This multicenter, open-label phase 2 trial assessed the efficacy and safety of encorafenib plus binimetinib (ENC + BIN) in 22 patients with unresectable BRAF V600-mutated thyroid cancer. The objective response rate (ORR) increased to 68.2% after a median follow-up of 28.7 months, indicating sustained tumor responses.

Key findings

  • The objective response rate (ORR) for ENC + BIN was 68.2% in patients with BRAF V600-mutated thyroid cancer.
  • Median progression-free survival (PFS) was not reached for differentiated thyroid carcinoma (DTC).
  • Median overall survival (OS) was 17.7 months for anaplastic thyroid carcinoma (ATC).
  • Common adverse events included eye disorders (5/12) and infections (4/12) after > 360 days.

Why it matters

The findings suggest that ENC + BIN may offer a viable treatment option for patients with BRAF V600-mutated thyroid cancer, particularly those who are refractory to other therapies, highlighting the need for ongoing management strategies in this population.
