简要总结
The purpose of this study is to observe and evaluate the efficacy and safety of chidamide plus camrelizumab as second-line therapy for advanced esophageal squamous cell carcinoma treated with PD-1 blockade
详细描述
Although immune checkpoint inhibitors (ICIs) have been tested in esophageal squamous cell carcinoma(ESCC) with demonstrated clinical efficacy，a significant number of patients who have an initial response will develop a secondary resistance and relapse. recent studies on the role of epigenetics in immune evasion have exposed a key role for epigenetic modulators in augmenting the tumour microenvironment and restoring immune recognition and immunogenicity. These discoveries have established a highly promising basis for studies using combined epigenetic and immunotherapeutic agents as anti-cancer therapies. Chidamide is a novel orally active benzamide-type histone deacetylase inhibitor that has shown in vitro activities against a wide array of neoplasms. Hence, the study of chidamide plus camrelizumab as second-line therapy for advanced ESCC treated with PD-1 blockade was performed.

- •ECOG PS 0 or 1
- •Newly obtained (preferred) or archival tissue sample available
- •Negative urine or serum pregnancy test within 72 h before treatment(females)
- •Willing to use an adequate method of contraception throughout the study and for 120 days after the last dose of study medication and up to 180 days after the last dose of cisplatin
- •Adequate haematologic function, defined as ANC ≥ 1500/μl, platelet count ≥ 100,000/μl and haemoglobin ≥ 9.0 g/dl or ≥5.6 mmol/l
- •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
- •Adequate hepatic function, defined as total bilirubin ≤1.5 × ULN or direct bilirubin ≤ ULN for those with total bilirubin levels 1.5 × ULN, and ALT/AST levels ≤ 2.5 × ULN
- •Adequate coagulation function, defined as INR ≤ 1.5 × ULN unless the patient is receiving anticoagulant therapy, in which case PT or aPTT should be within the therapeutic range
- •Written informed consent
排除标准
- •Patients with evidence of fistula (either esophageal/bronchial or esophageal/aorta).
- •Evidence of complete esophageal obstruction not amenable to treatment.
- •Active leptomeningeal disease or uncontrolled, untreated brain metastasis.
- •Active autoimmune diseases or history of autoimmune diseases that may relapse
- •Any active malignancy ≤ 2 years before randomization except for the specific cancer under investigation in this study and any locally recurring cancer that has been treated curatively (eg, resected basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix or breast).
- •Uncontrolled diabetes or > Grade 1 laboratory test abnormalities in potassium, sodium, or corrected calcium despite standard medical management or ≥ Grade 3 hypoalbuminemia ≤ 14 days before treatment.
- •Uncontrollable pleural effusion, pericardial effusion, or ascites requiring frequent drainage (recurrence within 2 weeks after intervention).
- •History of interstitial lung disease, noninfectious pneumonitis or uncontrolled lung diseases including pulmonary fibrosis, acute lung diseases, etc.
- •Infection (including tuberculosis infection, etc) that requires systemic antibacterial, antifungal or antiviral therapy within 14 days before treatment.
- •A history of severe hypersensitivity reactions to chidamide and monoclonal antibodies.
- •Patients with toxicities (as a result of prior anticancer therapy) that have not recovered to ≤Grade 2 or stabilized, except for AEs not considered a likely safety risk (eg, alopecia, neuropathy, and specific laboratory abnormalities).
