Study information
Scientific title
A double-blind, placebo-controlled, three-arm, randomised, multi-centre Gynaecologic Cancer InterGroup trial of cediranib (AZD2171), in combination with platinum-based chemotherapy and as a single agent maintenance therapy, in women with ovarian cancer relapsing more than 6 months following completion of first-line platinum-based treatment
Acronym
ICON6 (International Collaborative Ovarian Neoplasm 6)
Study hypothesis
Current hypothesis as of 13/03/2015:
That cediranib has an influence on progression-free survival when comparing patients receiving chemotherapy alone with patients receiving chemotherapy and cediranib (AZD2171).
Previous hypothesis:
Over three separate trial stages the study hypotheses are:
Stage 1:
That it is safe to add a once daily tablet of cediranib to standard platinum-based chemotherapy
Stage 2:
That cediranib has an influence on progression free survival when comparing patients receiving chemotherapy alone with patients receiving chemotherapy and cediranib (AZD2171)
Stage 3:
1. That cediranib has an effect on overall survival when taken at the same time as chemotherapy (placebo versus active), and when taken at the same time and then continued as a maintenance treatment (placebo versus active)
2. If the first Stage 3 assessments shows the product is effective, that cediranib has an effect on overall survival when taken at the same time as chemotherapy compared with at the same time and then continued as a maintenance treatment

Condition
Relapsed platinum-sensitive ovarian cancer
Intervention
Current interventions as of 13/03/2015:
Patients in Arm A (the reference arm) will receive standard platinum-based chemotherapy plus a daily oral placebo tablet for the duration of the chemotherapy and then until protocol defined disease progression occurs.
Patients in Arm B (concurrent cediranib arm) will also receive standard chemotherapy plus daily oral cediranib during chemotherapy only, and then an oral daily placebo tablet until protocol defined disease progression or toxicity limiting treatment occurs.
Patients in Arm C (concurrent and maintenance cediranib arm) will also receive standard chemotherapy plus oral cediranib daily during chemotherapy and until protocol defined disease progression or toxicity limiting treatment occurs.
Previous interventions:
Patients in Arm A (the reference arm) will receive standard platinum-based chemotherapy plus a daily oral placebo tablet for the duration of the chemotherapy and then for up to 18 months from the time of randomisation, or until protocol defined disease progression occurs.
Patients in Arm B (concurrent cediranib arm) will also receive standard chemotherapy plus daily oral cediranib during chemotherapy only, and then an oral daily placebo tablet for up to 18 months from the time of randomisation, or until protocol defined disease progression or toxicity limiting treatment occurs.
Patients in Arm C (concurrent and maintenance cediranib arm) will also receive standard chemotherapy plus oral cediranib daily during chemotherapy and then continued for up to 18 months from the time of randomisation, or until protocol defined disease progression or toxicity limiting treatment occurs.
The starting dose of cediranib is 30 mg taken orally once daily. This will be down titrated if required on medical assessment to 20 mg and then 15 mg.

Primary outcome measure
Current primary outcome measures as of 13/03/2015:
Progression-free survival (PFS) in arms A vs C
Previous primary outcome measures:
Stage 1: Safety
Stage 2: Progression free survival
Stage 3: Overall survival
Data for the outcomes above will be collected approximately 3 weekly during chemotherapy, 6 weekly after chemotherapy up to 18 months, 3 monthly up to 3 years, 6 monthly during years 4 and 5, then annually until protocol defined disease progression or death.
Secondary outcome measures
Current secondary outcome measures as of 13/03/2015:
1. Progression-free survival (PFS) across arms A, B and C
2. Overall survival (OS)
3. Toxicity
4. Quality of Life (QoL)
Previous secondary outcome measures:
Stage 1: None
Stage 2: Overall survival and toxicity
Stage 3: Progression free survival, toxicity and quality of life
Quality of life assessment will be made using EORTC QLQ-C30 version 3 and EORTC QLQ-OV28. This information will be supplemented by health questionnaire EQ-5D. Other outcome measures will be assessed by clinical interview, blood tests and CT scans.
Data for the outcomes above will be collected approximately 3 weekly during chemotherapy, 6 weekly after chemotherapy up to 18 months, 3 monthly up to 3 years, 6 monthly during years 4 and 5, then annually until protocol defined disease progression or death.
