Study of Daptomycin Safety and Efficacy for Complicated Skin and Skin Structure Infections (cSSSI) and Bacteremia in Renal Impairment (RENSE)
A Prospective, Multicenter, Randomized, Evaluator-blinded, Comparator-controlled Study to Describe the Safety and Efficacy of Daptomycin for the Treatment of Complicated Skin and Skin Structure Infections (cSSSI) and Staphylococcus Aureus Bacteremia Among Subjects With Moderate or Severe Renal Impairment
This is a multicenter, randomized, evaluator-blinded, comparator-controlled study. Participants were to be randomized (1:1) to daptomycin or comparator, stratified by degree of renal impairment (creatinine clearance [CLcr] 30 - 50 milliliters per minute [mL/min] [moderate impairment] and <30 mL/min [severe impairment]) and by type of infection (bacteremia and complicated skin and skin structure infections [cSSSI]) to create 4 cohorts defined as follows:
- Cohort 1: Bacteremia and CLcr <30 mL/min
- Cohort 2: Bacteremia and CLcr 30 - 50 mL/min
- Cohort 3: cSSSI and CLcr <30 mL/min
- Cohort 4: cSSSI and CLcr 30 - 50 mL/min
Participants will be treated and evaluated for safety and microbiological and clinical efficacy in accordance with their type of infection and degree of renal impairment. Peak and trough samples will be collected to assess exposure to daptomycin for participants on Day 1 and following the 5th dose.

Experimental: Daptomycin, Bacteremia, Severe Renal Impairment
Cohort 1. Daptomycin was given intravenously 6 milligrams per kilogram (mg/kg) per administration.
For bacteremia participants with Creatinine Clearance (CLcr) below 30 milliliters per minute (mL/min) and currently receiving hemodialysis, daptomycin was administered immediately following each hemodialysis session (3 per week) for 14 to 42 days based on disease resolution or Investigator discretion.
For participants not receiving dialysis, daptomycin was administered every 48 hours for 14 to 42 days based on disease resolution or Investigator discretion.

Active Comparator: Vancomycin or SSP, Bacteremia, Severe Renal Impairment
Cohort 1. Participants randomized to the comparator therapy group received vancomycin or penicillinase-resistant penicillin (nafcillin, oxacillin, or cloxacillin).
Investigators were allowed to select an agent based on local availability and normal treatment practices.
Participants randomized to comparator subsequently found to have an infection caused by Methicillin-Susceptible Staphylococcus Aureus (MSSA) could have switched from vancomycin to penicillinase-resistant penicillin (nafcillin, oxacillin, or cloxacillin) at the Investigator's discretion.
All treatments were dosed per Investigator's discretion and were administered intravenously (IV) until end of antibiotic therapy for bacteremia or until hospital discharge, whichever occurred first.
Investigators treated participants according to their usual decision-making and discretion.

Time Frame |
---|---|---|
Overall Therapeutic Outcome at Test of Cure (TOC)/Safety Visit
Time Frame: Baseline through TOC/Safety Visit
|
Participants were assigned a Sponsor-assessed clinical outcome based on the following definitions at the TOC/Safety visit: Failure: Assessed as a failure at any time by the Investigator or received non-study antimicrobial therapy for lack of efficacy or had the primary site of infection removed completely by surgery or underwent surgery to treat the infection >4 days after starting study medication. Success: Were not assessed as a failure at any time and were assessed as a cure or improvement by the Investigator at the TOC visit. Non-evaluable: Received potentially effective antimicrobial therapy during the study period for reasons other than lack of efficacy or received <4 days of study medication or were not assessed by the Investigator. |
