Brief Summary

The purpose of this study is to observe and evaluate the efficacy and safety of Decitabine plus Penpulimab as second-line therapy for advanced esophageal squamous cell carcinoma treated with PD-1 blockade

Detailed Description

Although immune checkpoint inhibitors (ICIs) have been tested in esophageal squamous cell carcinoma(ESCC) with demonstrated clinical efficacy，a significant number of patients 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. Decitabine 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 decitabine plus penpulimab(AK-105) as second-line therapy for advanced ESCC treated with PD-1 blockade was performed.

8. Negative urine or serum pregnancy test within 72 h before randomization (females)

9. 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

10. Adequate haematologic function, defined as ANC ≥ 1500/μl, platelet count ≥ 100,000/μl and haemoglobin ≥ 9.0 g/dl or ≥5.6 mmol/l

11. 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

2. Evidence of complete esophageal obstruction not amenable to treatment.

3. Active leptomeningeal disease or uncontrolled, untreated brain metastasis.

4. Active autoimmune diseases or history of autoimmune diseases that may relapse

5. 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).

6. 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 initial treatment .

7. Uncontrollable pleural effusion, pericardial effusion, or ascites requiring frequent drainage (recurrence within 2 weeks after intervention).

9. Infection (including tuberculosis infection, etc) that requires systemic antibacterial, antifungal or antiviral therapy within 14 days beforeinitial treatment

10. A history of severe hypersensitivity reactions to chidamide and monoclonal antibodies.

11. 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).
