Mitoxantrone packaged EDV (EnGeneIC Dream Vector)

EnGeneIC Delivery Vehicles (EDVs) are nanocells which can be loaded with anti-cancer drugs (mitoxantrone in this study) and targeted to tumor cells. These bacterially-derived nanocells are coated in bispecific antibodies (BsAb) that recognize oncogenic receptors on the tumor cell surface. Once bound to the tumour cell, the targeted and drug-loaded EDVs are endocytosed and release their toxic payload to destroy the tumor cell.

This is an open-label, sequential dose exploration study of single agent EEDVSMit administered by intravenous (IV) infusion twice weekly, followed by weekly maintenance dosing, in children with recurrent/refractory solid or CNS tumours.

Eligible subjects enrolled in the study will receive EEDVSMit by IV injection twice weekly as a 20 min infusion beginning at study day 1 for the first cycle (4 weeks) then weekly for subsequent cycles. Subjects will undergo radiological assessment of their tumours after the first cycle, and every second cycle thereafter. Dosing with EEDVSmit will continue unless there is radiographic evidence of progressive disease (PD) per RECIST criteria version 1.1, 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/parent/guardian withdraws consent. Suspected tumour progression should be confirmed with a repeat scan after 4 weeks to exclude the possibility of pseudoprogression.

Determination of EGFR expression for eligibility of subjects will be assessed at the local site. In addition, radiological assessment confirming measurable disease by the RECIST criteria is also required for entry into the Part B of the study.

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

Part A - Dose Exploration:

The dose exploration part of the study is aimed at determining a recommended phase 2 dose (RP2D) in this patient group. A standard dose escalation with a rolling 6 design will be used.

Part A will commence dosing at one log scale below the maximum dose tested in the recent adult recurrent glioma trial (with the first 4 doses administered at 1/10 of the starting dose) and escalate to a maximum of 8x109 EEDVSMit evaluating the safety and tolerability, of EEDVSMit. The first 4 doses administered will be reduced by a further log reduction.

Part B - Dose expansion:

The dose expansion phase (Part B) will begin upon completion of the dose exploration (Part A). Up to 12 subjects with recurrent/refractory solid or CNS tumours will be treated at the Recommended Phase Two Dose (RPTD). All doses, including the first 4, will be at the same dose level established in Part A (RPTD).

A Phase 1 Study of Intravenous EGFR-ErbituxEDVsMIT (EEDVsMit) in Children With Recurrent / Refractory Solid or CNS Tumours Expressing Epidermal Growth Factor Receptor (EGFR) (ECREST Study)

De-identified data is planned to be shared with EnGeneIC.

To determine a recommended phase 2 dose (RP2D) for EEDVsMit administered intravenously in children with recurrent / refractory solid or CNS tumours expressing EGFR

To define and describe the toxicities of EEDVSMit administered on these schedules in children with recurrent/refractory solid or CNS tumours

Assess the safety and tolerability of EEDVSMit in children with recurrent/refractory solid or CNS tumours.

To preliminarily define the anti-tumour activity of EEDVSMit and assess response rates using RECIST version 1.1 criteria in children with recurrent/refractory solid or CNS tumours within the confines of a phase 1 study.

Assess overall survival (OS) in children with recurrent/refractory solid or CNS tumours treated with EEDVSMit on this schedule
