Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain Intensity Scores	Mean area under the curve (AUC) of the Numeric Rating Scale (NRS) weighted sum of pain intensity scores (at rest) from 0-10 where 0 is no pain and 10 is the worst pain imaginable for CA-008 compared to placebo. AUC is calculated using the standard trapezoidal rule from serial measures of NRS taken every 4 hours from 0-96 hours following surgery and twice daily from 96h to Day 15	0 to Day 15 post dose
Secondary	Total Opioid Consumption	CA-008 versus placebo comparison, total opioid consumption in oral morphine equivalents	0 to Day 15 post dose
