NCT06475989

Brief Summary

This phase III trial compares the effect of cabozantinib versus combination dabrafenib and trametinib for the treatment of patients with differentiated thyroid cancer that does not respond to treatment (refractory) and which expresses a BRAF V600E mutation. Cabozantinib is in a class of medications called receptor tyrosine kinase inhibitors. It binds to and blocks the action of several enzymes which are often over-expressed in a variety of tumor cell types. This may help stop or slow the growth of tumor cells and blood vessels the tumor needs to survive. Dabrafenib is an enzyme inhibitor that binds to and inhibits the activity of a protein called B-raf, which may inhibit the proliferation of tumor cells which contain a mutated BRAF gene. Trametinib is also an enzyme inhibitor. It binds to and inhibits the activity of proteins called MEK 1 and 2, which play a key role in activating pathways that regulate cell growth. This may inhibit the growth of tumor cells mediated by these pathways. The usual approach for patients with thyroid cancer is targeted therapy with dabrafenib and trametinib. This trial may help researchers decide which treatment option (cabozantinib alone or dabrafenib in combination with trametinib) is safer and/or more effective in treating patients with refractory BRAF V600E-mutated differentiated thyroid cancer.

Outcome Measures

Primary Outcomes (1)

  • Progression free survival (PFS)

    PFS will be compared between the two groups using a stratified log-rank test with one-sided type I error of 0.05. Median PFS and 95% confidence interval (CI) for each treatment arm will be estimated using the Kaplan-Meier method. The stratified hazard ratio and 95% CI will be estimated using a Cox proportional hazard model with treatment group as the independent variable.

    From randomization to radiographic progression of disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or death from any cause, up to 5 years

Secondary Outcomes (5)

  • Objective response

    Up to 5 years

  • Overall survival

    From randomization to death from any cause, up to 5 years

  • Duration of response

    From confirmed response (complete response or partial response) to progression among patients who achieve a response, up to 5 years

  • PFS2 - the time from randomization to progression on subsequent therapy or death from any cause (whichever occurs first)

    From randomization to progression on subsequent therapy or death from any cause, up to 5 years

  • Incidence of adverse events

    at 2 weeks, 4 weeks, 8 weeks, 16 weeks, and then every 12 weeks after the 16-week confirmatory scan

Other Outcomes (1)

  • Patient tolerability

    At baseline, 4, 8, 16, and 28 weeks

Study Arms (2)

Arm A (Dabrafenib and trametinib)

ACTIVE COMPARATOR

Patients receive dabrafenib PO BID and trametinib PO QD on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan, blood sample collection and may undergo MRI throughout the study.

EXPERIMENTAL

Patients receive cabozantinib PO QD on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan, blood sample collection and may undergo MRI throughout the study.
