|NCT01386450 : AZD6244 in Children With Low-Grade Gliomas|
|Phase||Phase 1/Phase 2|
|Ages||Min: 3 Years Max: 21 Years|
- INCLUSION CRITERIA
Patients with sporadic (non NF-1 associated), histologically diagnosed pilocytic
astrocytoma who have pre- treatment tumor tissue available for BRAF analysis are eligible.
NF-1 patients with radiographic evidence of low grade glioma, with or without histological
diagnosis are also eligible. Patients will be assigned to one of 4 strata following
- Stratum 1: Patients with progressive, recurrent or refractory pilocytic astrocytoma
with pre-trial tumor material available and with a BRAF aberration i.e. BRAF (V600E)
mutation and/or BRAF KIAA1549 fusion as determined by IHC and FISH, respectively.
- Stratum 2: Patients with progressive, recurrent or refractory pilocytic astrocytoma
with pre-trial tumor material available and without a BRAF aberration i.e. BRAF
(V600E) mutation and/or BRAF KIAA1549 fusion as determined by IHC and FISH,
- Stratum 3: Patients with Neuro-fibromatosis 1 (NF-1) associated progressive,
recurrent or refractory low grade glioma (WHO Grade I & II), with or without tissue
- Stratum 4: Non-NF-1 recurrent or refractory pilocytic astrocytoma patients who cannot
be classified into Stratum 1 or 2 due to inadequate tissue quality or assay failure.

decreasing dose for at least 1 week prior to registration.

least 1 week prior to registration (filgrastim, sargramostim, erythropoietin) and at least
2 weeks for long-acting formulations.

95th percentile for age, height and gender at the time of registration.
--The normal blood pressure by height, age and gender tables can be accessed in the
Generic Forms section of the PBTC members webpage.
- Patients who are greater than or equal to 18 years of age must have a blood pressure
that is < 140/90 mm of Hg at the time of registration.
Note: If a BP reading prior to registration is above the 95th percentile for age, height

percentile for age, height and gender prior to patient registration.
3.1.11 Pregnancy Status
Female patients of childbearing potential must not be pregnant or breast-feeding. Female
patients of childbearing potential must have a negative serum or urine pregnancy test.
3.1.12 Pregnancy Prevention
The effects of AZD6244 on the developing human fetus are unknown. For this reason, women
of child-bearing potential and men must agree to use adequate contraception (hormonal or
barrier method of birth control; abstinence) prior to study entry and for the duration of
study participation, and for four weeks after dosing with AZD6244 ceases. Women of
child-bearing potential must have a negative pregnancy test prior to entry. Should a woman
become pregnant or suspect she is pregnant while she or her partner is participating in
this study, she should inform her treating physician immediately. Please note that the
AZD6244 manufacturer recommends that adequate contraception for male patients should be
used for 16 weeks post-last dose due to sperm life cycle.

events (e.g., heart failure, hypokalemia, family history of long QT interval syndrome)
