Inclusion criteria

* Men and women who are at least 18 years of age * Female subjects who are not pregnant or breastfeeding * Subjects undergoing a planned first laparoscopic colectomy * Subjects classified in American Society of Anesthesiologists (ASA) risk class of I or II * Subjects who report the pain intensity ≥ 5 on the NRS measured after surgery * Subjects who have the ability to understand study procedures and communicate clearly with the investigator and staff * Subjects who provide written informed consent prior to participation in the study Key

Exclusion criteria

* Subjects undergoing emergency or unplanned surgery * Subjects who had a previous laparoscopic colectomy procedure, or who had any laparoscopic resection procedure * Subjects with pre-existing conditions causing preoperative pain at the site of surgery * Female subjects who are pregnant or breastfeeding * Diagnosis of chronic pain (e.g., persistent pain with the intensity of NRS ≥ 5 at baseline)

MeasureTime frameDescription
Time-weighted Sum of Pain Intensity Differences for 12 Hours Post-dose (SPID 12)0-12 hours post-dosePain Intensity (PI) was assessed on an 11-point numerical rating scale from 0 (no pain) to 10 (worst pain imaginable). Time-weighted Sum of Pain Intensity Difference (PID) for 12 hours post-dose (SPID 12) was estimated using the linear trapezoidal rule (L x Hour) with the PI scores assigned from Time 0 to Time 12 hours post-dose using the following formula. The theoretical SPID 12 ranges from 0 to 120. A higher value of SPID indicates greater pain relief. SPID 12 = S \[T(i)-T(i-1)\] × \[PID(i)+PID(i-1)\]/2, when PID(i) =Predose PI-PI at Time i

Primary

Time-weighted Sum of Pain Intensity Differences for 12 Hours Post-dose (SPID 12)

Pain Intensity (PI) was assessed on an 11-point numerical rating scale from 0 (no pain) to 10 (worst pain imaginable). Time-weighted Sum of Pain Intensity Difference (PID) for 12 hours post-dose (SPID 12) was estimated using the linear trapezoidal rule (L x Hour) with the PI scores assigned from Time 0 to Time 12 hours post-dose using the following formula. The theoretical SPID 12 ranges from 0 to 120. A higher value of SPID indicates greater pain relief. SPID 12 = S \[T(i)-T(i-1)\] × \[PID(i)+PID(i-1)\]/2, when PID(i) =Predose PI-PI at Time i
