Multicenter, Open-Label Study with a Randomized Control Arm of the Efficacy, Safety, and Pharmacokinetics of Intravenously Infused Berubicin in Adult Patients with Recurrent Glioblastoma Multiforme (WHO Grade IV) After Failure of Standard First Line Therapy
This is an open-label, multicenter, randomized, parallel, 2-arm, efficacy and safety study. Patients with GBM after failure of standard first line therapy will be randomized in a 2:1 ratio to receive berubicin or lomustine for the evaluation of OS. Additional endpoints will include response and progression outcomes evaluated by a blinded central reviewer for each patient according to RANO criteria.
A pre-planned, non-binding futility analysis will be performed after approximately 30 to 50% of all planned patients have completed the primary endpoint at 6 months. This review will include additional evaluation of safety as well as secondary efficacy endpoints. Enrollment will not be paused during this interim analysis.
Inclusions/Exclusions: Recurrent GBM as evaluated by RANO criteria, Tumor is localized supratentorially. Lesion (or sum of lesions) does not exceed 50 cm3 in volume. No more than 1 prior line of treatment (eg, surgery followed by radiation with concomitant chemotherapy, followed by adjuvant chemotherapy is considered as 1 line of treatment). A second debulking surgery during the first line treatment is acceptable. In addition, treatment with tumor treating fields (TTFields; Optune) is acceptable if provided as first line therapy.
