This is a single centre, open label, non-randomised, single cohort, multiple dose study of Cu-67 SARTATE administered to male and female participants diagnosed with grade I, II, or III meningioma. The maximum allowable dose will be calculated using dosimetry data acquired from PET/CT scans completed during a pre-treatment diagnostic & dosimetry phase using Cu-64 SARTATE, a structurally identical molecule radiolabelled with copper-64 (Cu-64), instead of copper-67 (Cu-67). Approximately 6 participants will be enrolled in the study. Participants will have up to 4 therapy cycles (6-12 weeks apart). Safety visits will occur between each cycle at bi-weekly intervals to ensure the participant meets the safety criteria prior to their next therapy. An efficacy assessment will be conducted following cycle 2 to determine if a subsequent 2 cycles of therapy will be administered. Participants who complete all four cycles of Cu-67 SARTATE therapy, will complete their final study visit at 12 weeks post administration of cycle 4.
The primary purpose of this study is to investigate the safety and tolerability of a single dose of Cu-64 SARTATE and multiple doses of Cu-67 SARTATE administered to participants with meningioma. All participants in this study will be injected with a single dose of Cu-64 SARTATE to demonstrate how it is absorbed in the body. Then participants will receive individualised doses of Cu-67 SARTATE for up to 4 cycles.
