• Subjects with RAS-mutant and NF1-mutant (no concurrent BRAFV600 mutations) melanoma that have not taken prior immune checkpoint inhibitors will be allowed if they are not eligible to receive prior immune checkpoint inhibitors due to requirement for immunosuppression
• 5. Measurable or non-measurable (but evaluable) disease according to RECIST v1.1 for dose escalating cohorts; measurable disease as per RECIST v1.1 required for expansion cohort
• 6. Life expectancy ≥ 12 weeks
• 7. Recovered from all reversible acute toxic effects of last anti-cancer treatment (other than alopecia) to ≤Grade 1 or baseline. Patients with baseline neuropathy that is ≤ grade 2 are eligible for enrollment.
• 8. Demonstrate adequate organ function as defined in the table below; all screening labs to be obtained within 28 days prior to day -6 of ulixertinib
• Hemoglobin (Hgb) ≥ 9 g/dL Absolute Neutrophil Count (ANC) ≥ 1,500 /mm3 Platelets ≥ 100,000/mm3 Creatinine ≤1.5 x upper limit of normal (ULN) or Calculated creatinine clearance ≥ 60 mL/min using the Cockcroft-Gault formula Bilirubin ≤ 1.5 x ULN Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) ≤ 2.5 x ULN; if tumor involvement of the liver ≤ 5 x ULN
• 9. Adequate cardiac function; left ventricular ejection fraction (LVEF) \>50% as assessed by ultrasound/echocardiography (ECHO) and corrected QT interval (QTc)
• 10. Females of childbearing potential must have a negative serum pregnancy test within 3 days prior to day -6 of ulixertinib. NOTE: Females are considered of childbearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are naturally postmenopausal for at least 12 consecutive months
• 11. Females of childbearing potential and males must be willing to abstain from heterosexual activity\* or use effective methods of contraception from the time of informed consent until 120 days after treatment discontinuation. Acceptable contraception methods can be comprised of an intrauterine device (IUD), vasectomy of a female subject's male partner, contraceptive rod implanted into the skin, OR use of two of the following: diaphragm with spermicide (cannot be used in conjunction with cervical cap/spermicide), cervical cap with spermicide (nulliparous women only), contraceptive sponge (nulliparous women only), male condom or female condom (cannot be used together), hormonal contraceptive.\] \*Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
• 12. Subject is willing and able to comply with study procedures based on the judgment of the investigator or protocol designee.
• 13. Willing to provide archival tissue (if available) and consent to mandatory pretreatment and on-treatment biopsy as deemed safe by the treating physician (expansion cohort only) for research purposes only.

Exclusion criteria

• 1. Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on the study)
• 2. Treatment with any cancer-directed therapy (chemotherapy, hormonal therapy, biologic, radiation or immunotherapy, etc.) or investigational drug within 28 days or 5 half-lives (whichever is shorter) prior to day -6 of ulixertinib
• 3. A history or current evidence/risk of retinal vein occlusion (RVO) or central serous retinopathy (CSR).
• 4. Major surgery within 28 days prior to day -6 of ulixertinib
• 5. Not willing to avoid grapefruit, grapefruit juices, grapefruit hybrids, oranges, pummelos, and exotic citrus fruits from 7 days prior to day -6 of ulixertinib and during the entire study due to potential CYP3A4 interaction with the study medications.
• 6. Intake of any herbal preparations or medications (including, but not limited to, Saint John's Wort and ginkgo biloba) and dietary supplements within 7 days prior to day -6 of ulixertinib due to potential CYP3A4 interaction with the study medications
• 7. Unable or unwilling to discontinue use of any drug known to be a strong inhibitor of CYP3A4, CYP1A2 or CYP2D6 or strong inducer of CYP3A4 (prohibited inducers and inhibitors must be discontinued within 2 weeks prior to day -6 of ulixertinib; see section 10.3 Appendix C)
• 8. Unable or unwilling to discontinue use of any drug known to be a sensitive CYP3A4 substrate with a narrow therapeutic index as defined in the protocol.
• 9. Central nervous system metastases are allowed only for patients RAS-mutated and NF1-mutant melanoma cohorts (1) no leptomeningeal disease is present, (2) Intracranial disease is controlled by prior therapies, as evidenced by brain imaging 2 weeks post treatment indicating no new intracranial disease, (3) stable or decreasing dose of steroids is provided patient on ≤ 20mg of prednisone or it's equivalent daily.
• 10. Any important medical illness or abnormal laboratory finding that would increase the risk of participating in the study (based on the investigator's judgment)
