Study: NCT01586624

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: Vandetanib, Selumetinib
Description: Cycle 1: Vandetanib higher (lead in) dose of 300 mg OD (Days 1 to 4) followed by vandetanib steady state dose of 100 mg OD (Days 5 to 14) followed by vandetanib steady state dose of 100 mg OD + 25 mg of selumetinib BD (28 days). Cycle 1 is 42 days long.~Cycle 2 onwards: Vandetanib steady state dose of 100 mg OD + 25 mg of selumetinib BD (28 days). From Cycle 2, cycles are 28 days long.~Patients will be allowed to receive 6 cycles. If the patient is still benefiting clinically with no unacceptable toxicity, then the Investigator can ask the Sponsor for continuation of treatment.
