Further study details as provided by Alkermes, Inc.:

Primary Outcome Measures:
  • To determine the analgesic efficacy, duration of effect and safety of single doses of IV N1539 as measured by the SPID (summary of pain intensity) and TOPAR (summary of the time-weighted pain relief scores) from 0-24 hours. [ Time Frame: at 60 minutes post dose and at 24 hours ]
    Additionally, to determine the efficacy seen within the first hour after study drug administration, as measured by the SPID 0-60 minutes post-dose.

Secondary Outcome Measures:
  • To assess the safety and tolerability of IV N1539 by laboratory data, vital signs, wound site evaluation and Adverse Events [ Time Frame: 5-7 days post initial dosing ]
