Drug Information available for: Dalbavancin

Arm Intervention/treatment
Experimental: Dalbavancin, single dose Drug: Dalbavancin single dose
Dalbavancin, weight-adjusted dose, up to 1500mg. Intravenous (IV) administration. Aztreonam may be administered at randomization for presumed co-infection with a Gram-negative pathogen and could be discontinued if a Gram-negative pathogen is not documented by culture. For suspected anaerobic pathogens, metronidazole oral/IV may be used. Patients age birth to <3 months will only receive the single-dose regimen of dalbavancin; any concomitant antibacterial therapy may be administered in this age group based on local standard of care.

Experimental: Dalbavancin, two doses Drug: Dalbavancin two dose
Dalbavancin, weight-adjusted dose, up to 1000mg. Intravenous (IV) administration, with second dalbavancin weight-adjusted dose, up to 500mg. Aztreonam may be administered at randomization for presumed co-infection with a Gram-negative pathogen and could be discontinued if a Gram-negative pathogen is not documented by culture. For suspected anaerobic pathogens, metronidazole oral/IV may be used.

Active Comparator: Comparator Drug: Comparator
Course of either vancomycin not to exceed a total daily dose of 4000 mg;or oxacillin; or flucloxacillin not to exceed a total daily dose of 2000 mg. Intravenous (IV) administration. Possible oral switch after at least 72 hours from oxacillin or flucloxacillin to oral cefadroxil, or from IV vancomycin to oral clindamycin (for MRSA). Aztreonam may be administered at randomization for presumed co-infection with a Gram-negative pathogen and could be discontinued if a Gram-negative pathogen is not documented by culture. For suspected anaerobic pathogens, metronidazole oral/IV may be used. Additional comparator drugs may be used, if an alternate comparator regimen is indicated by local susceptibility patterns. No patient age birth to < 3 months will be randomized to the comparator arm.




Primary Outcome Measures :
  1. Number of patients with abnormal audiologic assessment [ Time Frame: Baseline to Day 28 (± 2 days)] ]
    Audiologic testing will be conducted in at least 7 children less than 2 years old (at least 3 of which are neonates) and will include evoked otoacoustic emissions testing, acoustic immittance measures (tympanometry and contra and ipsilateral acoustic reflex thresholds) and (optional) threshold auditory brainstem responses. Patients with an abnormal audiologic assessment at Day 28 (plus or minus 2 days) that exceeds, by a clinically significant margin, any abnormality observed in the Baseline assessment, will be considered to have an abnormal audiologic assessment

  2. Change in number of patients with the presence of either Clostridium difficile (CD), vancomycin-resistant enterococci (VRE), or both CD and VRE in bowel flora [ Time Frame: Baseline to Day 28 (± 2 days) ]
    Evaluated in patients from birth to < 2 years of age, by performing polymerase chain reaction (PCR) for Clostridium difficile (C diff) and culture for vancomycin-resistant enterococci (VRE) on a stool specimen or rectal swab.


Secondary Outcome Measures :
  1. Clinical response [ Time Frame: Baseline to 48 - 72 hours ]
    Defined as greater than 20% reduction in lesion size compared to baseline. In patients diagnosed with ABSSSI age birth to < 3 months, clinical response at 48-72 hours post-randomization is defined as cessation of increase in lesion size and decreased erythema or tenderness compared to baseline with no appearance of new lesions. In patients diagnosed with sepsis age birth to < 3 months, clinical response at 48-72 hours post-randomization is defined as improvement of at least one abnormal clinical and laboratory parameter related to sepsis.

  2. Clinical response evaluated at the end of treatment (EOT) visit: Cure [ Time Frame: Baseline and Day 14 (± 2 Days) ]
    Clinical response of Cure will be defined as resolution of the clinical signs and symptoms of infection, when compared to baseline. No additional antibacterial treatment is required for disease under study.

  3. Clinical response evaluated at the end of treatment (EOT) visit: Improvement [ Time Frame: Baseline and Day 14 (± 2 Days) ]
    Clinical response of Improvement will be defined as a reduction in severity of two or more, but not all, clinical signs and symptoms of infection, when compared with baseline (patients age 3 months to 17 years and ABSSSI patients age birth to <3 months). In sepsis patients age birth to < 3 months, improvement is defined as reduction in severity of at least one abnormal clinical and laboratory parameter related to sepsis, when compared with baseline. In patients age 3 months to 17 years, no additional antibacterial treatment is required for disease under study. In patients age birth to < 3 months, no rescue antibiotics required after at least 48 hours of start of study treatment. This outcome category will only be used at the EOT evaluation.

  4. Clinical response evaluated at the end of treatment (EOT) visit: Failure [ Time Frame: Baseline and Day 14 (± 2 Days) ]
    Clinical response of Failure will be defined as persistence or progression of baseline clinical signs and symptoms of infection after at least 2 days (48 hours) of treatment OR development of new clinical findings consistent with active infection.

  5. Clinical response evaluated at the end of treatment (EOT) visit: Unknown [ Time Frame: Baseline and Day 14 (± 2 Days) ]
    Clinical response of Unknown will be defined as extenuating circumstances precluding classification to Cure, Improvement or Failure

  6. Clinical response evaluated at the test of cure visit: Cure [ Time Frame: Baseline and Day 28 (± 2 Days) ]
    Clinical response of Cure will be defined as resolution of the clinical signs and symptoms of infection, when compared to baseline. No additional antibacterial treatment is required for disease under study.

  7. Clinical response evaluated at the test of cure visit: Failure [ Time Frame: Baseline and Day 28 (± 2 Days) ]
    Clinical response of Failure will be defined as persistence or progression of baseline clinical signs and symptoms of infection after at least 2 days (48 hours) of treatment OR development of new clinical findings consistent with active infection.

  8. Clinical response evaluated at the test of cure visit: Unknown [ Time Frame: Baseline and Day 28 (± 2 Days) ]
    Clinical response of Unknown will be defined as extenuating circumstances precluding classification to Cure or Failure

  9. Clinical response evaluated at follow-up visit: Cure [ Time Frame: Baseline and Day 54 (± 7 days) ]
    Clinical response of Cure will be defined as resolution of the clinical signs and symptoms of infection, when compared to baseline. No additional antibacterial treatment is required for disease under study.

  10. Clinical response evaluated at follow-up visit: Failure [ Time Frame: Baseline and Day 54 (± 7 days) ]
    Clinical response of Failure will be defined as persistence or progression of baseline clinical signs and symptoms of infection after at least 2 days (48 hours) of treatment OR development of new clinical findings consistent with active infection.

  11. Clinical response evaluated at follow-up visit: Unknown [ Time Frame: Baseline and Day 54 (± 7 days) ]
    Clinical response of Unknown will be defined as extenuating circumstances precluding classification to Cure or Failure

  12. Presence of baseline pathogen after treatment [ Time Frame: Baseline to Day 54 (± 7 days) ]
    Direct demonstration of eradication or persistence of the causative organism

  13. All-cause mortality: For patients age birth to < 3 months, all-cause mortality will be determined at test of cure (TOC) visit [ Time Frame: Baseline and Day 28 (± 2 days) ]
  14. Dalbavancin plasma concentration [ Time Frame: Within 14 (± 2) days of study drug administration ]
