Brief Summary:
This phase II trial studies how well selumetinib works in treating patients with neurofibromatosis type 1 and plexiform neurofibromas (tumors which arise from the nerves) that cannot be removed by surgery (inoperable). Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Primary Outcome Measures :
  1. Objective response rate (plexiform neurofibroma [PN] volume decrease >= 20% compared to baseline) [ Time Frame: Up to 30 days ]

Secondary Outcome Measures :
  1. Change in levels of pERK [ Time Frame: Baseline to up to 30 days ]
    The changes from baseline will be determined and tested for statistical significance using a Wilcoxon signed rank test. The correlation of levels and changes of levels of P-ERK in PNs, dermal tumors, and peripheral blood mononuclear cells (PBMCs) will be determined using Spearman rank correlation. The inhibition of P-ERK will be compared between patients with a tumor response and those without a response using a Wilcoxon rank sum test.

  2. Change in levels of pAKT [ Time Frame: Baseline to up to 30 days ]
    The changes from baseline will be determined and tested for statistical significance using a Wilcoxon signed rank test. The inhibition of AKT will be compared between patients with a tumor response and those without a response using a Wilcoxon rank sum test.

  3. Tumor transcriptome [ Time Frame: Up to 30 days ]
  4. Kinome analysis [ Time Frame: Up to 30 days ]
  5. Development of morbidity [ Time Frame: Up to 30 days ]
    The fraction of patients who have improvement, stability or worsening of morbidity will be determined and reported in appropriate categories depending on the initial state of their condition.

  6. Change in quality of life [ Time Frame: Baseline to up to 30 days ]
    Changes will be assessed using appropriate paired tests.

  7. Molecular analysis in tumor and blood samples [ Time Frame: Up to 30 days ]
  8. Functional improvement or decrease in pain [ Time Frame: Up to 30 days ]

Inclusion Criteria:

  • Patients must have positive genetic testing for NF1 in a Clinical Laboratory Improvement Amendments (CLIA) certified laboratory or a diagnosis of NF1 based on clinical National Institutes of Health (NIH) consensus criteria of at least one other diagnostic criterion in addition to the presence of a PN; NF1 mutation analysis will be performed on germline deoxyribonucleic acid (DNA) as described by Messiaen & Wimmer; histologic confirmation of tumor is not necessary in the presence of consistent clinical and imaging findings, but should be considered if malignant transformation of a PN is clinically suspected; additional criteria are as follows:

    • Six or more cafe-au-lait macules (>= 0.5 cm in prepubertal subjects or >= 1.5 cm in post pubertal subjects)
    • Freckling in axilla or groin
    • Optic glioma
    • Two or more Lisch nodules
    • A distinctive bony lesion (dysplasia of the sphenoid bone or dysplasia or thinning of long bone cortex)
    • A first-degree relative with NF1
  • Patients must have at least one measurable PN, defined as a lesion of at least 3 cm measured in one dimension; patients who underwent surgery for resection of a PN are eligible provided the PN was incompletely resected and is measurable as per criteria above; measurability and suitability for volumetric MRI analysis of the target PN must be confirmed with the National Cancer Institute (NCI) Pediatric Oncology Branch (POB) prior to enrolling a patient; the target PN will be defined as the clinically most relevant PN, which has to be amenable to volumetric MRI analysis; PN will be classified as ?typical PN? or ?nodular PN? versus "solitary nodular PN" prior to enrollment
  • The PN must be inoperable, defined as a PN that cannot be surgically completely removed without risk for substantial morbidity due to: encasement of or close proximity to vital structures, invasiveness, or high vascularity of the PN; the PN either causes morbidity or it is growing and has the potential to cause morbidity such as (but not limited to): head and neck lesions that could compromise the airway or great vessels, paraspinal lesions that can cause myelopathy, brachial or lumbar plexus lesions that could cause nerve compression and loss of function, lesions that could result in major deformity (e.g., orbital lesions) or are significantly disfiguring, and lesions of the extremity that cause limb hypertrophy or loss of function or pain; PN growth will be defined as a >= 20% increase in PN volume within approximately 3 years prior to enrollment on this trial
  • Patients must have a PN amenable to a percutaneous biopsy to participate in the biopsy portion of this study, and must be willing to undergo pre-, and on treatment tumor biopsies; there should be no contraindication for serial biopsies; NOTE: up to 10 patients who meet all criteria, but have PN which cannot be biopsied safely, will be eligible for the treatment portion of the study
  • Must be able to undergo serial MRI scans for response evaluation
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (patients who are wheelchair bound because of paralysis secondary to a plexiform neurofibroma should be considered ambulatory when they are up in their wheelchair; similarly, patients with limited mobility secondary to need for mechanical support (such as an airway PN requiring tracheostomy or continuous positive airway pressure [CPAP] will also be considered ambulatory for the purpose of the study)
  • Hemoglobin >= 10 g/dL (not requiring red blood cell [RBC] transfusions)
  • Absolute neutrophil count >= 1,500/mcL
  • Platelets >= 100,000/mcL (not requiring platelet transfusions)

  • Creatinine =< upper limit of normal institutional limits or creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
  • Hematologic parameters for patients undergoing biopsy only: patients should have international normalized ratio (INR) =< 1.4 and partial thromboplastin time (PTT) =< 40 seconds (unless due to lupus anticoagulant); in patients not meeting these parameters, clearance by hematology will be required prior to undergoing a biopsy
  • Normal ejection fraction (echocardiogram [ECHO]) >= 53% (if a range is given then the upper value of the range will be used) or cardiac MRI
  • Fridericia's corrected QT interval (QTcF) =< 450 msec
  • Ability of subject or legally authorized representative (LAR) to understand and the willingness to sign a written informed consent document

  • Patients with NF1 will only be eligible if complete tumor resection is not considered to be feasible without substantial risk or morbidity, or if a patient with a surgical option refuses surgery

    • Since there is no standard effective chemotherapy for patients with NF1 and PN, patients may be treated on this trial without having received prior medical therapy directed at their PN
    • Since selumetinib is not expected to cause substantial myelosuppression, there will be no limit to number of prior myelosuppressive regimen for PN or other tumor manifestations associated with NF1 such as optic glioma
    • Patients who have received previous investigational agents or biologic therapy, such as tipifarnib, pirfenidone, Peg-Intron, sorafenib, or other VEGFR inhibitors are eligible for enrollment
    • Growth factors that support platelet or white cell number or function must not have been administered within the past 7 days and are not permitted while on the study
    • At least 6 weeks must have elapsed prior to enrollment since the patient received any prior radiation therapy, and no prior radiation therapy should have been directed at the target PN
    • At least 4 weeks must have elapsed since receiving medical therapy directed at the PN
