E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the efficacy of cediranib in combination with oral gefitinib with cediranib alone. The primary outcome variable will be progression free survival as defined as the date from randomisation to the date of first progression or death due to any cause, whichever one comes first. |
|
E.2.2 | Secondary objectives of the trial |
• To document the safety and tolerability of cediranib in combination with oral gefitinib and cediranib alone. • To compare cediranib in combination with oral gefitinib and cediranib alone in terms of steroid sparing effects • To document the quality of life and neurological symptoms reported by patients taking cediranib in combination with oral gefitinib and cediranib alone. • To investigate the relationship between the effects of cediranib (+/- gefitinib) on levels of soluble angiogenesis biomarkers and clinical efficacy • To investigate the relationship between the patient’s genetic profile and efficacy of cediranib (+/- gefitinib) |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Provision of informed consent
• Age ≥18 years
• Life expectancy ≥ 12 weeks
• Histological/cytological confirmation of glioblastoma (WHO grade IV)
• Patients with measurable disease (contrast-enhancing tumour ≥10 mm by shortest diameter on 2 axial slices) by MRI imaging within 7 days prior to enrolment. (If patients have recently had a routine MRI scan, this should be assessed before deciding whether or not to screen the patient, and booking the screening/baseline MRI.)
• Patients must have been on no steroids or a stable dose of steroids (dexamethasone) for at least 5 days before the baseline MRI
• Patients must have completed standard first-line treatment for glioblastoma including surgery (with exception, if patient does not receive surgery as part of first-line treatment due to anatomical location, based on neurosurgeon’s assessment), cranial radiotherapy and chemotherapy with concomitant temozolomide. It is not essential that the entire Stupp regimen of 6 cycles of adjuvant temozolomide following chemoradiotherapy has been completed. The last dose of temozolomide must be more than 28 days from enrolment. Gliadel® wafers are permitted, as it is part of local treatment. No other previous treatment for glioblastoma is permitted (other than steroids).
• Patients must have a Karnofsky Performance Score of 70 or above
• Patients must have a mini-mental status examination score of 15 or greater
• Patients who require either oral anticoagulants (coumadin, warfarin) or low molecular weight heparin are eligible provided there is increased vigilance with respect to monitoring INR.
For inclusion in this genetic research, patients must fulfil the following criterion:
• Provision of informed consent for genetic research (separate consent required for tumour biopsy, blood sample, and post mortem donations) |
|
E.4 | Principal exclusion criteria |

• History of significant gastrointestinal impairment, as judged by the investigator, that would significantly affect the absorption of cediranib or gefitinib, including the ability to swallow the tablet whole
• Patients with a history of poorly controlled hypertension with resting blood pressure >150/100mmHg in the presence or absence of a stable regimen of anti-hypertensive therapy, or patients who are requiring maximal doses of calcium channel blockers to stabilise blood pressure
• Any evidence of severe or uncontrolled diseases (e.g. unstable or uncompensated respiratory, cardiac, hepatic or renal disease)
• Unresolved toxicity >CTC AE grade 1 from previous anti-cancer therapy (including radiotherapy) except alopecia (if applicable)
• Mean QTc with Bazetts correction >470msec in screening ECG or history of familial, long QT syndrome
• Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy
• Significant haemorrhage (>30mL bleeding/episode in previous 3 months) or haemoptysis (>5mL fresh blood in previous 4 weeks)
• Recent (<14 days) major surgery or brain biopsy. Recent craniotomy (<28 days) prior to first dose, or a surgical incision that is not fully healed
• Pregnant or breast-feeding women or women of childbearing potential with a positive pregnancy test prior to receiving study medication
• Known hypersensitivity to cediranib, gefitinib or any of its excipients
• History of other malignancies (except for adequately treated basal or squamous cell carcinoma or carcinoma in situ) within 5 years, unless the patient has been disease free for 2 years and they have tissue diagnosis of the target lesion
• Known infection with hepatitis B or C or HIV
• Involvement in the planning and conduct of the study (applies to both UCL CTC, AstraZeneca staff and staff at the study site)
• Past medical history of interstitial lung disease, idiopathic pulmonary fibrosis, drug-induced interstitial disease, radiation pneumonitis which required steroid treatment or any evidence of clinically active interstitial lung disease
• Previous enrolment as part of the present study
• Treatment with an investigational drug within 30 days prior to the first dose of cediranib/gefitinib
• Other concomitant anti-cancer therapy except steroids (dexamethasone only)
• Previous anti-angiogenesis (e.g. bevacizumab, sorafenib, sunitinib) therapy
• Previous anti-EGFR treatments (e.g. cetuximab, panitumumab or small molecule tyrosine kinase inhibitors etc.) or downstream targets mTOR inhibitors.
• Patients with evidence of any intratumoural or peritumoural haemorrhage deemed significant by the treating physician
• Patients who have received any form of cranial radiation within 3 months prior to study entry (excluding imaging)
• Patients who have progressed within 3 months of completion of standard cranial radiation
• Patients that have received radiosurgery or brachytherapy
• Patients on >8mg/day dexamethasone or equivalent steroids on any day of the 2 weeks prior to randomisation |

E.5 End points |
E.5.1 | Primary end point(s) |
Progression free survival (PFS) defined as the time from the date of randomisation to the date of first progression or death due to any cause, whichever one comes first.
Progression will be determined using site determination of performance status and a central review of the MRI scans, and by working to a modified version of the RANO criteria (Response Assessment in Neuro-oncology), see Wen et al 2010, as described in the protocol.

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
For regulatory purposes the end of the trial will be 6 months from the date the last patient finished trial treatment or the date the last patient dies, whichever is sooner. At this point it is judged that all relevant safety data and primary endpoint data will have been catured. Long term follow up will be continued until the last patient has died in order to capture all secondary endpoint data. |
