简要总结
The purpose of this study is to evaluate the pharmacokinetic (PK) profile, safety, and efficacy of tislelizumab administered once every 2 weeks (Q2W) or once every 4 weeks (Q4W) in combination with chemotherapy as first-line treatment in Japanese participants with previously untreated, unresectable locally advanced, or metastatic esophageal squamous cell carcinoma (ESCC).
详细描述
Esophageal squamous cell carcinoma (ESCC) is a type of cancer that starts in the flat cells lining the inside of the esophagus (food pipe), the tube that carries food from the mouth to the stomach. In advanced stages, the cancer spreads to nearby tissues or other parts of the body.
Tislelizumab is used to block the programmed cell death protein-1 pathway so that immune system cells (T-cells) can better protect the body from infection and find tumor cells to attack. Tislelizumab may be used in combination with other therapies as a promising approach with potential therapeutic benefits to treat participants with cancer.
The purpose of this study is to test whether tislelizumab is safe and can help treat esophageal squamous cell carcinoma. The main goal of the study is to ensure that the treatments are safe by monitoring side effects and to understand how well participants respond to the treatment and whether their cancers shrink or disappear.
This study consists of two treatment groups. The first 10 participants will be randomly assigned (by chance, like flipping a coin) to one of two treatment groups; after that all participants will be assigned to Group 2.The study is open label, which means that the participants and the study doctors will know what treatment they receive.
Group 1: Tislelizumab every 2 weeks plus FOLFOX chemotherapy (oxaliplatin, leucovorin, and 5-FU) given by intravenous (IV) infusion every 2 weeks

入选标准
- •Able to provide written informed consent by the participant or by the participants' legally acceptable representative and can understand and agree to comply with the requirements of the study
- •Histologically confirmed, unresectable locally advanced, recurrent or metastatic ESCC not amenable to curative approaches such as definitive chemoradiation or surgery.
- •No previous systemic therapy for unresectable locally advanced, recurrent or metastatic ESCC
- •At least 1 measurable lesion per RECIST v1.1 as determined by investigator

Further contraception requirements after completing chemotherapy should follow the approved product labeling for each specific cytotoxic agent
排除标准

- •Uncontrollable pleural effusion, pericardial effusion, or ascites requiring frequent drainage (clinically significant recurrence requiring an additional intervention within 2 weeks of intervention) and/or diuretics within 7 days prior to the first dose of study drugs (the cytological confirmation of any effusion is permitted)
- •Have an estimated life expectancy < 3 months, per the judgment of the investigator
- •Participants with active leptomeningeal disease or uncontrolled, untreated brain metastasis
- •Prior therapy with anti-programmed death protein-1 (anti-PD-1), anti-programmed death protein ligand-1(anti-PD-L1), anti-programmed death protein ligand- 2 (anti-PD-L2), or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways
- •Note: Other protocol defined Inclusion/Exclusion criteria may apply.
