aguix nanoparticles with radiotherapy plus concomitant temozolomide in the treatment of newly diagnosed glioblastoma

Conditions: Glioblastoma

Summary: this is a phase i/ii clinical trial evaluating the association of aguix nanoparticles with radiotherapy plus concomitant temozolomide in the treatment of newly diagnosed glioblastoma. the primary objectives of this study were to determine the recommended dose of aguix in combination with radiotherapy and tmz during the concomitant radiochemotherapy period (phase i) and to estimate the efficacy of the combination radiochemotherapy + aguix (recommended dose), measured by the 6-month progression-free survival rate (pfs) (phase ii) three dose levels of intravenous aguix nanoparticles will be explored: 50 mg/kg, 75 mg/kg and 100 mg/kg.
