Phase II Multicenter Open-Label Single-Arm Study of Decitabine Combined With Oxaliplatin in Patients With Relapsed/Metastatic Renal Cell Carcinoma

CHUCAS-025 (Cancer Hospital, University of Chinese Academy of Sciences) is a phase II trial conducted at 3 investigative centres in the Zhejiang Province, China. Eligible patients are 18 to 75 years old with relapsed/metastatic renal cell carcinoma progressed on standard of care. Patients receive Decitabine 10 mg/day for 5 consecutive days (d1-5) plus Oxaliplatin 75mg/m2 2-week-cycle (d6, d20) within 4 weeks. One cycle is defined as 4 weeks of treatment and total of 6 cycles are designed for patients. Patients who experienced unacceptable toxicities or clinical or documented progressive disease are discontinued from the study. The duration of any objective response is measured from the date the initial response is observed to the date that disease progression is observed. Patients receiving 2 cycles of treatment are considered evaluable for response using Response Evaluation Criteria in Solid Tumors (RECIST). Disease assessment by the investigator include response assessment and diagnostic imaging and measuring of target lesions. All patients receive computed tomography and/or magnetic resonance imaging scans for assessing disease status. All patients were followed up until death from any cause.
