About this study

This prospective, single-arm phase II study will evaluate the efficacy and safety of lymphatic-drainage-sparing short-course radiotherapy combined with camrelizumab and nab-paclitaxel/carboplatin as neoadjuvant treatment for patients with resectable, locally advanced thoracic esophageal squamous cell carcinoma. Participants will receive three 3-week cycles of camrelizumab plus chemotherapy, with 25 Gy in 5 fractions of short-course radiotherapy delivered to the primary tumor and radiographically positive lymph nodes while elective lymphatic drainage regions are spared. Definitive McKeown esophagectomy is planned 4-6 weeks after completion of neoadjuvant therapy. The primary endpoint is pathologic complete response (ypT0N0).

Read the detailed description

The study is designed as a Simon optimal two-stage, single-arm phase II trial. The target sample size is 33 participants, allowing for approximately 10% attrition. In stage 1, 15 participants will be enrolled; if at least 4 achieve pathologic complete response, enrollment will proceed to stage 2. A further 15 evaluable participants will then be enrolled. The protocol considers the regimen promising if at least 15 of 30 evaluable participants achieve pathologic complete response.

Eligible participants are treatment-naive adults aged 18-75 years with PET-CT and pathologically confirmed thoracic esophageal squamous cell carcinoma, clinical stage cT1b-3N1-2M0 or cT2-3N0M0 (AJCC 9th edition), ECOG performance status 0-1, measurable disease by RECIST v1.1, and disease considered amenable to R0 resection.

Neoadjuvant treatment consists of camrelizumab 200 mg intravenously on Day 1 every 3 weeks plus nab-paclitaxel 260 mg/m² on Day 1 and carboplatin AUC 5 on Day 1 for three cycles. Short-course radiotherapy (25 Gy in 5 fractions over 5 days) is delivered after the first cycle, targeting only the primary tumor and positive lymph nodes and sparing elective lymphatic drainage regions. Tumor imaging is performed after the second cycle and before surgery. McKeown esophagectomy is planned 4-6 weeks after completion of neoadjuvant therapy when hematologic and organ function have recovered. Postoperative survival follow-up is planned every 3 months for 3 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pathologic Complete Response (pCR) Rate

    Percentage of participants undergoing definitive surgery who have no residual viable tumor in the resected primary tumor and regional lymph nodes, defined in the protocol as ypT0N0.

    Measured: At definitive surgery, approximately 4-8 weeks after completion of neoadjuvant therapy.

Secondary outcomes (5)
  1. Major Pathologic Response (MPR) Rate

    Major pathologic response (MPR) is defined as ≤10% residual viable tumor cells in the primary esophageal tumor resection specimen, regardless of lymph node status, as pre-specified in study protocol. The percentage of participants achieving this protocol-defined MPR criterion in post-neoadjuvant surgical resection specimen will be calculated.

    Measured: At definitive surgery, approximately 4-8 weeks after completion of neoadjuvant therapy.

  2. Objective Response Rate (ORR)

    Percentage of participants with complete response or partial response according to RECIST v1.1 based on protocol-specified imaging assessments.

    Measured: From baseline to the preoperative tumor assessment, approximately 9-15 weeks after initiation of neoadjuvant therapy.

  3. R0 Resection Rate

    Percentage of participants undergoing esophagectomy with microscopically negative resection margins.

    Measured: Upon completion of final postoperative pathological assessment, expected within 7 days post-operatively

  4. Disease-Free Survival (DFS) Rate

    Disease-free survival rate at 1 and 3 years.

    Measured: 1 year and 3 years after surgery.

  5. Overall Survival (OS) Rate

    Overall survival rate at the specified time points. Survival will be estimated using the Kaplan-Meier method.

    Measured: 1 year and 3 years after surgery.

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 11 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: looking for participants now, as of the sponsor's last update on 9 Sep 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 Hongying Liao MD, Professor / Chief Physician, MD and PhD (+86-020-35919121, liaohy2@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathologic Complete Response (pCR) Rate (time frame: At definitive surgery, approximately 4-8 weeks after completion of neoadjuvant therapy.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07808853, which also lists 2 linked publications.

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 9 Sep 2026.
