Note: Patients with previously treated brain metastases may participate provided they are stable (e.g., without evidence of progression by radiographic imaging for at least 28 days before the first dose of study treatment and neurologic symptoms have returned to baseline), and have no evidence of new or enlarging brain metastases or central nervous system (CNS) edema, and does not require steroids at least 7 days before the first dose of study treatment Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements  Impaired cardiovascular function or clinically significant cardiac diseases including, but not limited to, any of the following:  History of acute coronary syndromes (including myocardial infarction, unstable angina, coronary artery bypass grafting, coronary angioplasty or stenting) < 6 months prior to screening Congestive heart failure requiring treatment (New York Heart Association grade >= 2) Left ventricular ejection fraction (LVEF) < 50% as determined by multigated acquisition scan (MUGA) or echocardiography (ECHO) Uncontrolled hypertension defined as persistent systolic blood pressure >= 150 mmHg or diastolic blood pressure >= 100 mmHg despite current therapy History or presence of clinically significant cardiac arrhythmias (including resting bradycardia, uncontrolled atrial fibrillation or uncontrolled paroxysmal supraventricular tachycardia) Baseline corrected QT (QTc) interval >= 480 ms Impairment of gastrointestinal function or disease which may significantly alter the absorption of binimetinib or palbociclib (e.g., active ulcerative disease, uncontrolled vomiting or diarrhea, malabsorption syndrome, small bowel resection with decreased intestinal absorption), or recent (=< 3 months) history of a partial or complete bowel obstruction, or other conditions that will interfere significantly with the absorption of oral drugs Patients who have neuromuscular disorders that are associated with elevated creatine kinase (CPK) (e.g. inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis, spinal muscular atrophy) History or current evidence of retinal vein occlusion (RVO) or current risk factors to RVO (e.g. uncontrolled glaucoma or ocular hypertension, history of hyperviscosity or hypercoagulability syndromes) Current use of a prohibited medication (including herbal medications, supplements, or foods) or use of a prohibited medication =< 1 week prior to the start of study treatment History of or cerebrovascular events =< 12 weeks prior to the first dose of study treatment History of pulmonary embolism (PE) with hemodynamic instability =< 12 weeks prior to first dose of study treatment. Note: Patients with PE that does not result in hemodynamic instability are allowed to enroll as long as they are on a stable dose of therapeutic anticoagulants for at least 4 weeks. Also, patients with deep vein thrombosis on stable dose of therapeutic anticoagulants for at least 4 weeks are allowed to participate in the study Concurrent or previous other malignancy that requires active anticancer therapy Known history of positive test for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS)  Evidence of hepatitis B virus (HBV) or hepatitis C virus (HCV) infection  Note: Patients with laboratory evidence of cleared HBV or HCV infection may be enrolled Note: Patients with no prior history of HBV infection who have been vaccinated against HBV and who have a positive antibody against hepatitis B surface antigen as the only evidence of prior exposure may be enrolled Known history of acute or chronic pancreatitis =< 6 months prior to enrollment History of chronic inflammatory bowel disease or Crohn's disease requiring medical intervention (immunomodulatory or immunosuppressive medications or surgery) =< 12 months prior to enrollment Known hypersensitivity to the components of study drugs or its analogs Pregnant or nursing female participants Unwilling or unable to follow protocol requirements Other severe, acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study treatment administration or that may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient an inappropriate candidate for the study  The following special populations will not be included in the study:  Cognitively impaired adults/adults with impaired decision-making capacity Individuals who are not yet adults (infants, children, teenagers) Pregnant women Prisoners
