1.Primary Outcome
Title Non-progression Rate Based on RECIST 1.0 Criteria (CR+PR+SD)
Hide Description

4-mo non-progression rate

"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; Progression, as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression

2.Secondary Outcome
Title Response Per Choi Criteria
Hide Description

Response per Choi criteria

  • Complete response - Disappearance of all lesions; no new lesion
  • Partial response - A decrease in size of > or = 10% or a decrease in tumor density (HU) > or = 15% on CT. No new lesions. No obvious progression of nonmeasurable disease.
  • Stable disease - Does not meet the criteria for CR, PR, or PD. No symptomatic deterioration attributed to tumor progression.
  • Progressive disease - An increase in tumor size of > or = 10% and does not meet criteria of PR by tumor density (HU) on CT. New lesions. New intratumoral nodules or increase in the size of the existing intratumoral nodules.
Time Frame 6 months

No data displayed because Outcome Measure has zero total analyzed.
Time Frame All adverse events (related and unrelated) occurring during the study (from the time the patient receives the first dose of study drug) and up to 30 days after the last dose of study medication were reported. These were captured every months at clinic visit and patients also could report in between visits.
Adverse Event Reporting Description Patients were asked about adverse events at every clinic visit.
