Paclitaxel, olaparib and cediranib in platinum-resistant ovarian cancer.
This is a trial in women with relapsed ovarian cancer that’s platinum resistant. It compares standard chemotherapy to either olaparib (Lynparza) only or olaparib with cediranib. This is a randomised trial, so you might be assigned either the standard chemotherapy or one of the two experimental treatments. Those assigned standard chemotherapy will be able to cross over to olaparib if their cancer progresses. Olaparib is an experimental drug, but is expected to be as active as and less toxic than chemotherapy.
Patients can find more details on the OCTOVA study page https://octova.octru.ox.ac.uk/. Clinicians with potentially eligible patients can review the inclusion/exclusion criteria below.
OCTOVA is being funded by an educational grant from AstraZeneca (AZ) as part of the AZ-ECMC alliance.

A patient will be eligible for inclusion in this study if all of the following criteria apply:
1. 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.
2.Patients can have received prior PARP inhibitor, but there must be a > 6 month interval since treatment.
3.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.
4.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.
5.Sufficient archival tissue confirming histological diagnosis available.
6.ECOG performance status 0-2.
7.Able to swallow and retain oral medications.
8.Life expectancy > 12 weeks in terms of disease related mortality.
9.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.
10.Written (signed and dated) informed consent prior to any study specific procedures and be capable of co-operating with protocol.
11.Patients must have haemoglobin ≥ 9.0 g/dL and no blood transfusions in the 28 days prior to randomisation.
12.Patients must have normal organ and bone marrow function measured within 14 days prior to administration of study treatment as defined in the protocol.
A patient will not be eligible for the trial if any of the following apply:
- Received previous single agent weekly paclitaxel for relapsed disease.
- Pregnant or breast-feeding women or women of childbearing potential unless effective methods of contraception are used during the trial and for 6 months after stopping treatment. 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. Postmenopausal is defined in the protocol.
- Treatment with any other investigational agent, systemic chemotherapy, or participation in another interventional clinical trial within 28 days prior to enrolment.
- Radiotherapy within 2 weeks from the last dose prior to study treatment.
- Started a stable dose of bisphosphonates for bone metastases less than 4 weeks prior to treatment with study drug e.g. patient is eligible and can continue to take bisphosphonates if these were started at least 4 weeks prior to treatment with study drug.
- Concomitant use of known CYP3A4 inhibitors.
- Concomitant use of potent inducers of CYP3A4.
- Persistent toxicities (>=CTCAE grade 2), with the exception of alopecia, caused by previous cancer therapy.
- Resting ECG with QTc > 470msec on 2 or more time points within a 24 hour period or family history of long QT syndrome.
- Blood transfusions within 1 month prior to study start.
- Patients with myelodysplastic syndrome/acute myeloid leukaemia.
- Patients with symptomatic, untreated, uncontrolled brain or meningeal metastases or tumour (see protocol for details).
- Major surgery within 14 days of starting study treatment.
- Patients who have not recovered from any effects of any major surgery.
- Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection.
- Any psychiatric disorder that prohibits obtaining informed consent.
- Left Ventricular Ejection Fraction (LVEF) < institutional lower limit of normal, when:
- Prior treatment with anthracyclines (excluding liposomal doxorubicin)
- Prior treatment with trastuzumab
- A NYHA classification of II controlled with treatment (see Appendix 2)
- Prior central thoracic RT, including RT to the heart
- History of myocardial infarction within the prior 12 months.
- Poorly controlled hypertension (persistently elevated > 150/100mmHg, either systolic or diastolic or both, despite anti-hypertensive medication).
- History of inflammatory bowel disease.
- History of cerebrovascular accident (including transient ischaemic attacks) within last 12 months.
- Gastro intestinal impairment that could affect ability to take, or absorption of, oral medicines including sub- acute or complete bowel obstruction.
- Evidence of severe or uncontrolled cardiac disease.
- Evidence of active bleeding or bleeding diathesis, as defined in the protocol.
- Known treatment limiting hypersensitivity to cediranib, olaparib, paclitaxel or any of its excipients
- Other psychological, social or medical condition, physical examination finding or a laboratory abnormality that the Investigator considers would make the patient a poor trial candidate or could interfere with protocol compliance or the interpretation of trial results.
- Any other active malignancy, with the exception of adequately treated cone-biopsied in situ carcinoma of the cervix uteri and non-melanoma skin lesions, requiring treatment/or whose prognosis will prevent readout from trial endpoints.
- Patients who are known to be serologically positive for Hepatitis B, Hepatitis C or HIV.
- Immunocompromised patients e.g., patients who are taking immunosuppressive drugs.

- Safety and tolerability of the combination of olaparib and cediranib
- Overall Survival
- Objective response rate
- Quality of Life
- Translational research (identification of potential biomarkers of response)
