Description of intervention(s) / exposure
Treatment: Drugs - Dabrafenib 75 MG
Treatment: Drugs - Trametinib 2 MG

Experimental: BRAFv600E mutant radioiodine refractory thyroid cancer - Prior to commencing interventional treatment, participants will commence a low iodine diet and undergo thyroxine withdrawal and commence T3 replacement from day -27. On day -5 they will receive an oral dose of 124I (40MBq/1.08 mCi) with imaging at 24 hours (+/-6) post dose and a second imaging assessment within 120 hours.
Participants will receive Dabrafenib (oral, 150mg BD) and Trametinib (oral, 2mg OD) from day 1-30.
A second oral dose of I124 will be administered at day 24 followed by imaging at the same interval as baseline.
Participants achieving >20Gy tumour uptake of I124 will be administered 6GBq (3.3Gy/GBq) 131I, I131 wb scan and SPECT/CT will be performed within 24 hours and at hospital discharge.
Participants who do not achieve >20Gy tumour update of I-124 will move into follow up.
Follow up will occur every 12 weeks for 12 months.

Experimental: RAS mutant radioiodine refractory thyroid cancer - Prior to commencing interventional treatment, participants will commence a low iodine diet and undergo thyroxine withdrawal and commence T3 replacement from day -27. On day -5 they will receive an oral dose of 124I (40MBq/1.08 mCi) with imaging at 24 hours (+/-6) post dose and a second imaging assessment within 120 hours.
Participants will receive Trametinib (oral, 2mg OD) from day 1-30.
A second oral dose of I124 will be administered at day 24 followed by imaging at the same interval as baseline.

Eligibility
Key inclusion criteria
1. Histologically-confirmed differentiated (including poorly differentiated) thyroid
cancer that is either locally advanced or metastatic.

2. Age > 18 years.

3. Life expectancy > 12 weeks.

4. Documented radiological progression by RECIST 1.1 in last 12 months.

5. Radioiodine refractory (at least one of):

1. one measurable lesion without radioiodine uptake on 131I scan,

2. at least one measurable lesion that had progressed by RECIST criteria within 12
months of 131I therapy despite 131I avidity at time of treatment, or

3. cumulative treatment with >24 GBq (600 mCi) of 131I.

6. At least one evaluable lesion as per RECIST v1.1 that has not been treated with local
radiation therapy within 3 months prior to the first dose of TKI. Irradiated lesions
can only be included as an evaluable lesion if it has shown radiological progression
as per RECIST v1.1 on subsequent imaging following irradiation.

1. Haemoglobin = 9g/dL

2. Neutrophils = 1.5 x 109/L

3. Platelets = 100 x 109/L

4. INR = 1.4

5. Serum Creatinine = 1.3 x ULN

6. Estimated Creatinine Clearance = 30 ml/min (by Cockcroft Gault Formula)

7. Serum ALT and AST = 2.5 x ULN

8. Serum Total Bilirubin = 1.5 x ULN.

9. TSH suppression <0.1mU/L or otherwise consistent with 2015 ATA Guidelines on
Thyroid Cancer
Minimum age

Key exclusion criteria

upon discussion with the medical monitor.

5. Unstable brain metastasis. Treated or non-treated brain metastasis are allowed if
neurologically stable, asymptomatic, on a stable steroid dose for a period of 2 weeks,
and not anticipated to require any intervention during the trial treatment period. If
treated with radiation or surgery, any related AE's should have recovered to = grade 1
prior to enrolment on trial.

6. Pregnancy, breastfeeding or unwilling to use contraception in those of child-bearing
age.

7. Significant medical condition that would prevent compliance with study procedures.

8. History of retinal vein occlusion or retinopathy.

Summary
Brief summary
This prospective, multi-centre, open label, non-randomised phase II trial aims restore
radioiodine sensitivity in patients with NRAS or BRAFV600E mutant refractory thyroid cancer.

Participants will be treated with Trametinib +/- Dabrafenib tyrosine kinase inhibitors for a
period of 30 days, restoration of sensitivity will be monitored using 18F-FDG-PET & I-124 PET
imaging.
