New hope for esophageal cancer: triple therapy enters major trial
NCT ID NCT07251062
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new combination of drugs for people with advanced or metastatic esophageal squamous cell carcinoma who have not had prior treatment. The experimental therapy includes SYS6010 (a targeted antibody-drug conjugate) plus SG001 (an immunotherapy), with or without standard chemotherapy. The trial aims to see if this combo shrinks tumors and extends survival. About 737 participants will be enrolled across multiple centers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SYS6010 (an antibody-drug conjugate targeting EGFR) combined with SG001 (an anti-PD-1 immunotherapy), with or without chemotherapy (5-FU or capecitabine)
- What this could lead to
- If successful, this could offer a new first-line treatment option for advanced esophageal cancer, potentially improving tumor shrinkage and survival.
- What could go wrong
- This is an early-to-mid-stage trial (phase 2/3) with no results yet. Side effects from the drug combination may be significant, and the treatment may not work better than existing therapies.

Inclusion Criteria: 1. Be able to understand and voluntarily sign the written ICF; 2. Age 18-75 (inclusive) years, male or female; 3. With histologically/cytologically confirmed esophageal squamous cell carcinoma that is either locally advanced unresectable or metastatic, with no prior systemic antitumor therapy administered for the recurrent/metastatic disease setting. Have at least one measurable lesion that meets the RECIST v 1.1 criteria at baseline; 4. Eastern Cooperative Oncology Group (ECOG) performance status score: 0-1; 5. Life expectancy ≥ 3 months; Exclusion Criteria: 1. Prior treatment involving topoisomerase I inhibitors (including ADC drugs that contain topoisomerase I inhibitors as toxins); 2. Prior treatment with immune checkpoint inhibitors or other agents targeting T-cell co-stimulatory/co-inhibitory pathways (e.g., anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4, anti-CD137 antibodies) 3. With a history of ≥Grade 3 allergic reactions to monoclonal antibodies, or with known hypersensitivity or intolerance to SYS6010, SG001, paclitaxel, carboplatin, cisplatin, fluorouracil, or any of their excipients; 4. With dihydropyrimidine dehydrogenase (DPD) deficiency.
