Everolimus for Children With NF1 Chemotherapy-Refractory Radiographic Progressive Low Grade Gliomas
Condition: Glioma
MeSH terms: Glioma
Intervention: RAD001 (Everolimus)
Intervention description: If you take part in this research study, you will be given a participant diary for each treatment course to help you keep track of when you take your RAD001.

Summary:

      The purpose of this research study is to learn if the study drug RAD001 can shrink or slow
      the growth of low-grade gliomas in children with Neurofibromatosis type 1 (NF1).
      Additionally, the safety of RAD001 will be studied.

      The study drug, RAD001, is a drug that may act directly on tumor cells by preventing tumor
      cell growth and development. RAD001 has been studied in participants with various types of
      cancer as a single agent (a drug that is used alone to treat the cancer) or in combination
      with a number of well known anticancer therapies. Information from these research studies
      suggests that RAD001 may help to shrink or slow the growth of low-grade gliomas.

      In this research study, the investigators are looking to see the response of RAD001 in
      children with low-grade gliomas and NF1 that have either not responded to treatment or have
      come back after treatment. We are also looking for the highest dose of RAD001 that can be
      given safely in this patient population.

          -  Diagnosis: All patients must have a radiographically progressive low-grade glioma and
             at least two of the following diagnostic criteria for NF1, and/or a pathogenic NF1
             gene mutation demonstrated in peripheral blood-derived DNA:

          -  Six or more café-au-lait spots (greater than or equal to 0.5 cm in prepubertal
             subjects or greater than or equal to 1.5 cm in postpubertal subjects)

             long bone cortex)

          -  A first-degree relative with NF1

          -  An optic pathway glioma

          -  Disease Status: All patients must have radiographically progressive low-grade glioma

             require a biopsy to confirm the diagnosis.

          -  Evaluable or Measurable Disease: Patients must have at least one evaluable or
             measurable site of disease according to criteria described in Section 9. If the

             progression since the radiation.

          -  Age: Patients must be greater than 1 years and less than or equal to 21 years of age
             at the time of study entry.

          -  Performance Level: Karnofsky 50% for patients greater than 10 years of age and Lansky
             50% for patients 10 years of age (Appendix I). Note: Patients who are unable to walk
             because of paralysis, but who are up in a wheelchair, will be considered ambulatory
             for the purpose of assessing the performance score.

          -  Prior Therapy

          -  Patients must have failed or not been able to tolerate a carboplatin-based regimen.

          -  Patients must have fully recovered from the acute toxic effects of all prior
             chemotherapy or radiotherapy prior to entering this study.

          -  Myelosuppressive chemotherapy: Must not have received within 4 weeks of entry onto

             days after administration, this period must be extended beyond the time during which
             adverse events are known to occur. These patients must be discussed with the Study

          -  Enzyme inducing anticonvulsants: Patients may not be taking enzyme-inducing
             anticonvulsants, and may not have received these medications within 1 week prior to
