E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the efficacy (as assessed by progression free survival (PFS)) of vandetanib when compared to placebo in patients with papillary or poorly differentiated thyroid cancer that is either locally advanced or metastatic who are refractory or unsuitable for radioiodine therapy. |

To determine the efficacy of vandetanib when compared to placebo in this patient population as assessed by efficacy variables including duration of response (DOR), objective response rate (ORR), change in tumour size (TS) and overall survival (OS). 2. To evaluate the pharmacokinetics (PK) of vandetanib in this patient population and potentially investigate any influence of patient demography and pathophysiology on vandetanib PK. 3. To demonstrate an improvement in time to worsening of pain (TWP) in patients treated with vandetanib when compared to placebo in this patient population. 4. To evaluate the safety and tolerability of vandetanib treatment in this patient population. |

Determinar la eficacia de vandetanib en comparación con placebo en esta población de pacientes, evaluada mediante variables de eficacia, como la duración de la respuesta (DdR), la tasa de respuestas objetivas (TRO), el cambio en el tamaño tumoral (TT) y la supervivencia global (SG). 2. Evaluar la farmacocinética (FC) de vandetanib en esta población de pacientes y potencialmente investigar cualquier influencia de los datos demográficos de los pacientes y de la fisiopatología sobre la FC de vandetanib. 3. Demostrar una mejoría de tiempo hasta el empeoramiento del dolor (TED) en pacientes tratados con vandetanib en comparación con placebo en esta población de pacientes. 4. Evaluar la seguridad y tolerabilidad del tratamiento con vandetanib en esta población de pacientes. |
