|NCT01158651 : Study of RAD001 (Everolimus) for Children With NF1 and Chemotherapy-Refractory Radiographic Progressive Low Grade Gliomas|
|Ages||Min: 1 Year Max: 21 Years|
- 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)
- Freckling in the axilla and/or inguinal region
- Plexiform neurofibroma
- 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
- An optic pathway glioma
- Disease Status: All patients must have radiographically progressive low-grade glioma
(including NF1 related visual pathway gliomas) after failure of a
carboplatin-containing regimen. Patients with recurrent/progressive disease do not
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
patient has had previous radiation to the marker lesion(s), there must be evidence of
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
this study (6 weeks if prior nitrosourea).
- Hematopoietic growth factors: At least 7 days since the completion of therapy with a
- Biologic (anti-neoplastic agent): At least 14 days since the completion of therapy
with a biologic agent. For agents that have known adverse events occurring beyond 14
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
Chair on a case-by-case basis.
- Investigational Drugs: Patients must not have received an investigational drug
within 14 days.
- Steroids: Patients with endocrine deficiencies are allowed to receive physiologic or
stress doses of steroids if necessary.
- CYP3A4 inhibitors: Patients may not be currently receiving strong inhibitors of
CYP3A4, and may not have received these medications within 1 week prior to study
entry. These include:
- Antibiotics: clarithromycin, erythromycin, troleandomycin Anti-HIV agents:
delaviridine, nelfinavir, amprenavir, ritonavir, indinavir, saquinavir, lopinavir
- Antifungals: itraconazole, ketoconazole, fluconazole (doses greater than 200 mg/day),
- Antidepressants: nefazodone, fluovoxamine Calcium channel blockers: verapamil,
- Miscellaneous: amiodarone,
- In addition, grapefruit juice should be avoided, as it inhibits CYP3A4.
- CYP3A4 inducers: Patients must also avoid St. John's Wort, an inducer of CYP3A4
- Enzyme inducing anticonvulsants: Patients may not be taking enzyme-inducing
anticonvulsants, and may not have received these medications within 1 week prior to
study entry, as these patients may experience different drug disposition. These
- Carbamazepine (Tegretol)
- Felbamate (Felbtol)
- Phenytoin (Dilantin)
- Primidone (Mysoline)
- Oxcarbazepine (Trileptal)
- 6 months must have elapsed if the patient has received involved field XRT or gamma
knife that includes all target lesions (i.e., there is no restriction if a new lesion
arises outside the radiation field or a non-irradiated lesion progresses);
- 6 months must have elapsed if the patient has received craniospinal XRT.
- 6 weeks must have elapsed if patient has received radiation to areas outside optic
- Surgery: At least 2 weeks must have elapsed since undergoing major surgery.

nerve sheath tumor, or other cancer requiring concurrent treatment with chemotherapy
or radiation therapy. Patients not requiring treatment for these lesions are
eligible for this protocol.
