valves
  • Perivalvular abscess
  • Uncomplicated bacteremia due to S. aureus
  • Gram-negative bacteria or fungi in blood cultures
  • Heart failure associated with infective endocarditis [ (LVEF) \<40%]
  • Intravascular material or removable infection source not intended to be removed within 4 days postrandomization
  • Planned valve replacement surgery within 3 days of randomization
  • shock, significant hepatic insufficiency or severe leukopenia [ (ANC) \< 500 cells/mm\^3]
  • Known osteomyelitis
  • to dalbavancin or other drugs in glycopeptide class
  • Infection with enterococci, coagulase-negative staphylococci, or with organism not susceptible to dalbavancin or vancomycin
  • /immune deficiency
  • Concomitant systemic antibacterial therapy for gram-positive infection other than that allowed in protocol
  • Pregnant or nursing females.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

What researchers measure

Primary outcomes

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 25, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
