Description of intervention(s) / exposure
Anti-human EGFR (vectibix sequence)EDV'sDox (VEDVsDox) An EDV is an anucleate bacterially derived minicell. EDVs can be loaded with chemotherapy, in this case Doxorubicin. The EDV is coated with EGFR antibodies to enable it to attach to cancer cells. Eligible subjects enrolled in the study will receive VEDVsDox IV weekly as a 20 min infusion beginning at study day 1. Following the first eight doses (1 cycle) of VEDVsDox, subjects will undergo radiological assessment of their tumors with MRI prior to commencing Cycle 2. Dosing with VEDVsDox may resume at week 9 and continue until there is radiographic evidence of progressive disease (PD) per RANO criteria, the subject becomes intolerant to the study medication, signs and symptoms of clinical progression are evident as determined by the principal investigator, or the subject withdraws consent. Subsequent tumor evaluations by MRI will occur at every 8 weeks thereafter.

The study will be conducted in two parts: Part 1 - Dose Exploration and Part 2 - Dose Expansion.

Part 1 – Dose Exploration
The dose exploration part of the study is aimed at determining the maximum tolerated dose (MTD) in this patient group. A standard dose escalation with a 3x3 design will be used.

Part 1 will commence dosing at 2x10^9 VEDVsDox and escalate to 5x10^9 VEDVsDox evaluating the safety and tolerability, of VEDVsDox. Consideration will be given to further dose escalations and the possibility of exploring intermediate or lower doses depending on the safety profile.

Part 2 Dose expansion:
The dose expansion phase (Part 2) will begin upon completion of the dose exploration (Part 1). Up to 46 subjects with recurrent GBM will be treated at the Recommended Phase Two Dose (RPTD) (combining subjects enrolled in Parts 1 and 2). The sample size in the dose expansion part will vary depending on the number of subjects in Part 1 treated.

Secondary outcome [4] 301616 0
Determine the maximum tolerated dose (MTD) if feasible, of VEDVsDox in subjects with recurrent GBM
Timepoint [4] 301616 0
Patients in part 1 of the study (dose exploration phase) will have their safety information reviewed after the first 28 days on study
Secondary outcome [5] 301617 0
Estimate the time to response and duration of response as assessed by physical examination including neurological assessment and MRI scan.
Timepoint [5] 301617 0
At the end of each 8 week cycle
