Outcome Measures
Primary Outcomes (1)
Objective Response Rate (ORR) Based on Blinded Independent Central Review (BICR) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
ORR based on BICR was defined as the percentage of participants with best overall response (BOR) of complete response (CR) plus partial response (PR). CR: Disappearance of all target non-nodal lesions. Any target lymph node must have had a reduction in short axis to \<10 mm, NOT total disappearance. PR: At least a 30% decrease in the sum of the diameters of target lesions, taken as reference the baseline sum of diameters. The percentage of participants who experience a CR or PR as assessed by BICR based on RECIST 1.1 is presented.
From first dose of trial drug up to a minimum of last dose + 65 days or data cutoff date; median (min, max) time on trial was 3.4 (2.2, 6.5) months at data cut off

- Time Frame
- Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.
- Access Criteria
- Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
