COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - bacTRL-IL-12

Experimental: bacTRL-IL-12 - single-dose, 1 mL IV infusion of bacTRL-IL-12

Treatment: Drugs: bacTRL-IL-12
bacTRL-IL-12 is a live, genetically modified Bifidobacterium longum (B longum), for administration via IV infusion. The probiotic bacteria selectively colonize solid tumour tissues and are engineered to deliver genetic material encoding the pro-inflammatory transgene Interleukin-12 (IL-12). Plasmid DNA encoding the IL-12 transgene is delivered to the patient's cells within the tumor microenvironment, whereupon IL-12 is expressed to stimulate local and systemic anti-tumour immune responses.

Key inclusion criteria
1. Adults (18 years or older);

2. Capable of providing informed consent;

3. Advanced and/or metastatic, histologically-documented, measurable (per iRECIST) solid
tumours for which there are no other standard therapy options available that are
acceptable to the subject;

4. Eastern Cooperative Oncology Group status of 0 or 1;

5. Adequate haematological status (regardless of transfusions) defined as:

- Absolute neutrophil count = 1.5 x 109/L;

- Platelets = 100 x 109/L;

- Haemoglobin = 9g/dL;

6. Adequate renal function, defined as estimated serum creatinine clearance > 45mL/minute
calculated using Cockcroft-Gault equation

7. Adequate coagulation function, defined as:

- International Normalised Ration <1.5 x upper limit of normal (ULN) for that

- Partial thromboplastin time <1.5 x ULN

- Exception: monitoring parameters must be within therapeutic range for subjects
receiving anti-coagulation therapy

8. Adequate hepatic function, defined as:

- Total bilirubin < 1.5 x ULN unless considered due to Gilbert's disease;

- Alanine aminotransferase and aspartate aminotransferase < 1.5 x ULN or < 3 x ULN
with documented liver metastases;

9. Recovery from the toxicities of previous anti-cancer drugs or radiotherapy to Grade 0
or 1 (or to baseline if condition was pre-existing);

10. A female subject is eligible to participate if she in not pregnant, not breastfeeding,
and at least 1 of the following conditions applies:

- Not of childbearing potential, defined as surgically sterile (documented
hysterectomy, bilateral salpingectomy or bilateral oophorectomy) or
postmenopausal *no menses for 12 months without an alternative medical cause. A
high follicle stimulating hormone (FSH) level in the postmenopausal range may be
used to confirm a postmenopausal state in women not using hormonal contraception
or hormonal replacement therapy; however, in the absence of 12 months of
amenorrhea, a single FSH measurement is sufficient);

- Of childbearing potential and agrees to use a highly effective method of
contraception consistently during the treatment period and for at least 60 days
after that dose of study treatment;

11. A male subject with a female partner of childbearing potential is eligible to
participate if he agrees to use acceptable contraception during the treatment period
and for at least 60 days after the last dose of study treatment and refrains from
donating sperm during this period;

12. Agree to increase oral sugar intake during the treatment period.

Key exclusion criteria
1. Presence or history of brain metastases or abscess;

2. Presence of known or suspected ongoing ischemia of non-tumor tissues that may be
inadvertently colonized by bacteria including:

- Ischemic peripheral vascular disease, myocardial infarction within the past 6

- Congestive heart failure > class II New York Heart Association;

- Unstable angina (anginal symptoms at rest) or new onset angina (commenced within
the last 3 months);

- Patent foramen ovale;

- Prior history or current bacterial endocarditis,

- Existing thrombus (either arterial or venous) as well as known history of deep
vein thrombosis, permanent pacemakers, automated implantable
cardioverter-defibrillators, left ventricular assist devices, or other
intravascular cardiac device, known arteriovenous malformations;

- Cerebrovascular event, including transient ischemic attacks within the past 6

3. An artificial implant that cannot be easily removed (e.g., heart valves, prosthetic
hips or knees, or other devices) that could allow inadvertent bacterial colonization;

4. Abnormal fluid collections (e.g. ascites and/or pericardial and/or pleural effusions)
that could allow inadvertent bacterial colonization;

5. Has tumor masses immediately adjacent to, and/or with infiltration into, large
arteries, veins or vessels;

6. Bacteremia and/or abscess and/or treatment with systemic (oral or IV) antibiotics
within 4 weeks prior to dosing;

7. Anticipated exposure to systemic antibiotics within 4 weeks of dosing;

8. Positive for human immunodeficiency virus, hepatitis B or hepatitis C at screening;

9. Treatment with radiation therapy to a visceral organ or tumors within 2 weeks prior to

10. Treatment with any programmed cell death protein-1 and/or programmed cell death ligand
1 inhibiting agent within 2 weeks prior to dosing;

11. Treatment with any investigational agent for treatment of cancer or related
comorbidity within 4 weeks prior to dosing;

12. Treatment with any chemotherapy or major surgery within 6 weeks prior to dosing;

13. History of allergic reactions attributed to compounds of similar chemical or biologic
composition to agent(s) or other agents used in study;

14. Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, autoimmune disorder, or psychiatric illness/social situations that would
limit compliance with study requirements;

15. Any other reason that, in the opinion of the investigator and/or sponsor, precludes
the subject from participating in the trial.

Brief summary
This study is as an open-label study to be conducted at multiple study centres across New
Zealand and Australia designed to characterise the safety, tolerability and preliminary
assessment of the anti-tumour efficacy of bacTRL-IL-12 after intravenous (IV) infusion.

The study will consist of a screening period (Day -14 to Day -2), treatment and observation
(Day 1 to Day 22), safety follow-up period (Day 28 to Day 31), and efficacy follow-up period
(until progression, death, revocation of consent, or lost to follow-up).
