Abstract

Purpose of review

Skin and soft tissue infections (SSTIs) are among the most frequent infections, contributing to significant morbidity and healthcare costs. Although numerous antibiotics are available for this indication, several medical needs remain unmet, especially for treating methicillin-resistant Staphylococcus aureus (MRSA) or mixed infections. This review summarizes the results achieved in the development of omadacycline, a new aminomethylcycline, which could have useful properties for the treatment of SSTIs.

Recent findings

The antimicrobial activity of omadacycline against the micro-organisms most frequently cultured in SSTIs has been confirmed in worldwide panels of clinical isolates, including MRSA, Gram-negative aerobes and some anaerobes. Pharmacokinetic data demonstrate interesting characteristics, allowing intravenous and oral administration. The Phase 3 OASIS-1 trial assessed the clinical efficacy and safety of omadacycline versus linezolid in SSTIs and demonstrated noninferiority and a good safety profile especially with regard to gastrointestinal effects. Analyses of subgroups of patients from this trial showed similar activity to that of the comparator drug, good safety and no dosage adjustments for age, sex or hepatic or renal impairment.

Summary

Because of its microbiological activities and pharmacokinetic profile, omadacycline may be particularly suitable for the treatment of SSTIs, whether managed in hospital or on an outpatient basis.
