Outcomes
Primary outcome [1] 339791 0
The primary outcome is defined as the difference of response rate on tumour measurements according to the Response Assessment in Neuro-Oncology (RANO) criteria from MRI results (i.e. sum of products of diameters (SPD). Participants will be categorised based on their SPD (i.e. change in SPD (from Screening to final standard-of-care MRI within the trial period) – In the brain or in the brain and spine.

Eligibility
Key inclusion criteria
- Equal to or greater than 18 years of age
- diagnosis of Glioblastoma multiforme (GBM)
- Have had magnetic resonance imaging (MRI) of their tumour/s within the 4 months prior to Screening Visit
- Have a Karnofsky score of equal to or greater than 50 (wheelchair bound patients due to paralysis may be considered ambulatory in assessing performance status)
- The ability to swallow liquids (Naso-gastric or gastric feeding tubes that allow the administration of Immune-12 are permitted)
- Treatment status

Group 1 (n=30)
- Patients may have undergone biopsy and/or debulking surgery,
- have undergone radiation and/or low dose temozolomide (TMZ) treatment,
- but have not yet commenced high dose TMZ treatment
- the last session of radiation was equal or greater than 4 and equal or greater than 8 weeks ago.

Group 2 (n=30)
- Patients have completed their course (regardless of the number of cycles within the course) of high-dose monthly TMZ treatment (administered 5 days per month) equal or greater than 4 equal or greater than 16 weeks ago. (That is, the 5th dose of high-dose TMZ in the final cycle of this treatment was taken equal or greater than 4 equal greater than 16 weeks ago, and no further doses of high-dose TMZ have been taken since). These participants may have commenced treatment with Lomustine, Avastin or both, or other treatments selected by the medical oncologist – the IMP can be taken concurrently with these treatments.

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be via REDCap with a hidden allocation until enrolled.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
Masking / blinding
Open (masking not used)

Statistical methods / analysis
All data will be analysed via SPSS 27.0 and/or R. Analyses will be conducted on an intention-to-treat basis with per-protocol subgroup analysis. Missing data will be imputed by multiple imputation techniques.
Descriptive statistics will summarise data and be presented as either means and standard deviations or medians with interquartile range for continuous data, or absolute and relative frequencies for categorical data.
Outcome measures RANO criteria and FACT-Br will be analysed using ANOVA with repeated measures. The significance level is set at p<0.05. The Bonferroni adjustment or the false discovery rates (FDR) will be applied to adjust the p-values in case of multiple comparisons to control the final type-I errors. Sub-analysis will occur for participants who had a biopsy versus surgical re-section. Molecular phenotype analysis will also be conducted to assess response to the intervention.
Interim analysis
An interim analysis will be conducted once 20 participants completed Week 12.
IMP compliance data
The IMP compliance data will be collated over the trial period and showcased as both absolute and relative frequencies. Compliance data will be used as a covariate for the analysis of the primary and secondary outcomes in ANCOVA and linear regression analyses.
Adverse Event data
Adverse event occurrences will be presented using absolute and relative frequencies, allowing us to quantify the prevalence of events within the dataset. This presentation will be carried out separately for both system organ classes and severity levels.
