Dabrafenib With or Without Trametinib in Treating Patients With Advanced Differentiated Thyroid Cancer

Summary

This randomized phase II trial studies how well dabrafenib works with or without trametinib in treating patients with recurrent thyroid cancer. Dabrafenib and trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether dabrafenib is more effective when given with or without trametinib in treating thyroid cancer

paper The objective response rate (modified RECIST) was 42% (11/26 [95% confidence interval {CI} 23-63%]) with dabrafenib versus 48% (13/27 [CI 29-68%]) with dabrafenib + trametinib (p = 0.67). PMID 35658604 ↗
