Primary Outcome Measures:
  • Progression-Free Survival (PFS) [ Time Frame: from enrollment to disease progress or death ] [ Designated as safety issue: No ]
    The period from study entry until disease progression, death or date of last contact.

Secondary Outcome Measures:
  • Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs); [ Time Frame: from signing the consent form to 28 days after end of study treatment ] [ Designated as safety issue: Yes ]
    Counts of participants who had treatment-emergent adverse events (TEAEs), defined as newly occurring or worsening after first dose. Relatedness to [study drug] was assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category were counted once within the category.Type, incidence, severity graded by [NCI] CTCAE, timing, seriousness, and relatedness of adverse events, laboratory abnormalities, physical examination findings, vital signs, weight and ECOG

  • Overall survival (OS) [ Time Frame: from enrollment to death ] [ Designated as safety issue: No ]
  • Overall objective response rate (ORR) [ Time Frame: from enrollment to objective response ] [ Designated as safety issue: No ]
  • Time to tumor response (TTP) [ Time Frame: from enrollment to objective response ] [ Designated as safety issue: No ]

Enrollment: 60
Study Start Date: November 2008
Study Completion Date: June 2014
Primary Completion Date: April 2014 (Final data collection date for primary outcome measure)
