Analysis occured after all patients have been on study for 2 years. Maximum follow-up at time of analysis was 8.5 years.

What was measured

Survival time is defined as time from registration to date of death from any cause and is estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact. (Please note that this outcome measure is considered the primary endpoint for the Phase II component of the study, but that the patients from Phase I that were treated at the same dose level are included, as indicated in the treatment arm descriptions. )

Analysis population: Eligible patients on Temozolomide 100 mg arms who started study treatment
