Description: Omadacycline HCl (PTK-0796; trade name: Nuzyra), the hydrochloride salt of omadacycline, is an aminomethyl tetracycline antibiotic approved in 2018 to treat community-acquired bacterial infections such as acute bacterial skin and skin structure infections (ABSSSI), community-acquired bacterial pneumonia (CABP), and urinary tract infections (UTI).

Protocol	In Vitro	In vitro activity: Omadacycline is a novel, aminomethyl tetracycline antibiotic being developed for oral and intravenous (IV) administration to treat community-acquired bacterial infections such as acute bacterial skin and skin structure infections (ABSSSI), community-acquired bacterial pneumonia (CABP), and urinary tract infections (UTI). In vitro, omadacycline has activity against Gram-positive and Gram-negative aerobes, anaerobes, and atypical pathogens including Legionella and Chlamydia spp. Omadacycline offers once daily oral and IV dosing and a clinical tolerability and safety profile that compares favorably with contemporary antibiotics used across serious community-acquired infections where resistance has rendered many less effective. In studies in patients with complicated skin and skin structure infections, including those with MRSA infections, omadacycline exhibited an efficacy and tolerability profile that was comparable to linezolid. Ongoing and planned clinical studies are evaluating omadacycline as monotherapy for treating serious community-acquired bacterial infections including Acute Bacterial Skin and Skin Structure Infections (ABSSSI) and Community-Acquired Bacterial Pneumonia (CABP). This review provides an overview of the discovery, microbiology, nonclinical data, and available clinical safety and efficacy data for omadacycline, with reference to other contemporary tetracycline-derived antibiotics. Cell Assay: The omadacycline MIC90s for MRSA, VRE, and beta-hemolytic streptococci are 1.0 μg/mL, 0.25 μg/mL, and 0.5 μg/mL, respectively, and the omadacycline MIC90s for PRSP and H. influenzae are 0.25 μg/ml and 2.0 μg/mL, respectively. Omadacycline is active against organisms demonstrating the two major mechanisms of resistance, ribosomal protection and active tetracycline efflux[1]. Omadacycline inhibits protein synthesis while having no significant effect on RNA, DNA and peptidoglycan synthesis. Further, omadacycline binds to the tetracycline binding site on the 30S subunit of the bacterial ribosome with enhanced binding similar to tigecycline based on additional molecular interactions.
	In Vivo	In vivo efficacy of omadacycline is demonstrated using an intraperitoneal infection model in mice. A single intravenous dose of omadacycline exhibits efficacy against Streptococcus pneumoniae, Escherichia coli, and Staphylococcus aureus, including tet (M) and tet (K) efflux-containing strains and MRSA strains. The 50% effective doses (ED50s) for Streptococcus pneumoniae obtained ranged from 0.45 mg/kg to 3.39 mg/kg, the ED50s for Staphylococcus aureus obtained ranges from 0.30 mg/kg to 1.74 mg/kg, and the ED50 for Escherichia coli is 2.02 mg/kg.
