S-1 and Oxaliplatin (SOX) Plus Sintilimab in the Locally Advanced Esophagogastric Junction Adenocarcinoma

Recruiting now · Phase 2

Conditions studied: Locally Advanced Gastroesophageal Junction Adenocarcinoma, Chemotherapy Effect

In brief

For locally advanced adenocarcinoma of esophagogastric junction(AEG) (cT3-4aN+M0), neoadjuvant chemotherapy was improved to downstage T and N stage, increase the resectability of tumor, and finally improve the long-term survival. Combination of perioperative PD-1 antibody and chemotherapy for locally advanced AEG could be a novel therapy to increase response rate and resectability and reduce recurrence rate. Sintilimab in this study is an anti-PD-1 monoclonal antibody for injection which has been approved for several malignant tumors. This study is a multi-center, open-label, randomized phase II clinical trial to evaluate tolerability, safety and efficacy of sintilimab in combination with perioperative chemotherapy in locally advanced AEG.

You may not qualify if…

• Suffer from other active malignant tumors within 5 years or at the same time. Cured localized tumors, such as skin basal cell carcinoma, skin squamous cell carcinoma, superficial bladder cancer, prostate carcinoma in situ, cervical carcinoma in situ, breast carcinoma in situ, etc. can be included in the group.
• Patients who are planning to undergo or have previously received organ or bone marrow transplantation.
• Myocardial infarction or poorly controlled arrhythmia (including QTc interval ≥ 450 ms for males and ≥ 470 ms for females) occurred within 6 months before the first medication (QTc interval is calculated by Fridericia's formula).
• There is NYHA standard grade III to IV cardiac insufficiency or color Doppler ultrasound examination: LVEF (left ventricular ejection fraction) <50%.
• Human immunodeficiency virus (HIV) infection.
• Suffer from active tuberculosis.
• Past and present patients who have interstitial pneumonia, pneumoconiosis, radiation pneumonia, drug-related pneumonia, severely impaired lung function, etc., which may interfere with the detection and management of suspected drug-related lung toxicity.
• There is a known active or suspicious autoimmune disease. Except those who were in a stable state of the disease at the time of enrollment (no need for systemic immunosuppressive therapy).
• Received treatment with live vaccine within 28 days before the first administration; except for the treatment of seasonal influenza with inactivated viral vaccine.
• Patients who need to receive systemic corticosteroids (> 10 mg/day curative dose of prednisone) or other immunosuppressive drugs within 14 days before the first medication or during the study period. However, the following conditions are allowed to enter the group: in the absence of active autoimmune diseases, patients are allowed to use topical or inhaled steroids, or adrenal hormone replacement therapy with a dose of ≤ 10 mg/day prednisone.
• Any active infection that requires systemic anti-infective treatment occurs within 14 days before the first administration of the drug; except for receiving preventive antibiotic treatment (such as prevention of urinary tract infection or chronic obstructive pulmonary disease).
• Have received other antibody/drug treatments for immune checkpoints in the past, such as PD-1, PD-L1, CTLA4 and other treatments.
• Are receiving other clinical research treatments, or the planned start of this research treatment is less than 14 days from the end of the previous clinical research treatment.
• Known to have a history of severe allergies to any monoclonal antibodies or study drug excipients.
• Known history of psychotropic drug abuse or drug use; patients who have stopped drinking can be included in the group.
• There are patients who may increase the risk of participating in research and research medication, or other severe, acute and chronic diseases, who are not suitable for participating in clinical research based on the judgment of the investigator.
