Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Neoantigen peptide vaccine containing 5 - 10 peptides per vaccine depending on how many high affinity binding neo-antigens are predicted for each patient (ie some patients may only have 5 high affinity neo-antigens identified)
The vaccine will be administered 2 weekly for 4 doses then 4 weekly for 4 doses as a subcutaneous injection (fortnightly for the first 4 doses then 4 weekly for the next 4 doses)

Patients are provided with treatment schedule and will be reviewed by clinician prior to each dose for safety monitoring. CRFs will be completed for each visit.

Each dose will include 500mcg - 1000mcg of synthetic peptide (100mcg per peptide) in 0.5mL of Montanide as adjuvant by subcutaneous administration

Can healthy volunteers participate?
No
Key exclusion criteria
1. Received chemotherapy, radiotherapy, or biologic therapy or other investigational therapeutic agent(s) within the last 21 days
2. Ongoing adverse effects from chemotherapy that have not resolved to = grade 1 (except haemoglobin= 90g/L is allowed)
3. Known allergy, or history of serious adverse reaction to vaccines such as anaphylaxis, urticaria, or respiratory difficulty.
4. Uncontrolled significant intercurrent illness of major organ systems, or has psychiatric illness/social situation that would limit compliance with study requirements.
5. Prior or currently active significant autoimmune disease. Subjects with Type I diabetes mellitus, hypothyroidism requiring only hormone replacement are permitted to enroll.

10. Known medical condition that, in the investigator’s opinion, would increase the risk associated with study participation or study drug administration or interfere with the interpretation of safety results.
11. Subjects in whom the ability to observe possible local reactions at the eligible injection sites is, in the
opinion of the investigator, unacceptably obscured due to a physical condition or permanent body art.
