EsketaminePhase 2/3NCT06117917
Esketamine Combined With Pregabalin on CPSP in Spinal Patients.
A Phase 2/3 study testing S-ketamine and pregabalin in people with Esketamine and Pregabaline, run by Beijing Tiantan Hospital at 1 site in China.
Trial summary
Chronic postsurgical pain has become one of the most common complications of surgery. The quality of life will be impacted once the postsurgical patients are combined with persistent pain. What's more, the postsurgical pain may increase other adverse outcomes. Read more about this study

About this study
Official title: Esketamine Combined With Pregabalin on Chronic Postsurgical Pain in Patients Undergoing Primary Spinal Tumor Surgery.
Chronic postsurgical pain has become one of the most common complications of surgery. The quality of life will be impacted once the postsurgical patients are combined with persistent pain. What's more, the postsurgical pain may increase other adverse outcomes. It's important to find a better way to keep the postsurgical patients away from postoperative pain. Esketamine and pregabalin have become potentially effective drugs on CPSP.
- Conditions
- Esketamine, Pregabaline, Chronic Post Operative Pain
- Being tested
- S-ketamine and pregabalin, Normal saline and placebo capsule

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing S-ketamine and pregabalin in people with Esketamine and Pregabaline, run by Beijing Tiantan Hospital 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 4 inclusion and 10 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 7 Nov 2023. 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 Ruquan Han, M.D., Ph D (8610-59976660, ruquan.han@ccmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the proportion of patients with chronic postsurgical pain during 3 months after operation (time frame: 3 months postoperatively). 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 7 Nov 2023; AzTrials last refreshed its copy on 7 Nov 2026.
