Drug: Daptomycin for Injection

  • Outcome Measures

    Primary Outcome Measures

    1. Percentage of Participants With an Adverse Event [Up to 56 days]

      An adverse event (AE) is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event.

    2. Percentage of Participants That Discontinued Study Treatment Due to an Adverse Event (AE) [Up to 42 days]

      An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event.

    Secondary Outcome Measures

    1. Percentage of Participants With Methicillin-Resistant Staphylococcus Aureus (MRSA) Infections Who Experienced Clinical Success [Up to 7 days following end of treatment (up to 49 days)]

      Clinical success in participants with MRSA infections was defined as either "Cure" - Resolution of clinically significant signs and symptoms associated with admission infection and no further antibiotic therapy required, OR "Improved"- partial resolution of clinical signs or symptoms of infection with no further antibiotic therapy required.

    2. Percentage of Participants With MRSA Infections Who Experienced a Microbiological Response [Up to 7 days following end of treatment (up to 49 days)]

      Participant-level microbiological response in participants with MRSA infections at baseline is defined as absence or presumed absence of all baseline infecting pathogens AND no gram-positive superinfection or gram-positive new infection, as assessed by infection site specimen culture or blood culture.

    3. Area Under the Concentration Time Curve From 0 to 24 Hours (AUC0-24hr) of Daptomycin [Pre-dose and at 15 minutes, 1 hour, 4 hours, and 12 hours post-dose on Day 3 of daptomycin treatment]

      Blood samples were collected at pre-specified time points to determine the AUC0-24 of daptomycin.

    4. Maximum Plasma Concentration (Cmax) of Daptomycin [Pre-dose and at 15 minutes, 1 hour, 4 hours, and 12 hours post-dose on Day 3 of daptomycin treatment]

      Blood samples were collected at pre-specified timepoints to determine Cmax of daptomycin.

    5. Time to Maximum Plasma Concentration (Tmax) of Daptomycin [Pre-dose and at 15 minutes, 1 hour, 4 hours, and 12 hours post-dose on Day 3 of daptomycin treatment]

      Blood samples were collected at pre-specified time points to determine Tmax of daptomycin

    6. Body Weight Adjusted Clearance (CLss/wt) of Daptomycin [Pre-dose and at 15 minutes, 1 hour, 4 hours, and 12 hours post-dose on Day 3 of daptomycin treatment]

      Blood samples were collected at pre-specified time points to determine CLss/wt of daptomycin at steady state.

    7. Volume of Distribution at Steady State (Vss) of Daptomycin [Pre-dose and at 15 minutes, 1 hour, 4 hours, and 12 hours post-dose on Day 3 of daptomycin treatment]

      Blood samples were collected at pre-specified time points to determine Vss (mL) of daptomycin.

    8. Apparent Terminal Half-Life (t½) of Daptomycin [Pre-dose and at 15 minutes, 1 hour, 4 hours, and 12 hours post-dose on Day 3 of daptomycin treatment]

      Blood samples were collected at pre-specified time points to determine the t½ of daptomycin.
