About this study
Official title: Evaluation of the Efficacy and Safety of Meloxicam Injection for Postoperative Analgesia in Abdominal Surgery Patients: A Randomized, Double-Blind, Placebo-Controlled, Multicenter, Phase 3 Clinical Trial
This study aims to evaluate the analgesic efficacy and safety of meloxicam injection in subjects with moderate-to-severe pain following abdominal surgery. The primary efficacy endpoint is the summed pain intensity difference over 24 hours ( SPID24)
- Being tested
- Meloxicam Injection, Sodium Chloride Injection
What participants receive

Intravenous meloxicam Injection, 30mg every 24 hours, for a total of 2 doses
Sodium Chloride InjectionDrug
Intravenous Sodium Chloride Injection, 18mg every 24 hours, for a total of 2 doses

| Placebo | Placebo comparator | Not described Receives: Drug: Sodium Chloride Injection |
What is being measured
The primary outcome is the main question the study is designed to answer.
Summed Pain Intensity Difference Over the First 24 Hours (SPID24)
Pain intensity was recorded using a Numeric Pain Rating Scale (Range 0-10) where 0 equates to no pain (better), and 10 equates to the worst pain imaginable (worse). Pain intensity scores were to be recorded at the following time points: 15 minutes, 30 minutes, 1 hour, 1.5 hours, 2 hours, 3 hours, 4 hours, 6 hours, 8 hours, 10 hours, 12 hours, 14 hours, 16 hours, 18 hours and 24 hours post Dose1. Pain intensity differences from baseline at each time point were calculated and a time weighted summed pain intensity difference (SPID) was then calculated. Time weighted SPID calculations were computed by multiplying a weight factor to each score prior to summation. The weight factor at each time point was the time elapsed since the previous observation. A smaller SPID value (i.e. more negative) was better.
Measured: 24 Hours
Secondary outcomes (7)
Proportion of Participants Utilizing Rescue Analgesia
Rescue analgesia (Morphine Hydrochloride Injection 2mg) was available to Participants with inadequately controlled pain upon request.
Measured: 48 Hours
Number of Doses of Rescue Analgesia Utilized Subject
Rescue analgesia (Morphine Hydrochloride Injection 2mg) was available to Participants with inadequately controlled pain upon request.
Measured: 48 Hours
Number of Times of Rescue Analgesia Utilized Subject
Rescue analgesia (Morphine Hydrochloride Injection 2mg) was available to Participants with inadequately controlled pain upon request.
Measured: 48 Hours
Summed Pain Intensity Difference (SPID) at Other Intervals
Pain intensity was recorded using a Numeric Pain Rating Scale (Range 0-10) where 0 equates to no pain (better), and 10 equates to the worst pain imaginable (worse). Pain intensity scores were to be recorded at the following time points: 15 minutes, 30 minutes, 1 hour, 1.5 hours, 2 hours, 3 hours, 4 hours, 6 hours, 8 hours, 10 hours, 12 hours, 14 hours, 16 hours, 18 hours hours post Dose1. Thereafter pain assessments were to be recorded every 6 hours until 48 hours post Dose 1. Pain intensity differences from baseline at each time point were calculated and a time weighted summed pain intensity difference (SPID) was then calculated. Time weighted SPID calculations were computed by multiplying a weight factor to each score prior to summation. The weight factor at each time point was the time elapsed since the previous observation. A smaller SPID value (i.e. more negative) was better.
Measured: 48 Hours
TOTPAR (Total Pain Relief)
Pain relief will be evaluated considering the Sum of Total Pain Relief (TOTPAR) over 0-12 hours,0-18 hours,0-24 hours,0-48 hours post-dose. Pain relief will be evaluate using a Categorical Pain Relief Rating Scale (0 = No relief, 1 = Mild relief, 2 = Moderate relief, 3 = Marked relief, 4 = complete relief)
Measured: 48 Hours
Time to First Dose of Rescue Analgesia
Rescue analgesia (Morphine Hydrochloride Injection 2mg) was available to Participants with inadequately controlled pain upon request.
Measured: 48 Hours
Investigator and subject satisfaction scores for analgesic treatment
Satisfaction scores will be evaluate using a 5 point scale (0-4) with categories of 0-poor, 1-fair, 2-good, 3-very good, or 4-excellent.
Measured: 48 Hours

Primary outcome
Summed Pain Intensity Difference Over the First 24 Hours (SPID24)
Time frame: 24 Hours
Pain intensity was recorded using a Numeric Pain Rating Scale (Range 0-10) where 0 equates to no pain (better), and 10 equates to the worst pain imaginable (worse). Pain intensity scores were to be recorded at the following time points: 15 minutes, 30 minutes, 1 hour, 1.5 hours, 2 hours, 3 hours, 4 hours, 6 hours, 8 hours, 10 hours, 12 hours, 14 hours, 16 hours, 18 hours and 24 hours post Dose1. Pain intensity differences from baseline at each time point were calculated and a time weighted summed pain intensity difference (SPID) was then calculated. Time weighted SPID calculations were computed by multiplying a weight factor to each score prior to summation. The weight factor at each time point was the time elapsed since the previous observation. A smaller SPID value (i.e. more negative) was better.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 18 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Summed Pain Intensity Difference Over the First 24 Hours (SPID24) (time frame: 24 Hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2025.
