The standard therapy of glioblastoma (GBM) consists of gross total resection followed by focal irradiation to the tumor bed with concomitant and adjuvant temozolomide (TMZ). The association of valproic acid and TMZ during radiotherapy improves survival of GBM. Preclinical studies suggested that doxorubicin had a strong antineoplastic activity against human gliomas. Moreover, some studies showed that the continuous infusion of anthracyclines in patients with solid tumor ensured a better safety profile compared with bolus administration.
Based on these findings, the purpose of this study is to evaluate safety and efficacy of prolonged administration of doxorubicin in combination with radiotherapy, temozolomide and valproic acid in pediatric and adult patients with newly diagnosed GBM and diffuse intrinsic pontine glioma (DIPG).

|Official Title:||An Open-label, Single-arm, Phase II Study to Evaluate Safety and Efficacy of Doxorubicin in Combination With Radiotherapy, Temozolomide and Valproic Acid in Patients With Glioblastoma Multiforme (GBM) and Diffuse Intrinsic Pontine Glioma (DIPG)|
|Study Start Date :||February 2016|
|Estimated Primary Completion Date :||July 2020|
|Estimated Study Completion Date :||July 2020|
Patients are treated with Weller-Stupp protocol: initial radiotherapy (1.8 Gy/die, days 1-5; total dose 54-60 Gy) with concomitant oral temozolomide (75mg/m2/die, days 1-7) per 6 weeks.
At week 10 (4 weeks after the chemo-radiotherapy treatment completion): 1 cycle of oral temozolomide (150-180 mg/m2, days 1-5)
At week 14 (8 weeks after the chemo-radiotherapy treatment completion) 1 cycle of prolonged infusion of Doxorubicin (25mg/m2/die in 24 hours, days 1-4; total cumulative dose 100 mg/m2).
At week 18 (4 weeks after the end of doxorubicin administration): 16 cycles of oral temozolomide (initial dose of 150 mg/m2 increasing to 180 mg/m2 days 1-5, 28-day cycle).
Oral valproic acid (20-30 mg/Kg/die bid) is administered from week 1 until the last treatment day.
