Detailed Description
This study is a first-in-human (FIH), Phase 1, open-label, multicentre, dose-escalation study investigating AVA6000 monotherapy administered intravenously (IV) in patients with locally advanced (unresectable) and/or metastatic solid tumours.
The study will be conducted in two parts: Phase 1a (Dose Escalation) and Phase 1b (Dose Expansion):
Phase 1a (Dose Escalation): The dose-escalation phase is designed to evaluate the safety, tolerability and MTD and/or RP2D of AVA6000, administered as monotherapy
Phase 1b (Dose Expansion): The dose-expansion phase will comprise 1 to 3 expansion arms in specific tumour types to evaluate the safety and tolerability of AVA6000 at the MTD or RP2D when administered as monotherapy. The tumour types to be explored in Phase 1b, will be determined based on evaluation of the Phase 1a data and the protocol will be amended accordingly.
