Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Signed informed consent
• Histologically confirmed metastatic melanoma (Stage IV), carrying BRAF V600-mutation
• Melanoma must be documented to contain a BRAFV600 mutation by a CLIA approved laboratory
• At least one measurable intracranial target lesion for which all of the following criteria are met:
• previously untreated or progressive according to RECIST 1.1 (equal to or greater than 20% increase in longest diameter on baseline scan) after previous local therapy (SRS and/or craniotomy)
• immediate local therapy clinically not indicated or patient is not a suitable candidate to receive immediate local therapy (SRS and/or craniotomy)
• largest diameter of ≥ 0.5cm but ≤ 4 cm as determined by contrast-enhanced MRI
• Prior therapies for extracranial metastatic melanoma including chemo-, cytokine-, immuno-, biological- and vaccine-therapy will be allowed but prior BRAF or MEK not allowed
• ECOG PS 0-2
• Life expectancy >12 weeks
• Age 18 years or older
• Adequate bone marrow function as indicated by the following:
• ANC > 1500/µL
• Platelets ≥ 100,000/µL
• Hemoglobin > 9 g/dL
• Adequate renal function, as indicated by creatinine =/< 1.5 x the upper limit of normal (ULN)
• Adequate liver function, as indicated by bilirubin =/< 1.5 x ULN
• AST or ALT < 3 x ULN (patients with documented liver metastases: AST and/or ALT =/< 5 x ULN)
• Able to swallow pills
• Negative serum pregnancy test within 7 days prior to commencement of dosing in premenopausal women. Women of non-childbearing potential may be included without serum pregnancy test if they are either surgically sterile or have been postmenopausal for ≥ 1 year
• Fertile men and women must use an effective method of contraception during treatment and for at least 6 months after completion of treatment as directed by their physician. Effective methods of contraception are defined as those which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly (for example implants, injectables, combined oral contraception or intra-uterine devices). At the discretion of the Investigator, acceptable methods of contraception may include total abstinence in cases where the lifestyle of the patient ensures compliance. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)

You may not qualify if…

• Active infection
• Prior therapy with BRAFi and/or MEKi
• Leptomeningeal disease
• Symptomatic brain metastases requiring immediate local interventions such as craniotomy or SRS
• Increasing corticosteroid dose in 7 days prior to administration of first dose of study drug. Symptomatic patients that have stable or decreasing corticosteroid use in the past 7 days will be allowed
• Current use of therapeutic warfarin
• Unresolved toxicity of National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0 (NCI v4.0) [NCI, 2009] Grade 2 or higher from previous anti-cancer therapy, except alopecia
• Conditions that will interfere significantly with the absorption of drugs
• Inability to undergo MRI secondary to metal, claustrophobia, Gadolinium Contrast allergy
• Pregnant, lactating, or breast feeding women
• Prior radiation therapy within the last 14 days
• Concomitant malignancies or previous malignancies within the last 5 years, with the exception of adequately treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix
• Unwillingness or inability to comply with study and follow-up procedures
• The following foods/supplements are prohibited at least 7 days prior to initiation of and during study treatment:
• St. John's wort or hyperforin
• Grapefruit juice
• History of or evidence of retinal pathology on ophthalmologic examination that is considered a risk factor for neurosensory retinal detachment, Retinal Vein Occlusion (RVO), or neovascular macular degeneration
• Uncontrolled glaucoma with intra-ocular pressures > 21mmHg
• Serum cholesterol ≥ Grade 2
• Hypertriglyceridemia ≥ Grade 2
• Hyperglycemia (fasting) ≥ Grade 2
• History of clinically significant cardiac dysfunction, including the following:
• Current unstable angina
• Current symptomatic congestive heart failure of NYHA class 2 or higher
• History of congenital long QT syndrome or mean QTcF > 450 msec at baseline or uncorrectable electrolyte abnormalities
