War against NRAS-Mutant Melanoma Using Targeted Therapies Remains Challenging.

In the search for targeting MAPK plus other pathways in NRAS-mutant melanoma, a phase Ib/II trial tested binimetinib plus ribociclib in metastatic melanoma. The response rate in the phase II trial was 19.5%, and the median progression-free survival was 3.7 months. See related article by Schuler et al., p. 3002.
