Safety and Efficacy Study of Lucanthone When Used in Combination With Temozolomide(TMZ) and Radiation to Treat Glioblastoma Multiforme(GBM)

This is an international, multicenter, randomized, double blind placebo controlled phase II
study to evaluate the safety and efficacy of lucanthone administered as an adjunct to

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). Lucanthone / placebo will be given as an add on in
both concomitant and maintenance phases.
