Molecularly Targeted Therapy in Treating Patients With BRAF Wild-type Melanoma That is Metastatic

This phase II trial studies how well molecularly targeted therapy works in treating patients with melanoma that has spread to other parts of the body. Patients must have received or do not qualify for prior immunotherapy. Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific types of cancer cells with less harm to normal cells. Molecularly targeted therapy works by treating patients with substances that kill cancer cells by targeting key molecules involved in cancer cell growth.

PRIMARY OBJECTIVES:

I. To determine the difference in best overall response rate (BORR) between patients treated with MEK162 following personalized molecularly guided assignment vs. a historical BORR of 7% in this patient population.

SECONDARY OBJECTIVES:

I. To evaluate the safety of performing individualized drug therapy (including novel agents and commercially-available agents) in the context of a personalized medicine clinical trial.

II. To define the difference in progression free survival (PFS) between patients treated with MEK162 following personalized molecularly guided assignment vs. a historical PFS rate of 2 months in this patient population.

III. To continually assess data in real time so as to iteratively refine and standardize a set of statistical and informatics methodologies for matching treatments to the patient's tumor, based on the molecular profile.

OUTLINE:

Patients undergo collection of tissue and blood samples for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) analysis via sequencing. Based on the results of the DNA and RNA analysis, patients receive molecularly targeted therapy. Treatment continues in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days.

Eligibility Criteria:
Inclusion Criteria:

* Patient with metastatic or locally advanced and unresectable BRAF wild-type melanoma who have either progressed following previous treatment of immunotherapy, or are not eligible for immunotherapy; pts. are defined as "BRAF wild-type" if they test negative for V600 mutations based on a Clinical Laboratory Improvement Amendments (CLIA) certified assay
* Patients must have tumor accessible by interventional radiology or surgical intervention and suitable for biopsy (BX) with 5-6 passes of a 16 or 18 gauge needle for core BX (defined as at least 1 cm\^3 tumor/50 mg accessible for BX), and must agree to undergo up to two surgical resections/biopsies to collect tumor for research purposes; the first of these biopsies will occur at the beginning of the study, prior to genetic analysis and Rx; the second BX will be performed at the time of DZ progression/end of study should funding be available
* Patients must have measurable DZ (per Response Evaluation Criteria in Solid Tumors \[RECIST\] version 1.1 \[v1.1\] criteria), defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as \>= 20 mm with conventional techniques or as \>= 10 mm with spiral computed tomography (CT) scan, magnetic resonance imaging (MRI), or a subcutaneous or superficial lesion that can be measured with calipers by clinical exam; for lymph nodes, the short axis must be \>= 15 mm
* Previous therapies: prior radiation therapies, immunotherapies, and investigational therapies are allowed as follows.

  * Radiation: prior radiation therapy (RT) is allowed with the following conditions:

    * Patients who have received minimal RT (=\< 5% of their total marrow volume) must have completed it \>= 2 weeks prior to the initiation of study Rx
    * Patients who have received RT that constituted \> 5% but \< 50% of their total marrow volume must have completed it \>= 4 weeks prior to the initiation of study treatment
    * Patients who have received prior radiation to 50% or more of their total marrow volume will be excluded
    * Patients may be biopsied while undergoing RT as long as BX site is not in the radiation portal; however, they still have to wait the required amount of time from radiation to treatment even though the tumor board may have already occurred and a treatment plan assigned
  * Other therapies: prior investigational or targeted therapies and immunotherapies may be allowed following discussion with the PI (PI); if the PI deems the prior treatment acceptable, patients must not have received these therapies for 28 days or five half-lives of the drug (whichever is lesser) prior to the initiation of study treatment and must have full recovery from any acute effects of these therapies; prior therapy with mitogen-activated protein kinase (MEK) inhibitors will not be allowed
* Patients with chronic grade 2 toxicity may be eligible at the discretion of the PI if the condition has been stable, and not worsening, for at least 30 days; pts. with ongoing alopecia of any grade will be eligible

* Patient must have an Eastern Cooperative Oncology Group (ECOG) performance status =\< 2
* Hemoglobin \>= 9 g/dL
* Leukocytes \>= 3,000/microliter (mcL)
* Absolute neutrophil count (ANC) \>= 1,500/mcL
* Platelets (PLT) \>= 100,000/mcL
* Aspartate aminotransferase (AST) =\< 2.5 x upper limit of normal (ULN); if liver metastases are present, =\< 5 x ULN

* Patient agrees to having a blood sample (a minimum of 10 mL, with 20 mL preferred) drawn and analyzed to compare their normal genetic profile to that of their tumor sample
* Patient must be able to tolerate oral medication
* Women of child-bearing potential and men must agree to use 2 forms of adequate contraception (hormonal or barrier method of birth control; abstinence) for the duration of study participation, and for four months following completion of study therapy; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately; women who become pregnant must immediately discontinue Rx with any study therapy; male pts. should avoid impregnating a female partner; male pts., even if surgically sterilized, (i.e. post-vasectomy) must agree to one of the following: practice effective barrier contraception during the entire study Rx period and through 4 months after the last dose of study drug, or completely abstain from sexual intercourse
