Study of Anti-PD-L1 in Combination With Chemo(Radio)Therapy for Resectable Esophageal Squamous Cell Carcinoma

Prior treatment

• Previous chemotherapy, radiotherapy, and/or treatment with checkpoint inhibitors.
• Pulmonary fibrosis and/or severely impaired lung function precluding major surgery.
• Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (\>10 mg/day prednisone or equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment.
• Serious underlying medical condition which would impair the ability of the patient to receive the planned treatment, including prior allergic reactions to drugs containing Cremophor, such as teniposide or cyclosporine.
• Has an active infection requiring systemic therapy which has not resolved 3 days (simple infection such as cystitis) to 7 days (severe infection such as pyelonephritis) prior to the first dose of trial treatment.
• Patients with prior allogeneic stem cell or solid organ transplantation.

Other illness

• Past or current history of malignancy other than entry diagnosis interfering with prognosis of esophageal cancer.
• metastatic oesophageal cancer.
• Clinically significant cardiovascular disease (including myocardial infarction, unstable angina, symptomatic congestive heart failure, serious uncontrolled cardiac arrhythmia) precluding major surgery.
• Has an active autoimmune disease that has required systemic treatment in past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs).
• Dementia or altered mental status that would prohibit the understanding and giving of informed consent
• Has a diagnosis of acute or chronic hepatitis B, hepatitis C, known immunodeficiency or human immunodeficiency virus (HIV).

Lab values

• Pregnancy (positive serum pregnancy test), planning to become pregnant, and lactation.

Other

• T1, T2 tumors or in situ carcinoma.
• Pre-existing motor or sensory neurotoxicity greater than WHO grade 1.

• Histologically proven squamous cell carcinoma of the esophagus.
• Surgical resectable (T3 or T4b, N0 or N+, M0), as determined by Endoscopic Ultra Sound (EUS),PET/CT, Esophageal MRI and enhanced CT scan of neck, thorax and abdomen.
• Tumor length longitudinal ≤ 10 cm; if larger than 10 cm, inclusion should be discussed with the principal investigator.
• 18≤Age≤75.
• Tumor does not involve gastro-esophageal junction.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Adequate hematological, renal and hepatic functions defined as:
  • neutrophiles ≥ 1.5 x 109/L platelets ≥ 100 x 109/L alanine transaminase≤2 x upper normal limit hemoglobin ≥ 5.6 mmol total bilirubin ≤ 1.5 x upper normal limit creatinine clearance (Cockroft) ≥60 ml/min
• Written, voluntary informed consent.
