Titles & IDs
Public title
A randomised, placebo-controlled, trial of
concurrent cediranib [AZD2171] (with platinum-based chemotherapy) and concurrent and maintenance cediranib in
women with platinum-sensitive relapsed ovarian cancer.
Scientific title
ICON6 is a randomised three-arm, three stage, double-blind, placebo-controlled multicentre Gynaecologic Cancer InterGroup (GCIG) phase III trial, designed to evaluate the safety and efficacy of platinum-based chemotherapy in
combination with cediranib in women with platinum-sensitive relapsed ovarian cancer. Cediranib (AZD2171) will be administered
during platinum-based chemotherapy only (concurrent cediranib), or given during
chemotherapy and continued as single agent (maintenance therapy) for up to 18 months(concurrent and maintenance cediranib).

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Cediranib is an oral targeted small molecule inhibitor of a key signalling molecule and acts through blockade of a key receptor. Cediranib will be administered as a daily 20mg tablet (ie oral) during platinum-based chemotherapy only (concurrent cediranib), OR given as an oral 20mg tablet during chemotherapy and continued daily as single agent maintenance therapy for up to 18 months (concurrent and maintenance cediranib).
Intervention code [1] 4282 0
Treatment: Drugs
Comparator / control treatment
All patients, regardless of the arm they are randomised to, will be planned to receive 6
cycles of platinum-based chemotherapy. ICON6 patients are treated with carboplatin AUC6 over 30-60 minutes, in combination with paclitaxel 175 mg/m2 over three hours, three weekly for six cycles, assuming that the patient is fit enough to receive this. Those not be fit enough to receive combination therapy due to additional toxicity, or those patients who decline combination therapy will be eligible to receive six cycles of single agent carboplatin. This is considered 'standard therapy' in this group of women.

Outcomes
Primary outcome [1] 5321 0
Stage 2 primary outcome; progression free survivial (PFS).
If a minimal level of activity of cediranib based on PFS and overal survival (OS) is not detected, the trial could be stopped early. Analysis will be performed when both at least 50 deaths and at least 90 progressions or deaths have occurred in the reference arn (Arm A) which is anticipated after 150 patients are randomised to Arm A and 450 patients total randomised to Arms B and C.
Timepoint [1] 5321 0
Stage 2; 2 years after stage 1
Secondary outcome [1] 8950 0
Stage 3- progression free survival, toxicity and Quality of Life.
To evaluate the nature, severity and frequentcy of toxicities.
Quality of life will be assessed by patient self reported questionnaires administered during treament and three monthly until progression.
Timepoint [1] 8950 0
Stage 3; 6 years
Secondary outcome [2] 241557 0
Stage 2- overall survival and toxicity.
Determined by seeing whether a minimal level of activity of cediranib can be detected by comparing OS in patients receiving chemotherapy alone (Arm A) with PFS in patients receiving chemotherapy and cediranib (arm B plus C).
Timepoint [2] 241557 0
Stage 2; 2 years after stage 1

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is concealed because central randomisation is by phone /fax /computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Other design features
After stage 1 (safety): if there are more than 15% of patients with grade 3 or 4 adverse events the study could be stopped or modified.
Stage 2 (activity). If a minimal level of activity of cediranib was not detected after 600 patients wererandomised, the trial could be stopped early.
