Outcomes
Primary Outcomes
Response Rates of Radiographically Measurable Disease
Time Frame: Disease response assessed after every 2 Treatment Cycles, or around 8 weeks.
The primary outcome measure will be the response rates of radiographically measurable disease. Response rate of disease will be assessed per Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT scan: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), \>= 30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD), \>= 20% increase in the sum of the longest diameter of target lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease.
Secondary Outcomes
- Second-line Progression Free Survival(Upon completion of follow-up, for an average of 99 days following the initiation of study treatment.)
- Time to Second Progression (From Start of First-Line Regimen)(Documented by Follow-up CT scans following first line treatment, average of 225 days.)
