E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To evaluate and compare the overall survival (OS) following treatment with tislelizumab in combination with chemotherapy compared to placebo in combination with chemotherapy when given as first-line treatment in patients with unresectable, locally advanced recurrent or metastatic ESCC |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate and compare the efficacy of tislelizumab in combination with chemotherapy compared to placebo in combination with chemotherapy as a first-line treatment in unresectable, locally advanced recurrent or metastatic ESCC as measured by PFS, ORR and DOR assessed by the investigator per RECIST v1.1
-To evaluate and compare the efficacy of tislelizumab in combination with chemotherapy with the efficacy of placebo in combination with chemotherapy as a first-line treatment in unresectable, locally advanced recurrent or metastatic ESCC as measured by OS in PD-L1 visually estimated combined positive score (vCPS)≥10 % subgroup
- To evaluate and compare health-related quality of life (HRQoL) based on patient-reported outcomes (PROs) between tislelizumab in combination with chemotherapy and placebo in combination with chemotherapy
- To compare the safety between tislelizumab in combination with chemotherapy and placebo in combination with chemotherapy |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Pathologically (histologically) confirmed diagnosis of ESCC Note: Patients with adenocarcinoma differentiation < 5% of the viable tumor sample are eligible • Stage IV unresectable ESCC at first diagnosis OR unresectable, locally advanced recurrent or metastatic disease (per AJCC 7th Edition), if there is prior neoadjuvant/adjuvant therapy with platinum-based chemotherapy, a treatment-free interval of at least 6 months is required
|
|
E.4 | Principal exclusion criteria |
• Palliative radiation treatment for ESCC within 4 weeks of study treatment initiation • Prior systemic therapy for unresectable, locally advanced recurrent or metastatic ESCC Note: Patients with prior systemic concurrent chemotherapy in concurrent chemoradiotherapy are eligible • Received prior therapies targeting PD-1, PD-L1 or PD-L2 • Active leptomeningeal disease or uncontrolled brain metastasis. Patients with a history of treated and, at the time of screening, stable central nervous system (CNS) metastases are eligible, provided they meet all the following: i. Brain imaging at screening shows no evidence of interim progression, clinically stable for at least 2 weeks and have no evidence of new brain metastases ii. Have measurable and/or evaluable disease outside the CNS iii. No ongoing requirement for corticosteroids as therapy for CNS disease; off steroids 3 days prior to randomization; anticonvulsants at a stable dose are allowed iv. No stereotactic radiation or whole-brain radiation within 14 days prior to randomization • Patients with evidence of fistula (either esophageal/bronchial or esophageal/aorta) • Uncontrollable pleural effusion, pericardial effusion, or ascites requiring frequent drainage or medical intervention (clinically significant recurrence requiring an additional intervention within 2 weeks of intervention) • Evidence of complete esophageal obstruction not amenable to treatment • Unintentional weight loss ≥ 5% within one month prior to randomization or Nutritional Risk Index (NRI) < 83.5 per investigator's choice • Patients receiving chemotherapy doublet C (platinum and paclitaxel) must not have peripheral neuropathy ≥ Grade 2 at baseline |
