The incidence and patient outcomes of ABSSSI by iclaprim MIC values in the phase 3 REVIVE trials for treatment of acute bacterial skin and skin structure infections

The incidence and patient outcomes of Staphylococcus aureus isolates by iclaprim MIC was determined among patients from two phase 3 studies for the treatment of acute bacterial skin and skin structure infections (ABSSSI), REVIVE-1 and -2. Iclaprim MIC90 values were 0.12 µg ml for S. aureus (0.12 µg ml against methicillin-sensitive and 0.25 µg ml against methicillin-resistant S. aureus). The incidence of culture confirmed S. aureus isolates among patients with ABSSSI with an iclaprim MIC > 8 µg ml was 2.0 % (16/790). The clinical outcomes varied by MICs for early clinical response (63-100 %), end of therapy response (81-100 %) and the test of cure response (75-100 %). For microbiological outcomes of these infections, the end of therapy response was 80-100 % and the test of cure response was 88-100 %.
