33 pts with non-small cell lung cancer (NSCLC) have been evaluated for response. The objective response rate (ORR) was 60.6% (95%CI: 42.1%, 77.1%), a median duration of response (DoR) was 11.3 months (95% CI: 3.9, NE), and a median progression free survival (PFS) was 11.7 months (95% CI: 5.6, NE)....Tunlametinib in combination with vemurafenib showed promising antitumor activity and manageable safety profile in pts with BRAF V600-mutated solid tumors.
