Details and patient eligibility


The trial will compare the drugs olaparib and cediranib with standard chemotherapy in platinum resistant ovarian cancer. Patients will be randomised to one of three treatment groups: olaparib only, olaparib and cediranib and the control group paclitaxel. The aim is to compare efficacy of the 3 treatments and also how well each treatment is tolerated including the participants quality of life.

Full description

Olaparib is a PARP inhibitor which targets BRCA1/2 mutated tumour cells and cediranib is an anti-angiogenic drug which reduces blood supply to the tumour, suppressing tumour viability. Phase I/II trials of both drugs have shown these are well tolerated alone or in combination in ovarian cancer. The trial aims to compare the efficacy of the combination and of olaparib alone with paclitaxel chemotherapy and whether the olaparib/cediranib combination is better tolerated thus improving quality of life. Secondly standard paclitaxel chemotherapy must be administered weekly at hospital whereas the olaparib/cediranib combination can be administered at home potentially also improving patient quality of life. Participants' tumours will be resistant to platinum based therapies. Participants will be randomised into one of the 3 treatment arms after stratification for prior PARP/anti-angiogenic treatments/BRCA status. Participants will be on trial up to 18 months.

Inclusion criteria

  • Female patients, age ≥ 16 years with relapsed epithelial ovarian, primary peritoneal or fallopian tube cancer who have relapsed within 12 months of previous platinum-based therapy. Their most recent chemotherapy does not have to have been platinum-based.
  • Patients can have received prior PARP inhibitor, but there must be a > 6 month interval since treatment.
  • Patients can have received prior antiangiogenic therapy, but there must be a > 6 month interval since treatment; except for bevacizumab where a 6 week interval is required.
  • Measurable disease by RECIST Version 1.1 performed in past 4 weeks. At least one lesion, not previously irradiated, that can be accurately measured at baseline as ≥ 10 mm in the longest diameter (except lymph nodes which must have short axis ≥ 15 mm) with computed tomography (CT) or magnetic resonance imaging (MRI) and which is suitable for accurate repeated measurements.

  • Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
  • Written (signed and dated) informed consent prior to any study specific procedures and be capable of co-operating with protocol.

Patients must have

• Haemoglobin ≥ 9.0 g/dL and no blood transfusions in the 28 days prior to randomisation

Patients must have normal organ and bone marrow function measured within 14 days prior to administration of study treatment as defined below:

  • Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
  • Platelet count > 100 x 109/L
  • Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN)
  • AST (SGOT)/ALT (SGPT) ≤ 2.5 x institutional upper limit of normal unless liver metastases are present in which case it must be ≤ 5x ULN
  • Serum creatinine ≤ 1.5 x institutional upper limit of normal (ULN) or calculated creatinine clearance >50 ml/min calculated using Cockroft-Gault, Jelliffe or Wright (see Appendix 4)
  • Urine dipstick for proteinuria <2+. If urine dipstick is ≥ 2+ on two occasions more than one week apart then a 24-hour urine must demonstrate ≤ 1 g of protein in 24 hours or protein/creatinine ratio < 1.5.

Exclusion criteria

Negative urine or serum pregnancy test within 28 days of study treatment, confirmed prior to treatment on day 1. Pregnancy test will be performed monthly in women of child bearing potential.
