Targeting MEK and ALK or MEK and PI3K/mTOR synergistically inhibits FM-MPeM-01 PDCs growth....strong synergy between ALK inhibitors (crizotinib and ceritinib) in combination with MEK (cobimetinib) and mTOR/PI3K (gedatolisib) inhibitors, respectively (Fig. 4). The synergy was more efficient for ceritinib compared to crizotinib. These results highlight the potential efficacy of these combinations in ALK-positive MPeM cancer treatment...
