This study seeks to (i) determine the safe dose of CYT997 when given in combination with carboplatin in patients with relapsed glioblastoma multiforme (glioma) and (ii) to determine whether the combination of CYT997 with carboplatin is a useful treatment for glioma.
||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||A Phase Ib/II Study of CYT997 in Combination With Carboplatin in Relapsed Glioblastoma Multiforme
Primary Outcome Measures:
- Safety and tolerability of escalating doses of CYT997 when given in combination with standard carboplatin therapy (Phase Ib component) [ Time Frame: Ongoing throughout therapy up until 30 days after last dose of CYT997 ] [ Designated as safety issue: Yes ]
- Progression-free survival at 6 months (PFS-6) utilising the dose of CYT997 identified in the Phase Ib component of this study (Phase II component) [ Time Frame: 6 months after initiation of therapy ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Objective response rate (ORR) [ Time Frame: Response is measured every second cycle of therapy ] [ Designated as safety issue: No ]
- Overall survival [ Time Frame: Baseline to study completion ] [ Designated as safety issue: No ]
- Safety and tolerability [ Time Frame: Measured continuously from study commencement through to 30 days after last dose of CYT997 ] [ Designated as safety issue: Yes ]
- Effects on pharmacodynamic markers of vascular disruption and tumour apoptosis [ Time Frame: Measured during first cycle of therapy ] [ Designated as safety issue: No ]
- Pharmacokinetic analysis of carboplatin and CYT997 in combination [ Time Frame: Assessed during first cycle of therapy ] [ Designated as safety issue: No ]

| Study Completion Date:
| Primary Completion Date:
||June 2011 (Final data collection date for primary outcome measure)
Escalating doses (100mg/m^2 to 150mg/m^2), 24-hour intravenous infusion on Day 2 of a 21-day cycle (Phase Ib component). Dose selected in Phase Ib component to be used for Phase II component.
Intravenous infusion over 1 hour at area under the concentration-time curve (AUC)=5 on Day 1 of a 21-day cycle
|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Patients who have received any other investigational agent in the preceding four weeks prior to commencing therapy in this study.
- Patients who have been previously treated with carboplatin.

- Patients who are receiving enzyme-inducing anticonvulsant drugs (EIACD) such as phenytoin or carbamazepine.
- Patients with a history of allergic reactions attributed to compounds of similar chemical composition to CYT997 or other agents used in the study.
- Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, cardiac arrhythmia or psychiatric illness/social situations that would limit compliance with study requirements.

- Presence of luminal stenosis of 50% or more in any of the extracranial or intracranial arteries supplying the brain, as measured by magnetic resonance angiography (MRA) at baseline.
- Patients with a baseline prolongation of the QTc interval of Common Terminology Criteria (CTC) grade 1 (QTc > 0.45- 0.47 sec) or greater.
Patients with impaired cardiac function or clinically significant cardiac diseases, including any one of the following:
- Left ventricular ejection fraction (LVEF) < 45% as determined by multigated acquisition (MUGA) scan or echocardiogram;
- complete left bundle branch block;
- obligate use of a cardiac pacemaker;
- congenital long QT syndrome;
- history or presence of ventricular tachyarrhythmia;
- presence of unstable atrial fibrillation (ventricular response > 100 bpm) Patients with stable atrial fibrillation are eligible, provided they do not meet any of the other cardiac exclusion criteria;
- clinically significant resting bradycardia (< 50 bpm);
- right bundle branch block + left anterior hemiblock (bifascicular block);
- angina pectoris = 3 months prior to starting study drug;
