Tislelizumab Plus Concurrent Chemoradiation in Older With ESCC (TCRTOE)

Tislelizumab Combined With Concurrent Chemoradiation Versus Concurrent Chemoradiation for Older Patients With Inoperable Locally Advanced Esophageal Squamous Cell Carcinoma: a Randomized, Parallel-controlled, Multicenter Phase II Clinical Study

This study was conducted in elderly (≥70 years old) patients with locally advanced esophageal squamous cell carcinoma. Aim to find the difference in efficacy and safety between tirilizumab combined with concurrent chemoradiation and standard concurrent chemoradiation.

Concurrent chemoradiation is the standard treatment for elderly esophageal cancer. Tirelizumab is the first-line and second-line standard treatment for advanced esophageal squamous carcinoma. However, the effect of tirilizumab combined with concurrent chemoradiation for elder with locally advanced esophageal squamous cell carcinoma is unkown.

In the study, the investigators plan to enroll 136 elderly subjects with locally advanced esophageal cancer from five hospitals in China. The enrolled patients will be randomly divided into two groups: tirilizumab combined with concurrent chemoradiation group (Tislelizumab + radiotherapy + tigio) and concurrent chemoradiation group (radiotherapy + tigio). The treatment efficiency and safety will be evaluated.

6. Presence of measurable and/or non-measurable lesions as defined by RECIST 1.1;
7. Haven't received any previous systemic anti-tumor therapy (including but not limited to systemic chemotherapy, radiotherapy, molecularly targeted drug therapy, immunotherapy, biologic therapy, topical therapy and other investigational therapeutic agents);
8. Provide fresh or archived tumour tissue samples within 6 months (fresh samples preferred) for biomarker analysis (e.g.PD-L1). Sample types are formalin-fixed, paraffin-embedded [FFPE] tumour tissue blocks or at least 5 unstained, 3-5 μm thick FFPE tumour tissue sections;
9. Expected survival ≥ 3 months;

11. Adequate renal function, defined as creatinine ≤1.5× ULN or measured or calculated creatinine clearance ≥60 mL/min for those with creatinine levels >1.5× ULN (Calculated from the Cockcroft-Gault formula);
12. Adequate hepatic function, defined as total bilirubin ≤1.5× ULN and ALT/AST/AKP levels ≤2.5× ULN and albumin ≥2.8 g/dl;
13. Adequate coagulation function, defined as INR ≤1.5× ULN and APTT≤1.5× ULN unless the patient is receiving anticoagulant therapy as long as INR is within the therapeutic range;
14. Documented informed consent.

Exclusion Criteria:

1. Surgery for esophageal cancer;
2. Esophageal fistulae due to infiltration of the primary tumour;
3. Risk of gastrointestinal bleeding, oesophageal fistula or oesophageal perforation
4. Poor nutritional status, weight loss of ≥10% in the previous 2 months, with no significant improvement after nutritional intervention;
5. Major surgery or severe trauma within 4 weeks prior to first use of study drug;
6. Uncontrollable pleural effusion, pericardial effusion, or ascites that requires repeated drainage;

7. Received or receiving any of the following treatments in the past:

   3. Systemic treatment with corticosteroids (>10 mg prednisone equivalent dose per day) or other immunosuppressive agents is required for 2 weeks before the first dose of study treatment(except for the use of corticosteroids for local inflammation of the oesophagus and for the prevention of allergy and nausea and vomiting). Other special circumstances need to be communicated to the sponsor.Inhaled or topical steroids and adrenocorticotropic hormone replacement at doses >10mg/day prednisone efficacy dose are permitted if the patient does not have active autoimmune disease;
