Study type
Description of intervention(s) / exposure
TargomiRs are targeted minicells containing a microRNA mimic. They consist of three components: 1. A miR-16-based microRNA mimic. The miR-16 family has been implicated as a tumour suppressor in a range of cancer types. The mimic is a double-stranded, 23 base pair, synthetic RNA molecule. 2. Drug delivery vehicle – EDVs. EDVs are nonliving bacterial minicells (nanoparticles). They function as leak resistant micro-reservoir carriers that allow efficient packaging of a range of different drugs, proteins or nucleic acids. 3. Targeting moiety. The EDVs are targeted to EGFR-expressing cancer cells with an anti-EGFR bispecific antibody.

TargomiRs are IV injected.

Phase 1
Planned dose levels

Dose level 1: 5 billion once a week
Dose level 2: 5 billion twice a week
Dose level 3: 5 billion once a week with cardiac monitoring
Dose level 4: 2.5 billion twice a week with cardiac monitoring
Dose level 5: 2.5 billion twice a week with dexamethasone challenge and cardiac monitoring

All patients begin on modified, micro doses to allow the body the opportunity to adjust to the introduction of EDVs into the body. The full phase 1 dose for a patient is reached in treatment week 3.

Duration of treatment for each dose level is on a patient by patient basis. Officially the cycle is 8 weeks long however a patient can continue on treatment if they are deriving clinical benefit from the treatment.
If at any time point before or after the 8 week mark, a patient progresses, experiences ongoing or unreasonable toxicities or withdraws from the study, they will cease treatment.

Escalation of dose in cohorts of 3-6 patients per dose level. If at least 2 patients are observed to experience Dose Limiting Toxicity (DLT), the prior dose level is defined as the MTD.

Cardiac monitoring includes a Sestamibi scan and Echo before the patient begins on TargomiR treatment and if any cardiac changes are observed whilst the patient receives treatment, these scans are to be repeated and a Troponin blood level obtained. ECGs are obtained on the same schedule as all previous cohorts.

Dexamethasone is one of the pre-medications given prior to TargomiRs. The dexamethasone challenge seeks to reduce the amount of dexamethasone given to patients during the course of their treatment period.
The schedule is to reduce the dose from 4mg to nil over the course of 8 weeks so long as the patient does not experience undue allergic actions to the TargomiRs.

Adherence to the protocol tends not to be problematic in patient groups where the trial treatment is their only treatment option. They are often very keen to participate and motivated to be part of the research.

Treatment: Drugs
Comparator / control treatment
No control
Control group

Primary outcome [1] 292244 0
There is a composite primary outcome to establish maximum tolerated dose and dose limiting toxicities.

The MTD will be determined by the assessment of dose limiting toxicities. Toxicities, in the first 2 weeks of treatment for any given patient, are assessed with physical assessments 5 times in the 24 hours starting with a pre-dose assessment, and with laboratory assessments which are assessed 3 times in the 24 hours starting with pre-dose assessment.
All adverse events are graded according to the CTCAE v4.0.

Timepoint [1] 292244 0
DLTs specifically are assessed in the first 2 weeks of a patient's treatment.
patients are assessed 3 times/ 24 hours from pre-dose timepoint for blood changes and 5 times/ 24 hours from pre-dose timepoint for physical changes.
(From week 3 onwards, labs are checked twice in 24 hours and physical assessments performed 3 times in 24 hours.)

MTD is declared when a maximum of 1 patient out of 6 experiences a DLT at the dose level below the maximally administered dose.
Primary outcome [2] 292246 0
to evaluate the effect of multiple dosing of TargomiRs using physical and lab assessments as well as tumour response via PET/CT.
Timepoint [2] 292246 0
the laboratory and physical assessments are conducted multiple times in a 24 hour period starting with pre-dose assessments for each dose received until the patient comes off treatment. At the end of an 8 week cycle, PET/CT is also used for tumour measurement.
Primary outcome [3] 292247 0
to detect early signs of efficacy using QoL questionnaires and tumour response via PET/CT.
Timepoint [3] 292247 0
8 weeks, when formal assessment with RECIST applied and QoL questionnaires assessed.
Secondary outcome [1] 308535 0
QOL assessment (EORTC QLQ-C30 (Version 3))
Timepoint [1] 308535 0
Patients will complete a QoL questionnaire prior to each dose they receive. These questionnaires will be evaluated after each 8 week cycle (or when the patient finishes treatment prior to 8 weeks).
Secondary outcome [2] 308536 0
to monitor changes in ECOG PS during treatment
Timepoint [2] 308536 0
ECOG PS will be assessed prior to each dose the patient receives.
Any change occurring in ECOG over the course of treatment will be evaluated at the end of an 8 week cycle or when a patient comes off treatment prior to that.
Patients are required to have an ECOG of 0 or 1 to come on the trial. If their ECOG ever drops to a 2 or below, they will assessed for suitability to continue.
Secondary outcome [3] 308537 0
to monitor pulmonary function parameters during treatment using FEV1 and Vital Capacity measurements.
Timepoint [3] 308537 0
Pulmonary function is measured in screening and at follow up after the patient comes off treatment.

Study design
Purpose of the study
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A potential patient will undergo general screening according to the inclusion and exclusion criteria. When screening requires study specific procedures, a patient will go through the informed consent process and after signing consent will complete the specific screening elements by site staff.
When a site deems a patient eligible for registration on the study, ADRI (the sponsor) will be responsible for monitoring eligibility and then registering a patient. There is only 1 arm and 1 treatment on this trial. If a patient is registering onto Phase 1, they will be allocated into the next space available which may be the same dose escalation cohort as the previous patient, or the next cohort if the previous cohort is complete.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
There is no randomisation process on this trial. Participants will be registered. They will be numbered sequentially taking into account what number patient they are on the trial, what cohort they are part of and what position within the cohort they are.

Brief summary
This study will evaluate the safety and effect of a new treatment known as TargomiRs in patients with malignant pleural mesothelioma (MPM) and non-small cell lung cancer (NSCLC).
Who is it for? You may be eligible to join this study if you are aged 18 years or above, and have a confirmed diagnosis of MPM or NSCLC, with evidence of Epidermal growth factor receptor (EGFR) in tumour tissue.
Study details: All participants in this study will receive treatment with a new targeted therapy known as TargomiRs. Treatment will be administered by injection into the vein (i.e. intravenously) at a frequency of once or twice weekly until it is clear that you are not benefitting from the treatment. Initially a low dose will be administered to participants. If this dose is tolerated, then it will be increased in the next group of patients and so on until the maximum tolerated dose is determined. All participants will be regularly monitored for safety and toxicity of the treatment for 24 hours after each treatment in the first 2 weeks and 3 hours after treatment from week 3 onwards. They will also be required to complete QoL questionnaires each treatment and have PET scans and lung function tests approximately once every 8 weeks in order to evaluate treatment effect and quality of life.
It is hoped that the treatment offered will cause the diseased tissues to respond in a way that will block uncontrolled tumour growth resulting in tumour control and give patients a longer life.
