    Outcomes

    Primary Outcome Measures

    Percentage of Participants With Clinical Improvement in the 3 General Categories of Pain, Inflammation, and Limb Function Based on the Investigator's Overall Assessment of Severity of Each of the Symptom Categories.
    Clinical improvement was based on the Investigator's overall assessment of severity of each of the 3 general symptom categories of Pain, Inflammation, and Limb Function. Based on this evaluation, a participant was considered to have met criteria for clinical improvement according to the following definition: If 3 general categories are present at baseline: at least a 1-point improvement (i.e. severe to moderate, moderate to mild, mild to absent) in at least 2 of the general categories and no worsening in the other. If 2 general categories are present at baseline: at least a 2-point improvement (i.e. severe to mild, moderate to absent) in at least 1 of the general categories and no worsening or new findings in the others OR at least a 1-point improvement in both and no new findings in the other. If 1 general category is present at baseline: at least a 2-point improvement (i.e., severe to mild, moderate to absent) in that category and no new findings in the others.

    Secondary Outcome Measures

    Percentage of Participants With Clinical Improvement Measured as a Composite End Point of Pain, Inflammation, Limb Function, Body Temperature, and C-reactive Protein at End-of IV (EOIV) Therapy Visit.
    A participant had a favorable outcome in this composite endpoint if all 3 of the following criteria were met: Clinical improvement in the general symptom categories of Pain, Inflammation, and Limb Function on or before Study Day 5; Body temperature ≤ 38°C (100.4°F) over the preceding 24 hours; and C-reactive Protein (CRP) decreased from baseline for participants who had a baseline CRP >ULN (upper limit of normal)) or remain <=ULN for participants who had a baseline <=ULN on or before Study Day 5. The EOIV visit is within 24 hours after the last dose of IV study drug and before switch to optional open label (PO) therapy, if applicable.
    Percentage of Participants With a Favorable Clinical Outcome
    Favorable clinical outcomes are clinical recovery and clinical cure. Clinical cure is defined as resolution of all acute symptoms of AHO or improvement to such an extent that no further intravenous antibacterial therapy is required. Clinical recovery is defined as clinical improvement in the composite end point three general categories of Pain, Inflammation, and Limb Function on or before Study Day 5, and no development of new symptoms of AHO; body temperature ≤ 38°C (100.4°F) for 24 hours; no new or additional bone or joint infection (e.g., abscess, spreading to other osseous or articular locations) such that no further antibacterial therapy or surgery are required; no hematogenous metastatic infection (e.g., abscess in liver, spleen, lung; other bones) or bacteremia.. The End of Therapy (EOT) visit is within 48 hours of last dose of PO therapy.
    Percentage of Participants With a Clinical Cure Categorized by Baseline Pathogen at Test of Cure
    At Test Of Cure (TOC) clinical cure is defined as resolution of all acute symptoms of AHO or improvement to such an extent that no further antibacterial therapy is required. Favorable microbiological outcomes are either eradication where the source specimen demonstrated absence of the original baseline pathogen; or presumed eradication where the source specimen was not available to culture, and the subject was assessed as a clinical cure. To have a favorable microbiological response, the outcome for each participant's baseline pathogen must be favorable (eradicated or presumed eradicated). Other pathogens include Arcanobacterium haemolyticum, Gram positive cocci, Staphylococcus epidermidis, Streptococcus dysgalactiae, Streptococcus mitis group and Streptococcus pyogenes.
    Percentage of Participants With Sustained Clinical Improvement
    Sustained clinical improvement was defined as participants with clinical improvement who further met the definition of clinical cure. Clinical improvement was in the three general categories of Pain, Inflammation, and Limb Function on or before Study Day 5. Clinical cure is defined as resolution of all acute symptoms of AHO or improvement to such an extent that no further intravenous antibacterial therapy is required. The EOT visit is within 48 hours of last dose of PO therapy.
    Percentage of Participants With a Favorable Microbiological Response Categorized by Baseline Pathogen at Test of Cure
    Favorable microbiological outcomes are either eradication where the source specimen demonstrated absence of the original baseline pathogen; or presumed eradication where the source specimen was not available to culture, and the subject was assessed as a clinical cure. For a favorable microbiological response, the outcome for each baseline pathogen must be eradicated or presumed eradicated. Other pathogens include Arcanobacterium haemolyticum, Gram positive cocci, Staphylococcus epidermidis, Streptococcus dysgalactiae, Streptococcus mitis group and Streptococcus pyogenes.

    5. Study Description

    Brief Summary
    The purpose of the study is to determine whether daptomycin is effective and safe in the treatment of pediatric participants with AHO when compared to vancomycin (or equivalent) or nafcillin (or β-lactam equivalent). The primary hypothesis is that daptomycin is non-inferior compared with vancomycin (or equivalent) or nafcillin (or β-lactam equivalent) with respect to improvement in Pain, Inflammation, and Limb Function on or before study Day 5.
    Detailed Description
    Acute hematogenous osteomyelitis is a common problem in the pediatric population, affecting approximately 5/10,000 children each year and accounting for approximately 1% of all pediatric hospitalizations. In children, osteomyelitis arises from bacteremic seeding of the bone metaphysis. Daptomycin, is a cyclic lipopeptide antibacterial active against most clinically significant gram-positive pathogens including drug-resistant strains such as Methicillin Resistant Staphylococcus (S.) aureus (MRSA) and Methicillin Susceptible S. aureus (MSSA). Daptomycin has proven clinical efficacy in adults in the treatment of complicated skin and skin structure infections (cSSSI) caused by aerobic gram-positive pathogens and the treatment of S. aureus bloodstream infections (bacteremia; SAB), including those complicated by right-sided infective endocarditis, caused by MSSA and MRSA. Although not indicated for osteomyelitis, daptomycin has been successfully used to treat osteoarticular infections in adults and children as salvage therapy and at medical centers with increasingly high rates of vancomycin resistant organisms. In addition, more comparative clinical trials are needed in pediatric AHO to better elucidate the optimal treatment regimen and clinical response.
