Clinical Trial Summary

This was a Phase 4, multicenter, open-label safety study of a single 1200 milligrams (mg) IV infusion of oritavancin in adult participants on chronic warfarin with acute bacterial skin and skin structure infection (ABSSSI) suspected or proven to be caused by Gram-positive pathogens. An additional group of participants with ABSSSI, who were not on concomitant warfarin therapy, were also enrolled to obtain additional information following a single dose of oritavancin administration.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)	An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment, including abnormal vital signs or laboratory assessments. An SAE was defined as any untoward medical occurrence that at any dose resulted in any of the following outcomes as fatal, life-threatening, required in-participant hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect, an important medical event. A summary of all SAEs and Other AEs (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.	Up to 2 weeks after first administration of oritavancin
Secondary	Number of Participants With a Clinical Response of Cure	Participants were classified by investigator assessment as "success" for clinical response of cure if all of the following were met: cessation of spread or reduction of the lesion; resolution (absence) of fever (temperature less than 37.7° Celsius); no rescue antibiotic medication; complete or nearly complete resolution of baseline signs and symptoms of the primary infection such that no further treatment with antibiotics was needed.	At 48 to 72 hours after start of oritavancin dose and at Day 7
