研究概览
简要总结
The purpose of this study is to evaluate the safety and efficacy of CC-486 in previously treated patients with locally advanced or metastatic nasopharyngeal carcinoma having failed one to two previous regimens, including platinum-based chemotherapy. Participants will be enrolled according to a Simon two-stage design; if the predefined activity is met (>4 responses [complete response; partial response {CR/PR}] out of the first 17 evaluable participants based on independent radiological assessment), then the study will continue to enroll an additional 34 participants. If 4 or less responses out of 17 are observed, then the study enrollment will be stopped.

研究组 & 干预措施
CC-486
CC-486 will be administered orally every day on Days 1-14 of a 21 day cycle at a dose of 300 mg. The first 6 participants of Asian-Pacific ethnicity will receive a starting dose of 200 mg. If there are no safety concerns, the 300 mg dose will be administered to all subsequent participants of Asian-Pacific ethnicity.
干预措施: CC-486 (Drug)
结局指标
主要结局
Percentage of Participants Who Achieved a Complete or Partial Response According to Response Evaluation Criteria in Solid Tumors (RECIST 1.1) Based on an Independent Radiology Assessment (IRA)
时间窗: Tumor response was assessed every (Q) 6 weeks for the first 3 evaluations then Q 9 weeks until disease progression as of the cut-off date of 08 August 2017; the median duration of treatment was 257 days for the 200 mg dose and 114.5 days for 300 mg dose
Overall response rate was defined as the combined incidence of Complete Response (CR) or Partial Response (PR), confirmed no less than 4 weeks after the criteria for response were first met, based on independent radiology assessment according to RECIST 1.1 criteria. Complete response was defined as the disappearance of all target lesions and non-target lesions; Partial response is at least a 30% decrease from baseline in the sum of diameters of target lesions with no progression of non-target lesions and no new lesions or disappearance of target lesions with persistence of one or more non-target lesions from baseline.
Kaplan Meier Estimate of Progression-Free Survival (PFS) Based on an Independent Radiology Assessment According to RECIST 1.1 Criteria
时间窗: From Day 1 of documented disease progression; up to data cut off date of 08 August 2017; median follow-up time for censored participants was 12.3 months
PFS was defined as the time from the date of start of the study treatment to the date of disease progression or death (any cause) on or prior to the data cut-off date for the statistical analysis, whichever occurred earlier, based on an independent radiology assessment of response using RECIST v1.1 criteria. Progressive disease was defined as at least a 20% increase in the sum of diameters of target or non-target lesions from nadir or appearance of a new lesion.
