What is being measured
The primary outcome is the main question the study is designed to answer.
pCR(Pathological Complete Response)
Definition of pathology complete response is "no cancer cell, including lympho nodes"
Measured: within 14 working days after operation
Secondary outcomes (5)
MPR(Major Pathological Remission rate)
The residual tumor after neoadjuvant treatment ≤ 10% residual tumor lesion in surgical specimen compared to baseline.
Measured: within 14 working days after operation
ORR(Objective Response Rate)
The Objective Response Rate (ORR) will be defined as the proportion of patients with a best overall response of Complete Response (CR) or Partial Response (PR) (RECIST V1.1)
Measured: 3-4 weeks after the last cycle of neoadjuvant treatment
Rate of R0 resection
Measure the rate of R0 resection with all margins microscopically clear.
Measured: within 14 working days after operation
EFS (Events Free Survival)
The time from the start of treatment until any of the following events occur: any disease progression that prevents surgery, postoperative disease progression or recurrence, or death due to any cause
Measured: The date from the beginning of randomization to the date of first record. 5 years EFS
Safety assessment
Safety and tolerability based on incidence of treatment-emergent adverse events as assessed by CTCAE
Measured: From the first dose of study drug up to 30 days after last dose of any component of treatment or surgery or the initiation of subsequent anticancer therapy, whichever occurred first. Up to approximately 9 months.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Serplulimab in people with Esophageal Squamous Cell Carcinoma (ESCC), run by Union Hospital, Tongji Medical College, Huazhong University of Science and Technology 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 13 inclusion and 20 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: opening soon, as of the sponsor's last update on 11 Feb 2026. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Sheng Dr.Zhang, MD. PhD. (0086-139714426, tonydppx@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
pCR(Pathological Complete Response) (time frame: within 14 working days after operation). 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 11 Feb 2026.
