About this study
Official title: Clinical Trial of Total Neoadjuvant Therapy Combined With Adebrelimab in Locally Advanced Resectable Esophageal Squamous Cell Carcinoma
Esophageal cancer is a malignant tumor with high incidence rate and mortality in China. According to the data of the World Health Organization, 324000 new cases and 301000 deaths of esophageal cancer will occur in China in 2020, accounting for 53.70% and 55.35% of the global incidence and death of esophageal cancer respectively.
Surgery is the main method for locally advanced resectable esophageal cancer, combined with chemoradiotherapy(CRT), in order to achieve curative resection. However, after neoadjuvant chemoradiotherapy and surgery, 36-50% of patients still experience recurrence or metastasis, and the prognosis for early recurrence is worse. Adjuvant chemotherapy plays a particularly beneficial role in terms of disease-free survival(DFS) in patients who did not receive neoadjuvant therapy and patients with pathologic lymph-node-positive disease. however, less than 50% of eligible patients receive their scheduled adjuvant chemotherapy due to delays, treatment compliance, and postoperative complications. Among patients with resected esophageal cancer who had received neoadjuvant CRT, DFS was significantly longer among those who received nivolumab adjuvant therapy than among those who received placebo.

Total neoadjuvant therapy (TNT), attempts to deliver both systemic chemotherapy and neoadjuvant CRT prior to surgery, which may become a new treatment direction for patients with locally advanced resectable esophageal cancer. Ongoing progress in all treatment modalities involved in TNT holds the promise to enhance further the outcomes of patients with esophageal cancer. Immunotherapy, as a breakthrough therapy in the systemic treatment of advanced esophageal cancer, has become an indispensable component of the exploration of TNT model. Currently, several prospective exploratory studies suggest that immunotherapy combined with TNT can improve the pCR rate of esophageal cancer patients, achieving good short-term efficacy and tolerable safety.
However, further exploration is needed for the combination of immunotherapy and TNT. This study first explores the efficacy and safety of two types of total neoadjuvant therapy in phase II: the combination of adebrelimab and chemotherapy followed by chemoradiotherapy, or the combination of adebrelimab and chemotherapy after chemoradiotherapy. A more promising treatment plan will be selected for a phase III randomized controlled trial and confirm the superiority of adebrelimab combined with TNT over neoadjuvant CRT in terms of pathological complete response overall survival in patients with locally advanced resectable esophageal cancer.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Adebrelimab + paclitaxel/nab-paclitaxel + cisplatin followed by chemoradiotherapy, chemoradiotherapy followed by adebrelimab + paclitaxel/nab-paclitaxel + cisplatin and TNT treatment [TNT group one (phase 2) or TNT group two (phase 2)] in people with Esophageal Squamous Cell Carcinoma (ESCC), run by YIN LI 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 18 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 Mar 2025. 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 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?
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 Jianjun Qin, chief physician (86-13838008630, qinjianjun@cicams.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
pCR (phase 2 and phase 3) (time frame: one month after esophageal cancer surgery). The study lists 2 primary outcomes in all. 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 Mar 2025.
