Inclusion criteria
✓. ≥ 18 years and ≤ 75 years on the day of signing informed consent form (ICF).
✓. Fully informed of the study, with good compliance and willing to provide written ICF. The ICF must be signed before performing any protocol-related procedure (that is not a part of subject's routine medical care).
✓. Subjects with pathohistologically or cytologically confirmed unresectable locally advanced, relapsed or metastatic ESCC (based on American Joint Committee on Cancer \[AJCC\] Guideline version 8, see Appendix 14.2)
✓. Subjects must not be eligible for radical therapy such as radical chemoradiotherapy or surgery.
✓. Subjects who have not received any systemic anti-neoplastic therapy as the main regimen for locally advanced or metastatic ESCC. (Subjects who received prior neoadjuvant, adjuvant or radical chemoradiotherapy for ESCC but had relapse or progression of disease 6 months after the completion of these treatments are allowed.)
✓. ECOG PS 0 or 1.
✓. Life expectancy ≥ 3 months.
✓. Subjects have at least one measurable lesion as evaluated by the investigator according to RECIST v1.1, and the baseline imaging assessment must be performed within 28 days prior to the first dose of investigational product. Target lesions in the past radiation fields, if confirmed as radiological progression, are considered as measurable lesions.
Exclusion criteria
✕. Adenocarcinoma, mixture of adenocarcinoma and squamous cell carcinoma, or other pathological type of esophageal cancer.
What they're measuring
1
Progression-free survival (PFS) assessed by Blinded Independent Central Review (BICR) according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
Timeframe: Approximately 43 months from the time of randomization
2
Overall survival (OS)
Timeframe: Approximately 43 months from the time of randomization
✕. Subjects with active central nervous system (CNS) metastasis and/or carcinomatous meningitis (that is symptomatic, or requires treatment, or no radiological evidence confirming the stability of the lesion within 28 days prior to the first dose of investigational product).
✕. With another active primary malignancy in the past 5 years, except local curable cancers that have undergone curative therapy, e.g. basal cell carcinoma of skin, squamous cell carcinoma of skin, superficial bladder cancer, prostate cancer in situ, breast cancer in situ or cervical cancer in situ.
✕. Known history of positive human immunodeficiency virus (HIV) test result or acquired immunodeficiency syndrome (AIDS).
✕. Any severe or uncontrolled systemic disease, e.g., diabetes mellitus or hypertension, that may increase the risk associated with participation in the study or investigational product administration, or compromise subject's ability to receive investigational product, as per investigator's judgment.
✕. Subjects who have previously received any treatment of antibody or drug that targets at T-cell coregulatory pathways or immune checkpoint pathways, e.g., antibodies targeting at programmed death receptor-1 (PD-1), programmed death receptor-ligand 1 (PD-L1), cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), OX-40, CD137, T cell immunoglobulin mucin molecule 3 (TIM-3), lymphocyte activation gene 3 (LAG-3), etc. Subjects who have received cell-based immunotherapy (e.g., cytokine-induced killer cell \[CIK\], chimeric antigen receptor T cell \[CAR-T\] immunotherapy, etc.).
✕. All toxicities except for alopecia and fatigue that are caused by the prior anti-neoplastic treatment has recovered to Grade 1 (according to National Cancer Institute Common Toxicity Criteria for Adverse Events \[NCI CTCAE\] v5.0).
✕. Subjects with history of allogenic stem cell or solid organ transplantation.
