INC280 Combined With Bevacizumab in Patients With Glioblastoma Multiforme

Despite recent advances, glioblastoma multiforme (GBM) remains an incurable malignancy with a
short expected survival. c-MET signalling promotes invasive growth and has been described in
various cancers. INC280 is a highly potent and selective c-MET inhibitor which also
penetrates the blood-brain barrier. In this open-label, multicenter Phase 1b study,
investigators determined the optimal dose of the INC280/bevacizumab combination to administer
to patients. Enrollment has now expanded in order to treat 3 cohorts of GBM patients: those
who progressed after ≥ first-line standard therapy, those who progressed after ≥ second-line
therapy with INC280/bevacizumab, and those with unresectable GBM.

Inclusion Criteria:

KEY POINTS:

1. Dose Escalation Phase: Histologic diagnosis of GBM or gliosarcoma. Progressed during
or after standard 1st-line therapy for GBM. Patients scheduled to undergo a repeat
primary surgical resection are also eligible. Measurable disease as measured by RANO
(Response Assessment in Neuro-Oncology) criteria.

2. Dose Expansion Phase:

Cohort A: Histologic diagnosis of GBM. Patients should have progressed during or after
standard 1st-line therapy. Patients scheduled to undergo a repeat primary surgical
resection are also eligible. Measurable disease as measured by RANO criteria.

At least 5 patients must have an alteration of MET [as assessed by fluorescence in
situ hybridization (FISH) (c-MET/centromere ratio ≥2, or c-MET gene copy number ≥ 5)
or RT-PCR or Met immunohistochemistry (IHC) score of 2-3+ or a mutation].

Cohort B: Histologic diagnosis of GBM patients who have progressed during or after
2nd-line therapy with bevacizumab or a bevacizumab-based regimen. Measurable disease
according to RANO criteria.

Cohort C: Histologic diagnosis of GBM by stereotactic biopsy in patients with
unresectable brain tumors.

3. Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0-2 or Karnofsky
Performance Scale (KPS) of at least 70%.

4. Adequate hematologic, renal and liver function

5. Life expectancy ≥ 3 months

6. Availability of archived tumor samples and/or willingness to provide tissue samples if
resection is done. (Fresh tissue biopsy is not required if archival tissue is not
available.)

Exclusion Criteria:

1. Prior treatment with bevacizumab for GBM patients eligible for Cohorts A and C. (Prior
treatment with bevacizumab is permitted for GBM patients eligible for Cohort B only.)

2. Most recent chemotherapy ≤ 21 days to the start of treatment and ≥ Grade 2
chemotherapy-related side effects with the exception of alopecia.

3. Use of any investigational drug ≤ 21 days to the start of treatment or 5 half-lives
(whichever is shorter) prior to the first dose of INC280 with bevacizumab. For study
drugs for which 5 half-lives is ≤ 21 days, a minimum of 10 days between termination of
the study drug and the start of treatment is required.

4. Uncontrolled seizures (Patients with a history of seizures are eligible if they are
currently without seizures on a stable dose of anti-epileptic drugs for 14 days prior
to enrollment.)

5. History of uncontrolled hereditary or acquired bleeding or thrombotic disorders.

6. Major surgery ≤ 28 days to the start of treatment, or subcutaneous venous access
device placement ≤ 7 days to the start of treatment

7. A serious non healing wound, ulcer, or bone fracture ≤ 28 days to the start of
treatment

8. Wide field radiotherapy (including therapeutic radioisotopes such as strontium 89)
administered ≤ 28 days or limited field radiation for palliation ≤ 7 days prior to
starting study drug or has not recovered from side effects of such therapy.

9. Leptomeningeal metastases or spinal cord compression due to disease.

10. Women of child-bearing potential.

11. Receiving drugs known to be strong inhibitors or inducers of CYP3A4 and cannot be
discontinued 7 days prior to the start of INC280 treatment and during the course of
the study, or medications that are known CYP3A4, CYP1A2, CYP2C8, CYP2C9 or CYP2C19
substrates with narrow therapeutic index, and cannot be discontinued during the course
of the study.

12. Treatment with proton pump inhibitors within three days prior to study entry.

13. Cardiac disease currently or less than 6 months from baseline screening

14. Inadequately controlled hypertension (i.e., systolic blood pressure [SBP] >180 mmHg or
diastolic blood pressure (DBP) >100 mmHg) (patients with values above these levels
must have their blood pressure (BP) controlled with medication prior to starting
treatment).

15. Currently receiving treatment with therapeutic doses of warfarin sodium. Low molecular
weight heparin is allowed.
