Filter by:The primary objective of this Phase 1, open-label, dose-escalation, and exploratory study is to evaluate the safety and tolerability profile (establish the maximum-tolerated dose) and evaluate the occurrence of dose-limiting toxicities (DLTs) following single weekly or multiple-day weekly dose regimens of single-agent, oral ONC206 in patients with recurrent, primary central nervous system (CNS) neoplasms.
The HIT-HGG-2013 trial offers an innovative high-quality diagnostics and science program for children and adolescents >3 years, suffering from one of the following types of high grade gliomas: 1. glioblastoma WHO grade IV (GBM) 2. diffuse midlineglioma histone 3 K27M mutated WHO grade IV (DMG) 3. anaplastic astrocytoma WHO grade III (AA) 4. diffuse intrinsic pontine glioma (DIPG) 5. gliomatosis cerebri (GC) For 1.-3. diagnosis has to be confirmed by neuropathological survey, for 4. and 5. diagnosis has to be confirmed by neuroradiological survey. In addition to standard treatment (radiotherapy and temozolomide chemotherapy) the effect of valproic acid which is traditionally used for treatment of seizure disorder, will be investigated. The aim of the trial will be to investigate whether this drug may increase the effects of radio- and chemotherapy, resulting in a better survival of the treated patients. Scientific studies provided evidence for anti-tumoral effects of valproic acid: the drug seems to be a so-called histondeacetylase inhibitor (HDAC inhibitor), controlling important genetic processes of tumor growth. Studies in cell culture, animals and first clinical trials in adults as well provided evidence for efficacy of valproic acid in the treatment of glioblastoma. Due to this we hope children and adolescents suffering from GBM, DMG, AA, DIPG und GC will benefit from the treatment, too. The aim of the HIT-HGG-2013 trial will be to compare the effects of Valproic acid with data of the HIT-HGG-2007 trial (children and adolescents with same diseases, only treated with simultaneous temozolomide radiochemotherapy). In the present study, it was originally planned to investigate the therapeutic efficiency and safety of valproic acid and the autophagy inhibitor chloroquine, both in addition to temozolomide therapy. Since distribution of Resochin junior (chloroquine phosphate) was terminated, recruitment of new patients was stopped on August 8, 2019. For continuation of the trial, the chloroquine arm was closed but the patients already recruited in this arm will be followed up.
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).
Currently, there are few effective treatments for the following aggressive brain tumors: glioblastoma multiforme, anaplastic astrocytoma, gliomatosis cerebri, gliosarcoma, or brainstem glioma. Surgery and radiation can generally slow down these aggressive brain tumors, but in the majority of patients, these tumors will start growing again in 6-12 months. Adding chemotherapy drugs to surgery and radiation does not clearly improve the cure rate of children with malignant gliomas. The investigators are conducting this study to see if the combination of valproic acid and bevacizumab (also known as AvastinTM) with surgery and radiation will shrink these brain tumors more effectively and improve the chance of cure.
