A study to learn how hereditary and sporadic 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 tumour growth.

An International, Phase III, Randomized, Double-Blinded, Placebo-Controlled, Multi-Center Study to Assess the Efficacy of ZD6474 (ZACTIMA ) versus Placebo in Subjects with Unresectable Locally Advanced or Metastatic Medullary Thyroid Cancer.

Primary

MeasureTime frame
Main Objective: To demonstrate an improvement in progression-free survival (PFS) with ZD6474 as compared to placebo in subjects with unresectable locally advanced or metastatic MTC;Secondary Objective: 1. To demonstrate an improvement in the overall objective response rate (ORR), disease control rate (DCR), and duration of response (DOR) with ZD6474 as compared to placebo 2. To demonstrate an improvement in the overall survival (OS) in subjects with MTC who have been treated with ZD6474 as compared to placebo 3. To demonstrate an improvement in biochemical response with ZD6474 as compared to placebo as measured by calcitonin (CTN) and carcinoembryonic antigen (CEA) 4. To demonstrate a delay in time to worsening of pain (TWP) among subjects with MTC after treatment with ZD6474 as compared to placebo 5. To determine the pharmacokinetics (PK) of ZD6474 in this subject population and investigate any influence of subject demography and pathophysiology on the PK PLUS other secondary and exploratory objectives as detailed in the protocol;Primary end point(s): Progression free survival;Timepoint(s) of evaluation of this end point: Time to progression or death;Main Objective: To demonstrate an improvement in progression-free survival (PFS) with ZD6474 as compared to placebo in subjects with unresectable locally advanced or metastatic MTC;Secondary Objective: 1.
