Participation in another study of an investigational drug or device within 30 days. 5. Receipt of a systemically or topically administered antibiotic within 14 days prior to randomization, except receipt of a single dose of a short-acting antibacterial drug 3 or more days prior to randomization. 6. Infection due to a dalbavancin or vancomycin-resistant organism. 7.

Recent bone marrow transplant, \> 20 mg prednisolone per day (or equivalent) or receiving immunosuppressant drugs after organ transplantation. 24. Regular, chronic antipyretic use in patients unable to modify during the first three days of study drug therapy. 25. Life expectancy less than 3 months. 26. Conditions that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results. 27. Prior participation in the study.
