The company also has in clinical development Radezolid, a next-generation IV/oral oxazolidinone designed to be a potent antibiotic permitting long-term treatment of resistant infections.
The pipeline also includes its preclinical RX-04 program, partnered with Sanofi, S.A., and other discovery stage anti-infective programs.
