Brief Summary

Background: \- Plexiform neurofibromas are tumors that grow in and around nerves. The only way to treat them is with surgery. Some of these tumors cannot be completely removed. The tumors may be too large, too numerous, or in a bad location for surgery. An experimental drug called AZD6244 hydrogen sulfate may be able to prevent the tumors from growing, slow down their growth, or shrink them. This drug has been tested in adults with cancer and in children with some types of brain cancer. This study will test how well this drug works with these types of tumors. Objectives: \- To study the safety and effectiveness of AZD6244 hydrogen sulfate in children and young adults with plexiform neurofibromas that cannot be completely removed by surgery. Eligibility: \- Children and young adults between 12 and 18 years of age who have plexiform neurofibromas that cannot be completely removed by surgery. Design:

  • Patients will be screened with a physical exam, medical history, blood tests, and imaging studies.
  • They will take the study drug twice a day with 8 ounces of water, every day for 28-day cycles of treatment. During study visits, participants will have blood and urine tests and physical exams. They will also have imaging studies to examine the tumor sizes and locations. They will answer questions about their health. They may have other tests as needed.
  • Participants will continue to receive the study drug as long as they have no severe side effects and the disease is not getting worse.

Eligibility Criteria

Age2 Years - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Age Phase I: \>=3 years and \<=18 years of age at the time of study enrollment, if able to swallow whole capsules. The age limits including young children were chosen because early childhood and puberty are considered to be the greatest risk for disease progression, and selumetinib may provide the most benefit to this young group of patients. In addition, an important objective of this study is to characterize the pharmacokinetics of selumetinib in the pediatric population since it has been well studied in adults.
  • Age Phase II: \>=2 and \<= 18 years. BSA \>= 0.55 m\^2, and able to swallow whole capsules.
  • Diagnosis: Patients with NF1 and inoperable PN, defined as 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 has to cause (stratum 1) or have the potential to cause (stratum 2) significant 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, lesions of the extremity that cause limb hypertrophy or loss of function, and painful lesions. Patients will be enrolled into stratum 1 or 2 based on PN related morbidity.
  • Histologic confirmation of tumor is not necessary in the presence of consistent clinical and radiographic findings, but should be considered if malignant degeneration of a PN is clinically suspected.
  • A PN is defined as a neurofibroma that has grown along the length of a nerve and may involve multiple fascicles and branches. A spinal PN involves two or more levels with connection between the levels or extending laterally along the nerve. In addition to PN, all study subjects must have either positive genetic testing for NF1 or have at least one other diagnostic criterion for NF1 listed below: (NIH Consensus conference):
  • Six or more cafe-au-lait macules (\>=0.5cm 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
  • Measurable disease: 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.
  • Phase II: Measurability and suitability for volumetric MRI analysis of the target PN must be confirmed with the NCI 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" versus "nodular PN" versus "solitary nodular PN" prior to enrollment
  • Prior Therapy: Patients with NF1 will only be eligible if complete tumor resection is not considered to be feasible without substantial risk or morbidity.
  • 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.
  • +20 more criteria

You may not qualify if:

  • Pregnant or breast-feeding females are excluded due to potential risks of fetal and teratogenic adverse events of an investigational agent. Pregnancy tests must be obtained prior to enrollment for all females of childbearing potential as per institutional standards (at NIH subjects 9 years and older or those showing pubertal development). Males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method. Abstinence is an acceptable method of birth control.
  • Phase I: Patients who anticipate the need for surgical intervention within the first three cycles (3 months), as surgical intervention during the period of DLT evaluation may affect analysis of adherence and/or make the subject inevaluable.
  • Use of an investigational agent within the past 30 days.
  • Ongoing radiation therapy, chemotherapy, hormonal therapy directed at the tumor, immunotherapy, or biologic therapy.
  • Any evidence of severe or uncontrolled systemic disease, active infection, active bleeding diatheses, or renal transplant, including any patient known to have hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) will be excluded. Patients with HIV who have adequate CD4 count, not requiring antiretroviral medication, may be enrolled.
  • Patients who, in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study.
  • Inability to swallow capsules, since capsules cannot be crushed or broken.
  • Inability to undergo MRI and/or contraindication for MRI examinations following the MRI protocol. Prosthesis or orthopedic or dental braces that would interfere with volumetric analysis of target PN on MRI.
  • Refractory nausea and vomiting, chronic gastrointestinal diseases (e.g., inflammatory bowel disease), or significant bowel resection that would preclude adequate absorption.
  • Prior treatment with selumetinib or another specific MEK1/2 inhibitor (unless the subject meets criteria for re-treatment).
  • Evidence of an optic glioma, malignant glioma, malignant peripheral nerve sheath tumor, or other cancer requiring treatment with chemotherapy or radiation therapy.
  • Supplementation with vitamin E greater than 100% of the daily recommended dose. Any multivitamin containing vitamin E must be stopped prior to initiation of therapy.
  • Patients not achieving adequate blood pressure in spite of antihypertensive therapy for control of blood pressure.
  • Cardiac Function:
  • Known inherited coronary disease
  • +14 more criteria
