Primary Outcome Measures:
  • Proportion of Participants With Clinical Success at the Day 7 (D7) and Day 14 (D14) Visit After Treatment Start [ Time Frame: at Day 7 and 14 ] [ Designated as safety issue: No ]
    Primary objective of the study was to evaluate the efficacy of intravenous (IV) daptomycin in the treatment of complicated skin and soft tissue infections (cSSTI) caused by methicillin-resistant Staphylococcus aureus (MRSA), as assessed by measuring the clinical success rate achieved at the day 7 and day 14 visit (D7, D14) after treatment start. Clinical success is defined as complete resolution of signs and symptoms of infection, or clinical improvement, i.e. partial resolution of signs and symptoms so that no further antibacterial treatment was required.


Secondary Outcome Measures:
  • Efficacy Assessed as Success After 4, 7, 10 and 14 Days of Treatment With Daptomycin on Infecting Gram Positive Bacteria [ Time Frame: At day 4, 7, 10 and 14 ] [ Designated as safety issue: No ]
    To evaluate the microbiological efficacy of intravenous (IV) daptomycin in the treatment of complicated skin and soft tissue infections (cSSTI) caused by methicillin-resistant Staphylococcus aureus (MRSA), as assessed by measuring the proportion of patients achieving eradication of the Gram-positive baseline organisms at the study visits on D4, D7, D10, and D14. Microbiological success is documented eradication of baseline Gram-positive organism or presumed eradication defined as clinical success and no culture performed because of absence of drainage or other material for culture.

  • Efficacy Assessed as Percentage of Patients With Clinical Success at Day 4 and 10 [ Time Frame: At day 4 and 10 ] [ Designated as safety issue: No ]
    To evaluate the efficacy of intravenous (IV) daptomycin in the treatment of complicated skin and soft tissue infections (cSSTI) caused by methicillin-resistant Staphylococcus aureus (MRSA), as assessed by measuring the clinical success rate achieved at the interim visits on day 4 (D4) and day 10 (D10) after treatment start. Clinical success is defined as complete resolution of signs and symptoms of infection, or clinical improvement, i.e. partial resolution of signs and symptoms so that no further antibacterial treatment was required.

  • Efficacy Assessed by Duration of Treatment With Daptomycin Intravenous [ Time Frame: At day 14 ] [ Designated as safety issue: No ]
  • Efficacy Assessed by Time of Resolution of Infection [ Time Frame: At day 14 ] [ Designated as safety issue: No ]
    Time to resolution of signs and symptoms of infection, time to resolution of fever (oral or tympanic temperature ≤37.5°C).

  • Safety Assessed by Hematological and Biochemical Tests, Urinalysis, and Recording and Follow-up of Emerging AE and SAE [ Time Frame: At day 14 ] [ Designated as safety issue: Yes ]
  • Evaluated Resource Utilization and Calculated Overall Treatment Cost (Including Treatment Period and Follow-up Period) [ Time Frame: at day 14 and follow up day i.e. day 30 ] [ Designated as safety issue: No ]

Enrollment: 52
Study Start Date: January 2007
Primary Completion Date: November 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Daptomycin
350 mg of Daptomycin was supplied as sterile lyophilized powder in glass vials. Each vial was to be reconstituted with 7 mL of normal saline or water for injection, to give a 50 mg/mL drug concentration. Daptomycin was to be administered as a 30-minute intravenous infusion, once daily for at least 7 days, at the dose of 4 mg/Kg, up to a maximum of 14 days.
Drug: Daptomycin

Criteria

Inclusion criteria:

  • Infection to be due to Gram-positive bacteria
  • Hospitalized subjects
  • Written informed consent
  • Female patients of childbearing potential must have a negative pregnancy test urine or serum at baseline and must use effective contraception throughout the study period.

Exclusion criteria:

  • Complicated skin and skin-structure infections of the following categories:
  • Infected burns

  • Infections associated with a permanent prosthetic device that will not be removed within 2 days of study enrollment
  • Uncomplicated skin or soft tissue infection
  • Documented bacteremia at baseline
  • Concomitant infection nearby the site of infection at baseline, potentially interfering with the evaluations
