Berubicin in Adult Patients With Recurrent Glioblastoma Multiforme (WHO Grade IV)

This is a multicenter, open-label, Phase 1b/2 efficacy and safety study of Berubicin utilizing a Simon's 2-stage design to confirm the efficacy (or futility) of a single arm of Berubicin treatment, administered at the recommended Phase 2 dose (RP2D) identified in Phase 1 studies (7.5 mg/m2 Berubicin HCl), on the endpoint of ORR in up to approximately 61 patients. A central reader will determine the radiologic responses for each patient according to m RANO criteria. The responder criteria for this Simon's design will be based on objective response criteria defined as individual patients achieving CR or PR per m-RANO criteria within 6 months from baseline.
