Study summary

The purpose of this study is to assess the efficacy and safety of dabrafenib in combination with trametinib for treating adult patients with locally advanced or metastatic Differentiated Thyroid Cancer (DTC) harboring the BRAFV600E mutation, who are refractory to radioactive iodine (RAI) therapy and have experienced disease progression following one or two prior VEGFR-targeted treatments.

Key Inclusion Criteria: * Signed informed consent * Male or female ≥ 18 years of age at time of informed consent * Histologically or cytologically confirmed diagnosis of advanced/metastatic differentiated thyroid carcinoma * Radioactive-iodine refractory disease * BRAF V600E mutation-positive tumor sample as per central laboratory result * Has progressed on at least 1 but not more than 2 prior VEGFR targeted therapies * Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 * At least one measurable lesion as defined by RECIST v1.1. Key Exclusion Criteria: * Anaplastic or medullary carcinoma of the thyroid * Previous treatment with a BRAF inhibitor and/or a MEK inhibitor * Concomitant RET Fusion-Positive Thyroid Cancer * Treatment with any type of small molecule kinase inhibitor (including investigational kinase inhibitor) within 2 weeks before randomization * Treatment with any type of anticancer antibody (including investigational antibody) or systemic chemotherapy within 4 weeks before randomization * Treatment with radiation therapy for bone metastasis within 2 weeks or any other radiation therapy within 4 weeks before randomization * A history or current evidence/risk of retinal vein occlusion (RVO) or central serous retinopathy Other inclusion/exclusion criteria may apply.

Primary outcome measure(s)

  • Progression Free Survival (PFS) — From randomization to first documented progression or deaths, whichever comes first, assessed up to approximately 3 years
    Progression Free Survival (PFS) was defined as the time from the date of randomization to the date of the first documented progression according to RECIST 1.1 based on Blinded Independent Review Committee (BIRC) assessment, or death due to any cause. The primary analysis was conducted after all patients had either completed a minimum of 16 weeks of treatment or discontinued earlier, and following the occurrence of approximately 95 PFS events (Data cut-off date for the primary analysis was 22 January 2025).
