This is an open-label non-randomized, multicenter, phase II study of BGJ398 administered to adult patients with histologically confirmed GBM and/or other glioma subtypes with FGFR1-TACC1, FGFR3-TACC3 fusion and/or activating mutation in FGFR1, 2 or 3.

Patients were enrolled in two groups. Group 1 enrolled patients who are not candidates for surgery. Group 2 was planned to enroll patients who are surgical candidates. Patients from 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:

1. Patients with histologically confirmed GBM and/or other glioma subtypes at the time of 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 treatment.
