|---|---|
| Main Objective: The main objective of the study is to show that the combination of imatinib mesylate (GLIVEC) and hydroxyurea is superior to hydroxyurea alone in prolonging progression free survival (PFS) of patients with GBM according to Macdonald-criteria.;Secondary Objective: •Assessment of overall survival during the study. •Assessment of duration of response, whereby response is defined as at least according to the Macdonald-criteria or partial response (PR) according to the Macdonald-criteria. •Assessment of response status (overall response) with a combination of imatinib mesylate and hydroxyurea or hydroxyurea alone, i.e. relative number of patients with at least according to Macdonald-criteria or with at least PR or CR according to the Macdonald-criteria. •To assess the clinical benefit of the combined treatment of imatinib mesylate with HU, or of HU alone. The clinical benefit will be assessed based on the overall response (OR) plus stable disease (SD) lasting more than six months (OR + (SD>6 months)). ;Primary end point(s): Rate of patients with progression free survival (PFS) during entire study. | — |
