This phase 2 clinical trial evaluated the efficacy of lenvatinib plus pembrolizumab in 25 patients with non-BRAF mutated anaplastic thyroid cancer (ATC). The study found a median overall survival (OS) of 13 months, significantly improving upon the historical median OS of 3 months with lenvatinib alone.
Key findings
- Median overall survival was 13 months (95% CI: 7.8-35.6; p<0.01).
- Median progression-free survival was 5.4 months (95% CI: 3.8-11.0).
- The best overall response rate in target lesions was 36%, including 1 complete and 8 partial responses.
Why it matters
The study highlights a potential treatment option for patients with non-BRAF mutated ATC, a group historically facing limited effective therapies. Improved survival outcomes may influence treatment strategies in this challenging population.
