Drug: VEGFR inhibitor
VEGFR inhibitor Drug: Chemotherapy chemotherapy |
- Objective Response Rate (CR+PR) [ Time Frame: 6 months ]Objective Response Rate as defined by RECIST 1.1 after induction therapy followed by definitive chemoradiation. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) 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; Objective Response (OR) = CR + PR.
- Number of Participants With at Least One Grade 3-4 Toxicity [ Time Frame: 6 months ]Toxicity will be assessed according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.
- Progression-Free Survival [ Time Frame: 6 months ]Time to death or progression defined by imaging of target lesions via CT or MRI scan every 3 months.
