This is a phase II, multi-centre, double-blind, placebo-controlled, randomised trial to compare the cannabinoid Sativex with placebo in patients with recurrent MGMT methylated glioblastoma treated with temozolomide (TMZ). The trial will randomise a target number of 234 patients on a 2:1 basis to receive either Sativex or Sativex-matched placebo, in combination with standard TMZ.~Patients will be followed up at 4-weekly assessments for a minimum of 52 weeks from the start of trial treatment or until death, whichever is sooner. MRI scanning will be performed at screening, week 10, week 22, week 30, then 3-monthly after commencing trial treatment as per standard practice.~The trial includes an initial feasibility study of 40 patients to confirm safety, compliance and achievability of planned target recruitment. There are no formal criteria for evaluation of feasibility but once 40 patients have been recruited, the independent Data Monitoring Committee will review the adverse event data, details on protocol treatment received, monthly recruitment rates and projected recruitment in order to make recommendations on trial continuation.~The current phase II trial design will enable potential expansion of recruitment into a phase III trial, should the emerging phase II results warrant this development.~The trial will be linked to the Tessa Jowell BRAIN MATRIX (TJBM) programme; utilising TJBM infrastructure, opening the same participating sites, and aligning the data collection and Quality of Life assessments already embedded in TJBM. This collaboration will allow data sharing within the platform thereby streamlining patient entry and provide additional oversight through TJBM. Patients recruited to TJBM who are potentially eligible for ARISTOCRAT may be identified and suggested to sites for consideration to the trial.
