Spots Global Cancer Trial Database for Study of Efficacy and Safety of Dabrafenib Plus Trametinib in Previously Treated Patients With Locally Advanced or Metastatic, Radio-active Iodine Refractory BRAFV600E Mutation-positive Differentiated Thyroid Cancer

Study Description

Brief Summary: 150 adults patients with locally advanced or metastatic BRAFV600E mutation-positive, differentiated thyroid carcinoma who are refractory to radioactive iodine and have progressed following prior VEGFR targeted therapy will enter in the trial. Patients will be randomized in a 2:1 ratio to either dabrafenib plus trametinib or placebo. Patients will be stratified by number of prior VEGFR targeted therapy (1versus2) and prior lenvatinib treatment (yes versus no)

Detailed Description: This is a global, multicenter, randomized, double-blind, placebo-controlled phase III study to evaluate the efficacy and safety of dabrafenib plus trametinib in adult patients with locally advanced or metastatic BRAFV600E mutation-positive, differentiated thyroid cancer who are refractory to radioactive iodine and have progressed following prior VEGFR targeted therapy. After eligibility assessment, approximately 150 patients will be randomized in a 2:1 ratio to either dabrafenib plus trametinib or placebo. Patients will receive dabrafenib in combination with trametinib or placebo until disease progression as per RECIST 1.1 as determined by investigator and confirmed by BIRC or loss of clinical benefit as determined by investigator, death, unacceptable toxicity, pregnancy, withdrawal of consent, lost to follow-up or early termination of the study by the sponsor. Patients randomized in the placebo arm and for whom progression as per RECIST 1.1 is confirmed by blinded independent review committee and who meet the criteria will be given the option to cross over to the open label combination drug dabrafenib plus trametinib
