Brief Summary:
The purpose of this study is to learn how hereditary or sporadic medullary thyroid cancer patients, treated with ZD6474, react to the drug, what happens to ZD6474 in the human body, about the side effects of ZD6474, and if ZD6474 can decrease or prevent the growth of tumors.

Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Progression-Free Survival(PFS) [ Time Frame: RECIST tumour assessments were performed at screening (within 3 weeks before date of randomisation), then once every 12 weeks up to and including discontinuation of blinded study treatment, unless patients had withdrawn consent. ]
    Median time to progression (months) 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. Values here are estimated (from a Weibull model) as the medians were not met.


Secondary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: RECIST assessments performed at screening (within 3 weeks before randomisation), then every 12 weeks. For patients with objective response of CR or PR, an additional confirmatory scan was performed ≥4 weeks following the date of first response. ]

    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.


  2. Disease Control Rate (DCR) [ Time Frame: RECIST tumour assessments were performed at screening (within 3 weeks before date of randomisation), then once every 12 weeks up to and including discontinuation of blinded study treatment, unless patients had withdrawn consent ]
    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) >= 12 weeks

  3. Duration of Response (DoR) [ Time Frame: RECIST tumour assessments were performed at screening (within 3 weeks before date of randomisation), then once every 12 weeks up to and including discontinuation of blinded study treatment, unless patients had withdrawn consent ]
    Response is defined as a confirmed best objective response of CR or PR. Duration of response is defined as time from the date of first documented response until date of documented progression or death in the absence of disease progression (provided death is within 3 months of last RECIST assessment). Values are estimated as the medians weren't met

  4. Overall Survival (OS) [ Time Frame: Number of deaths since randomisation ]
    As data was immature at data cut off, number of death events is quoted

  5. Biochemical Response Calcitonin (CTN) [ Time Frame: Blood samples Blood samples for analysis of CTN were taken at screening baseline (average of 0, 1, 4 and 8 hours), then every 4 weeks until discontinuation and 60 day follow up ]
    Best biochemical response was calculated from assessments 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. CR and PR being defined according to level of CTN.

  6. Biochemical Response Carcinoembryonic Antigen (CEA) [ Time Frame: Blood samples for analysis of CEA were taken at screening baseline (average of 0, 1, 4 and 8 hours), then every 4 weeks until discontinuation and 60 day follow up ]
    Best biochemical response was calculated from assessments 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. CR and PR being defined according to level of CEA.

  7. Time to Worsening of Pain (TWP) [ Time Frame: During the last week of the screening period (Day -7 to Day 0), the brief pain inventory (BPI) and opioid analgesic use were self-reported once a day for 4 days to establish baseline, then every week during blinded study treatment, up to discontinuation. ]
    TWP was derived using the worst pain score from brief pain inventory (BPI) and patient reported opioid analgesic use. BPI uses 0 to 10 numeric rating scales asking subjects to rate their pain.
