Study Arms:
- Dose Determination (Type: EXPERIMENTAL): The recommended dose (RD) for Proxinium is to be determined based on the rate of Dose Limiting Toxicities (DLT) within each dose cohort. The RD is to be established as the highest dose at which one or fewer patients out of six within a dose cohort experienced a DLT. The initial dose level is 500 μg of Proxinium in PBS (the amount of PBS used will be based on the estimated volume of the target tumour). Doses are to be escalated to a maximum of 700 μg or de-escalated to a minimum of 260 μg according to the prescribed algorithm outlined in the study protocol.

Based on this trial design, predict the completion outcome and termination type (if applicable).
