Other outcomes

  1. Tumor Response Assessment for Measurable Lesions According to RECIST, v1.1 (Response Evaluation Criteria in Solid Tumors)

    Time frame: Up to 6 months

    Positron emission tomography - computed tomography (ET-CT), CT, or magnetic resonance imaging (MRI) scans of all anatomic regions involved with the disease were performed to assess tumor response using the Response Evaluation Criteria in Solid Tumors, Version 1.1. (RECIST v1.1). Bone metastases were assessed by bone scintigraphy (bone scan). Tumor measurements and evaluation of tumor response were performed at baseline and within the last 7 days of Cycle 2. Thereafter, if subjects continued regorafenib treatment, tumor assessments were performed after every third cycle and at the end-of-treatment (EOT) visit. In addition, outcome of "Assessment of Bone Metastases by Scintigraphy if Applicable (Bone Scan)" was registered, the results of which has been reported as tumor response in this outcome as well.
