31975 29399853 A synergistic effect of the combination of dabrafenib and trametinib, via concomitant inhibition of the ERK, was observed in BRAF V600-mutant melanoma cell lines, and delayed emergence of resistance was observed in BRAF V600-mutant melanoma xenografts in vivo along with a decrease in skin toxicities compared with monotherapy.16 In a phase 2 study, the dabrafenib and trametinib combination significantly improved PFS and decreased the frequency of known BRAF inhibitor-induced hyperproliferative skin lesions such as cutaneous squamous cell carcinoma, papilloma and hyperkeratosis, compared with dabrafenib monotherapy in patients with BRAF inhibitor-naive metastatic melanoma.17 The combination of dabrafenib and trametinib in the pivotal phase 3 studies revealed statistically significant and clinically relevant improvements in PFS, overall survival (OS) in patients with BRAF V600 mutation-positive melanoma.18, 19, 20, 21 As the data in Asian patients are very limited, this study was conducted to determine the safety and preliminary efficacy of dabrafenib plus trametinib in Japanese patients with BRAF V600E/K mutation-positive solid tumors, including

We found that FAKi reduces both UM tumor size and cell proliferation in two different UM tumor models, the latter clearly visible by Ki67 staining that was nearly absent in VS-4718 treated mice (Fig.

type specifically driven by few activating (Galphaq) mutations may serve as a good testbed for studying such an approach, harnessing a novel SL-based integrated bioinformatics analysis to uncover novel oncogenic signaling mechanisms controlled by Galphaq and target them.
