Arm Intervention/treatment
Experimental: Selumetinib
Selumetinib plus Radioactive Iodine Therapy
Drug: Selumetinib
3 capsules of 25 mg strength orally twice a day for approximately 5 weeks treatment period

Drug: Radioactive Iodine Therapy
A single oral radioactive iodine dose of 100 mCI(3.7 GBq) 131I (+/-10% at the time of administration)to be administered 30 days after randomization. Additionaly, Thyrogen (Recombinant human TSH) will be used to stimulate iodine uptake according to the manufacturer's recommendation(0.9 mg intramuscular injection once a day for the 2 days prior to the dose of radioactive iodine)

Placebo Comparator: Placebo
Placebo plus Radioactive Iodine Therapy
Drug: Placebo
3 capsules ( to match Selumetinib capsules) orally twice a day for approximately 5 weeks treatment period

Drug: Radioactive Iodine Therapy
A single oral radioactive iodine dose of 100 mCI(3.7 GBq) 131I (+/-10% at the time of administration)to be administered 30 days after randomization. Additionaly, Thyrogen (Recombinant human TSH) will be used to stimulate iodine uptake according to the manufacturer's recommendation(0.9 mg intramuscular injection once a day for the 2 days prior to the dose of radioactive iodine)




Primary Outcome Measures :
  1. Complete Remission Rate (Expressed as Percentage of Patients in Complete Remission) at 18 Months Post-RAI Treatment; ITT Analysis Set [ Time Frame: At 18 months post-RAI treatment ]

    Patients were defined to be in complete remission if all of the following criteria were demonstrated:

    1. Serum thyroglobulin (Tg) levels <1 nanograms / millilitre (ng/mL) during rhTSH stimulation, in the absence of interfering Tg antibodies, as assessed by standardised central laboratory analysis.
    2. No confirmed evidence of thyroid cancer on neck ultrasound, as assessed by investigator site review.
    3. No confirmed radiological evidence of thyroid cancer, as assessed by blinded independent central review.
    4. No histopathological evidence of thyroid cancer on fine needle aspiration (FNA)/biopsy when performed, as assessed by investigator site review.
    5. No further thyroid cancer therapy was administered in the first 18 months following the initial RAI treatment.


Secondary Outcome Measures :
  1. Complete Remission Rate (Expressed as Percentage of Patients in Complete Remission) at 18 Months Post-RAI Treatment; Subgroup Analysis BRAF/NRAS Mutation Positive [ Time Frame: At 18 months post-RAI treatment ]

    Patients were defined to be in complete remission if all of the following criteria were demonstrated:

    1. Serum Tg levels <1 ng/mL during rhTSH stimulation, in the absence of interfering Tg antibodies, as assessed by standardised central laboratory analysis.
    2. No confirmed evidence of thyroid cancer on neck ultrasound, as assessed by investigator site review.
    3. No confirmed radiological evidence of thyroid cancer, as assessed by blinded independent central review.
    4. No histopathological evidence of thyroid cancer FNA/biopsy when performed, as assessed by investigator site review.
    5. No further thyroid cancer therapy was administered in the first 18 months following the initial RAI treatment.

  2. Clinical Remission Rate (Expressed as Percentage of Patients in Clinical Remission) at 18 Months Post-RAI Treatment; ITT Analysis Set [ Time Frame: At 18 months post-RAI treatment ]

    Patients were defined to be in clinical remission if all of the following criteria were demonstrated:

    1. Serum Tg levels <1 ng/mL during rhTSH stimulation, in the absence of interfering Tg antibodies, as assessed by standardised central laboratory analysis.
    2. No confirmed evidence of thyroid cancer on neck ultrasound, as assessed by investigator site review.
    3. No evidence of thyroid cancer on diagnostic whole body scan (WBS), as assessed by blinded independent central review.
    4. No histopathological evidence of thyroid cancer on FNA/biopsy when performed to clarify equivocal ultrasound findings, as assessed by investigator site review.
    5. No further thyroid cancer therapy was administered in the first 18 months following the initial RAI treatment.

  3. Clinical Remission Rate (Expressed as Percentage of Patients in Clinical Remission) at 18 Months Post-RAI Treatment; Subgroup Analysis BRAF/NRAS Mutation Positive [ Time Frame: At 18 months post-RAI treatment ]

    Patients were defined to be in clinical remission if all of the following criteria were demonstrated:

    1. Serum Tg levels <1 ng/mL during rhTSH stimulation, in the absence of interfering Tg antibodies, as assessed by standardised central laboratory analysis.
    2. No confirmed evidence of thyroid cancer on neck ultrasound, as assessed by investigator site review.
    3. No evidence of thyroid cancer on diagnostic WBS, as assessed by blinded independent central review.
    4. No histopathological evidence of thyroid cancer on FNA/biopsy when performed to clarify equivocal ultrasound findings, as assessed by investigator site review.
    5. No further thyroid cancer therapy was administered in the first 18 months following the initial RAI treatment.
