Age: 18 and older, up to 100. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 1. Read, understood, and provided written informed consent and, if applicable, Health Insurance Portability and Accountability Act (HIPAA) authorization after the nature of the study has been fully explained and must be willing to comply with all study requirements and procedures.
• Male or female patients who are 18 years of age or older. 3. Patients with a diagnosis of histologically confirmed advanced (defined as unresectable stage III or IV) melanoma with the NRAS Q61 mutation or BRAF/NRAS WT for which there is no remaining standard therapy with curative potential or patients are ineligible or unable to tolerate therapy with curative potential.
• Any standard of care mutation testing is acceptable to document mutation status.
• Patients must have archival tissue and at least one disease site amenable to biopsy:
• For phase Ib, all patients will undergo fresh tumor biopsy
• For phase II, five patients with NRAS mutation and five patients with BRAF/NRAS WT melanoma will undergo fresh tumor biopsy 5.Measurable (target) disease by Response Evaluation Criteria In Solid Tumors (RECIST 1.1) criteria. Target lesions selected for tumor measurements should be those where additional (eg palliative) treatments are not indicated or anticipated.
• Measurable disease per RECIST 1.1 requirements: defined as longest diameter to be recorded for non-nodal lesions > 10mm and short axis for nodal lesions >15 mm using conventional techniques 6.All residual toxicity related to prior radiotherapy or anticancer therapies (excluding alopecia, grade 2 fatigue, vitiligo or endocrinopathies on stable replacement therapy) must resolve to grade 1 severity or less (or returned to baseline) prior to receipt of study treatment.
• Adequate electrolytes, liver, renal, and hematology function as defined below:
• a.Hemoglobin ≥ 9 g/dL b.Absolute neutrophil count ≥ 1500/mm3 c.Platelet count ≥ 100,000/mm3 d.Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × upper limit of normal (ULN) (≤ 5 × ULN for cases involving liver metastasis) e.Bilirubin ≤ 1.5 × ULN (≤ 5 × ULN for cases of documented or suspected Gilbert's disease) f.Serum creatinine ≤ 1.5 g/dL or calculated creatinine clearance (CrCl) ≥60 mL/min for patients with serum creatinine > 1.5 x ULN g.Serum magnesium, calcium and potassium within normal limits 8.Life expectancy ≥ 12 weeks 9.ECOG performance status (PS) < 1 10.Willing and able to comply with scheduled visits, treatment plan, and laboratory tests.
• Screening EKG without clinically significant abnormalities. 12.Corrected (Fridericia's) QTcF must be < 480 milliseconds. 13.Allowance of prior therapy regimens:
• No limit on prior number of regimens
• Must have completed prior cytotoxic chemotherapy a minimum of 4 weeks prior to starting study treatment (except for bis-chlorethynitrosurea (BCNU)), which must have been completed a minimum of 6 weeks prior to starting therapy.
• Prior localized radiation therapy must have been completed a minimum of 2 weeks prior to starting therapy and the patient must have baseline imaging with a full body PET-CT or CT scans of the chest, abdomen, and pelvis and within 4 weeks prior to study enrollment.
• For CNS metastases, disease must be treated and demonstrate stability with Brain MRI a minimum of 2 weeks prior to starting therapy.
• Both male and female patients enrolled in this trial must agree to use highly effective contraception during the course of the trial and for at least for 6 months after the final dose of CDX-3379 (an effective form of contraception is an oral contraceptive or a double barrier method), or greater, as in accordance with the label requirements for trametinib. Patients and/or partners who are surgically sterile or postmenopausal are exempt from this requirement.
• Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 3 months after stopping study drug. Highly effective contraception methods include:
• Total abstinence or
• Male or female sterilization or
• Combination of any two of the following (a+b or a+c or b+c):
• Use of oral, injected or implanted hormonal methods of contraception; hormonal contraceptives are not acceptable as a sole method of contraception.
• Placement of an intrauterine device (IUD) or intrauterine system (IUS)
• Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository 15. Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.

You may not qualify if…

• Received CDX-3379 or other anti-ErbB3 targeted agents previously.
• Received trametinib or other MEK inhibitor agents previously.
• Any concurrent chemotherapy, radiotherapy, immunotherapy, biologic or hormonal therapy for cancer treatment. Concurrent use of hormones for non-cancer related conditions (e.g., insulin for diabetes and hormone replacement therapy) is acceptable.

• Active central nervous system (CNS) metastases are excluded. Known brain metastases must have been previously treated and asymptomatic for 2 weeks and not progressive in size or number for 4 weeks prior to enrollment, documented via scans. Continued use of anticonvulsants (in the absence of any suspicion of progressive brain metastases) is acceptable. Patients must currently be on a stable, lowest possible dose of steroids.
• Radiation therapy within 14 days prior to the first scheduled dose in this study, including, in addition (if necessary), the timeframe for resolution of any actual or anticipated toxicities from such radiation.
• Known HIV, hepatitis B or hepatitis C infection, or active infection requiring systemic intravenous therapy
• Use of any monoclonal based therapies within 4 weeks (excluding cetuximab which does not require a wash-out), and all other immunotherapy (tumor vaccine, cytokine, or growth factor given to control the cancer) within 2 weeks, prior to the first dose of study treatment.
• Chemotherapy within 4 weeks (except for bis-chlorethynitrosurea (BCNU), which must have been completed a minimum of 6 weeks) prior to starting therapy.
• Major surgery within 4 weeks prior to the first dose of study treatment. Surgery requiring local/epidural anesthesia must be completed at least 72 hours before study drug administration and patients should be recovered.

• A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval >450 ms); additional risk factors for torsades de pointes (TdP) (e.g., a history of heart failure, family history of Long QT Syndrome, or active hypokalemia or uncorrectable electrolyte abnormality); significant cardiovascular disease including unstable angina pectoris, uncontrolled hypertension or arrhythmia, congestive heart failure (New York Heart Association Class III or IV) related to primary cardiac disease, uncontrolled ischemic or severe valvular heart disease; or any of the following within 6 months prior to the first dose of study treatment: myocardial infarction, severe/unstable angina, coronary artery bypass graft, congestive heart failure, cerebrovascular accident, transient ischemic attack.
• Requirement for chronic immunosuppressive medication including systemic corticosteroids above the physiologic dose (defined as 20 mg/day prednisone or the equivalent).
• Any other acute or chronic medical or psychiatric condition or laboratory abnormality that could increase the risk associated with trial participation or trial drug administration or could interfere with the interpretation of trial results and, in the judgment of the investigator, would make the patient inappropriate for entry into the trial.
• Known alcohol or drug abuse.
• Sexually active males must use a condom during intercourse while taking the drug and for 3 months after stopping study drug and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
