Study of Daptomycin Safety and Efficacy for Complicated Skin and Skin Structure Infections (cSSSI) and Bacteremia in Renal Impairment
Prospective Multicenter Randomized Evaluator-blinded Comparator-controlled Study to Describe the Safety and Efficacy of Daptomycin for the Treatment of cSSSI and Staphylococcus Aureus Bacteremia Among Subjects With Renal Impairment

This is a multicenter, randomized, evaluator-blinded, comparator-controlled study. 1:1 randomization daptomycin or comparator, stratified by degree of renal impairment [creatinine clearance(CLcr) 30 - 50 mL/min and <30 mL/min] and by type of infection [bacteremia and complicated Skin and Skin Structure Infections (cSSSI)] to create 4 cohorts defined as follows:

  1. Bacteremia and CLcr <30 mL/min
  2. Bacteremia and CLcr 30 - 50 mL/min
  3. cSSSI and CLcr <30 mL/min
  4. cSSSI and CLcr 30 - 50 mL/min

Patients will be treated and evaluated for safety, 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 patients on Day 1 and following the 5th dose.
