Aspirin at a daily dose of less than or equal to 325 mg is allowed for cardiovascular prophylaxis if the subject has been on a stable dose regimen for greater than or equal to 30 days before screening and has not experienced any relevant medical problem.
14. Has a significant renal or hepatic disease, as indicated by clinical laboratory assessment (results of greater than or equal to 3 times the upper limit of normal [ULN] for any liver function test, including aspartate aminotransferase [AST], alanine aminotransferase [ALT], or creatinine greater than or equal to 1.5 times the ULN).
15. Has any clinically significant laboratory finding at screening that, in the opinion of the Investigator, contraindicates study participation.

Statistical methods / analysis
All subjects who receive at least one dose of the study drug will be included in the safety population. The safety population will be used for all summaries of study endpoints. Early withdrawals for any reason will be tabulated.

The demographic and clinical characteristics of the study population at study entry, including age, gender, race, ethnicity, indication (type of surgery, compound fracture), use of concomitant medications (e.g. opioids), vitals and laboratory results will be summarized as means, medians, standard deviations, ranges and frequencies and percentages as appropriate.

Treatment-emergent adverse events are defined as events first occurring or worsening during the course of the study, regardless of their relationship to the study drug. Treatment-emergent adverse events will be coded to MedDRA System Organ Class Code and Preferred Term and tabulated as frequencies and percentages in the following time periods: At any timepoint during the observational period; at any timepoint during the treatment period; on Day 1; Day 2; Day 3; Day 4; Day 5; Day 6+; and during follow-up. Clinically significant changes from baseline in vital sign measurements All subjects who receive at least one dose of the study drug will be included in the safety population. The safety population will be used for all summaries of study endpoints. Early withdrawals for any reason will be tabulated.

Clinically significant changes from baseline in vital sign measurements or laboratory test results will be classified as adverse events.

The proportion of TEAEs that are considered by the Investigator to be “probably” or “definitely” related to study medication (treatment-related AEs- TRAEs) will be summarized.

All cardiovascular, gastrointestinal, renal, hepatic, administration site conditions and bleeding-related AEs will be summarized and the proportion of these that are considered treatment-related will be tabulated.

The incidence of TEAEs will be summarized by gender, race, age (<65, 65-75, >75 years), duration of exposure (dosed for less than or equal to 48 hours, dosed for 48 hours – 4 days, dosed for greater than or equal to 5 days) and indication (surgery type, compound fracture). This analysis is subject to recruitment of sufficient participants within each subgroup.

Vital sign measurements and clinical laboratory values at each scheduled timepoint will be summarized with standard descriptive statistics, including means, standard deviations and ranges. Summary shift tables will be produced overall and by duration of treatment (dosed for less than or equal to 48 hours, dosed for 48 hours – 4 days, dosed for greater than or equal to 5 days) of the number of cases with normal baseline laboratory tests changed to abnormal at the end of the treatment period, and abnormal baseline laboratory tests worsened at the end of the treatment period, with the severity of changes summarized as proportional effects.

The use of concomitant medications following study drug administration will be summarized as frequencies and percentages within ATC-coded drug groups.

The frequency and percentage of subjects rating the study drug as ‘poor’, ‘fair’, ‘good’, ‘very good’ and ‘excellent’ will be summarized.
