Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Study medication is introduced in a step-wise manner, starting 4 weeks after completion of surgery and radiotherapy and the first cycle of chemotherapy (Temozolomide (TMZ)).

The study treatment consists of six oral medications. The dosage of the medications is increased over a 4 week period, and the treatment is maintained for the duration of the study. The total duration of the study is 4 years.

The dosing regime is as follows;
1) Propranolol; week 0 - 40mg twice daily, week 1 - 80mg morning, 40mg evening, continue at this dose for the remainder of the study
2) Aliskiren; week 0 - 150mg once daily, continue at this dose for the remainder of the study
3) Curcumin with piperine; week 0 - 1000mg twice daily, continue at this dose for the remainder of the study
4) Celecoxib; introduced at week 4 - 200mg once daily, continue at this dose for the remainder of the study
5) Metformin; week 0 - 250mg once daily, week 1 - 250mg twice daily, week 3 - 500mg morning, 250mg evening, week 4 - 500mg twice daily, continue at this dose for the remainder of the study
6) Quinapril; introduced at week 2 - 5mg once daily, week 3 - 10mg once daily, week 4 - 20mg once daily, continue at this dose for the remainder of the study

Renal function, platelet count, blood pressure and pulse rate are monitored.

Efficacy
Statistical methods / analysis
For the primary outcome of survival time from diagnosis, assuming exponential distribution of survival times a sample size of 75 patients will provide a 95% confidence interval of +/- 4 months for the overall median survival time. This assumes 30% censoring.

The data will be analysed using survival analysis methods (Kaplan-Meier survival curves and Cox’s proportional hazards model) so that all patients (whether or not they have died) will provide information for the estimation of overall median survival time. Analysis of both survival time from diagnosis and survival time from initiation of the intervention will be examined. The analysis of tumour progression (tumour volume and avidity) measured by FET-PET, will use non-parametric methods, as will the analysis of change in QoL. Graphical methods (plots of mean QoL score and their 95% confidence intervals) will be used to describe the changes over time. Analysis will be stratified according to IDH genotype and MGMT methylation, however, subgroup analysis will not be possible due to sample size.

Summary
Brief summary
This study aims to evaluate the efficacy of treating glioblastoma patients with oral medications that target the renin-angiotensin system, and are commonly used for treating other conditions.

Who is it for?
You may be eligible for this study if you are aged 16 to 80 years and have histologically confirmed glioblastoma for which you have completed surgery (biopsy or debulking) and chemoradiotherapy involving Temozolomide, or radiotherapy alone.

Study details
Participants will be given gradually increasing doses of oral medications including Aliskiren, Celecoxib, Curcumin, Metformin, Propranolol and Quinapril for up to 4 years. Data will be collected on overall survival, progression of glioblastoma tumour, quality of life and performance status.

It is hoped that data from this study will determine the efficacy of treatment targeting the renin-angiotensin system in glioblastoma patients.
