What is being measured
The primary outcome is the main question the study is designed to answer.
the Sum of Pain Intensity Differences in Pain Score Over 48 Hours in the rest state
Pain intensity will be evaluated using an 11-point (0-10) Numeric Pain Rating Scale (NPRS), with higher numbers indicating a higher pain intensity, administered over 48 hours. Time weighted average change from baseline is calculated using the following: time weighted sum of pain intensity differences (SPID) divided by a constant (48 hours) to yield values on the 0-10 NPRS.
Measured: 48-hours

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing SHR8554, Saline Solution and Morphine in people with Pain, run by Jiangsu HengRui Medicine Co., Ltd. at 1 site in China.
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 3 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 12 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Yong Cao, M.M (+0518-81220121, caoyong@hrs.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the Sum of Pain Intensity Differences in Pain Score Over 48 Hours in the rest state (time frame: 48-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 12 Aug 2021.
