both groups were evaluated for tumor response and progression by MRI every 8 weeks until
disease progression or discontinuation from study using RANO criteria.
Inclusion criteria:

diagnosis or prior relapse.
2. Written documentation of local or central laboratory determination of amplification or
translocation to FGFR1-TACC1, FGFR3-TACC-3 fusion and/or activating mutation in FGFR1,
FGFR2,or FGFR3
3. RANO defined tumor progression by MRI in comparison to a prior scan
4. Patients must have received prior external beam radiotherapy and temozolomide.
Exclusion criteria:
1. History of another primary malignancy
2. Prior or current treatment with a FGFR inhibitor
3. Neurological symptoms related to underlying disease requiring increasing doses of
corticosteroids
4. Patients must not be taking Enzyme Inducing Anti-Epileptic Drug (EIAED). If previously
on an EIAED, the patient must be off of it for at least two weeks prior to study
