Eligible patients will be randomized to lucanthone or placebo arm in ratio of 1:1. The treatment period will be in two phases ; an initial six weeks of concomitant therapy with temozolomide and radiation, followed by a maintenance phase of six cycles of temozolomide given on Days 1 to 5 of a 28- day cycle (+/- 3 days).
