Study information
Scientific title
Multi-centre, randomised, double-blind phase II study comparing cediranib (AZD2171) plus gefitinib (Iressa, ZD1839) with cediranib plus placebo in subjects with recurrent/progressive glioblastoma (DORIC Trial)
Acronym
DORIC
Study hypothesis
This is a phase II, randomised, double-blind placebo-controlled study in patients with recurrent or progressive glioblastoma (WHO grade IV). Patients are to receive cediranib in combination with gefitinib or cediranib with placebo. The primary endpoint is Progression Free Survival.
Ethics approval

Intervention
This is a randomised double blind multicentre phase II trial of daily cediranib +/- gefitinib for patients with recurrent/progression Glioblastoma. Patients will continue treatment until confirmed progression, patient decision or the development of unacceptable toxicity. Follow up for the trial is continuous unless the patient requests otherwise. A translational component will examine the roles of potential biomarkers and stratify the results based on known indicators of prognosis such as MGMT methylation and IDH 1 and 2. Doses: Cediranib 30mg daily, Gefitinib 500mg or matching placebo daily

Eligibility
Participant inclusion criteria
1. Provision of informed consent
2. Age ≥18 years
3. Life expectancy ≥ 12 weeks
4. Histological/cytological confirmation of glioblastoma (WHO grade IV)
5. 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.)
6. Patients must have been on no steroids or a stable dose of steroids (dexamethasone) for at least 5 days before the baseline MRI
7. 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
7.1. It is not essential that the entire Stupp regimen of 6 cycles of adjuvant temozolomide following chemoradiotherapy has been completed
7.2. The last dose of temozolomide must be more than 28 days from enrolment
7.3. Gliadel® wafers are permitted, as it is part of local treatment
7.4. No other previous treatment for glioblastoma is permitted (other than steroids)
8. Patients must have a Karnofsky Performance Score of 70 or above
9. Patients must have a mini-mental status examination score of 15 or greater
10. 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.
11. For inclusion in the genetic research, patients must fulfil the following criterion:
11.1. Provision of informed consent for genetic research (separate consent required for tumour biopsy, blood sample, and post mortem donations)
11.2. If a patient declines to participate in any of the genetic research, there will be no penalty or loss of benefit to the patient
11.3. The patient will not be excluded from other aspects of the study described in this Clinical Study Protocol, so long as they consent to the main study

Participant exclusion criteria
1. Patients on enzyme-inducing anti-epileptic drugs within 2 weeks prior to study enrolment
Note: Patients are eligible if they switched to non-enzyme inducing agents and discontinued enzyme-inducing agents for more than or equal to 2 weeks prior to randomisation
2. Inadequate bone marrow reserve as demonstrated by an absolute neutrophil count ≤1.5 x 109 /L or platelet count ≤100 x 109 /L or requiring regular blood transfusions to maintain haemoglobin >9g/dL
3. Serum bilirubin ≥1.5 x ULRR (except for patients with known documented cases of Gilberts Syndrome)
4. ALT or AST ≥5 x ULRR
5. Serum creatinine >1.5 x ULRR or a creatinine clearance of ≤50mL/min calculated by Cockcroft-Gault
6. Greater than +1 proteinuria on two consecutive dipsticks taken no less than 1 week apart unless urinary protein <1.5g in a 24 hr period or UPC (Urine Protein: Creatinine) ratio <1.5
7. 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
8. 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
9. Any evidence of severe or uncontrolled diseases (e.g. unstable or uncompensated respiratory, cardiac, hepatic or renal disease)
10. Unresolved toxicity >CTC AE grade 1 from previous anti-cancer therapy (including radiotherapy) except alopecia (if applicable)
11. Mean QTc with Bazetts correction >470msec in screening ECG or history of familial, long QT syndrome

27. Patients with evidence of any intratumoural or peritumoural haemorrhage deemed significant by the treating physician
28. Patients who have received any form of cranial radiation within 3 months prior to study entry (excluding imaging)
29. Patients who have progressed within 3 months of completion of standard cranial radiation
30. Patients that have received radiosurgery or brachytherapy
