Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Mitoxantrone packaged EDV (EnGeneIC Delivery Vehicle)

Experimental: Mitoxantrone packaged EDV - Mitoxantrone packaged EDV (EnGeneIC Dream Vector)


Treatment: Drugs: Mitoxantrone packaged EDV (EnGeneIC Delivery Vehicle)
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.

Eligibility
Key inclusion criteria
- Patients must be = 2 years and = 21 years old at the time of study enrolment.

- Karnofsky = 50% for patients > 16 years of age and Lansky = 50 for patients = 16 years
of age

- Patients must have relapsed or refractory solid or CNS tumours or have a diagnosis of
DIPG. Patients must have had histologic verification of malignancy at original
diagnosis or relapse, or a diagnosis of DIPG by MRI imaging.

- Patients must have either measurable or evaluable disease for Part B of the study only

- Patient's current disease state must be one for which there is no known curative
therapy or therapy proven to prolong survival with an acceptable quality of life.

- Patients must have fully recovered from the acute toxic effects of all prior
chemotherapy, immunotherapy, or radiotherapy prior to entering this study
Minimum age
2 Years
Maximum age
21 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Pregnant or breast-feeding women will not be entered on this study.

- Any active uncontrolled infection

- Patients who are known to be serologically positive for Hepatitis A, B or C, or have a
history of liver disease, other forms of hepatitis or cirrhosis.

- Known positive test for human immunodeficiency virus infection

- Patients with disease of any major organ system that would compromise their ability to
withstand therapy

- Concurrent or prior (within 7 days of enrolment) anticoagulation therapy, except low
molecular weight heparins or low dose aspirin

- Patients receiving corticosteroids must be on a stable dose that has not been
increased for at least 7 days prior to study enrolment.

- Patients who are currently receiving another investigational drug are ineligible.

- Patients who are currently receiving other antineoplastic agents are ineligible.

- All herbal supplements, vitamins, and nutritional supplements taken within the last 30
days prior to dosing on Day 1 (and continued use, if appropriate), must be reviewed
and approved by the Study Chair.

- Patient will not be available for protocol-required study visits or procedures, to the
best of the subject/parent/guardian's and investigator's knowledge.

- Patient has any kind of disorder that, in the opinion of the investigator, may
compromise the ability of the subject/parent/guardian to give written informed consent
and/or to comply with all required study procedures.

- History or evidence of any other clinically significant disorder, condition or disease
(with the exception of those outlined above) that, in the opinion of the investigator
would pose a risk to subject safety or interfere with the study evaluation, procedures
or completion.

- Patients will be screened for antibodies to S. typhimurium and will not be eligible
until antibodies are non-detectable

- Patients will be screened for IL6 and TNFa cytokines and will not be eligible until
levels are less than 3x times the detectable limit of the assay.
