Primary Outcome Measures:
  • Objective Response Rate (ORR) [ Time Frame: RECIST assessed at screening (up to 3 weeks prior to first dose), then every 12 weeks (± 2 weeks), from date of first dose to objective progression, up to and including discontinuation of study treatment. ] [ Designated as safety issue: No ]

    The ORR is the number of patients that are responders ie those patients with a confirmed best objective response of complete response (CR) or partial response (PR) as defined by RECIST criteria.

    The categories for best objective response are CR, PR, stable disease (SD)>= 12 weeks, progressive disease (PD) or NE.



Secondary Outcome Measures:
  • Progression-Free Survival (PFS) [ Time Frame: RECIST assessed at screening (up to 3 weeks prior to first dose), then every 12 weeks (± 2 weeks), from date of first dose to objective progression, up to and including discontinuation of study treatment. ] [ Designated as safety issue: No ]
    Median progression free survival (months) estimated from a Weibull model with corresponding 95% confidence intervals. Progression free survival is the time from randomisation until objective disease progression (determined by RECIST assessments) or death (by any cause in the absence of objective progression) provided death is within 3 months from the last evaluable RECIST assessment.

  • Disease Control Rate (DCR) [ Time Frame: RECIST assessed at screening (up to 3 weeks prior to first dose), then every 12 weeks (± 2 weeks), from date of first dose to objective progression, up to and including discontinuation of study treatment. ] [ Designated as safety issue: No ]
    Disease control rate is defined as the number of patients who achieved disease control at 8 weeks following randomisation. Disease control at 8 weeks is defined as a best objective response of complete response (CR), partial response (PR) or stable disease (SD) >= 24 weeks

  • World Heath Organization (WHO) Performance Status [ Time Frame: WHO PS assessed at screening (up to 3 weeks prior to first dose), baseline and then every 12 weeks (± 2 weeks), up to and including discontinuation of study treatment. ] [ Designated as safety issue: No ]
    Number of patients demonstrating an improvement from baseline to 24 weeks in WHO PS. Where WHO PS is the standard scale with patients scored (0 healthy - 5 dead) based on their physical capabilities

  • Symptomatic Response [ Time Frame: Symptomatic diarrhea was assessed using stool frequency diaries. Baseline was established using the average of the 4 days immediately prior to first dose, then weekly until discontinuation of study treatment. ] [ Designated as safety issue: No ]
    Symptomatic response will be defined as at least a 50% decrease in the stool frequency (represented by a persistent decrease in stool frequency over 4 weeks), taking as reference the baseline (mean) level.

  • Biochemical Response Calcitonin (CTN ) [ Time Frame: Blood samples for analysis of CTN were taken at screening (0, 1, 4, and 8 hours to determine the baseline CTN/CEA level) then every 4 weeks until discontinuation Time point(s) at which outcome measure was assessed. (Limit: 255 characters) ] [ Designated as safety issue: No ]
    A patient's best biochemical response was calculated from assessments performed at baseline and during treatment. Responders were those patients with a best biochemical response of CR or PR, confirmed by repeat assessments, which were to be performed no less than 4 weeks after the criteria for PR or CR were first met.

  • Biochemical Response Carcinoembryonic Antigen CEA) [ Time Frame: Blood samples for analysis of CTN were taken at screening (0, 1, 4, and 8 hours to determine the baseline CTN/CEA level) then every 4 weeks until discontinuation ] [ Designated as safety issue: No ]
    A patient's best biochemical response was calculated from assessments performed at baseline and during treatment. Responders were those patients with a best biochemical response of CR or PR, confirmed by repeat assessments, which were to be performed no less than 4 weeks after the criteria for Partial Response (PR) or Complete Response (CR) were first met.
