Conditions
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.
Interventions
All trial drugs are administered orally, and will be introduced in a step-wise fashion, with each drug titrated until the optimal dose as per the protocol. 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 approximately 4 years. The dosing regime is as follows; 1) Aliskiren - week 0 - 150mg once daily, continue at this dose for the remainder of the study 2) Curcumin with piperine - week 0 - 150mg once daily, continue at this dose for the remainder of the study 3) Celecoxbi - week 0 - 200mg once daily, continue at this dose for the remainder of the study 4) Metformin - week 0 - 250mg once daily ; increased every week to achieve optimal dose of 500mg twice daily, continue at this dose for the remainder of the study 5) Quinapril - to be introduced on week 1 at 5mg once daily; increased every week to achieve optimal dose of 20mg once daily, continue at this dose for the remainder of the study 6) Propranolol - to be introduced on week 4; increased every week to achieve optimal dose of 40mg in the morning and 80mg in the evening, continued for the remainder of the study Renal function, complete blood count, blood pressure and pulse rate are monitored.
