Known or suspected hypersensitivity or allergy to any of the study drugs or excipients contained in the study drug formulations. In addition, allergy to other medications or other type of hypersensitivity may warrant exclusion at the investigator's discretion.
Female subjects who are pregnant or breastfeeding.
History or current evidence of any other medical or psychiatric condition or addictive disorder, or laboratory abnormality that, in the opinion of the investigator, may increase the risks associated with study participation, or require treatments that may interfere with the conduct of the study or the interpretation of study results.

Prior radiotherapy to the orbital region at any time before the start of treatment
Prior radiotherapy to tumor lesion(s) that will be chosen as target lesions within 4 weeks before the start of treatment, unless the lesion(s) exhibited objective progression between the prior radiotherapy and the screening CT or MRI scan.
° Prior palliative radiotherapy to non-target lesions may be allowed at the investigator's discretion at any time before the start of treatment.
Prior therapy with a live vaccine(s) within 4 weeks before the start of treatment or likely to require live vaccine(s) at any time during the treatment.
* Injectable flu vaccine (inactivated or recombinant) may be permitted at the investigator's discretion at any time before or during the treatment.
* Covid-19 vaccination (any type) is permitted either before or during this protocol and does not preclude trial enrollment, at the discretion of the investigator.
Prior antibiotic therapy for active infection ≤2 weeks before the start of treatment
Prior therapy with platelet or blood transfusion for the treatment of thrombocytopenia within 2 weeks before the start of treatment.
* Blood transfusion for the treatment of anemia within 2 weeks before the start of treatment may be acceptable at the investigator's discretion.

You may not be if
Class 1 or class 2 MEK1 or MEK2 mutations, as described below, documented by a CLIA-certified NGS assay at any time before the start of treatment. Class 3 MEK1 or MEK2 mutations as described in that paper are excluded. A complete list of the mutations allowed based on that paper can be found below, however, rare mutations not listed in this table may be permitted at the discretion of the principal investigator of the study. Note: archival tissue, if available and collected within 6 months of enrollment, may be used for this testing in lieu of fresh tissue.
The permitted mutations shown above are for MEK1. MEK1 and MEK2 are closely related, are structurally similar, share 79% amino acid identity, and they share equal ability to phosphylate their ERK substrates30. While the experiments performed above classify individual MEK1 mutations only, the class 3 mutations in MEK1 all share in-frame deletions that remove a potent negative regulatory element of MEK1. These are easily distinguishable from other mutations in MEK1. Therefore, the identification of exclusionary class 3 MEK2 alterations will be straightforward as well, with paralogous mutant residues in MEK1 and MEK2 defined in the manuscript above. A table showing the permitted enrolling paralogous class 1 and class 2 residues are shown in the table below, again with the caveat that rare mutations in MEK2 not listed in the table below may be eligible at the discretion of the principal investigator.
Patient (or Legally Authorized Representative \[LAR\]) must sign written informed consent form before any study-specific procedure is performed
ECOG performance score of 0 or 1
Life expectancy of ≥3 months
At least one tumor lesion measurable by RECIST 1.1. A lesion in a previously irradiated area may be considered as measurable disease if there is objective evidence of progression of the lesion by RECIST 1.1 (Eisenhauer EA et al, 2009) between the prior radiotherapy and the screening CT or MRI scan.
Adequate bone marrow function at screening, as determined by:
Adequate kidney function at screening, as determined by ° Estimated glomerular filtration rate (eGFR) \>60 mL/min/1.73 m2 calculated by the CKD-EPI equation (CTCAE Grade ≤ 1).
Adequate hepatic function at screening, as determined by:
° Total bilirubin ≤1.5 x ULN if baseline was normal or ≤1.5 x baseline if baseline was abnormal (CTCAE Grade ≤1). Patients with previously documented Gilbert's Syndrome may have total bilirubin ≤3 x ULN.
* AST ≤3.0 x ULN if baseline was normal or ≤3.0 x baseline if baseline was abnormal (CTCAE Grade ≤1).
* ALT ≤3.0 x ULN if baseline was normal or ≤3.0 x baseline if baseline was abnormal (CTCAE Grade ≤1).
Adequate coagulation function at screening, as determined by:
° INR ≤1.5 x ULN if not on anticoagulant therapy or \>1.5 x baseline if on anticoagulant therapy (CTCAE Grade ≤1). If the patient receives anticoagulant therapy, the dose must be stable for at least 2 weeks before the start of treatment.
° PTT ≤1.5 x ULN
Adequate cardiac function at screening, as determined by:
* Systolic blood pressure \<150 mmHg and diastolic blood pressure \<90 mmHg (CTCAE Grade ≤1). Note: Anti-hypertensive medications are permitted, and if a patient does not meet these eligibility criteria at time of screening, treatment with additional anti-hypertensive agents is permissible at the discretion of the investigator, and blood pressure can be rechecked at a subsequent visit. Measured blood pressures that fall out of this range after screening do not render patients ineligible, however every effort should be made to medically manage these elevated blood pressures at the investigator's discretion.
* LVEF ≥50% by MUGA or ECHO.
* No clinically significant ECG waveform abnormalities at the investigator's discretion
* QTcF ≤470 ms
Adequate serum lipid profile at screening, as determined by
° Serum cholesterol \<300 mg/dL
° Serum triglycerides \<300 mg/dL
Adequate glycemic control at screening, as determined by
° Fasting blood glucose \<140 mg/dL or
° Random blood glucose \<250 mg/dL Note: Anti-hyperglycemic medications are permitted if a patient does not meet these eligibility criteria at time of screening. Blood glucose measurements that fall out of this range do not render patients ineligible, and appropriate glycemic control at subsequent visits is at the discretion of the investigator.
Blood calcium and phosphate levels within normal levels per institutional lab standard at screening (calcium level may be corrected for albumin at the investigator's discretion)
Adequate ophthalmological exam in both eyes at screening, as determined by ° Intraocular pressure ≤21 mmHg
° No clinically significant abnormalities on the ocular tomography (OCT), including no evidence of ocular abnormality that would be considered a significant risk factor for central serous retinopathy, retinal vein occlusion (RVO), or neovascular macular degeneration (mild and controlled / stable age-related macular degeneration may be acceptable at the investigator's discretion).
