Clinical trials are an important way to improve treatment for people with cancer. While most are continuing during the COVID-19 pandemic, the period of time that clinical trials are available and recruiting may change quickly. If you would like to get involved in a clinical trial, speak to your treatment team or the health service where the clinical trial is being undertaken, to confirm it is open and appropriate for you. For cancer information and support, call Cancer Council's experienced cancer nurses on 13 11 20 Monday to Friday from 9am-5pm.

Trial Overview Read MoreRead more

This phase II trial will use Dabrafenib and/or Trametinib to enhance treatment for people with thyroid cancer who no longer respond to radioactive iodine (a standard treatment for people with this type of cancer).
 

This trial is treating patients with radioiodine refractory thyroid cancer.

This is a systemic therapy trial.

You may be able to join this trial if:

  • You are able to swallow medication by mouth.

You may be excluded from this trial if:

  • You have a certain disease or psychological condition.

Summary

This is a non-randomised, open-label study for adults with radioiodine refractory differentiated thyroid cancer with BRAF V600E or NRAS mutations. 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. During Days 1-30, participants with BRAF V600E mutations will then receive Dabrafenib (oral, 150mg twice daily) and Trametinib (oral, 2mg once daily); and participants with RAS mutations will receive Trametinib (oral, 2mg once daily). All participants will then receive 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.
