At the first stage analysis, overall response, at least 1 response out of 12 patients will need to be observed to continue through the second stage. At the second stage, at least 4 responses out of 37 patients will need to be observed to accept the treatment. The overall power for overall response rate is 90%. The overall type I error, the chance of incorrectly rejecting the null hypothesis is 9%. The probability of stopping at the first stage under the null hypothesis is 54%. The operating characteristics of this design are calculated using the exact binomial distribution.","groups":[{"description":"Patients receive nivolumab IV over approximately 60 minutes once every 2 weeks for up to 46 doses in the absence of disease progression or unacceptable toxicity.\n\nLaboratory Biomarker Analysis: Correlative studies\n\nNivolumab: Given IV","id":"OG000","title":"Cohort A (Nivolumab - Closed to Accrual on 21-Oct-2015)"}],"paramType":"COUNT_OF_PARTICIPANTS","populationDescription":"Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \\>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.","reportingStatus":"POSTED","timeFrame":"Up to 100 days","title":"Objective Response Per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 Among Patients With Advanced Leiomyosarcoma of the Uterus (ULMS) Treated With Nivolumab (Cohort A)","type":"PRIMARY","unitOfMeasure":"Participants"}
