Eur Thyroid JPublished Secondary analysis of a phase 2 single-arm trial

Authors' conclusion

The combination therapy of encorafenib plus binimetinib for unresectable BRAF V600E-mutated thyroid cancer was associated with generally maintained HR-QoL. Considering the efficacy and safety data from the trial, the regimen may provide clinical benefits while maintaining HR-QoL.
