We know that, AFN-1252, is a selective inhibitor of Staphylococcus aureus enoyl-acyl carrier protein reductase (FabI), which is involved in fatty acid biosynthesis.
Now, Affinium Pharmaceuticals announced today that its Phase 2a clinical trial evaluating oral AFN-1252 in acute bacterial skin & skin structure infections (ABSSSI) demonstrated excellent efficacy and safety data, marking a significant proof-of-concept milestone for Affinium's first-in-class, novel antibiotic targeted against bacterial fatty acid biosynthesis inhibition (FabI inhibitors).
A clinical study in 103 patients from 18 centers in the USA and Canada confirms excellent efficacy, safety and tolerability of 200 mg of oral AFN-1252 dosed twice daily for 5-14 days in patients with acute bacterial skin and skin structure infections (ABSSSI) due to Staphylococcus". Patients were recruited from outpatient or emergency room settings. The enrolled patients had a variety of skin infections of ≥ 75 cm2 in size, including severe abscesses (38%), cellulitis (27%), and wound infections (35%). Investigators had the option of adding a second antibiotic to cover other potential pathogens or admitting the patient into the hospital. The vast majority of the patients were treated with oral AFN-1252 as monotherapy in the outpatient setting based on the suspicion of staphylococci from the clinical presentation and pretreatment Gram stain. This study fully utilized recent FDA guidances for clinical trials in ABSSSI, including both entry and efficacy criteria.
