Becotatug Vedotin Plus Tislelizumab and Low-Dose Lenvatinib for Advanced Esophageal Squamous Cell Carcinoma, Phase II
36 participantsStarted 2026-08-01
Plain-language summary
Immunotherapy combined with chemotherapy has become the first-line standard of care for advanced esophageal squamous cell carcinoma (ESCC), significantly improving patient survival. However, with the widespread adoption of first-line immunotherapy, most patients eventually develop immune resistance. After first-line treatment failure, there is currently no established standard effective therapy for second-line ESCC. Therefore, more effective and safer treatment options are urgently needed for second-line advanced ESCC.
This is a prospective, single-arm, single-center, open-label, Phase II clinical study aiming to evaluate the efficacy and safety of Becotatug Vedotin combined with Tislelizumab and low-dose Lenvatinib in patients with advanced ESCC who have failed first-line therapy. Eligible patients will receive Becotatug Vedotin combined with Tislelizumab and low-dose Lenvatinib. The primary endpoint is objective response rate (ORR) assessed per RECIST v1.1. Secondary endpoints include progression-free survival (PFS), disease control rate (DCR), duration of response (DOR), overall survival (OS), and safety.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
.Age ≥ 18 years, male or female. 2.Histopathologically or cytologically confirmed recurrent or metastatic esophageal squamous cell carcinoma.
.Failed first-line or above standard systemic therapy for advanced disease. 4.Patients must be able to provide tumor specimens (paraffin blocks, paraffin-embedded sections, or fresh tissue sections) from primary or metastatic lesions for pathological testing. The most recent archived tumor tissue specimen may be used. If archived tissue is unavailable, a new biopsy is required.
.ECOG PS 0-2. 6.Expected survival ≥ 3 months. 7.At least one measurable target lesion assessable by CT or MRI according to RECIST version 1.1 criteria.
.Adequate organ and bone marrow function, as demonstrated by the following laboratory values:
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Liver: Total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)≤2.5×ULN; for patients with liver metastases, ALT and AST≤5×ULN.
. Kidney: Creatinine clearance (Ccr) ≥ 50 mL/min (calculated using the Cockcroft-Gault formula).
. Coagulation: International normalized ratio (INR) ≤ 1.5 × ULN and activated partial thromboplastin time (APTT) ≤ 1.5 × ULN (except for patients receiving therapeutic anticoagulation).
Exclusion criteria
. Prior malignancy within 5 years, except for carcinoma in situ, basal cell carcinoma, or other malignancies considered cured with negligible risk of recurrence.
. Known hypersensitivity to any component of the study regimen.
. High risk of gastrointestinal bleeding, esophageal fistula, or esophageal perforation.
. Untreated or unstable parenchymal brain metastases, spinal cord metastasis or compression, leptomeningeal disease, or meningeal metastases.
. Evidence of active infection, including:1）Hepatitis B (HBsAg positive with HBV DNA ≥ 2000 IU/mL, excluding drug-induced or other causes of hepatitis);2）Hepatitis C (anti-HCV antibody positive with HCV RNA above the lower limit of detection);3）Human immunodeficiency virus (HIV) infection;4）Uncontrolled active bacterial, viral, fungal, rickettsial, or parasitic infections that have not resolved prior to study drug administration.
. Third-space fluid that cannot be controlled by drainage (e.g., massive ascites, pleural effusion, pericardial effusion), or subjects requiring drainage to control third-space fluid within 14 days prior to first dose.
. Any severe or uncontrolled systemic disease in the investigator's judgment.
