Current Primary Outcome Measures (submitted: March 14, 2013)

Incidence of Adverse Events as a Measure of Patient Safety. [ Time Frame: Study Day 1 - Day 358 ]

Adverse events will be coded according to the current medical dictionary for regular activities graded using the Common Terminology Criteria for Adverse Events criteria. The number of patients who experienced an adverse event whilst on treatment will be presented.

• Original Primary Outcome Measures: Same as current

Current Secondary Outcome Measures (submitted: March 18, 2013)

• The number of patients with Progression Free Survival at six months (PFS6) [ Time Frame: Study Day 1 - Day 190 ]
  PFS6 will be assessment at Visit 11 (Day 190). Progression of disease will be determined from Response Assessment in Neuro-Oncology tumour assessment (based on Magnetic Resonance Imaging scans). The number of patients with PFS6 will be presented for the individual treatment groups.
• Overall Survival [ Time Frame: Study Day 1 - Day 358 ]
  Overall survival will be assessed at the end of the treatment visit (Day 358 or at early termination). The number of surviving patients in each group from the randomisation phase (Part B) will be presented.

Descriptive Information

• Brief Title: A Safety Study of Sativex Compared With Placebo (Both With Dose-intense Temozolomide) in Recurrent Glioblastoma Patients
• Official Title: A Two Part Study to Assess the Tolerability, Safety and Pharmacodynamics of Sativex in Combination With Dose-intense Temozolomide in Patients With Recurrent Glioblastoma
• Brief Summary: An open-label phase to assess the frequency and severity of adverse events in recurrent glioblastoma patients receiving Sativex in combination with dose-intense Temozolomide (Part A). A randomisation phase to assess the safety of Sativex compared with placebo (Part B). Part B will be reported here.
• Detailed Description: Patients will receive Sativex and dose-intense Temozolomide in an open-label phase. The incidence of adverse events will be monitored (Part A). An investigator led Safety Review Team will assess the safety profile of the open-label patients and decide whether the study can progress to the randomisation phase (Part B). Patients who enrol in the randomisation phase patients will receive either Sativex or placebo. The safety of Sativex compared to placebo will be assessed by pharmacokinetic analysis of Temozolomide and its metabolites, clinical laboratory tests, adverse events and vital signs.
