This phase I study is designed to establish the safety, maximally tolerated dose (MTD) and recommended phase II dose (RP2D) of the ERK inhibitor ulixertinib (BVD-523) when combined with the CDK4/6 inhibitor palbociclib.~Up to a maximum of 30 adult patients will be enrolled in the 5 possible dose escalation cohorts. These patients will have histologically confirmed advanced solid tumor disease refractory to standard of care therapy, or for which there is no accepted standard of care.~An expansion cohort enrollment will start After RP2D of ulixertinib combined with palbociclib is defined. Then 15 patients with metastatic pancreatic cancer and 15 patients with RAS-mutant melanoma will be enrolled.~Note:Pancreatic cancer expansion cohort and all solid tumor cohorts are closed to enrollment.
