• Platelets >= 100,000/mcL
• Hemoglobin >= 9.0 g/dL (not requiring transfusions within the past 2 weeks)
• Total bilirubin =< 1.5 x institutional upper limit of normal; Note: patients with hyperbilirubinemia clinically consistent with an inherited disorder of bilirubin metabolism (e.g., Gilbert syndrome) will be eligible at the discretion of the treating physician and/or the principal investigator
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 1.5 x institutional upper limit of normal for patients with no concurrent liver metastases, OR =< 2.5 x institutional upper limit of normal for patients with concurrent liver metastases
• Creatinine =< 1.5 mg/dL OR calculated creatinine clearance (Cockcroft-Gault formula) >= 50 mL/min OR 24-hour urine creatinine clearance >= 50 mL/min
• Left ventricular ejection fraction >= institutional lower limit of normal (LLN) by echocardiogram (ECHO) or multigated acquisition scan (MUGA)
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; women of child-bearing potential must have a negative blood pregnancy test within 14 days prior to start of protocol treatment; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of trametinib administration
• Ability to understand and the willingness to sign a written informed consent document
• Patients must agree to provide all imaging studies for central radiology review; this central radiology review may be performed retrospectively and will not be utilized for decision making for patients on study
• ELIGIBILITY CRITERIA FOR CROSSOVER REGISTRATION
• Previously treated with trametinib on Arm A and experienced objective disease progression by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
• Not removed from trametinib treatment due to the development of unacceptable toxicity that is not manageable with dose reduction
• No other drug treatment for malignant melanoma administered after completing study treatment with trametinib

• Meet all eligibility criteria with the exception of:

  • Prior therapy with trametinib will be permitted
  • All laboratory parameters must be met as outlined except for ALT and total bilirubin, which must meet criteria for continued therapy
  • Patients who are eligible for cross-over will not need to undergo another ophthalmologic examination

Exclusion Criteria:

• History of another malignancy except for those who have been disease-free for 3 years, or patients with a history of completely resected non-melanoma skin cancer and/or patients with indolent secondary malignancies not requiring active therapy, are eligible; consult the study MSK Principal Investigator or the Cancer Therapy Evaluation Program (CTEP) Medical Monitor if unsure whether second malignancies meet the requirements specified above
• History of interstitial lung disease or pneumonitis
• Any major surgery or extensive radiotherapy within 21 days prior to randomization and crossover
• Use of other investigational drugs within 28 days (or five half-lives, whichever is shorter; with a minimum of 14 days from the last dose) preceding the first dose of trametinib alone or with GSK2141795 and during the study
• Symptomatic or untreated leptomeningeal or brain metastases or spinal cord compression; treated brain metastases must have been stable for at least 1 month
• Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to trametinib, GSK2141795, or excipients or to dimethyl sulfoxide (DMSO)
• Current use of a prohibited medication
• History or current evidence/risk of retinal vein occlusion (RVO) or retinal pigment epithelial detachment (RPED) in the eye unaffected by uveal melanoma
• Patients with abnormal fasting glucose values (values > upper limit of normal [ULN] or < LLN) at screening will be excluded; in addition, patients with type 1 diabetes will also be excluded; however, patients with type 2 diabetes will be allowed if diagnosed >= 6 months prior to enrollment, and if presenting with a normal fasting glucose value and a regular hemoglobin A1C (HbA1C) =< 8% at screening

• History or evidence of cardiovascular risk including any of the following:

  • Left ventricular ejection fraction (LVEF) < LLN
  • A QT interval corrected for heart rate using the Bazett's formula QTcB >= 480 msec
  • History or evidence of current clinically significant uncontrolled arrhythmias (exception: patients with controlled atrial fibrillation for > 30 days prior to randomization are eligible)
