Brief Summary:
A medication called temozolomide has been used for many years in the treatment of high-grade gliomas which are tumours that originate in the brain While this drug is the normal treatment for high-grade glioma a number of patients develop a side-effect which results in low levels of some important blood cells such as platelets or white blood cells If this side-effect occurs treatment with temozolomide may have to be stopped or paused which may affect how well this treatment works
At present it is unknown why some patients develop this side effect and others do not It is known that patients with a higher concentration of temozolomide in their blood are at an increased risk of developing this toxicity There may be some factors associated with the movement of the drug in the body or the removal of the drug from the body which may affect the concentration of temozolomide in blood There are many factors which may be involved including genes other medicines that are taken how well kidneys and liver are working or even the microbiome which is the bacteria in the gut
This study is being done to find out what these factors could be In the future this may lead to medical care teams being able to predict which patients are at higher risk of side-effects allowing them to implement measures to reduce the risk of this occurring

Detailed Description:
Concurrent with radiotherapy and adjuvant temozolomide TMZ is the standard of care treatment for high grade glioma however severe haematological toxicity is a major dose limiting factor impacting 16-45 of patients in different studies The investigators hypothesize that mechanistic factors such as genetic polymorphisms renal function or other patient factors such as sex concomitant medications or the microbiome result in this interpatient variability in toxicity This study aims to develop a pharmacokinetic model of temozolomide to test the effect of these potential covariates on TMZ concentration Part A in patients with brain tumours being treated with TMZ Using this model the investigators aim to assess patients who develop haematological toxicity from TMZ for mechanistic predictors of this toxicity Part B
The investigators hypothesise that the development of severe TMZ-induced haematological toxicity is due to higher exposure to temozolomide in plasma driven by mechanistic factors such as pharmacogenomic variants the microbiome or demographic factors
