Expanded Access to Gallium Maltolate (GaM)

Summary

The objective of this program is to provide GaM for compassionate use in patients with relapsed/refractory histologic or molecular glioblastoma who have exhausted available treatments. The population of this program is adult patients aged greater than or equal to 18 years with a diagnosis of relapsed/refractory histologic or molecular glioblastoma, according to the WHO 2021 diagnostic criteria. Molecular glioblastoma is characterized as an IDH-wildtype diffuse and astrocytic glioma in adults if there is microvascular proliferation or necrosis or TERT promoter mutation or EGFR gene amplification or +7/-10 chromosome copy number changes
