Patient description: A 22-year-old Caucasian man came to the Clinic with a history of tremors since a year ago. The tremor was first in his right hand while holding something. Later the tremor became continuous and extended to both hands and legs and even at rest. The Kayser-Fleischer' ring was detected in the ophthalmologic exam. The physical exam revealed jaundice, hepatosplenomegaly and hypotonia of the upper limbs. He had a constant smile on his face, however, he has aggressive behavior according to his parents' explanation. His laboratory study was significant for a low serum caeruloplasmin (0.05 g/l), and a raised 24 hour urine copper excretion (120 μg/24 h). Wilson disease was confirmed by high liver copper concentration (305 μg/g dry weight of liver).

Clinical trial eligibility criteria: eligible ages (years): 18.0-999.0,  Melanoma Willing and able to give written informed consent. 2. ECOG performance status ≤ 1 3. Histologic diagnosis of unresectable stage IIIC or stage IV melanoma that is BRAF V600 mutation positive 4. Stable, treated brain metastases are allowed. Stable brain metastases are defined as stable on MRI 4 weeks after the completion of radiation, and currently asymptomatic no longer requiring corticosteroids for 2 weeks prior to the initiation of study drug. 5. Cutaneous tumor deposits that, in the opinion of the investigator are amenable to sequential biopsies for correlative analyses. In addition to these, all patients must have measurable disease (i.e., present with at least one measurable lesion per version 1.1). 6. Able to swallow and retain oral medication and must not have any clinically significant gastrointestinal abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels. 7. Required values for initial laboratory tests WBC ≥ 2000/uL ANC ≥ 1000/uL Platelets ≥ 75 x 103/uL Hemoglobin ≥ 9 g/dL (≥ 80 g/L; may be transfused) Creatinine ≤ 2.0 x ULN AST/ALT ≤ 2.5 x ULN for patients without liver metastasis, ≤ 5 times for liver metastases Bilirubin ≤ 2.0 x ULN, (except patients with Gilbert's Syndrome, who must have a total bilirubin less than 3.0 mg/dL) 8. Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 26 weeks after the last dose of investigational product, in such a manner that the risk of pregnancy is minimized. WOCBP any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not post-menopausal. Post-menopause is defined as Amenorrhea ≥ 12 consecutive months without another cause, or For women with irregular menstrual periods and taking hormone replacement therapy (HRT), a documented serum follicle stimulating hormone (FSH) level ≥ 35 mIU/mL. Women who are using oral contraceptives, other hormonal contraceptives (vaginal products, skin patches, or implanted or injectable products), or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy, or are practicing abstinence or where their partner is sterile (eg, vasectomy) should be considered to be of childbearing potential. WOCBP must have a negative serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours. Men of fathering potential must be using an adequate method of contraception to avoid conception throughout the study [and for up to 26 weeks after the last dose of investigational product] in such a manner that the risk of pregnancy is minimized  Prior treatment with a BRAF or MEK inhibitor for metastatic melanoma (treatment in the adjuvant setting is allowed) 2. Any other malignancy form which the patient has been disease-free for less than 2 years, with the exception of adequately treated and cured basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix, or DCIS. Patients with prior malignancies that are not considered to be an active problem may be enrolled at the discretion of the investigator, regardless of time frame. 3. Women of childbearing potential (WOCBP), defined above in Section 4.1, who: 1. are unwilling or unable to use an acceptable method of contraception to avoid pregnancy for their entire study period and for at least 26 weeks after cessation of study drug, or 2. have a positive pregnancy test at baseline, or 3. are pregnant or breastfeeding. 4. Anti-cancer therapy within 28 days prior to starting on therapy 5. Any serious or unstable pre-existing medical conditions psychiatric disorders, or other conditions that could interfere with the subject's safety, obtaining informed consent, or compliance with study procedures. 6. Known history of Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), or Hepatitis C Virus (HCV) infection (with the exception of chronic or cleared HBV and HCV infection which will be allowed). 7. A history or evidence of cardiovascular risk including any of the following: 1. A QTc interval ≥ 500 ms at screening 2. A history or evidence of current clinically significant uncontrolled arrhythmias; Exception: Subjects with atrial fibrillation controlled for > 30 days prior to randomization are eligible. 3. A history (within 6 months prior to randomization) of acute coronary syndromes (including myocardial infarction or unstable angina), coronary angioplasty 4. A history or evidence of current ≥Class II congestive heart failure as defined by the New York Heart Association (NYHA) guidelines 5. Treatment refractory hypertension defined as a blood pressure of systolic> 150 mmHg and/or diastolic > 100 mm Hg which cannot be controlled by antihypertensive therapy; 6. Patients with intra-cardiac defibrillators or permanent pacemakers; 8. A history or current evidence/risk of retinal vein occlusion (RVO) or central serous retinopathy (CSR) including: a. Presence of predisposing factors to RVO or CSR (e.g., uncontrolled glaucoma or ocular hypertension, uncontrolled hypertension, uncontrolled diabetes mellitus, or a history of hyperviscosity or hypercoagulability syndromes) 9. Females who are nursing 10. A known diagnosis of Wilson's disease. 11. Patients with clinical symptoms consistent with active gastritis. 12. Patients with a condition that, in the opinion of the investigator, would interfere with the absorption of oral medication will be excluded from the study. 13. Patients requiring iron supplementation will be excluded
