Phase 2 trial of temozolomide and pegylated liposomal doxorubicin in the treatment of patients with glioblastoma multiforme following concurrent radiotherapy and chemotherapy

Abstract

Concurrent and post-radiotherapy temozolomide (T) significantly improves survival in patient with newly diagnosed glioblastoma multiforme. We aimed to assess the activity of the combination of T and pegylated liposomal doxorubicin (PLD) in this population. A combination of T (days 1-5, 200 mg/m 2 orally) and PLD (day 1, 40 mg/m 2 intravenous) was given every 4 weeks for six cycles following chemo-radiotherapy as a post-operative treatment. The primary endpoint was 6-month progression free survival (6PFS). Of the 40 patients who enrolled (53 years median age, 73% male), the 6PFS was 58% (95% confidence interval [CI], 41-72%). The median time to progression was 6.2 months (95% CI, 5.6-8.0 mont..
